Abstract: 1470975 Power steering CAM GEARS Ltd 9 July 1974 [18 July 1973] 34230/73 Heading B7H  In an hydraulic power-assisted steering system in which the two elements 51, 52 of a rotary valve are relatively rotatable subject to restraint by a torque rod, a source of fluid pressure 56 has one branch 57A supplying the assistance motor (not shown) via the valve and another branch 57B connecting the source to detent means which resist the relative rotation of the two valve elements. As shown, the detent means comprise steel balls 59 slidable in radial bores 58 in outer valve element 51 which in turn engage V-sectioned recesses 60 on the inner valve element 52. Increased drivers torque sensed by the torque rod results in relative rotation of the valve elements and hence increase in source pressure which is directed via line 57B and pressure chamber 57C to bores 58 to thrust the balls 58 inwardly into engagement with recesses 60 to lock the valve elements 51, 52.

Title: Equipment for microscopic absorption measurement
IPC: G02B21/00
Filed: 1955-12-05
Abstract: 800,656. Photo-electric absorption measuring apparatus. ZEISS-STIFTUNG, C., [trading as ZEISS, C., [Firm of]. Dec. 5, 1955 [Dec. 15, 1954], No. 34709/55. Class 40 (3). In microscope apparatus for measuring the absorption characteristics of a preparation 5<SP>1</SP>, a double diaphragm 8 is associated with the light source 1 so as to cause the preparation to be illuminated over two areas, one corresponding to the part whose absorption is to be measured, e.g. a cell nucleus, and the other to a reference part, e.g. the cell protoplasm or surrounding liquid. The transmitted light is projected on to a light-sensitive cell 7 by an objective 6 and the two diaphragm apertures occulted alternately by a sector shutter 9 so that an alternating current output is produced from the cell of amplitude proportional to the specific absorption. In accordance with the invention the apertures in the double diaphragm are made adjustable in size and in position relatively to each other for the purpose of selecting the two areas of the preparation. In an alternative construction, Fig. 2 (not shown), the double diaphragm 8 and shutter 9 are located in the plane of an intermediate image of the preparation formed by an objective between the preparation and light-sensitive cell. Reference is made to an arrangement in which the rotating shutter is dispensed with and the light from the test and reference parts of the preparation falls on separate cells. If the light source 1 comprises a monochromator, the double diaphragm is arranged symmetrically with respect to the exit slit in order that the apertures should pass light of the same wavelength.

Filed: 1947-12-30
Abstract: 658,257. Automatic regulation. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Dec. 30, 1947, No. 34739. Convention date, Oct. 29, 1945. [Class 38 (iv)] [Also in Group XL (a)] A high voltage source 29, e.g. the output circuit of a television line-scanning amplifier, supplies the anode of a cathode-ray tube, not shown, through a rectifier 28 and a lead 27. A voltage V<SP>11</SP> variable wih the anode voltage of the cathode-ray tube is obtained from a potentiometer 22 and applied in series with the constant volt-drop across a discharge tube 4 so as to apply to the grid-cathode circuit of a triode vave 6 a voltage, substantially proportional to the square-root of the cathode-ray tube anode voltage, controlling the energization of a focussing coil 7 of the cathode-ray tube from a separate H.T. source 1. After initially setting focus by means of an adjustable cathode resistor 8, preferably having a low temperature coefficient, the arrangement is such as to maintain focus with variations of cathode-ray tube anode voltage over a limited range. Discharge tube 4 is maintained conducting by being supplied from both sources 1 and 29, the constant voltage across it being available for other purposes if required. A simplified arrangement in which the voltage of the source energizing the focusing coil varies in proportion to the voltage applied to the anode of the cathode-ray tube is also described.

Title: Improvements relating to feeding apparatus for pigs or other livestock
IPC: A01K5/02
Filed: 1958-10-31
Abstract: 860,146. Feeding appliances for animals. BREEDON GARAGES Ltd., and SHIELDS, C. T. G. Oct. 28, 1959 [Oct. 31, 1958 ; Dec. 8. 1958], Nos. 34946/58 and 39422/58. Class 5(2). A feeding device for animals comprises a hopper 11 for dry meal fitted with a rotary agitator 40 and provided at its base with a plurality of openings through which the meal is discharged into a trough 22 under the control of a vaned, rotatable discharge mechanism 13. The discharge mechanism is rotated in response to the discharge of water from a cistern 31, means being provided for directing the water into the trough if desired, and for. controlling the quantity of meal and water discharged at one operation, and the time interval between successive operations. The shaft of the mechanism 13 is extended outside the hopper to carry a sprocket wheel 15 entrained by an endless chain 16 which is interrupted at two points to mount containers 20, the system being in equilibrium until water from the cistern 31 discharges via the syphon 34 and pipe 30 into one of the containers and thus causes movement of the chain. The syphon may be replaced by any device which causes water to discharge from the cistern when it has reached a certain level. Each container is provided with a hinged valve 21 attached to a chain 24 which is adjustably connected to the frame of the device, so that after the container has descended a predetermined distance, the valve opens and the water discharges into the container 28 and from thence via the pipe 29 to the trough 22. Adjustment of the chain 24, and hence the time interval between the moment at which the syphon operates and that at which the relevant valve 21 opens results in adjustment of the time during which the chain 16 moves, and therefore of the time for which the mechanism 13 rotates. The pipe 29 may be swivelled away from the trough if it is desired to feed dry meal. The cistern 31 is fed with water by an adjustable drip feed 35 from a reservoir 36 and contains a displacement tank 32, means being provided for controlling the amount of water in the tank 32, thereby controlling the amount of water discharged through the syphon at each operation of the device. The cock 30b is operated either manually or mechanically to divert alternative discharges from the cistern 31 to one or other of the containers 20. A movable plate may be mounted beneath the discharge orifices of the hopper 11 so that by moving the plate relative to the hopper the size of the apertures will be varied.

Title: A method of removing the reaction water from fuel cells
IPC: H01M8/08
Filed: 1962-09-17
Abstract: Water formed in a fuel cell is removed therefrom by feeding a controlled amount of the fuel cell electrolyte 3 (e.g. 6NKOH before dilution) to a solution of potassium carbonate 1 contained in a subsidiary cell and separated from the fuel cell unit by a cation exchange membrane 17 through which K ions pass to the fuel cell electrolyte thus regenerating it. The cathode of the fuel cell electrodes 11 may serve also as cathode for the electrodialysis chamber containing an anode 6.  The diluted carbonate solution overflows into a pipe 5 into the dialysis chamber 1, and is circulated by a pump 8 or gas lift and is sprayed over a mass of inert material 7 in open air to promote evaporation at normal temperatures.  The reconcentrated solution then returns to the fuel cell.  The OH ions in the overflowing solution neutralizes the CO2 produced by electrolysis in the dialysis chamber.  The gas lift may be provided by the fuel gas, or oxygen used in <PICT:0988103/C6-C7/1> the fuel cell, and is dried and freed from CO2 before admission to the fuel cell.  The process may be made automatic in a modification (not shown) by mounting an overflow chamber above the fuel cell, and when full the liquid level closes electrical contacts which opens a valve at the base allowing the liquid to enter the dialysis chamber. The electrical elements may be operated by fuel cell current.
