Title: Excess current switch
IPC: H01H71/24
Filed: 1972-06-05
Abstract: 1364990 Excess current switches ELLENBERGER & POENSGEN GmbH 5 June 1972 [1 July 1971] 26170/72 Heading H1N In order to manually close an excess current switch (Fig. 2), so that contact arcing on closure is reduced, a stop 50 is engaged by the latch portion 26 just before the contacts make, such that further movement of the actuating lever 1 stresses the spring 31, the latched member 25 then being tripped by the portion 30 on the arm 5 of the lever 1 allowing the contacts to "make" rapidly. For automatic opening, the lever 41 trips the locking member 16, allowing the two portions 9, 13 of the toggle arrangement to collapse, and the contacts are separated under the action of spring 28, Fig. 3 (not shown). Thermal 39 and/or electromagnetic 37 tripping means may be used. In case of short circuit currents, the electromagnetic means also assists the contact separation, the projection 46 on the armature actuating the bell crank lever 49 which strikes the base of the contact arm 24. A further projection in the housing (not shown) may engage an additional arm on the locking member during manual opening of the switch to collapse the toggle. Alternatively manual opening may be achieved with the toggle locked, (Fig. 2). The spring 6 causes the collapsed toggle to be relocked after a trip type release, setting the actuating member from the open position to the switch tripped position.

Title: Improvements in and relating to heating of metal cylinder adapted for goffering or embossing films
IPC: G03B21/32
Filed: 1932-09-27
Abstract: 395,200. Thermal switches. KELLERDORIAN COLORFILM CORPORATION, 522, 5th Avenue, New York, U.S.A. Sept. 27, 1932, No. 26855. Convention date, Oct. 9, 1931. [Class 38 (v).] A metal cylinder adapted for embossing'or goffering films, as distinct from an internallyheated cylinder, is provided with means for applying heat at its surface ; the heating means is located at the periphery of the cylinder and is adapted to function while the cylinder is in operation. The goffering-cylinder 45, which may be provided with semi-cylindrical longitudinal ridges, may be heated to any desired temperature by eddy currents produced by mounting the cylinder in the field of an electromagnet 75, a thermostatic control 77 being provided adjacent the periphery of the cylinders. The thermostatic control may comprise a silver tube 78, Fig. 4, mounted at one end in a supporting frame 79, while the other end is internally connected to a quartz rod 81, the free end 82 of which is in contact with a pivoted arm 83 attached to the frame 79. A strong spring 85 presses the arm 83 against the end 82 so that its bevelled end 87 engages the bevelled end 88 of an arm 89 pivotally mounted on a bracket 90, and a weak spring 91 normally presses the arm 89 against a thumb-screw 92, whereby a circuit is completed between contact 92 and the arm 89 to energize an electromagnet 95. The latter then attracts its armature 99 to complete the circuit of the energizing coils of the electromagnet 75, so that when the cylinder and consequently the thermo-couple become overheated, the expansion of the tube 78 permits the spring 85 to overcome the spring 91 and break the contacts 92 and 89. A modified heating-device is shown in Fig. 5 and comprises a heating-coil 113 which is controlled by a mercury column 129. As the temperature of the cylinder increases, the mercury column 129 rises until it touches an adjustable contact screw 135 and completes the circuit of an electromagnet 140, which attracts its armature 121 and thereby breaks the circuit of the heating-coil 113.

[Also in Division D1] An automatic continuous roll-winding device comprises a horizontal cylinder 1 which can be rotated in either direction, and which carries bearings 2 on its circumference in which are mounted, at 2a and 2b, spindles 7. The spindles 7 receive the material 5 to be wound up and are driven by a wheel (17) mounted coaxially with the axle of the cylinder 1 via a friction coupling with a wheel (16) fixed to the spindle. A feed magazine 3 loads the bearings 2 with spindles as the cylinder rotates. A discharge magazine 10 with pick-up edge 11 unloads the wound spindles from bearing 2b as the cylinder rotates. A cutter 8 cuts the material wound on the spindle. One cut end of the tape is secured to the fully wound spindle, the other is secured to the succeeding empty spindle. A lever (12) on the cutter may press and secure the free end of material against the spindle in bearing 2a. The control mechanism used with device may be driven mechanically, pneumatically, hydraulically or electromechanically. The control mechanism operates when a predetermined length of material has been wound. The bearings 2 can be as open slots, preferably curved as shown. The drive wheel (16) can be driven by a further gear (19) acting on a flange (18) of drive wheel (17) (see Fig. 3, not shown). The material being wound can be printed or unprinted tapes of paper, plastic, cloth, metal or threads, yarns or ropes, particularly pressuresensitive polyvinylchloride tape. This latter tape sticks to the spindle in bearing 2a at the start of the winding and the free end of this wound tape on the spindle is coated with a silicone. If the tape is not sticky the spindles can be coated with a pressure-sensitive adhesive and the end of the wound tape glued by the coating device 9.
