Title: Improvements in vehicles
IPC: B62D7/00
Filed: 1938-11-11
Abstract: 521,280. Motor vehicles. MACHRAY, G., and DAVEY, J. Nov. 11, 1938, No. 32831. [Classes 79 (iii) and 79 (v)] An electric or other motor vehicle is provided with a substantially vertical tiller 8 pivotably mounted at its lower end so as to move in a transverse plane for steering the vehicle, in a longitudinal plane to control the brake, and having a knob 16 or the like for controlling the power switch of the driving motor or engine. In the construction shown the steering wheels 3 swivel on posts 2 and are controlled by a cable 6 passing through guide tubes 8<SP>1</SP> or over pulleys to a quadrant 7 to which it is secured, the quadrant being oscillatable about a longitudinal axis of the vehicle. The quadrant is rocked to steer the vehicle by the lateral movement of a tiller 8 carried by the quadrant. The tiller is pivoted at 9 to the quadrant and backward and forward movement of the tiller about the pivot controls a brake on the driving wheel 12 through a link 10. The tiller can be locked in position with the brake applied by means of a pawl 19 pivoted at 24 and adapted to engage a segmental rack 29 on the quadrant 7. The pawl is released by pressing on a spring-loaded knob 16 in the tiller handle. When the tiller is in the brake-released position shown depression of the knob 16 rocks the pawl 19 until a lug 21 thereon operates the plunger 25 of a switch 26 and energises an electric motor 13 driving the wheel 12, when the knob is released the switch 26 is opened by a spring. A stop 28 on the rack 29 is engaged by the end 27 of the pawl 19 and prevents the tiller from being moved to apply the brake while the pawl is holding the motor switch closed. The stop 28 also prevents the pawl from being rocked to close the motor switch while the tiller is in a braking position. The pawl may be used to control an internal-combustion engine driving the vehicle instead of an electric motor.

Patent GB-980021-A (GB)
Title: Production of polymers
Inventor: FISHBEIN JOHN
IPC: C08G18/48
Filed: 1960-09-27
Abstract: A process for the production of a polyurethane prepolymer comprises reacting in the presence of a catalyst an organic polyisocyanate or polyisothiocyanate with a polymer of an alkylene oxide which when first formed has terminal secondary hydroxyl groups but in which these groups have been reacted with ethylene oxide.  Little or no heating is necessary in the preparation. The prepolymer may be converted to a foamed material by addition of water and catalysts. Catalysts specified for the prepolymer formation are tertiary amines, preferably triethylene diamine, and esters, alkyl esters and salts of metals of Group IV, V and VI of the Periodic System.  For the foaming step trimethylamine, triethylamine, N-methylmorpholine, N-ethylmorpholine, dimethylbenzylamine and organometallic compounds are suitable catalysts.  Silicone oils and water-soluble copolymers of polydimethyl-siloxane and alkylene oxides may also be added.  The polymer of alkylene oxide may be a linear polymer of propylene or butylene oxide or may alternatively be a copolymer of these oxides with a polyhydric alcohol such as glycerol, hexanetriol or trimethylol propane. These polymers, containing terminal secondary hydroxyl groups to replace such groups by terminal primary hydroxy groups.  Preferably the addition of not less than 1 and not more than 4 ethylene oxide units to each hydroxyl group of the initial propylene or butylene oxide polymer or copolymer is effected.  In examples (1) a prepolymer is prepared by mixing an ethylene oxide tipped, glycerol-centred propylene glycol of M.W. 3000, triethylene diamine and a mixture of tolylene-2,4 and 2,6-diisocyanates which is reacted in three portions; (2) a foamed product is obtained when the prepolymer is mixed, in a continuous foaming machine, with a silicone oil and an aqueous solution of N-methylmorpholine and triethylamine.

Title: Improvements in or relating to control systems
Inventor: HOLMES FRANK RICHARD
IPC: G05D3/12
Filed: 1954-11-18
Abstract: 774,923. Electric control systems. POWER-GAS CORPORATION, Ltd. Nov. 18, 1954, No. 33412/54. Class 40 (1). A blast furnace blast pressure relief or other valve is operated through a servo-system by a remote positioning element which upon failure of the servo-system operates the valve directly. As shown, rotation of a screw 5 by a hand-wheel 1 in either direction moves a nut 6 along the screw to close one or other of limit switches 8 whereby a servomotor 10 is driven in one direction or the other, according to the switch 8 which is operative, and through gearing 40 a magnetic clutch 9, shaft 11, reduction gearing 13, and a crank 2 operates the valve (not shown). A drum 14 rigid with the driven shaft 11 is coupled by a cable 15 to the nut 6 which is thereby rotated in such a sense as to break the operative limit switch 8. The motor 10 thus drives the valve operating mechanism as long as the operative limit switch 8 is kept closed by continuous rotation of the handwheel 1. At the limit of travel of the valve, limit switches 16 cut out the motor. Should the servo-drive fail, continued rotation of the handwheel 1 causes the nut 6 to engage one of the thrust bearings 7 whereupon the nut rotates with the handwheel and sets the valve through the cable 15. The magnetic clutch 9 is engaged at the same time as the motor 10 is switched on, so that in the event of supply failure the motor is disconnected from the shaft 11 during manual control. The position of the valve may be indicated by a pointer 20, Fig. 2, driven through gearing from the handwheel shaft 3 or from the nut 6 and a further pointer 30, operated through a bell crank 34 from the limit switch operating levers 32 indicates whether the valve is at rest or being opened or closed. A fluid-operated servomotor may be used.

Title: Method and plants for obtaining precipitates easy to separate from the liquid medium
IPC: B01J19/00
Filed: 1945-12-11
Abstract: In the formation of a precipitate by reacting a solution with a solid, liquid or gaseous reagent by a process such that the reagent is directly and readily soluble, i.e. without chemical transformation, in the reaction medium and thereafter is able to react directly with the solution to form the precipitate, both the reacting substances are introduced progressively and at every moment approximately in the proportion required for the reaction with constant stirring into an empty or partially empty vessel (which may contain a quantity of precipitate from a preceding reaction) until the vessel is full; or are introduced in the same manner into each of a plurality of such vessels inter-connected one with the other so that the precipitates flow successively from p  one to the other, in order to obtain a dense precipitate adapted to be easily separated from the residual liquid medium.  A chemically insert liquid or a part of the mother liquor from a preceding operation or from the operation in progress or the resulting precipitate may be added to dilute the reacting ingredients.  Examples describe the precipitation of barium sulphate by reacting solutions of sodium sulphate and barium chloride, the precipitation of magnesia by the action of lime-water or sea-water, and the precipitation of alumina by the action of carbon dioxide on a cold solution of sodium aluminate.
