Title: Improvements in or relating to hinged door operating means
IPC: E05F15/04
Filed: 1952-02-27
Abstract: 722,335. Door-operating apparatus. SCOTT, L. W. Feb. 27, 1953 [Feb. 27, 1952], No. 6191/52. Class 66(1). [Also in Group XXVIII] Double hinged doors for mines in which the air pressure is greater on one side of the doors than on the other are opened simultaneously against the air pressure by power-ram means, the pressure of the ram being automatically reduced after the initial resistance of the airpressure has been overcome, and the pressure on the ram being relieved to allow the doors to be closed simultaneously by weight means. In the arrangement shown in plan, arms 17 fixed to the hinge spindles 3 of the doors 1 are connected by links 15 to a crosshead 11 secured to the piston-rod 9 of a compressed-air ram 8. Links 100 connect the arms 17 with the doors 1 to relieve the strain on the hinge spindles. Air is admitted to the front end of the cylinder 8 through a valve 7 controlled by a handle 47. A by-pass 85, which may have an adjustable valve 86, reduces the effective pressure on the piston after it has covered a part of its stroke, and a release valve 87 determines the cushioning pressure at the end of the stroke ; a cushioning spring may be used. When the valve 7 is restored, to release air from the cylinder, the doors are closed by a weight 53 connected to them by a cord 60 ; the exhaust from the cylinder may be regulated by a valve. The parts of the mechanism projecting beyond the doors are accommodated in a recess over the doors with an end wall 62. In a modification, the ram opens the doors by a pushing action; in this case the cylinder 8 may pass through the wall 62. The cylinder is preferably formed of a steel tube with separate end-caps formed with square flanges and held together by tension rods 66, which also secure the ram to its fixing means 68, 69, the caps thus being readily interchanged to reverse the ram; each cap has a hole to receive the inlet pipe or the release valve which are thus also interchangeable to reverse the direction of action of the engine. According to the Provisional Specification, instead of using a by-pass passage a reducing valve is placed in the main inlet pipe and is operated to restrict the air flow by air from a port in the cylinder which is uncovered by the piston during its stroke ; several such ports may be provided, the pipe to the reducing valve being connected to the selected one while the others are closed by plugs, or the pipe being fixed and all the ports connected to it, those not required being shut off by plugs. A separate closing weight may be provided for each door.

[Classes 70 and 87 (ii).] Strips of rubber are formed from compounded latex or the like by extruding a number of thin strips into a coagulating bath and pressing the strips together to form a thicker strip. As shown, latex is extruded by gas pressure through slits 14 in the side of a closed tank 10 into a bath 16 of coagulant such as acetic acid or acetone. The strips are supported near the slits by rollers 17 and after passing through the bath are pressed together by rollers 18. The slits may be of different lengths, as shown in Fig. 2, to form strips of different cross sectional profile, e.g. as shown in Fig. 3, for tyre-tread stock.

Title: Process of separating an azeotropic mixture
Inventor: BINNING ROBERT C
IPC: B21C37/29
Filed: 1958-02-18
Abstract: Azeotropic mixtures are separated into their components by submitting the mixture to dialysis using a membrane of plastic material, and separating the components from one or both of the liquids obtained by distillation, leaving a fraction which approximates to the original azeotropic mixture, which is re-cycled.  The plastic membrane selected is hydrophyllic or hydrophobic in accordance with the nature of the liquid component to permeate through it.  The following are specified (1) hydrophyllic, cellulose acetate, regenerated cellulose, polyacrylonitrile, hydrolysed P.V.A., nylon; hydrophobic, the higher esters or ethers of cellulose, polyethylene and polystyrene.  The permeation step may be effected with the feed liquid under pressure and at elevated temperature, and the permeate removed with vapours (e.g. steam or butane) and at low pressure.  In examples, the process is applied to azeotropic mixtures of benzene and methanol, alcohol and water, and CS2 and acetone.

Abstract: 569,374. Brakes. BUDD WHEEL CO. April 7, 1943, No. 5555. Convention date, March 19, 1942. [Class 103 (i)] In a brake for railway vehicles, of the kind comprising a pair of shoes arranged to be applied to the opposite sides of a wheel, application is effected by a fluid-pressure cylinder which is mounted for floating movement in a support which may be a frame member of the vehicle, the piston and cylinder each engaging a lever carrying one of the shoes. A railway truck of the type described in Specification 556,295, [Group XXXII], comprises longitudinal and transverse members 10 ... 13, wheels 16 between the members 10, 11 at each end and a vertical pivot near the longitudinal centre for connection to a transverse bolster of the body underframe. Levers 24, 25 each carrying a brake shoe 22, 23 for application to rings 18, 19 on the wheel 16 are operated by a piston and cylinder device, the cylinder 32 of which is slidably mounted in the frame member 10 by means of an extension 31. This extension also passes through the end of lever 24 which it engages by a nut 39. The end 45 of the piston rod abuts on the end of the lever 25. Equalized pressure is thus applied to the shoes and the cylinder and piston can be readily removed by unscrewing the nut 39. Return springs 51, 52 are attached to the levers. Manual operation of the brake may be effected by an arm 54 on a shaft 53 carrying a second arm 55 connected by a slotted link 57 to toggle links 59, 60 pivoted to the levers.

Title: Arrangement for changing-over the speaking direction in two-way loud speaker telephone systems

Filed: 1945-03-08
Abstract: 596,662. Loud speaking systems. AUTOPHON AKT.-GES. March 8, 1945, No. 5807. Convention date, Dec. 4, 1942. [Class 40 (iv)] In a system in which each subscriber is provided with a one-way amplifier, the speaking direction can be changed at will by either subscriber dialling 1. In the called subscriber's apparatus, Fig. 1, a call having been set up by means unspecified, relay E remains operated to switch in the amplifier V irrespective of the polarity of the D.C. current received from the centre tap of the coil Dr sent over the earth phantom from transformer Tr, Fig. 2, at the exchange via a<1>, b'. If negative polarity is received relay U operates to switch the amplifier V to the " receive " condition and indicator lamp SZ short circuited by a rectifier element does not glow. If positive polarity is received, relay U is short-circuited and switches the amplifier V to the " transmit " condition and indicator lamp SZ glows. At the same time the opposite polarities are sent out over wires a<2>, b<2> to the other subscriber to effect the appropriate changes in his amplifier. The polarities sent out at the exchange are dependent on the position of the stepping switch S, through whose coil successive impulses cause the reversal of the outgoing polarities to the subscribers. The impulses are given by the momentary falling back of relays J or Y in the subscribers' phantom circuits when one or other of the subscribers dials 1. On completion of the call slow release relay II falls back to ensure that the final position of switch S is such as to put the subscriber's amplifier into the " receive " condition.
