Abstract: 1395194 Heat pumps; space heaters or coolers MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 5 Sept 1972 [6 Sept 1971 8 Sept 1971 20 Sept 1971] 41113/72 Headings F4H and F4V A heat pump system air conditioner comprises a refrigerant compressor C, a refrigerant flow reversal valve 11, a gas tube 12, an indoor heat exchanger or coil 13, a combined check valve and expansion valve 25 an outdoor heat exchanger 15 and a suction gas tube 14 connected in the order named, and further comprising means for feeding a portion of the refrigerant liquid leaving the indoor heat exchanger 13 back to its inlet via a heater 33 to increase the heating effect of the heat exchanger at start-up or when the outside temperature is low. The liquid is led from a receiver 23 by a pump 32 to the heater which comprises an exchanger having a heat exchange coil (not shown) surrounded by a heat accumulating medium, e.g. water, and is conducted by by-pass tubes 35, 37 and a valve 36 to the tube 12. During the cooling cycle flow through the by-pass and heater 33 is prevented by closure of the valve 36 and flow of refrigerant through the system is reversed, reversal of flow also achieves hot gas defrosting of the outdoor heat exchanger coil 15 when operating as a condenser coil, the condensed refrigerant from the coil 15 passing through the valve 25 into the receiver 23 for passage through the heat exchanger 33 for evaporation by the heat from the heat accumulating medium, and then through tubes 35, 37, valve 37, tube 12 and the reversal valve 11 to an accumulator (not shown) and suction gas tube 28 into the compressor C. An ejector means may be provided in the gas tube for ejecting the refrigerant liquid flowing from the receiver into the refrigerant gas flowing from the compressor to the indoor coil and the heating means in the heat exchanger 33 may be electrical or formed as a burner. The tapped-off portion of refrigerant leaving the indoor heat exchanger may be mixed with the refrigerent stream passing to the indoor heat exchanger and the mixture passed through the heat exchanger 33. Air to be heated or cooled is circulated over the indoor and outdoor heat exchangers by fans, and in a further embodiment the indoor heat exchanger comprises two coils, one acting as an evaporator and the other as a condenser to achieve dehumidification of the air flowing thereover.

Title: Blood coagulation and separation
IPC: B04B5/02
Filed: 1975-10-09
Abstract: 1513806 Centrifuging blood CORNING GLASS WORKS 9 Oct 1975 [7 Nov 1974] 41407/75 Heading B2P In a method of separating blood into lighter and heavier phases, a vessel is provided with a quantity of coagulation-enhancing particles of a material selected from a group of siliceous substances including glass, kaolin, bentonite, hydrated aluminium silicate and diatomaceous silica, and is supplied with blood the particles having a size and density such that they are readily suspended throughout the blood without external agitation and remain so suspended until coagulation of the blood is complete and the mixture of blood and particles is centrifuged to separate the mixture into a lighter phase consisting of serum and a heavier phase consisting of cellular and fibrillar matter and the coagulation-enhancing particles. The vessel may be in the form of a glass of plastics tube fitted with a pierceable closure through which blood may be siphoned into the tube by venipuncture with a double-ended needle. The coagulation-enhancing particles 20, Fig. 4, may be applied to the interior surface 34 of a cavity 33 within a member 32 which is initially placed in separating gel 30 positioned at the closed end of the tube. As blood is supplied to the tube the particles 20 become suspended in it and upon application of centrifugal force, are precipitated with the heavier phase toward the closed end of the vessel and away from the lighter phase which is moved toward the open end. The gel 30 is forced upwardly by the member 32 to partition the separated lighter and heavier phases. The coagulation-enhancing particles may be prepared by grinding into a finely divided powder glass having a density greater than that of the serum phase of the blood; mixing the powder with a liquid having a density not greater than that of whole blood; allowing the mixture to stand so as to sediment the heavier particles and separating the latter from the remaining mixture; centrifuging the remaining mixture under a force greater in magnitude and duration than that used in the normal centrifugation of blood to precipitate particle therefrom; and removing and drying the precipitated particles.

Abstract: 905,339. Magnetic storage devices. GENERAL ELECTRIC CO. Ltd. Dec. 20, 1960 [Dec. 10, 1959], No. 42029/59. Class 38 (2). [Also in Groups XXIII and XXXIX] Thin magnetic films F each having an easy axis of magnetization, and of about 300 Angstom units thick, are deposited by low-pressure evaporation in the presence of a polarizing field on a vitreous enamelled surface of a polished metal sheet such as copper or aluminium. A number of separate storage areas, each comprising a separate film may be provided as shown, or alternatively discrete storage areas of a single film may be used. The magnetic films are covered with a film of polyethylene terephthalate on which is formed, by a photoetching process, rows of aluminium foil pick-up conductors. Above this are assembled, in turn, printed circuit boards respectively carrying row and column conductors. Similarprinted boards on the other side of the sheet may provide return current paths, or one set of conductors may have its return paths provided by the metal sheet itself. The presence of the metal sheet, whether used as a current path or not, is stated to have the advantage of reducing the inductances of the various conductors and so increasing the operating speed. The easy axes of the films may be slightly inclined with respect to the columns of the assembly as described in Specification 896,703 in which the manner of operation is also explained. Details of the composition of and the process in forming the vitreous enamel layer is described in the present Specification (see Group XXIII).

Abstract: 1373706 Force-transmitting devices; external shoe brakes SVENSKA AB BROMSREGULATOR 21 Sept 1972 43716/72 Headings F2E and F2F [Also in Division E2] A force transmitting device comprises the following coaxially arranged elements: a fixed or movable tube, a radially expandable casing axially movable within the tube when unexpanded and containing an enclosed deformable medium acted on by a force introducing rod and in turn acting on a force delivery means which is instituted by the movable tube or by a plunger or by an axially slidable housing, and an application means acting in the force introducing direction for causing displacement of the movable tube or the casing until a counter force acts to produce radial casing expansion, and frictional retention thereof in the fixed or movable tube. A fluid operated piston-cylinder unit 2, 1 has the rod 3 which extends into the casing 6, and the application means in the form of a spring 10<SP>11</SP> which lies between the piston 2 and the casing, or between an abutment 18 carried by the rod 3 and the casing, Fig. 4. The force delivery means may be a plunger or a hollow sleeve 11<SP>11</SP> which accepts a free end of the rod 3; in this example, since the rod extends through the easing 6 it has a step 12 to cause medium deformation upon a counter force acting through the sleeve into the medium 9. To reduce energy absorption due to the spring 10<SP>11</SP> a clutch comprises fingers 20 attached to the casing to lift fingers 17 carrying the spring abutment 18 from the rod 3 to remove the spring dependency therefrom. This clutch can alternatively be situated between the piston 2 and the casing 6. An alternative embodiment, Fig. 6, has the application spring 10 acting on an extension 5<SP>1</SP> of the tube 5, the casing 6 initially moved therewith by the rod 3 until a counter force on the extension 5<SP>1</SP> acts on the casing end 21 to cause medium deformation. The medium 9 is a polymer having a high bulk modulus. All examples provide a rapid take-up and then a high force transmission upon encountering a resistance. Figure 8 shows railway vehicle wheels 28 having opposed blocks 32 in frames 30, 31, the frame 30 being attached to the cylinder 1, and the other to the force delivery means via a rod 34. Other applications are for road vehicle brakes, hub pullers, clamping and tightening devices, and riveting punching and cutting machines.
