Title: Electron beam surface hardening - with fast moving workpiece relative to stationary or oscillating electron beam
IPC: C21D1/09
Filed: 1970-07-27
Abstract: Fast and uniform hardening of surfaces such as the running tracks of ball races can be achieved by rotating the race fast relative to an electron beam focused on its surface. If the beam is stationary, it is shaped to impinge on the track along an axial line or ellipse. If the base is a narrow pencil beam, it is oscillated by a deflector system at right angles to the direction of motion.

Patent DE-2041127-A1 (DE)
Title: High-speed burners - use excess air to equalise temp throughout charge
Inventor: KNAAK RUEDIGER DIPL-ING DR
IPC: F27D7/00
Filed: 1970-08-19
Abstract: When using high-speed burners, the time during which the burners are "on" is sometimes so short that the circulating hot gases do not have time to carry the heat equally to all parts of the charge. This situation is improved by reducing the temperature of the hot gases by admitting an excess of air up to a ratio of about 1.2. When the burner is switched "on", it works with excess air for a certain time before being switched back to the stoichiometric proportion. Then, when the burner is switched "off", it switches instead to working with excess air. It is thus possible to ensure even temperature for long periods, even when working with a partly loaded furnace.
Patent DE-2055556-A1 (DE)
Title: Heat transfer film - with a dry upper surface and self-adhesive lower surface

Patent DE-2313522-A1 (DE)
Title: Material testing - using rotating lens drum angled across the line of the fabric
Inventor: PURLL DAVID JOHN
IPC: G01N21/89
Filed: 1973-03-19
Abstract: The angle of the rotating drum, carrying a number of lenses, is such that a test field is developed, oriented at about 45 degrees to the direction of fabric flow. Light passing through the fabric is reflected from the lenses to a photo detector which develops an electric signal. Should a fault appear in the fabric, then the reflected light is changed giving a variation in the generated electric signal to indicate that a fault exists. The design allows faults to be detected in both the warp and weft lines of the test fabric.
Patent DE-2318599-A1 (DE)
Title: Aluminium electrolysis furnace with improved current-distribution - cathode cont. insulating blocks reduces erosion of furnace walls
Inventor: WITTNER HUBERT DR
IPC: C25C3/08
Filed: 1973-04-13
Abstract: The furnace contains anodes, plus a cathode made of carbon blocks with the same electrical conductivity, and the surface of the cathode facing the anodes is partly covered with a rammed mass of electrically non-conducting matl. e.g. SiC, magnesite or corundum, i.e. with a similar coefft. of thermal expansion to the cathode. When a furnace is fed with alumina along the central axis between the electrodes, the hottest zone is at the outside and the result is erosion of the furnace walls. By inserting electrically insulating blocks at the sides of the cathode, the current is deflected so that it flows in the centre of the furnace and there is a favourable temp. gradient, i.e. the temp. drops towards the walls. As a result, a solidified layer of electrolyte is formed at the sides which prevents erosion of the furnace walls. If the alumina is charged into the furnace from the sides, the position of the insulating blocks can be altered so that a favourable temp. distribution is still obtd.

Title: Gas operated extrusion gun - for extruding adhesives, putties or sealants has prepacked cylinder pierced when nozzle is fitted
IPC: B65D83/00
Filed: 1973-10-03
Abstract: The gun consists of a cylindrical container fitted with a discharge nozzle. The container holds the product and has a piston at the lower end which forces the contents of the cylinder through the discharge nozzle. The piston is forced to move by gas pressure in a gas container locked inside the cylinder. The gas is released by opening a valve. The entire cylinder is normally sealed and the seal is pierced by a knife on the nozzle assembly when the cylinder is used initially. The gas pressure is sufficient to discharge all the contents.

Title: Anhydrous sodium dithionite from sulphur dioxide and sodium formate - in a medium contg. water, alcohol and pyrrolidone
Inventor: VOELKL ERFRIED DIPL CHEM DR
IPC: C01B17/66
Filed: 1974-03-29
Abstract: Anhydrous Na dithionite is prepd. by reacting SO2 with Na formate in a solvent comprising a mixt. of an aq. alcohol and a pyrrolidone of formula (I) (where R is 1-6C alkyl or aryl), with the proviso that after all the reactants have been added, the alcohol + (I) make up 65-90 (pref. 70-85) wt. % of the total solvent and the concn. of (I) in the alcohol + (I) mixt. is 10-60 (pref. 25-40) wt. %.

Title: A.F. signals dynamic compression and expansion - involves extraction of root from signal for compression, and elevation to power for expansion
Inventor: DAVIES JACK L
IPC: H03G7/00
Filed: 1974-04-09
Abstract: Both operations are performed as functions of time; before the root extraction with an even index, the absolute value of the signal is determined, and after root extraction the compressed a.f. signal is obtained from the root extraction result by inversion of alternate half-periods; expansion of the original a.f. signal recovery is carried out by elevating to an even power of the a.f. signal absolute value, and then inverting alternate half-periods; typically the dynamic compression as a function of time is done with the index 2. The method gives exact reproduction of signals with considerable compression of dynamic range over the transmission link.
