Abstract: 485,490. Furniture frames. BROOKS & CO., Ltd., J. B., and JAMES, J. N. Jan. 13, 1937, No. 1001. [Class 52 (ii)] In a chair, stool, table, stand or the like, the upper ends of several legs pass into a box or encircling member, and means are provided for clamping the legs against the inside of the box, the seat or top of the stool or the like being supported on a central rod passing into or through the box or a part disposed within the box. The four tubular, angle- or channelsection metal legs 1. Fig. 5, are pressed into engagement with the lower inside edge of the metal box 2 by a cross-shaped plate 4, the cut-out at each corner of the plate being provided with flanges 11 so as to engage the inside of the legs. The upper ends of the legs are cut into semicircular steps 1a, Fig. 3, and incline inwards so as to engage holes 8 in a plate 3, which rests inside the box on lugs 9. The plates 4, 3 are drawn together by a sleeve 5, which engages the plate 4 by means of a flange 12 and the plate 3 by means of a nut 13. The upper ends of the legs are flush with the upper face of the plate 3. The sleeve 5 may be welded to the plate 4. The sleeve 5 is screwthreaded internally so as to engage a thread on the supporting pillar for the seat of the chair, or the like ; the thread stops some distance from the top of the sleeve so that the pillar cannot become disengaged from the sleeve by accident. The box may be provided with a cover cap. Specification 245,601, [Class 52 (ii)], is referred to.

Title: Improvements in or relating to brake arrangement
IPC: B61H5/00
Filed: 1946-01-11
Abstract: 608,779. Supports for disc brakes. BUDD WHEEL CO. Jan. 11, 1946, No. 1007. Convention date, Jan. 8, 1945. [Class 103 (i)] In supports for the non-rotating friction members of vehicle brakes and the actuating means therefor, comprising a transverse part pivotally supported from the vehicle frame and longitudinally extending arms at the ends which are supported on a wheel axle, the parts that are connected to the axle are so formed that the arms become automatically detached from the axle when the wheel and axle assembly is dropped away for disassembling. As shown, the side members 2 of the truck frame of a railway vehicle are supported by springs 4 upon equalizers 5 that bear on the axle boxes 7 guided for relative vertical movement by pedestal guides 8. To remove a wheel and axle assembly 9, 10, the equalizers may be jacked up so that the wheel and axle in effect drops away from the other parts of the truck. Brake shoes 12 for engagement with discs 11 secured to the axle 9 are carried by levers 13 pivoted at 14 in housings 15 carrying actuating cylinders for the levers and which form parts of a support comprising a transverse part 16 and arms 17. The part 16 is pivotally supported in a bearing 19 secured to the frame transom 3. The arms 17 have parts 27, 28 which bear on a part 26 of the axle boxes 7, the part 27 being disposed substantially vertically above the axle and the part 28 at one side of the vertical plane through the axle, the arrangement of the bearings being such that while adequate support of the arms on the axle boxes is provided, the members 27, 28 are not far enough apart to prevent the dropping away of the wheel and axle assembly and the automatic disengagement of the members from the axle boxes. Rubber cushions 31 may be disposed between the members 27, 28 and the arms 17 to permit slight movements between the parts and to aid in cushioning road shocks. The part 16 of the brake support is mounted in a rubber cushion 21 secured within a bracket 19 bolted to the transom 3 in such a manner as to permit free vertical swinging movement of the arms 17 while cushioning vertical, longitudinal, transverse and tilting movements of the support relatively to the vehicle frame. Specification 546,692 is referred to.

Title: Improvements in or relating to liquid-liquid contacting apparatus
Inventor: TANNER MAURICE CHARLES
IPC: B01D11/04
Filed: 1957-01-10
Abstract: 831,383. Mixing apparatus. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Dec. 30, 1957 [Jan. 10, 1957], No. 1011/57. Class 86 Mixing apparatus for liquids comprises a pair of tubes dipping into a mixing compartment and means for increasing and decreasing the pressure in the tubes in out-of-phase relationship. The means for generating pressure pulses comprises two cylinders 24 each containing a piston, the piston rods being connected together by a frame assembly 46 so as to move in unison. Air under pressure is admitted to the inner ends of the two cylinders alternately from a supply pipe 7, under the control of a solenoid actuated valve 8. The space enclosed at the outer end of the cylinders are connected through tubes 4, 6 to U-tubes 9a, 9b, 9c and 12a, 12b, 12c, containing water. Continuous reciprocation of the pistons is produced by a changeover switch 54 which is actuated by .adjustable contact members 51, 52 on the frame 46 and which effects reversal of the switch 8. The movement of the pistons causes alternate pressure and rarefaction pulsations in outlet tubes 4, 6 and the U- tubes. Finally the second leg of each U- tube is connected to a pair of mixer tubes 22, each of which is in the form of a double U-tube, so that air cannot be blown directly into the mixing compartments 20. As the pressure pulsations occur, liquid in the compartments 20 is alternately sucked up into and expelled from the tubes 22 and since the two tubes dipping into any one compartment work out of phase, there is no change in the general level. Bleed valves 11, 14 are provided to control the amplitude of the pulsations in the U-tubes 9, 12 and valves 23, 66 open to the atmosphere to permit equalization of the static pressures in the various branches of the system. The two contact operating members 51, 52 may be brought together or separated by a screw 53 and the setting of this determines the frequency of the pulsations.

Abstract: 697,894. Casks and barrels. ROTH, W., and KERN, A., [trading as FASSFABRIK DIENER & ROTH]. Jan. 15,1952 [Jan. 16, 1951], No. 1193/52. Class 21 For lining the inside of wooden barrels, particularly those for the transportation of beer and wine, a condensation product which is liquid or viscous at atmospheric temperature is uniformly applied to the inner surface of the barrel so as to form a layer which is highly resilient and which, after hardening, is impervious, relatively hard, and resistant to scratching. Thermoplastic resins such as polyvinyl chlorides, polyvinyl acetates, aldehydes, &c. are suitable. A multiple layer may be used, the lower layers of which consist of a protective mass having fungicidal and bactericidal properties, while the covering layers, which combine intimately with the foundation layers, are impervious to liquid and gas. The layer may be caused to permeate into the pores or spaces in the wood by means of superatmospheric pressure of approximately two to four atmospheres applied for a sufficiently long time. Drying of the layers may be accelerated by using hot air or infra-red radiation.

Filed: 1951-01-18
Abstract: 704,157. Spray carburetters. ORMAN, F. J. Jan. 18, 1951, No. 1358/51. Class 7(3) The supply of fuel is regulated by means of a tube A provided with slots A<2> on the engine side, the tube being raised to an extent depending on the area uncovered by a cylindrical throttle valve C whereby a proportionate slot area is exposed to an air intake B, and the effective slot area being variable by means of a second slotted tube A<1> rotatably mounted within the tube A. As shown, the tube A is fixed to a suction - actuated piston A<3> housed in the throttle valve C, and the tube A<1> is rotated by gears H. G<1>, G from a lever I. The tubes A, A<1> dip into a well E supplied with fuel by a pump or gravity through a filter O<1>; when the tubes are raised, a valve E<1> in the bottom of the well is opened. To provide gradual exposure of the slots A<2> on emergence from the well, the lip of a hole in a fuel supply block O has a cone-shaped projection V. The air intake B has a channel at its lowest point to direct the air flow around the tubes for starting and slow running, and two curved metal strips M in the channel together form a small choke passage. A piston sleeve A<4> attached to the tube A closes the air passage when the engine is inoperative. When the engine starts and the piston rises a ball valve prevents thte pistons from lowering quickly; slots in the valve seating allow an air bleed into the top of the piston to allow the piston to drop when stopping the engine. A piston L fixed to the bottom of the tube A has holes which pass fuel under normal throttle conditions; on rapid acceleration, a washer L<1> is forced against the top of the piston and closes the holes so that the piston pumps extra fuel into the air stream. N is a stop for the slowrunning position of the throttle.
