Abstract: 1,273,019. Vehicle electrical systems. ACCUMULATORENFABRIK SONNENSCHEIN G.m.b.H. 3 Oct., 1969, No. 48830/69. Heading H2H. [Also in Division G3] An electrical system for a vehicle comprises a D.C. generator 1 supplying a load 6 and also charging a battery 10 by way of a regulator 9, the regulator also being effective to interrupt the charging process when the battery has reached a predetermined voltage and the charging current has dropped below a predetermined value, the positive terminal 11 of the battery 10 being connected to the positive terminal 8 of the load 6 by a thyristor 12 which is conductive when the generator 1 is not generating and non- conductive when the generator is generating. Thus the load 6 is supplied by the battery 10 when the generator is not generating. When the generator 10 is generating a capacitor 13 between gate and cathode of the thyristor is not charged and the thyristor remains non- conductive. When the generator ceases to generate the capacitor 13 receives a charge, thus rendering the thyristor 12 conductive, thus connecting the battery 10 to the load 6. When the generator once more begins to conduct, a capacitor 17 begins to charge, whereupon the thyristor ceases to conduct, thus disconnecting the battery from the load.

Abstract: 1,090,888. Polishing. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Aug. 2, 1966 [Nov. 17, 1965], No. 48950/65. Heading B3D. A process for polishing concave mirrors or reflectors comprises using the mirror or reflector as a container for granular material and rotating and/or vibrating the mirror or reflector so that the granular material acts on the surface thereof. The mirror is initially formed from a sheet 1, Fig. 1, of aluminium which is clamped between members 2a, 2b and stretched over a former 6, the members forming an annular ring 4, Fig. 2, on the mirror. A pair of mirrors are then joined face-to-face with a gasket 10, Fig. 4, between the rings and the space 12 between the mirrors is half-filled with ceramic chippings, cutting compound and water 11. The assembly is rotated about an inclined axis so that a matt surface is formed on the mirrors, a pressure relief valve 10a being provided. After separation, the mirrors are cleaned and degreased which smooths the surface further. The mirror 1a, Fig. 6, is then mounted on a platform 16 which is supported on leaf-springs 15 and reciprocated by an adjustable link 18 driven by an eccentric 19 from an electric motor 17. The platform 16 also carries an electric motor which slowly rotates the mirror as it is reciprocated. The surface of the mirror is treated as it is reciprocated and rotated by coarse coconut granules or hard wood sawdust impregnated with wax and may be further finished by finer coconut granules. A paddle or Archimedean screw may be inserted into the granules to prevent them sticking to the surface of the mirror. A final polishing may be effected by using a small pad of granules with the mirror tilted at an angle of 22¢ degrees. A plastic strippable coat is sprayed on to the mirror and the rim turned off. Finally, the mirror is anodized by immersion in a bath of tri-sodium phosphate and other chemicals, a current of 300 amps. being supplied to the mirror through aluminium studs 7 welded to the back of the mirror.

Abstract: 1,170,768. Discharging molten metal by gaseous pressure. J. S. CAMPBELL. Nov. 9, 1966 [Nov.30, 1965], No.50197/66. Heading F1R. Molten metal is discharged from a container 1 to a nozzle 21 by pressure gas introduced below the level of the liquid from a conduit 23. The gas is supplied at two alternative pressures such that one pressure maintains a ready to pour column having an upper level 29 and the other pressure raises the level to pour level 27 so that liquid is discharged over the lip 17. The pressures are controlled by valves 45, 47 and selected by a solenoid actuated valve 51. The gas may be nitrogen or argon. The actuating gas is also introduced above the liquid levels in the end of the conduit 15 by means of a conduit 57 having a control valve 59; pressure is controlled by a pressure switch 61 which opens a vent valve 65. At the end of a pour the level of liquid is quickly brought to the level 29 by introducing pressure above the liquid level in conduit 15 by closing valve 65 and opening valve 73. The pour cycle may be controlled by a time switch 93. Bubbling of the gas through the molten metal serves to purify it and the inert gas prevents oxidation.

Abstract: 1,250,036. Sorting by gauging. POLYPLASTE H. ROLF SPRANGER K.G. Oct. 16, 1969 [July 15, 1969], No. 50824/69. Heading G1M. Apparatus for testing the accuracy of certain dimensions of plastics parts 1 such as the spring sockets and nozzles used in spraying bottles comprises a turn-table 15 having associated therewith automatic testing stations for testing the dimensions of the parts, an automatic feed to deliver the parts to the turn-table and a number of ejector devices for rejecting unsatisfactory parts, the ejector devices being pneumatically, hydraulically or electrically actuated in response to the operation of time delay relays 28 by signals derived from pneumatic measuring instruments 27 adapted to test the dimensional accuracy of the parts by feelers 26. The parts are fed to holes in the periphery of the turn-table which indexes the parts to the testing stations such as that shown in Fig. 4 which measures the length of the part. A pivoted arm 24 is adjusted in position by a stop screw 25 so that its free end has a position corresponding to an acceptable length for the part 1. If the part has an incorrect length the feeler 26 will be moved upwards or downwards thus causing a signal to be sent to the relay 28 which controls a pneumatic cylinder for operating an ejector in the form of a series of pivoted arms which push the unsatisfactory part through the turn-table and into a collector bin. At a second station, Fig. 5, for testing the diameter of a bore of the part 1 a feeler 31 is pushed into the bore by a number of pivoted arms such as arm 32 actuated by a cam 33. A part having an unsatisfactory bore causes the pneumatic measuring instrument 34 to apply a signal to the relay 35 which operates an ejector device. Other stations are also described for measuring the diameter of the orifice of a nozzle part, for measuring the external diameter of the nozzle part and for testing the leak tightness of the sealing lip of a socket part. At each station cams control the movements of fixing pins for locating the part to be tested and/ or the movements of the feelers which effect the measurement. The cams and the automatic feed which delivers the parts to the turn-table are operated by the motor which indexes the turntable.
