Title: Improvements in automatic make-and-break devices for the electrical equipment of motor vehicles
IPC: H01H35/40
Filed: 1931-02-23
Abstract: 359,351. Actuation of switches. SUDER, G., 71, Rue Donis-Papin-Pantin, Seine, France. Feb. 23, 1931, No. 5618. [Class 38 (v).] Pneumatic actuation.-A device for breaking the coil ignition circuit of a motor car engine on stoppage of the engine, comprises a piston 4 in a cylinder 1 connected by a pipe 8 to the induction pipe 10. The cylinder 1 is closed by a corrugated diaphragm 17 supported by a cupped disc 18. On starting the engine, the reduction of pressure lifts the piston and makes contact with a spring-mounted contact 6 on an insulated terminal 15. A chamber 11 provided with small orifices, retards the flow of gas and prevents the sudden return of the piston under gravity during sudden acceleration. In a modification, an insulating button carried on the top of the piston presses together two insulated spring-mounted contacts. In engines which have to be started with the throttle wide open, an auxiliary shutter is mounted eccentrically in the intake pipe to produce a sufficient reduction of pressure for operating the switch. When the engine starts, the shutter assumes a position lengthwise of the intake but closes the intake again when the engine stops.

Title: Improvements in or relating to television camera iris control mechanisms
IPC: G03B9/10
Filed: 1954-02-25
Abstract: 739,451. Iris diaphragms. GENERAL PRECISION LABORATORY, Inc. Feb. 25, 1954 [July 30,1953], No. 5622/54. Class 97 (1). In a multiple lens television camera, alteration of the setting of the iris of a lens as it is moved into and out of the operative position is avoided by the provision of an iris control shaft which rotates the iris control ring of the lens, when it is in the operative position, through a lost motion connection. Preferably, the lost motion mechanism is between the control shaft 22 and the gear wheel 23 and may comprise a pin and slot connection therebetween. As shown, the lens turret 15 is rotatable about the boss 13 on camera housing 12 and is fastened to gear 14. Rotation of the shaft 19 brings each lens into the operative position in which the sector 21 of the iris control ring 32 of the operatively positioned lens 16 meshes with the gear 23 rotatable on the iris control shaft 22 which passes eccentrically through boss 13. Disc 24 is fast on shaft 22 and pin 26 on gear 23 passes through a slot 25. The slight relative rotation allowed by the pin and slot connection enables the lens to be changed without disturbing the iris setting, providing the gear 23 turns more easily than the sector 21. To ensure sufficient frictional resistance a button 33 may be mounted in ring 32 to bear against the turret 15. A leaf spring arrangement 29 is provided to centre the pin 26 in slot 25 when gear 23 is not engaged with a sector 21. Specification 670,581 is referred to.

Abstract: 981, 435. Photo-electric detection of bank note security thread in continuous paper web. FERGUSON RADIO CORPORATION Ltd. March 27, 1963 [Feb. 14, 1962], No. 5725/62. Heading G1A. Apparatus which indicates the presence of a gap 11a of length exceeding a predetermined amount in an opaque thread 11 running longitudinally in a web of paper 10 comprises means for moving the web longitudinally, means for repetitively scanning the web in such a manner as to generate an electric pulse each time the thread is scanned, and means responsive to the absence of pulses for giving the said indication. In the embodiment shown light from a lamp 12 having a reflector 13 and a diffuser 14, is directed through the paper and an image of the illuminated area which includes the security thread 11 is formed by a lens 21, on the underside of a rotating disc 18 having radial scanning slots 19. The disc 18 which is driven by a motor 20 at a speed synchronized with the longitudinal speed of the paper 10, passes the scanned image through an adjustable aperture 22 on to the window 25 of a photomultiplier 26 which emits a train of pulses, each pulse corresponds to a scan by each of the slots 19, when the thread is present. A train of counting pulses related to the scanning rate is derived independently and counted by a binary chain in a logic circuit 31. Each "thread" pulse received cancels two "counts" so that the counting chain tends to zero when the thread 11 is present but if the chain has counted seven without a "thread" pulse being received, this being equivalent to a gap in the thread of the said predetermined amount, a fault signal is triggered. In an alternative embodiment, the logic circuit 31 includes an analogue time counting device comprising a capacitor charged by a steady current and discharged by the integral of "thread" pulses from the photomultiplier. In this embodiment the web speed may be variable and the motor 20 is run at constant speed so that the pulses from the photomultiplier have a constant repetition frequency. When a gap occurs in the thread, the pulses cease and the charge on the capacitor rises and when the voltage across the capacitor exceeds a predetermined value a fault signal is triggered which operates an alarm or indicator or stops the paper. The circuit used in this embodiment includes a limiting amplifier, a pulse shaper, discharge gate and a Schmitt trigger all utilizing transistors (Fig. 2 not shown).
