Abstract: 500,275. Disc brakes. BERGISCHE STAHLINDUSTRIE. May 3, 1937, No. 12562. Void. Convention date, May 7, 1936. [Class 103 (i)] A disc brake comprises a pair of brake shoes arranged to be applied to a rotating disc by a pair of levers the ends of which are spread apart for this purpose by interengaging helically toothed members on a rotatable shaft at least one of the members being movable axially on the shaft automatically to effect adjustment for wear of the shoes. Shoes n, for application to a rotating brake disc v are carried each by a pair of levers i<1>, i<2>, pivoted at k<1>, k<2> on a stationary'bridge piece u. The pair of levers i<1> is connected to pins h<3> projecting at each side of a sleeve h<1> slidable on a shaft c and the pair of levers i<2> is similarly connected to a sleeve h<2> slidable on a part f of the shaft. The sleeves are moved apart axially to apply the brake upon turning the shaft c by a lever b by interengaging helical teeth d<1>, g<2> on these sleeves and on sleeves d, g, the sleeve being directly secured to the shaft and the sleeve g being splined at g<1> to the sleeve d. The part f of the shaft can turn in an extension d<2> of sleeve d and is screwed into the sleeve g at f<2> and it has a ratchet wheel o engaged by a pawl which is actuated by rotation of the shaft c and slips a tooth if there is excessive movement of the shaft due to wear of the shoes, so that during the release movement the shaft f is turned relatively to the shaft c thus displacing sleeve g axially relatively to sleeve d. The pawl is actuated by an arm 8 on a casing t secured to the sleeve g.

Title: Improvements in regulator valves for steam driven locomotives
IPC: F01B25/10
Filed: 1933-05-01
Abstract: 415,857. Valves. OWEN, H., 4, Manor Terrace, Headingley, Leeds, and OWEN, A. E., 107, Palmerston Street, Derby. May 1, 1933, No. 12684. [Class 135.] A lift regulator valve for locomotives has an annular space 6 above the valve seat 5, an aperture or apertures 7 in the wall of this space conveying steam through a small pipe or pipes (not shown) to the cylinders or other parts of the engine for drifting or other purposes when the valve is opened, and a portion of the valve member 3 co-operating with a wall 10 above the space 6 to obturate the main steam passage until the valve has been lifted a predetermined distance. The invention may be applied to a simple lift or poppet valve, or as shown to a double beat valve 2, 3 as described in Specification 204,830, [Class 135], in which the upper member 2 is raised when its wings contact the lower member 3. The member 3 is lifted by a rod 4 operated in the usual manner by rod and crank mechanism from the driver's cab. The upper surface of the wall 10 is inclined downwardly to reduce its axial width. The valve may be located in the usual steam dome or in the smoke box, or at either end of the superheater header in cases where a superheater is provided. When the valve is fitted on the saturated steam side of the superheater, the clearance between the wall 10 and the member 3 allows sufficient steam to pass to the superheater to prevent its elements overheating. The steam from the apertures 7 may also be arranged to close byepass or relief valves or Caprotti valves with which the cylinders may be fitted. The alignment of arrows on a fixed quadrant and on a tail piece fixed to the driver's lever indicates the drifting position. Alternatively, this position may be indicated by the means described in Specification 373,273.

Title: Process for preparing polymer fibres
IPC: D01D5/11
Filed: 1973-03-16
Abstract: 1430796 Polymeric fibres CROWN ZELLERBACH INTERNATIONAL Inc 16 March 1973 [20 March 1972] 12785/73 Heading B5B Polymeric fibres for making paper are produced by forming an emulsion of water dispersed in a polymer in the presence of an emulsifying agent and a solid hydrophilic dispersing aid at autogenous or higher pressure and at a temperature above the melting point of the polymer but below the critical temperature of water, and rapidly passing the emulsion through an orifice into a region of lower pressure to adiabatically vaporize the water and form fibres of polymer. The polymer has a melting- point above the normal boiling point of water. The polymer may be ethylene, propylene, 4- methyl, 1-butene, 1-pentene, pentene-1, vinyl cyelohexane, styrene, nylon-66, polyurethane, or polyethylene terephthalate, or a mixture or copolymer thereof. The polymer may be crystalline and has a melt viscosity less than 500 cp. 0À1 to 20% (by wt. of polymer) of the emulsifying agent is present, and the agent has an HLB value less than 7À0, e.g. calcium or aluminium stearate, cellulose ether, "Span" (Registered Trade Mark), amine salts of alkyl aryl sulphonate or alkyl sulphate, bis-(alkyl)- sulphosuccinate monovalent salts, alkyl aryl polyethyleneglycol, alkyl polyethyleneglycol, and esters of fatty acids. 1À0 to 25% (by wt. of polymer) of the dispersing aid is also included, e.g. bentonite clay, fuller's earth, diatomaceous earth, silica aerogel, or pyrogenic silica. The emulsion normally contains 15 to 45% (by wt. of polymer) of water, and may be formed by blending finely divided polymer (passing through 50 U.S. standard mesh screen) with the other components before heating above melting point, and may be raised to 100 to 1000 p.s.i. above autogenous pressure by nitrogen. The emulsion may itself be dispersed in a quantity of water to form a "dual emulsion". The process may be performed batchwise or continuously.

Title: Electric measuring set
IPC: G01R25/00
Filed: 1951-05-31
Abstract: 692,837. Interrupters. LICENTIA PATENT-VERWALTUNGS GES. May 31, 1951 [Oct. 1, 1948; Oct. 1, 1948], No. 13000/51. Class 38 (v) [Also in Group XXXVI] An instrument for measuring phase difference and also current or voltage comprises a switch operated mechanically by a synchronous motor so as to close its contacts for a portion of each cycle, means for adjusting the period in each cycle during which the contacts are closed, and means for adjusting the instant at which the contacts close in relation to the phase of the energising current. A contact 4, Fig. 1, is closed at regular intervals by an eccentric 7 driven by a synchronous motor 8 and is connected in series with a resistance 2 and a D.C. moving-coil instrument 3 across an A.C. network 1. The contact is arranged to remain closed for a definite time, e.g. one half a cycle of the alternating current in the network 1, in each revolution of the eccentric 7. If the means for displacing the eccentric is provided with a graduated scale the phase relationship between the closing time of the contact 4 and the voltage of the network may be read directly. In the construction shown in Fig. 4, a leaf spring 11 carries the movable contact 12 at one end, the other end being secured to the frame 13. Below the spring 11 is a damping spring 14. A second leaf spring 15 carries the relatively fixed contact, the position of which is adjustable by a screw 16. The shaft 17 of a synchronous motor 18 carries a crank pin 19 which periodically opens and closes the switch by depressing the leaf spring 11. The frame 13 is mounted for rotation concentrically with the axis of the shaft 17 so that the relative angular position of the switch and crank pin and hence the phase position of the switch closing time may be adjusted. By adjusting the screw 16 the closing time of the contacts can, before each measurement, be adjusted to the desired value by means of a D.C. moving coil instrument 20. Fig. 8 shows a device with two contacts 27, 28 driven by eccentrics 35, 36 on the shaft of a synchronous motor 29. The stationary contacts are adjustable by screws 39, 40 projecting through rotatable rings 41, 42 so that the contact time can be altered. Leaf springs 37, 38 carrying the movable contacts 27, 28 are secured to the rotatable rings 41, 42. A scale 43 is fixed to the ring 41, which is surrounded by another ring 45 carrying a pointer 46. Connection to the contacts is made through slip-rings (not shown). Two stops 48, 49 enable either of the rings 41, 45 to be fixed while the other is rotated. The rotor of the synchronous motor may have a high moment of inertia to suppress variations of angular velocity, hunting being suppressed by damping means mounted on the rotor.

Title: Method and apparatus for the extraction of fat or other matters from animal carcases, slaughter-house refuse and the like
IPC: C11B13/00
Filed: 1929-04-26
Abstract: 310,542. Sommermeyer, A. April 28, 1928, [Convention date]. Fats and fatty oils, extracting. - In a continuous process for digesting animal matters such as carcases, slaughterhouse refuse &c., with steam or solvent-vapour under pressure, the materials are fed through an orifice c into a perforated cylindrical or conical drum b, mounted in a chamber a, and rotated by a shaft g. The whole of the solid and liquid products pass through the perforations of the drum b continuously and is promptly separated into liquid and solid products by a fine mesh screening' or like surface d to avoid hydrolysis of the glueyielding constituents, such as occurs when the products pass to settling or decantation vessels subject to the working temperature and pressure. The liquid materials pass through an outlet f, and a worm w conveys the solid material to a discharge e. In a modification the screening surface d is formed by a perforated cylinder in a separate chamber. The liquid and solids are discharged from the outlet e into the cylinder, the solids being finally removed from within this cylinder by a worm conveyer. The residue may be pressed and worked up to yield glue.

Abstract: 1,194,832. Keysenders. GENERAL ELECTRIC & ENGLISH ELECTRIC CO'S. Ltd. 8 June, 1967 [24 March, 1966], No. 13054/66. Heading H4K. [Also in Division H1] In an electric push-button mechanism a carriage 20 is mounted on parallel motion links 22 and comprises parallel rods 21 each positioned below the stems of the buttons of one row, and each stem has an inclined surface which, as the button is initially depressed, engages the corresponding rod and displaces the carriage to a position in which the button can be further depressed without further displacement of the carriage giving the buttons a snap action. In the subscriber's telephone set shown, in the displaced position of the carriage the rods 21 are positioned to block depression of all buttons adjacent to the depressed button. The inclined surfaces are bevelled ends of the button stems, adjacent stems being bevelled in opposite directions. The middle rod 21 carries a sector-shaped cam which passes through a slot in one contact of a spring contact set 25 and engages another contact of this set. When the carriage is displaced the cam rotates operating the contacts. The contacts exert a centering force on the carriage and cause its return when the button is released. When a button is depressed a flattened side portion of the stem engages the rods 21 after the carriage has been initially displaced providing the snap action. The moulded plastics base 10 carries a printed circuit board attached at 16 and the push-buttons are arranged to operate contact-making members disposed between the base member 10 and the printed circuit board. The spring contact set may be replaced by a microswitch.

Abstract: 1,197,721. Method for producing uniform copolymers. IMPERIAL CHEMICAL INDUSTRIES Ltd. 26 June, 1967 [24 March, 1966], No. 13069/66. Headings C3G and C3P. [Also in Division B1] A method for producing uniform copolymers from two or more monomers having different reaction rates comprises feeding at least a portion of monomer having higher reaction rate to the reaction mixture at a rate dependent on the rate of production of heat in the copolymer formation. The method is suitably applied to a monomer mixture comprising (a) at least one vinyl monomer having an electron-withdrawing group, e.g. acrylonitrile, methacrylonitrile, α- acetoxy acrylonitrile, cinnamonitrile, chloroacrylonitrile, fumaronitrile, maleonitrile, maleic anhydride, vinyl methyl (or ethyl) ether or vinyl methyl sulphone and (b) at least one monomer selected from styrene, styrene derivatives, vinyl naphthalene, acenaphthylene, vinyl phenanthrene, indene, coumarone, vinyl pyridines, vinyl thiophene, vinyl carbazole, vinyl acetate, butadiene, isoprene, vinyl chloride, isobutene or methylpentene. It is particularly suited for monomer mixtures containing at least 50 mole per cent of acrylonitrile; such mixtures may be polymerized in the presence of a preformed polymer, e.g. a diene rubber, to form graft copolymers. In examples acrylonitrile is copolymerized with styrene or α-methylstyrene in aqueous emulsion using ammonium persulphate/sodium metabisulphite initiator in the presence of butane-thiol or octane-thiol; sodium dimethyldithiocarbamate is used to terminate (and also to control) the polymerization reaction. Also, in one example, acrylonitrile and styrene are graft copolymerized on to a butadieneacrylonitrile rubber in an aqueous medium using the same initiator and reaction-terminating agent as in the other examples. Special forms of apparatus for effecting the polymerization including means for measuring the heat produced in the reaction are described (see Division B1).
