Title: A voltage comparison circuit
Inventor: RATAJ MIROSLAV
IPC: G01S7/22
Filed: 1959-03-05
Abstract: 873,808. Pulse generator circuits. TESLA, NARODNI PODNIK. March 5, 1959, No. 7680/59. Class 40(6) [Also in Group XXXVI] A circuit for comparing a voltage waveform B (Fig. 1) with a multi-level reference voltage comprises an input applied over resistor 1, (Fig. 2) to a comparator circuit 2 and to a trigger circuit 3. At a predetermined level the comparator produces a negative going pulse, and recloses on further increase of the input, while the trigger circuit produces a rectangular pulse which is coupled to an integrating pentode memory circuit 4 (opened at the commencement of the measurement) where it charges a capacitance to a steady voltage which is superimposed substractively on the input waveform over resistance 5. The comparator responds again to the net voltage to produce a further output pulse and again charges the memory circuit capacitance, after which the process is repeated until the entire amplitude of the waveform has been compared at successive points with the arithmetically incremental voltage on the memory circuit capacitance, which increases one step per measurement cycle. The resultant output is a train of pulses A (Fig. 1) of equal amplitude each representing the passage of the input waveform through one of a successive series of incremental reference voltage levels equally spaced. In Fig. 3 the input waveform is applied to a pentode E 1  which conducts to produce a negative going anode pulse and cuts off on increased input by suppressor bias from its cathode resistor. The trigger circuit comprises retroactive cathode coupled triodes E 2 , E 3  operative to produce a positive anode pulse which is diode-capacitance coupled to charge stepwise the memory capacitance C 2  of Miller integrating pentode E 1  (which is opened at the beginning of each waveform measurement and closed and discharged at the end thereof by a suppressor grid control pulse) to whose anode and capacitance C 2  the input waveform is applied. The value of each incremental voltage step is variable in response to the ratio of coupling capacitance C 1  to memory capacitance C 2 .

IPC: A47C9/06
Filed: 1948-03-16
Abstract: 656,572. Tip-up seats. HALLAM SLEIGH & CHESTON, Ltd. March 16, 1948, No. 7823. [Class 52 (v)] A tip-up seat comprises a torsion bar which causes the seat to tip up when released from a horizontal position. The seat bottom 1 has an underframe to which are attached side flanges 8, 9. A fixed rear attachment member 10 has brackets 11, 12 between which the seat bottom is pivotally attached. These side brackets receive flanged caps 13, 14 which have square-sectional recesses to receive trunnion members 15, 16. The trunnion members have square holes to receive the ends 2a, 2b of a laminated torsion bar. The circular aperture of a square bush 22 forms a bearing for the circular shaft of the trunnion 15 so the trunnion 15 is rotatable within the cup 13. The square head 19 of the trunnion is closely engaged by the cap 14 thus holding it against rotation. A bush 24 similar to bush 22 can turn around the circular part 20 of the trunnion 16. A square tube 25 rigidly secured to the seat bottom has one end connected to the trunnion 15 and the other connected to the square bush 24. As the seat is moved to the horizontal position the tube 25 turns with the seat bottom and rotates the trunnion member 15 the other end tube turning freely on the fixed trunnion 16. The bar 2 is thus twisted about its axis and on release of the seat causes it to tip up to its out of use position. Stops are provided to limit the upward and downward movements.
