Title: A Starting Circuit for a Single-Phase Asynchronous Motor
IPC: H02P1/42
Filed: 1968-06-18
Abstract: 1,183,294. Control of A.C. motors. DANFOSS A.S. 18 June, 1968 [6 July, 1967], No. 28911/68. Heading H2J. The auxiliary winding 3 of an asynchronous motor is energized via a symmetrical controlled semi-conductor device (Triac) 7 in series with an ohmic resistor 8 (which may provide the necessary phase splitting), the control electrode 11 being supplied via a PTC resistor 10. At switch-on, the PTC resistor 10 passes sufficient current to trigger device 7 on, but the temperature and resistance of 10 rises until a point is reached when the current through it is insufficient to trigger 7 and the auxiliary winding is then effectively disconnected. A small current continues to flow through 10 thereby maintaining its temperature. The PTC resistor 10 is heated either by its own current, by resistor 8, by a separate resistor in series with the main winding or by the heat produced by the motor. Because of the time required for 10 to cool, too frequent starts are prevented.

Title: Improvements in and relating to the manufacture of glutamic acid and salts thereof
IPC: B30B3/04
Filed: 1924-12-03
Abstract: 248,453. Ikeda, K. Dec. 3, 1924. Glutamic acid and its salts are obtained from schlempe, a bye-product of beet-molasses, by hydrolyzing it and converting the glutannic acid into its sparingly soluble calcium salt. The schlempe. liquor may be treated with excess of lime to produce the desired calcium salt in one operation, or it may first be hydrolyzed with a mineral acid such as hydrochloric or sulphuric acids, and the neutralized solution treated with lime. Alternatively, the sohlempe is treated with hydrochloric acid, and after filtering off humus-like products, crystalline potassium chloride and betaine hydrochloride, the concentrated filtrate, is further treated with hydrochloric acid to form glutamic acid hydrochloride, which is dissolved in water and digested with excess of lime. Addition of alcohol or of a soluble calcium salt and ammonia facilitates the separation of the sparingly soluble calcium, salt. This salt may be treated with mineral acids to obtain glutamic acid, or by the addition of acid salts formed by the combination of alkalis and acids whose neutral calcium salts are insoluble, soluble alkali glutamates may be obtained. The soluble calcium glutamate may be. obtained by treating the sparingly soluble calcium salt with carbon dioxide in presence of water. Specifications 9440/09 and 12737/11 are referred to.

Hot plastic material is forced through a nozzle 1, Fig. 1, into a mould 2 having a base 6, core 3 and article-ejecting mechanism 4, to produce a preform 5. The base 6 then descends from the Fig. 1 position to the Fig. 2 position. and simultaneously the mechanism 4 ejects the preform from mould 2, the speed of descent of base 6 being substantially the same as the speed of ejection of the preform. A second mould consisting of two parts 7 is then closed about the base 6, as shown in Fig. 2, and a pipe 8 is introduced from core 3 into the second mould. Compressed air or other gas or vapour or liquid is then blown through pipe 8 to expand the preform into contact with the walls of the second mould to produce, e.g., a bottle. To preclude sticking of the bottle to the second mould, the latter may be colder than the first mould. There may be a plurality of second moulds working in conjunction with the first mould. During ejection of the preform from the first mould to the second, gas may be blown into the preform to prevent shrinkage or warping, the pressure of the gas being increased to the blowing pressure when the second mould has been closed. Ejection into the second mould may be effected by gas pressure. In a modification the material is introduced into the first mould in a cold or slightly heated condition, then heated to working temperature, then pressed into preform shape by member 4, then ejected by member 4. Mould base 6 may contain heating means 9 to prevent premature solidification of the lower part of the preform. The material used may be polyvinyls, polyurethanes, polyamides, polyesters, polyethylene or cellulose derivatives.
