Title: Die casting method of manufacturing one-piece hollow article, such as metal "wood" head of golf club
Inventor: LEE HOU CHENG
IPC: B22D19/00
Filed: 1983-11-02
Abstract: The method comprises the steps of manufacturing a hollow core (4) by die casting e.g. aluminium, filling the hollow core (4) with a mixture of resin and sand, then heating the hollow core so as to solidify the mixture, die- casting further molten metal around the filled core and polishing the exterior of the casting. The resin is gasified, so that the sand can be loosened by tapping the article and then poured out through the hollow stem (41). <IMAGE>

Patent GB-2162691-A (GB)
Title: Miniature relay
Inventor: ELDRIDGE PETER GORDON
IPC: H01H50/18
Filed: 1984-08-02
Abstract: A miniature electromagnetic relay has a contact spring (13,14) movable by pivotally mounted armature (7) extending through the energising winding (6) and pivotally mounted at a position (8) nearer one pair (11B,12B) of pole faces at one end of the armature (7) than another pair (11A,12A) of pole faces at the other end of the armature (7). This enables a relatively large contact gap and contact-making force because the air gap of the nearer pair of pole faces (11B,12B) is smaller than that of the other pair (11A,12A). Relatively high currents e.g. 20 amps at 240 volts can be switched by a relay measuring only 50 millimetres long, 20 millimetres wide and 12 millimetres high. <IMAGE>

Title: Improvements relating to spark igniters for gas appliances
Inventor: SPRUCE FRANK
IPC: F23Q3/00
Filed: 1985-01-25
Abstract: The present specification discloses a spark igniter for use in a gas appliance. The assembly comprises a piezo electric device (9) mounted on a control spindle (5) of a gas control valve (1). The piezo electric device (9) is designed to grip the control spindle (5) solely in one direction of relative rotation corresponding to movement of the control spindle (5) to open the valve (1). From the valve fully closed position, the piezo electric device (9) is free to rotate with the control spindle (5) for part of the available spindle rotation, said device (9) engaging a stop (15) for the remainder of the available spindle rotation. During the remainder of this available spindle rotation, the control spindle primes the piezo electric device so that it fires shortly before the limit of said available spindle rotation is reached. Return rotation of the control spindle does not affect the piezo electric device (9) and the piezo electric device can only be fired after the control spindle has first been returned to the valve fully closed position. <IMAGE>

Patent GB-2186134-A (GB)
Title: Heating circuits with protective arrangements
Inventor: BAILEY ARTHUR RAYMOND
IPC: H02H5/04
Filed: 1986-02-01
Abstract: A heating circuit for an electric blanket comprises two heating elements 1 and 3. One element (1) has a coaxial overheat sensing winding 2 such that the insulation between the windings will drop significantly if the element overheats. This element 1 is bypassed by diode 8. The protection winding 2 is connected via a diode 4, a resistor 5, and thermal fuse 6, to the pole of the supply opposite to that which feeds the protected element 1. In the event of overheat in the protected element, current will flow through resistor 5. The resultant heating of the resistor is used to trip the thermal fuse 6. The time for fusing is virtually independent of the position of the overheat in the protected element. The basic circuit can be adapted to use two protected elements and also to give three heat settings by the use of additional components. <IMAGE>
