Title: Process for the production of cellular rubber articles of unlimited length
IPC: B29C67/24
Filed: 1936-04-07
Abstract: 466,629. Spongy and cellular rubber; coagulating latex. McKAY, R. F. (Soc. Italiana Pirelli) April 7, 1936, No. 10211. [Class 70] A process for making spongy or cellular rubber according to the principle of the invention set forth in Specification 411,202 comprises continuously supplying rubber dispersion to the lower end of a vertically-disposed mould 1, introducing as by means of tubes 6 a succession of bubbles of a gas having direct or indirect coagulating properties, and continuously removing from the upper end of the mould as by means of a conveyer 8 the coherent mass of coagulum so formed. The tank 4 may contain water or coagulant. The mould 1 may be of stainless steel or glass. The gas used may contain 3 to 5 parts by volume of carbon dioxide to 1 part of nitrogen. The dispersion may contain 1À2 gms. of diphenylguanidine (dormant coagulant) in every 200 gms. of 60 per cent latex containing 0À7 per cent of ammonia. The ends of the tubes 6 may be covered with elastic strips whereby the size and volume of the bubbles may be controlled. The tendency for the rubber to stick to the mould and the rate of production of coagulum may be varied by varying the rate of introduction and the coagulating strength of the gas bubbles and the pressure and coagulating tendency of the dispersion.

IPC: H04N7/12
Filed: 1974-03-07
Abstract: 1458580 Television RCA CORPORATION 7 March 1974 [8 March 1973] 10230/74 Heading H4F The synchronizing signals contained in a video signal are removed, the resulting synchronizing signal-free video signal being passed to the circuit output via an amplitude-adjusting potentiometer 54. Horizontal drive pulses 30 supplied to terminal 32 cause transistor 14 to conduct and transistor 50, which receives the input video signal from terminal 68, to be cut off during the horizontal synchronizing periods to provide, via potentiometer 54, a zero volt output at terminal 1 of switch 80. During the line scanning periods the input video signal is amplified by transistor 50 and passed via potentiometer 54 to terminal 1 of switch 80. The circuit shown may be used in a system for transmitting one frame of video information via an audio communications link, deletion of the synchronizing signal enabling a saving in dynamic range. Synchronizing information may be transmitted by a control signal at the start of each transmitted frame. The amplitude of the video signal at terminal 1 of switch 80 may be compared on an oscilloscope with "black" and "white" levels provided from terminals 2 and 3 of switch 80, the "white" level corresponding to the maximum voltage which may be transmitted by the audio communications link, and potentiometer 54 being adjusted so that the maximum amplitude of the video signal corresponds to this "white" level.

Title: Improvements in electromagnetically controlled hydraulic governors for electric metallurgical furnaces
IPC: H05B7/02
Filed: 1929-04-02
Abstract: 330,337. Tagliaferri, L. April 2, 1929. Regulaton, automatic.-The valve 19<1> controlling the flow of liquid to and from the hydraulic cylinder 8 operating a furnace electrode 1 is coupled to a liquid operated differential piston 29 fitted with an electromagnetically controlled rotatable valve 39 having longitudinal grooves 51 cooperating with radial passages 36 in the piston to control the flow of liquid therethrough. The valve 39 is resilientiy suspended and carries an armature 45 co-operating with an electromagnet 46. When the furnace is connected to the supply an electro-magnet 70 rotates the shaft 60 and a lever 65 mounted thereon moves the armature 45 to allow liquid to flow freely through the piston 29. The valve 19<1> is consequently depressed by the spring 32 to put the hydraulic cylinder in communication with the exhaust with a consequent lowering of the electrode. When the electrode contacts with the charge the electromagnet 46 is energized through the transformer 48 and the valve 39 is rotated to close the passages in the ,piston. The piston and the valve are consequently raised and the hydraulic cylinder is put under pressure and the electrode is raised to strike the arc. Stops 59 limit the upward movement of the piston. The armature 45 is normally held in contact with the bell crank lever by springs 60 attached to pins 60 on the armature and bell-crank levers 62 contacting with the piston. The hydraulic cylinder 8 and the piston chamber are fed from accumulators 17, 53 supplied from a rotary pump 14 and an oil pump 54 respectively. The water and oil are returned by pipes 26, 56. The piston exhausts to a chamber 27 enclosing the valve and its operating gear. The pipe 56 terminates at a level in the chamber such that the armature 45 and valve 39 are immersed in oil. A regulating resistance 71 is connected in parallel with the electromagnet 46. The distributing member of the valve 19<1> is of wedge shape so that its regulating effect may be varied by rotation. The valve 19<1> may be manually operated to control the electrode by a handwheel 22 mounted on a shaft carrying a cam 21 engaging the stirrup 20 connecting the valve with the piston.
