Abstract: 863,082. Kinematograph apparatus. FERNSEH G.m.b.H. July 15, 1957 [July 14, 1956], No. 22323/57. Class 97(1) [Also in Group XVI] Intermittent feed mechanism comprises means for intermittently clamping the film at the gate, a substantially closed box through which the film is led, the space within it being divided by the film, means to apply an excess pressure to the two sides of the film alternately, firstly to press the film against an arcuate guide and feed it through the gate while unclamped and then to expel the fed portion from the box, and means to prevent any reverse movement of the emergent film. In the form shown the film 1 is fed at constant speed by a sprocket 2 into a loop 3 preceding the gate 5. Beyond the gate the film passes through a chamber 13, which is slightly wider than the film, between apertured guides 20, 25 which differ in length by the length of one film frame. An alternating difference of pressure between the two sides of the film is produced by a piston 23 in a cylinder 22. A clamp 15 for the emergent film is operated by a cam 17. While the film is clamped, pressure is applied to the upper side of the film to press it against the guide 20 and feed one frame through the gate. The clamp 15 is then released while the film is held in the gate by clamps 7, 6 operated successively by cams 11, 10. The gate preferably has a register fin. Pressure is then applied below the film to press it against the guide 25 as it is drawn forward by the spring loaded roller 18 as it passes to the sprocket 19. The cams 10, 11, 17, as well as the crank 24 driving the piston 23, are all carried on the shaft 12. The sprockets 2, 19 may be rotated intermittently or replaced by other intermittent feed devices such as claws. The upper guide 25 may then be dispensed with or, if it is retained, the difference in lengths of the two guide members need not be exactly one frame. A separate air operated feed device may be provided also before the gate.

Abstract: 159,238. Hushes, H. I., and Hughes, D. A. Sept. 11, 1919. Spray carburettors.-A rich mixture or emulsion is formed in a branch Y to the main air passage 2 of a carburettor, the fuel being sprayed from opposed jets X, X<1> at a constricted part of the branch. The amount of fuel is controlled by two needle valves 10 worked together from a lay shaft V through links and oppositely-handed screws n<3>. The fuel enters the float chamber through the filter D and radial holes in the nut r<2>; it flows to an annular passage, y<6> around the jets through the duct E, filter d<4> and channel C. The float valve may be held down by a spring attached to the float chamber by the screw 7. The mixture throttle has two notches G, H, which form a by-pass for starting up with the throttle closed, a screw L being used to adjust the amount of passage through the notch H; in a modification the outlet of the branch Y projects into this notch. A spring- pressed throttle Q is used to close the main air passage at starting. The Provisional Specification states that the mixture throttle and the fuel valves may be controlled conjointly.

Title: Improvements relating to electronic switching circuits

Abstract: 693,893. Valve switching circuits. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Aug. 22, 1950 [Sept. 3, 1949], No. 22868/49. Class 40 (vi). A switching circuit for inserting blanking signals into a television waveform comprises a diode switch connected in series in the signal transmission channel, means for rendering the switch selectively conducting or non-conducting, and an additional circuit connected in shunt with the transmission channel and arranged to have a high impedance when the switch is conducting and a low impedance when the switch is non-conducting, whereby the transmission of signals via stray capacities or other capacities associated with the diode switch when the switch is non-conducting is reduced. In the arrangement shown in Fig. 1, television picture signals from a source 4 are fed to a load resistance 3 through a switching circuit comprising diodes 5 and 6 and are periodically blocked by means of positive voltage pulses from a source 11, which pulses render the valve 9 conducting and the diodes 5 and 6 non-conducting by sending the potential at the diode anodes negative (the cathode of valve 9 being returned to a negative potential with respect to earth). In order to prevent the diodes passing signals in their non- conducting states via their inter-electrode capacities, a further diode 12 (or alternatively a metal rectifier) is so biased that it is rendered conducting during the periods when the diodes 5 and 6 are non-conducting and thus presents a path between the diode anodes and earth having a low impedance compared to that of the capacities associated with the diodes. In a modification, Fig. 2, the diode 12 is dispensed with and its function is performed by the valve 9 which, when it is conducting, presents a low cathode-earth impedance owing to its cathodefollower action and thus provides a low impedance shunt path to earth for signals developed across resistor 8 when the diodes 5 and 6 are non-conducting. The Provisional Specification states that under certain conditions the diode 5 shown in both Figs. 1 and 2 may be dispensed with. Specification 682,159, [Group XL (b)], is referred to.
