Title: Continuous band press for chipboards - comprising smooth pressure belt members having thermal insulation pressure cushions and low-friction faces
Inventor: FOERCH FRIEDHELM DIPL ING
IPC: B30B5/06
Filed: 1977-02-09
Abstract: A continuous press, for prodn. of chipboards, hardboards, plywood etc., has heated endless belts to transmit applied pressure and to draw the material through, plus outer heated flexible bands under tension which pass round drive drums/wheels to guide drums/wheels and the pressure area. These latter bands have an adjustable gap between the pressure table and the pressure platen, whose surfaces are smooth and have thermally insulating pressure cushions plus steel sheet to cover the cushions; the individual heating units of the flexible bands also have an insulating low-friction covering on their faces towards the stationary pressure areas. The thermal insulation eliminates thermal expansion stresses in the pressure table and pressure platen, the driving drums are not contaminated with low-friction materials, the low-friction coverings can be of any desired thickness for long life, the heat produced is held by the operating parts.

Title: IC engine ignition coil - has thermoplastics or metal alloy solder fuses to open inner chamber if overheating occurs
Inventor: WOERZ PAUL
IPC: H01F27/40
Filed: 1977-07-26
Abstract: The ignition coil of an electronically controlled IC engine ignition system has a fuse to avoid overheating which could cause a high internal pressure in the sealed coil case and lead to an explosion. The fuse opens the inner space of the coil. The primary terminals (13) are drilled (19) and the LT lead (21) soldered to the outside of the terminal with a solder (22) having a low melting point, esp. a metal alloy. A thermoplastic fuse material may also be used, esp. one with a crystalline structure. Any dangerous overheating thus fuses the solder and opens the coil chamber to atmosphere. A similar plug (25) may be incorporated in the HT connection (17).

Title: Promotion of epitaxial film growth - by forming stepped defect pattern on substrate surface
Inventor: SMITH HENRY I
IPC: C30B25/18
Filed: 1978-04-22

Title: Optical ray railway track position measuring - involves production of reference axis beam parallel to track outside vehicle contour
Inventor: BUDDE ULRICH DIPL ING
IPC: E01B35/00
Filed: 1978-07-20
Abstract: Staged metering of both rails (1, 2) of a track in relation to a reference axis is provided by a beam of light (5).

Title: Electroplating current reversal control - using electronic components concentrated on plug-in module
Inventor: HUEBEL EGON
IPC: C25D21/12
Filed: 1978-07-18
Abstract: All components required for these control operations are electronic units which are concentrated on a plug-in module on the same flat control panel as the rectifier controller. This saves the purchase and assembly of separate control apparatus and the wiring between the components. The control cubicle can be designed much smaller. The front panel of the control cubicle contains, apart from the potentiometers and pilot lamps for the polarity reversal, a trimmer to adjust the time for which the control remains inactive at the start. A second timmer sets the time for which the workpieces in the electroplating cell retain the anodic polarity, and a third trimmer sets the cathodic polarity duration.
