Title: Television telephone system
IPC: H04N7/14
Filed: 1964-04-30
Abstract: 1,058,725. Television telephone systems. TOKYO SHIBAURA ELECTRIC CO. Ltd. April 30, 1964 [April 30, 1963 (2)], No. 17988/64 Heading H4F. In a television telephone system the transmission of speech signals over a telephone line are momentarily interrupted for the transmission and reception of one static picture image of one frame over the same telephone line. As shown, subscribers A and B are interconnected by a single telephone line L which is connected to a terminal 17a of a transfer circuit 22A including three contacts 14a, 15a and 16a. The operation of transfer circuit 22A is controlled by control circuit 23A which responds to commands from a manual controller 24A which controls transmission of images and from a carrier wave detector circuit 25A which controls reception of images. Contacts 14a, 15a and 16a are connected respectively to a telephone 26A, an image receiver 27A and a modulator 28A in which the image signals from a camera 30A modulate a carrier wave, e.g. 2À5 kc., from an oscillator 29A. The identical components at the terminal of subscriber B are designated with a suffix B. In operation, telephones 26A and 26B are connected to the line L, but when subscriber A operates the manual controller 24A to transmit images to subscriber B the control circuit 23A switches the terminal 17a to contact 16a. The transmitted image signals are detected by the carrier current detector circuit 25B to actuate the control circuit 23B so as to switch the response terminal 17b to the contact 15b and start the image receiver 27B. Similarly, image signals and speech signals may be transmitted alternatively from subscriber B to A. The cameras used in the system are vidicon cameras having low scanning speeds or cameras including photo-electric conversion systems operated by means of mechanical scanning which convert a static picture image of one frame into an image signal having a band compressed by the low speed scanning. The receivers used in the system display the received images as static images and may comprise an electrostatic device, a direct vision storage tube or means which stores the images magnetically at a low speed and repeatedly reproduces them at a high speed on a cathode-ray tube enabling the subscribers to speak to each other while viewing the displayed images. The receiver at each terminal may monitor the signals transmitted from that terminal. In a further embodiment the image transmitting and receiving devices may be connected to the telephone line through magnetic couplings under the control of transfer circuits without making electrical connections to the telephone line.

Title: Improvements in or relating to electric discharge tubes
IPC: H01J19/42
Filed: 1946-06-14
Abstract: 613,556. Thermionic valves. PHILIPS LAMPS, Ltd. June 14, 1946, No. 18032. Convention date, June 15, 1945. [Class 39 (i)] An electron discharge device has contact pins which are sealed through the base, one or more of which serve substantially to support the electrode structure. Such a pin 4, 41, 4<11> is interrupted at 5, and the gap bridged by a metal strip 6 of or plated with copper or silver. This is stated to prevent the contact pin 4 from oxidizing by reducing conduction of heat from the electrode, while not affecting the electrical conductivity. The reduced mechanical strength is compensated for by a U- shaped bracket 7 welded at its mid-point 8 to the part 4<1>, its extremities being fixed to an insulating spacer of the electrode system.

Title: Improvements in and relating to the catalytic synthesis of aliphatic alcohols
IPC: C07C29/152
Filed: 1928-06-22
Abstract: 323,240. Marks, E. C. R., (Du Pont de Nemours Co., E. I.). June 22, 1928. Alcohols other than methanol are synthesized from carbon monoxide and hydrogen in the presence of a methanol catalyst to which an alkali metal compound has been added, the process being operated at a space velocity of the reacting gases which is more than five times the space velocity at which a methanol synthesis employing only the methanol catalyst would reach equilibrium under the same temperature and pressure conditions. The space-time yields for space velocities above the said five-fold space velocity are stated to be greater than would be expected from a consideration of the yields at lower space velocities. According to the examples, (1) a space velocity of at least 40,000 litres of gas per litre of catalyst per hour is used when a gas mixture containing 35 per cent carbon monoxide and 50 per cent hydrogen is passed over a catalyst prepared by the gentle ignition of basic zinc ammonium chromate and mixing potassium chromate therewith, a temperature of 450‹ C. and a pressure of 280 atmospheres being employed; (2) under the same temperature conditions andusing the same gas proportions as before, but under a pressure of 1000 atmospheres and using a zinc chromite catalyst containing potassium sulphate, a space velocity of at least 100,000 litres of gas per litre of catalyst per hour is employed; (3) when passing water gas at a temperature of 475‹ C. and under a pressure of 225 atmospheres over a catalyst prepared by reducing a mixture in equivalent proportions of zinc oxide and potassium chromate, a space velocity of at least 40,000 litres of gas per litre of catalyst per hour is employed.
