Abstract: 778,606. Carburetters. FORD MOTOR CO., Ltd. March 5, 1956 [March 3, 1955], No. 6874/56. Class 7 (3). A cam or lever 16 on the spindle of the starting carburetter throttle cooperates with an arm 14 carried by a lever 12 on the spindle 13 of the main throttle valve 11 so that the main throttle valve is opened at least slightly when the auxiliary carburetter is being switched out of use. As shown by Fig. 4 the main throttle valve is opened when the cam 16 is in an intermediate position. The main throttle may be in idling position if the starting carburetter is switched in or off. It can be arranged that if the starting carburetter is fully switched in the main throttle valve 11 is fully closed whereas with the starting carburetter switched off the main throttle valve is brought into a certain predetermined open position. Preferably the main throttle valve is adapted to be closed when the auxiliary carburetter is in use and at least slightly opened when out of use.

As shown the lining 16 is built up successively of side by side longitudinal segments each formed by moving the slinger machine backwards and forwards along the support beam 3. Alternatively the lining may be built up of annular sections by rotating the tubular vessel 1 through 360 before changing the axial position of the slinger machine 5 within the vessel. The slinger 5 includes a slinger wheel driven by a motor 7 and a wheel track 8 driven by a separate motor. The lining operation is controlled from a desk 21 with the aid of a television camera 22. An adjustably mounted milling machine 23 is provided to smooth the surface of the lining if necessary. The lining material, which may comprise clay bound bauxite, mullite or corrundum compound is fed to the slinger machine 5 by means of a first conveyor 9 disposed in an elongate supporting structure 10 and a further conveyor 15. The structure 10 is securely connected at one end to the slinger 5, while its other end is free to move backwards and forwards on a roller track 11.

Title: Improvements in or relating to printing inks
IPC: C09D11/02
Filed: 1950-03-22
Abstract: Unsaturated non-aromatic hydrocarbons containing at least 3 carbon atoms are subjected to conjunct polymerization in the presence of an acid acting catalyst to yield a conjunct polymer having drying oil properties containing on the average at least 2.5 olefinc double bonds per molecule, and having a bromine number of at least 140. Suitable starting materials are polyolefins such as butadiene, and the unsaturated hydrocarbons, primarily octene to dodecylene olefines, produced by the catalytic polymerization of propylene and butylenes.  Acid acting catalysts specified are the Friedel-Crafts metal halides such as aluminium chloride and bromide and mineral acids such as sulphuric and hydrofluoric acids.  Conjunct polymerization is carried out at temperatures of -30 DEG  to 200 DEG C., and the polymer-catalyst sludge is separated from the saturated hydrocarbon and decomposed, either hydrolytically or thermally, to yield the conjunct polymer.  The product consists of polyolefinic cyclic hydrocarbons containing conjugated and non-conjugated unsaturation.  In a modification of the process the olefinic hydrocarbons are copolymerized with a drying oil in the manner described above.  The products of the process are employed as printing ink vehicles.ALSO:Unsaturated fatty acid esters capable of oxidative drying are associated with a hydrocarbon conjunct polymer containing on the average at least 2.5 olefinic double bonds per molecule, and having a bromine number of at least 140, which is formed by the conjunct polymerization of an unsaturated non-aromatic hydrocarbon, containing at least 3 carbon atoms, in the presence of an acid-acting catalyst.  The unsaturated fatty acid ester may be associated with the conjunct polymer by mixing, by cobodying, or by copolymerizing the unsaturated fatty acid ester with the hydrocarbon monomer.  Unsaturated fatty acid esters specified are tung, linseed, dehydrated castor, oiticica, perilla, soyabean, hempseed, poppyseed, safflower and walnut oils, or synthetic esters of fatty oil acids wherein the glycerin is replaced by an alcohol such as methanol, ethanol, a glycol, a polymeric glycol, pentaerythritol, polyallyl alcohol, 2, 2-dimethylpropanol, or butenol.  The products are employed as printing ink vehicles in conjunction with pigments, fatty oils, natural or synthetic resins, extenders, and wetting agents.

Abstract: 1428632 Indicating low pressures in vehicle tyres NISSAN MOTOR CO Ltd 18 Feb 1974 [20 Feb 1973 16 March 1973] 7270/74 Heading B7C [Also in Division H1] A pressure sensitive switch for indicating loss of pressure in a vehicle tyre comprises a casing 11, Fig. 3, containing a diaphragm 17 subjected to the tyre air pressure on one side balanced by an adjustable compression spring 18 on the other side. The diaphragm is coupled to a conductive slider 24 movable in an insulation guide 25 and carrying a snap-action resilient spring strip 30 having a movable contact 29, mounted on each end for normally engaging a pair of fixed contacts 28 on the conductive housing at normal tyre pressures. A circuit to connector 21 is completed through the spring 18. The spring strip 30, Fig. 5 comprises a pair of central compression legs 30c extending towards each other to engage opposed groove 24a in the slider 24 at their inner ends and arranged between a pair of corrugated tension legs 30a of the strip 30. The switch is mounted on the vehicle wheel rim whereby the centrifugal force on the slider 24 assists the spring 18 at speed to increase the pressure at which the switch responds. In a modification the contacts are arranged in a chamber which is sealed by a further diaphragm (31), Fig. 7 (not shown), to prevent ingress of dirt, moisture &c. and may contain an inert gas. The fixed contact 28 may also be carried on bimetal cantilever arms to obtain temperature compensation. The signal from the switch is transmitted from a coil mounted on the wheel to a stationary coil on a fixed part of the wheel support.

Title: Improvements in or relating to gyroscopically-controlled automatic pilot devices
IPC: G01C19/00
Filed: 1942-05-30
Abstract: 558,426. Automatic control systems for aircraft. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd., and SIMPSON. L. M. May 30, 1942, No. 7371. [Class 38 (iv)] Steering.-Uncontrolled precession of a gyroscopically controlled automatic pilot is corrected by an instrument which is power-driven to follow a magnetic compass. The correcting device controls the admission of operating fluid to the automatic pilot to cause precession in the same way as it would be controlled by a manually operated device determining the course to be followed. When the course deviates more than ¢ degree from that indicated by the position of lines 18, 19 on a preset disc 12, a contact segment 20 rotated by the element 11 of a compass repeater operates a short circuit on one or other of two relays A, B and causes dimming of one or other indicator lamp 25, 26. The operated relay, say A, energizes at a<SP>3</SP> a clutch magnet 30 and at a a reversible motor 31. The magnet 30 depresses a lever 40 whereby the motor is clutched to pulleys 32, 33, coupled by Bowden cables to pilot and bombaimer controls, causing precession of the gyroscope of the automatic pilot to alter course in a correcting sense. The magnet also presses a roller 35 on to cams driven with the pulleys so that if the motor should run long enough to give a maximum correction, determined by the angle covered by the relatively adjustable cams, the roller will be further moved to open a switch 39 and stop the motor, at the same time engaging the end of the cam to lock the control against return, by the usual springs in the pilot and bombaimer's controls, until the relay has been deenergized by full correction of course. To ensure correcting action when the disc 12 is displaced 180 degrees a contact 45, operative only in this condition, energizes a relay C to effect control movement similar to that of relay A until one or other of the relays A, B becomes effective. The movement of the pulleys causes opening of one or other of two fluid pressure valves causing precession of the gyroscope but in a modification these valves may be in steering control pipe lines and operated directly by the relays.
