Patent DE-2712283-A1 (DE)
Title: Gas actuated planing device ignition system - has spot heating source forming strip of preheated metal on workpiece (SW 25.4.77)
Inventor: SIPEK LADISLAV
IPC: B23K7/06
Filed: 1977-03-21
Abstract: The system ignites a gas planing device acting on a workpiece by heating a set amt. of metal to ignition temperature with the aid of a spot-heating source. The heating source repeats a movement relative to the planing burner with a velocity component equal to the absolute resultant velocity of the workpiece, and forms a strip of pre-heated metal on the surface of the latter, at right angles to the flow direction of the current of planing oxygen. The source can have a velocity component at right angles to this flow direction, and its relative movement can coincide with that of the workpiece to the planing burner.

Title: Imitation bricks mfr., for interior or exterior wall cladding - by sand coating textured plastics on a fleece substrate
Inventor: PEGGEN GEB KENTER GISELA
IPC: E04F13/18
Filed: 1977-03-31
Abstract: The plastics is applied whilst wet and opt. sprinkled with sand. The surface is then irregularly structured, dried, hardened and finally divided in slabs whose size corresponds to that face of a normal-sized brick exposed to view. To impart the irregular superficial appearance the coating is mechanically wrinkled. In addition it may be randomly pigmented. When a base that is relatively easily impregnated by the coating is used then it is advantageous to back the base with a plastics film which is stripped off after the coating has dried and set. The film may be cellulosic.

Title: Automatic sterilisation of water by chlorine or bromine - from containers permitting reaction of acid on salts
Inventor: HAGER KLAUS
IPC: C02F1/76
Filed: 1978-02-22

Title: Linear and nonlinear distortion compensator in hearing-aid - has second microphone to produce oppositely phased signal for adding to input of output amplifier
Inventor: SCHMIDT WOLFGANG
IPC: H04R3/00

Title: Continuous contactless profile measurement of rapidly moving material - using image analyser evaluating optically formed surface markings for comparison with master profile
Inventor: HOEHBERGER HANS-JOERG DIPL PHY
IPC: G01B15/04
Filed: 1978-12-22
Abstract: A device for continuous contactless shape measurement of rolled, drawn and extruded products, e.g. railway tracks, enables accurate profile measurement of material moving rapidly past it. Optical markings in the form of straight continuous or interrupted narrow dark-bright-dark zone interfaces are formed on the object surface by inclined light beams. The position, direction, and curvature of the markings are profile dependent. Their images are formed on an image analyser producing profile or shape representative signals. The signals are evaluated to determine the actual profile or its deviation from a master profile. Infrared, or ultraviolet light, X-ray, or ultrasonic systems may be used. If monochromatic or polarised electromagnetic waves are used the detection system is sensitive only to the frequency or polarisation employed.
