Patent GB-2475895-A (GB)
Title: Combination lock
Inventor: LINDEN PAUL VAN DER
IPC: E05B37/02
Filed: 2009-12-04
Abstract: A combination lock with a series of rotating disks, and each disk comprises an inner 4 and outer 1 concentric rotating ring and a sleeve 11 which displays the sequence information. The inner disk 4 contains a gate 3 and a dog 5. The outer disk also has a gate 3 and a spring loaded pawl 7. To open the lock both gates have to be aligned with the slot 13 and tooth 19. The sleeve is rotated which, via contact between the dog 5 and pawl 7, rotates both the inner and outer disks in a first direction until gate 3 is aligned. The sleeve is then rotated in the opposite direction and only the outer disk 1 rotates until gate 2 is also aligned. The lock can then be released. The concentric rotating rings also feature false gates 6, 10 which prevent opening by manipulation.

Title: Transmitter potentiometer

Filed: 1957-03-27
Abstract: 865,142. Measuring temperature and strain. ROBERTSHAW - FULTON CONTROLS CO. March 27, 1957 [April 19, 1956], No. 10042/57. Class 40 (1). [Also in Groups XXXV and XXXVI] A direct current signal from a transducer is amplified by a force balance arrangement (see Group XXXVI) in which the signal is applied to the deflecting coil 63 of the balance in series with an adjustable stabilized voltage from wires 16, 17 developed across resistors 58, 59 and with a resistor 68 which is also in the output circuit of the force balance. The resistors shown within the dotted rectangle are mounted on a card which can be replaced for measurements of different ranges and different kinds. Temperature measurement, Figs. 1, 3.-The voltage developed by the thermocouple 55, Fig. 1, is opposed by a stabilized voltage at 58, 59, which is adjustable for zero setting and is temperature-dependent to compensate for variations of cold-junction temperature, and by the voltage developed by the output current of the balance across resistor 68, the value of which determines the range of measurement. In an arrangement for measuring the difference in temperature between resistance bulbs 120, 121, Fig. 3, the resistors shown in the dotted rectangle are substituted for those in Fig. 1. When this has been done, a bridge circuit is formed which is energized from the stabilized source 16, 17 and has its output diagonal connected to the input coil of the force balance, the output current from the force balance flowing in a part of one bridge arm in a direction to balance the bridge. The arrangement shown may be modified by substituting a fixed resistor for one of the temperature-sensitive bulbs. Measuring strain.-A bridge of wire strain gauges is supplied from the stabilized source and its output is applied with an additional zero setting voltage, via a set of resistors substituted for those shown in Fig. 1 within the dotted rectangle, to the input of the force balance, resistor 124 playing the part in this case of resistor 68.

Abstract: 610,374. Cash registers. NATIONAL CASH REGISTER CO. April 3, 1946, No. 10270. Convention date, Dec. 9, 1941. Addition to 610,400. [Class 106 (i)] [Also in Group XV] A record material sorting device has a series of compartments, each with a shutter which is moved to a vertical position through electromagnetic means at the manual operation of a related device in an associated accounting machine. The invention is described as applied to a central control accounting machine commonly used in bank clearing houses. The machine has several compartments, corresponding to the several banks, normally closed by spring-pressed flaps 90. When a cheque is dealt with, the key corresponding to the bank is depressed to energize a,'magnet and lift the corresponding flap 90, the underside of which is contrastingly coloured to attract the attention of the operator, who places the cheque manually in the uncoverod compartment. A rubber buffer 95 eliminates noise when the flap is lifted.

Abstract: 527,187. Electric locomotives. GENERAL ELECTRIC CO., Ltd., CROFT, E. H., and ROBSON, N. W. April 3, 1939, No. 10354. [Class 104 (iii)] An electric locomotive comprises two parts 1, 2 normally coupled and each provided with one or more driving motors and a pantograph collector 3 or 4 operated by pneumatic devices 5 or 6 supplied with compressed air from the other part through a valve 16 or 17, three way cock 18 or 19, safety release cocks 20 and 21 or 22 and 23, and a coupling hose 14 or 15. The cocks 20 and 23 or 21 and 22 are coupled together and interlocked with a door giving access to high tension equipment, so that the opening of the door releases the collectors. The collectors are normally connected by a power jumper 11, which, when the parts 1 and 2 are coupled, masks emergency air supply points 28, 29, so that it is impossible to couple the collectors while an emergency supply connection between 26 and 28 or 25 and 29 is in place owing to 1 and 2 being uncoupled.

Title: Improvements to switching units in telecommunications
Inventor: METIVIER MAURICE
IPC: H04N5/268
Filed: 1955-04-12
Abstract: 806,636. Television. SOC. NOUVELLE DE L'OUTILLAGE R. B.V. ET DE LA RADIOINDUSTRIE. April 12, 1955, No. 10522/55. Class 40 (3). A switching unit to connect a single output channel to any one of a plurality of input channels is arranged so that switching takes place only during a blank interval, i.e. period of no information, in the channels and the switching operation is so short that it is completed well within the blank interval so that no spurious signal is introduced. The invention is stated to be applicable to any communication system where there are blank intervals in the signals, television, multiplexing and audio systems being referred to, but is described in detail only as applied to television. In Fig. 3 a positive switching pulse is caused to appear on one of leads A-F and actuate an associated gate stage 1-6 (shown in detail in Fig. 2, not shown) so as to connect to a common output one of six video channels. The solution is effected by the change-over of a key on control desk 11 and the operation takes place during the frame blanking interval under the control of line synchronizing pulses from source 21 which are gated to the unit via a switch 22 operated by the frame blanking generator 20. At the onset of the frame pulse, a binary counter 33 is reset to an initial position through stages 56-58. Shortly thereafter, due to delay 23, switch 22 is opened and line synchronizing pulses are passed to step the counter. By means of a diode matrix 32 the counter operation causes positive pulses to appear in turn on conductors 50-55. The conductors are connected to the switching leads A-F, but the pulses are normally rendered ineffective by diodes D1-D6. The changeover of a key on desk 11 renders the associated diode inoperative and allows a pulse to pass to the switching lead and operate the gate stage for the selected channel. The pulse on the switching lead is also applied to switch 22, is effective to close it and thereby stop further operation of the counter. The unit then rests with the selected channel connected until the onset of the next frame pulse when the counter is reset to its initial position and restepped until the selected channel is again switched. Lowpass filters 43, 48 are connected between conductors 50-55 and leads A-F to prevent transients due to the counter operation appearing in the video channels. A D.C. motoring circuit is also preferably provided in the common channel to eliminate transients. The restorer is switched, is operated during the latter part of the frame operation. A fade-over or mixing system may be provided by using two units according to the invention which are arranged to apply their outputs through separate controllable amplifiers to a common channel. Specifications 615,638 and 787,425 are referred to.
