Title: Means for operating auxiliary machinery on ship-board
IPC: B63B21/16
Filed: 1919-07-11
Abstract: 148,687. Poole, W. J. July 11, 1919. Feed-water, heating.-Relates to motor power plants for operating auxiliary machines on ships, in particular to the type of plant in which electric motors are connected to bus-bars fed by the dynamos driven by the engines. According to the invention one dynamo is driven by the main turbine and another dynamo by the auxiliary turbine or reciprocating engine, which also heats the feed-water supply for the main engine, and means are provided for transferring the load from the main engine to the auxiliary engine and vice versa in accordance with variations in the temperature of the water supply. Figs. 1 and 2 show one arrangement for carrying the invention.into effect. In this form the alteration of load is brought about by rheostats A2, D2, which are connected in the field circuits of the respective dynamos A, D. A thermostat L4, responsive to deviations from the mean temperature of the feed-heater H acts by vapour pressure upon a piston L1 and is opposed by a spring L5. The movements thus produced are communicated by a rack L to rheostat arms A3, D3, which add or subtract resistance to or from the dynamo fields A1, D1, thus varying the relative electrical loads imposed upon the engines driving the dynamos A and D, while the total electrical load is not affected. In a modified arrangement, a thermal relay controls a reversible motor which actuates rheostats. In a modification which does not employ rheostats, the variation of load is effected by thermostatic control of the steam valve of the auxiliary engine.

Title: The production of multi-coloured artificial cellulosic materials in the form of sheets, bands or films
IPC: D01D1/06
Filed: 1932-06-21
Abstract: Multi-coloured sheets, bands, or films are obtained by heterogeneous colouration of aqueous cellulosic solutions followed by regeneration or coagulation in known manner.  The film-forming solution may be viscose, or a solution of cellulose in cuprammonium, thiocyanate, or zinc chloride solution.  The films may be transparent or if fillers such as kaolin, blanc fixe, or metallic powders are incorporated in the solutions, they may be translucent or opaque.  The cellulose solution may be divided into a number of equal or unequal portions which are separately dyed or coloured and then associated together to any desired degree of partial blending followed by regeneration.  If desired one or more coloured cellulosic solutions may be associated with an uncoloured cellulosic solution.  In an example, a number of portions of a viscose solution are separately impregnated uniformly with colour and fed independently to an extruding or pouring device at a number of positions throughout its length in such manner that a degree of diffusion of the variously coloured portions of viscose takes place therein.  The solution is extruded in the form of a heterogeneously coloured sheet into a regenerating or coagulating bath.  In another example, a colourless or uniformly coloured viscose solution is heterogeneously coloured in the extruding device by means of dyes, either as such or in the form of solutions, which are fed at various positions immediately prior to the passage of the viscose through the shaped aperture.  Dyestuffs which may be used are benzo-direct dyes, vat dyes such as indanthrene, pigment dyes, acid dyes such as tartrazine and disulphine naphthalene, chlorazol, thional, and water soluble anthraquinone dyes.  In cases where the dyestuff is discoloured by the cellulosic solution such as viscose, or by the mineral acids or other substances employed in the regenerating baths, the colour may be restored by treatment with a neutralizing or oxidizing bath.

Title: A process of delaying haze formation in beverages
Inventor: BERNTSSON NILS SVANTE
IPC: C12H1/056
Filed: 1956-06-08
Abstract: Haze formation in beverages, e.g. malt beverages, fruit juices and wines, is prevented by the addition of at least one gram of polyvinyl pyrrolidone per hectolitre of beverage and in any case in an excess quantity of at least 50% over the quantity of 0 to about 8 grams per hectolitre necessary for the maximum precipitation of the haze-forming constituents, e.g. 5 to 50 grams per hectolitre; the zero value for maximum precipitation relates to cases in which the average molecular weight of the polyvinyl pyrrolidone is below about 15,000 or the kind or quality of the beverage does not yield any precipitate.  The polyvinyl pyrrolidone may be added in powder form or as a solution, during storage of the beverage or before, during or after the clarification prior to bottling.  In cases where a precipitate is formed, the excess quantity of polyvinyl pyrrolidone may be added after removal of the precipitate formed by addition of the quantity for maximum precipitation, or the total amount may be added directly, the precipitate initially formed subsequently redissolving.  Examples relate to the treatment of various beers. Specification 736,565 is referred to.
