Title: Improvements in or relating to a machine for filling and cooking dry batteries
IPC: H01M6/08
Filed: 1931-06-12
Abstract: 376,458. Galvanic batteries. BUMKE GES., H. A., 8, Chausseestrasse, Berlin. June 12, 1931, No. 17135. Convention date, Sept. 4, 1930. Addition to 354,094. [Class 53.] The machine for the filling and cooking of dry batteries described in the parent Specification is modified by the use of carrier frames for the pots, whereby the number of step by step movements of the machine, particularly of the control plate for the cooking stage, may be reduced. In the form illustrated in the drawings, pots provided with cardboard discs, for example as described in Specification 337,869, [Class 53, Galvanic batteries], are periodically dropped through a tube 2 in transversely arranged groups, e.g. in rows of 5, guide sleeves 14 ensuring proper introduction of the pots into their holders. These holders are arranged in transverse and longitudinal rows in a potcarrier frame 4, a slide beneath the holders serving to support the pots. The baseplates of the frames 4 have notches 9 separated by distances equal to the distances between succeeding transverse rows of pot-holders, and pawls 5 engaging in these notches serve to impart the necessary step by step movement to the pot-carrier frames along guides 3. The pots are fed with electrolyte on passing under a pump similar to that disclosed in the parent Specification and situated remote from the cooking bath. Cores are then inserted by hand or automatically, and a centring plate 25 is laid on the pots, which are then transferred to a cooking and cooling apparatus similar to that described in the parent Specification, but suitably modified, as illustrated in Fig. 12, to take whole carrier frames instead of single pots. The drive of the cooking and cooling mechanism is so timed that stoppage is effected only when a pot-carrier frame has been advanced through its own length.

Title: Improvements in or relating to photographic cameras adapted to employ flash lamps
IPC: G03B9/70
Filed: 1940-12-03
Abstract: 540,523. Photographic cameras combined with flash-lamps. KODAK, Ltd. (Eastman Kodak, Co.). Dec. 3, 1940, No. 17223. [Class 98 (i)] A camera having a socket for a flash-lamp includes means which, when a lamp is inserted, is moved to a position in which it prevents, after the shutter has been released, operation of one or more of the shutter releasing, shutter setting, or film winding mechanisms, until the burnt-out lamp is withdrawn, thereby preventing exposure failures due to omission to insert a new lamp. The invention is described as applied to a rollfilm camera having a two-plate focal-plane shutter of the form described in Specification 534,063 which is set simultaneously with the winding of the film. Rotation of the film-winding shaft 23 causes a gear 24 to rotate a multilated gear 25 to which is eccentrically pivoted a link 26 connected to an arm 27, which is thus moved clockwise and engages and operates the setting-lever (not shown) of the shutter. When the shutter is set, the mutilated portion of the gear 25 allows further rotation of the shaft 23 for completion of the winding of the film, this operation being terminated when a pin 38 carried by a disc 39 Fig. 5, rotatable with the film sprocket engages a lever 33 and turns it so that a pawl 35 formed on it engages a ratchet 36 on the shaft 23. Depression of the shutter release 12 to operate the shutter latch member 8 also moves the lever 33 axially on its pivot, so disengaging it from the pin 38 and allowing it to rock under spring action to remove the pawl 35 from the ratchet 36. At the same time, a lug 42 on the lever 33 is disengaged from a lug 43 on the multilated gear 25 which is then turned by a spring operating on the link 26 so that it re-engages the gear 24. The parts are now in position for re-setting the shutter and winding the film. Should, however, a flash-lamp be in the socket 57, the base of the lamp by engagement with a pin 58 carried by a pivoted arm 46 moves the latter to the position shown in Fig. 4. In this case, when the shutter release 12 is depressed, an offset portion at the upper end of a spring-pressed arm 52 pivoted to the arm 46 enters a groove 56 in the release member and so retains it in the depressed position. At the same time, a projection 50 on the arm 46 is brought opposite a lug 41 on the lever 33, so preventing its rocking to remove the pawl from the ratchet 36. A second actuation of the shutter release or of the film-winding and shuttersetting knob is thus prevented until the burnt-out flash-lamp has been removed, allowing the arm 46 to return to the position shown in Fig. 3. The flash-lamp may be fired in synchronism with the shutter in the way described in Specification 540,476.

Abstract: 925,199. Shirt collars. PHILLIPS-VAN HEUSEN CORPORATION. May 20, 1959, No. 17226/59. Class 141. A single ply collar has a fabric patch 7 on its inside face at each end which is secured to the collar initially by stitching along the lower and forward edges 6, 10 of the patch after which it is held under tension transversely of the collar whilst its upper edge is secured to the collar by stitching 18. The tensioned patch tends to curve the collar convexly at its forward end to resist the normal tendency to curve outwardly and upwardly while being worn. The stitching 18 may be a separate row of stitching, or may be part of the stitching securing the collar to a neckband of a shirt or collar. The patch may be formed of material possessing greater shrinkage characteristics than those of the collar. A stay pocket 14 is secured to the patch 7 and is positioned between the patch and the inside face of the collar. The edges of the collar and patches 7 are inturned, and a binding strip 4 is stitched to the inner face adjacent the lower edge.
