Abstract: 793,653. Seats. LORENZ, A. Nov. 17, 1955 [Nov. 26, 1954], No. 32905/55. Class 52(2) In a reclining chair having a rigid back and seat unit pivoted to a support and a leg rest which can be projected by a linkage when the unit is tilted back on its pivot, a bell-crank is pivoted to the support and has its long arm connected to the leg rest linkage through motion-multiplying means and the unit has an actuator to the rear of its pivot and having driving engagement with the short arm of the bell crank. As shown in Fig. 1, the back and seat unit 18 is pivoted at 24 to the support 10 and, when rocked rearwards, bears on a bell-crank 30 which actuates a second bell-crank 38 which, through a controlling link 44, extends the leg-rest 26. The leg-rest is swing- ably suspended by two front links 46, 54 respectively pivoted to the support at 48 and to the front of the seat, but in modifications both the front links can be pivoted to the support or to the seat. Rearward rocking is limited by bell-crank 30 abutting a fixed stop 62 and forward rocking, by the seat abutting a fixed stop 60. The bellcranks 30, 38 are connected together with lost-motion at 42. The arrangement is such that the leg-rest can be manually extended without rocking unit 18 and is held in adjusted position by friction means at its pivots. In a modified form, Fig. 2 (not shown), a fixed stop is abutted by the seat in the forward limit position and by the front link 46 in the rear limit position. One of the bell-cranks can be omitted. The end of the first bell-crank can be pivoted to the unit 18 instead of sliding thereon but in this case, the leg-rest cannot be extended independently of rocking the unit 18.

Abstract: 1432406 Transistor pulse circuits HITACHI Ltd 12 July 1973 [12 July 1972] 33378/73 Heading H3T A buffer circuit incorporating a booster circuit and employing IGFETs comprises a booster portion including a transistor T 6 , impedances T 7 , T 5  and a capacitor C, a buffer circuit portion T 1 -T 4  including an inverter T 3 , T 4  connectable to a supply source V DD  different from the source V GG  to which the booster is to be connected whereby, in operation with clock pulses applied to the gate of T 6  and with input pulses applied to the gates of T 1 , T 4 , an output signal is obtainable at the junction of the conduction paths of T 3 , T 4 . The impedances T 7 , T 5  may be constituted by a resistor, a diode, a series combination of a resistor and a diode or by an FET as shown. In operation, clock pulses # 1  turn on T 5 , T 6  to charge the capacitor C to the supply potential. Subsequently clock pulses # 2  turn on T 7  to add a further V GG  voltage to that already stored in C so that when T 1  is held non-conductive by the input voltage V in , the source potential of T 2  is that of V GG . Hence the final output at the source of T 2  is boosted to a high value approximating the supply potential. The # 2  clock pulses in addition periodically replenish the charge lost by capacitor C. In the alternative embodiment of Fig. 5 (not shown), a further capacitor is charged periodically during the # 2  pulses for boosting the output voltage still further.

Filed: 1957-10-25
Abstract: 848,578. Pulse amplifying circuits. CHIRANA PRAHA NARODNI PODNIK, and OBRAZ, J. Oct. 25, 1957 [Oct. 26, 1956], No. 33380/57. Class 40(6). In a pulse amplifier comprising a number of stages each followed by a resistance capacity coupling, a diode is connected to the input of the coupling of one of the stages so as to suppress overswing generated in the coupling of an earlier stage, the coupling following the diode having a time constant which is smaller than that of the earlier coupling by at least one order of magnitude. By this means secondary overswing, that is overswing of reverse polarity from the original, may be avoided. Thus, in Fig. 3, overswing generated by the coupling network C o R o  is removed by a diode D and the following coupling C 1 R 1  and has a time constant at least an order of magnitude less than C o R o . A further diode D 1  suppresses overswing generated by the coupling C 1 R 1  and this diode may be shunted by a resistor. In an alternative embodiment the capacitor C 2 . is omitted and the diode is biased by connecting it to a potentiometer.
