Title: Oil and water fluid compositions and methods of stabilizing same
IPC: C10N10/16
Filed: 1977-08-15
Abstract: The composition contains a dispersion of oil and water, an emulsifying agent (anionic and/or nonionic) imparting electronegativity to the oily phase of the dispersion and, as stabiliser, a multivalent metal ion bonded to the electronegative oily phase and introduced in the form of a complex of a metal ion and of a polyfunctional organic ligand (for example disodium monocopper(II) citrate). This complex can, between pH 7 and 9, release metal cations to stabilise the emulsion and to prevent its degradation. The service life of cutting fluids for metal machining can thus be very considerably prolonged.

Title: Improvements in or relating to electron multipliers
IPC: H01J43/06
Filed: 1955-11-30
Abstract: 807,997. Electron multipliers. TWENTIETH CENTURY ELECTRONICS Ltd., JENNINGS, A. E., and MISSO, C. E. F. Nov. 2, 1956 [Nov. 30, 1955], No. 34242/55. Class 39(1). The dynodes P, Fig. 3, of an electron multiplier are of the venetian blind type, the inclined slats 2 being so disposed that each dynode is not opaque when viewed orthogonally, but two consecutive dynodes together are opaque. Electrons can thus pass directly through not more than one dynode. The depth d of each slat is approximately equal to the distance between them, and the slats are inclined at 37¢ degrees to the dynode plane. In Fig. 4 (not shown) actual dimensions are given. In the arrangement of Fig. 5, only a part of each slat is inclined out of the dynode plane. This enables the required conditions of opacity to be obtained with an angle of inclination greater than 37¢ degrees so increasing the extraction efficiency.

Title: Improvements in or relating to the control of aircraft cabin super-chargers
IPC: B64D13/04
Filed: 1946-11-19
Abstract: 619,016. Fluid-pressure servomotor-control systems; relief valves. BENDIX AVIATION CORPORATION. Nov. 19, 1946, No. 34303. Convention date, Dec. 21, 1945. [Class 135] A system for controlling the amount of air delivered by a supercharger to an aircraft cabin comprises a variable speed device between the supercharger and its driving engine, a differential bellows responsive to the pressures at the inlet and outlet of the supercharger, with a constriction in the line between the supercharger outlet and the bellows, and controlling means between the bellows and the variable speed device to increase the speed ratio as the pressure differential across the bellows decreases. As shown, the engine shaft 22 drives a ring gear 20 in a sun-and-planet differential gear of which the sun wheel 14 drives the supercharger. The planetary gears 18 are carried by a spider driving a gear pump 28, the output of which can be throttled by a valve 47, whereby the torque driving the supercharger will be proportional to the back pressure at the pump. The input pressure of the supercharger is applied to the inside of a bellows 35 and the output pressure is applied through a constriction 35C to the outside of the bellows, and this differential pressure can be varied by adjustment of the loading on a valve 35D situated in a byepass from the outlet to the inlet. Bellows 35 actuates a piston valve 39 and, when this valve is in neutral position, the force due to the bellows and its adjustable loading spring 36 is balanced by the output pressure of pump 28 acting through conduits 50, 51. When valve 39 moves, the output pressure of pump 28 is applied through a conduit 45 to either end of a double piston 48, 49 formed on valve 47, and the latter will be moved to vary the back pressure of the pump and, hence, the speed of the supercharger. The output pressure of the pump is also applied through a conduit 40B to act as a fluid loading to a surge prevention valve 53 controlling a vent to atmosphere from the supercharger outlet pipe. When flow from the supercharger becomes too low, the pressure differential will increase and valve 39 will be moved so far to the right that land 40 will place conduit 40B in connection with exhaust port 46. The loading pressure in the space comprised between a fixed piston 58 and a floating cylinder 56 will thus be lowered sufficiently to allow valve 53 to open and increase the flow from the supercharger sufficiently to prevent surging.

Abstract: 902,034. Knitting-machines. COTTON Ltd., WILLIAM. Oct. 24, 1958 [Nov. 5, 1957], No. 34404/57. Class 74 (2). A straight-bar rib machine has yarn-engaging members 9 associated with the machine needles and on to which the sinker loops 16 drop in front of an abutment 13 on each member after the frame needles 6 have drawn their loops, Fig. 3. The members 9 are then advanced along the needles to ensure that the newlylaid yarn is engaged beneath the beards of the machine needles and is separated from the previous course loops 15 on these needles, Fig. 4. Thereafter the machine needle beards are pressed and these needles and the members 9 are withdrawn to draw loops of the newly laid yarn and to cast off the loops of the previous course, Fig. 6. Prior to the advancement of the machine needles for the next course, the members 9 are advanced to a position above the cast off loops so as to ensure that these loops ride under the needle shanks when the machine needles are advanced, Fig. 7. The members 9 are mounted in a bar operated from the main cam-shaft which may be shogged for quality control. The members 9 may be cranked to operate from above, below or at the side of the needles. They may also be shogged to spread the loops.

Abstract: 301,391. British Thomson-Houston Co., Ltd., (Assignees of Taylor, J. B.). Nov. 28, 1927, [Convention date]. Photographic recorders. -In apparatus for making a photographic record of vibrations and reproducing therefrom, a beam of light is directed through an optical system including a cylindrical lens with axis parallel to the direction of movement of the light sensitive record-receiving member, which system forms it into a narrow strip, and renders a light slit in a screen unnecessary. The arrangement provides for making a record of varying intensity or of varying width, and means are provided for monitoring and for viewing the image to facilitate adjustment. In recording, a beam from a source 12, Fig. 2, is directed through a lens 15 past a diaphragm 16 with one side cut away to give the beam a straight edge, and the beam is reflected by an adjustable mirror 17 on to a mirror 11 influenced by the vibrations, for example an oscillograph galvanometer influenced by a condenser microphone subjected to sounds to be recorded. The mirror 11 reflects the beam through one side of an aperture in plate 19 so that the sharp edge of the beam is about the middle of the aperture. Beyond this the beam passes through a cylindrical lens 21, whose axis is parallel to the direction of movement of the film 2, and then through an inclined glass plate 28 and condensing lenses 23, 24 which form a thin strip image 25 or the sensitized film, the end of the thin image tracing a wavy line on the film in accordance with the vibration of the beam. A small part of the beam is reflected by the plate 28 on to a photo-electric cell 35 connected in a circuit for monitoring the recording, and a small part of the light is reflected from the strip 2 back to the plate 28 which deflects it through a lens 30 on to a ground glass screen 31 for observing the position of the image on the film, a scale being marked on the screen if desired. The optical system apart from the lens 18 and mirror 11 may be mounted in a tube provided with adjustment means, the image in the screen 31 serving to facilitate the adjustment. Records with images of varying intensity can be made by rotating the mirror 11 through 90‹ in which case a varying amount of light passes through the aperture in the plate 19 on to the film 2. The optical system described may be used in reproducing in which case a steady beam of light is directed through the film on to a photo-electric cell.

Title: Improvements in or relating to Vibration Dampers
IPC: F16F15/023
Filed: 1967-07-28
Abstract: 1,176,975. Fluid dampers. HOUDAILLE INDUSTRIES Inc. 28 July, 1967 [8 Aug., 1966], No. 34840/67. Heading F2S. [Also in Division G1] Radial vibrations of a rotating shaft 10 are damped by fitting to it, outside the shaft bearing 9 and inside a fixed support structure (not shown, but bolted to the fixing lug 11), a damper consisting of a liquid-filled chamber 17 in which the liquid extends between closely spaced radially extending members 18 and 19, the film of liquid between these members undergoing viscous shear when the shaft is radially displaced. The chamber 17 is radially bounded by concentric rigid members 7 and 8 and axially bounded by flexible members 15; and member 7 carries a blade constituting the radial member 18 whilst member 8 carries a pair of such blades or a single bifurcated element constituting the radial member 19. Thus, under radial vibration, members 7 and 8 can move relative to each other but the fluid between the blades damps such movement. To compensate for the temperature dependence of the fluid's viscosity the blades 19 may (Fig. 3, not shown) be formed of bimetallic strip, so that the gap between blades 18 and 19 varies in width with temperature. Alternatively the blades 18 and 19 may all have toothed peripheries and blades 19 made to rotate relative to blade 18 about the axis of shaft 10 whenever the temperature changes, thus changing the area of overlap between the blades. Fig. 2 (not shown, but see Division G1) depicts means to control such relative rotation in dependence on temperatures; a liquid-filled chamber pushes out a piston when the liquid expands and the piston is returned by a spring when the liquid contracts, movement of the piston effecting relative rotation of blades 18 and 19.
