Abstract: 1,267,216. Capacitors &c. INTERNATIONAL BUSINESS MACHINES CORP. 28 July, 1969 [5 Aug., 1968], No. 37767/69. Heading HlH. In a process for mass-producing linear ferrite cores which includes steps of batch pressing and sintering raw powdered ferrite, a batch of cores is mechanically agitated at ultrasonic frequency, in a medium in which the cores are permitted to abrasively collide with each other at random, for a time sufficient to reduce magnetostrictive ringing as ascertained from measurements made on a sampling of the cores prior to agitation. The medium may be an alcoholic suspension of alumina particles contained in a beaker placed in an ultrasonically vibrating tank. The treated cores are removed from the medium magnetically, and air-dried. Preparation of cores from ZnO, NiCO 3  and Fe 2 O 3  is described, the process involving granulating ferrite powder and polyvinyl alcohol binder, moulding the granules, and sintering the resulting cores. Cores of Mn 0 . 8 Zn 0 . 2 Fe 2 O 3  are also specified.

Filed: 1969-04-10
Abstract: 1301852 Battery charging circuits SEVCON ENG Ltd 9 April 1970 [10 April 1969] 18486/69 Heading H2H [Also in Division H3]  A circuit for charging a battery 27 comprises a thyristor 13, an inductor 11 and a control circuit for controlling the switching of the thyristor so that during conductive periods of the thyristor energy is stored in the inductor as the current through the inductor increases, the stored energy being supplied to the battery during non-conductive periods of the thyristor. Assuming a thyristor 19 to be switched on and consequently the thyristor 13 to be switched off, a relatively low current flows in the output circuit of a rectifier 8 supplied by a current transformer 7. A transistor 41 connected via a Zener diode 56 to the tapping point of a resistor 57 is therfore non-conductive but the increase in the voltage across a commutating capacitor 15 causes the voltage at the anode of the thyristor 13 to rise thus switching on the transistor 41 via a differentiating circuit 69, 70. When the anode voltage reaches a maximum the transistor 41 is switched off and a capacitor 43 is charged until a shockley diode 45 breaks down thus switching on the thyristor 13 and switching off the thyristor 19. The current in the inductor 11 in the output circuit of a rectifier 9 increases, the voltage across the resistor 57 also increasing due to the increased current through the transformer 7. The Zener diode 56 therefore breaks down causing the transistor 41 to conduct and the gate pulse applied to the thyristor 13 to be terminated. The increased voltage across the resistor 57 causes a transistor 79 to enable the break down voltage of a diode 87 to be exceeded so that the thyristor 19 is switched on and the thyristor 13 is switched off. The energy stored in the inductor 11 therefore charges the battery via a diode 25. A circuit including resistors 109, 111 and a diode 113 prevents the thyristor 13 being switched off in the event of the battery having a lower voltage than the rectifier supply voltage. Transistors or silicon controlled switches may be used instead of the thyristors.

Each bit of a stored descriptor which is unequal to the corresponding bit in the incoming signals switches in a capacitor between the path corresponding to the descriptor and a power line. A square wave applied to the path is converted into a ramp of slope depending on the number of such capacitors switched in. The first ramp to reach a threshold indicates the descriptor closest to the incoming signals, to read a corresponding name from the further store to an output register. On initial loading of the stores, loading is inhibited when the name (to be loaded) agrees with the contents of the output register.

Abstract: 1352846 Transfer devices ALFRED HERBERT Ltd 19 April 1971 [10 April 1970] 17118/70 Headings B3T and B3B A lathe having a chuck transfer device comprises a bed, a head stock 10 with a driven work holding spindle 11 and a dummy spindle 28 on which a chuck can be located and transfer means 31 by which the chuck from the dummy spindle is transferred to the driven work spindle whereby work mounted in the chuck can be machined by a cutting tool mounted on a movable tool carrier on the lathe bed. In the embodiment described, two chucks 12 and 42 on the dummy and work spindles respectively are changed by indexing the transfer means 31 which is supported on a shaft 32 parallel to the axes of the work and dummy spindles. The chucks are first released from their respective spindles by actuation key units 16 and 30 which rotate threaded sleeves 13 in the respective chucks to unscrew the chucks from the spindles and disengage the toothed connections 18 and 19 between the spindles and chucks. The indexing head carries a plurality of hydraulically actuated plungers 56 which, upon release of the chucks from their respective spindles, are actuated to engage in a groove 57 around the periphery of each chuck to clamp it in the transfer means 31. When the released chucks are clamped in the transfer means 31 the means is displaced axially with its shaft 32 by hydraulic means 41 to permit clearance between the spindles and chucks for subsequent indexing of the transfer means 31 by hydraulic actuation of a rack 39 and pinion 40 on the end of the shaft 32. When the indexing has taken place the shaft is moved axially to engage the toothed couplings between each chuck and its spindle and the keys 16 and 30 are operated to screw the chuck sleeves 13 on to the spindles and hence accurately clamp and locate the chucks on the spindles. The incorporation of a transfer device as described permits machining to be effected on a workpiece in the work spindle whilst a fresh workpiece can be located in the chuck on the dummy spindle and whereby a succession of workpieces can be machined.
