Patent GB-761196-A (GB)
Abstract: 761,196. Automatic control systems. ALU. MINIUM - WALZWERKE SINGEN GES. Sept. 3, 1954 [Sept. 3, 1953], No. 25680/54. Class 38 (4). [Also in Group XXXVI] In a continuous process for oxidizing etched electrode material for electrolytic capacitors, oxidation conditions are varied in dependence on capacity measurements of the material, to compensate for variations in surface roughness. As shown, etched aluminium foil 1 is uncoiled from a spool 2 and passed through electrolytic baths I and II in which it is anodized to make it suitable for the anodes of electrolytic condensers. Separate D.C. potentials (from sources not shown) are applied between the foil and bath electrodes 9 and 10. Variations in capacity between the foil and electrode 12 of an electrolytic measuring bath M influence, in a stage W, an A.C. bridge circuit, the output of which controls, through an electronic amplifier and relays, a reversible servomotor adjusting the field excitation of a D.C. generator in a stage G to vary the potential applied between the foil and electrode 11 of a further anodizing electrolytic bath A so as to compensate for variations in the degree of etching of the metal foil. Foil suitable for producing electrolytic condensers of uniform capacity is thus wound up on spool 5. The following modifications are referred to :-(a) Variation of the speed of the foil instead of the potential applied to an electrolytic bath. (b) An arrangement in which one of the electrolytic baths serves as a combined anodizing and measuring bath. (c) Electrodes of tantalum or iron or sprayed metal.

Patent GB-792713-A (GB)
Abstract: 792,713. Electric indicating systems. GISHOLT MACHINE CO. Sept. 16, 1955 [June 13, 1955], No. 26554/55. Class 40 (1). Apparatus for checking a rotary unbalance testing machine comprises means for simulating an unbalance greater than and smaller than a predetermined value, whereby the first should operate an alarm circuit and the second should not. The unbalance measuring machine comprises a vertical spindle 1 with a platform 2 for supporting the test article, the spindle being mounted in a cradle 3 carried at its corners by straps 4 attached to the machine frame 5. A horizontal rod 6 extends from the cradle 3 carrying a coil 7 in the field of a magnet 8. Unbalance of the test article on platform 2 produces lateral vibrations of cradle 3, rod 6 and coil 7, which are converted to proportional voltages and measured at meter 56, and also produce proportional deflection of the armature 10 of a moving coil instrument unit 9. At a predetermined unbalance voltage the armature 10 touches a contact 11 to energize a relay 13 controlling an audible or visual alarm. Known unbalance conditions are simulated by vibrating the magnet 8 by a rod 15 driven by an A.C. energized coil 16 located in the field of a fixed magnet 17, the amplitude of the A.C. voltage being controlled by relays 50, 52 (not shown), operated in sequence and associated with time delay relays so that when contact 50-1 is closed armature 10 should reach contact 11 or an alarm is indicated, followed by closure of contact 52-1 when armature 10 should not reach contact 11, or the alarm is indicated. A motor 20 normally clamps the cradle 3 between unbalance tests, during which the apparatus is being checked. Specification 790,513 is referred to.
Patent GB-2063217-A (GB)
Title: Liquid metering device
IPC: G01F13/00
Filed: 1979-11-15
Abstract: A device for use in supplying a predetermined volume of liquid comprises an elongate inlet passageway (7, 8) which extends into a cup (9) underneath which is carried a float (15) on a shaft (16). The cup is connected to the passageway via legs (10) so that the cup can move longitudinally relative to the passageway as the float rises and falls. The amount of movement is determined by stops (11, 12) between which the feet (17) of the legs can move. With the float in its lowermost position and with the passageway sealed from the atmosphere above its exit into the container, liquid can flow into the cup until it seals the exit. Thereafter, if the float rises, the cup is moved upwards so that the passageway extends further into the cup until the feet of the legs engage against the upper stop, resulting in displacement from the cup of a predetermined volume of liquid. If the float is lowered to its lowermost position, the liquid seal at the exit of the passageway is broken, further liquid flowing into the cup until the seal is re-established. <IMAGE>

Patent GB-2041079-A (GB)
Title: Internal combustion engines
IPC: F02B19/12
Filed: 1979-12-10
Abstract: Primary combustion air is pumped by a rotary pump 12 into a precombustion chamber 5 through a valved port 9, fuel being added either by a carburettor 13 or injector. Secondary combustion and scavenge air is induced through port 8 by the suction effect of outgoing exhaust gases, or forced by a turbocharger, into the main combustion chamber 4. The pumped primary combustion air allows engine starting without the need for crankcase pumping so that the disadvantages of conventional two- stroke crankshaft and crankcase design can be eliminated to produce a clean two-stroke engine. Retention of the primary charge in the precombustion chamber during scavenging eliminates charge loss to exhaust and uneven running at low loads. <IMAGE>

Title: Lubrication in Metal-working Processes
IPC: B21B45/02
Filed: 1980-08-15
Abstract: During a metal-working operation, e.g. rolling or drawing, a lubricant with electrically charged particles is attracted to the working tool(s) or workpiece by an electric field. The field is generated by creating a D.C. circuit between the tool(s) and workpiece or between the tool(s) and lubricant. In one form, positively charged rollers 15 and 16 are lubricated by an emulsion contained in troughs 19 and 20 containing negative poles 21 and 22. In use, the electric field resulting in the lubricant emulsion causes anionically charged lubricant particles to adhere on the rollers 15 and 16 with the result that increased lubrication is achieved during the rolling operation. The lubricant may be an anion type emulsion (emulsified by triethanolamine oleate with a 10% concentration and average particle size of 5 or 0.9 microns). <IMAGE>
