Patent GB-2455607-A (GB)
Title: Overvoltage Protection
Inventor: MULLIGAN DAVID R
IPC: G05F1/614
Filed: 2008-10-15
Abstract: An overvoltage protection system includes a control circuit 30 and a bank of independently switched resistors 32-38 that are switched into the circuit in combination to dissipate energy from a transient voltage preventing the voltage from rising to an unsafe level. Control circuit 30 can be a microcontroller but may include a binary counter 40 controlling resistor switches 42-48. Counter 40 is reset when the voltage exceeds an upper threshold, switching all resistors on, and counts when the voltage is below the lower threshold, thereby adjusting the combined resistance, until a final count is reached and all resistor switches 42-48 are off. Resistors 32-38 can have values in the ratio 2:1 and a delay element 66 can temporarily disable the counter outputs upon system initialisation. The protective system can be used in an automotive battery bus system to guard against voltage surges arising from events such as a load dump that can occur when jump-starting a vehicle or a battery is momentarily disconnected.

Title: Improvements in locking device for lubricator caps or the like
IPC: F16N11/02
Filed: 1922-04-11
Abstract: 192,967. Batchelor, H., and Abell, H. C. April 11, 1922. Locking nuts.-To lock the screwed - cap of a grease-cup or the like a stem 7 is mounted in the cup and has a finger 8 projecting outwardly approximately at rightangles thereto. The contact of a branch 9 of the stem 7 with stops on the cup a limits the angular movement of the finger 8 between the extreme limits 8x, 8Y. The length of the finger 8 is such that it always protrudes slightly over the circumference of the cup a. When the cap f is screwed on, the finger 8 takes up the position 8<y> so that the end thereof just presses against the screwed-thread on the cap. A smafll unscrewing force on the cap causes the end of the finger 8 to bite in the thread on the cap and oppose rotation. A deliberate unscrewing force on the cap, however, will bend the finger 8, and force it into the position 8<x>, and then unscrewing can proceed without resistance, but any consequent screwing on of the cap is resisted by the finger 8 unless a deliberate force is applied when the finger 8 is again forced into the position 8<y>.

Title: Improvements in and relating to electric switches
IPC: H01H1/32
Filed: 1953-04-16
Abstract: 730,116. Press-button retractive switches. GENERAL ELECTRIC CO. April 16, 1953 [April 26, 1952], No. 10418/53. Class 38 (5). An electric contact making and breaking device such as a push-button switch comprises an insulating body in two parts 1, 1a in which are mounted two pairs 9, 10 and 11, 12 of stationary spaced-apart contacts, each pair of contacts having their contacting surfaces in substantially the same plane, the two planes being parallel to one another; an actuating member 2 disposed between the contacts and movable in a plane normal to the planes of the contact surfaces, a slot 3 of non-rectangular parallelogram shape being provided through the actuating member 2 through which slot extend two bridging contact members 4, 5 spaced apart by a spring 6 and each of which has an arcuate portion 4c, 5c which has its centre of curvature approximately equidistant from either end of the bridging contact member so that when the actuating member 2 is moved by depression of a push-button 7 the bridging contact members are simultaneously separated at both ends of the bridging contact member from the stationary contacts irrespective of any misalignment of these contacts. The provision of the arcuate portions 4c, 5c in the contact bridging contact members and the non-rectangular shape of the slot 3 ensures that when a bridging contact member is operated by the actuating member 2, the contact between these two parts takes place in a point which is equidistant, the ends of the contact bridging member and thus there is no tendency for the bridging member to pivot about any point. The spring 6 which separates the contact bridging members 4, 5 also serves to provide a certain degree of lost-motion during operation of the switch. The retractive force is supplied by a spring 14.
