Patent GB-134228-A (GB)
Abstract: 134,228. De Haen Chemische Fabrik List Ges. Dec. 4, 1917, [Convention date]. Cellulose solutions, making films from, processes for.-Porous membranes are prepared by evaporating the solvent from a film of a solution of a cellulose ester, other than viscose, in a purality of solvents individually capable of dissolving the ester and volatile at ordinary temperature, the evaporation being conducted in a moist atmosphere the temperature and humidity of which is maintained substantially constant; water may be added to the original cellulose ester solution. The membrane so produced is opaque iu appearance and of high filtering capacity; and the permeability of the membrane can be adjusted within wide limits by varying the percentage of cellulose ester in the solution, the composition of the solvent mixture, or more conveniently, the amount of moisture in the atmosphere, or the quantity of water added to the solution, the permeability of the membrane being greater as the humidity is increased. In an example, celloidine is dissolved in a mixture of glacial acetic acid and acetone; the solution is then spread as a film upon a glass plate and afterwards the solvent is evaporated in an atmosphere of about 60 per cent humidity and at about 18‹ C. Other preferred solvent mixtures consist on the one hand of chloroform or acetic ether, and on the other hand of alcohols, ethers, and other solvents for cellulose esters; and combination of these mixtures may be used. The films so obtained are usually corrugated, but can be prepared in a permanently smooth condition by stretching and at the same time heating them by hot water or steam. The membranes may be supported on a porous or perforated plate, drum, or vessel.

Abstract: 863,874. Ultrasonic inspection devices. KELVIN & HUGHES Ltd. April 24, 1959 [April 28, 1958], No. 13439/58. Class 40(7) [Also in Group V1] Relates to the ultrasonic examination of the interior of a body by a transmit/receive transducer means moved in a plane over the body's surface and scanning angularly about an axis. According to the invention an indicator is deflected over a straight line from an origin positionally controlled by the axis movement, the straight line direction is caused to follow the angular scan and the indicator is modulated or rendered operative and inoperative in dependence on received echo signals. In the embodiment the human body is explored and the indicator is an intensity-modulated cathode-ray tube (C.R.T.) beam. Probe 27 containing piezoelectric transmitting and receiving crystals is mounted for limited rocking about axis 28 the rocking being followed electrically by sine/cosine potentiometer 31. Probe support 23 is guided by rollers 24 for vertical movement and carriage 25 is horizontally movable on rails 26, these movements being followed electrically by potentiometers 40, 37. The transmitted pulse is delayed with respect to the initiation of the vertical and horizontal deflection sawtooth waveforms and a second delay circuit renders the C.R.T. operative before a pulse is transmitted, the Fig. (Prov., not shown). The second delay circuit may be adjustable and calibrated for ranging. The display produced shows the surface of, e.g. a cyst 44<SP>1</SP>, the successive arcs 43<SP>1</SP>a ... d over which the probe face rocks and the transmitted pulses a<SP>1</SP> ... d<SP>1</SP>; non-planar interior surfaces are thus well defined. The display may be photographed to enable the whole presentation to be viewed at one time or the screen phosphor stores a latent image until made visible by infra-red irradiation. Rails 26 are movable in a perpendicular direction for portrayal of parallel cross-sections. The indicator may be a pen recorder and the probe may be fixed but with an oscillating beam.

Abstract: 572,967. Gear wheel pumps or motors. PUMP ENGINEERING SERVICE CORPORATION. Aug. 19, 1943, No. 13530. Convention date, April 15, 1942. [Class 110 (ii)] In a gear pump or motor end sealing plates 38 on the bearing bushes are subjected to the high-pressure fluid on the outside and a relieving pressure in each space 46, on the inside. These pressures may act on one end of each gear only. Duplicated, valve-controlled ports, allow the relevant pressures to function, when the driving shaft 74 (for a pump) is reversed. Bearing bushes 32 have flat portions, 38a, Fig. 5, and sealing plugs 38c. The housing 11 and end closure plates 17 are of lightweight material, such as aluminium and the bushes of bronze. Sealing rings 39 are provided. The bushes, and plates 38, have limited axial play between high and low pressure areas. Fig. 8 shows fluid from the pressure conduit 49, of the pump, forcing down valve 52 and entering a space 41, but if the pump drive is reversed, valve 52 closes, and valve 52a opens. The space 46 communicates with the low pressure conduit 48 by way of either valve 57 or 57a. A passage 61 connects the two low pressure regions. Springs 63 press on washers 62 to give initial pressure between the gear faces and the bush flanges. Passages 66, 71, through the gears allow low-pressure fluid to pass to the inner face of a flexible coupling 68. Splines 73 are forced on an extension 72 of the gear journal 34 to engage with splines on a shaft 74 which has a flange 75 engaging a bearing ring 76. The latter presses against a flexible ring 77. A compression spring 80 is provided. The recess 46 may be cut in the gear instead of in the bush, and may vary in shape.
