A forked stirrup 13 engages with the bearing of the cable pulley 10 and a stirrup 13b engages pivotal lever 11b at a point spaced from the cable pulley 106. The stirrups 13, 13b are connected to actuation cable wires, forming a common actuation cable 14, which is led over a pulley 10d. The pulley 10d is connected to an actuation mechanism via an actuation cable 14d in which a tension lock or stretching screw or tie bar 15 is inserted or via a brake rod. On pulling the cable 14d, the force exerted thereon is distributed over the brakes of axles 2, 2a in a predetermined ratio according to the points of application of the stirrups 13, 13b; the brakes 5, 5a and 5b, 5c are respectively actuated with equal force owing to the pulleys 10, 106.

A press, particularly a mechanical coldextrusion press, has an ejector 8 operated by oil pumped by the movement of the press ram. The latter is connected by rods 2 to a crosshead 3 carrying two plungers 4 working in cylinders 5. Ejector 8 is connected to a piston working in a cylinder 14. During the return stroke of the ram, the plungers 4 move inwardly to force oil out of cylinders 5. A valve 12 controls this flow to the ejector cylinder 14 or to a reservoir 13. A stop 10 adjustable by a bevel wheel 11 limits the stroke of the ejector and thereafter an overload valve opens to release pressure cil to the reservoir. Valve 15 releases oil from the ejector cylinder to the reservoir and the ejector is then retracted by spring 9. Valves 12, 15 may be controlled by cam-actuated switches on the drive shaft of the press ram.

Abstract: 1,222,985. Coated sheet material. ARTHUR D. LITTLE, Inc. 10 May, 1968 [15 May, 1967], No. 22396/68. Heading B2E. A high gloss coating may be formed on a fibrous substrate by (a) forming an oil-in-water emulsion comprising an aqueous dispersion of a film-forming binder material as continuous phase and a water-imiscible volatile liquid which is essentially a non-solvent for the binder material as discontinuous phase and which has a boiling point which is not less than that of water, the binder being susceptible to moulding under heat and pressure and capable of forming an opaque film in the form of a bubble structure, substantially all the globules of the water-imiscible liquid in the emulsion being no greater than 1 micron, (b) applying a film of said emulsion to the surface of a substrate, (c) stabilising the structure of the applied emulsion film by evaporating first a portion of the water of the emulsion and forming a matrix of film-forming binder material having distributed throughout minute globules of water-imiscible liquid, the dimensions of which remain substantially the same as those of the continuous phase in the emulsion film, (d) evaporating substantially all of any remaining water from the matrix and evaporating the water-imiscible liquid and the globules to provide multitudinous air-binder interfaces to create a broken bubble structure within the essentially continuous film, substantially all of the interfaces being no greater than 1 micron in dimension so that there is formed a bright, opaque coating on the substrate, (e) treating the surface of the coating to superficial smoothing of the surface without essentially altering the bubble structure and (f) calendering the resulting surface at a elevated temperature at at least 100 lbs. per linear inch to form a high-gloss coating, the conditions of the calendering being such that the bubble structure is not substantially destroyed. The substrate may be a bleached sulphite web. The coating may be by means of an air-knife. Finely divided particulate material may be present in a coating layer, for example, titanium dioxide. The binder may be a protein, such as casein, soya protein, zein, animal glue or gelatines, waterdispersable elastomers such as natural and synthetic rubbers, water-soluble, film-forming synthetic resins, e.g. polyvinyl alcohols, and water-dispersable thermoplastic resins, e.g. polyacrylates, polyvinylacetates, and chlorides, copolymers of vinyl acetate and vinyl chloride, of vinyl acetate and ethylene and copolymers of acrylates.

Filed: 1973-05-11
Abstract: 1436892 Automatic control of lifts WESTINGHOUSE ELECTRIC CORP 11 May 1973 [24 May 1972] 22486/73 Heading G3N [ Also in Divisions G 1 and H 1] The acceleration of a D.C. motor is determined by measuring the rate of change of armature current, using a transformer 60 Fig. 1 whose core 68 is wound with a first winding 62 carrying the armature current of the motor 12, a second winding 64 carrying a fixed current produced by the armature voltage, and a third winding 66 acting as a pick-up winding. The circuit of the second winding 64 is such that the ripple flux it produces in core 68 is equal and opposite to that produced by winding 62. Hence the voltage VST induced in the third winding 66 is due to the change in back emf of the armature 14 and is therefore proportional to motor acceleration, and substantially free of ripple. Constructional details of transformer 60 are described, wherein winding 62 is effectively less than one turn. The acceleration signal may alternatively be derived by differentiating the output from a hall plate element. The motor 12 is used in an elevator system, the speed command signal V SP  being supplied by a program 50 and compared with the actual speed signal VT derived from a tachogenerator 52 to produce an error signal VE to which the acceleration signal VST is added to provide an anti-bunting facility.
