Title: Improvements relating to foot valves for compressed air tractor-trailer braking systems
IPC: B60T15/04
Filed: 1953-12-03
Abstract: 732,959. Fluid-actuated valves. WESTING- HOUSE BRAKE & SIGNAL CO., Ltd. Dec. 3, 1953 [Dec. 22, 1952], No. 33582/53. Class 135. [Also in Group XXXIV] A pedal-operated driver's brake control valve for tractor-trailer vehicle units comprises a casing 1 within which are aligned pistons 2 and 3. The space 38 between the pistons is connected by port 36 to the trailer brake pipe. Annular spaces 21 and 22 formed in the piston 3 are connected respectively by ports 33 and 34 to the tractor and trailer reservoirs and space 39, below piston 3, to the trailer brake pipe by connection 35. Depression of the pedal 10, resisted by spring 19 seated on a fixed abutment 20, causes a self-lapping action of the valve 28 allowing exhaust through passage 18 and port 14 to atmosphere, and the valve 29 allowing fluid to pass from the trailer reservoir to the trailer brake pipe. A similar action with respect to the tractor takes place with valves 281 and 29<SP>1</SP>, but since the adjustable spring 31 must first be compressed before the exhaust port 15 is cut off, the tractor brakes are applied after, and at a lower pressure than the trailer brakes. In the event of a break in the trailer pipe, connected at 36, the piston 2 will force the piston 3 downwardly to operate the tractor brakes by direct mechanical action through the flutes 17.

Title: Improvements in or relating to releasable fastening devices
Inventor: CHANARYN VICTOR
IPC: E05B65/32
Filed: 1958-10-22
Abstract: 927,222. Latches. WILMOT-BREEDEN Ltd. Oct. 15, 1959 [Oct. 22, 1958], No. 33712/58. Class 44. A push-button linkage for producing a positive turning movement of one of two interengaged latch parts during a releasing operation, comprises two interengaging lever arms, one provided with a cam surface which co-operates with a surface of the other with a camming action, the effective length of the lever arm transmitting torque to the lever arm which it engages progressively increasing relative to the effective length of the latter lever arm during an operative movement of the pushbutton. When the stem of an external push-button engages an abutment surface 13a of a lever 12 pivotally mounted on a back-plate 1 a lever arm 17 engages with a second lever arm 9 of a spring-loaded camplate 7 to the other side of which is integrally attached a cam 2. As the lever 12 rotates clockwise, Fig. 3, surfaces 18 and 19 of the lever arms contact with an increase in the effective length of the lever arm 17 and a decrease in the effective length of the lever arm 9. The increased leverage thus required to rotate the cam is offset by the pressure exerted by the door seals on the cam 2 through jaws 5 and 6 of a keeper engaging the cam, so that the resultant effort required on the push-button is approximately constant. A remote-controlled releasing mechanism includes a lever 24 whose arm 27 contacts the cam-plate 7 to rotate the cam. A locking lever 28 is also provided, which in its operative position prevents movement of an arm 15 of the lever 12. Specifications 864,305 and 871,895 are referred to.

Title: Improvements in processes and plant for the manufacture of cement
IPC: C04B7/40
Filed: 1921-12-19
Abstract: 199,056. Rigby, T. Dec. 19, 1921. Spray evaporators.-Cement materials in the form of slurry or powder are dried before admission to the kiln by being dispersed and carried in suspension in a rapidly moving current of hotgases from the kiln. The dried material is separated from the gas current by cyclone separators or filters or both followed by washing, preferably with slurry. Part of the gas may be recirculated through the apparatus, or the kiln gases may be diluted with air, and the recirculated gas or air may be heated in the clinker cooler. Before entering the drying-apparatus the kiln gases may be used to generate steam, which may be used, either directly or after driving an engine, to operate film driers arranged as described in Specification 194,738, which operate on the slurry in series or in parallel with the main drying system. In a form of the apparatus for drying slurry, gases from the kiln 3 are drawn by a fan 7 through a vertical shaft 13, 15, up which a spray of slurry is directed from a jet 19, and thence through a lengthy flue 17 to a battery of cyclone separators 61 from which the dried material is delivered, optionally through briquetting-rolls 67, to the kiln. The jet 19 is situated in a downwardly projecting branch 25 of the vertical shaft which dips into the slurry tank 27 supplying the jet, and it is surrounded by a hood 21, Fig. 2, which can be raised or lowered relatively to the jet to control the spray. To remove deposit from the sides of the vertical shaft, the lower part 13 revolves against a fixed internal scraper 41, and the upper fixed part 15 contains a number of revolving scrapers 43. The scrapers may be replaced or supplemented by a hammering or vibrating device, or the walls of the shaft may be enamelled to reduce deposition. Material deposited at the top of the upright shaft is caught by a travelling band 51 and returned to the gas current by a scraper 57. The gas leaving the separators may be recirculated through the drying apparatus via the flues 69. 77, and air may be admitted at 81. Gas leaving the system by the flue 71 is washed in the scrubber 75 with a spray of slurry which is passed to the tank 27. Before entering the drying system the gas may traverse the flues of a boiler 104 supplying steam to the engine 118 and the film driers 100, 102 which dry a separate portion of slurry, the dried product being fed to the briquetting-rolls by the conveyer 137. When the process is used for drying powdered materials these may be dispersed in a current of cool air or gas before mixture with the hot gases.

Title: Improvements in or relating to a process for the manufacturing of compound compressed plates made of layers of pieces of wood and binding materials and compound compressed plates made according to the said process
IPC: B27N3/00
Filed: 1945-12-27
Abstract: 608,252. Plywood. FAHRNI, F. Dec. 27, 1945, No. 34950. Drawings to Specification. [Class 145 (ii)] Plywood sheets are made by arranging a layer of small wood chips coated with a binder between two layers of shavings also coated with a binder, and compressing the whole under heat to consolidate it. The chips are preferably from 5 to 50 mm. in length, 3 to 10 mm. in width and 1 to 5 mm. in thickness, and the shavings from .5 to 5 sq. cm. in area. Water may be added to the materials of the layers, more water being added to the shavings than to the chips, and a greater proportion of binder may be added to the shavings than to the chips. The shavings may also be coloured. In preparing the sheets, a frame may be reciprocated beneath a hopper to receive a number of thin layers of the binder coated shavings, and then reciprocated beneath a shoot down which the chips fall. The frame is again reciprocated beneath a hopper to receive the final layers of shavings. The layers are then subjected to pressure of from 5 to 25 kgs. per sq. cm. at a temperature of 120‹ to 150<SP>0</SP> C. Alternatively, the layers may be cold pressed in the frame, and then removed from the frame and compressed under heat. In one example, the chips are dried to a water content of 5 per cent by weight, water-proofed by treatment with 2.5 per cent of paraffin and then mixed with 3.5 per cent of a powdered urea-formaldehyde resin, and with a liquid hardening agent such as nickle nitrate solution. The shavings of white soft wood are coated with 14 per cent of a binder and sprinkled with water to give a water content of 18 per cent. In a second example, 800 parts by weight of chips dried to 4 per cent humidity are mixed with 32 parts of a binder as in the first example. The shavings. are dried to 10 per cent humidity and 150 parts by weight are mixed with 50 parts of finer hardwood shavings and the mixture treated with 20 parts of a urea or melamine condensation product and 20 parts of water; 10 parts of a powdered hard wax are then added. The plywood prepared as in this example is suitable for flooring and quartz powder or plaster may be added to at least one outer layer to give it a non-slip property.
