Title: Improvements in and relating to synchronous motor clocks
IPC: G04C15/00
Filed: 1932-08-25
Abstract: 392,035. Electric clocks. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Allgemeine Elektricitõts-Ges.; 2, Friedrich Karl-Ufer, Berlin.) Aug. 25, 1932, No. 23829. [Class 139.] Winding-apparatus, electric.-A clock driven directly by a synchronous motor which also winds up the spring of an auxiliary driving mechanism which takes over the drive when the supply current fails, is adapted to be converted into a spring-driven clock wound by an electric motor, by fixing a detachable locking member 24, Fig. 5, over the pillars 27, 28, Fig. 1. The time-indicating parts 11 are normally driven directly by the motor 2, 3, through gears 4, 5, 7 (mounted on 5), 8, and shaft 10. Also gearing with planet wheel 7 is a wheel 9 which has one tooth more or less than wheel 8 and is rigid with a gear wheel 12 rotatable on shaft 10. The wheel 12 is geared through wheels 131, 13, 15<1> to a wheel 15 carried by an arm 14 pivoted coaxially with wheels 13, 13<1>. The gear 15 is adapted to be swung into mesh with a wheel 19 driven by the spring 16 through gearing 17, 18 under the control of an escapement (not shown). The spring 16 is wound through gear wheel 23 by a pawl 22, pivotally mounted on a lever 21 pivoted coaxially with 23 and rocked by an eccentric pin 20 on wheel 4. When spring 16 is fully wound the biasing spring 29 yields against the reaction thereof to prevent overwinding. With the locking member 24 removed, the arm 14 is normally held up magnetically by the stator field of motor 2 or by a relay, and gear wheel 13 is locked, for example by a projection (not shown) operated by movement of arm 14, the motor 2 driving the time-indicating parts 11 directly as above. Should the currents fail a biasing spring (not shown) rocks the arm 14, the gear 15 meshes with wheel 19, and the parts 11 are driven by the spring 16 through 19, 15, 13, 12, 9, 7, 8, the inertia of the motor rotor maintaining wheel 5 stationary. When the locking member 24 is attached, as shown in Fig. 1, a projection 25 thereon locks wheel 5, the projection 26 forces the wheel 15 into mesh with 19 so that the spring 16 drives, and simultaneously the wheel 4 is shifted axially out of mesh with wheel 5 against the action of a spring, to enable the motor to continue to wind the spring 16. Specification 389,908 is referred to.

Title: Improvements in and relating to information storage devices
IPC: H01J31/62
Filed: 1959-07-13
Abstract: 895,363. Semi-permanent data storage. INTERNATIONAL BUSINESS MACHINES CORPORATION. July 13, 1959 [July 11, 1958], No. 24019/59. Class 106 (1). [Also in Group XL (a)] A semi-permanent storage member having a light-reflecting surface is bombarded with ions to cause a regional alteration of the reflection coefficient of the surface, and means are provided to detect such alterations. As shown, a source 2 located in an evacuated tube emits an ion beam which is directed by a deflection yoke 7 against a plate of glass 4. The intensity of the beam is determined by the potential of an electrode 5 controlled from a source of information. The ions in striking the glass plate cause a regional decrease in the density of the atoms at the surface with a consequent increase in the index of refraction. This in turn reduces the coefficient of reflection. The glass plate is then scanned with a light spot as from a conventional cathode-ray tube 10 and the reflected light sensed by a photo-cell or photomultiplier tube 13 from which an electrical signal is applied to an amplifier 14 to derive an output representing the information stored. The glass plate may be removed from the tube. Information is erased by heating the plate. The use of argon or nitrogen ions is mentioned.
