Abstract: 427,897. Hinges. CHENEY, C. W., Factory Road, Soho, Birmingham. Nov. 2, 1933, Nos. 30450/33 and 6072/34. [Class 65 (ii)] The parts 2, 9 of hinges and hasps for suit cases and the like are formed from sheet metal blanks with flanged edges 3, and are connected by a hinge pin 8 which engages pairs of lugs 5, 12 on the respective parts, the lugs joining up with the flange and extending from the edge thereof to a depth greater than that of the flange, and being connected for the greater part of their length by a hood or bridge 4 or 11 merging into the body of the member 2 or 9. The lugs and bridge of one member engage inside those of the other as shown, giving mutual support. A spring 16, Fig. 2, surrounding the pin and bearing against the undersides of the members 2, 9 may be provided. In a modification, Fig. 6, instead of the pin 8 bearing in apertures in both pairs of lugs 5, 12, it bears in the inner pair 12 only, and the outer lugs 5 have extensions 17 which are bent over to embrace the lugs 12 and bear at their ends on the pin 8. According to the second Provisional Specification, the lugs 12 in the form shown in Fig. 2, may be replaced by a barrel formed in the member 10 and partly cut away to accommodate the spring.

Title: Pneumatic pressure responsive device
IPC: G05D16/16
Filed: 1959-09-08
Abstract: 883,844. Fluid-pressure servomotor-control systems; valves. SPECIALTIES DEVELOPMENT CORPORATION. Sept. 8, 1959 [Nov. 6, 1958], No. 30591/59. Class 135. The control of a pressure actuated device, not shown, e.g. a valve regulating the operation of an air compressor, is effected by interconnected loose-ball valves 22, 39 under the influence of a diaphragm 34 subject to the pressure in an air reservoir via a port 32. Below a given reservoir pressure the parts assume the position shown, but when the given pressure is attained the diaphragm 34 is deflected to abut the valve 39; any further pressure increase causes a stem 28 to be depressed and after a small lost-motion to unseat the valve 22 so enabling pressure air from an inlet 16 to flow to the device by way of an outlet 17 and render the compressor ineffective. When the reservoir pressure falls the diaphragm 34 and stem 28 are lifted by a spring 40 and the valve 22 is reseated by its spring 26 whereupon the air in the device flows via outlet 17, a passage 37 in the stem 28 and the valve 39, after unseating it to a vent port 30; the compressor now recommences operation. The valve 22 is disposed in an apertured cage 24 and carried by a follower 25 supported on the spring 26; the valve 22 which is of stainless steel, e.g. co-operates with a seat formed of a disc of polyethylene terephthalate, e.g. and having an annular arcuate zone 41 against which the valve 22 is urged when in the closed position.

Title: Method and apparatus for stress-relieving stranded wire structures
IPC: C21D9/60
Filed: 1962-08-13
Abstract: In a method and apparatus for annealing a stranded and lubricated wire rope the latter is while moving heated by induction, possibly in a non-oxidizing atmosphere, to a temperature between 600  DEG F. and 1100  DEG F. and is then cooled to below the flash point of the lubricant while surrounded by lubricant, by non-oxidizing medium or by steam.  As illustrated, the rope passes through seal 24 into tube 12 wherein it is heated by coil 22, and then through steel tube 14 surrounded by water jacket 16. Tube 14 may be supplied with lubricant by pipe 33; alternatively it may be filled with nitrogen or other inert gas, or where the product is not required to be lubricated water may be delivered by pipe 28 in such amounts that it is converted to steam on contacting the hot rope thereby cleaning the latter.

Title: A safety circuit arrangement for the welding by means of alternating current
IPC: F27D99/00
Filed: 1952-12-08
Abstract: 714,238. Control systems for welding arcs. LICENTIA PATENT-VERWALTUNGS-GES. Dec. 8, 1952 [Dec. 17, 1951], No. 31061/52. Class 38(4) To ensure automatic reduction of the voltage across a welding circuit E during non-welding periods, the circuit is supplied from a transformer F having direct current pre-magnetization windings, such as the phase- and frequency-changing transformer described in Specification 714,146, and a relay R1, responsive to conditions in the welding circuit, is arranged to reduce the excitation of the premagnetization windings during no-load running. As shown in Fig. 1, a resistor W in series with a D.C. excitation source B is short-circuited by the contacts of relay R1 during welding, this relay winding then being de-energized on account of the open contacts of a further relay R2 energized by the melting current, over a transformer S. Upon cessation of flow of welding current relay R2 completes the entergizing circuit of relay R1, which opens its contacts and allows the resistor W to become effective to reduce the D.C. excitation of the transformer F. In modified arrangements relay R2 is dispensed with and relay R1 is controlled directly by the current transformer S. To increase the speed of response of the system further contacts may be provided in the relay system to load the transformer during non-welding periods by an inductive reactor. Relay R1 may effect control by opening or closing the circuit of a second pre-magnetization winding, instead of by switching the resistor W. A magnetic amplifier or discharge tube, controlled from the welding circuit and controlling the pre-magnetization of the transformer F may replace the relay R1.

Abstract: 629,801. Ventilators. AKTIEBOLAGET SVENSKA FLAKTFABRIKEN Dec. 3, 1947, No. 31972. Convention date, Oct. 8, 1945. [Class 137] A ventilator for a vehicle comprises two concentric air passages, a fan which causes air to flow into the vehicle through one passage and out of the vehicle through the other passage, and an adjustable valve member which isolates the passages from one another, or varies the extent of communication between them whereby varying proportions of spent air and fresh air are mixed and introduced into the vehicle. The ventilator is shown as applied to the vehicle roof 3, the mantle 1, which is insulated at 4, having a flange 2 for securing thereto. Bars 5 extending vertically from the mantle 1 support an annular baffle 6 and two caps 7, 8 having rain-excluding rims. A rod 9 depends vertically from the cap 8, a spider 10 being slidable on the rod 9 under the control of a spring 11 and lever mechanism 12, 13, 14 operated either manually or by a servo-motor 15. A hollow, preferably conical, valve member 16 is carried by the spider 10, and is prevented from rotating by fins 17 engaging in guides 18. The bottom of the member 16 is flared so that when the valve is fully raised, the fresh air inlet passage is closed, and when it is fully lowered the amount of spent air recirculated with the fresh air is reduced to a minimum. The fan is driven by a motor 20 and consists of an outer part 32 with upstanding impeller blades 19 and radial arms 31 which connect the part 32 to the hub 33 and are themselves formed as fan blades to produce a flow of spent air upwardly through the centre passage and outwardly under the cap 8. The member 16 may be fixed and the lower part provided with adjustable openings, and the fresh air inlet passage may be the central passage. The ventilator may be combined in known manner with a filter, heatexchangers and humidifying devices.
