Title: Method and apparatus for treating blood
Inventor: MARTIN RICHARD CARVER
IPC: A61M1/02
Filed: 1966-06-21
Abstract: 1,131,117. Multi-compartment bags. ELLIOT LABORATORIES Inc. 21 June, 1966, No. 27783/66. Heading B8K. [Also in Divisions A5, B1 and F1] Red blood cells are washed in bag 2, to remove an aqueous dimethyl sulphoxide-glucose-fructose solution added thereto to protect cells during freezing and thawing, by adding wash water, containing dextrose and fructose, by tube 76, mixing cells and water by rotating P.T.F.E. coated magnetic rod 94 by means of a rotating field from coil 96 (Fig. 2, not shown), allowing cells and water to separate by settling, and deforming the bag wall to lift the water out of or into another part of the bag, and the process is repeated with further wash water. Blood is initially collected from the donor and centrifuged in a separate bag 118, plasma is withdrawn and red cells transferred to bag 2 by tubes 56, 60. Tube 60 ends in a cannula 62, normally caused by protective cap 104, which is either pushed through a pierceable diaphragm or forces out a sphere or bung resiliently gripped in and blocking outlet 124 (Figs. 6, 7, 18). (Similar connections are used to blood-receiving bag 82). The additive is delivered from bottle 130, making similar connection with line 64, and tube 56 is tied and cut. Bag 2 is used to store the blood in refrigerator. When required blood is thawed and tube 76, shown rolled tight, is opened and its cannula 78 connected to wash water bottle (132) (Fig. 11, not shown). Bag 2 is divided by a membrane (10) into an air chamber, to which squeeze bulb 22 may be connected and a chamber receiving the liquids, and with bag 2 hooked on to inclined plate 98, successive doses of wash water are supplied, tube 76 being clamped and the air chamber inflated after each settling step (Fig. 12, not shown) to squeeze the water layer out of upper part 28 into a connected bag 38 (shown rolled up). Membrane (10) and wall (6) of the bags are ribbed to facilitate flow past compressed part of bag. Once flow has begun siphon action maintains it until air pressure is released. After washing, tubes 34, 76 are tied and cut and plasma is delivered into the bag by tube 72 with its cannula. After mixing, the reconstituted blood is transferred to integral bag 82, after manipulating a sphere 86 out of the connecting tube, tube 80 is cut and tied and blood ready for use. In an alternative embodiment (Figs. 19-21, not shown) the blood bag (200) has a wide end (202) to receive used wash water, and membrane (10) is omitted, the wash water being lifted from the red cells by moving an upper support, over which the bag is hung, downwards along the sloping bag portion. Bags are made of polyvinyl chloride acetate, polyethylene or polytrichlorfluoroethylene. The inflatable membrane of the first embodiment may be replaced by a second bag within bag 2.

Abstract: 363,000. Colour photography. COLOUR PHOTOGRAPHS (BRITISH & FOREIGN), Ltd., BECKER, W. T, L., OLIVER, L. W., Victoria Road, Willesden, MURRAY, H. D. and SPENCER, D. A., 118, Fulham Road, both in London. Sept. 17, 1930, No. 27803. [Classes 97 (i), 98 (i), and 98 (ii).] Photographs in natural colours are produced by exposing successive or adjacent areas of a composite two layer film, the different coloured images recorded by the areas being then combined. The exposures of the areas may be successive or a light splitting device may be used to produce the two images simultaneously. In one example a kinematograph film consists of a front layer of blue sensitive emulsion and a rear layer of panchromatic emulsion separated by a colour filter having alternate areas coloured red and green. Alternatively, the colour filter may be a continuous yellow filter and a shutter having alternating magenta and green sectors located in front of the lens. In a further example, a light dividing means is used and two beams coloured magenta and yellow respectively by means of light filters fall on a film having a green sensitive front emulsion and a panchromatic rear emulsion separated by a continuous red filter. The Provisional Specification describes also apparatus for exposing the sensitive material comprising a sliding back for adapting to a camera with means for actuating the shutter for each exposure. The slide may be mounted between rollers and bear a cross-head co-operating with an actuating arm driven by clockwork, which effects the movement of the slide at the end of a half revolution of the arm. The clockwork opens and closes the shutter during each half revolution, the movement being controlled by pneumatic means. Means for rendering the claw feed of kinematograph cameras inoperative for the necessary period for the exposure of the double film are also described.

Title: Improvements in or relating to the transmission of power
IPC: B60K17/10
Filed: 1920-10-05
Abstract: 173,338. Ricardo, H. R. Oct. 5, 1920. Transmitting power.-Apparatus for the transmission of power, for example to the wheels of a motor road vehicle, comprises one or more units each consisting of an air-compressor cylinder between two internal-combustion engine cylinders and a steam boiler heated by the engine exhaust products and delivering steam to the compressed and heated air as it passes to the air motors; the engine fuel supply, air inlet, and water supply are controlled by the air pressure. Fig. 1 shows the general arrangement of apparatus applied to the driving of the wheels of a motor-vehicle. A combined engine and compressor A delivers air through a pipe J to a casing J<2>, from which it flows by pipes J<3> to air motors C; a portion of the air also passes to a reservoir X in shunt with the remainder of the system. The exhaust gases from the internalcombustion engine pass through a pipe within the pipe J, and through the casing J<2>, and are finally used to generate steam in a coil 0 within a casing H<3> which also acts as a silencer; the steam is added to the air in the motors C. The compressor comprises a cylinder disposed between a pair of engine cylinders, the three pistons being connected to a common crank-shaft so that a balance is attained, the weight of the compressor piston being twice that of either engine piston, and the cranks being disposed oppositely. A pair of piston or tubular air inlet valves is provided, one with fixed timing and the other K', Fig. 3, adjustable; they reciprocate oppositely, balancing each other. The valve K<1> is formed as a notched annulus which can be rotated by a forked rod K<7> so as to present varying widths passing across ports L<2> in the valve cylinder L communicating with ports in the compressor cylinder, as the valve is reciprocated by an eccentric K<6>. The rod K<7> is turned by a handle K<9> actuated automatically by the air pressure. A rising torque-characteristic is obtained by the late closing of the engine and compressor inlet valves. The water supply for the steam-generating coil is derived from the water jacket of the combined engine and compressor by a pump actuated by an eccentric on the engine shaft, and a by-pass controlled by a valve is provided in connection with the water system. The combustion engine inlet and outlet are controlled by poppet valves actuated by cams carried on a countershaft driven from the engine shaft and capable of sliding so as to vary the form of the cam face presented to the valve stems, so that the cut-off can be varied and reversal effected. A foot-actuated throttle valve is disposed in the air-inlet passage of the air motors. The compressor inlet valve L<1>, Fig. 9, water bypass valve W, and a throttle valve for the engine are actuated automatically by the pressure of air in the compressor delivery pipe acting on a spring-pressed piston within a cylinder V<1>, through linkwork K<10>, K<11>, W<1>, W<3>, and U<2> respectively.
