Title: Hydraulic device with rotor seal
IPC: F04C2/10
Filed: 1975-03-05
Abstract: 1481911 Rotary positive-displacement fluid-machines TRW Inc 5 March 1975 [22 March 1974]  9203/75 Heading F1F In a gerotor-type hydraulic motor, or pump, leakage from the spaces between the stator 21 and rotor 22 to outlet, or inlet, bores 52, 53 in a power output, or input, shaft 15 is minimized by provision of an annular seal 100 in a side face 104 of the rotor. As shown in Fig. 2 the seal gives fluid in the said spaces access to the face 104 so that the rotor is pressed against a non-rotating plate 49. Another non-rotating plate 44, upon which the seal bears, may contain passages 56 extending between the said spaces and a flowcontrolling valve-plate 47, which is rotated in a planetary manner by a "wobble shaft" 33 interconnecting the rotor and shaft 15. Low-pressure working-fluid flows from, or to, the plate 47 by way of bores 50, 51, the high-pressure working- fluid being supplied, or discharged, through an annular passageway 26 beneath a cylindrical casing 12. To reduce wear the seal may be made of polyethylene having a molecular weight of 2.8 x 10<SP>6</SP>. Alternatively, an annular seal 236 is lodged in the inner one of two plates 212, 214 in place of the plate 49, an annular groove 224 in the inner plate being connected to the annular passageway 26a by a radial passage 228. The pressure transmitted to the outer side-face of the plate 214 from the passageway 26a forces the plates apart and the rotor against the plate 44a.

Title: Improvements in and relating to apparatus for electric arc stud welding
IPC: B23K9/20
Filed: 1949-04-06
Abstract: 680,531. Welding by pressure. CYC-ARC, Ltd., AINSWORTH, A. -R., and MILLER, J. B. March 17, 1950 [April 6, 1949; Jan. 9, 1950], Nos. 9379/49 and 533/50. Class 83 (iv). In stud welding apparatus comprising a body and a stud chuck carrier having a wide range of movement relative to the body, the carrier consists of at least two parts coupled together to permit relative movement thereof equal to the arc length and such that the parts always take up a position in which the relative movement is possible, and electromagnetically operated means for effecting the frictional engagement and retention of the carrier in any position to which it is moved by the butting of a stud upon a plate. In an embodiment, a gun comprises a casing 1 surrounding a solenoid coil 4 and a clutch operating coil 8. A member 17 forms the core of the solenoid 4 and is secured to a magnetic clutch member 18 by a screw 31 in the end of the core 17 which screw passes with clearance through a hole in the end of the member 18. A collar 33 on the end of the screw 31 is acted upon by a spring 29 which urges the members 17, 18 apart. The member 18 slides within a liner 5, in which is mounted a spring 13, a conical ring 15 and abutment ring 23, and slides within an armature 24 which when a polepiece 25 thereon is attracted by a polepiece 10, moves forward to press steel balls 27 arranged about the member 18 into contact with the member 18 and the ring 15 to frictionally retain the member 18. A helical return spring 21 is mounted between the coil 4 and a damping piston 19. A casing 46 carries pins 50 on an interrupted ring 49 which resiliently supports a ferrule 52. In operation a stud is placed against the work and the gun is pressed until the pins 50 engage the work, during which time the core 17 and member 18 have moved into the casing 1 against the spring 21. A switch 44 is pressed to start the welding current and simultaneously energize the coils 4, 8. The pieces 10, 25 move together and the armature 24 effects locking of the member 18. The core 17 moves against the spring 29 until the member 18 is engaged, thus withdrawing the stud and striking an arc. De-energization of the coils 4, 8 allows the spring 21 to butt the stud into the work. The core ring 15 may be replaced by wedges &c. A further piston at the rear end of the member 18 may be used. In a modification, an externally roughened clutch member is retained by magnetic attraction between it and the internally roughened walls of a solenoid former, one coil being used for solenoid and clutch purposes. Two separate coils may be used in this modification and a single coil may be employed in the first embodiment.

Title: Stretching cast elongate bodies of thermoplastic synthetic resins
IPC: B29C61/02
Filed: 1943-06-18
Abstract: Cast elongate bodies, e.g. rods or tubes, of polyacrylic or methacrylic esters, e.g. polymethyl methacrylate, are drawn by heating the body to its softening point, stretching it in the direction of its major axis by application of tension at both ends and cooling while maintaining the tension.  Heating may be effected by immersion in hot water or mineral oil or exposure to heated air. Cooling may be effected by plunging the body into a bath of oil or water or allowing it to cool in air.  Stretching may be effected in the heated bath or after removal therefrom. After stretching it may be annealed by allowing it to remain in the bath for a few minutes. Sections may be cut from the stretched bodies and shrunk by heating them to the softening point while permitting contraction.  Spheres become ellipsoidal when so treated, and may be used as buttons.  The polymer may have light-reflecting lamell  distributed through it and oriented concentrically with respect to its major axis as described in U.S.A.  Specification 2,168,331.  It may contain also plasticizers, fillers and dyes.  The invention may be applied to interpolymers of the esters with each other or other polymerizable compounds.
