Patent GB-260610-A (GB)
Abstract: 260,610. Quijano, J. Oct. 29, 1925, [Convention date]. Multiplying-apparatus.-In a device employing the Pythagorean tables and comprising rows of numbers, each row corresponding to a single multiplicand digit and containing multiplier digits 1-9 disposed in the row at distances from one end thereof proportional to the units or tens of the product, movable or variable markers are employed to facilitate the successive multiplying processes where factors contain two or more digits. In the form shown in Fig. 1, a disc K bearing the consecutive numbers exposed at L and provided with concentric rings of holes to receive a stylus is covered by a stationary plate J having arcuate slots overlying the holes and bearing rows of figures arranged in four pairs of sectors AB, CD, &c. The various pairs of sectors are identical and the two sectors of a pair refer respectively to the units and tens values of the products. The digits in a particular row, say row 7 in sector A, are arranged in such a manner that, for example, the 4 is opposite a hole which is 8 spaces removed from the end of the slot. If, therefore, the stylus is inserted in this hole and moved to the end of the slot the disc K will show 8 at the opening L, this being the units figure in the product of 7 and 4. Similarly in sector B the figure 4 will be found 2 spaces removed in order that 2 may appear when the tens digit in the product is required. To facilitate the checking of successive multiplications markers such as T, V of different shapes or colours may be slidably mounted on radial wires S, U of frames rotatable about the centre, of the instrument. These markers are placed opposite the rows of digits in the different pairs of sectors corresponding with the figures and their denominational positions in the two factors, and the frames are relatively moved as the different partial products are determined. To sum complete rotations of the numeral disc K a. transfer pin in its passage rotates a star-wheel Q frictionally carrying a numeral wheel R. In a modification, Fig. 2, the rows of figures are rectilinearly arranged in pairs of groups AB, CD, and the markers are, carried on wire frames XY slidable over the face of the instrument. A numbered strip may be applied directly to the index-plate J in place of the sliding numeralplate used in this construction. In another arrangement, Fig. 4, the top plate J is not divided into sectors but provides for the direct determination of all products up to 81 and the rotations of the numeral disc are transferred by a cam Q and pawl-lever P to a counting-disc M. In place of markers a slate surface may be arranged in proximity to the rows of figures to enable the successive multiplications to be checked.

Title: Data reading and transmission system
IPC: G06Q40/00
Filed: 1971-04-19
Abstract: 1329482 Transmitting coded (e.g. credit) card data AMP CORP 19 April 1971 [27 April 1970] 26185/71 Heading G4T A data reading and transmission system, intended for reading coded cards such as credit cards, includes a central data storage station and a plurality of satellite reading stations each connected to the central station by a transmission line 0 and each comprising data readers 2, 6, a scanner 15, a transmitter 21 and a signal receiver 19, this latter being energized by a multiplexer (51), Fig. 2 (not shown), of the central data storage station which scans transmission lines 0 to actuate transmission of data to the central station if a "start of message" signal is being applied to line 0 by transmitter 21. In a typical operation, a card is inserted in reader 2 while scanner 15 is in its home position H. Correct insertion illuminates a lamp 4 and an inlet of AND gate 1 is energized. A second card and invoice are inserted in reader 6, which includes imprinting mechanism, to energize one inlet of AND gate 7 and a button 40 is pressed to energize the other inlet of gate 7 via gate 1. Gate 7 now activates reader 6, which also imprints the invoice if the second card is found to be in order, via a control device 8 and a non- inhibit inlet of INHIBIT gate 9 is energized. Since the other non-inhibit inlet of gate 9 is energized by the scanner in its home position H, a signal is received by scanner control device 11 from gate 9 via OR gate 10 to move the scanner to its wait position W. In this position transmitter 21 is energized to apply a "start of message" signal to line 0. When line 0 is scanned by multiplexer (51) it is momentarily shortcircuited, receiver 19 is energized, bi-stable device 20 is set to its "1" condition and a signal passes via AND gate 12 and OR gate 10 to control 11 to cause scanner 15 to scan data from readers, 2, 6 and registers 22-25, which registers include a debit or credit register 24 and an "end of message" register 25. Signals corresponding to the data pass to line 0 via a decoder 18, oscillator 17 and buffer amplifier, 16. When scanner 15 reaches its reset position R the system is recyled to its starting condition with partial ejection of the first card from reader 2 and resetting of bi-stable device 20. In alternative modes of operation, data may be set up on a switch 36 instead of using a card in reader 6 or a card may be used in reader 6, but not in reader 2. Credit may be entered directly into register 24 by depressing button 41.

Convention date, Nov. 14, 1934. [Class 38 (iv)] Temperature.-A prolonged idle period of the driving-motor b of a compression refrigerating- machine to allow the evaporator d to defrost is brought about automatically when, by reason of the accumulation of frost, the period of operation of the motor permitted by a thermostat f in the cabinet in the usual manner, is extended beyond a predetermined time. The normal control is restored after each de-frosting period. The thermostat controls the lead g to the motor and the other lead h is connected to the motor through a contact strip p on a clockdriven disc m and the coil of a magnet k adapted to withdraw a pawl l out of engagement with a notch in the disc. Normally, the thermostat opens the circuit before tho contact strip p on the disc leaves the contact arm o, and the disc is arranged to return rapidly to its original position after travelling the length of the strip. If, however, the action of the thermostat is delayed, the circuit is broken at the contacts o, p and remains open while the disc completes a revolution, during which time de-frosting occurs. Tilting mercury switches controlled by a cam may be employed. The clockwork may be wound electrically from the current supplying the refrigerating-machine.

Abstract: 1277302 Boots &c BRITISH UNITED SHOE MACHINERY CO Ltd 28 May 1969 [31 May 1968] 26838/69 Heading A3B A method of lasting includes the steps of pulling the upper over the last, moving the wipers to an intermediate position in which they just cross the edge of the insole to clamp the tensioned upper on the last, moving the pulling over mechanism away from the last, trimming the lasting margin and then completing the wiper operation. As described a machine for performing the method includes a pulling over mechanism A, a pair of lasting assemblies B 1  and B 2  and a trimming assembly T. The pulling over assembly A includes a shoe support 70 and a set of grippers 55 and is mounted on a carriage 60 which can move transversely of the machine on guide rods 58, 59 so that the assembly A can be brought into juxtaposition with either of the lasting assemblies B 1  and B 2 . Each lasting assembly B 1  and B 2  includes a toe pad 6 1  or 6 2 , a heel rest 46 1  and 46 2  and a pair of wipers 8 1 , 9 1  or 8 2 , 9 2  and can swing about a cross shaft 57 between a pulling over position (occupied by B 1  as shown) and a lasting and trimming position (occupied by B 2  as shown). The trimming assembly T includes a rotary wire brush 13 which brushes the lasting margin across the wipers in a radially outward direction. The brush 13 is mounted on a shaft 15 which can rotate in an arm 34 which is pivoted to a shaft 35. The shaft 35 is carried by an extension of a slide plate 28 which is moved lengthwise of the shoe by a piston and cylinder device 32. The brush is guided around the lasting margin by a template 16, the shaft 15 being urged into contact with the template 16 by a piston and cylinder device 36. The shaft 15 is rotated by a piston and cylinder device 41 to maintain the 'brush 13 so that it operates in a radialy outward direction. In a modification (not shown) the trimming device may take the form of a pair of trimming knives. The machine operates as follows:- a shoe assembly is placed in the machine at the pulling over station at which the pulling over assembly A and lasting assembly B 1  are in juxtaposition and is pulled over by the grippers 55. The wipers 8, 9 are then moved to an intermediate position in which they just cross the edge of the insole, thus clamping the upper, and the toe pad 6 and heel rest 46 are moved into position. The grippers 55 then release the upper and the lasting assembly B 1  is then moved to its trimming and lasting position where the lasting margin is trimmed by the brush 13 and the wipers complete their wiping operation. During this trimming and wiping operation the second lasting assembly B 2  is moved to its pulling over position and the pulling over assembly A is moved transversely of the machine to be in juxtaposition with it and a second shoe assembly is pulled over. This cycle is repeated, one shoe assembly being pulled over while another assmebly is lasted.

Abstract: 616,491. Supply systems for space discharge apparatus. PHILIPS LAMPS, Ltd. Sept. 6, 1946, No. 26868. Convention date, March 3, 1943. [Class 38 (iv)] Condenser arrangements.-In order that the voltage of a condenser supplying an X-ray tube, and being charged by rectified current, may reach a value equal to or greater than the maximum value of the alternating voltage, notwithstanding the resistance of the charging circuit, an inductance is included in the said circuit which is so rotated to the resistance and capacity thereof that its stored energy continues to raise the condenser voltage when the voltage of the charging current is less than that of the condenser. The magnetic flux in the inductance, which may be the leakage inductance of a supply transformer, is preferably so chosen that the condenser voltage is substantially constant. The load circuit may be periodically interrupted to remove its influence on the charging, as when the tube voltage is inadequate to generate rays of the desired hardness. Fig. 4 shows an X-ray tube circuit in which the condenser 1 is charged through a rectifier 5 and resistance 2 from a transformer 4, the inductance of which, if not sufficient, is supplemented by an inductance 6. In order to cut off the tube 3 when the voltage is insufficient, a grid 7 is biassed to a voltage dependent on the charging current by a connection to a tapping on the resistance including a voltage 9 so that the tube may conduct only when the charging current is substantially zero. Alternatively, a polarized relay may control the load circuit.
