Title: Improvements in or relating to electrical power supply regulation
IPC: G05F1/52
Filed: 1946-07-06
Abstract: 622,230. Automatic voltage control systems; automatic regulation; rectifying. STANDARD TELEPHONES & CABLES, Ltd. July 6, 1946, No. 20245. Convention date, July 9, 1945. [Classes 38 (ii) and 38 (iv)] A voltage regulated D.C. power supply is interconnected with a second, otherwise unregulated power supply so as to improve the regulation of the second supply. Gas-filled tetrodes 6, 7, forming in push-pull a full-wave rectifier, have their control grids connected through a 90 degrees phase-shifting network 16 to one winding 13 on the mains transformer. The firing point of the valves is determined by the bias on the centre tap of winders 13, this bias being the resultant of the voltage stabilized output of rectifier 18 in opposition to a portion of the power output tapped off at 21. A second rectified power supply 2, having an output voltage greater than that of the regulated supply, is coupled thereto by a resistor 37 so that a part of the load 32 is supplied through this resistor. A change in the output voltage of 2 tends to change the voltage at 23. The resulting automatic adjustment of the regulated supply alters the load on circuit 2 and thus by altering the voltage drop across the rectifier tends to restore the output voltage to its former value. Relay 35, energized by circuit 2 through valve 34, provides delayed switching of the output of rectifiers 6, 7.

Filed: 1967-05-02
Abstract: 1,115,420. Orientating eggs. AVIOLANDA MAATSCHAPPIJ VOOR VLIEGTUIGBOUW N.V. 2 May, 1967 [3 May, 1966], No. 20363/67. Headings B8A and B8S. An egg aligning device comprises two walls 10, 11, the distance between the top edges 10a, 11a being greater and the distance between the bottom edges being smaller than the maximum transverse diameter of the egg 12 and is characterized in that the walls 10, 11 converge in the horizontal direction, an egg introduced into the device automatically occupying a position such that its pointed end points in a particular direction. If the egg 12 is deposited in a position shown by chain lines in the aligning space 13 between the walls 10, 11 it bears via its places of contact S against the walls 10, 11. Since the centre of gravity Z is higher in this position (see Fig. 2) the egg 12 tilts through a vertical position 12<SP>1</SP> into the solid line position 12<SP>11</SP> where the centre of gravity Z<SP>11</SP> is to the right of the places of contact S<SP>11</SP> and the position of the egg 12 is stable with its pointed end 14<SP>11</SP> to the right. If an egg is directly deposited in the aligning space in the position 12<SP>11</SP> it remains in that position. An abnormal egg (not shown) occupies a somewhat inclined position, but is otherwise aligned. Fig. 6 illustrates a lifting device 17 associated with the aligning device wherein a bowl-shaped member 20 on a connecting rod 18 coupled to conveyer belts 15, 16 receives eggs 12 singly from belt 15, deposits them for alignment between the walls 10, 11 and discharges the eggs 12 to the belt 16. Fig. 8 illustrates a similar lifting device 21 receiving eggs 12 singly from a feed conveyer 30 with rollers 29 and feeding them after alignment to a removal conveyer 31 with rollers 33. A number of the aligning devices with feed and removal conveyers may be arranged in parallel, Fig. 9 (not shown), and the aligned eggs carried to an inspection station for sorting and packing.

Title: Improvements in cleansing compositions
Filed: 1945-08-09
Abstract: Cleansing compositions, particularly powders for the cleansing of artificial dentures, comprise an alkali metal percarbonate, an alkaline material and an activating agent, in such proportions that a dilute, e.g., 2 per cent. aqueous solution of the composition has a pH of 9.0 to 11.5 and preferably 10.0 to 10.6. The alkaline material may be a buffer, e.g., a mixture of anhydrous sodium carbonate and sodium bicarbonate, generally in a ratio of the order of 4 to 1, the activating agent may be water-soluble alkali-stable, and coated with a material capable of preventing interaction between the percarbonate and the activating agent during storage of the composition, e.g., an organic carboxylic acid not more than slightly soluble in water but capable of forming water-soluble salts with alkaline materials. The activating agent may comprise a complex of a hydroxy carboxylic organic acid with a metal which is capable of existing in at least two states of oxidation, e.g., a cobalto-gluconate complex.  The composition may include alkali metal soaps or other wetting agents, a dye of such a character that it will be rendered p  substantially colourless in an aqueous solution of the composition within a predetermined period, e.g., 10 to 30 minutes, indicating that the cleansing of the denture by liberation of oxygen from the percarbonate has been completed, and an alkali metal phosphate of a type which prevents the precipitation of calcium, magnesium and iron compounds from the solution and assists in the removal of calculo-like deposits from the dentures, e.g., sodium hexametaphosphate.  The range of proportions of the ingredients may be: sodium percarbonate 15-40 per cent.; anhydrous sodium carbonate 35-40 per cent.; sodium bicarbonate 8-12 per cent.; activating agent 1-15 per cent; sodium hexametaphosphate 1-5 per cent.; dye and wetting agent minor amounts; anhydrous sodium sulphate (filler or diluent)-2 per cent. to 35 per cent. Methods for preparing coated cobalt complex activating agents are described.  About 10 to 30 minutes immersion of the denture in a dilute aqueous solution of the composition suffice for cleansing.
