Title: Improvements relating to body-stabilising arrangements of motor vehicles
Inventor: WINSEN FRIEDRICH VAN
IPC: B60G21/055
Filed: 1964-09-01
Abstract: 1,012,087. Preventing lateral canting. DAIMLER-BENZ A.G. Sept. 1, 1964, No. 35793/64. Addition to 895,095. Heading B7D. In a vehicle suspension according to Specification 895,095 in which the suspensions of wheels of a pair on opposite sides of the vehicle are interconnected by a torsion-bar divided in its mid length and its ends being connected by a servomotor which can be operated so that the parts of the rod can be rotated relatively to one another, the servomotors 4 and 50 connecting the torsion-rod parts 5, 6 and 7, 8 are supplied in parallel with fluid from a control valve 67 incorporated in the servomotor 4, the fluid pressure being generated by a pump 61 having supply and return lines 22, 23. The control valve is itself controlled in response to centrifugal forces acting upon the vehicle and causing the generation of pressure in one or other of lines 26 and 27 leading to a cylinder in which works a piston 58 normally centred by a pair of springs 59, 60 and connected to the spool 55 of the valve 67. The casing of valve 67 is connected to the piston 13 of the servomotor 4, the arrangement being such that as the valve 67 is operated, e.g. when the vehicle is rounding a bend, the pistons 13 and 62 are moved to relatively rotate the torsion-bar parts in a direction to restore the vehicle to an upright position. The valve 67 moves with piston 13 to a position in which the fluid passing through the valve is throttled. The extent of correction of the front and rear wheel pairs, respectively, may be varied by having servomotor pistons of different sizes or by having crank arms of different lengths on the torsion rods.

Title: Device for Triggering a Spark Gap at High Rate
IPC: H01J17/00
Filed: 1967-08-04
Abstract: 1,191,737. Spark gaps; lasers. COMPAGNIE GENERAL D'ELECTRICITE. 4 Aug., 1967 [8 Aug., 19661, No. 35886/67. Headings H1C, H1D and H1X. [Also in Division G3] A spark gap 16 is repeatedly triggered by the beam 12 of a continuously operating gas laser 11 passing through at least one aperture 15 in a rotating opaque disc 14. The disc 14 is rotated by an electric motor 13. The apertures 15 may be circular holes or arcuate slots and may contain or be associated with lenses. A plurality of spark gaps of the same size arranged along the beam path may be triggered practically simultaneously or spark gaps of different sizes may be triggered selectively by using apertures of different sizes or lenses of different focal lengths. Apertures of variable size may be provided by two discs relatively movable through a limited angle. (Figs. 5a and 5b, not shown); such movement may be servocontrolled. The speed of the motor 13 may be servo-controlled (see Division G3) at the highest possible triggering rate. The spark gap may have a gas filling of mercury vapour, hydrogen, air, nitrogen, sulphur-hexafluoride, argon or helium, thus enabling different deionization times to be obtained.

Title: An improved process and apparatus for separating solid substances and liquids by decomposition, more particularly for recovering substances from the waste water of paper factories and the like
IPC: D21F1/66
Filed: 1937-12-28
Abstract: 513,308. Gravity-separation apparatus. HAHNLE, C. KURTZ-, and KURTZ, H., (trading as WANGNER, H. [Firm of]). Dec. 28, 1937,. No. 35945. Void. Convention date, Dec. 28, 1936. [Class 111] A process for recovering substances from waste liquids is characterized in that the mixture. to be separated flows into vessels successiv'ely and is then allowed to remain quiescent. until the solids have separated out, the liquids and solids being then withdrawn independently. In the arrangement shown six settling vessels four of which are shown, are connected to a rotary valve a which is also connected at b to a supply vessel 7, and at c to a discharge outlet. The valve a always connects two adjacent settling vessels to supply and discharge respectively, while the remaining vessels are shut off. In the discharge conduit is a window adapted to co-operate with an electric light control cell d the light being determined by the transparency of the substance flowing through the discharge conduit. In this conduit is a further rotary valve e for directing the discharged substance either to an outlet f or an outlet g. Assuming that vessel 1 is connected to the supply vessel 7 and vessel 2 is connected to the discharge conduit c, the substance deposited at the bottom of vessel 2 flows through conduit c and valve e to outlet f. When clear water commences to flow the cell d switches on an electric motor which turns the valve e to connect discharge to g, the motor then stopping. At the same time waste water flows from vessel 7 to vessel 1 until botn vessels are full, whereupon a float 8 operates the electric motor by means of a relay switch. The motor changes the position of the valve a connecting it operatively with vessels 2 and 3. The valve e is also brought back to its initial position.

Patent GB-793655-A (GB)
Title: Improvements in steel manufacture
IPC: F27B3/22
Filed: 1955-12-16
Abstract: In the refining of steel in open hearth furnaces by directing a stream of oxygen on to the molten charge, as disclosed for instance in Specification 758,529, the nozzle of the water-cooled oxygen gun used to inject the oxygen on to the bath is directed at an angle to the vertical and is disposed parallel to the vertical plane through the longitudinal axis of the furnace.  By this means the pressure of the oxygen and therefore the delivery rate may be considerably increased without damage to the furnace structure by splashing.  With the nozzle bent at 25 degrees to the vertical and disposed 5 inches above the bath, slag thrown up from the bath clears the nozzle.  With a 225 ton furnace, and starting with a carbon content of 0.35 per cent, use of the above technique enables an average decarbonization rate of 0.42 per cent C per hour to be attained, as against 0.14 per cent C per hour with no oxygen, and 0.35 per cent C per hour delivering the oxygen vertically on to the bath.

Title: Improvements in or relating to a motor road vehicle
Inventor: WEBSTER HENRY GEORGE
IPC: F16H48/30
Filed: 1968-07-31
Abstract: 1,267,808. Controlling motor vehicles. STANDARD-TRIUMPH MOTOR CO. Ltd. 29 Aug., 1969 [31 July, 1968], No. 36429/68. Heading B7H. [Also in Division F2] A motor road vehicle having drivable axles in which one axle or a group of axles is capable of connection to another axle or group of axles is provided with control means for controlling the transmission to the other axle or group of axles in accordance with the degree of actuation of the vehicle brakes, the control means including a coupling for connecting the axles, and means responsive to the application of the brakes for actuating the coupling. In one embodiment (as shown), a coupling 12 with teeth 13 is engageable with teeth 11 on a drive shaft from a main change-speed gear-box, the shaft being connected to front axle gearing. The coupling is carried on a shaft 14 connected via flange 15 to rear axle gearing. A lever 19 is operable to move a member 20 for selecting either two- or four-wheel drive. The control means includes the coupling 12 and an hydraulic cylinder 36 connected to the fluid brake system of the vehicle such that application of the brakes causes a rod 26 to act on member 20 through a spring 27. Spring 27, being stiffer than springs 21, 22 acting between member 20 and an abutment on lever 19, causes member 20 to shift to engage coupling 12 so that both axles are driven. Had four-wheel drive previously been selected by lever 19, operation of the brakes would have no effect on the coupling 12. The control means is actuable only after a predetermined degree of application of the brakes has been accomplished, due to the opposing action of a spring 38 in cylinder 36. In a second embodiment (Fig. 2, not shown), the coupling is arranged to be engaged by application of a hand brake, while in a third embodiment (Fig. 3, not shown), the coupling is arranged to be engaged by application of either a hand brake or a foot brake. In a modification (not shown), the coupling is constituted by a multiplate friction clutch.

Title: Process for retarding the evaporation of organic liquids
IPC: B01J19/16
Filed: 1963-09-17
Abstract: Premature evaporation of a solvent or solvents from an exposed composition, e.g. a floor wax, shoe-cream, cleaner polishing agent, lacquer or varnish is retarded by incorporating a partial ester of a di- or poly-glycerine and a monobasic fatty or hydroxy fatty acid (at least 8 C) in an amount within the range 0.1 to 10% by weight based on the solvent, of a composition comprising one or more non-volatile components and a major proportion of the volatile organic solvent or solvents.  Solid hydrocarbons, hard or soft paraffins, ozokerite, crude or oxidized montan wax, stearin, ceresin, an ester or salt of montan wax, a ketone of a fatty acid, polyethylene, polypropylene, polybutylene, polyvinyl butyrate, a polymer based on acrylic or methacrylic acid ester, polyacrylonitrile, a polyester, a polyamide, a polyester amide, an alkyol resin, a glyptal resin, a synthetic or natural rubber or a natural resin may be the non-volatile component present.  Fatty acids to form the partial ester are those derived from coconut oil, and palmitic, stearic, montanic, oxystearic, oleic, linoleic, or linolenic acids, and may be modified by a polybasic acid or anhydride. Many solvents are listed and the composition may include a solid filler and/or pigment. An example describes the addition of a di-glycerin-monostearate further esterified with adipic or phthalic acid, to a black shoe cream containing partially esterified montan wax oxidized with chromic acid, ozokerite, paraffin wax, turpentine, white spirit, and nigrosine base, to reduce the solvent loss.

Title: Improvements in and relating to suction lifting equipment
Inventor: STRETTON HENRY JACKSON
IPC: B66C1/02
Filed: 1959-10-29
Abstract: 923,724. Suction lifting devices. G. D. PETERS & CO. Ltd. Oct. 31, 1960 [Oct. 29, 1959], No. 36786/59. Class 78 (4). In a suction lifting apparatus the vacuum in the pads 3 is released by a valve 21 which opens in response to differential air pressure produced when the pads are disconnected from a vacuum reservoir 11. The pads are connected to the reservoir 11 by an electromagnetically operated valve 19 controlled by push-buttons 32. When the valve member 27 is in its upper position the reservoir 11 is connected to pads 3 through pipes 17a, 17, 23 and 5. A constriction 24 in the pipe 23 produces a drop in pressure in a chamber 14 which moves a diaphragm 16 and the valve 21 upwards to allow suction to develop in the pads 3. Once the valve 21 is closed it is held closed by reduced pressure in a chamber 15. To release the vacuum, the valve member 27 is moved to the position shown to connect the pipe 17 to atmosphere through a pipe and filter 29, 30. This causes an increase in pressure in the chamber 14 which moves the diaphragm 16 and the valve 21 downwards, thus admitting air to the suction pads. The opening movement of the valve 21 is aided by gravity. A micro-switch 31 actuated by the valve 21 ensures that a motor 10 runs continuously to maintain a vacuum when an article is being lifted. At other times a pressureresponsive switch 25 controls the motor 10. When the vacuum in the suction pads reaches a value at which the load may be lifted in safety, a pressure-responsive switch 35 extinguishes a red light and lights a green one. The constriction 24 by preventing a sudden change in the vacuum pressure when suction is first applied to the pads ensures that the green light will not light up prematurely. To prevent rotation during lifting, the whole apparatus is suspended from a hoist mechanism by a rope which passes under two horizontallyspaced pulleys mounted thereon. The apparatus can be steered during lifting by a handle 42. Specifications 830,393, 830,394 and 876,370 are referred to.

Abstract: 827,178. Colour Television tubes. CHROMATIC TELEVISION LABORATORIES Inc. Dec. 23, 1955 [Dec. 28, 1954], No. 36888/55. Class 39(1). A pattern of colour phosphors is formed by exposing a base plate coated with photographic emulsion to a scanning electron beam which has been subjected to substantially the same focusing and deflecting fields as the scanning beam of the colour raster and to an additional deflection or defocusing to make the beam width equal to the desired phosphor width. A conventional C.R.T. 10 comprises a demountable vacuum system with a flange 22 supporting a base plate 16 and the two colour grids 20, a cover plate 18 forming an airtight seal with the flange and a tube 24 serving to exhaust the C.R.T. A phosphor coated base plate 16 visible through the cover plate 18 is scanned by the beam and adjustments made to obtain the appropriate scanning raster, the plate 16 being replaced by one coated with an emulsion sensitive to electron bombardment and comparatively insensitive to light and with a conductive layer 19, e.g. aluminium. A dye may be added to the emulsion. After evacuation and exposure, the plate is removed and developed in an alkaline bath, to remove the metal layer and in a photographic developer to form a master printing plate. During exposure, the beam is over- and under-focused and deflected to give a width of exposure greater than the beam width. A magnetic deflector coil fed with variable current will cause the beam to oscillate over the target as will alternating deflecting voltages applied to the grid wires 20. The developed plate is utilized for printing the phosphor pattern. In a modification the phosphor may be included in the phosphor sensitive material, a method particularly applicable to curved screens.
