Title: Improvements in or relating to the manufacture of polymeric materials
Inventor: CHAPMAN JOHN FREDERICK
IPC: C08J9/14
Filed: 1962-08-13
Abstract: Foamed polyurethane materials are manufactured by the interaction of an organic polyisocyanate with a hydroxyl group containing polymer in the presence of a halogen-substituted hydrocarbon of low boiling point by a process which comprises the steps of incorporating a gaseous halogen-substituted hydrocarbon having a boiling point between - 50 DEG  C. and 50 DEG C. at atmospheric pressure in a hydroxyl group containing polyester, polyesteramide or polyether and then reacting the hydroxyl group containing polyester, polyesteramide or polyether with an organic polyisocyanate optionally in the presence of water. Particularly suitable halogen substituted hydrocarbons are those which contain at least one fluorine atom per molecule, particularly monofluorotrichloromethane. In the examples there are utilized polyethers prepared by the reaction of propylene oxide with triethanolamine, sorbitol or trimethylolpropane. The reaction mixture may also include catalysts, particularly tertiary amines and organic compounds of metals, surface-active agents such as oxethylated phenols and fatty alcohols, block copolymers of ethylene and propylene oxides, silcone fluids and particularly siloxano-oxyalkene block copolymers and other additives such as cross-linking agents, foam-stabilizing agents, colouring matters, fillers, plasticizers, flame retardents and antioxidants.

Title: Improvements in or relating to poisons for destroying insects and the like
IPC: A01N25/26
Filed: 1945-11-20
Abstract: An insecticide comprises particles of a toxic substance, which is not repellant to insects and which is lethal to a number of different kinds of insects including Hymenoptera, coated with a protein or polysaccharide which is insoluble in water and in the alimentary tracts of Hymenoptera, but soluble in the alimentary tracts of leaf-eating or wood-eating insects.  Specified toxic substances are 4, 41-dichlordiphenyl - b , b , b  - trichlorethane and g -benzene hexachloride.  Liquid toxic substances may be absorbed in an inert carrier.  Suitable proteins are zein, or water-soluble proteins, such as casein, gelatin or a degraded gelatine such as a size which has been insolubilised by treatment with formaldehyde, with or without the addition of sulphuric acid and salt, benzoquinone or potassium dichromate, or with certain proteins such as casein by conversion to an insoluble salt.  The polysaccharide may be a degraded form of cellulose produced by dissolving ordinary cellulose in one of the known agents, e.g. ammoniacal cupric chloride and bubbling oxygen through the liquid.  The degraded cellulose can then be precipitated on the particles of toxic agent, for example by the addition of hydochloric acid.  Protein coatings can also be applied in an essentially similar manner provided solutions thereof can be made in a liquid in which the toxic agent is insoluble.  The protein may be rendered insoluble after the coating has been applied.  The solvent is preferably removed by spray drying.  The Provisional Specification describes also dinitro-o-cresol, dinitro-cyclohexyl-phenol, tetra-nitro-carbazoles and the hexa ethyl ester of tetraphosphoric acid as suitable toxic substances.

Abstract: 830,198. Road vehicle spring suspensions. FORD MOTOR CO. Ltd. (Ford Motor Co.). Oct. 8, 1957, No. 31458/57. Class 108(2) An independent suspension comprises a torsion bar 34 in splined connection with a pivotally mounted support 32 on the frame 11, and in splined connection at its other end with a member 38 (Fig. 4). The latter is rigid with a control arm 36 which is pivotally connected at its other end to a transverse tubular frame member 16. The axis of the pivot of the connection between the arm 36 and the member 16 passes through the centre of a universal joint 22 on the road wheel drive shaft 23 and the centre of the joint between the torsion rod 34 and the support 32 on the frame 11. The member 38 carries a horizontal outwardly extending pin 42 on which is rotatably mounted a shackle 54 carrying a forwardly extendng horizontal pivot 63 on which the wheel supporting member 27 is mounted. A telescopic strut 66, which may comprise an hydraulic shock absorber, is rigid at its lower end with the wheel supporting member 27 and is pivotally connected at its upper end to the vehicle frame. The axial position of the end of the torsion bar 34 may be adjusted relatively to the member 38 by rotaton of a nut 48 secured by a bolt 51. The axes of the pivots 42 and 63 may be inclined at an angle which is not a right angle. U.S.A. Specification 2,757,747 is referred to.

Title: Control Apparatus for the Powered-Lifter Installation of an Agricultural Tractor.
IPC: A01B63/112
Filed: 1967-07-07
Abstract: 1,182,973. Change speed control. KLOCKNER-HUMBOLDT-DEUTZ A.G. 7 July, 1967 [21 July, 1966], No. 31487/67. Heading F2D. [Also in Division A1] In a tractor power lift mechanism (see Division A1) control signals dependent on the speed of the tractor are derived from a governor 85 in the automatic gear-box of the tractor. The output shaft 19 is driven by the tractor engine via a torque converter 3 and gear-box 9 of the intermeshed planet type providing three forward ratios and one reverse. For gear I a clutch 10 is engaged to drive a sun-wheel 14 which transmits drive through planet wheels 16, 17 and a ring gear 18. The planet carrier 20 is held from reverse rotating by a one-way brake 21, which has a parallel two-way brake 22 for use in B setting of a manual selector valve 77. For gear II clutch 10 is engaged and brakes 24, 26 operate to hold shaft 13 stationary so that the planet carrier 20 is free and the ring gear 18 is driven with increased speed. For gear III both clutches 10, 11 are engaged to lock shaft 12 in rotation with shaft 13. For reverse clutch 11 is engaged and brake 22 operates to hold the planet carrier 20 stationary. Clutch and brake control circuit.-Pump 57 supplies pressure fluid to chambers 65, 66 of a main pressure valve 67 from whence fluid flows to a selector valve 77, a blocking valve 75 and a control throttle pressure valve 78. The selector valve has a park position P an automatic position A for freewheel operation, an automatic position B for engine braking, a neutral and reverse position. In both positions A and B of the selector valve pressure fluid is directed to conduit 80 to operate clutch 10 and is also directed to valve 84 controlling the change between gears I and II and to the governor 85 which produces a pressure in the conduit 86 in dependence on the tractor speed. This latter pressure is applied to cylinder 89 of valve 84 and also to cylinder 87 of valve 88 controlling the change between gears II and III. The difference in diameter of control pistons 94, 93 of these valves allows valve 88 to remain in its neutral position whilst valve 84 operates to change gear. On increase in speed the governor 85 increases the pressure in conduit 86 to cause valve 88 to change to gear III. In positions B and R of the selector valve pressure fluid is supplied via conduit 76a to conduit 120 feeding the control throttle pressure valve 78 whereby fluid is supplied to the converter pressure valve 128 to shift piston 127 to close the passage to sump at 129. Fluid is thus supplied via conduit 118 to move piston 69 of the main pressure valve 67 to connect the supply branch 63 to the converter 3 to couple the engine to the shaft 7. It is stated that, since the converter pressure is automatically adjusted by the valves 78 and 128 in dependence on the driving torque of the engine, the converter characteristic is adapted automatically to the attached load.

Abstract: 335,756. Buchi, A. Nov. 3, 1928, [Convention date]. Regulating. - In engines supplied with air charge by compressors driven by exhaust turbines, the pressure in the exhaust pipe between the engine and turbine is periodically lowered by opening a bye-pass valve to the whole or part of the turbine. The valve may be worked by a cam on the engine shaft and open a bye-pass to the atmosphere. The valve may be controlled by the pressure of the exhaust air, or as shown the valve 18 is controlled by a piston 27 subject on its upper side to the pressure of the exhaust and on its lower side to the air pressure and a spring. In this arrangement the bye-pass leads to a second stage 23 of the turbine 12. Specification 262,106 is referred to. The Specification as open to inspection under Sect. 91 (3) (a) also states that the control of the valve 18 may be effected by the compressed air alone. This subject-matter does not appear in the Specification as accepted.
