A direct-current machine 1 having a commutator is protected against short circuits by an arrangement comprising a detector 5, a highpass filter 9 for separating the higher frequency components which usually precede a short circuit, a level detector 15 responsive to those components to produce a signal to effect interruption of the supply to the machine. The detector 5 may be a transformer connected to the machine by capacitors (Fig. 2, not shown). The output from the filter 9 may be amplified by a transistor amplifier 10 and rectified by a circuit 12 which has a full-wave rectifier and a resistance capacity circuit having a charging time constant one third of the discharging time. The signal from the detector 15 is applied to a memory circuit 17 which may include a thyristor having a delayed cut-off. A relay 18 connected to the circuit 17 may interrupt the supply to the machine 1. Fig. 6 (not shown) illustrates a plurality of such arrangements which share a common circuit 17 and relay 18.

Patent GB-648785-A (GB)
Abstract: 648,785. Totalizators. UNION TOTALISATOR CO., Ltd., and HANDLEY, J. Jan. 16, 1948, No. 1485. [Class 106 (i)] The total number of each denomination of tickets issued on all competitors and the total number of each denomination of tickets issued on each competitor is shown on separate counters. A ticket-issuing machine TIM has keys CK1 ... CK4 corresponding to the competitors and keys SKA ... SKD corresponding to the value of the bet. If, e.g., keys CK2 and SKC are closed, in due course the assignor actuates relay S3 to close contacts s1, s2, so that relays C2 and SC are actuated, thus closing contacts C2/1 and Sc1 to selectively energize relay 2C in the co-ordinate bank 1A ... 1D, 2A ... 2C, 3A ... 3C, 4A ... 4C. Relay 2C actuates an individual counter to record the total number of bets of value C on competitor 2. The other relays in the co-ordinate bank similarly actuate counters to record the total of bets of the appropriate denomination on the appropriate competitor. Relays C1... C4, SA ... SB also actuate the normal totalling apparatus to evaluate the value of all bets and the sums wagered on each competitor. Relay SC also closes contact SC2 to energize relay TC which actuates a counter to record the total number of bets of denomination C on all competitors. Relays TA, TB, TD make similar records for other denominations of bets. The co-ordinated relays 1A ... 4D close contacts, e.g. 2c1, while relays TA ... TD close contacts, e.g. te1, to actuate release relay R1; the coordinated relays 1A ... 4D also close further contacts, e.g. 2c2, in the circuit of relay GD, which energizes if two or more of the further contacts, e.g. 2c2, are closed simultaneously, thus signalling a fault.
Patent GB-710318-A (GB)
IPC: G06C23/02
Abstract: 710,318. Calculating-apparatus. NATIONAL CASH REGISTER CO. June 18, 1952 [July 20, 1951], No. 15388/52. Class 106 (1). [Also in Group XXXVII] In a calculating machine having a number of denominational banks of keys, an amount is set up by partial depression of the appropriate keys, a detent for each bank latching the partially depressed key, and the machine cycle is initiated by full depression of any one of the amount keys which moves a corresponding one of a number of members, one of which is associated with each bank, the members co-operating with a bail which operates a switch to initiate a cycle of operation. The amount keys 1, Fig. 10, are latched in their normal operative positions by detent bars 51 associated with the banks of keys. If a key is further depressed, its stem co-operates with a corresponding cam notch 41 in a slide 40 passing through slots in all the key stems of the bank. The slide 40 is thus moved forwardly and a depending finger thereof rocks a bail extending across the machine and having a tail 55, Fig. 4, which is thus moved to allow a switch 60 (see Group XXXVII) to close. A solenoid 22 is thus energized to rock an arm 19 which rocks a latch 16, Fig. 5, to allow levers 8, 10 fast on a shaft 9 to be rocked by a spring 11. A stud 7 in the lever 8 rocks a lever 6 to close the motor switch 4, the lever 6 being held by a latch 14 until the end of the cycle when the latch is rocked by a cam 15. When the arm 19 is rocked, a link 62 rocks a lever 63 which holds the switch 60 in its unoperated condition for the remainder of the cycle. The bail which operates the switch is loaded by a spring one end of which is adjustably secured in the keyboard frame so that the extra pressure on the key required to start the machine may be adjusted. A cut-out switch in the solenoid circuit enables the amount-key controlled initiating mechanism to be rendered ineffective. If desired, the subtraction bar may be arranged not to initiate a cycle of operation, the cycle being started by full depression of an amount key. Specification 693,659 is referred to.

Patent GB-789385-A (GB)
Abstract: 789,385. Recording-apparatus. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Feb. 27, 1956 [March 10, 1955], No. 7126/55. Class 106 (4). A potentiometric recorder with a. linearly movable shaft 14 comprises y pens spaced apart along the direction of movement of the chart and capable of moving together in the direction transverse to the movement of the chart, means for moving the pens to x transverse stations with zero signal input so that xy areas are available on the chart to record quantities measured at xy points by selection of the appropriate pen and the appropriate station. Apparatus for recording the voltage across each of 48 pairs of terminals 155, Fig. 8, successively in repeated cycles over 24 hours comprises a three-bank uniselector switch whose wiper arms 138, 139, 140 are stepped on from contact to contact at 30 sec. intervals, successively sampling each voltage by connecting one terminal 156 of each pair to a bridge circuit through the wiper 140, while the wiper 139 selects each pen P1 to P8 in turn for six successive samplings and the wiper 138 adds in resistances 142 one by one in cycles of six to shift along the potentiometer wire 51 the zero position of the wiper 52 with which moves a sliding bridge structure 15, Fig. 7, carrying an arm 16 holding eight spaced electrode " pens." During the last second of each 30 sec. interval an electromagnet 108 causes all the pens to rock into contact with the chart 14, followed by the operation of a change-over switch 145 to discharge a condenser 146 through the selected pen to record the value of the voltage indicated .by the position to which the wiper 52 has been - moved by servomotor mechanism 159 to achieve balance of the bridge circuit. Chart driving mechanism. The chart 14 is driven from an upper drum frictionally held on a shaft 65, Fig. 3, driven at constant speed against the torque introduced by a band brake 69, which torque is greater than that given by the friction between the drum and shaft, so that the chart can be advanced by hand about 14 inches at the end of every 24 hours in preparation for the next 24-hour cycle, without introducing slack into the drive to the shaft 65. The chart is held in tension by a spring 81, Fig. 3a, interconnecting a shaft 78 and a knob 80 which is turned to tension the spring and advance the chart. The tension is prevented from escaping by a pawl 149 acting on gearing secured to the knob 80 and, while taking up the slack in the chart 14 as rotation of the drive shaft 65 releases it from the upper drum, the spring 81 causes the strip to be taken up by a drum 82 secured to the shaft 78. Electrode " pen " holder arm. Two blocks 89, 90, Fig. 5, fixed to a channel section member 91 house a push rod 92 operated by a lever, pivoted in the lower, forked end 106, to rock eight bellcrank levers 94 to bring tungsten wire tips of electrodes 96 into contact with the chart. Electrical connection is made from the electrodes 96 through wires 99, connectors 98, cable 20, wipers and bus-bars to the contacts of bank 152 of the uniselector switch.

Patent GB-2020514-A (GB)
Title: Data Receiving Apparatus
IPC: H04L1/08
Filed: 1979-03-30
Abstract: Data receiving apparatus for receiving repetitively transmitted blocks of data, stores a block of data (register 10), and compares (comparator 12) each received byte in incoming data DI with the corresponding stored byte in D(n). If the bytes match (M) a data selector 15 selects either byte for storage and sets a flag bit for that byte in a register 14 to 1. If the bytes do not match, the data selector selects the new byte when the existing flag bit is 0 and selects the old, stored byte when the existing flag bit is 1, in either event setting the flat bit to 0. In this way the probability is that each stored byte is an error free byte. A status circuit 16 signals when all flag bits are not 1 to indicate that suspicion nevertheless attaches to the block as stored. <IMAGE>
