Title: Improvements in or relating to petrol-resistant coating compositions
Inventor: MAYNE JOHN EDWIN OAKLEY
IPC: C08F220/18
Filed: 1960-02-12
Abstract: A liquid surface-coating composition comprises a solution of a terpolymer of methyl methacrylate with from 8 to 40% of ethyl acrylate and from 0.2 to 5% of an unsaturated acid, or anhydride thereof, of the formula RCX=CY.COOH wherein R represents a hydrogen atom or a methyl group, X represents a hydrogen atom or a carboxyl group and Y represents a hydrogen atom of the group CH2. COOH, the percentages being calculated on the weight of the final terpolymer. In a modification of the composition the ethyl acrylate is replaced wholly or in part by a percentage H of another acrylic ester of an aliphatic or alkoxyaliphatic monohydric alcohol containing up to 10 carbon atoms and having a maximum chain length of 6 carbon, or carbon and oxygen, atoms, calculated from the formula <FORM:0942947/C3/1> in which A is the percentage of ethyl acrylate to be replaced and M is the molecular weight of the alcohol of the replacement ester. In the terpolymer, up to 10% by weight of the methyl methacrylate may be replaced by an equal amount of a monomer such as styrene, acrylonitrile or ethyl methacrylate.  The compositions are obtained by polymerising the monomers in solution in toluene in the presence of benzoyl peroxide as a catalyst. Half the quantity of catalyst is used initially, and the remainder half way through the reaction time. Specified copolymers are those of methyl methacrylate and ethyl acrylate with acrylic acid, itaconic acid and maleic anhydride.

Title: Improvements in or relating to drawbenches and like apparatus
IPC: B21C1/30
Filed: 1944-03-20
Abstract: 572,497. Drawing. NORTHERN ALUMINIUM CO., Ltd., and SHEPHERD, L.G. March 20, 1944, No. 5159. [Class 83 (iv)] A draw-bench carriage is provided with means for cushioning the end of the return stroke and for ensuring that the tongs grip the work securely at the start of the next drawing operation. A roller 7 on the carriage engages the slotted end of a lever 1 pivoted at 3, towards the end of the return stroke. The lever is linked to a cross-head 10 on the rod 12 of a piston 13. Escape of air from behind the piston is controlled by an adjustable needle valve 15 according to the amount of cushioning desired. During movement of the lever 1, an adjustable cam 16 on it operates a lever, allowing an exhaust valve 18 for the other end of the cylinder 14 to close and opening a pressure supply valve 19. Pressure air does not, however, pass until a treadle-operated valve 24 is also opened. The carriage comes to rest with the lever 1 resting against a spring buffer 22, and the valve 24 is now operated, admitting air at 25 to means for pushing forward a new tube and mandrel so that the tag end passes through the die. At the same time pressure behind the piston 13 forces the lever 1 and consequently the carriage further back towards the die, compressing the buffer spring and bringing the trip rod 26 for the hook into contact with a stop 27, thereby permitting the hook to engage the chain. The drawing stroke of the carriage commences against the resistance of the lever 1 due to the air pressure in. the cylinder 14 and this ensures that the tongs take an immediate grip upon the tube. The carriage is constructed as described in Specification 572,429.

Title: Vehicle Suspension Strut.
Inventor: WADDLETON NORMAN
IPC: F16F9/48
Filed: 1968-02-02
Abstract: 1,176,627. Fluid springs. CATERPILLAR TRACTOR CO. 2 Feb., 1968, No. 5378/68. Heading F2S. In a vehicle suspension strut employing a gas spring, the spring rate is automatically modified according to the load by changing the effective gas volume. The strut consists of a piston and cylinder and the gas is contained in three chambers, viz. the cylinder space A on one side of the piston, a space B within the piston and a reservoir 25 outside the cylinder. The means for changing the effective gas volume is a sliding valve element 37 which, as the piston advances, can isolate space B and/or reservoir 25 from the cylinder space A. Under light loads the gas spring comprises all three chambers. As the piston 15 moves further in, the valve element 37 engages opening 42 and isolates chamber 25. Further compression causes valve 37 to slide, against spring 40, through guide 30 and break the alignment of groove 38 with groove 32 to isolate chamber B. The tube 31 is present to prevent a build up in chamber B of valve-lubricating oil from chamber A. Damping is obtained by oil flow between chambers 18 and 19 via bore 21 and a damping valve 20.

Title: Apparatus for Automatic Arc Spot Welding.
Inventor: WEMAN KLAS BERTIL
IPC: B23K9/007
Filed: 1969-01-31
Abstract: 1,196,725. Arc welding systems. ESAB Ltd. 31 Jan., 1969 [8 Feb., 1968], No. 5399/69. Heading H2H. Apparatus for arc spot welding comprises a device for feeding a consumable electrode to the work and a timing circuit which is controlled by a fast acting switch so that time lost during interruptions of the welding current is compensated for. As shown in Fig. 1, a motor 9 may be energized from A.C. terminals 14, 15 to drive an electrode 1 towards work 4, 5, and welding current is supplied from a source 19 having a three-phase input BST. The timing circuit consists principally of a variable resistor 30 and a capacitor 26. In operation, a manual switch 24 is first closed so that relays C, 21. A and E are successively energized. Relay 21 starts the flow of gas to a shield 6; relay A starts the drive motor 9; and relay E switches on the power source 19. A selector switch 25 has previously been set to a position P; the other position, K, being for continuous welding. When the electrode 1 contacts the work, current flows and a fast relay B closes its contacts and the capacitor 26 begins to charge through resistor 30. After a preset time, this charge will be sufficient to break down a unijunction transistor 33, when the capacitor will discharge and a pulse will trigger a thyristor 38. Current now flows in a relay D which breaks the circuit through relays A and C, so terminating the weld provided the starting switch 24 is released. If the arc extinguishes during welding, the fast relay B will be de-energized and the charging of capacitor 26 will be temporarily halted until the arc is restored, so that the welding time is appropriately prolonged. In a modification, Fig. 3 (not shown), a transistor is added to the timing circuit in such a way that the charging of the capacitor is also halted if the arc is shortcircuited so that the voltage between the electrode and the work falls below a certain level.

Patent GB-846474-A (GB)
Title: Improvements in or relating to the decolorisation and purification of oils and fats
IPC: C11B3/10
Filed: 1957-02-18
Abstract: A process for purifying and decolorizing oils and fats (e.g mineral oils and animal and vegetable fats) comprises subjecting a mixture of the oil or fat and an adsorption agent, for example zinc chloride, decolorizing earth or activated carbon, or mixtures thereof, to a sudden rise in temperature by contact with a p  pre-heated portion of the mixture in a heat exchange contact zone at a temperature below that which will cause polymerization of the oil or fat, generally 140-220 DEG C., and then treating the mixture with superheated steam in counterflow.  As shown, crude oil is fed by pump 2 to tank 1 and thence to mixer 4 where decolorizing earth and activated carbon are added from hopper 5 and zinc chloride solution is run in from tank 7. The mixture is <PICT:0846474/III/1> passed to the upper section 9 of activating column 10 where it is distributed over packing material 11, the pressure in the upper part of the column being reduced by means of condenser and evacuator 13.  On passing to section 14 of the column, the degassed and partially dried mixture comes into contact with hot vapours recycled by pump 15 through high pressure vapour heater 16 (electric heaters or infra red lamps may be used instead), as a result of which the temperature of the mixture rises to 140-220 DEG C.  The mixture passes to lower section 18 where it is subjected to a countercurrent of superheated steam from vacuum vaporizer 20 and high pressure steam heater 21 as it passes through packing 19.  The purified mixture passes from the column to vaporizer 20, where it may be cooled by water to about 70 DEG C., and then to tank 24, before passing to filter press 26 where the impurities and absorbents are removed.  The packing material in the activating column is preferably aluminium.

Title: Fuel feed devices for gas-operated internal combustion engines
IPC: F02M21/02
Filed: 1973-02-05
Abstract: 1402805 Gas carburetters AUTOMOBILES PEUGEOT and REGIE NATIONALE DES USINES RENAULT 5 Feb 1973 [29 Feb 1972] 5519/73 Heading F1B A device, for feeding gaseous fuel to an I.C. engine having an induction pipe, comprises a first means for regulating the flow of gaseous fuel controlled in accordance with the air-flow through the induction pipe and a second means for regulating the flow of gaseous fuel connected in series with the first means and controlled in accordance with the depression prevailing in the induction pipe, the first regulating means comprising a first closure member rotatably mounted in a body in the fuel flow-path, the angular position of this first closure member varying in accordance with the air-flow in the induction pipe, the second regulating means comprising a second closure member mounted in the body and co-operating with the first closure member for totally interrupting the flow of gaseous fuel or effecting a correction of this flow in pre-determined conditions of operation of the engine. Gaseous fuel from a pressure reducer 1 at the outlet of a liquefied gas reservoir is led by a pipe 2 to an annular space 3 around Venturi 4, formed in induction pipe 5, upstream of an operator controlled throttle valve 6. An electrically controlled valve 8 is connected to a pressure sensor 9 open to a port 11 in the induction pipe wall. When the absolute pressure in the induction pipe falls to a value which is less than that at idling, the sensor completes an electrical circuit and closes valve 8, so that the fuel supply is cut-off during over-running. As the engine speed decreases, the absolute pressure increases to the idling value and the valve 8 re-opens. In an alternative construction Fig. 3 (not shown) the pipe 2 ends in a diffuser situated downstream of the throttle valve, and upstream of valve 8 is a rotary valve which is mechanically connected to the throttle valve. The second regulating means may consist of two concentric members mounted transverse the gas flow duct 41, Fig. 5 (not shown), the inner member having a partition wall 45 and the outer member having partitions 43. The inner member is mechanically linked to the throttle valve and the outer member is actuated by a diaphragm subject to induction pipe depression, so that during overrunning the partitions 43 and 45 co-operate to completely stop or to modify the rate of gas flow.
