Title: Method and apparatus for inertial spinwelding of thermoplastic container ends
Inventor: FORTUNA VINCENT
IPC: B65D8/22
Filed: 1985-10-31
Abstract: A thermoplastic end is inertially spinwelded onto the paperboard sidewall of a container body, the end having an annular grove for snugly receiving the sidewall and a wall configuration which minimizes the forces exerted on the bond by liquid contents which would tend to dislodge the end portion. The end portion has strengthening ribs positioned generally within the region of U-shape and additional radial ribs imparting strength and rigidity to the container end. The paperboard sidewall may be internally lined with a layer of thermoplastic material or may be unlined. During spinwelding, a sidewall supporting mandrel 28 having an expandable engaging portion is inserted into the sidewall and subsequently expanded to define a cylindrical surface of a diameter equal to that of the specified internal diameter of the sidewall. A seating member at the end of the sidewall supporting mandrel establishes the depth to which the container end is inserted into the sidewall and is provided with a low-friction member which contacts and aligns the rotating container end with the container sidewall; Figs 4-9 and 13 (not shown). <IMAGE>

Title: Determining gun muzzle displacement
Inventor: HODGES PETER
IPC: F41G3/32
Filed: 1985-11-22
Abstract: An arrangement for quantitatively determining muzzle displacements such as bending of a long elevatable gun barrel 11 comprises an electronic CCD camera 25 pivotally mounted at 26, coupled to a sight 15, pivoted at 20, by a linkage rod (27) so that the camera field of view receives an image of a muzzle portion of the barrel as it moves in elevation with the sight. To avoid gun follow elevation error, that is, a change in muzzle image position with respect to the camera field of view as the sight is rotated through its elevation range the disposition of pivot points 20 and 26 length of rod (27) and distances from pivot points 20 and 26, at which the rod is connected, form a quadrilateral linkage whereby rotation of the camera in elevation differs from rotation of the sight by the proportion of the gun follow elevation error for that elevation angle. This enables the muzzle portion which carries a straight edged marker 33 of known dimensions to fill a larger part of the image and for signal processing means (45) to determine, in a calibration mode, a datum image position and the number of resolvable image pixels occupied by the marker to give a resolution factor. Subsequently during gun firing displacement of the muzzle image is multiplied by the resolution factor to determine quantitatively the value of muzzle displacement. A smaller gun follow azimuth error, causing azimuth movement of the image in the camera, is corrected for by the processing means or may also be corrected by appropriate coupling between camera and sight. <IMAGE>

Title: Dual voltage electric heating apparatus
Inventor: TAKESHITA SEISUKE
IPC: A45D20/30
Filed: 1986-10-02
Abstract: The apparatus, particularly a hair dryer, has switching means 28, 40 which operate automatically to connect heating elements 8, 9 in parallel when the supply voltage is below a predetermined level and in series when the voltage is above that level. With a voltage of 100 to 120V, bias 40 is turned on and changeover switch 28 is at contact 28a to effect the parallel connection, whenever with a voltage of 200 to 240V bias 40 is turned off and relay coil 27 is energised to change switch 28 to contact 28b to effect the series connection. An alternative embodiment uses two relays to effect the switching, the relays being operated sequentially to avoid short circuiting the supply. (Figures 6, 7, 9). One or more protection resistors (44), (Figure 8), (83), (Figure 9), (95), (96), (Figure 10), may be connected in series with various switch contacts to limit any short circuit current that may flow in the event of arcing between switch contacts-such as 28a, 28b- caused by vibration of movable contact plastic when the apparatus is subjected to physical shock. The protection resistors may contribute to the heating effect. A further switch (67), (Figure 6), may be provided having a "low" heat position in which the heaters are energised via a diode (72) in parallel with a resistor (73), and a "high" heat position in which this diode and resistor are shorted. <IMAGE>

Patent GB-2208338-A (GB)
Title: Earth connection and seal
Inventor: HAMBLIN BRIAN DAVID
IPC: H01R13/52
Filed: 1988-07-22
Abstract: An earth connection and seal for a cable received in an enclosure of electrically non-conductive material. A cable entry (22) passes through an aperture in a wall of a plastic junction box (24) and then through an adjacent seal (18) and a conductive plate (10) adjacent to said seal (18). Said seal (18) and conductive plate (10) may be bonded together. The aperture of the seal (18) is such as to provide a force fit with the cable entry (22) and therefore prevents movement of the conductive plate (10) which supplies an earth connection to the junction box via a tag (14). Tightening of plate (10) on cable entry (22) compresses the seal onto the cable entry. Projections (26) prevent excessive compression of the seal (18) between the junction box (24) and the conductive plate (10). <IMAGE>

Patent GB-2216636-A (GB)
Title: Fluid friction clutch
Inventor: IHLEMANN ARNDT
IPC: F16D35/02
Filed: 1989-03-23
Abstract: A fluid friction clutch has two parts (7b, 21b) rotatable in relation to one another about a common axis (1b), which define a shear gap (23b) of zig-zag or serpentine form between them. The shear gap (23b) is limited by ribs (59, 61) coaxial with the rotation axis (1b), which interengage in alternation. The individual ribs (59, 61) have side flanks (63, 65 and 67, 69) inclined towards one another, the generatrices of which are inclined at mutually differing angles to the rotation axis (1b). The mutually relatively rotatable parts (7b, 21b) of the clutch have different radial thermal expansions, so that the shear gap sections (75, 77) of different inclination to the rotation axis (1b), determined by the side flanks of the ribs (59, 61), narrow or widen by difierent amounts on a temperature variation. The different inclinations of the shear gap sections (75, 77) determine the course of the output rotation rate - input rotation rate characteristic of the fluid friction clutch in the range of higher input rotation rates. <IMAGE>

Title: Graft copolymers and blends thereof with polyolefins
Inventor: ILENDA CASMIR STANISLAUS
IPC: C08L25/04
Filed: 1989-03-28
Abstract: A novel graft copolymer capable of imparting to a polyolefin when blended therewith a good balance of tensile modulus, sag resistance and melt viscosity, is a polyolefin trunk having a, preferably relatively high weight-average molecular weight, methacrylate polymer chain grafted thereto. The graft copolymer is formed by dissolving a non-polar polyolefin in an inert hydrocarbon solvent, and, while stirring the mixture, adding methacrylate monomer together with initiator to produce a constant, low concentration of radicals, and covalently graft a polymer chain, preferably of relatively high molecular weight, to the polyolefin backbone. The graft copolymer can be separated from the solvent, by volatilizing the solvent, for example in a devolatilizing extruder, and pelletised or extruded or otherwise shaped into a desired shape such as a sheet, tube or the like. This graft copolymer can be blended with a polyolefin matrix to improve its physical properties in the melt, upon cooling, and in the solid state, and is useful in cast and oriented films, solid extruded rod and profile, foamed rod, profile and sheet and blown bottles. The graft copolymer can also be used to improve compatibility between polymers in a wide range of polymer blends.
