Title: A dc motor control apparatus
IPC: H02P7/295
Filed: 1969-10-14
Abstract: 1292964 Photo-electric projector focus control CANON K K 14 Oct 1969 [16 Oct 1968(2) 6 June 1969 20 Aug 1969] 50419/69 Heading G1A [Also in Divisions G2 and H2] A D.C. motor 32 is supplied from an A.C. source 30 through the secondary winding 31A of a transformer 31 in series with bridge rectifier 33. A silicon controlled rectifier 34 is connected across the rectifier 33 and its gate is connected to a resistance bridge 35 which is supplied from transformer winding 31B. As shown, when the resistance bridge is balanced, the rectifier 34 is not fired so that the motor is de-energized. Displacement of arm 36<SP>1</SP> from a neutral position unbalances the bridge 35 whereby the rectifier 34 becomes conductive to supply the motor with half-wave current, the firing-angle of the rectifier being dependent upon the amount of displacement of the arm, and the motor being reversed in accordance with the sense of the displacement. In another arrangement, the output of the resistance bridge is connected across the emitter and base of a transistor which is in parallel with the silicon controlled rectifier across the D.C. terminals of the bridge rectifier, Fig. 5 (not shown). When the resistance bridge is balanced, the transistor and silicon controlled rectifier are conductive, and the motor is energized with A.C. so that it remains at standstill. Unbalancing of the resistance bridge causes the motor to be fed with half-wave current, the arm of the bridge being coupled to the motor for automatic re-balancing.  In a further embodiment, the resistance bridge comprises a photo-conductive element which receives reflected light from a slide forming part of an automatic focusing device for a projector. When the slide deviates from a normal position, the bridge is unbalanced and the motor is energized to restore the slide or the projector lens to the correct position, Fig. 10. In a portable arrangement, a battery is connected to an inverter which feeds the motor through rectifiers in anti-parallel, Fig. 11 (not shown). The control device may be applied to a device for automatically controlling the exposure value of a camera. The motor circuit may include P-gate and N-gate SCRs in anti-parallel, the gates being connected to a photo-metric bridge. Aperture diaphragms for controlling the light incident upon the photoconductive element are interlocked with the motor, Fig. 12 (not shown). The motor may be associated with a centre-tapped transformer and SCRs of the same type, Fig. 13 (not shown). The SCRs in the motor circuit may be shunted by diodes, the control bridge being supplied from a third transformer winding, Fig. 14 (not shown).

Abstract: 1,211,358. Nitrogen-doped Group III-V semiconductor. WESTERN ELECTRIC CO. Inc. 7 Nov., 1967 [21 Noy., 1966], No. 50585/67. Heading C1A. [Also in Division H1] Nitrogen-doped Group III-V semi-conductor compounds are produced by preparing Group III-V material under nitrogen-free conditions, preparing a melt of the Group III constituent under nitrogen-free conditions and maintaining it at a constant temperature for 1-2 hours, thereafter adding to the Group III element without the admission of air a minor proportion of the Group III-V material and a required quantity of a nitrogen compound of the Group III constituent, plus any required impurity, sealing the mixture into a container, heating the mixture to its melting point and cooling slowly to effect crystallization. Gallium phosphide is made by passing phosphine over gallium at 850-1100‹ C. and crystallizing the gallium phosphide, maintaining a body of gallium at 1100‹ C. for 1-2 hours, adding the gallium phosphide crystals in a proportion of 1 to 10 by weight and gallium nitride in a required amount plus any required impurity, sealing the mixture into a container, heating to 1200‹ C. and slowly cooling to 850‹ C. to produce nitrogen-doped gallium phosphide. The cooling may take place over 10 hours. The gallium for the initial step may be contained in an alumina boat heated in an alumina-lined furnace. A relationship between the mole per cent of GaN added to Ga and the concentration of N atoms per c.c. of material is shown graphically (Fig. 2, not shown).

Abstract: 507,361. Naphthenate driers. MINICH, A. March 29, 1938, No. 9552. [Classes 1 (iii) and 95] Basic salts of naphthenic acid with drying metals are prepared by reacting a solution of an alkali metal naphthenate containing free alkali with a water-soluble salt of the metal containing sufficient metal to combine with the naphthenic acid and react with the free alkali present. After washing and drying, the precipitated basic salt is obtained as a powder which is insoluble in oil or water, and by reason of its high metal content forms an efficacious drier, particularly for printing inks. Examples relate to the production of basic naphthenates of cobalt, manganese, and lead containing respectively 18, 24, and 64 per cent of metal, and the production of basic naphthenates of iron, cerium, thorium, vanadium and nickel is also referred to.

Abstract: 1,090,460. Programmed control of position. LONDEX Ltd. Dec.14, 1965 [Dec. 18, .1964], No. 51684/64. Heading G3N. An arrangement for moving a member to one or other of a number of preselected positions within a total range of movement comprises a plurality of uniquely positioned preset servotransmitters which are selectively connected to a servo receiver positioning the member to the unique position. As shown, the light intensity in film printing machine is controlled by a binary-coded programme tape 2, which is prepared by observation of a negative 12. During printing the tape is synchronized with the movement of the negative by stepping the tape in reader 1 by a switch 10 actuated by notches 11 in the negative. The signals from the tape reader 1 are decoded by a unit 3 which energizes the appropriate relay 1-22 connecting a servo-transmitter 5/1 - 5/22 to a servo receiver 6. The receiver 6 through a servo system, comprising an amplifier 7 and a servomotor generator 8 positions a shaft 9 connected to a shutter, not shown, varying the intensity of the printing light. The servo-transmitters 5/1 - 5/22 are setup manually using a binary-coded tape which selects each transmitter in turn; the rotor of each transmitter being manually rotated until the shutter is at a position corresponding to the desired light intensity for the selected binary-code, the transmitter shaft then being locked.

The circuit arrangement, Fig. 1, can be produced in monolithic integrated form and one such circuit may be provided for each line circuit of the exchange. In operation a ring command signal is supplied on wire 1 to enable a 0-15 binary counter to count a 3À125 Hz clock pulse train supplied on wire T and derived from the mains voltage. Whilst the counter counts from 0-2 gate G6 is enabled to connect a ringing signal to the subscriber's line. For the counting range 3-15 gate G6 is inhibited to provide a pause. The counter is reset from its final state via gate G1 and the sequence then repeats, such that approximately one second bursts of ringing signal separated by approximately 4 second periods of silence are produced. The removal of the command signal trips the ringing.
