Patent DE-2751263-A1 (DE)
Title: Baking plate set for crisp pastry - has bosses on surface and notches on sides for steam escape control
Inventor: HOEHN KARL
IPC: A21B3/13
Filed: 1977-11-14
Abstract: A set of baking plates for pastry such as waffles and crackers consists of an upper and a lower plate each with two sides. The baking surfaces have raised bosses in an irregular pattern. The sides have many tapering notches, starting at their upper edges. The bosses prevent too fast an escape of the water vapour. The side notches allow the steam to be released. The result is a more uniformly baked pastry of crisp consistency.

Title: Domestic oven vapour eliminator - is in form of after burner with spiral heating coil under fine mesh grid inside cup shaped housing
Inventor: SCHMIDT ULRICH DIPL ING
IPC: F24C15/20
Filed: 1978-02-23
Abstract: The steam, vapour and smoke eliminator for a domestic oven, which acts as an after burner, has a cap shaped body (1) which is located in the path of the steam, with a helical heating coil (2) inside. Inside the body, and above the coil is a fine mesh grid (3) of chromium nickel steel wire. This mesh is heated by the coil to a temperature of about 700 deg.C to a red glow. The steam, vapours etc. are eliminated as they pass through the mesh of the grid, thus eliminating smells and dirt from the kitchen.

Title: Base for laying wall, floor or ceiling panels - comprises mortar sprayed onto surface, pref. with woven material rolled in
Inventor: LUX HERBERT
IPC: E04F13/08
Filed: 1978-02-24
Abstract: The process is for laying panels as cladding on walls, floors or ceilings, and for making tiled partition walls. Instead of applying mortar consolidation in the usual thick bed form, or as a thin bed, mortar is sprayed onto the surface to be clad, in the required quantity; after skimming clean, it forms a closed, correctly aligned flat surface. A patterned weave can be rolled in diagonally and crossways, to provide an ideal rough surface, and even thick panels which are not always smooth can be embedded in it.
Patent DE-2808605-A1 (DE)
Inventor: RAISER INGRID
IPC: B29C57/00
Filed: 1978-02-28
Abstract: In the process, a plastic material (50) mixed with reinforcing fibre shreds or flaky reinforcing particles is applied in the flowable state to the cleaned interior wall of the steel tank. The essentially non-shrinking plastic material, after curing, forms together with the steel wall a wall of composite material. It is thereby possible in a cost-saving manner to produce a renovated steel tank which has a higher strength than hitherto and in which rusting on the interior surface of the steel wall is prevented. Before and during the application, the relative air humidity in the tank (2) is reduced and kept low by means of a device (4). The plastic material mixed with the reinforcing particles is conveyed from a storage and pressure conveying device (8) to the application apparatus (10). A propellent-air device (12) serves for generating heated propellent air. <IMAGE>

Title: Control for automatic transmission - has manual override and kickdown facility, with interlock prevent starting in wrong setting
Inventor: FRANZ KASPAR ING GRAD
IPC: B60W30/18
Filed: 1978-07-01
Abstract: The transmission provides manual or automatic gear change as selected, with safety interlocks preventing damage due to faulty gearchange operations. The park setting cannot be selected while travelling and a change of mode only occurs if the dynamic conditions allow. The system provides an interlock which opens the starter circuit if the vehicle is in gear, or in the park setting. A kickdown facility is included for optimum performance. The mode of gearchange can be selected while travelling, with automatic compensation to provide the correct dynamic conditions.

Patent DE-2834873-A1 (DE)
Title: Piercing of thin materials e.g. plastic sheet, leather and metal - by needles rotating at high speed for optimum sliding friction
Inventor: KAMM WILLIBALD FRITZ GUSTAV DI
IPC: B26F1/16
Filed: 1978-08-09
Abstract: Perforations in materials of medium strength, such as leather, thin steel metal, textiles, plastic foils and sheets, cardboard, etc., are produced by needles which are rotated at high speed during the piercing operation. The resultant of rotary and piercing velocity is chosen to equal the velocity at which the sliding friction between needle and material becomes a minimum. This optimises the piercing conditions and results in a much longer service life of the delicate needles.

Title: Circuit for resistance measurement - produces digital output voltage across resistor and across reference and is used in dual slope converter
Inventor: KOSLAR MANFRED DIPL ING
IPC: H03M1/00

Title: Appts. to avoid electrode fracture in arc furnaces - comprises monitor of hydraulic pressure to lifting cylinder to check if obstruction is encountered when lowering electrode
Inventor: KOUDELKA MIROSLAV DIPL ING
IPC: F27D11/10
Filed: 1979-07-27
Abstract: Electrode fracture in electric arc furnaces due to contact with non-conducting material is avoided by a sensor in the hydraulic circuitry. The electrodes are raised and lowered by a hydraulic cylinder. The oil line to the cylinder has a pressure sensor in it which is connected to a relay switch. As the electrode descends the pressure in the line declines. If the electrode hits an obstruction, the pressure drops to zero. A zero pressure signal before the electrodes reaches the end of its stroke causes the relay to reverse and raise the electrode again. For use on electric arc furnaces. Prevents premature wear and damage to C electrodes due to fracture on non-conducting solid material in the furnace.

Title: Screw locking system for electrical applications - has three successive threads deformed by flattening crests to lock in tapped hole
Inventor: WEBER HARALD
IPC: F16B39/30
Filed: 1980-03-27
Abstract: The locking system for a screw is partic. suitable for electrical applications where the screw carries a locking washer held against an upper surface, and where the threads lower down screw into a tapped hole in a plate. A set of e.g. three successive threads, is deformed over a limited region so that force must be used to turn the screw when these threads enter the tapped hole. These threads are located above a threaded section (A) at the bottom of the screw. This deformation consists in flattening a small part (9) of the crests of the threads over a region (B) above this bottom section (A). The depth of thread of the deformation region is about five percent of the full thread diameter. The three deformations can be equally spaced around the screw.
