    • 922,281. Valves. R. W. YOUNG. April 9, 1959 [April 10, 1958], No. 11341/58. Class 135. Gas pulses are obtained by pressurizing in sequence a number of outlets 38 of a pulsator that is put into operation upon opening an adjustable needle valve 57 connected to a gas supply line 55; the latter is also connected to ports 23, 31. Gas in port 23 flows through a fixed or adjustable restrictor 24 into a chamber 21 and from port 31 into a chamber 26 to act on a diaphragm 27 connected to a diaphragm 22 in the chamber 21 by a member 28, and due to the difference in areas between these diaphragms, the latter and member 25 are lowered to close off a port 30 between the port 31 and chamber 26, concomitantly gas from the valve 57 passes into a chamber 9 until the pressure therein is sufficient to cause a spring-loaded diaphragm 6 to close a port 4 and shut-off the connection between a chamber 15 beneath a diaphragm 16 and a vent opening 3 via a passage 5 and port 4 whereby pressure builds up in chamber 15, since it is open to the chamber 21 through a restriction 25 until it lifts the diaphragm 16 and opens a port 17 so interconnecting chambers 15, 21 and producing a pressure drop in the latter. The pressure differential across diaphragms 22, 27 is thereby altered and these diaphragms are elevated to open port 30 and connect the port 31 to the one outlet 38 selected by a rotary valve 32 and via a passage 47 and a flap non-return valve 48 to a chamber 45, causing displacement of a diaphragm 46 and hence of a pawl 40 to move valve 32 over the next outlet 38. Continued lifting of diaphragm 16 also unseats a valve 11 and vents chamber 9 via a port 14, the resulting pressure drop in the chamber enable the diaphragm 6 to open port 4 and so exhaust the chamber 15; the diaphragm 16 closes port 17 and gas flowing through the restrictor 24 moves the diaphragms 22, 27 to close port 30 and the cycle of operations is repeated. When the port 30 is closed, gas in chamber 45 bleeds to atmosphere through a restrictor 52 to produce a downward movement of the diaphragm 46 to cause motion of the rotary valve 32 into a position to connect the next gas pulse to another outlet 38. Each outlet 38 leads to one or more blast valves 60 comprising three diaphragms 65-67 forming chambers 61-64; chamber 61 is connected to line 55 and has an outlet 70 normally sealed by a closure member 73, the latter having all three diaphragms attached thereto. When a pulse is delivered through the outlet 38 it acts differentially on diaphragms 65, 66 and overcomes the differential force produced by the supply pressure in chambers 61, 64 to unseat member 73 and connect an outlet 70 with the line 55. When the pulse ceases the pressure in chamber 62 bleeds away through an adjustable port 74. Chamber 63 is open to atmosphere by way of a vent 77. The supply and pulse gases and pressures may be different.

    • 623,909. Spring suspensions ; vehicle underframes. V. P. SHEET METAL, Ltd., YOUNG, R. W., and JENKINS, H. L. May 27, 1947, No. 14101. [Class 108 (ii)] A spring suspension for a sidecar chassis comprises a torsion bar having one end connected to the wheel stub axle and the other end adjustably connected to the chassis frame. A tube 12 forming part of the chassis and disposed parallel with, and transversely of, a transverse tubular chassis member 1, is rigidly connected at its end nearest the cycle, to an adjusting lever 20 and at its opposite end, to a lever 18, connected through a link 17 to a lever 16. The latter is pivoted at one end on a spindle 15 passing through the top corner of a triangular-shaped box member 14 which also connects together the tubes 1 and 12 at their ends nearest the wheel 3 of the sidecar. The other end of the lever 16 carries a stub axle for the wheel 3. The angular position of lever 20 is adjustable by means of a hand wheel 41, Fig. 6, on a screwed rod 21, passing through the end of the lever and pivoted to the tube 1. In a modifiction (Fig. 7, not shown), the lever 16 is forked and is provided with bushes which may be of the porous type to form a bearing on the spindle 15 which is extended on each side of the triangular box member 14. In a further modification (Figs. 9, 10 and 11, not shown), the forked lever is built up from pressed sheet metal members by welding and is provided with similar bushes for bearing on the pivot spindle. The torsion bar tube 12 may alternatively be arranged in front of the tube 1 or above it In the latter arrangement, the lever carrying the stub axle is secured directly to the end of the torsion bar and the box member 14 is replaced by a member of simple construction. The sidecar chassis may be of metal girder, sheet metal, composite or other construction. In this case the torsion bar 19 is located adjacent a transverse frame member.

    • In a data processing method and apparatus, an image signal representative of features in a space of two or more dimensions is progressively filtered at monotonically increasing filtering scales, the signal being input to the first filtering scale, and the input to the or each subsequent filtering scale is the output signal from the previous scale. Each input has a number of data samples each of which represents a respective region of the space, and at each filtering scale those samples are sorted into connected-sets, each of which contains a plurality of substantially equal value to data samples or a respective individual data sample not in other sets. The process then selects those connected-sets which contain data samples having values which are local maxima or local minima and which represent a composite region of a size related in a predetermined way to the current filtering scale. Each selected set is then effectively merged with the adjacent connected-set which contains data samples of a value closest to that of the sample(s) in the selected connected-set. This is achieved by changing the latter's value to that of the samples in the adjacent connected set. The output signal for the filtering method is derived from the output of at least one of the filtering scales. In at least one of those scales, both connected-sets having local maxima and connected-sets having local minima are selected, thereby increasing the tolerance of the method to noise.
