Title: Improvements in or relating to index selector devices
IPC: B42F17/34
Filed: 1957-02-08
Abstract: 829,755. Card index selectors. LAUGHTON & SONS Ltd., [formerly JARRETT, RAINSFORD & LAUGHTON Ltd.], and LAUGHTON, M. Jan. 28, 1958 [Feb. 8, 1957], No. 4346/57. Class 146(1) An index selector device in a card or sheet index, which is arranged in a casing having a base and a hinged cover in the manner of a book, is arranged detachably within the front edge of the hinged cover to move therewith and comprises depressible keys or the like by which the operator initiates the selection of a particular card, and card-engaging means which are individually actuated to engage a card when the corresponding key is depressed, and so raise from the base with the cover all the cards above the one required. As shown, the cover a is hinged to the base b on pins h and urged upwardly by torsion springs, and is normally retained in closed position by a spring catch j which is released when an index selection is made by any one of a number of depressible keys d. The selector device, which is fitted removably as a unit in the front edge of the cover a comprises a frame n supporting a transverse rod m on which the keys d are pivoted, and a metal strip supported on an angle bar q of the frame n and formed with as many fingers e as there are keys. The spring fingers e are bent to pass under the keys d and in contact with the nose parts s thereof, and the ends of the fingers are arranged below the stepped ends of a pack of index cards c. When key d is depessed, a tooth x on the carrier n releases the catch j to release the cover a, the corresponding finger e is urged forward beneath the index cards c, and the cover swings open, raising all the cards in the index above the card corresponding to the key which was depressed. The base b, and cover a, and carrier n may be of moulded plastic. A recess 3 in the base may accommodate a note pad 4, and the base is weighted by a metal plate 1.

Title: Improvements in or relating to high power electric circuit-breaker with device permitting tensioning and relaxation of the closing spring
IPC: H01H3/30
Filed: 1950-02-21
Abstract: 667,606. Automatic circuit-breakers. NAAMLOOZE VENNOOTSCHAP FABRIEK VAN ELECTRISCHE APPARATEN VOORHEEN F. HAZEMEIJER & CO. Feb. 21, 1950. [Feb. 25, 1949] No. 4426/50. Class 38 (v). The closing spring 11 of a circuitbreaker is stressed and released by a single manually or mechanically rotated cam. In one form, Fig. 2, a stepped snail cam 8 driven by a motor 16 through gearing 14, 15, co-operates with a roller 9 on a rod 10 connected to the spring 11. The roller may, as shown, normally bear on the highest point of the cam, in which case the circuitbreaker 1 is closed as soon as the motor is started by a push-button 22, or, alternatively, it may bear against the lowest part so that the spring has first to be stressed when the motor starts. The cam may also be stopped in an intermediate position after straining or release of the spring and has a pin-andslot connection 17, 18, with the gear 14 so that upward movement of the roller 9 when it passes to the lowest cam-point is not delayed. The rod 10 has a spur 12 cooperating with a lug 61 on contact rod 6, an opening spring 5 being stressed whilst the contacts are held closed by a releasable catch 7. The motor 16 remains energized, after release of the button 22, over contacts 19, 20 until the gap in contact 19 comes opposite contacts 20. In a modification, Fig. 3 (not shown), the roller 9 is carried by a pair of bellcrank levers connected to the upper end of rod 10 and lost motion similar to that shown in Fig. 4b is provided between the gear 14 and the cam. In a further modification, Fig. 4, a stepped face cam 41 may be driven by a motor 49 through gearing 50, 51, the gear 51 being freely rotatable on a spindle 52 and being fixed to a sleeve 53 having lost-motion in a hole 54 in the cam. A switch 56 is opened to stop the motor by a projection 55 on gear 51 when the spring has been stressed. The cam may also be rotated by a handle 57 fixed to spindle 52, which also carries a disc, having a part 59 co-operating with a pawl 60 on gear 51 so that when the motor is running the pawl slips over the edge of the part 59, but when the part 59 is turned by hand the pawl rotates the gear 51. A spring plunger 61 co-operating with a part 58 of the disc locates the cam in its spring- stressed position. The cam preferably has on either side of the step a circular part, respectively permitting the spring to be fully released, and the operating mechanism to be set before the spring is released.

Abstract: 1,166,712. Film projection apparatus. BELL & HOWELL CO. Jan. 31, 1967 [May 10, 1966], No.4585/67. Heading G2J. In a flat ficke reader, the film is held between glass plates (200, 210, Fig. 9, not shown) in a holder frame (110, Fig. 4, not shown) movable horizontally and vertically to bring a selected picture to the projection position between lamp 35 and lens 46, Fig. 2, movement to the limit of the vertical scan automatically opening door 28 and separating the glass plates for removal or insertion of a film. Frame (110, Fig. 4, not shown) is movable horizontally along shafts (106, 107) by rack (113) and an elongated pinion (116) manually rotatable by means of knob (127) and a chain and sprocket system. The vertical movement is by means of pinions (89) on a common shaft (90) engaging racks (87) on the frame bracket (83) carrying shafts (106, 107). Shaft (90) is manually rotatable by knob (104) through worm (97) and gear (100) on shaft (101). Frame (110) is counterbalanced vertically by spring and cord 131, 137, Fig. 2. The glass plates rest in tracks (144, 147, Fig. 10, not shown), defined by L-shaped members (143, 146) of plate holder slides (141, 142). The plates are pressed together by spring clips (150, 155) until cammed apart the unequal arms (163, 163<1>) and (173, 173<1>) of cranks (162, 172) pivoting on slides (141, 142) and interconnected by actuators (167 and 177). As frame 110 moves to its vertical limit, arms (180, 190) of the actuators first open door (28) by engaging lug (228, Fig. 9, not shown), after which further movement of the frame engages surfaces (183, 193) of the arms (180, 190) thereby pivoting the actuators about shaft (107) to operate cranks (162, 172). A spring-loaded ball detent retains the frame in its limit position. The projected image is directed by a mirror 38, adjustable by screws 39, on to the screen 24. Lens (46) is rotatable for focusing by a gear (50, Fig. 5, not shown), engaging worm (51) on the shaft (53) carrying focusing knob (56). A Dove prism 47, Fig. 2, is rotatable about the optical axis by sprockets 67, 70 and chain 68, to rotate the projected image on the screen. A fan 71 cools the lamp and interior of the reader.
