Title: Device for the measurement of deformations in a solid body
IPC: G01N3/14
Filed: 1972-04-24
Abstract: 1323848 Extensometers and compression testers COMPAGNIE POUR L'ETUDE & LA REALISATION DE COMBUSTIBLES ATOMIQUES 24 April 1972 [23 April 1971] 18832/72 Heading G1S A known extensometer, Fig. 1, having a weighted lever 15 pulling down on movable parts 4, 14 and the test piece 10 connected to a fixed support 3, is enclosed by protecting bellows 7, 8 filled with gas or liquid through a pipe 6 and holes 5. These bellows when deformed however act against the weighted lever with forces F1, F2 which are compensated for in Fig. 3 by a solenoid 30 attracting a magnetic core 24 with a variable force equivalent but opposite to F1 plus F2. The solenoid is supplied with variable current via a potentiometer 38 having a contact 35 whose position varies with the extension of the test piece and the variation of the forces F1, F2. In Fig. 4 a vessel 41 suspended from the lever is supplied with water or mercury via a syphon tube 44 so that the weight in the vessel increases or decreases linearly with the elongation or contraction of the test piece and thus compensates for F1 and F2. In Fig. 5 a container 45 holding liquid 50 of weight P1 and having a hole 48 is suspended in liquid in a vessel 46 providing an upthrust of P2 on the container. As the lever end 15b moves downwardly with extension of the test piece, liquid flows from 46 through the hole 48 into the container 45 decreasing the distance h. The thrust P2 and the depth H however remain constant but P1 increases linearly and consequently so does force F3 which is equal to P2-P1. Thus it is possible to choose the dimensions and liquid to compensate automatically for increases in the forces F1 and F2. In Fig. 6 (not shown) the hydraulic compensator of Fig. 5 is applied to a compression testing apparatus.

Title: Battery charging devices
IPC: H02J7/14
Filed: 1975-05-06
Abstract: 1457248 Automatic voltage control  NIPPONDENSO CO Ltd 6 May 1975 [6 May 1974] 18862/75 Heading G3R [Also in Division H2] The electrical generating system of a road vehicle, which comprises an alternator of which the field winding is controlled to control the output of the alternator, is modified in that the lamp normally used for indicating whether or not the battery is being charged is also used to indicate a fault - such as a disconnection - occurring in the system. A road vehicle electrical system comprises an alternator 1, the field winding 12 of which is controlled by a regulator 8 which includes a pair of transistors 405, 406. Closure of an ignition switch 6 causes illumination of the charge indicating lamp 51 by the potential of the battery 7 with the alternator stationary. The potential of the battery 7 is applied to the field winding 12 by way of indicating lamp 51 whereupon the alternator 1 develops an output which thereupon energizes the field winding 12 by way of a rectifier 31 and causes the lamp 51 to be extinguished, the battery being charged from the alternator main output terminal 23, the alternator output being regulated by the regulator 8 under the overiding control of a transistor 404 in a voltage detecting circuit 9 connected to a potential divider 401,402,412,403 across the battery 7. Should say, a disconnection occur between the battery terminal 71 and the input terminal 411 of the potential divider 401, 402, 412, 403, the field 12 will be energized to produce an excessive voltage at terminal 31 of the alternator. This causes conduction of transistors 422, 423 in a protection circuit 42. Conduction of transistor 422 causes conduction of transistors 404, 57. Conduction of transistor 404 blocks transistors 405, 405 whereupon the voltage at terminal 31 falls and conduction of transistor 57 causes illumination of the lamp 51 from terminal 31  by way of a diode 53. Fall of voltage at terminal 31 renders transistors 422, 423 non-conductive and hence transistors 404, 57 and the cycle repeats. Similar operation occurs should the battery fail to receive charging current. In other embodiments relays or reed switches may be used instead of transistors.
