Abstract: 1,153,744. Shutter mechanisms. RICOH K. K. Sept. 1, 1966 [Sept. 8, 1965], No.39055/66. Heading G2A. A photographic shutter device comprises a shutter release member 2 associated with a reciprocally movable lever 6 which holds the shutter 1 open in its operative position, in which position it is held against a spring-biased movement by an iron block 12 floatingly or resiliently mounted on the lever 6 and attracted by an electromagnet 15 which is energized on releasing the shutter, and de-energized after a time determined by a photo-cell, whereupon the iron block 12 is released, and the lever 6 turns and allows the shutter to close. The shutter 1 is held open by an abutment 1a thereon locking with a projection 7a pivotally mounted with the lever 6 and spring- biased against an abutment 6c on the lever 6, such that when the lever pivots under the action of its spring 10, the projection 7a pivots with it and releases the abutment 1a of the shutter. If the voltage applied to the electromagnet is insufficient to hold the iron block 12, the lever 6 pivots as the shutter release 2 is depressed, moving a shoulder 6b on the lever into the path of a projection 2b on the release member, preventing further depression thereof. The iron block 12 is mounted on lever 6 by springs 14 and its movement is restricted by studs 11 mounted on the lever and projecting through slots 13 in the block.

Abstract: 986,367. Hinges with stays. ATWOOD VACUUM MACHINE CO. Oct. 7, 1963 [Oct. 15, 1962], No. 39357/62. Heading E2F. A hinge 17 especially for a vehicle door comprises two leaves 18, 20 with knuckles through which a pin 22 extends, a friction arm connected to one leaf and passing between friction pads in a slot 26 in the second leaf providing resistance to relative movement of the leaves, the pads being removable only when the friction arm is withdrawn. The end of the flat straight arm 25 is pivoted by pin 24 to leaf 18 and extends between friction pads 27 which lie within and against the longer sides of the slot 26. The arm comprises two flat metal strips in contact near the pin 24, diverging over the portion 34 and with depressed end portions 32 riveted together and forming a stop 35. Friction resisting movement is therefore increased as portion 34 passes through the slot. The friction arm may be arcuate and in this case is either rigidly secured or pivoted to the first leaf. A modification is shown where the strips diverge from the pin 24 to the end and a rib in one of the metal strips may space them apart. In another modification two strips are embossed and then welded together. In a further modification the friction arm comprises a single piece of metal with a part embossed in opposite directions.

Title: Holder for a wire eroding electrode for spark erosion machines
IPC: B23H7/06
Filed: 1977-09-28
Abstract: The holder (11) carries a wire-shaped eroding electrode (12) which is guided on the legs (13, 14) of a U-shaped holding stirrup (15). On the one hand, the holding stirrup (15) can be moved in two coordinates in accordance with a path predetermined by a scanning device connected to a lever (8). On the other hand, it can be moved by a motor (21) in such a way that the eroding electrode (12) describes the envelope of a cone with an apex (20) which coincides with the bottom edge of a workpiece (5) to be machined. To this end, the holding stirrup is connected to a circular-arc-shaped bearing (32), the axis of rotation of which runs through the cone apex (20). Via a movable coupling piece, the bearing (32) is connected to a second bearing of the same type which is arranged offset by 90 DEG from this bearing (32) and at the same height. The second bearing is movably connected to a bearing part (22). The drive motor (21) fastened to the bearing part (22) is in drive connection with the holding stirrup (15) via an eccentric and an auxiliary universal joint. This holder can be constructed simply and robustly and it permits the adjustment of the electrode (12) on the envelope of a cone with high precision of movement. <IMAGE>

In character recognition equipment wherein characters to be recognized are positioned in an aperture and scanned in columns, a constantlyupdated number is stored for each line of scanning signal elements perpendicular to the columns, the number specifying the number of adjacent " ones " (the value produced by the border around the aperture) encountered in the scanning signal elements, the number being zeroized on reaching a " zero " in the line, and a signal is produced when such a number exceeds a minimum, the disappearance and appearance of this latter signal, on the scan crossing the upper and lower boundaries of the aperture respectively, being used together with the scanning signal elements to define the aperture position. The minimum initially corresponds to the width of the first side border of the aperture (but is later altered to correspond to the width of a character). The aperture position is specified by the time position of " window signals " in a circulating store, which stores window signals produced as above during the latest column scan which crossed the aperture (window) but not any character. The window signals are used for gating scanning signal elements to recognition circuitry, to remove " ones " produced from the aperture surroundings (border). The detailed disclosure is largely as in Specification 1,126,601, which is referred to, except for the following modification. Since the upper and lower boundaries of the aperture may not be exactly perpendicular to the columns and since the digitizing of the scanning signal into binary elements may produce errors, mistaking part of the border for part of a character is prevented by taking the window signals to correspond not to the interval between the upper and lower aperture boundaries but to this interval minus one or more scanning elements at each end.
