Title: Cartridge opening device
IPC: G03D13/00
Filed: 1972-09-08
Abstract: 1401016 Breaking open film cartridges EASTMAN KODAK CO 8 Sept 1972 [9 Sept 1971]  41868/72 Heading G2X A device for breaking open film cartridges 1 has means for supporting the take-up chamber 7 so as to prevent movement in at least one direction, and also for forcing the remainder of the cartridge in the same direction so that it fractures. As shown, the device is mounted on a vertical plate 13. A plate 17 carrying a tapered spindle 24 is secured to plate 13 by pins 18, 19, 20 but spaced therefrom by spacers 21, 22, 23. Spindle 24 fits into a similarly-shaped recess 25 in the take-up chamber 7, see also Fig. 2 (not shown), rotation of chamber 7 on the spool being limited by stops 27, 28. A guide arm 15 can pivot on a pin 31 secured to plate 17, and is urged anticlockwise by a spring 32 against a stop 36 on plate 17. In loading a cartridge into the device, the take-up chamber 7 is slid along a guide surface 33 extending from arm 15 until it seats on spindle 24, and is retained there by an offset portion 40 of guide 33. Such loading can conveniently be carried out under darkroom conditions. A breaker lever 16 having a handle 44 is also pivoted on pin 31, and is urged in a clockwise direction by a spring 41, the spring having arms 42, 43 abutted respectively against the under-side of handle 44 and a backstop wall 45 of plate 17. Lever 16 includes an offset portion 46 and a bumper 47, and in the rest position bumper 47 abuts against backstop wall 45, When the cartridge is mounted on the device, handle 44 and hence lever 16 is pivoted anti-clockwise, so that a blade 49 and jaw 50 come into contact respectively with the central part 8 and the supply chamber 5 of the cartridge. The whole cartridge is thus pivoted anti-clockwise on spindle 24 until a shoulder extension 29 on chamber 7 abuts against stop 27, so that chamber 7 can rotate no further. If rotation of lever 16 is still continued further, then the cartridge is fractured, and parts 8 and 5 broken away from chamber 7, so that the film can now be extracted (Fig. 6). A shield 53 protects the operator against any flying fragments.

Title: A safety device for high frequency alternator plants
Inventor: VIART FERNAND

Abstract: 1,023,906. Protective systems; supply systems for induction heating. ATELIERS DE CONSTRUCTIONS ELECTRIQUES DE CHARLEROI (ACEC). Oct. 14, 1964 [Oct. 15, 1963], No. 41977/64. Headings H2H and H2K. A protective arrangement for a system, e.g. an induction heating system, having high-frequency alternators A 1 , A 2  connected in parallel to bus-bars B and a plurality of output lines, as X, comprises a contactor D 1'  D 2  or Dx for each of the input and output lines, each contactor having a coil normally energized by a first voltage source Rd 1  or Rd 4  through a unidirectionally conducting device d 1 , d 2  or dx. A current transformer Ti 1 , Ti 2  or Tix in each line is connected to an electronic overload relay R 1 , R 2  or Rx which normally maintains a time delay relay F 1 , F 2  or Fx energized (with its contacts closed) and blocks a switching device, e.g. thyratron, T 1'  T 2  or Tx. Should an overload occur, e.g. air line X, the relay Rx operates to de-energize the time delay relay Fx and to unblock the device Tx. Current now flows from a second higher voltage source Rd 3  through an impedance Z, the device Tx and contacts fx 1  of the delay relay Fx to maintain the coil Dx energized. The resulting voltage drop across the impedance Z blocks the rectifiers of the sources Rd 1  and Rd 2  so that the coils of contactors D 1 , D 2  are deenergized and the field windings of the alternators A 1 , A 2  cease to be excited. This causes the removal of the overload current so that when the delay relay Fx opens its contacts fx 1  and fx 2  the contactor Dx opens without excessive arcing. The opening of these contacts interrupts the supply from source Rd 3  through the impedance Z, so that the sources Rd 1  and Rd 2  again supply the contactors D 1 , D 2  and the alternator field windings, the system reverting to normal except that the line X remains disconnected as the relay Fx is not self-resetting. Fig. 2 (not shown) illustrates a modified arrangement which may be provided with an auxiliary circuit to prevent reclosure of the contactors and the restoration of the field excitation should the contactor in the overload output line fail to open.
