Abstract: 618,892. Statistical-apparatus. COMPAGNIE INDUSTRIELLE DE MACHINES AUTOMATIQUES DE COMPTABILITE. Aug. 1, 1946, No. 23009. Convention date, Feb. 22, 1943. [Class 106 (i)] In a record-card controlled machine having a comparing device comprising two registers for primary and secondary numbers respectively, each register including a set of relays 1 to 5 and S1 to S5 for each denomination. The relays of corresponding denominations control contacts in a comparing circuit whereby, according to the setting of the contacts, a testing impulse (entering at 19) is passed to one of three output wires indicating (a) primary number lower (wire 22) ; (b) primary number higher (wire 21 ; or (c) equality, in which case the impulse passes (by wire 20) to the comparing circuit of the next lower denomination, and so on. In the embodiment, the relays are arranged according to a code in which relays 1, 2, 3, 4 and 5 represent the odd numbers 1, 3, 5, 7 and 9, when energized alone, but when relay 5 is energized together with one of the relays 1 . . . 4, these latter represent the numbers 2, 4, 6 and 8. A relay 13 of the primary register controls the circuit by which the relays S1 to S4 of the other register, control the comparing circuit, unless its opposite number S13 is energized also, and vice versa.

Abstract: 1,022,323. Light modulation. STANDARD TELEPHONES & CABLES Ltd. June 14, 1963 [June 15, 1962], No. 23126/62. Heading H4F. Light-modulating apparatus comprises a microwave resonator 6, an optical resonator in the form of an interferometer made up of a pair of partial optical reflectors 1, 2 and an electro-optical element 4 within the microwave resonator and in the path of the optical wave within the optical resonator. The optical resonator is " tuned " so that it passes approximately 50% of the incident monochromatic light 3. The electro-optical element responds to the electric field in the microwave resonator to produce a variation in its refractive index with a consequent change in the tuning of the optical resonator and the transmitted light. The electro-optical element comprises a crystal of potassium dihydrogen phosphate in the form of a right circular cylinder with the physical axis coinciding with the Z-axis of the crystal. A polarizing filter 10 in the incident light beam is rotated so that the light is polarized to match one of the principal refractive indices of the element. The end faces of the element are bloomed to reduce optical reflection. Cooling of the optical element may be effected by thermal contact with the end faces of the resonator and/or by blowing air through the resonator. Light source 9 may be an optical Maser. A multi-channel modulating system is described with reference to Fig. 6 (not shown), where a beam of monochromatic light is split by a cylindrical lens structure into a plurality of partial beams which pass through separate modulators operating at different microwave different optical frequencies and are then recombined to form a single beam.

Abstract: 1,057,151. Road traffic measurements. DECCA Ltd. Aug. 27, 1965 [June 8, 1964], No. 23693/64. Heading G4Q. The output of an inductive loop vehicle detector (13), Fig. 1 (not shown), passes in parallel to an integrating circuit (resistance 31 and capacitor 32) and to a pulse-shaping circuit which produces a standard output pulse for each rise in detector output. The pulseshaping circuit may comprise a capacitor (33) feeding a relay (34) in parallel with a rectifier (35) arranged so that only increases in detector output operate the relay. The relay contacts (36) control a normalizing circuit (37) producing a standard output pulse for each vehicle detected, and these pulses feed an indicator (38) which may be a counter or leaky integrator giving a measure of traffic flow. The output of the first integrating circuit (31, 32) is indicative of the number of vehicles within the detector loop (10) and will rise if the vehicles are stationary; this output may be used to operate an alarm (40) or a warning light on a display map when it exceeds a predetermined level, e.g. indicating three stationary vehicles in a loop adapted to accommodate four vehicles. Provision may be made for re-setting the alarm as soon as a flow pulse is produced by the normalizing circuit (37), or after two or more flow pulses are produced. The computer unit (30) may be located at a central control point remote from the detector (13).

Abstract: 480,761. Master control of D.C. motors; actuating controllers; automatic control systems. WESTINGHOUSE ELECTRIC & MANUFACTURING CO. Aug. 31, 1936, No. 23765. Convention date, Aug. 31, 1935. [Class 38 (iii)] [Also in Group XXXV] Varying E.M.F.-In a Ward - Leonard motor control system the generator field is included in a balanced impedance bridge having control elements connected across the two diagonals. The invention is described as applied to an elevator system. The generator field Gf is connected in one arm of a Wheatstone Bridge circuit, the other arm being constituted by resistances r1, r2, r4, and one diagonal of the bridge contains the armature of a regulating generator Ra, the other diagonal being connected to a variable potentiometer resistance P1. The regulating generator has three fields, one Rs connected in series with the armature of the driving motor M opposed by a second Rf connected across the motor armature and assisted by a third Rd connected in series with the generator field. The Specification explains mathematically that the generator Ra operates to maintain the speed of the motor M, as represented by its back electromotive-force, directly proportional to the control voltage applied from the potentiometer P1. in spite of variable characteristics of the system such as load changes, temperature changes, &c. The field Rd of the generator Ra operates to prevent hunting of the system. The control is effected by a car switch MS which controls forward and reverse contactors U, D, and a relay X which energizes indicator relays E, F, operated on by plates in the lift shaft, to slow down and stop the driving motor. The forward and reverse contactors control a speed relay V which puts into operation a pilot motor CMa operating a cam-shaft controller actuating contacts C1- C8, to vary the potentiometer resistance. P1. The pilot motor is under the control of limit switches C9, C10. In a modification the pilot motor and cam-shaft controller is not employed, the relay V in this arrangement operating on a single step of resistance in the supply to one diagonal of the Wheatstone Bridge circuit.
