Abstract: 1,172,077. Treatment chambers. GOSUDARSTVENNY PROEKTNY INSTITUT "GIPROZDRAV". 3 Aug., 1967 [23 Nov., 1966], No. 52487/66. Heading A5R. Apparatus for use in the treatment of a limb, for example an arm or a leg, by increase or reduction of the ambient pressure, comprises an elongate pressure chamber having at one end an opening for receiving the limb to be treated and containing a support for the limb to be treated. Within the opening is mounted a flexible collar which is adapted to exert a localised and direct pressure on an adjacent portion of the limb when the limb is located in the chamber; the support carries a stop against which the limb may bear, is movable in a longitudinal direction with respect to the chamber and is adapted to be held in any one of a plurality of selected positions along the length of the chamber by means of a locking device which is located within the chamber. As illustrated in the drawing, a cylindrical chamber I of transparent material has at one end a flange 3, on which a heating element 17 may be mounted to be located within the chamber, and at the other end a flange 2 which defines an aperture for receiving a limb. Encircled by the aperture is a ring 4 carrying a hollow flexible collar 5 which may be inflated, e.g. by means of flexible bulb 6, thereby to exert on an adjacent portion of the limb a localised and direct pressure which may be regulated by means of a valve 7. Located within the chamber, to be movable longitudinally thereof along guides 10, is a support 8 which includes a stop 9 for holding in place the extremity of the limb. The support is connected to a spring-loaded dog 11 which is adapted to engage a toothed rack 12 attached to the wall of the chamber, the dog and rack forming a locking device whereby the support may be held in any one of a plurality of preset positions along the length of the chamber. The chamber is mounted on a carriage 13 at one end of which is a device 14 for raising or lowering the one end of the chamber as desired. The pressure in the chamber may be increased or reduced by means of an electrically driven pump 15, gauge 18 indicating the ambient pressure within the chamber. The patient may be secured in position by means of straps 16.

Abstract: 1407438 Semiconductor devices; image pickup tubes NORTH AMERICAN PHILIPS CORP 20 Nov 1972 [23 Nov 1971] 53507/72 Headings H1K and H1D A charge storage device such as the target of a vidicon camera tube is made by forming an array of alloyed PN junctions 8 in a semiconductor wafer 6, depositing an insulating coating 16, 17 over the excess metal 10 or any oxide film 12 thereon and between the junctions 8, e.g. in moats as shown, and immersing the device in liquid mercury which forms an amalgam with the excess metal 10. The amalgam is easily removed by shaking and lightly brushing and preferably by subsequently heating to above 180 C. in vacuum for 2 hours, and this results in removal of the unwanted insulating layers 12, 16, exposing clean semiconductor surfaces above the junctions 8 but leaving the intervening insulation 17 in place. For a Ge or Si wafer 6 the metal 10 may be In, Sn, Pb, Bi, Au, Tl, Ag, Zn or Ga, deposited through a mechanical mask an alloyed to the wafer 6 within windows in a silicon oxide layer which prevents spreading of the metal. This oxide layer is removed prior to etching of the moats, which may be effected electrolytically using the unalloyed metal 10 as a mask while illuminating the reverse side of the wafer 6. The insulating coating 16, 17 may be SiO 2 , formed from an oxygen-containing atmosphere into which SiO is evaporated.

Abstract: 1408394 Fluid-pressure servomotor systems BRYAN DONKIN CO Ltd 20 Nov 1972 [2 Dec 1971] 56052/71 Heading G3P In an apparatus for controlling the supply of pressure gas to a gas main 50, comprising a main governor valve 10 and a pilot valve 12, the two valves being so arranged that opening and closing of the main valve follows opening and closing of the pilot valve, the latter valve comprises two different area diaphragms 22, 24 which define control chambers 46 and 52, and chamber 46 is  connected, via line 48, to an upstream portion of  the main 50 whilst chamber 52 is connected, via  line 54, to a point on the outlet side of the governor 10. There is a differential pressure between the pressures in these lines which is dependent on the flow through the governor valve 10. The pilot valve is thus responsive to pressure at the upstream end of the main 50 and such response is modified in accordance with the demand for gas. Accordingly, an increase in pressure dictated by demand will substantially equal the pressure loss due to gas flow along the main. A needle valve 62, a volume regulator 60 and a load limiting regulator 56 are included in the connections between the two valves.

Abstract: 1,213,480. Fuel injection engines. MASCHINENFABRIK AUGSBURG - NURNBERG A.G. Dec.18, 1967 [Dec.16, 1966], No.57471/67. Heading F1B. In a diesel engine having a combustion chamber in the piston or cylinder head and combustion air circulation around the cylinder axis, the ratio of the quantity of fuel injected to provide a film on the combustion chamber wall to the quantity mixed directly with the air is varied continuously or intermittently. The ratio is varied in dependence upon the temperature of the combustion chamber wall or factors controlling or controlled by this temperature, e. g. engine load or the temperature of the exhaust pipe, valve stems, injection nozzles or part of the cylinder head adjacent the combustion chamber. The ratio may be adjusted by rotating the fuel injector or by varying the proportions of and/or the degree of atomization of fuel sprayed through two or more nozzle orifices assisted by varying the direction of rotation, speed and turbulence of the combustion air flow in the combustion chamber. The variations in air flow may be effected by screened inlet valves, butterfly valves with suitably shaped cut-outs immediately upstream of each inlet port or a butterfly valve in the inlet manifold. In the illustrated embodiment a temperature sensitive member 7 in the cylinder head emits pulses which operate a mechanical, hydraulic, pneumatic, electrical or thermal actuator controlling the injection nozzle 5 and an intake manifold butterfly 8. The injection nozzle 5 may be operated by a bi-metallic strip (9), Fig. 3 (not shown), around a part of the exhaust pipe 3. In a further embodiment, Fig. 4 (not shown), the injection nozzle 5 is operated by a lever mechanism (13) operated in dependence upon the output of the fuel injection pump (11) and an engine driven tachometer (15) and therefore the engine load.

Abstract: 1,221,771. Display device with moving reflectors. M. SUTIN. 15 June, 1970, No. 57749/66. Heading G5C. [Also in Divisions G2-G3] In apparatus for the production of moving coloured images on, e.g. a translucent screen 13, white light from a source 2 is focused by a lens system 18, and a rotatable carrier 7 carrying reflector surfaces 5 of different colours is so positioned relative to the source 2 that, what ever the carrier position, some of the surfaces 5 are substantially at the focus of the light and some at least of these surfaces reflect focused light on to the screen 13. The surfaces 5 may be coloured artificial gems. A crinkled sheet of silvered reflecting foil on a rotatable plate 16 reflects some light from the illuminated surfaces 5 on to the screen 13. The carrier 7 comprises a central conical portion and a peripheral portion divided into tags. In another embodiment (Fig. 1, not shown), the carrier (7) is the base of a truncated cone, the reflectors (5) being on the inclined surface thereof. The rotatable plate 16 is replaced by a number of small sheets (14) of silvered foil. A number of object shapes are cut in a circular rotatable disc (9) in the light path from the source (2) to the reflector (5). In a third embodiment (Figs. 4, 5, not shown), light from a low voltage lamp (26) partly surrounded by a reflector (27) falls on to facetted jewels (28) on the outside of a rotatable cylindrical carrier (25). Some of the light reflected by the jewels passes through a lens (29) on to a screen or wall, the lens being mounted in a slidable, specularly reflecting, turret (35) the axis of which is at right-angles to that of the light source. A reflector (30) reflects some of the light from the lamp (26) back on to the carrier (25) to increase the amount of light passing through the lens (29). A folded specular film (32) is provided inside the turret to enhance the moving effect of the light pattern on the screen or wall.
