Patent EP-0005963-A1 (EP)
Inventor: STERLING HENLEY FRANK
IPC: C23C16/04
Filed: 1979-05-24
Abstract: A vitreous material, for example silica is deposited on the inner surface of a tube (11) from the decomposition of a volatile silicon compound in a hot intense inductive plasma material by the application of radio frequency power from a generator (17) via a coupling coil (15) and a matching coil (16). The use of such an inductive plasma feed with gas at a pressure within the range of 0,1 to 50 Torr, provides fusion of the deposited silica on the inner surface of the tube, the outer surface of the tube (11) being water cooled. The process may be employed in the production of preform tubes for step or graded index optical fibre manufacture.

Abstract: ot coke 3 expelled from a coking chamber is conveyed in a quenching car 2 to a quenching tower 4 past an infra-red detector 6 which provides a signal to initiate supply of the quenching water. It is a problem to control the amount of quenching water supplied to achieve adequate quenching without adding excess humidity. To solve this, the detector produces an analogue signal dependent on the surface temperature of the passing coke, and the duration of supply of quenching water is determined from this signal. The signal may also be used to control variation of the degree of quenching at different parts of the car and also to control the heating of the coking chamber.

Abstract: A method and apparatus for continuously controlling of the cleaning of suede and leather garments comprising a plurality of tanks (18) each containing a slightly different cleaning fluid (16). Each of the tanks is preferably continuously filtered for soluble impurities and is selectively communicable to a washing device (10) into which is introduced the garments. An additional amount of cleaning fluid is added to the wash device approximately equal in weight to the weight of the garments to be washed. A further additional amount of cleaning fluid is added which is approximately proportional to the weight of the garments being washed. After washing, the reamaining liquid is returned to the original tank. In this manner the tank will be refilled to the original level and will overflow through an overflow aperture in an amount approximately equal to the further added cleaning liquid. The overflowed cleaning liquid will then be gathered in a sump tank (62) and be pumped to a holding tank (64) and subsequently be distilled to remove pure solvent therefrom. This solvent will pass through a reclaiming line (44) to a position where it may be mixed with cleaning additives (52) in the proper amount in order to match one of the cleaning liquids within one of the plurality of tanks (18). This new mixture will now be added to the wash cylinder (10) in an amount equal to or proportional to the weight of the garments therein and as such the cycle will be completed. In this fashion, a method and apparatus is disclosed for continuously maintaining the desired condition of the cleaning liquids when washing leather and suede garments.

Abstract: A method for attenuating fluid flow passing through a valve (1) provided with a flow passage (4), in which a closure member (2) is rotatably positioned whereby attenuating of the fluid flow occurs in both flow directions mainly in the passage in the closure member (2) or in a bore (3) passing through the closure member (2) so that attenuating effect is increased as the valve is being closed and is reduced as the closure member (2) is rotated towards the open position. In the passage in or passing through the closure member (2) the length of the fluid flow path is increased and the direction of the fluid flow is alternated. The more the valve is being closed, the fluid flow path in the bore (3) in the closure member (2) becomes longer and, correspondingly, the higher becomes the number of changes in direction of the fluid flow within the range of the bore (3) in the closure member (2).

Abstract: The present invention provides high NSI dry vegetable protein isolates which may be effectively utilized to replace egg albumin and/or milk caseinates in food recipes. The isolates are characterized as having an NSI of at least 90, substantially free from vegetable protein hydrolyzates, capable of forming insoluble heat-set gels and having aqueous Brookfield viscosities substantially lower than those which are obtained from conventional undigested vegetable protein hydrolyzates. The relatively neutral pH extraction conditions in the presence of sulphurous ions, coupled with its recovery without chemically or enzymatically hydrolyzing the protein constituents affords an effective method for manufacturing these unique isolate products. The isolates may be used to directly replace either casein or egg albumin in a wide variety of food recipes.
