Title: Electromagnetic relays
IPC: H01H50/04
Filed: 1973-08-18
Abstract: 1469111 Electromagnetic relays LUCAS ELECTRICAL CO Ltd 25 June 1974 [18 Aug 1973] 39175/73 Heading H1N An electromagnetic relay comprises electrical terminals 13, (14), 15 extending through and lying in contact with the inner face of an insulating base 11 and a frame 18 which carries a relay coil 25, 26 and a relay armature 23 and which is mounted on the base 11 so as to trap therebetween the terminal portions lying in contact with the base 11. The terminal 15 is connected by a conductive braid 27 to the armature 23 which is pivotally mounted on a U-shaped steel frame 18 and which carries a contact 24 movable against spring bias 20 into engagement with a fixed terminal 16 when the relay winding 26 is energized via the terminals 13, (14). The frame 18 is connected to the base 11 by a screw 22 passing through an elongated slot in the base 11 or frame 18 which permits adjustment of the frame position and hence of the contact pressure. An insulating plate 17 overlies the terminal portions lying in contact with the base 11, which is a snap fit in a casing 12. In another embodiment (Figs. 3 and 4, not shown), the relay includes a second fixed contact (31) to define a changeover relay, the contact (31) being integral with a terminal (32) having a portion clamped between the base 11 and frame 18. The free end of the frame limb 19 is engaged by a shoulder (35) on the base 11, to which the frame is secured by two screws (33, 34). As an alternative to the shoulder (35), a short tag integral with the frame 18 can be struck out in line with and in opposite direction to the frame limb 19.

Abstract: 1474745 Semiconductor memory elements TOKYO SHIBAURA ELECTRIC CO Ltd 9 Sept 1974 [21 Sept 1973] 39244/74 Heading H1K A non-volatile memory IGFET, e.g. of the MNOS type, in which information, represented by charge trapped in the gate insulation, is written in by reverse biasing the source and drain regions relative to the gate and substrate to cause surface avalanching beneath the gate insulation thereby generating charge carriers which then tunnel to the trapping sites therein, is so designed that, during writing, the region in which avalanching occurs can be completely isolated from the material of the substrate by a depletion region. In one embodiment the drain region forms part of a rectangular frame region closely surrounding the source region so that below the surface the depletion regions of source and drain overlap to provide the isolation. In the other the source and drain regions 22a, 23a, (Fig. 8) are elongated and the central gated area 43 bounded on opposite sides by the interconnected pair of gates 44 which are so biased during writing as to create depletion regions blocking any surface path to the substrate, with the source and drain depletion regions overlapping as in the first embodiment.

[Also in Divisions B2 and F2] Spray washing apparatus particularly for motor vehicles comprises a body B forming a lid of a detergent reservoir R and having a passageway P therethrough for connection with a water supply line, e.g. a garden hose H and a valve V in the passageway P having a valve member 46 movable to open or close the passageway P and a valve member D controlling orifices 60, 64 upstream and downstream, respectively, of the valve V and leading from the passageway P to the reservoir R, the member D closing at least the upstream orifice 60 when the valve member 46 is in its closed position and opening both orifices 60, 64 when the valve member 46 is in its open position. Thus, when the valve V is open, water passes via the orifice 60 into the detergent reservoir R and detergent solution is forced from the latter through the orifice 64 into the water flow through the passageway P, the resultant mixture passing through a tube T to a nozzle N (Fig. 1, not shown) to be discharged as a fan-shaped jet. The valve V may be set into a third position in which the valve member D closes the orifices 60, 64, but the valve 46 allows a flow of rinsing water through the passageway P and the discharge nozzle.
