Title: Improvements in or relating to an apparatus for adjusting a fluid flow
IPC: G05D7/01
Filed: 1969-10-07
Abstract: 1,237,485. Valves. LUCIFER S.A. 7 Oct., 1969. [31 Oct., 1968], No. 49229/69. Heading F2V. A fluid flow is regulated by a first closure member 6 slidable axially between a closed and an open position, and a second closure member 16 adapted to be shifted axially with respect to a port 9 by a control member 11. The member 6 is of plastics material and is held against a seat 7 by a weak spring 20 until it is lifted by fluid pressure at the inlet 3. Reverse flow from a port 4 is regulated by adjusting the member 16. At the position corresponding to maximum flow through the port 9, shoulders 18, 19 engage to cause the member 6 to be moved away from its seat and provide a more rapid increase in the rate of flow for each increment of adjustment.

Abstract: 1,060,640. Subtracters. STANDARD TELEPHONES & CABLES Ltd. Dec. 13, 1963 [Dec. 17, 1962], No. 49440/63. Heading G4A. [Also in Division H3] An anti-coincidence logic circuit (see Division H3) comprises a plurality of input terminals each coupled via a resistor to a separate terminal of a reactance and a source of clock pulses coupled via one or more diodes to each reactance. As shown, input terminals a x , a n-x  are each coupled via a resistor to a capacitor. Negative clock pulses are coupled to each point via diodes D x , D n-x . If the potential at both of the logic input terminals is zero or negative, the capacitor will not be charged and no output will be obtained. If, however, the negative potential is not fed to both logic input terminals (anti-coincidence) the capacitor will charge negatively during the clock pulses and discharge following the trailing edge of the clock pulse, feeding a positive output via one of the diodes. In Fig. 3 (not shown) three data input terminals are respectively connected via an individual resistor to each of three star-connected capacitors. Half-subtractor circuits:-The circuit may be used as a half-subtractor if the minuend and the subtrahend are respectively fed to the logic inputs. A borrow output is available at A or B.

Abstract: 1370308 Discharging grain &c from endless conveyers; shoots JOHN RUTHERFORD & SONS (MFG) Ltd 25 Oct 1972 [26 Oct 1971] 49736/71 Headings B8A and B8S An aperture in the base of an overhead conveyer trough 2, may be uncovered for discharge of material from the conveyer, by the action of a shutter plate 12, when the latter is moved from the full line to the dot-dash line position. The material is then discharged by a shoot 10. The plate 12 may however be pivoted about its left hand end, in which case the material passes to a shoot 10<SP>1</SP>. The plate 12 is operated by displacing an arm 34. Either end of the arm 34 is downwardly pulled by means of a rope (not shown) according to whether discharge from the shoot 10, or shoot 10<SP>1</SP>, is desired. This rotates a shaft 30 journalled in the frame. The shaft 30 carries arms 28 which are rigidly connected at their upper ends to a rod 26. Each end of the latter engages a slot 36 in a respective side plate 22 of a carriage 18. The latter has rollers 24 which are mounted in channel shaped tracks formed on either side of the shutter plate 12.

Abstract: 1,021,177. Delivering measured quantities of liquid. VYZKUMNY USTAV ENERGETICKY. Dec. 18, 1963 [March 19, 1963], No. 49904/63. Heading B8N. Apparatus for automatically maintaining the liquid level in a dosing apparatus in which the discharge is started by a pressure pulse comprises a supply tube 2 connected to a dosing vessel 1 and leading therefrom into a storage tank 3, the tube terminating in an open end 24 located at the desired control liquid level 31 and being provided with an orifice 23 above the bottom of the tank. The dosing vessel 1 is connected via a tube 6 to a pipe 4 into which a measured amount of a different liquid is poured, the liquid flowing via a restriction 41, into a container 5; a tube 13 also leads from the vessel into the container. In operation, the tank is filled with a liquid up to a maximum level 32, the liquid then flowing via the orifice 23, into the dosing vessel as shown. When the different liquid is poured into the tube 4, due to the restriction 41, it rises into the tube 6 thereby causing a pressure which acts on the liquid in the vessel 1. The liquid in the tube 13 then rises to the level 31, and remains at this level since the liquid above the junction of the tube 2 with the vessel is being forced through this tube and overflowing at the level 31 into the tank. When the liquid level in the vessel drops below the above junction point, the liquid in the vessel is then forced over a bend 12 in the tube 13 where it flows into the container S.

Abstract: 1281363 Semi-conductor devices PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 13 Oct 1969 [16 Oct 1968] 50104/69 Heading H1K In a JUGFET having a strip like upper gate region extending parallel to strip like source and drain electrodes so that its ends contact the substrate which forms a lower gate region, the upper gate is also connected to the substrate at one or more points between its ends. The extra connection may be a columner region extending perpendicular to the major faces of the wafer through the channel region, or a shallow surface region extending at right angles to the gate region. The extra connection reduces the series resistance of the upper gate region. Fig. 2 shows a cross-section through the length of a strip shaped upper gate region 13 contacting the substrate 4 at its ends 14 and 15 and also at intermediate points by means of regions 17. A plurality of such gate regions are arranged between alternate source and drain contacts to form a high power device, the separate source contacts and drain contacts being interconnected to form interdigitated electrodes, Fig. 1 (not shown). The device is produced by epitaxially depositing an N-type layer (6) of Si doped with As on to a P-type substrate 4, thermally oxidizing, photomasking and etching to form windows through which B is diffused to form P-type edge region 4A and columnar regions 17, reinforcing the oxide formed during the diffusion by a thermal oxidation if necessary, etching elongate windows and diffusing-in B to form bridges 13 contacting the columns 17. Contact windows are etched and P is diffused-in to form N<SP>+</SP>-type source and drain contact regions on either side of the gate regions, the windows are cleared of oxide by means of a light etch and Al is vapour deposited masked and etched. The underside of the wafer is ground down and soldered to a plate to form an ohmic gate contact to the substrate and the transistor is mounted in an envelope. A plurality of transistors or a plurality of ICs containing such a transistor may be simultaneously produced in a wafer which is then subdivided by sawing or by breaking. Instead of epitaxial deposition the N-type region may be diffused-in to form the channel regions surrounding the columnar connecting regions. The gate connection may also be applied to the upper face of the wafer. In a second embodiment, Fig. 8 (not shown), the upper gate regions are connected to the substrate by similarly proportioned regions extending at right angles so that a grid-shaped structure is formed. Parallel source and drain contacts are formed in the openings of the grid as appropriate and are contacted by electrode strips insulated from the gate interconnecting regions by an insulating layer.

Title: Process for the purification of solvents
Inventor: AUCHAPT PIERRE
IPC: B01D3/38
Filed: 1964-12-14
Abstract: Contaminated solvents which have been employed in nuclear industrial processes are purified by steam distillation, first adding a quantity of uranium salt to the solvent or mixture of solvents so that the resulting mixture has less than 20 g/l of uranium, and then contacting this solvent mixture with steam until it has been reduced to 2% of its original volume.  The process may be carried out at atmospheric pressure or under reduced pressure, e.g. 50-400 mm. Hg. The solvent may be reduced by steam distillation to a volume corresponding to 10 to 15% of its original volume before the uranium salt is added and further steam distillation takes place.  The uranium salt may be uranyl nitrate.  An example given is concerned with a mixture of solvents consisting of 30% by weight tributyl phosphate and 70% by weight dodecane.
