Title: Improvements in Cash Registers and like Calculating Machines
Inventor: GROSS HENRY
IPC: G06C11/04
Filed: 1967-06-12
Abstract: 1,179,862. Cash registers. GROSS CASH REGISTERS Ltd. 31 May, 1968 [12 June, 1967], No. 27094/67. Headings G4B and G4T. A cash register comprises amount keys, a totalizer, an indicating mechanism, a first control member, and a second control member whereby operation of (1) the amount keys followed by the first control member enters an item in the totalizer; (2) the first control member alone actuates the indicating mechanism to display a sub-total of items entered in the totalizer without zeroizing the totalizer; (3) the second control member alone actuates the indicating mechanism to display the total of items entered in the totalizer and zeroizes the totalizer and (4) the amount keys corresponding to an amount tendered followed by the second control member computes the difference between the amount tendered and the total in the totalizer (i.e. the change due) and zeroizes the totalizer. The cash register is of the type disclosed in Patent Specification 1,132,214, the TOTAL plunger of the earlier Specification corresponding to the second control member above, whereby two successive cycles are initiated automatically when the second control member is actuated following depression of the amount keys, during the first of which the amount tendered is printed on a ticket and the change calculated and during the second of which the change due is printed on the ticket. The totalizer consists of interengaging add and subtract wheels whereby the difference between the amount tendered and the total in the totalizer is calculated by complementary addition. The fugitive one is added into the righthand subtract wheel automatically when the amount keys are actuated followed by the second control member. If the amount tendered is less than the total in the add wheels, then the failure of a transfer to take place in the left-hand subtract wheel conditions the totalizer to move to the positive position and add one to the right-hand add wheels to show the amount still outstanding. The add wheels are left at 9 and the subtract wheels at 0, at the end of the second cycle, 1 being added into the right-hand add wheel at the start of the next operation.

Title: Improvements relating to automatic telephone and like selective systems
IPC: H04Q3/00
Filed: 1934-09-24
Abstract: 439,323. Automatic exchange systems. SIEMENS BROS. & CO., Ltd., Caxton House, Tothill Street, Westminster, HUMPHRIES, H. E., 61, Rochester Way, and CLARK, R. I. H., 65, Humber Road, both in Blackheath, London. Sept. 24, 1934, No. 27395. Addition to 408,439. [Class 40 (iv)] A test relay which operates over two windings in series by means of its change-over contact shunts one winding to mark the outlet busy and inserts a previously shunted auxiliary relay in the driving circuit to stop the switch. Fig. 1 shows the application to a motor-driven selector controlled by a latch magnet LM, the test relay T and auxiliary relay TA being in the common control circuit CCS. A rectifier RE, in addition to preventing operation of T by metering battery, tends to prevent operation by reduced current over the test wire of an outlet associated with a busy common control circuit CCO. The latter effect may also be obtained by a lamp in series or in parallel with T. The test wires of all the outlets are normally connected to battery over a resistance YA in the control circuit CCO, and upon operation of JB subsequent to that of the line relay, the coupling relays K are brought into circuit and that of the seized outlet energizes. Typical resistance values for T, TA, K and YA are given. In Fig. 2 the test wires include rectifiers R and are connected in multiple to YA. The coupling relays K are brought into circuit by the operation of the guard relay B (not shown), and the rectifiers R prevent earth on one test wire from being extended to the other test wires. In Fig. 3, the test wires are permanently connected through the rectifiers R to YA, while the coupling relays K are simply multipled together. The relay K of a seized outlet energizes over a circuit including all the other relays K in parallel, and its release is brought about by a break contact (not shown), in series with YA. In Fig. 4, the test circuit includes the relay K shunted by a metallic filament lamp LO which assumes a higher resistance when current passes. The resistance YA is in series with a carbon filament lamp LC which assumes a lower resistance when current passes, both being shunted by a condenser QA. This arrangement prevents two test relays holding in parallel but assists in bringing about the operation of the relay K of a seized outlet. The lamp LO may serve subsequently for supervision. Fig. 5 shows the adaptation of the circuits of Fig. 1 to a double-wiper selector, the test relays TP, TS both controlling the latch magnet LM and the auxiliary relay TA and the former having preference if both the tested outlets are idle. Switching is dependent on HC which is connected up by TA, and wiperswitching is dependent on WC which energizes in series with HC when TP is up.

Title: Improvements in the extraction of coal
IPC: C10G1/04
Filed: 1936-10-13
Abstract: In the extraction of oils from coals by treatment with organic solvents, acids are added to the coal in amount sufficient to neutralize the basic constituents of the coals and the extraction is carried out in presence of the salts thus formed.  Hydrochloric and sulphuric acids are particularly suitable and are preferably used in such dilution that the coal particles are wetted by spraying therewith.  The wetting action may be aided by the addition of wetting agents, e.g. dibutyl naphthalene sulphonic acid or agents soluble in the solvent, e.g. benzene.  100 Grms. of air-dried Mid-German bituminous coal having a water content of 12,5 per cent are sprayed with 20 ccs. dilute sulphuric acid containing 4,25 grms. H2SO4 and then extracted with benzine in a Soxhlet apparatus.  Yields of 15-19 per cent are obtained after extraction from 4-16 hours according to the amount of acid and wetting-agent added.

Abstract: 973, 207. Information storage devices; electric selective signalling. DE HAVILLAND AIRCRAFT CO. Ltd. Nov. 17,1960 [Aug. 17,1959], No. 28091/59. Headings G4A and G4H. An information storage device or counter consists of a ring of bi-stable ferromagnetic elements in which one element is in a different condition from the others and each element is so connected to its adjacent elements that the change of state may be shifted in either direction with means for selectively inhibiting shifting in one direction. The elements 10-13 are ferro-magnetic cores and each has input windings 14,15 and output windings 16, 17. According to whether there is to be shift left or shift right so line 22 or 24 is earthed by switch 23 rendering operative transistors 20 or 21 respectively. Input pulses are applied alternately to lines 18, 19. Suppose that the element 11 is in the "ON" condition and the counter is set to shift right. A pulse from lead 19 to input 14 reverses the core 11 and an output pulse on winding 17, amplified by transistor 21 is applied via input winding 15 of element 12 to an associated bi-stable circuit 27, switching both the element 12 and the circuit 27 to "ON" condition. Also the pulse is applied to the "OFF" terminals of adjacent circuits 27. The circuits 27 are so arranged that each, when in the "ON" condition, draws a current through a common resistor 28, the magnitude of which is a function of the position of the associated element in the ring. The counter may be used in a digital voltmeter as an analogue-todigital converter. Specification 973,208 is referred to.
