Title: Improvements in and relating to filaments and fibres
IPC: D01D5/24
Filed: 1956-01-09
Abstract: <PICT:0818215/IV (a)/1> <PICT:0818215/IV (a)/2> <PICT:0818215/IV (a)/3> <PICT:0818215/IV (a)/4> Synthetic filaments having an annular crosssection are produced by extruding a filamentforming solution through a spinneret having extrusion orifices, each having the shape of a sector of a circle subtended by an angle of approximately 210 degrees, into a dry-spinning cabinet, and drafting the filaments while drying them.  The filament-forming solution may be a solution of a cellulose organic acid ester, e.g. cellulose acetate in acetone. As shown, filaments 25 extended through orifices 14 of spinneret 13 initially have C-shaped cross-sections, but controlled drafting and drying cause the arms of the C to unite, as shown in Fig. 4. The filaments may be drafted at a draft ratio above 0.6, the latter being defined as the ratio of the linear velocity of wind-up to the linear velocity of extrusion of the filaments. Preferably the filaments are dried between 60 DEG  and 90 DEG  C. Comparative examples are given. U.S.A. Specifications 1,695,455, 1,773,969, 2,000,047, 2,000,048 and 2,373,892 are referred to.

Patent GB-739086-A (GB)
Title: Production of melamine
Filed: 1953-01-09
Abstract: Melamine is manufactured by heating urea in a stream of anhydrous gas consisting essentially of ammonia at 130-150 DEG  C. (preferably 135-140 DEG  C.) until the evolution of water has substantially ceased, and thereafter raising the temperature to 200-300 DEG  C. (preferably 220-280 DEG  C.) while continuing to pass anhydrous gas consisting essentially of ammonia.  The melamine formed is swept out in the form of vapour and may be recovered by cooling the ammonia stream or conducting it against a cool surface.  The ammonia, which under some conditions is desirably diluted with up to 20 per cent by volume of an anhydrous inert gas such as nitrogen, may be dried and recirculated.  The temperatures are best regulated by suitable preheating of the ammonia.  The process is preferably effected at atmospheric pressure, though reduced or increased pressure may be used, e.g. the first stage may be carried out at reduced pressures and the second at pressures up to 2500 p.s.i.g.  The process may be made continuous by passing urea on a continuous belt in countercurrent to ammonia at the lower temperature and then in concurrent direction with ammonia at a higher temperature, the latter travelling faster than the belt.  Alternatively two or more reactors may be employed in parallel, one working at the lower and a second at the higher temperature.  In an example, the first stage is effected at 140 DEG  C. and the second at 280 DEG  C., and 70-100 mols. of ammonia are used per mol. of urea.  Specification 641,643 is referred to.

Title: Methods of and apparatus for intercommunication
IPC: H04J3/04
Filed: 1929-01-08
Abstract: 303,800. Loeb, J., and Compagnie des Lampes. Jan. 9, 1928, [Convention date]. Vacuum tubes.-A. thermionic valve, particularly for use as a distributor in a system for multiplexing telephone conversations or for wireless conversations on a single carrier, has a cathode, a grid, an anode, and means such as conductors for producing a rotating field, so as to direct the electron stream towards and away from the anode at predetermined intervals. As shown, the conductors 2, 3, 4, supplied with 3- phase current, consist of tungsten rods of much larger diameter than the filament cathode 1, and the grid 5 and anode 6 are in the form of arcs of circles symmetrical in relation to the plane containing the filament and one conductor 2. Two screens 7, 8 may be provided. The leads for the conductors may be passed through the opposite end of the valve from that at which the other leads are connected. In one example each station has three valves, supplied with 3- phase current, one valve being for transmission, one for reception, and one for synchronization. In order to increase the number of conversations, the valves may be modified, as by arranging the grid and anode outside the conductors, or by displacing the grids and anodes; or the valves may all be of the same construction and the sets of polyphase voltages displaced by a predetermined angle. For example six sets of 3- phase voltages differing in phase by 60‹ may be arranged for the rotating fields of six distributor valves at each station so as to provide for five conversations, one valve at each station being used for regulation. Specification 289,102 is referred to.

Title: Progressive scan television receiver with adaptive memory addressing
Inventor: MAZE KENNETH WAYNE
IPC: H04N5/44
Filed: 1993-08-26
Abstract: A video input signal (S2) is stored in a memory (24) and read twice during a line-interval to provide a processed video output signal having a doubled line rate (2FH) for display on a display device (18) having a doubled horizontal sweep rate (2FH) thereby providing a progressively scanned image having reduced visibility of line structure. The last address written in memory is used to control the starting time of the second memory read operation. This reduces the tendency of visible artifacts to occur in cases where the video input signal is "non-standard" in the sense that the ratio of the color subcarrier frequency with respect to the line rate is such that there may not be a fixed number of color subcarrier cycles per line.

Title: Operation control circuit for freezing air conditioners
Inventor: HOSOE YOSHIHISA
IPC: F25B49/00
Filed: 1978-01-06
Abstract: PURPOSE: When running condition has come close to the level where a safety device works, to enable operation to be continued as long as possible by lowering the high temperature and pressure at which said safety device works to the normal values thereof.  
     CONSTITUTION: When high pressure said for example has risen close to the set value for working a pressure switch 4 in room cooling operation, said pressure switch 20 works to open a contact. Then, an auxiliary relay 24 is de-energized, a contact 24a is connected to a high-speed terminal 26b, the high-and low-speed variable type motor 26 of a condenser blower is changed over to high-speed revolution. Therefore, the air flow to a condenser increases, and condesation capacity increases to lower high-pressure side pressure. Thereby, said pressure switch 4 is prevented from working so that freezing  cycle operation can be continued in normal condition.
