Filed: 1922-08-02
Abstract: 184,187. Salin, (nÚe Levy), R. Aug. 3, 1921, [Convention date]. Rattling of doors, preventing.-A latch fastening for motor vehicle doors used in combination with the anti-rattling cone and socket devices described in Specifications 159,841 and 166,145 has a latch bolt with an incline on the side opposite the usual bevel engaging a correspondingly inclined part of the staple, to ensure close fitting of the door and to wedge the cone member into its socket. In the form illustrated in Figs 1 and 2, the latch bolt d may be operated by the vertical lever f, pivoted at f<1> to the casing b, or by a follower h turned by a squared spindle to operate the lever f by means of the sliding piece h'. The side k of the latch bolt d, opposite to the bevel, is inclined to engage a similar incline k' on the edge of the staple a. A conical stud i' projecting from the casing'engages a bent-over socket i on the staple a, to align the door and prevent rattling. When the spring e shoots the latch forward, the wedge action between the bolt and its staple forces the stud i<1> into its socket i, firmly holding the door. This construction of latch bolt permits of a tight fit in the staple even after wear.

Title: Improvements in or relating to Photographic Apparatus
IPC: G03B7/085
Filed: 1967-05-08
Abstract: 1,188,994. Exposure control apparatus. INTERNATIONAL POLAROID CORP. May 8, 1967 [May 12, 1966], No.21294/67. Heading G2A. An exposure control has an ambient light aperture control system C Fig.1 for selecting an exposure aperture appropriate to the scene light as detected by a photo-cell 22 and an exposure time control system A for timing the exposure responsive to the light level during exposure as detected by a photo-cell 16. An artificial light aperture control system B having a focus control 11 can be connected to the system A when it is required to use flash. Under natural lighting conditions the system B is disabled. Exposure time control Shutter blades 26, 27, Fig.2, are slidable across objective 25 to effect exposure. Blade 27 is retained in cocked position against a spring 29 by a lever 30. Shutter blade 26 has a keeper 45 positioned adjacent electromagnet 46. On depression of button 54, a switch S-1 closes, a latch 37 rotates to release sliding bar 33, thereby causing lever 30 to release shutter blade 27 which moves to the left to effect exposure. A switch S-2 is opened by a latch mechanism tripped by the blade 27. After a delay, electromagnet 46 is deenergized to release blade 26. The electromagnet 46 is included in an R.C. trigger circuit Fig.3 (not shown) which includes a photo-cell 88 exposed to scene light. Aperture control ambient light Aperture blades 97, 98, Fig.4, are urged by springs 108, 109 to rotate clockwise. Solenoids 112, 113 retain the blades in their cocked positions. Apertures 126, 127 of different size are provided in the blades. An electric circuit (135), Fig. 5 (not shown) selects the aperture appropriate to the level of light sensed by photo-cell (148) by energizing the solenoid coil (136) or (137) depending on the bias voltages of transistors (138), (139). In low light conditions, both selenoids 112, 113 Fig.4 remain energized, such that exposure takes place through a larger fixed aperture 116. Aperture control with flash-lighting Blades 150, 151, Fig.6, are caused by spring 153 to rotate in opposite directions to decrease an aperture formed by openings 157, 158. Openings 159 and 160 provide a variable aperture for a photo-cell (148) Fig. 5 (not shown). A pin 167, Fig.6, engaging surfaces 165, 166 locks the blades 150, 151 to provide for a maximum aperture when flash is not being used. A pin 172 is carried by an arm 173 of lever 174 pivotally mounted at 175. A slidable plate 178 carries a pin 177 engaging slot 179. A pin 185 coupled to a lens focusing mechanism, engages a tab 182. As focusing is carried out plate 178 is moved to adjust the blades 150, 151 thereby adjusting the exposure and photocell apertures.

[Also in Group XVI] A postal franking-machine (see Group XVI) comprises a plurality of selector knobs carried on a set of concentric shafts on a first axis about which the rotary printing element rotates, a second set of concentric shafts mounted in the rotary printing element on an axis parallel to the first axis and carrying the printing-wheels, the shafts of the first set being individually geared to the corresponding shafts of the second set, whereby individual rotation of any one of the selector knobs can position an appropriate printing-wheel. A gummed, franked label for sticking on a parcel or package is printed with a stamp showing the amount of postage by a rotary printing drum 4 mounted in a casing 1 and rigidly secured to a tubular shaft 42. The shaft 42 is rotated by a handle 6, which causes a length of gummed paper to be severed from a roll in a storage compartment, printed and issued from the machine in known manner. Wheels 10, 11, 12 carry type on their peripheries and can be rotated to vary the value of the label printed by means of knobs 7, 8, 9 mounted on coaxially-arranged shafts 13, 18, 22, respectively. The shafts 13, 18, 22 carry gear-wheels 26, 27, 28, respectively, which mesh with gears 32, 33, 34, Fig. 3, mounted on shafts 29, 30, 31 each of which carries at its other end a further gear (as 38, Fig. 2) meshing with one of three further gears 35, 36, 37. The gears 35, 36, 37 are mounted on concentric shafts 39, 40, 41 respectively contained within the tubular shaft 42 and carrying cams 47, 48, 49 which project through slots 50, 51, 52 in the tubular shaft 42. As the knobs 7, 8, 9 are rotated to set the type wheels the cams 47, 48, 49 are rotated by means of the gearing described above and position sliding teeth 46 so that they either project from or are retracted into carriers 43, 44, 45, therefor, as described in Specification 605,624, mounted on the tubular shaft 42. When the handle 6 is actuated to print a label the projecting teeth 46 advance counters 53, 54, 55 by an amount corresponding to the value printed by the typewheels, whereby the total value of franked labels printed is indicated. The drive for the counter 55, Fig. 4, comprises a ratchet 56 engaged by a non-return pawl 57. As the shaft 42 turns through one revolution the ratchet is rotated to a greater or lesser extent depending upon the number of teeth 46 projecting from the carrier 45 and drives the counter 55 through gears 58, 59. The drives for the other counters are similar. Specification 710,864 also is referred to.
