Filed: 1940-07-31
Abstract: 540,993. Turning. BARLOW, R. R. C., and MAYER, J. C. July 31, 1940, No. 12418. [Class 83 (iii)] The turret 10 of a lathe which is fitted with two tool-holding recesses 11 is mounted on a handoperated slide 13 which when reciprocated imparts an oscillating motion to the turret so that the tools are moved alternately into and out of operative position at each actuation of the slide. The turret is normally locked in operative position by a bolt 16 raised to engage one of two bushes 14 by a spring-pressed lever 17 which is depressed by a lever 21 when the slide 13 is actuated to operate the turret. The rotation of the turret is effected by the engagement of pins 36, 37 with. pawls 22, 23 which are engaged by a spring-pressed rod 31 the ends of which are engaged in inclined slots 30 in blocks 26, 28 (not shown). When the slide 13 is withdrawn from the position shown the pin 36 engages the pawl 22 and rotates the turret counterclockwise, and the pawl 22 moves clockwise around its pivot and operates a rocking arm 35 which moves the pawl 23 to the dotted line position shown out of the path of the pin 37. Upon return of the slide 13 the pawls 22, 23 return to neutral position and the. locking bolt 16 comes into. action. On, the next withdrawal of the slide the pin 37 is acted upon by the pawl 23 to rotate the turret clockwise to its original position, and the pawl 22 is moved out of operative position.

Title: Polytetrafluoroethylene organosols
IPC: C09D127/18
Filed: 1951-06-01
Abstract: A fluid organosol comprises colloidal particles of polytetrafluoroethylene dispersed in an inert non-solvent liquid having a boiling point between 30 DEG  and 200 DEG  C. and having dissolved therein as a thickening agent a normally solid linear synthetic polymer which is thermally degradeable into volatile products and has a molecular weight of at least 10,000 as determined by the Staudinger method, such as polyisobutylene, isobutylene/styrene copolymers, isobutylene/diolefin copolymers, styrene/diolefin copolymers, acrylonitrile/diolefin copolymers, polychloroprene, polystyrene, polymethyl methacrylate, and polyvinyl acetate.  Suitable organic liquids are hexane, heptane, octane, nonane, decane, diisobutylenes, heptene, octene, cyclohexane, benzene, toluene, xylenes, mesitylene, ethyl benzene, hemimellitene, propyl benzene, terpenes, industrial naphtha, acetone, methyl isobutyl ketone, mesityl oxide, amyl acetate, n-butyl acetate, n-butyl lactate, ethers, and mixtures thereof. The organosols may be prepared (a) by mixing the organic liquid containing the dissolved thickening polymer with an aqueous suspension of colloidal polytetrafluoroethylene, which may contain a dispersing agent such as a polyethylene glycol ether of an alkylated phenol, followed by coagulation of the aqueous polymer suspension and separation from the aqueous phase; (b) by dispersing dried coagulated colloidal polytetrafluoroethylene in an organic liquid immiscible with the selected organic liquid containing the dissolved thickening polymer, and adding to the dispersion the thickened organic liquid which preferentially absorbs the polytetrafluoroethylene; (c) by spraying a mist of the organic liquid containing the thickening polymer on to dry particles of coagulated colloidal polytetrafluoroethylene which are being tumbled in a blender; or (d) by mixing a slurry of the dry coagulated colloidal polytetrafluoroethylene in the organic liquid containing the dissolved thickening polymer by means of a high-speed agitator.  The organosols may be used in coating and impregnating applications, and after the removal of solvent the residue may be heated at 250 DEG  to 500 DEG  C. to volatilize the thermally-degradeable polymer and sinter the particles of polytetrafluoro ethylene into a continuous film.

Abstract: 661,656. External drum brakes. ELLISTON, E. R. May 12, 1949 [May 12, 1948], No. 13064/48. Class 103 (i). In a spring- or weight-applied brake mechanism of the type in which the shoes 1 are moved to the brake released position by an electro-hydraulic power unit 5 comprising a double-acting piston, a cylinder and a centrifugal pump adapted to transfer liquid from one side of the piston to the other, a yieldable connection is interposed in the linkage between the power unit and the brake shoes whereby after the shoes having been applied to the brake drum, the linkage may be flexed from a rigid to a non- rigid condition against a reaction operative to apply full load to the power unit. In Fig. 1, in which the brake shoes 1 are normally applied by a spring 4, the yieldable connection takes the form of a pivot pin 13 connecting two linkage parts 11, 12, the displacement of which from the rigid position determined by the abutment pin 16 is resisted by spring 14. In another similar arrangement the spring 14 is arranged vertically in a similar manner to that shown for the spring 32 in Fig. 3 in which the brake shoes 1 are normally applied by a weight 30. In each arrangement the release position of the shoes 1 may be adjusted by the stop bolt 10.

Title: Improvements in foundry molding machines
IPC: B22C15/10
Filed: 1922-05-09
Abstract: 179,938. Lewis, W. May 13, 1921, [Convention date]. Moulding-machines. - Relates to roll-over moulding-machines and consists in improved means for rolling over the pattern plate M and for avoiding damage caused by stopping at the dead centre and then falling. The plate M, with a filled flask clamped thereto, is jarred by a device A, Fig. 1, separate from the turn over apparatus G but aligned therewith by a light plate g. The plate M is then lifted by arms N, L which are pivoted to a shaft I carried by two plungers H in cylinders G<1> containing liquid. The plungers are raised by the admission of compressed air at T<4>, T<5>, Fig. 2, by a valve T<1> and flexible pipe T<2>. A roller J<1>, Fig. 1, carried by links J from an arm I<3> rigid with the arms L, then engages a stop K<2> and the mould is rolled over. As this movement commences a lever O<1> is withdrawn from an adjustable fixed stop O<3> thereby allowing a spring N<9> to draw clamping jaws N<4>, N<7> into recesses M<1> of the plate M. During the rise of the plungers H choke blocks H<4> on fixed rods H<3> come within passages H<2> through which the liquid is passing and check the movement as when the roller J<l> is about to contact with the stop K<2>. When the plate has passed the highest point the air is released from the plungers and the roll over is completed, as shown in Fig. 8, but should the arms L stick at the dead centre a stop J<2>, Fig. 6, will engage a fixed abutment K<7> and arrest further movement. A table B<2> as described in Specification 10077/14 is then raised by oil, from a reservoir Q, Fig. 2, under air pressure through a valve P<5>, which is admitted to a cylinder B by a valve r' and then wedges C<1> are advanced, by operating a valve S<6>, to hold the flask firmly. The clamps are then released and the plate M again raised, by admitting air to the plungers H, to draw the pattern, vibrators U<6>, U<7>, Fig. 2, being started by operating a valve U'. For a deep draw the cylinder B may be simultaneously exhausted by the valve P<5> and a reducing valve P' to allow the table B<2> to fall on to a plunger F<1> set by a valve r<2> to receive it. During the lift the roller J<1> passes up a slot K<5> till it reaches an abutment K<3> and the plate M is rolled back, a pivoted stop J<3> operating to avoid danger of sticking at the dead centre. Liability to stick may be reduced by adjusting the eccentric pivot I<6>. The arms L are supported in their extreme positions by adjustable stops L<3>, L<4>, Fig. 8. H<5> is a shell connected to the plunger H and surrounding the upper end of its cylinder G<1>. h', Fig. 1, is a fixed diaphragm which prevents splashing of the fluid in the cylinder. If the links J are detached the machine may be used for lifting a cope flask from its pattern, through a stripping plate if desired. Specification 150,715 also is referred to.

[Class 135] A rotary plunger pump particularly adapted for energising a hydraulic motor for gun aiming purposes has the eccentric ring of the pump set in the desired position by a fluid-pressure servomotor in which the control valve co-operates with ports in the power device to give a followup action. In the form shown in the Figs. the casing is made in three parts 8, 9, 10 clamped together by tie-rods 11. A double-acting piston 1 works in a liner 18 in the part 9 and has tubular extensions 24 slidable in bushes in the end parts 8, 10. A member 3 secured to one of the extensions 24 by pins 25, 26 carries a transverse pin 27 engaging open slots 28 in a bifurcated crank 4 pinned to a shaft 2. The shaft 2 is connected to the cam ring of the pump by link mechanism or a Bowden cable or may carry a crank arm with a ball-shaped end engaging a slide attached to the cam ring. The piston has a pair of radial passages 41 leading to recesses 42 formed by flats on the piston periphery and leading through ports 40 in the liner to a semi-circular groove 38 in the casing connected to an inlet 36 for pressure fluid. Radial ports 44, 45 in the extensions lead to the chambers on each side of the piston. Inclined ports 48 in the piston lead to a recess 49 formed by a flat and connected by a port 50 in the liner with an exhaust connection 37. The control valve is slidably mounted in a bore in the piston and extensions and carries a transverse pin 31 engaging open slots 32 in a crank arm 7 pinned to a shaft 6. A control handle is directly or remotely coupled to this shaft. When the control valve is moved in one direction or the other pressure fluid is admitted through passages 41 and diametrically opposed grooves 43 to one side of the piston while fluid is exhausted from the other side through ports 45 diametrically opposed grooves 46 and passages 48. The chambers 21, 22 housing the crank arms 4, 7 are closed by detachable covers 13 and are connected to the exhaust outlet by alternative passages 51. The shaft 6 may be fitted with a friction damper comprising discs on the shaft interleaved with fixed discs. The Provisional Specification describes a modification in which a rotary vane motor replaces the reciprocating plunger.

Abstract: 652,769. Coating wires. SURPRENANT MFG. CO. May 14, 1948, No. 13257. Conven. tion date, Nov. 4, 1947. [Class 140] In a machine for helically striping elongated material such as wire, tubes, and cords, a feeddrum 44 is rotated to draw the wire W from a supply-drum 65 through a replaceable guide 96 in a synchronously-rotated hollow striping-unit 67 comprising a base 80 and a head 100 removable to enable wells 83, 84, 85 to be charged with striping liquid or ink, and a drying chamber 68, the striped wire then being guided by traversing pins 62 on to a reel 48. At the normal speed of operation centrifugal force causes the separate supplies of ink to rise to the outer ends of communication chambers C, formed by recesses 90, 91, 92 and as at 114, and be deposited on the peripheral surface of or in peripheral grooves on discs 130, 131, 132, which are in contact with the wire and rotated by movement thereof. The discs deposit the ink on the wire to form continuous stripes and also maintain the wire in central relationship to the striping unit. As the machine is permitted to come to rest gradually the inks, which may be of different colours, flow under gravity back to the wells without mixing or marring the wire. Each disc, Fig. 4, is mounted obliquely to the axis of the wire on a stem 126 angularly adjustable on a block 120, the position of which from the axis of rotation of the unit 67 may be varied to accommodate wire of different sizes.

Abstract: 1,118,083. Ski training and practising apparatus. G. D. MARVIN; M.. J. PROSSER and H. SCUDAMORE. 29 March, 1966 [30 March, 1965], No. 13391/65. Heading A6M. An apparatus for simulating water skiing conditions consists of an upwardly open water channel and pump means for maintaining a continuous flow of water thus providing a water surface on which a trainee is supported, for skiing practice or training. The apparatus preferably consists of two channels 13 and 14 (Figure 1) arranged so that a continuous flow of water is maintained uniformly over the whole width of the channels, the circulation being maintained by a pump 15 and motor 16. In order that the trainee may remain, in a constant position relative to the channel, the trainee should be supported in a suitable harness. A sluice gate 18 is provided upstream of both channels to maintain a proper depth of water in them. The channels may be inclined to the horizontal as in Figure 2 (not shown). Suitable means may be provided for producing waves on the water surface. Such means may consist of reciprocating members for disturbing the surface, cyclically varying the speed of the motor, using a suitable flow regulating device, or cyclically raising and lowering the sluices. Alternatively, a smooth flow of water may be obtained by fitting guide vanes 42 [Figure 5, not shown] to the channels. Tanks are fitted beneath the channels to store water when the apparatus is not in use.
