Abstract: 1,264,227. Endless belts feeding cylindrical electrodes in furnaces. ELEKTROKEMISK A.S. 16 May, 1969 [21 May, 1968], No. 25046/69. Heading B8A. [Also in Division H5] A rotary feed mechanism for progressively advancing a cylindrical body in the direction of its axis, comprises an endless flexible driving belt 6 wrapped in a double length around the majority of the circumference of the cylindrical body with the inner run of the belt constrained in a helical disposition and in frictional engagement with the cylindrical surface of the body. The belt passes around parallel end rollers 9, 10, and is guided by means of guide members 7, 8, mounted between the inner and outer runs of the belt. The end rollers and/or the guide members maintain the required angle of helical pitch of the belt relatively to the axis of the cylindrical body. The end rollers and the guide members are carried by a drive housing 5 which surrounds the cylindrical body and is rotatable coaxially with respect thereto but is fixed against axial displacement. Means 11 are provided for rotating the housing relatively to the cylindrical body to cause the belt to roll around the body. As shown, two separate mechanisms are arranged to be driven in opposite directions of rotation by gearing 11, so as to feed vertically an electrode 1 downwardly into an electric furnace (not shown). The helical pitch angle is equal and opposite in respect of the two mechanisms. This prevents rotation of the electrode 1 relative to its suspension frame 3 and holder 2. The belts are formed with parallel longitudinal recesses to cooperate with the rollers 9, 10 and guide members 7, 8.

Abstract: 1,266,101. High speed cameras. SINGER-GENERAL PRECISION Inc. Feb.10, 1970 [Feb.13, 1969], No.6369/70. Heading G2A. A high speed camera has an image intensifier tube 16 between the objective lens 10 and the film, with means for automatically gating the tube according to sensed lighting conditions. As shown, light passing through the lens 10 and a rotatable filter disc 12 falls on a semi-transparent mirror 14, a major portion being reflected into the input screen of the image tube. The light which passes through mirror 14 falls on a photo-multiplier tube 18. The output of the photo-multiplier tube is coupled to the input of an amplifier 20, whose output is coupled to the input of an amplifier 24. This has a variable feedback resistance 28 controlled by an external knob calibrated in ASA numbers to provide film speed compensation. The output of amplifier 24 is coupled to a voltage integrating circuit comprising amplifier 34 shunted by switch 36 which can select any one of four values of capacitance each corresponding to one the neutral filters in disc 12, which is coupled to the switch. Thus adjustment of switch 36 selects both a particular filter (i.e. a particular light level to be sensed by the photo-multiplier 18) and the corresponding value of the capacitance in the integrator circuit. The output of the integrating amplifier 34 is coupled to a threshold amplifier 40 which passes a signal when a minimum reference voltage has been supplied to it. The output of amplifier 40 is coupled to a one-shot multi-vibrator 68 which, via a vacuum tube 70, applies a cut-off voltage to the gate of the image tube 16. The image tube is started by a switch 72, which supplies a signal via a one-shot multi-vibrator 82 and a vacuum tube 84, producing a positive voltage on the gate of the tube 16. The signal from the film speed compensation amplifier may be monitored by a circuit which causes one of three lamps 58, 60, 62 to light up and thus indicate whether the filter 12 which has been selected is suitable, or too dense, or not dense enough. The tube 16 itself uses fibre optics 90 at the focal plane, as insulation between the high voltages on the tube elements and the metal parts of the film magazine. Since the movement of the film causes rapid wear on the fibres, an additional and readily replaceable panel 92 of fibre optics is interposed between the tube fibre optics 90 and the film magazine. The camera can be used for single frame or multiframe (i.e. cine) exposures, and the lens can be focused manually, or cyclically by a motor 88.
