Abstract: A reclaiming device for orange gold foils in a hot stamping machine comprises a swing stand (14) which is pivotally mounted on a trunk (11) and on which are rotatably mounted a roller (12) for raw orange gold foils and a reclaiming roller (13). The swing stand (14) is caused to pivot about an arc by reciprocating movement of a rocker lever (15) and movement in one direction causes a sprocket (24) mounted on the reclaiming roller (13) to drive a chain (17) which causes a sprocket (25) to rotate. The sprocket (25) is provided on a process controller (16) rotatably mounted on a stationary axle (26) fixed to the trunk (11) and rotation of the sprocket (25), and hence the process controller (16), causes a swing rod (28) to pivot in an opposite direction to that of the swing stand (14) until it abuts a stop on an adjuster (19). Further pivoting movement of the swing stand (14) is effective to cause relative rotation to take place between the swing rod (20) and the process controller (16), and movement of the swing stand in the opposite direction is effective to cause the process controller (16) to drive the reclaiming roller (13), via the chain (17) and sprocket (24), to wind on foils from the roller (12) which foils are first passed over guide rollers (20, 21).   <IMAGE>

Title: A metering valve for a liquid charged with a propellent liquid of liquified gas and usable in the upsidedown position
Inventor: BRUNET MICHEL
IPC: B65D83/14
Filed: 1988-05-12
Abstract: When the valve is turned upsidedown, the metering chamber (16) is filled with liquid via a gap (2a) between a gasket (2) and the valve rod (9). In order to fill the chamber as quickly as possible, the gas leaving the chamber must be prevented from opposing the inward flow of liquid. To do this, the gas is evacuated via a central channel (21) in the valve rod; as liquid passes down via opening (8) and around a thinner portion (14) of valve rod (9,) via annular gap (2a), gas exits via radial passages (21b), passage (21) and opening (21a) to escape via orifice (1b). <IMAGE>
Patent GB-2219979-A (GB)
Title: Vehicle coupling and towing bracket
Inventor: ROSE DERRICK B
IPC: B60D1/44
Filed: 1988-06-27
Abstract: A towing vehicle is fitted with a bracket which consists of a tube 10 curved in the form of an arc. A trailer or caravan is connected to this bracket by means of a coupling head 12 which is fitted with opposing pairs of swiveling rollers 13. The hinged jaws 12, 14 that carry these rollers are clamped together by means of a bolt 17 sandwiching the tube of the bracket between the rollers. Hence whilst the trailer or caravan is being towed by the vehicle in a straight line there is an inherent resistance to pivot at the point of coupling about a vertical axis. However, lateral movement is unrestricted when a change of direction is required as the rollers will travel along the tube of the bracket. Each pair of opposing rollers is individually pivoted about a vortical axis to accommodate the curve of tube 10. <IMAGE>
Patent GB-885591-A (GB)
Abstract: 885,591. Drafting-mechanism. MACKIE & SONS Ltd., JAMES. June 3, 1960 [June 4, 1959], No. 19159/59. Class 120(2) In a mounting for a pressing-roller 2, cooperating with a drafting roller 1 for drawing fibres, the pressing-roller turns on an axle 4 mounted on a swinging bracket 5 controlled by a handle 8 turning about a fixed pivot 6; movement of the handle in one direction produces a cam action to load a spring 17 so as to transmit pressure to bracket 5 and thus to press roller 2 against roller 1, while movement of the handle in the other direction relieves the spring-pressure and causes a part movable with the handle to engage the bracket so as to lift roller 2 away from roller 1. In Fig. I, the cam action is produced by a roller 21 on a part 7 secured to the handle and mounted to rotate on pivot 6; with the parts in the inoperative position shown, roller 21 rests in a latching position between an abutment 23 of bracket 5 and the tip 22 of a lever 10 pivoted on a bracket 9 fixed to the pivot. When the handle is lowered, roller 21 having been freed by first raising the handle and manually rocking lever 10, part 7 moves clockwise and allows abutment 23 and bracket 5 to move so that roller 2 lightly rests on roller 1, roller 21 engages the part 22a of lever 10 and an adjustable pin 15 engages spring 17. Further movement of the handle causes roller 21 to move beneath lever 10 to rock it to load spring 17 to press roller 2 into operative engagement. In another form, Fig. 4, the handle is fast with a cam 31 which in the position shown loads spring 17 to bring arm 5 down to a position where roller 2 is in operative engagement. When the handle is raised to an intermediate position, the spring is relieved from pressure; with further raising of the handle, a part 33 of the cam raises the arm 5 to lift the roller 2 away from roller 1, a recess 34 forming a latching-position. The leaf-spring 17 may be replaced by a compressionspring.

Title: Circuit protection device
Inventor: GRAHAM ANDREW C
IPC: H01L21/822
Filed: 1990-07-18
Abstract: The invention provides for a circuit protection device in which a threshold voltage is selectively raised above the power supply voltage (VDD) by the inclusion of level shifter (20) connected between the power supply (VDD) and a discharge reference rail (15). The level shifter (20) conducts when a voltage applied to the rail (15) is greater than the power supply voltage (VDD) by an amount equal to the sum of the various diode voltage drops across the level shifter (20). The various input pads of an integrated circuit including FETs to be protected are connected to an anode of an associated diode (D1, D3) wherein the cathode of the associated diode (D1, D3) is connected to the discharge reference rail (15), rather than directly to VDD as in the prior art. The anode of the diode (D1) is also connected to the circuit to be protected. Thus, when a voltage applied to the input pad is approximately one diode drop above the voltage on the discharge reference rail (15), the voltage at the input pad will be shunted to the power supply voltage (VDD) generator through the level shifter (20.) The level shifter (20) may include conventional diodes or zener diodes. Diode D5 serves to maintain reference rail (15) at one diode drop below VDD during normal operation. The inclusion of the level shifter 20 permits the input voltages at nodes 1,2 to rise significantly above VDD for performing various test functions on the integrated circuit. <IMAGE>
