Title: Improved process and apparatus for the melt-spinning of synthetic linear polymers
IPC: B29C48/92
Filed: 1964-09-24
Abstract: 1,040,499. Melt spinning apparatus. SVIA VISCOSA SOC. NAZIONALE INDUSTRIA APPLICAZIONI VISCOSA S.p.A. Sept. 24, 1964 [Sept. 30, 1963], No. 38953/64. Heading B5B. A melt-spinning apparatus comprises a melting chamber 10 (Fig. 1, not shown), a heated melting grid 12, a feed screw 13 mounted in a shaft 14, a tube 18 for the introduction of solid particulate polymer and a conical sump 11 provided with an outlet for holding a pool of melt. The shaft is rotatably supported in bearings 20, 21 and 23 and has mounted on it toothed wheels 24 and 24<SP>1</SP> (Figs. 1 and 2, not shown), meshing with racks 25 and 25<SP>1</SP> carried on rods 26 and 26<SP>1</SP> connected to the piston 27 working in a cylinder 28. Compressed air in other fluid is introduced into and discharged from cylinder 28 through valves 29 and 29<SP>1</SP>, the fluid being introduced into the cylinder at a pressure which is in accordance with the pressure it is desired to apply to the mass of particulate polymer 30 above the melting grid 12 of the melter 10. As illustrated in Fig. 1 (not shown), compressed air is introduced into the cylinder 28 through the valve 29, while valve 29<SP>1</SP> is open to the atmosphere. If the pressure exerted on the mass of polymer 30 by the screw 13 has not reached a predetermined value, the piston 27 is urged to the right and the toothed wheels 24, 24<SP>1</SP> are rotated in a counter-clockwise and a clockwise direction by the racks 25, 25<SP>1</SP>. Each of the wheels 24, 24<SP>1</SP> mounted on the shaft 14 with a freewheel device in such a manner that the shaft is always rotated in the same direction (the direction being such that the screw 13 causes the polymer to travel downwards towards the melting grid 12) irrespective of whether the piston 27 travels from left to right or vice versa. During the phase shown in Fig. 1, the wheel 24<SP>1</SP> causes the shaft 14 to rotate in a clockwise direction while the wheel 24 freewheels on the shaft. The torque applied to the shaft 14 is constant after the pressure applied to the mass of polymer 30 has reached the predetermined value and the pressure exerted in the polymer by the screw 13 thereafter remains constant. Instead of the driving means illustrated in Figs. 1 and 2, the shaft may be driven by means of a constant torque engine or electric motor.

Title: Method of winding armatures
IPC: H02K15/09
Filed: 1972-08-25
Abstract: 1371558 Securing windings to commutators GLOBE TOOL & ENG CO 25 Aug 1972 [3 Sept 1971] 39737/72 Heading B3A A method of winding an armature 10 com prises holding one end of a coil winding wire W in fixed relation to an armature to be wound and, while holding the wire, forming a first wire loop (L 1 ), Fig. 6 (not shown), about a preselected. commutator hook 22 by hooking the wire about the hook 22, continuing the wire around the hook, again hooking the wire about the hook while holding the end in fixed relation to the armature, and then releasing the fixed end of the wire adjacent the hook. A commutator 18 is mounted upon a shaft 16 of the armature core 12 and has a plurality of segments 20 terminating in the hooks 22. An insulating sleeve 23 covers the shaft section from the core to the commutator. The armature is supported between winding forms 24, 26 each rotatably receiving respective flier spindles 32, 40 on which are mounted fliers 34, 42 which rotate in opposite directions. Appropriate machine controls (not shown) are provided for parting forms 24, 26 to insert or remove an armature, to rotate fliers 34, 42 in timed sequence, and to index and rotate armature 10. The hooks 22 are shielded by shield 48 and movable sleeve 52 during coil winding. At the start of the winding sleeve 52 is retracted to expose a pair of horizontallylocated hooks 22. A wire clamp 54, which comprises a pair of jaws, is used to clamp the wire W prior to the forming of loop (L 1 ) during which the flier 34 is rotated in its forward direction, Fig. 2 (not shown), sleeve 52 is retracted from core 12 to expose a hook 22, then the flier is reversely rotated followed by replacing of the sleeve 52 and forwardly rotating the flier to position (34<SP>1</SP>). A second loop (L 2 ), Fig. 7 (not shown) may be formed when winding relatively fine wire by first retracting sleeve 52, rotating flier 34 reversely, Fig. 3 (not shown), replacing the sleeve, and rotating the flier 34 in the forward direction, Fig. 5 (not shown), to return it to position (34<SP>1</SP>). The wire can then be severed between clamp 54 and hook 22 using a cutter blade (55) and the flier 34 can be rotated in the forward direction to wind the first coil. Pivotally mounted guide members 58, 60 are used to positively guide the wire W about hooks 22 and comprise notches (66), Fig. 4 (not shown), to receive the hooks and wire guide surface portions (68), 70 to guide the wires when the fliers 34, 42 are reversely rotated. Vertically movable drive members 76, 78 engage and actuate drive members (not shown) to pivot members 58, 60 about pins 62, 64.

Title: Hydraulic locking devices
IPC: F16B1/00
Filed: 1964-10-01
Abstract: 1,017,328. Hydraulic locking devices. P. L. PORTER, C. B. PORTER, L. C. PORTER, and S. P. LENNOX, [trading as P. L. PORTER & ASSOCIATES]. Oct. 1, 1964, No. 40039/64. Heading B8J.  An hydraulic locking device for releasably locking two members at selected spacing (which may be used to control a tiltable aircraft chair back rest), comprises a single cylinder 10 with an ear 12 having an aperture 14 to connect to one of said members and a structure including an outer cylinder 15 and an inner cylinder 16 fixed thereto and an end fitting 18 to be connected to the second said member. The inner cylinder 16 slidingly telescopes into the single cylinder 10 with a sealing ring 22. A first hydraulic chamber 35 and a second hydraulic chamber formed by coaxial annular compartments 36 and 38, which are interconnected by a plurality of radial bores 40 in the single cylinder 10, are normally prevented from communicating by a locking valve 44. Slight clockwise movement of a control lever 70 operates through rods 74, 75, Fig. 2 (not shown), to unseat a ball 54 to put the two hydraulic chambers into communication so that the overall length of the device may be altered, when release of the control lever re-locks the device. Hydraulic fluid in a reservoir 80 under pressure from a spring 86 is placed into communication with the two hydraulic chambers, to replenish lost fluid, whenever the control lever 70 is moved sufficiently to open a check valve comprising an 0-ring 88 and a shoulder 90 on the rod 75. A heavy coil spring 95 acts as a counterbalance to resist contraction of the device. An over-riding mechanical force applied to extend the device cause ball valve 54 to open against a spring 60 through rise of pressure in the annular compartments 36, 38.

Patent GB-989249-A (GB)
Title: Lubricated polymers and their production
IPC: C08K5/07
Filed: 1962-10-23
Abstract: Polymers are internally lubricated by incorporation of 0.01-1% of one or more fatty ketones of formula CH3-(CH2)n-CO-(CH2)n-CH3 where n is 10-18, during or after polymerization of an aromatic vinyl monomer or a copolymer of such a monomer with one or more vinyl monomers, or a mixture of such polymers with or without one or more elastomeric resins. The ketone may be laurone or stearone and may be incorporated in the polymer by mechanical mixing in the cold or hot, or by melting the ketone in the monomer.  In examples styrene, with and without acrylonitrile, was polymerized with the ketone in suspension in water using calcium phosphate as suspending agent, polyvinyl alcohol as protective colloid and benzoyl peroxide as catalyst; styrene was polymerized in bulk with the ketone and polymerized as an emulsion in water using stearic acid and potassium hydroxide, dodecyl mercaptan and potassium persulphate and the emulsion was coagulated by heat treatment; and a mixture of styrene polymer and butadiene-styrene (3:1) copolymer containing ketone was granulated.

Title: Hydraulic well pump
IPC: F04B47/08
Filed: 1957-12-30
Abstract: 831,394. Reciprocating pumps. SARGENT, E. J. Dec. 30, 1957, No. 40313/57. Class 102(1). [Also in Group XXIX] An hydraulic motor for operating a deep well pump comprises a cylinder 26 housing a piston assembly 34 having a valve block 66 fast therewith, a delivery tube 46 being secured to the valve block and passing through the piston assembly and opening into a liquid supply conduit 15 to which the cylinder is secured. A tube 16 through which exhaust liquid passes is secured to the valve block and is connected to operate a plunger 17 of a well pump 13. A chamber 64 above the piston assembly is permanently open to exhaust via a clearance 69 between the piston assembly and a sleeve 30 fast with the cylinder, a space 67 between the piston and the valve block, bores 84 and 89 in the valve block and tube 16 and a port 23, where it mixes with the pumped fluid supplied through a port 21, and passes through ports 22 into tubing 12 to the surface. As shown in Fig. 4 the piston is making a downward stroke, and a main valve 73 is in its uppermost position in which a chamber 65 beneath the piston is open to exhaust via a passage (not shown) leading to a port 80, around the valve stem and through a port 83 to the bore 84. The piston is moved downwards by liquid pressure acting on the top of the tube 46. At the end of the stroke a ring 114 engages a collar 29 in the cylinder and moves a pilot valve 92 upwards relative to the valve block. A chamber beneath the main valve is thus opened to exhaust and the valve moved to its lowermost position in which the port 80 is open to tube 46 so that pressure liquid is supplied to chamber 65 to raise the piston. At the top of the stroke a ring 109 engages the end of sleeve 30 and the pilot valve is moved downwardly to direct pressure beneath the main valve to raise it and initiate another downward stroke. The piston is cushioned at the ends of its stroke, towards the lower end a cap 49 on the delivery tube 46 enters a bore 117 to restrict escape of liquid trapped therein. Towards the end of the return stroke clearance 69 is restricted by means of a portion 43 of the plunger co-operating with a tapered surface at the end of sleeve 30. Short stroking sometimes occurs at the upper end of the pump stroke due to withdrawing fluid faster than the rate at which it flows into the well or due to a large proportion of gas in the oil, so that there is a shortage of liquid beneath the pump plunger. The motor piston assembly is driven downwards very rapidly due to the weight of liquid within the tubing 12, and liquid cannot escape sufficiently rapidly from the chamber 65 so that a back pressure develops which prematurely reverses the pilot valve. This difficulty can be overcome by providing check valves in the ports 22. The pump may tend to stop or hesitate at the lower end of the stroke due to failure of the pilot valve to remain in its uppermost position, this can be overcome by a modified form of pilot valve and porting arrangement Fig. 12 (not shown).
