Title: Improvements in and relating to apparatus and methods for purifying water
IPC: A23L2/12
Filed: 1943-10-04
Abstract: 568,553. Ice - making. BRITISHTHOMSON-HOUSTON CO., Ltd. Oct. 4, 1943, No. 16216. Convention date, Oct. 5, 1942. [Class 29] [Also in Group I] The solvent component of a solution is obtained in a substantially pure form by means of a freezing chamber having a smooth domeshaped surface with dependent vertical sides, the solution being forced as a jet against the upper (dome) part of such surface and draining away uniformly over such surface and the surface being maintained at an ice-forming temperature. The jet velocity should be sufficiently high to prevent exclusion of the solute in the frozen solvent component. The invention can be used for the purification of sea water and for the concentration of fruit juices or milk by the removal of water. As shown, a dome piece 31 is housed in a heatinsulated chamber 32 having salt water and purified water compartments 38, 51, from the former of which salt water is drawn by a pump 42 for delivery by a nozzle 49 directing the salt water upwardly against the top of the dome piece 31. A refrigeration compressor 34 and condenser 35 supply a refrigerating coil 33 around the dome, whereby the solvent component is frozen on to the interior of the dome piece 31 and continuously washed by the salt water to prevent any salt being occluded in the ice so formed ; the wash returns to the salt water compartment 38. A timing switch device 53, slowly rotated by a single-phase synchronous motor 57 periodically cuts out the pump motor 43 &c. refrigeration motor 36 and inserts a heating coil 52 for the dome piece, whereby the block of ice is released to fall on a grid 61 and so passes to the pure water compartment 51. Operation of the apparatus is stopped when either a switch 66 is opened by a float 64 or a switch 68 is operated by a swinging entrance flap 62 to the pure water compartment 51 being held open by blocks of ice. A domestic refrigerator may be adapted for the purpose by providing a dome piece to be attached to the unused evaporator unit, e.g. by spring clips and by freezing of water, and a liquid tank with pump and spraying nozzle, Fig. 1 (not shown).

Title: Extracts of parts of plants of the genus aesculus
Inventor: BOSSE JOACHIM
IPC: C07H15/256
Filed: 1956-05-28
Abstract: A saponin free extract of plants of the genus Aesculus, e.g the horse-chestnut tree (Aesculus hippocastanum), which can be injected without haemolytic effects, is prepared from a saponin containing extract of the horse-chestnut tree by removing the saponins without removing the other substances by (a) treatment with finely divided solid cholesteral, which forms an addition compound insoluble in the extraction solvent, or (b) extraction with a water-immiscible solvent, e.g. chloroform, a halogen containing hydrocarbon, an aliphatic alcohol containing not more than 8 C. atoms, e.g. amyl alcohol, or a mixture thereof.  The cholesterol may be in the form of an aqueous suspension or emulsion and is preferably used in excess. It is preferred to carry out the reaction at elevated temperature while the extraction solvent is continuously being removed in vacuo. The precipitate of saponin-cholesterol is removed and the cholesterol may be recovered for re-use by treatment with glacial acetic acid or extraction with trichlorethylene.  In the extraction process (b), the pH of the extract is reduced to below pH 4.5, and preferably 1 to 3, by acid especially hydrochloric and after the removal of the saponin solution, the residual extract is adjusted to pH 6.0 by means of sodium hydroxide.  The extract so produced contains, inter alia, and when suitably diluted with water may be injected.  It is preferred to extract an aqueous alcoholic solution of horse-chestnut seeds containing not more than 50% alcohol, and especially 36% ethyl alcohol, with chloroform. Specification 820,787 is referred to.

Title: Improvements in and relating to regulators actuated by fluid pressure
IPC: G05D16/16
Filed: 1928-06-07
Abstract: 291,764. Canada Sugar Refining Co., Ltd., (Assignees of Wettstein, F. A.). June 8, 1927, [Convention date]. Regulation, automatic.-Relates to fluid pressure actuated regulators, primarily intended for automatic fluid pressure regulating valves, but applicable also for regulating other physical conditions, such as electrical voltage by means of a rheostat, these regulators being of the type provided with two fluid-pressure relays arranged in series, the first relay acting as the impulse receiver which, in the case of voltage regulation is operated by a solenoid, and the second relay as an amplifier which may react backwards on the first relay. Fig. 1 shows a pressure-reducing valve in which the pressure in the main beyond the valve 1 communicates through a conduit 4 with the first relay comprising a corrugated diaphragm 5 controlling a valve 11 controlling escape of the control fluid (e.g. oil) along conduits 8, 10 from the upper side of the differential piston 17 of the second relay which includes a pilot valve 18. The pressure fluid for actuation of the reducing valve (e.g. oil) is supplied by the conduit 20, through the pilot valve 18, and by the conduit 21 to the operating piston 25 of the main valve; a bye-pass from the conduit 21 leads to the differential chamber 22 from which fluid can escape through recesses 27 which are cut through the circumferential ribs 28 and are arranged alternately on opposite sides of the piston. A reduction of pressure in the outlet 3 causes movement of the diaphragm and throttling at the first relay valve 11, so that the pressure in the chamber 19 increases and forces down the piston 17 and opens the pilot valve 18, allowing an increased supply of the control fluid from the conduit 20 to pass to the piston 25 to open the main valve; the increased control pressure supply also passes to the differential chamber 22 and moves back the piston 17 and the valve 18 to throttle the passage thereby providing a fluid-pressure return-motion arrangement which prevents over-regulation or hunting. The pre-determined reduced pressure in the outlet 3 can be adjusted by operating the hand wheel 15, which alters the position of the sleeve 14 and the valve seating 13 in relation to the first-relay valve 11. The second relay can be operated manually in an emergency by the handle 31 and screwed spindle. The main valve is also operable manually by a bevel gearing and screw arrangement, as shown. A modification is described in which an electric motor running at constant speed operates a pump to supply the control pressure fluid.
