Title: Magnetic unit record cards
IPC: G06K1/12
Filed: 1960-06-27
Abstract: 954,057. Statistical record cards. INTERNATIONAL BUSINESS MACHINES CORPORATION. June 27, 1960 [June 30, 1959], No. 22388/60. Heading G4M. A record card 20 Fig. 1 has an array of magnetisable spots 21 some of which are magnetised by alternating current to record data. The direction of the lines 22 of maximum magnetisation is diagonal of the spot. The recording and sensing is effected by a head 24 Fig. 2 having an oblique slot. The record is passed under the head moving longitudinally or sideways. The advantage of using a diagonal magnetisation is that at the middle of the mark a maximum length of magnetised material is sensed, giving a signal 1.4 times as great as that derived from a transverse magnetisation and a transversely slotted head. In operation, the recording may be effected by first magnetising all the spots and then by using a mask erasing all but those required to record the data. Specification 515,183 is referred to.

Abstract: 767,699. Photographic developers. KODAK, Ltd. Aug. 3, 1954 [Aug. 3, 1953], No. 22505/54. Class 98(2) , A photographic developer composition, in wet or dry form, comprises an alkaline material, a 3-pyrazolidone silver halide developing agent, and reductone or an amino-substituted aromatic acid derivative thereof, e.g. the p-aminobenzoic, m- or paminosalicylic. or sulphanilic acid derivative thereof. The 3-pyrazolindone developing agent may have, the general formula wherein R 1  to R 5  can be H or alkyl or aryl groups, substituted or not. Numerous 3- pyrazolidones are specified, including 1- phenyl-2-acetyl-4 : 4-dimethyl-3-pyrazolidone. The activity and stability of the developer are both increased as compared with developers not containing both the reductone (or derivative thereof), and the 3-pyrazolidone compound, and when the developer is free from silver halide solvents, it behaves as a strong surface latent image developer. In examples, data illustrating the activity of developers containing 1-phenyl-3-pyrazolidone and the reductones from glucose, galactose, 1-arabinose, levulose, and lactose are given. 'In a dry developing composition, the alkaline material may be sodium, carbonate, caustic alkaline, or sodium perborate.

Title: Improvements in or relating to control mechanism particularly for use with electric switches
IPC: H02B15/00
Filed: 1932-08-18
Abstract: 384,960. Retractive switches. WESTINGHOUSE ELECTRIC & MANUFACTURING CO., East Pittsburg, U.S.A. -(Assignees of Ringbloom, C. A. ; 337, Mercer Street, Turtle Creek, Pennsylvania, U.S.A.) Aug. 18, 1932, No. 23152. Convention date, Sept. 10, 1931. [Class 38 (v).] Actuation; indicators.-A switch for controlling the operation of a circuit-breaker comprises a shaft 11 which has an operating-handle 14 and is mounted for rotational and limited axial movement in a frame 12 mounted on a switchboard 13. The shaft 11 carries a drum 17 carrying two contact-bridges 18, 21, arranged at right-angles, and a circular contact 23. Stationary contacts 19, 22 are arranged in the circuits of closing and tripping coils respectively of a circuit-breaker, a pair of contacts 24 being arranged in series with the other pairs. Thus on rotating the drum 17 one of the pairs of contacts 19 or 22 are bridged and, if the drum is then moved to the right, contacts 24 are bridged by the member 23 and circuit is completed to open or close the circuit-breaker. Mounted loosely on the shaft 11 is a sleeve 36 which is prevented from axial movement by the engagement of a flange 37 with a fork 38 and is biased to a central position by a spring 39 whose ends embrace a pin 41 on the sleeve and a pin 42 on the casing. A member 46 fixed on the shaft 11 has two diametral slots at right-angles into which engage a clutchmember 45 on the sleeve 36 and a spring 55 retains these parts in engagement. To operate the switch, the handle 14 is turned through a right-angle thus preparing a circuit through one of the bridges 18, 21, the spring 39 being strained. The handle is then pulled to the right to complete the circuit through contacts 23, 24. The movement disengages the clutch 45, and the sleeve 36 returns to neutral position. When the handle is released, it returns axially due to spring 55 and the clutch 45 engages a slot in the member 46 at right-angles to the one previously engaged and locks the handle on the new position. The handle is ovalshaped and has an imitation bridging-connector on its outer surface, while imitation busbars are positioned on the switchboard to indicate diagrammatically whether the switch has been operated to open or to close the circuitbreaker. A lug 54 on the frame engages an arcuate slot in the member 46 to limit its motion to a right-angle and also to prevent axial movement during turning. The ends of the slot are formed as through holes to allow of axial movement and also to prevent turning while the circuit is completed in the drawn-out position.
