Title: Strap securing method
IPC: B29C65/14
Filed: 1965-01-19
Abstract: 1,071,042. Seaming non-metallic sheet material. FMC CORPORATION. Jan. 19, 1965 [Feb. 6, 1964], No. 2259/65. Heading B5K. Two portions 11, 12 of stretch oriented polymeric strap are secured together in overlapping face-to-face relationship by melting at least one of the portions 11, 12 in a zone including and immediately adjacent one of the faces thereof but without softening the extremity of the free end portion whilst maintaining the major part of the strap portion in stretch oriented condition, and pressing the melted zone of this strap portion against the other strap portion. As shown, a strap 10 has a free end portion 11 and a portion 12 which either extends to a supply or may be a free end. The portions 11, 12 are held apart, preferably by guide rollers, to abut against elements 13, 14 through channels in which cooling fluid is circulated. The opposed faces of the portions 11, 12 are heated by radiant heat from a thin heating blade 20 which is projected and retracted by a pneumatic cylinder 21 (not shown). When the blade 20 is in its retracted position the end thereof is located between a pair of heating devices 22, 23, Figs. 2 and 3 (both not shown). After softening of the opposed faces, the melted areas are squeezed together by moving the element 13 toward the element 14 or vice versa or moving both elements 13, 14 towards each other. Preferably the melted portion 24, Fig. 4 (not shown), does not extend to the end of the strap. The cooled elements 13, 14 prevent heat from migrating through the strap whilst the pressure thereof is maintained. The strap may contact the heating blade but preferably such direct contact is avoided. The blade 20 may be heated electrically and may be replaced by an element of substantial thickness. Specified polymeric materials are polyolefines, e.g. polypropylene, polyesters, polyamides and acrylic resins. A polypropylene strap, of 0À5 mm. thickness, which softens at about 107 C. and melts at about 155 C., is heated at about 1À5 mm. from an element at 593-650 C. for a few milliseconds so that the inner faces of the strap are melted to a depth of 0À08-0À10 mm. and softened for an additional 0À05-0À08 mm.

Title: An improved protective circuit arrangement for installations comprising a remotely controlled automatic electric switch
IPC: H02H7/00
Filed: 1935-01-24
Abstract: 428,357. Protective cut-out arrangements. SHEVLIN, J. T., 15, South Street, Finsbury, London.-(Siemens-Schuckertwerke Akt.-Ges.; Siemensstadt, Berlin) Jan. 24, 1935, No. 2425. [Class 38 (v)] In a protective arrangement for installations comprising an automatic circuit-breaker 8 operatively associated with an earth leakage relay 13 and controllable from a remote control position over a cable 5 containing a control line 17 and earth line 18, more particularly for controlling the motor 6 of a coal-cutting machine, an earth relay coil 22 provided at the control position is responsive to a short-circuit between the control line and earth line, and on such response establishes an earth circuit through a limiting resistance 24 from one of the supply lines of the installation, and thereby operates the earth leakage relay 13 to open the circuit-breaker 8. In the arrangement shown, the relay 22 is directly connected in the control line 17 which also includes the contacts of the relay 13, a no-volt coil 11 and the secondary winding of a transformer 9 energized from the supply. If the main switch 7 is closed, closure of a button 25 energizes a starting relay 12 connected in parallel with the no-volt coil 11. The relay 12 in turn closes the circuit of the operating winding 10 of the circuitbreaker 8 ; the latter thereupon closes and is held closed by a latch as long as the no-volt coil 11 is energized. The winding of the earth leakage relay 13 is connected to an artificial neutral point formed by three resistances or capacities 14, 15, 16 connected in star to the motor supply conductors, the arrangement being such that if the relay is energized the connection between the control line and the no-volt coil 11 is interrupted and the circuitbreaker 8 is released. In the event of a short circuit between the control line 17 and earth line 18, the coil 22 is de-energized, and one of the supply conductors is connected to earth through the resistance 24. The resulting displacement of the neutral point causes the earth leakage relay to respond, with consequent opening of the circuit-breaker 8. The latter may be opened at any time by depressing a button 26 to interrupt the circuit through the control line 17.

[Classes 30 and 131.] In a safety razor wherein the blade 6 is transversely flexed between a cover-plate 5 and a supporting member, and its edges are protected by a fixed guard, a trough is provided below the supporting member to receive detached hairs and lather. As shown in Fig. 10, the trough 1 carrying the comb teeth is attached to the handle 2 by a connecting piece 7. A space for the passage of lather is provided between the supporting plate 9 and the trough 1 such as by recessing the longitudinal edges 9a, Fig. 5, of the plate, or by making the plate narrower than the blade, in which latter case it is supported on bridge-pieces at each corner of, or extending transversely across the narrow edges of the trough 1. The bridge-pieces may be used without the supporting plate. The plate 9, which may have one of its narrow edges formed as a comb 19 for the beard or moustache, may have a rectangular opening 9b or may be simply apertured for the passage of the usual clamping and aligning pins. In the form shown in Fig. 12, the supporting plate has downwardly bent arms 17 which carry the comb teeth, and the trough is formed by a dish 13, which may be trapezoidal with closed ends or semi-elliptical so as to embrace the arms 17. In a further form the trough, supporting plate and guard are formed by a single elliptical member which has a flattened or arched top part on which the blade rests and which is cut away along each side to form the comb teeth. The narrow sides of the blade may be undulated to facilitate handling, and the trough, supporting and clamping plates may be of metal or of a material such as celluloid or paper intended for use once only. The Specification as open to inspection under Sect. 91 (3) (a) states also that the contents of the trough may be automatically removed by suction means or by rotating wires. To facilitate suction withdrawal the trough may be divided by longitudinal or transverse partitions, and the trough is emptied through the hollow handle which is connected to a flexible rubber or metal tube. The supporting plate 17, Fig. 12, may be oval, trapezoidal or elliptical. This subject-matter does not appear in the Specification as accepted.
