Title: A control unit for use in laundrettes
Inventor: MAXWELL STEWART ALFRED
IPC: G07F5/18
Filed: 1963-09-25
Abstract: 1,018,579. Coin freed laundry machines. FISHER & LUDLOW Ltd. Sept. 24, 1964 [Sept. 25, 1963], No. 37681/63. Heading G4V. A plurality of laundering machines are controlled by a unit having coin operated means energizing a timer motor operating a plurality of cam switches so as to cause an electrical pulse to pass to a machine selected by a control dial, each machine having a holding relay to energize the machine and light a corresponding lamp on the control dial. In the Figure, coin switches C1, C2, C3, and C4 are closed on insertion of a sixpence, shilling, florin, and second florin respectively. One-way switches P1 and P2, and threeway switch P3, are set to determine the price to be paid, e.g. one shilling and sixpence, as shown. Insertion of a sixpence changes over switch C1, to de-energize relay B1 and close the sixpence coin slot, and to energize relay B2 and open the shilling slot. Subsequent insertion of a shilling changes over switch C2, de-energizing relay B2 to close the shilling slot, and energize a timer motor T. Switches P1, P2, P3 can be set to bypass any of switches C1 ... C4 and hold their coin slots closed. Timer motor T operates a holding cam switch CS1, and then cam switch CS2, to energize counter CT and solenoid S2 which deposits the coins into a coin box. At the same time, relay RB is energized to open contacts RB/2, RB/3, RB/4 and hold the coin slots closed, and open contact RB/1 to prevent operation of a coin return switch CR1 operating a solenoid S1 to return coins. Motor T then operates a third cam switch CS3 to supply current to whichever of washing machines W1, W2, W3 ... is selected by the control dial CD. With machine W2 selected, as shown, a relay R2 is energized, closing a holding contact R2/1 and a machine operating contact R2/2. The hold is broken by the machine timer breaking contact TC. Switch CS3, and subsequently contact R2/1, light a lamp corresponding to machine W2 at the control dial. If a machine in use is selected, its closed contact R1/1, R2/1, ... energizes a relay RA, to open contact RA/1, deenergizing relays B1, B2, B3, to close the coin slots. If the coin mechanism fails, a keyoperated switch MS and push-button P will energize the selected machine. A control unit door operated safety switch D1 is provided.

Abstract: 881,509. Valves. CLARK EQUIPMENT CO. Nov. 9, 1959 [Nov. 10, 1958], No. 37838/59. Class 135. [Also in Group XXXI] A pressure regulating valve for automatically reducing the pressure of fluid supplied to forward and reverse transmission clutches in a fork lift truck in response to application of the brakes comprises a spool 118 which is normally held by a spring 146 in the position shown in which pressure fluid can pass from an inlet 12 to an outlet 14 leading to the clutches through a selector valve by which either clutch is selected. A piston 116 attached to a rod 136 which passes freely through the spool and engages a spring abutment 144 is connected with the master cylinder of the brakes so that when the latter are applied the piston 116 is moved to the right to cause the loading of the spring 146 to be removed from the spool whereafter the pressure in the outlet is determined by balance of the spool between the outlet pressure in a chamber 154 and a spring 148 between the abutment 144 and the spool. As the braking pressure is increased the force of the spring 148 on the spool is relaxed so that the outlet pressure is reduced. The connection between the brake pedal and the rod 136 may be mechanical. Specification 799,817 is referred to.

[Also in Division H2] In a diesel-electric traction system the output torque of a constant speed diesel engine 1 is controlled by regulation of the field 3a of a generator 3 in response to the difference between the actual torque measured by a shaft deformation transducer 2 and a reference value 22, which is adjusted by an accelerator pedal 24. The regulation is effected by varying exciter fields 4b, 4c by an undisclosed device 8 in series with a battery 9. There is one traction motor 11a. . . 11d for each wheel; they each have a main series field 13 and an opposing shunt field 14 which effects field weakening at high speeds but is ineffective at low speeds when generator voltage is low and series field current high. In the event of slipping of one wheel the series field of that machine can be short circuited by a switch 16 or steps of a normally short circuited series resistor 19 can be inserted. Reversing switches 17 are provided. Normally all the shunt fields 14 are in series with each other across the generator 3, by for dynamic braking they are each in parallel with the exciter 4 which now has an auxiliary field winding 4a energized from the battery 9 through a pedal operated braking controller 25. During braking generator field 3a is energized from the battery through variable resistor 23. The machine 3 now acts as a motor in series with parallel connected groups, each comprising one of the motors 11 and one of the resistors 19. Braking is regulated by the resistors 19, and the machine continues to absorb power, by driving the diesel against its friction, when resistors 19 are shorted out.

Title: Process for reducing the length of binary signal sequences
IPC: H03M7/40
Filed: 1972-08-22
Abstract: 1409431 Digital transmission; methods of coding SZAMITASTECHNIKAI KOORDINACIOS INTEZET 22 Aug 1972 39137/72 Heading H4P In a system where binary sequences are reduced in numbers of bits by encoding before transmission, restoration is performed on reception by inverting received bits, performing an encoding function and then again inverting the resulting bits. To reduce the number of bits transmitted, a sequence is coded according to a first table  and decoded according to a second table hence decoding may be performed by inversion, coding according to the first table and re-inversion. By this means part of the decoding apparatus may be identical with that of the coder.  By applying the tables successively, long sequences may be considerably reduced in length but each successive application results in a lesser reduction hence three successive applications would normally be the maximum practicable number, e.g. a sequence of 27 bits may be reduced to 17 at the first reduction and 14 at the second.  Whilst the average operating speed of the first reducer will be higher than the second &c., as lesser numbers of bits have to be processed, the fluctuation of frequency of operation will increase in each successive stage due to differences in numbers of converted bits relative to the original sequence, i.e. half, twice, or equal. In the arrangement described each converter controls its successor.
