Title: Single electron gun colour CRT - has screen with phosphor strips whose number corresponds to lines of TV standard
Inventor: GUSTAV LOTHAR DIPL ING
IPC: H01J31/20
Filed: 1974-01-11
Abstract: The image screen of the single electron gun colour cathode-ray tube has a phosphor strip structure, in which the number of parallel, mutually electrically insulated strips is in agreement to the number of lines of the applied television standard.

Title: Metal casting with vacuum in mould chamber - to prevent formation of bubbles beneath surface of cast article
Inventor: HOELTER HEINZ
IPC: B22D18/06

This is achieved by using a porous mould, and inserting it in a vacuum vessel so that migration of gas does not incur into the casting, but gas is sucked out through the mould. Alternatively the mould may be provided with pipe-like deaerating means to which is attached a vacuum-generating device on the outside.
Patent DE-2443489-A1 (DE)
Title: Wide band wood plank polishing machine - has automatic retraction at power failure
IPC: B24B21/04
Filed: 1974-09-11
Abstract: The machine has at least one endless polishing belt, running over a roller which is moved towards the plank to be polished. Each belt is motor driven and kept tight by a tensioning roller. The polishing roller is pressed from above against the plank, by a pneumatic actuator. The position of the polishing and support rollers can be controlled by an electrically operated valve as in 2434210. The actuators for the polishing and support rollers are double acting. When the power which drives the polishing belt fails, the electrically operated valve automatically reverses the air flow to the actuators, so that the rollers are lifted from the plank.

Title: Counter with magnetic reset to zero - comprises permanent magnet rings with increased width at required position
Inventor: BAERMANN MAX
IPC: G06M3/02
Filed: 1975-01-25
Abstract: Recorders or counters with a reset to zero facility are used to control machines and industrial processes. The figures appearing in windows of a scale can be manually altered and the signals reduce the figures until zeros are altered and the signals reduce the figures until zeros are reached to complete a cycle. Difficulties particularly with low numbers are overcome by using magnetic techniques. A counter comprises a number of magnetic rings readily manufactured from permanent magnetic particles. The rings have magnetic polarity so that in the required position opposite poles are facing. These poles extend around the periphery for approximately 180 degrees with only a small space between adjacent rings, the width of the pole is greater at the required position.

Title: Measurement of sound velocity in a medium - is by currents induced by mechanical pressure on pre-magnetised film as sound pulse passes
Inventor: RUNGE RUEDIGER
IPC: G01H3/12
Filed: 1975-07-03
Abstract: The instrument is for measuring the velocity of sound in a medium, and enables the result to be displayed digitally. A straight, relatively stiff, electric conductor (2) is surrounded by a thin elastic coating (3), coated on its outer surface with a magnetic film (3'), in which a magnetic structure representing a linear scale has been pre-recorded. The assembly is pressed against a flat acoustic conductor (4) in which the measurement is to be made, or immersed in a liquid or gaseous medium, and an acoustic pulse is triggered from a source (5). The resulting mechanical movement will affect the magnetic film, and induce signals in the conductor (2). The induced currents will have a frequency determined by the division of the prerecorded magnetic scale and the velocity of propagation of the sound pulse in the medium.

Title: Aluminium prepn. from aluminium halides by reaction with sulphur - by reaction with sulphur or from alumina after halogenating with sulphuryl halides
Inventor: OTHMER DONALD F
IPC: C22B5/08
Filed: 1975-07-19
Abstract: Al is produced by reacting an Al halide with elementary S to form Al and an S halide. Al is then sepd. from S halide and from an excess of original reactants. The S halide formed may be used as halogenating agent for halogenating Al2O3-contg. material, either to form the Al monohalide at >1500 degrees C or at lower temps., to form Al trihalide and S. These reaction products can then be converted to Al and S halide. Process is economical. Reagents are not consumed, but recycled. Energy requirements are small. Typically, AlCl3 can react with S in a spray - or flash-condenser to produce Al and S2Cl2. Reaction may take place in a liquid phase of AlCl3, kept at a temp. and press above its triple point, or in a liquid phase contg. AlCl3 and 5-95% chloride of >=1 alkali metal.
