    • 751,846. Counting apparatus; transfer mechanism; turnstiles. SMITH, H. J. Feb. 5, 1954 [Nov. 5, 1952], No. 27864/52. Classes 106 (1) and 106 (3). A turnstile electrical entry registering apparatus comprises a pair of switches actuated respectively, by means associated with the turnstile, at the beginning and end of a rotary movement of the turnstile and electrical counting means operated by the successive operation of said switches. The arrangement is such that oscillation of the turnstile about its normally closed position does not effect actuation of the switches. The normally open switch K1, Fig. 1, and the normally closed switch K2 are connected to the relay T/4 as shown. At each entry the turnstile moves through 90 degrees and a cam fixed thereto first closes the switch K1 then towards the end of the turnstile movement the cam opens the contact K2. 'Upon closing of K1 relay T/4 is energized and by closing T1 establishes a selfholding circuit through K2. Delayed action relay M/1 is energized by closing of T3 and closes M1. Upon de-energization of relay T/4 to close T2 the driving magnet UDM of the first order of a counter comprising rotary selector switches U, D, C, M is energized and the counter is thereupon stepped on by one unit. During the energization of T/4 an alarm lamp is lit. The rotary selector switches each have four banks of contacts, the first banks U1, D1, C1, M1 are connected to indicator display lamps, the second banks U2, D2, C2, M2 are interconnected for transfer between denominations, the wipers of the third banks U3, D3, C3, M3 are connected to the assigner means of a grand total counter common to a number of turnstile counters and the fourth banks U4, D4, C4, M4 are used in zeroizing the turnstile counter. The grand total counter comprises a pair of assigners, only one of which is shown, formed by a rotary selector switch CA having four banks CA1, CA2, CA3, CA4, Fig. 4, and a pair of impulsers or collectors, only one of which is shown, formed by a rotary selector switch CP having three banks CP1, CP2, CP3. Associated with the assigner switch and collector switch are the relays ST, A, S, RH, I. The arrangement is such that the assigners CA and impulsers transmit in succession the " units " and " tens " registration and simultaneously the " hundreds " and " thousands " registration of each turnstile counter in succession to a grand total counter also comprising rotary selector switches.

The starting of a power press by means of a fluid-pressure actuated clutch having an actuating cylinder 34, Fig. 3, controlled by a starting valve 36, which may be actuated electrically under control of a suitable push button, is further controlled by a switch 15, Fig. 2, in the electrical starting circuit and a pilot valve 29 which controls pressure fluid to a cylinder 31 to actuate inlet and exhaust valves 37, 38 to the clutch cylinder 34. The switch 15 and valve 29 are actuated through linkage 18, 17, 13, 12 and 9 from a cam groove 7, 8 on a vertically moving guard 1 so that unless the guard is fully closed the switch 15 is held open and the valve 29 actuated to exhaust the clutch cylinder 34 to prevent operation of the press. When the guard is closed the switch 15 is closed and lever 18 is moved longitudinally to allow a plunger 23 of the valve 29 to move into a hole 40 which conditions the system for starting on operation of the valve 36. The hole 40 in the lever 18 being engaged by the plunger 23 also prevents the guard being opened during the working stroke of the press. In order however to allow the guard to be raised before the press slide actually reaches its top position on the return stroke when it is stopped by the usual limit switch operated from the crankshaft the lever 18 is also controlled by a cam disc 20 on the crankshaft having low and high portions acting on a roller 19 on the lever. When the high portion is acting the lever 18 is raised and the plunger 23 is either raised to prevent actuation of the press or engaged in the hole 40 to prevent raising of the guard. When the roller 19 drops onto the low portion which is arranged to correspond to the return movement of the slide the lever 18 falls to release itself from the plunger 18 and thus allow the guard to be opened although the slide may not be quite at rest. The starting valve 36 may be directly operated by hand and the stopping of the press effected by the actuation of a valve by the cam device. The switch 15 is also replaced by a valve in this case.

[Classes 78 (iii) and 78 (iv)] In a combination of a road vehicle and a rail vehicle for carrying it, in which the rail vehicle provides a platform on to which at least one pair of road wheels adjacent one end of the road vehicle may be run in a direction transverse to the rail vehicle, and in which the combination provides means whereby the other end of the road vehicle may be supported and swung laterally over the rail vehicle to bring the vehicle in line, is characterized in that the rail vehicle has a turntable on to which the said road wheels are run and which may then be rotated during the swinging operation. As shown in Figs. 1 and 2 the rail vehicle comprises a four-wheeled truck 11 having a flat well 12, part of which is formed by a turn-table 13 having an extending portion 14 adapted to overlie the gap between the truck and a fixed ramp or platform. The rear wheels of the semi-trailer shown may be run up the ramp and over the portion 14 of the turn-table 13 to be guided by a ramp 14a so that automatic latches 15 on the turn-table engage the axle of the semi-trailer when it lies over the axis of the turn-table. The front of the semitrailer when detached from its tractor is supported by pairs of jockey wheels 17 which may be fixed with their axes intersecting the axis of the turn-table 13 or may castor. The jockey wheels may be driven by a detachable handle on the shaft of a worm shown in Fig. 4, the worms for the two pairs of jockey wheels being coupled by a shaft 22, or by power means. When the jockey wheels are so driven the semitrailer is turned about the axis of the turntable 13 until the semi-trailer lies wholly upon the rail vehicle, as shown in Fig. 1. Hinged bridge-plates 16 on the rail vehicle facilitate this movement. When in position on the rail vehicle the semi-trailer is held by automatically engaging catches 25 (Fig. 1) and the weight of its forward end is transferred to a jack 26. As shown in Fig. 4, the axles 18 supporting the jockey wheels 17 may be retracted by manuallyoperated jacks 19. U.S.A. Specification 1,968,196 is referred to.

    • Cellulosic artificial silk materials, e.g. fabrics formed from viscose rayon, acetate rayon or cuprammonium rayon, are chemically modified by impregnating them with a solution or dispersion of pyruvic aldehyde in the presence of an organic acid and thereafter heating the impregnated material, e.g. from 120 DEG to 100 DEG C. for 5 minutes. The impregnated material may be stretched to its original dimensions and may be maintained so stretched during the heating operation. In an example, a viscose rayon fabric is impregnated with a solution of 12.3 parts by weight of pyruvic aldehyde and 1.5 parts by weight of oxalic acid in 288 parts by weight of water, stretched to its original dimensions and dried. The fabric is then heated at 140 DEG C. for 5 minutes and bleached with aqueous sodium hypochlorite solution.ALSO:Cellulosic textile materials, e.g. fabric formed from cotton, viscose rayon, acetate rayon, or cuprammonium rayon in the form of mono-or multi-filament or staple fibre yarns, are dimensionally stabilized to laundering by impregnating them with a solution or dispersion of pyruvic aldehyde in the presence of an organic acid and thereafter heating the impregnated material, e.g. from about 120 DEG C. to about 160 DEG C. for about 5 minutes. The impregnated material may be stretched to its original dimensions and may be maintained so stretched during the heating operation. In an example a viscose rayon fabric is impregnated with a solution of 12.3 parts by weight of pyruvic aldehyde and 1.5 parts by weight of oxalic acid in 288 parts by weight of water, stretched on a tenter to its original dimensions and dried. The fabric is then removed from the tenter, heated at 140 DEG C. for 5 minutes and bleached with 0.5 Tw. aqueous sodium hypochlorite solution. The process is said to be especially applicable to regenerated cellulosic materials. The pyruvic aldehyde may be applied as a solution or dispersion in an organic liquid and the organic acid used may be acetic or tartaric.

[Class 80 (ii)] A low-drag ratchet-clutch for cycles and other purposes, which allows overrun in both directions without pawl contact, comprises a double-toothed pawl 10, pivoted on a floating carrier-plate 8 and pressed by a blade-spring 12 into permanent engagement with internal ratchet-teeth in a freely-mounted driving sprocket-ring 20, and out of engagement with oppositely-inclined external ratchet-teeth on a coaxial inner driven ring 5 which may be connected to a final driven hub 2 either directly, or, as shown, through a subsidiary pawl-and-ratchet clutch 6a, 5a. As shown, the main pawl 10 has a side-lug 18 engageable with one of a series of facial spiral grooves 19, Fig. 3, in a stationary side-plate 17 so that under forward drive-torque, the pawl lug rides down and finally out of a groove to bring the pawl into engagement with the driven ratchet-ring 5 whilst still maintaining engagement with the driving ratchet-ring 20, thus transmitting a one-way drive therebetween. On cessation of drive-torque, the blade-spring 12 disengages the pawl 10 entirely from the driven ratchet-ring 5 only, leaving the driven member free to rotate in either direction without any resistance from the pawl, the lug 18 of which moves into and remains in one of the fixed grooves 19 until forward drive is resumed. For driving in opposite directions, a pair of ratchet clutches, as above, may be mounted on a common shaft, with their driving members integral ; driven independently or having wormteeth for engagement with a common driving worm.

[Class 140] Nylon fabrics are rendered water repellent by treatment with a conventional reagent such as a heat decomposable long-chain quaternary ammonium compound or a wax, the material being subjected to a hot calendering operation either before or after the treatment with the reagent. The nylon fabric is passed through a dispersion of the quaternary ammonium salt of a wax emulsion, the excess liquid expressed between rollers and, in the case of the quaternary ammonium salt, baked, washed in soap solution and dried. In the case of the wax dispersion the fabric is only dried. The fabric so treated is heavily calendered at above 80 ‹C. on both back and face. In a modification, the nylon fabric is calendered before being treated in an emulsion of the wax, e.g., that known under the registered Trade Mark Dipsanil V, and dried. The fabrics are used for umbrella covers, lightweight weatherproof garments and splashproof curtains. Suitable waxes include the paraffin waxes for which benzene and volatile paraffins are suitable solvents.
