Title: Improvements in and relating to plug and socket connectors
IPC: H01R13/41
Filed: 1961-11-27
Abstract: 956,993. Resilient bush mountings. R. F. OXLEY. Jan. 25, 1963 [Nov. 27, 1961], No. 42371/61. Heading F2S. [Also in Division H2] A fitting for attachment in an aperture comprises a bush of resiliently deformable material with a circumferential groove on its external surface to receive the edges of the aperture with a limited degree of lateral movement, and a pin (formed as a plug or socket contact (see Division H2)) which can be forced into the bore of the bush and retained therein. Fig. 3 shows a bush 31 of P.T.F.E. having a cylindrical part 33 larger than aperture 34 in a member A, a tapered groove 35 the thicker end of which has a diameter less than aperture 34 and a tapered part 36 the thick end being larger than the aperture but able to be forced through. The pin 32 is forced into the bore 37 of the bush, which is first passed through the aperture, so that the enlargement 41 swells the end part 36 of the bush so that it no longer can pass through the aperture, the tapered groove being deformed into a cylindrical form (Fig. 4). In Figs. 1, 2 (not shown), a number of these fittings are attached to plates having apertures to form multi-core cable plugs and sockets. It is not necessary for both the plug and socket to have pins having freedom of lateral movement (Fig. 5, not shown), and to prevent relative movement between the bodies a few pairs of both pins may be rigidly fixed.

Title: Method of and apparatus for rolling out sections in one pass, and a rolling mill for carrying out the method
IPC: B21B45/00
Filed: 1962-11-09
Abstract: 980,362. Rolling; winding and reeling. DER VON MOOS SCHEN EISENWERKE A. G. Nov. 9, 1962 [Nov. 25, 1961], No. 42484/62. Headings B3E and B3M. A method of rolling out sections in a single pass is characterized in that the temperature of the stock is regulated in dependence of the filling of the pass groove. If the pass groove becomes underfilled, as measured by a radiation pyrometer 10, the temperature of the incoming stock is reduced, while for overfilling, the temperature is increased in dependence on the reduction in roll speed or overloading of the driving motors. The rolls of stands 2a and 2b are connected to the secondary winding of a transformer 6 so that the metal stock 4 acts as a conducting path. Movement of stand 2a by a handle 8a in a screw 8 varies the resistance of the current path and hence the heating of the stock. Before rolling, the stock passes a device 14 which straightens the stock and frees it from tension. The device is mounted on gently inclined rails 17 so that any tension in the stocks pulls the device 14 upwardly. This causes the drive from a motor 20 to the straightening rolls to be speeded up, thus cancelling the tension. This is effected by a roller which runs up an inclined fixed surface to rotate a lever arm and thus vary the effective diameter of an adjustable pulley which transmits the drive from the motor. Instead of the coilers of Fig. 1, a store 40, Fig. 5, and a stacking site 55 may be provided, and the store 40 may be replaced, if desired, by an electric, gas or oil-fired continuous furnace 40a for preheating the stock. Shifters, Fig. 6, are used in conjunction with the stacking site, each shifter having pivoted levers 52 and 54 which move the stock from the rolling line down an inclined surface 53 to the site 55. Where the rolled stock is not of flat form the conventional coiler may be replaced by one having a drum 31, Fig. 3, consisting of a cylindrical portion 31a and a conical portion 31b, the drum being driven around a fixed shaft 32 by an internally meshing pinion 34. A disc 38, having extending fingers 38a, is freely mounted on the shaft 32 at an angle to its axis, and is carried round by the drum so that the fingers oscillate in slots 31c to continually push stock towards the portion 31b of the drum.

Title: Improvements in hydraulic braking systems for vehicles
Inventor: YARDLEY ALFRED
IPC: B60T11/28
Filed: 1962-11-13
Abstract: 1,059,735. Hydraulic braking systems. GIRLING Ltd. Nov. 7, 1963 [Nov. 13, 1962; Feb. 5, 1963], Nos. 42790/62 and 4588/63. Heading F2F. In an hydraulic braking system wherein a master cylinder 10 pressurizes an hydraulic line leading to slave cylinders in calipers 13 for applying brake pads to discs 14, a device is connected to the hydraulic line which includes a spring-loaded piston for accommodating fluid displaced from the slave cylinders when the brakes are in the off position, caused by knock-back of the slave cylinder pistons, and for returning such displaced fluid when the knock-back conditions cease. In one embodiment, Fig. 1, the device comprises an auxiliary cylinder 18 in which a sleeve 22 is slidable against the loading of a spring 28. An aperture 23 in the rear portion of the sleeve is normally closed by a ball 24 acted on by a spring 25 anchored on a ring 26 located in the forward end of the sleeve. Fluid displaced by knock-back of the slave cylinder pistons moves sleeve 22 rearwardly, compressing the spring 28 which returns the sleeve when knock-back ceases. During normal brake operation the ball 24 operates as a one-way valve in the forward direction of flow from the master cylinder, and, owing to the provision of a slot 27 in the sleeve 22, the latter acts as a one-way valve permitting return of fluid to the master cylinder after the sleeve has been displaced rearwardly a sufficient distance. Working clearance between the sleeve 22 and the cylinder 18 allows fluid to pass slowly between the mutually sliding surfaces so that spring 28 can return the sleeve to its forward position following brake release. In a second embodiment, Fig. 2, the auxiliary cylinder is disposed between the relief port 38 of the master cylinder and the reservoir 36 and comprises a stepped bore 37 in which is slidable a piston 39 loaded by a spring 41 to a lower position. Knockback causes fluid to be displaced through the port 38 to move piston 39 upwardly, compressing spring 41 which returns the piston 39 when knock-back ceases. High temperature conditions or excessive knock-back moves piston 39 sufficiently to permit fluid to pass into the larger diameter part of the bore and thence to the reservoir. The usual replenishment port 43 is provided to maintain the system filled with fluid. During brake operation port 38 is cut off from the system by the piston 31, 33 of the master cylinder.

Title: Improvements in or relating to the conversion of non-magnetic iron oxide ores to magnetite
IPC: F42B19/00
Filed: 1964-10-26
Abstract: Non-magnetic, iron oxide ores are converted to magnetic magnetite for concentration by magnetic separation by introducing the ground ore into a reaction zone with a reducing gas under sufficient pressure to blow fine ore particles directly through the reaction zone to effect magnetic conversion by flash roasting thereof whilst the remaining coarse particles pass through at a slower rate to effect magnetic conversion by roasting.  The ore may be haematite and may be ground to minus 65 mesh.  The reducing gas may be produced by combustion of a hydrocarbon gas, e.g. methane, or a solid fuel reformed gas, e.g. producer gas within the reaction zone.  The spent reducing gases may be separated from the converted ore and used as an aid in heating the reaction zone and to preheat the ore, and a portion may be cooled and used to cool the converted are particles. In the Fig. ground ore is fed into and dried in countercurrent cyclone 15 by contact with hot spent reducing gases from conduit 22. The dried ore is further heated by hot, spent reducing gases in cyclone 18 and fed into the interior tube 11 of a concentric double tube kiln rotated by motor 14.  A mixture of air preheated hydrocarbon gas or solid fuel reformed gas and spent reducing gas through pipe 38 is admitted into tube 11 so that ore particles of minus 200 mesh are blown rapidly through tube 11.  The magnetite is separated from hot, spent reducing gases in dust collector 23 and fed into cyclone 25 where the waste heat is recovered in prehating fresh reducing gas admitted through valve 35 and spent reducing gas from cyclone 23 which has been cooled by heat exchange with air in heat exchanger 28 and scrubbed in scrubbing tower 33 to remove entrained fines. The preheated gas mixture is conveyed through pipe 36, mixed with air from blower 39 and fed into the tube 11 wherein partial combustion produces the hot, reducing gases.  The minor portion of the hot, spent reducing gases from cyclone 23 and the hot air from heat exchanger 28 are passed into annulus 13 of the kiln through pipes 30 and 31 respectively, which serves to insulate the reaction zone and maintain the temperature of the kiln by further burning of the spent reducing gases.  From annulus 13, the hot gas mixture passes through pipe 21 to cyclones 18 and 15 to dry and preheat the ore.

Abstract: 1438575 Conveyers REGIE NATIONALE DES USINES RENAULT 17 Sept 1973 [22 Sept 1972] 43588/73 Heading B8A [Also in Divisions F4 and B3] Carriers 6, which as shown are casting ladles for centrifugal casting of cylinder liners, are each conveyed by the action of four arms 5a, 5b, 5c and 5d, which carry rollers 7 running in respective tracks 20a-20d of a rotating drive member 1. The roller 7 which is associated with the track 20d, has an associated braking mechanism, so that the roller can be locked to the track 20d thus providing the driving transmission between the member 1 and the associated carrier. Also the track 20d moves faster that the tracks 20a-20c. This is brought about by the drive being direct to the track 20d, but through an epicyclic gear 18 to the tracks 20a- 20c. The brake to the roller 7 is applied via a cam surface 34 on the machine frame to a cam roller 33 (Fig. 3), on a lever 31 which is operatively connected with brake linings 25. A cam surface 35, similar to the surface 34, is carried by each arm 5d. This co-operates with the cam 33 on the roller 7 of the arm 5d of the adjacent carriage. By this means, the brakes are released when the carriages approach too closely. In a modification (Fig. 4, not shown), the circular tracks 20a-20d are replaced by tracks carried by an endless belt (38b), driven by a toothed drive roller (39). The belt is supported by members (40) having wearing strips of a low friction coefficient of synthetic material.
