Title: Improvements in mechanism for actuating the indicating and printing elements of cash registers
IPC: G06C7/10
Filed: 1922-08-22
Abstract: 186,319. Krupp Akt.-Ges., F. Sept. 17, 1921, [Convention date]. Cash registers ; differential mechanism.-At each operation the type wheels are moved directly from the old setting to the new by a planet pinion mechanism the planet pinion itself however returning to its zero position during the operation and then quitting it to an extent corresponding with the new item. The differentially moved member A, provided with the trip bolt D and toothed at a<3> to actuate the totalizer through a wheel J, is driven by a plate C through a shoulder C<1> adapted to engage the notched end of the bolt. A bell-crank F pivoted at a' controls the bolt so that, when the bell-crank meets the depressed key, the bolt is pushed forward to lock with one of the notches g' and to disengage from the shoulder C'. The plate C is fast on the operating shaft 13 and has two pins C<2>, C<3>, the latter of which effects the return movement of the member A. The other pin C<2> is arranged to engage an arm E supporting a pair of pinions H, K and, during the forward movement of the shaft B, to force this arm against a stop M. The pinion H engages teeth a<3> on member A, and tne pinion K meshes with teeth l<1> on a sector L, other teeth l<2> of which engage a wheel N connected with the indicator and type wbeel. The action is as follows. The plate C, in its forward swing, draws along the bolt D and member A until the bell-crank F is tripped, whereupon the plate is disengaged from the member and continues its movement alone. The pir. c<2> now engages the arm E and forces it back to the stop M, the pinion H consequently rotating by the action of teeth a<3> and through pinion K turning the sector L and rotating the wheel N to the new setting. If the amount to be registered exceeds the previous amount, the arm E will be carried against the stop M by the forward rotation of the member A, the coi.- tinued movement of which will produce an effect through the planet pinions upon the wheel N which is consequently rotated to an extent equivalent to the difference between the two amounts. If the new amount is less, the arm E will be pushed back to the stop M after the member A has stopped and consequently the wheel N will be reversely rotated to take up the new setting. On the return stroke of the shaft B, the pin c<3> will force the member A back to normal and the arm E will move away from stop M to a distance corresponding with the new amount, the wheel N meanwhile being held by - a detent O.

Abstract: 1473831 Companders DOLBY LABORATORIES Inc 13 May 1974 [17 May 1973 5 Sept 1973] 23638/73 and 41673/73 Heading H4R A dynamic range modifying circuit comprises, in series across the input terminals, a dynamic range linear impedance Z 1  and a variable impedance Z s  including a negative resistance component R L  and being controlled 19 as a function of a signal in the circuit. As shown, an input voltage V 1  is converted to an input current i 1  by, e.g. a high impedance source, and the output V 2  is a voltage. The circuit constitutes a 10 dB compressor for frequencies above 1À5 kHz and the corresponding expander is similar except that the input is voltage V 4  and the output a current extracted at 17. For low frequency, low level input signals, the capacitive reactance is high and the - 2-16 K resistance R L  partially cancels the 3À16 K resistance Z 1  to provide a 1 K resistance resulting in an unmodified dynamic range. At high frequencies and low levels the low capacitive reactance shunts R L  and the 3À16 K resistance results in a compression factor of 3À16 : 1, i.e. 10 dB. The control circuit 19 responds to a high level signal at a particular frequency to vary the capacitance and thereby exclude that frequency from compressor action. The expander operates in a similar manner to present different impedances to the input according to signal frequency and level in order to restore the signal to its original form. The circuit constitutes a series version of Type 3 device of Specification 1,432,763. A similar circuit, employing an inductor instead of a capacitor as the variable reactance, consitutes a series version of the Type 2 device of Specification 1,253,031. Other circuits are also described in connection with Figs. 4 and 7 (not shown) in which positive resistances replace the negative resistances R L  of the above circuits in order to provide series versions of the Types 1 and 4 devices of Specifications 1,120,541 and 1,432,764 respectively, The Specification also describes circuits by which the variable impedance Z s , with positive or negative resistance components, may be realized. These circuits include a series path such as 1-2, Fig. 9, whose current i is detected and used to derive a voltage V s  which is introduced into the path 1-2 such as to simulate the characteristics of the impedance Z s  according to the Type of circuit to which this sub-circuit is applied. The circuit shown in Fig. 9 includes a fixed high pass filter C 1 R 1  and a variable high pass filter R 2 C 2 R v  and is the subject of Divisional Specification 1,473,832. Filter circuits in the loop may include limiters to prevent overshoot of the introduced voltage above one tenth of the maximum input signal level as in Divisional Specification 1,473,833, and may be arranged in parallel paths as in Divisional Specification 1,473,834.

Abstract: 1375958 FET pulse circuits INTERNATIONAL BUSINESS MACHINES CORP 18 May 1973 [29 June 1972] 23722/73 Heading H3T A circuit for selectively transmitting pulses CS to a capacitive load CL, e.g. a word or a bit line in a memory circuit through the drain to source path of an FET Q 10  comprises an arrangement Q 5  for charging the gate electrode of Q 10  prior to each CS pulse, a further arrangement Q 1 -Q 3  for discharging the gate electrode when the above transmission of CS pulses is not desired and a path Q 20  effective to discharge the load CL during each occurrence of an undesired CS pulse. In operation, initially a restore pulse R is applied to the gate of Q 5  to charge the gate of Q 10 . When it is not desired that a chip select pulse CS be applied to a particular word or bit line corresponding to CL, at least one of the SAR inputs to the gates of Q 1 , Q 2 , Q 3  forming a NOR decoder circuit is at an up level and as node C is at a low level, node B corresponding to the gate of Q 10  is discharged via an isolation transistor Q 4  before the next select pulse CS. An increase in the speed of operation is achieved by applying the CS pulse just before discharging is completed when faulty selection of a word or bit line is prevented by CL discharging via Q 20 . When a particular line is selected, all the SAR inputs are at a low level so that node C is at an up level and the gate of Q 10  is not discharged so that when the next CS pulse arrives, it is transmitted via Q 10  to the selected line, discharge path Q 20  being ineffective as node C is also at an up level. It is also stated that Q 20  can be connected between nodes A and B. Q 5  may also be connected either to node B or node C.

Abstract: 156,310. Wearham, G. A. Sept. 26, 1919. Hooks, safety.-A hook or coupling, applicable for carrying a suspended load as in a bomb-drop. ing device for aircraft or for use as a slip coupling for railway vehicles, comprises a pivoted hook member retained by a pawl so that upon release of the pawl the load is automatically released. In the construction shown in Fig. 1, the hook a, which is pivoted at b in a frame c, has a nose g adapted to be engaged by one end of a pawl j pivoted at k in the ends of links m pivoted in the frame c at n. The pawl has a hook adapted to be engaged by a pivoted trigger r coupled to a spring-controlled piston working on a pneumatic cylinder x. When the load is entered between. the frame and hook, upward movement turns the hook so as to close it against the frame and lifts the links m until the pawl engages with the nose g and the trigger r with the beak of the pawl. In this position, the line of thrust of the nose on the pawl close to the load is in the line joining the pivots k, n so that no thrust is transmitted to the trigger. Upon release of the trigger and pawl, a spring 12 moves the pawl and the hook turns on its pivot and releases the load. In place of the spring 12, the trigger r, or the pivot n may be made adjustable so that the pawl is slightly out of the dead centre position; in this case on release of the trigger, the load serves to move the pawl and affect release. In a modification the trigger is provided with a. projection 16 adapted to move the pawl on release of the trigger. Electromagnetic, mechanical or other means may be provided, in place of the pneumatic means for releasing the trigger.
