Abstract: 1,206,302. Testing electricity meters. L. CREMER, H. CREMER and W. CREMER [trading as ZERA ELEKTRISCHE PRUFGERATE CREMER & CO. ]. Feb.15, 1968 [Feb.17, 1967], No.7472/68. Heading G1U. In testing an electricity meter of the rotating disc type in situ, a testing apparatus forming a constant load is connected to the supply lines behind the meter and the time taken for the disc of the meter to complete a predetermined number of revolutions is compared with a reference time to indicate the meter error. The reference time is calculated from the value of the constant load and takes into account the meter data. In the testing apparatus shown, the output of a multiplier 1 is a voltage representing the power consumed by the apparatus. This voltage is compared with a reference voltage 3, the difference being fed through a voltage divider 7 and amplifier 8 to control a variable auxiliary load 5 which is added to a time voltage dependent load 11 to provide the desired constant load. A unit 12 indicates when the time voltage falls outside predetermined limits. The time is measured by a stop watch or a mechanical or electronic device used in conjunction with a computer to determine the meter error. The actual time load is disconnected during the test by fuses or circuit breakers 20, 21, Fig.1 (not shown). The single phase apparatus shown may be used to test a meter in a polyphase system by switching the apparatus sequentially from one phase to another.

Title: Improvements in or relating to electric snap switches
IPC: H01C10/36
Filed: 1941-06-20
Abstract: 543,355. Snap action switches. IGRANIC ELECTRIC CO., Ltd. June 20, 1941, No. 7804. Convention date June 20, 1940. [Class 38 (v)] A base or casing is provided with vertically, spaced and aligned apertures, with an integral part of the casing between them, to serve as pivot bearings for lugs extending from a switch actuating element. In the example, a snap-action switch of flat construction, suitable for combining with a radio rheostat &c., comprises a base 20, in which is pivoted an apertured carrier 38 for contacts 41 adapted to bridge fixed terminal contacts 44 and spring contact arms 49. The carrier pivots on a pin 39 integral with the base and is held thereon by an actuating member 55 comprising a base part 55a with two upstanding integral arm portions 55d, 55e one of which has integral vertically spaced lugs 55f, 55g bent to extend at the same angle to both of the arms. These lugs rest in suitable apertures in the wall of the base 20 so that an arm 62, Fig. 5, on the rheostat may, by striking one or other of the arms 55d, 55e cause it to assume one or other of two limiting angular positions during a small movement of the rheostat arm, while being located vertically. A compression spring 36 bears at one end in a hole 55c of the actuator and at the other on a projection 38c in the aperture of the contact carrier 38. Thus the movement of the actuator snaps the carrier over from one side to the other. The carrier 38 may have a single bridging contact 41 as shown to effect a simple make and break, and by moving the contact 41 to an alternative position the action of the switch may be reversed, or by using more moving and fixed contacts two way or double switching may be effected. The metal cover 30 of the rheostat forms the top of the casing 20 and may have conical depressions 30d on opposite sides of the spring 36 to effect an earthing of the spring in each extreme position of the switch parts. Specifications 397,619 and 439,028 are referred to.

Abstract: 1344232 Friction clutches AISIN SEIKI KK 21 Feb 1972 [23 Feb 1971] 7863/72 Heading F2C  A friction clutch having a driven plate 13 clamped between a flywheel 11 and a presser plate 14 under the influence of a diaphragm spring 17 has an elastic and deformable member 34 which urges the driven plate 13 towards its disengaged position and is always strained to its limit of elastic deformation in the engaged condition so that wear of the friction facings causes plastic deformation, after which the member 34 (in particular the tongues 35 of the member 34) still has sufficient elasticity to move the driven plate 13 clear of flywheel 11 on disengagement. The aid to disengagement thus operates irrespective of wear. In a further embodiment a member is attached to the hub 30a of the plate 13 and has tongues engaging a portion of the driven shaft 15.
