摘要： 243,057. Johnston, J. M. T., and Davies, J. E. Aug. 19, 1924. Rotary apparatus; feeding gases, controlling direction of flow of. - Apparatus for drying sand, gravel, &c. has the outlet 3 for the furnace gases filled internally with a helical baffle 5 which imparts a whirling motion to the gases, the dust thus separated passing through louvered openings 9 in the wall of the duct into a chamber 11 leading back to the drier 15. The gases exhausted from the drier by a fan pass upwards through the duct and serve to heat the material descending in the chamber 11 which thus constitutes a feed-hopper.

摘要： 396,506. Anemometers. CLEVELAND, F. J., 29, Southampton Buildings, London.- (Davies, J. E. ; Oorgaum, Mysore, India.) April 28, 1932, No. 12249. [Class 97 (iii).] To measure the velocity of low-speed gas currents, means for producing a naked flame are provided in conjunction with means for reading off the angular displacement produced by the current. In the form shown, a base plate 1, carrying a quadrant 2, which may be graduated in velocities, and a spirit level 3 adapted to be viewed through an aperture 4, is provided on an extension 5 with claws 6 for gripping a candle or a lamp comprising a reservoir 7, cap 8, and wick 9.

摘要： 241,281. Johnston, J. M. T., and Davies, J. E. July 17, 1924. Rotary apparatus; agitating appliances. - The rotary drying drum for sand, gravel or stones is provided with internal blades fixed to the wall of the drum and each in the form of a scroll having both edges free and the concave side facing in the direction of rotation of the drum, the blades extending to a point within half the radius of the central axis of the drum. The scrolls may be arranged so that the inner ends are in advance of the roots in the direction in which the material travels through the drum . Four sets of blades are arranged along the length of the drum 6 one blade only of each set being shown in Fig. 1, and each set comprises four spiral blades 7 each twisted so that its surface lies at an angle to the axis of the drum and its inner end lies in advance of its root. Angle-iron strips 9 are secured to the rear edges of the blades and are extended beyond the roots at 10 to form feed members which transfer the material from one set of blades to the next and further feed blades 111 may be fitted between the sets of blades 7 for this purpose. Material fed through a shoot 15 is thus passed through the rotating drum and delivered to discharge blades 11 from which it drops into a discharge hopper 13. Triangular apertures 14 may be provided in the wall of the drum beneath the roots of the blades for the outlet of vapour. The blades may be roughened or perforated to break up material which tends to cake during drying. Specifications 223,042 and 241,290 are referred to.

摘要： 290,714. Davies, J. E. Feb. 15, 1927. Holding tools.-A device for manipulating screws and small tools such as bradawls, screwdrivers, gimlets, files, scribers, &c. in positions of difficult accessibility, comprises a wire b of half-round section which is doubled on itself to constitute forceps, the jaws being closed by a sliding ring e. The jaws are axially recessed at c and transversely notched at d to receive a screwhead, or a bradawl &c. shank having a laterally projecting driving pin. The forceps may be left free at their junction end, or may be fitted into a handle, which may be hollow to accommodate small tools not in use. The device may be lengthened by means of an extension tube or bar carrying the handle at one end and the forceps at the other. The whole device may be encased in or constructed of an insulating material such as that sold under the registered Trade Mark " Bakelite. "

摘要： 257,121. Johnston, J. M. T., and Davies, J. E. May 19, 1925. Density separators;; discharging.- A centrifugal dustseparator comprises a centrifugal fan 9 the volute casing of which is provided with louvre openings 5 which face the direction of rotation of dust-laden gas and through which dust passes to a collecting chamber 11 surrounding the fan-casing. The louvre openings may be parallel to the fan axis or at an angle thereto and may be adjustable in width either individually or simultaneously by means of slidable plates 15 which overlap the unbent edges of the openings. For simultaneous adjustment these plates may be secured to chains surrounding the fan-casing and attached to bolts outside the casing. The dust is removed from the collecting chamber 11 by a, worm 13. A throttle valve 37 is fitted in the gas outlet. Specification 236,452 is referred to.

摘要： 244,975. Johnston, J. M. T., and Davies, J. E. April 1, 1925. Tar-macadam, plant for making.- Relates to apparatus, for use particularly in drying, heating, and mixing granular materials for road making, of the kind comprising a rotary drum 1 arranged within a heating casing 2, and consists in providing a floating baffle 5 between the casing and the drum. The baffle forms a continuation of a fixed partition 3 and consists of a ring 5 having radially adjustable overlapping plates 6 and is supported clear of the drum by rollers 10 mounted upon pins 12 passing through slots in the partition 3. Specifications 223,042. and 241,290, [Class 34 (ii), Drying systems &c.], are referred to.
