Title: Improvements in or relating to the separation of carbonic acid and other vapours of low boiling point from gases
IPC: F22B37/26
Filed: 1930-08-07
Abstract: 355,923. Separating gases by selective freezing. FRNKL, M., 234, Ulmerstrasse, Augsburg, Germany. Aug. 7, 1930, No. 23671. Convention date, Aug. 19, 1929. [Class 8 (ii).] Carbon dioxide &c. are removed from gases, such e.g. as blast furnace gases, by passing these gases and air &c. alternately and oppositely through cold accumulators f<1> . . f<4>, in which the carbon dioxide &c. is frozen out from the gases and resublimed and carried away by the air. Gas entering by a reversible valve a<1> passes through an accumulator f<1> where it deposits moisture and carbon dioxide, and expands in a motor cl, from which it flows out through an accumulator f<3>; simultaneously air is introduced through the accumulator f<4> and after expansion in the motor c<2> passes out through the accumulator f<2>. On reversing the valves a<1>, a<2>, b<1>, b<2> gas is supplied through accumulator f <2> and escapes through accumulator f<4> and air is supplied through accumulator f and escapes through accumulator f The air escaping takes up the carbon dioxide and moisture deposited by the previous gas flow, and the gas escaping takes up the moisture deposited by previous air flow. In a modification, the air only is expanded, the gas passing through the accumulators at the same pressure. In a further modification, one pair of accumulators only is employed, the air and gas supply being intermittent.

Abstract: 906,910. Hot-water supply systems. HOARE, C. H. Oct. 10, 1960 [July 11, 1959], No. 23896/59. Class 64 (1). In a hot-water tank for use in a domestic supply system, having flow and return connections a and a<SP>1</SP> from and to a boiler (not shown), a baffle B in the form of an inverted truncated semi-cone is attached to one wall of the tank vertically above the opening of the flow pipe a, the hot-water draw-off pipe a<SP>2</SP> opening into the space enclosed by the baffle and the latter being open at its upper end and closed at its lower end by a plate b having perforations b<SP>1</SP>. Hot water entering the tank from the boiler rises through the baffle to the upper layers of storage water. In the event of failure of the coldwater supply, water is drawn off from the tank until the level falls to the top of the baffle and thereafter water flows into the baffle through the perforations b<SP>1</SP> to be drawn off through the pipe a<SP>2</SP> until the level drops to the draw-off point. In a modification, Fig. 5, the baffle comprises two truncated cones B and B1, one inverted, joined at their narrowest parts by a perforated plate through which the upper end of the draw-off pipe a<SP>2</SP> projects. The flow pipe a is disposed below the cone B1. If the supply of cold water supplied to the cylinder A1 from a cistern C fails, hot water can still be drawn off through the pipe a<SP>2</SP> flowing thereto firstly down through the cone B and then upwardly through the cone B1. Normally and when no hot water is being drawn off the hot water from the boiler entering the cylinder through the pipe a flows directly to the upper part of the cylinder through the baffle cones. In a further modification, Fig. 6 (not shown), the baffle consists of an openended or perforated tube surrounding the upper end of and extending above the draw-off pipe.

Title: Improvements in and relating to the manufacture of alcohol from molasses and the like
IPC: C12P7/06
Filed: 1930-08-15
Abstract: Alcohol is produced by subjecting molasses and the like to fermentation with yeast of the character of Steinberg yeast, port wine yeast, or Burgundy wine yeast.  The yeast is first grown in a medium containing phosphates and nitrogenous bodies such as di-ammonium phosphate and urea, and after some time a sulphite is added and the growth of the yeast allowed to continue, then a proportion of molasses is added after which the yeast is added to the molasses to be fermented.  The molasses may be preliminarily treated with sulphurous acid or a sulphite to kill the ferments contained in the molasses, eliminate the substances which result in bad smelling alcohol and hydrolyse the saecharates present.

Abstract: 1,186,947. Apparatus for treating textiles. ROA CORPORATION. 23 May, 1968 [23 May, 1967], No. 24630/68. Heading D1L. [Also in Division G2] A liquid dispenser for applying a liquid developer 12 (Fig. 3) to a surface bearing a latent electrophotographic image comprises a container 10 having a reservoir, an elongated manifold 44 positioned on the top wall of the reservoir and having a feed opening 42 communicating with the exterior of the container, a pump 64 Fig. 2 for forcing liquid in the container into the manifold and out through the feed opening, a trough 47 surrounding the manifold for collecting excess liquid flowing through the feed opening, and a return passage 60, 62 from the trough to the reservoir. A rotatable magnetic member- 80 is magnetically coupled to impeller 64, and forces the liquid through channels 72, 74, 76 to manifold 48, glass or stainless steel wool 116 being disposed in the manifold to control and distribute the liquid. A standpipe 132 communicating with a drain 138 serves to maintain a constant pressure in the liquid supply, to allow bubbles generated by the pump to escape and to allow a greater volume flow through the pump thereby assisting mixing of the developer. A latent image is formed on a photoconductive surface 14 of a paper web 16 by contact with a cathode-ray tube face plate 106, an initial charge being given from corona discharge devices 100, 102. The web passes over a roller 46 so as to be slightly spaced from the feed opening 42 defined by two parallel spaced apart developing electrodes 52, 54. Return passages 60, 62 extend towards the bottom of the reservoir to minimise oxydation of the developer through contact with the air. The container is designed as a unit to permit portability and is therefore fully sealed, the developer being introduced into the container through a threaded aperture (34) (Fig. 6, not shown) which is then sealed with a screw plug (36). A vent passage (38) is located near the aperture (34). The feed opening and trough may be sealed by a plastic strip or adhesive tape during transit.

Method of making a luminescent screen of a cathode-ray tube comprises preparing a water suspension of basic magnesium carbonate, silicic acid and manganese carbonate in proportions which will yield a magnesium metasilicate containing 0.5 per cent by weight of manganese when fired, milling the suspension, drying the milled material at about 110‹ C., adding 10 per cent by weight of potassium chloride to the dried mixture, intimately mixing by milling, firing the resulting dry powder mixture at a temperature of about 1100‹ C., milling the fired mass in a rod mill with water as a vehicle, drying the milled material and selecting therefrom particles passing through a 325-mesh sieve, and applying the selected particles to a cathode-ray tube face by spraying, air-settling, liquid-settling or lacquer flowing. The selected particles can be suspended in an aqueous 1 per cent solution of potassium silicate and the suspension spilled through the neck 5 of the cathode-ray tube bulb 3, Fig. 3, up to the level L-L of the conical part 6, the screen 8 being formed on window 4 by the particles settling from the suspension 9 and the excess liquid being siphoned off. When a graphite coating 7 is applied to a part of neck 5 and of conical part 6 of bulb 3 after the screening operation the tube may have a pre-bake of ¢ hour at 350‹ C. with a flow of dry air through the coated bulb followed by an exhaust bake of ¢ hour at 330‹ C. When a coating of silver has been applied and processed previous to the screening operation in which a non- aqueous medium without auxiliary binder is used, the pre-baking step may be eliminated. The luminescent screen has a peak luminescent emission in the red end of the spectrum and a decay rate characterized by a " slope 1/e " time constant of about 70 milliseconds. The characteristics of cadmium silicate are referred to.
