Title: Improvements in or relating to fluid control systems
Inventor: FURLONG OWEN DESMOND
IPC: B64D13/04
Filed: 1965-04-02
Abstract: 1,106,251. Fluid-pressure servomotor system; pure fluid amplifiers. WESTLAND AIRCRAFT Ltd. Feb.14, 1966 [April 2, 1965], No.14078/65. Headings G3H and G3P. A fluid flow control system comprises a valve 70 controlling the flow in a duct 5 in response to the temperature in a duct 4. A valve 7 controls the pressure in a conduit 16 in response to the temperature, which pressure is a control signal to a pure fluid amplifier 17. The outlets 27, 28 of the amplifier, which are proportional to the signal inlet pressures 22, 23 form the inlets to a second amplifier 31, whose outlets 37, 38 are signal inlets for a third amplifier 41. The outlet 47 of this amplifier is proportional to the pressure in signal inlet 16 and is fed to a bellows 61 of a relay valve 60 to control the pressure acting on the diaphragm 67 of valve 70. A feedback pressure is fed from outlet 47 through line 51 to nozzles 55, 57, the flow to nozzle 55 being through a capacitor 53. As shown the valve 70 controls a ram duct 5 on an aircraft which acts as the coolant for a heat exchange 3. The control may be in response to flow. The system may be used to control the flow of radio-active waste from an atomic reactor.

Title: Improved method of producing a mixture of air and combustible vapour
IPC: F02M21/00
Filed: 1919-06-04
Abstract: 150,090. Harper, W. June 4, 1919 Density separators. -A process of preparing a mixture of air and combustible vapour from a heavy oil such as lubricating oil, is described as applied to an internal-combustion engine with rotating cylinders, on which a carburettor is connected to the hollow shaft, and an oil spray pump discharges lubricant into the mixture of air, vapour and spray from the carburettor. The combined mixture in the rotating crank chamber passes through holes 41 in a dished plate 40 in the piston and around a baffle 17 to the valve 13; the liquid elements are deposited on the baffling aurfaces, the lighter constituents being vaporized by the heated surfaces, and the residue which consists of lubricant passing through holes 44 to the cylinder walls.

IPC: B25B27/20
Filed: 1950-06-08
Abstract: 667,935. Holding-tools for inserting circlips. MORRIS MOTORS, Ltd. June 8, 1950, No. 14291/50. Class 61 (ii). [Also in Group XXII] A circlip is inserted into a bore in a member 29 by forcing it along a tapering passage 31 by a fluid pressure ram 5 so that it becomes contracted sufficiently to enter the bore. The tapering passage is formed within a cylindrical head 6 which is also formed with a lateral slot through which the ring or circlip 27 is inserted into the larger end of the passage and an extension 32 adapted to fit within the bore. The ram is magnetised to facilitate the correct insertion of the ring in the head and a bevel 33 at the end of the portion 32 facilitates the ejection of the ring into the bore, after which it may be pushed along until it springs into the groove 30. Circlips in each of two grooves 30, 35 may be used to retain a bearing in position within the member 29. The head 6 is at one end of a cylinder 1 in which piston 2 may be moved by compressed air from an inlet 23 against a spring 9 in order to push the ram 5 down the passage 32. Control of the ram is effected by a hollow handle 13 which may be slid along a piston valve 18 against a spring 22 so as to move an inlet port 16 into communication with a duct 20, 21. On a rearward movement of the handle, the cylinder 1 is exhausted through a port 17.

Patent GB-626405-A (GB)
Title: Improvements in or relating to the purification of penicillin salts
IPC: C07D499/16
Filed: 1947-05-30
Abstract: Penicillin salts are purified by alternate extractions from aqueous solutions into an aliphatic alcohol of 4 or 5 carbon atoms or a mixture of these compounds and from organic solvent solutions into water at a pH of 4.5-8.0, preferably in the range 6.0-8.0 The process may suitably be applied to the ammonium, substituted ammonium, sodium, potassium and rubidium salts of penicillin. The process may be used to effect partial separation of salts of the individual penicillins, e.g. on extraction from an aqueous phase to an organic solvent phase penicillin X remains in the aqueous phase and on re-extraction with water penicillin K remains in the organic solvent. The extraction may be performed by continuous counter-current methods.  When the solvent is butyl alcohol a ratio of butyl alcohol to aqueous phase of between 1 : 1 and 4 : 1 suitably between 2.0 : 1 and 1 : 1 is used for extraction from the aqueous phase and a ratio of water to butyl alcohol of less than 1 : 1, preferably between .03 : 1 and 1 : 1 is used for extraction from the butyl alcohol phase. In examples, solutions of sodium, ammonium, potassium and calcium penicillins are extracted successively with butyl alcohol and water giving in some cases partial separation of the various penicillins. The Provisional Specification describes also the use in the process of the present invention of organic solvents in general.

Abstract: 1310185 Shower-bath curtain supports G S BORSTCHER 12 May 1971 [14 May 1970 18 March 1971] 14384/71 Heading A4N A device for hanging a shower-bath curtain comprises a cylindrical disc 8, Fig.4 rotatably mounted on a spindle (7), Fig.3 (not shown) carried by a support 1, the spindle (7) and central bore 9 of the disc 8 both being frustoconical, the curtain 16 being suspended from the hook-shaped ends 14 of rods 11, the other ends (12) of the rods being rotatably mounted in recesses (10) spaced round at least part of the periphery of the disc 8. The rods may be fanned out so that the curtain 16 is semi-circular, Fig. 5 (not shown) or so that the curtain 16 defines a quadrant, Fig. 7 (not shown). The support 1 comprises a plate 2 and a right-angle bracket (6), one arm of which constitutes the spindle (7). Free rotation of the disc 8 on the spindle (7) is prevented by frictional forces therebetween. The peripheral recesses (10) are downwardly-tapering and the ends (12) of rods 11 are provided with similarly tapering bushings (13). Free rotation of the rods 11 in the recesses (10) is prevented by frictional forces between the bushings (13) and the disc 8. The ends (12) of the rods 11 are bent to form an angle within the range 120 to 130 degrees. In an alternative embodiment, Fig. 8, the bracket 6 is provided with a recess (20) Fig. 9, (not shown) which is substantially cylindrical with its axis parallel to that of the spindle 7. In the recess (20) is located the upper end of a column 21 on which a bar 25 carrying a shower head 27 is slidable. The rotation of the disc 8 on the spindle 7 is limited by a stop 28 projecting from the bracket 6 into a slot 29 provided in the disc 8. The disc 8 may be fastened on to the spindle 7, for example by a flange (30), Fig. 11 (not shown) in the central bore 9, which flange locates in a circumferential groove (31) on the spindle 7, or by a retaining ring (32), Fig.12, (not shown) which locates in a circumferential slot (33) provided in that part of the spindle 7 which projects above the disc 8.

Abstract: 872,863. Travelling wave tubes. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. April 28, 1960 [May 26, 1959], No. 14889/60. Drawings to Specification. Class 39(1). In an M type travelling wave tube an electron optical electrode system comprises a cathode and a mesh grid very close to the cathode there being one or more equipotential connections between the cathode and the mesh grid, so as to shield the region of the potential minimum of the space charge limited electron beam. This reduces noise in the apparatus, due to the fact that the potential minimum of the space charge limited electron beam is on the cathode side of the mesh grid. The grid-cathode connection may be inside or outside the tube. The cathode and grid may each be connected to the Wehnelt electrode. The grid is made of or plated with Au to reduce its secondary emissivity. The invention may be applied to M type backward wave oscillators or to M type travelling wave amplifiers using forward or backward waves. In backward wave oscillators, tuning is by varying the sole potential.
