Title: Magnetic element read-out
IPC: G11C7/02
Filed: 1962-09-03
Abstract: 943,387. Circuits employing bi-stable magnetic elements. SPERRY RAND CORPORATION. Sept. 3, 1962 [Nov. 1, 1961], No. 33653/62. Heading H3B. The sense winding 13 of a magnetic storage element 11 is coupled by a two-wire transmission line 19 to a load, a part of the transmission line being formed into a coil 21 which substantially attenuates spurious signals without noticeably attenuating the information signals from the sensed element. The arrangement operates on the principle that the oppositely-directed information currents in the two transmission line conductors 23, 25 mutually cancel, whereas the spurious currents are in the same direction and establish an inhibiting magnetic field in the coil. The magnetic element may comprise a thin magnetic film or a magnetic rod, and the transmission line may consist of a tightly coupled pair of wires, a coaxial cable, or a bifilar wire. In Fig. 1, a balanced load 27 terminates the transmission line, and in Fig. 2 a further length of line forming a second coil 22 is connected to an unbalanced amplifier load 29, the resistors 27 having a lower impedance to the spurious signals than the coil 22.

Filed: 1929-11-07
Abstract: 348,103. Coin-freed liquid-dispensing apparatus. RICHTER, L. and ASENBAUM, E., (trading as FRECALDO AUTOMATEN-HANDELS-GES. RICHTER & CO., 4, Rathausstrasse, Vienna.) Nov. 7, 1929, No. 34030. Convention date, Nov. 8, 1928. [Classes 27 and 116.] In a coin-freed machine for vending drinks of the kind wherein the drink is fed to a cup on a tray 3 which is moved through a normally closed opening 2 to a delivery position, the said opening being then closed again, a flap 9, pivoted at 12 and normally in a position 9<1>, closes a channel formed by walls 7, 8, along which the tray moves. The flap is opened by the outward movement of the tray and held open by an extension 11 thereon until the tray returns when it is again moved against the tray by a spring 10. The tray is moved by a cam 18 engaging an arm 19 secured to an arm 5 on a plate 4 which supports the tray 3, the cam being carried on a driving spindle 17 actuated after inserting a coin. When a cup, released from a container by a coin, comes under a nozzle 13, the latter, actuated by the spindle 17 through the cam 18 and sectors 21, 23, in mesh with a gear wheel 22, moves with the cup until this reaches the opening 2. Slides 16, which close the opening 2, are then moved apart by lazytong mechanism 26, 27, actuated by a cam 24 on the spindle 17 engaging a lever 25, and the tray 3 passes out to a delivery position. The opening 2 is then closed by the plate 4. The flap 9 in the position 9<1> prevents a cup, when delivered on to the tray, falling over, and in the open position forms part of the wall 7. The Specification as open to inspection under Sect. 91 (3) (a) describes also a means for normally closing the opening 2 which consists of a single slide which locks the plate 4 when the tray is in the delivery position. The slide is actuated from the driving spindle by.a crank mechanism. In a further modification, the tray is carried between two vertical walls which are arranged at rightangles and are pivoted on a vertical spindle at their junctlon. It is stated that the mechanism may be applied to a machine vending goods other than liquids. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to photographic cameras
IPC: G03B17/42
Filed: 1936-12-11
Abstract: 489,646. Photographic roll - film cameras. ZEISS IKON AKT.-GES. Dec. 11, 1936, No. 34127. Convention date, Dec. 11, 1935. [Class 98 (i)] Two sets of locking means are provided in a roll-film camera, one alternately locking the film feed and the shutter release, the other alternately locking the shutter release and shutter winding means. As shown, a cam disc 10 with two lugs 11 formed thereon, is connected to the film winding shaft 8 by a friction coupling. On the shaft 8 is also rotatably mounted a plate 14 with a lap which bears in one position against the shutter release spindle 16 under the action of a spring 19. A pawl 12 pivoted on the plate 14 is urged against the cam disc 10. An inclined face on the spindle 16 rotates this pawl, when the shutter is released, away from its locking engagement with the cam 10. The plate 14 is then swung over by the spring 19 and when the shutter release returns, it is locked by the plate which moves under a hub on the knob 2. Then, when the film is wound, the pawl rides on the cam 10 until near the end of the film feed movement, the lug 11 engages the pawl, causes rotation of the plate 14 and unlocks the shutter release. A spring 21 bearing against rests 22 on the cam disc prevent counter rotation of the latter. In order to prevent actuation of the untensioned shutter, a locking lever 23, Fig. 6, pivoted on the housing engages at its end with the tensioning ring 26. When the ring 26 is in its untensioned position, the lever 23 falls into a recessed portion and its other end prevents the member 24 from actuating the shutter release 29. When the ring 26 is tensioned, the nose of the lever 23 moves on a raised portion of the ring 26 and permits actuation of the release. When set for " B " or " T," a pin 27 on the setting disc moves the lever 23 away from its locking position.
