Patent GB-929072-A (GB)
Title: Improvements in or relating to welding composite metallic strip material
IPC: B23K11/04
Filed: 1961-02-24
Abstract: 929,072. Welding by pressure. VANDERVELL PRODUCTS Ltd. Feb. 16, 1962 [Feb. 24, 1961], No. 6918/61. Class 83 (4). In electrically butt welding the edges of pieces of ferrous strip having a non-ferrous metal surface layer the pieces are arranged such that when the non-ferrous metal melts on application of welding current it is substantially removed from the weld locality by gravity. In welding pieces of steel coated with leaded bronze a fixed copper jaw holds one piece and a movable jaw holds the other with the steel uppermost, A.C. current is supplied between the jaws and as the abutting edges melt the moving jaw is advanced. The non-ferrous layer is melted and falls from the steel and any lead is volatilized. A blast of compressed air or hot or cold inert gas may assist removal. When the non- ferrous metal is removed from the weld area the current is cut off and the moving jaw is advanced to force the cleaned steel edges together to form weld. The coating may comprise copper based bearing alloy containing 3-30% lead and 0-15% tin.

Title: Improvements in and relating to means for preventing skidding of vehicle wheels
IPC: B60T8/42
Filed: 1968-02-15
Abstract: 1,203,731. Anti-skid control systems. AUTOMOTIVE PRODUCTS CO. Ltd. 28 Jan., 1969 [15 Feb., 1968], No. 7478/68. Heading F2F. In an anti-look braking system, brake pressure is released on sensing of wheel skid, the response being rapid to provide braking control such that the wheel speed fluctuates to a relatively small extent about the speed for optimum braking. As shown, a master cylinder 10 is connected via a valve 13 to a brake cylinder 12, the valve ball 19 being normally held off its seat by a spring 28. A servo 23 is divided by a diaphargm 25 into two chambers 26, 27, chamber 27 being connected to a low pressure source and chamber 26 to either a high pressure source, e.g. atmosphere via conduit 58 or a low pressure source, e.g. vacuum via conduit 59, via a control valve 32. On detection of a wheel skid, a switch 56 is closed to energize a solenoid 55 to actuate a spool valve 35 which in turn causes a valve system 36, 37, 38, 44 to connect chamber 26 to atmosphere, and thus close valve ball 19 to release brake pressure. When switch 56 is opened again, chamber 26 is connected to vacuum and valve ball 19 is again opened. A chamber 61, 62 and a restriction 63, 64 are provided in the atmosphere and vacuum conduits respectively such that when chamber 26 is connected to either atmosphere or vacuum, the initial response is very rapid followed by a relatively slow build-up or release of pressure. Such a chamber and restriction may be provided in only one of the atmosphere or vacuum conduits. The skid sensor, Fig. 2 (not shown), comprises a bevel gear driven at a speed proportional to the vehicle speed and a coaxial bevel gear driven at a speed proportional to the wheel speed, the arrangement being such that when the vehicle speed exceeds the wheel speed, the switch 56 is closed. The system may be of the hydrostatic type or of the continuous flow of pressure liquid or air type in which case the valve 13 is replaced by a device which shuts off the brake cylinders 12 from the pressure source and connects them to an exhaust.
