IPC: G11C11/416
Filed: 1968-05-27
Abstract: 1,217,017. Read-write arrangements for storage cells. MOTOROLA Inc. 27 May, 1968 [10 July, 1967], No. 25180/68. Heading H3T. A read-write circuit for a transistor memory cell comprises a pair of read-write points connected to the cell, each point being connected to a constant current switching circuit controlled by a write transistor and to an output transistor indicating the state of the cell. Considering the left-hand half of the Fig. 1 arrangement, the constant current from resistor 18a flows through transistor 16a to input-output point 5a and from there either to the storage cell 9 or to transistor 10a depending upon the state of the cell. Accordingly the output from transistor 10a and thus from the current switching output stage. 7 also depends on the state of the cell. A write 1" signal increases the conductivity of transistor 12a. Emitter 40a raises the potential of the read-write point 5a while emitter 42a directs the current from resistor 18a via 14a to the base of transistor 10b so that the potential at the base of 10b and thus at the read-write point 5b is lowered. The complementary changes in potential at the read-write points 5a, 5b sets a "1" into the cell. The diodes in the circuit provide temperature stabilization. The storage cell may be as shown in Fig. 2, in which case setting is effected by controlling in a complementary manner the potential of emitters 251 and 271 with respect to the other emitters.

Abstract: 775,956. Gramophones. KNECHT, E. Sept. 2, 1955, No. 25326/55. Class 40 (2). A device for automatically placing the stylus down in the entry track of a gramophone record, comprises a guide member which holds the stylus away from the record during an outward sweep of the tone arm across the record until the edge of the record is reached, a locking member which holds said guide member in its operative position, a trailing member which releases the guide member to an inoperative position when the record edge is reached to thereby lower the stylus to the record, and a member for subsequently resetting the guide member to the operative position. In the first embodiment, Figs. 1 and 2, the guide member comprises an arm 3 which is locked in its operative and inoperative positions by a spring 5 which presses on a squared boss 4. The arm 3 is provided with a slipper foot 2, which with advantage could be a wheel, and which serves to hold the stylus away from the record 6 while the tonearm is caused to slide outwardly across the record. When the foot 2 slips down over the edge of the record, a friction member 7 on the arm 3 comes into contact with the record edge and causes the arm 3 to be flung up into the inoperative position, shown dotted in Fig. 1, whereby the stylus is lowered on to the record. An arm 10 is provided on the arm 3 to cooperate with the turntable spindle on the tonearm rest for the purpose of restoring the arm 3 to the operative position. In the second embodiment, Figs. 4 and 5, the guide member comprises a wheel-carrying lever 13 pivoted at 14 and held in the operative position against the action of a spring 15 by the slot 21 in an arm 20 pivoted at 18 and engaging a pin 22 on the lever 13. As the wheel 12 slips over the edge of the record, a projection 23 on the arm 20 comes into contact with the edge of the record and lifts the slot 21 clear of pin 22 so that the lever 13 is retracted by spring 15. The lever 13 is restored to the operative position by a right-handed movement, as viewed in Fig. 5, to the end of a resetting member 16.
