Patent DE-2753557-A1 (DE)
Inventor: AEBI WALTER
IPC: B41L19/00
Filed: 1977-12-01
Abstract: The printer has a base plate (1) having a soft support surface (7) for the identity card, for example a cheque card, and a contact-pressure plate (2) which is articulated to this base plate and has a cutout (16) in which a hard pressure roller (20) is displaceably arranged. Using a handle, the roller can be pressed along a guide (19) against a document inserted into the printer and rolled to and fro. The choice of the soft pad for the identity card and the hard pressure roller causes the relative surface pressure on the articles to be printed to be increased, as a result of which the printed information is more legible. Any unevennesses in the level of the article are compensated for by the soft pad for the identity card. <IMAGE>
Patent DE-2802788-A1 (DE)
Title: Switching network circuit breaker operation - storing switch states before supply drop=out and closing switches sequentially when supply returns
Inventor: BAYER HELMUT
IPC: H02H3/06
Filed: 1978-01-23
Abstract: The switching network closes circuit breakers when the voltage supply returns after being disconnected. A tore retains the states, i.e. open or closed, of the circuit breakers when the supply voltage is present. When the voltage fails, all circuit breakers are automatically opened. When the supply returns the circuit breakers are closed one after another. The advantage lies in needing no battery to provide an auxiliary supply.

Title: Coating for internal holes in gas turbine blades - consists of aluminide layer with no diffusion layer between this and substrate
Inventor: FITZER ERICH PROF DR
IPC: F01D5/28
Filed: 1978-02-09
Abstract: Before the blade is put into service, the coating consists of an aluminide layer(a), and no diffusion layer exists between layer(a) and the surface of holes in the blade. In the pref. coating process, AlCl3 is reacted with Al or its alloys at over 900 degrees C. to produce a subhalide AlClx; the subhalide is then employed a below 900 degrees C., and esp. at 700-850 degrees C to deposit Al in the holes in the blade, esp. in a current of H2 and in a descending temp. gradient. The holes forming coolant channels in the blades can be coated with Al which has exceptionally good adhesion and without using an intermediate diffusion layer. The Al exhibits much better oxidn. and corrosion resistance in service than conventional coatings. It is possible that a diffusion layer froms at the operating temp. of the turbine, but this does not affect the superior performance obtd. by the invention.

Title: Electrical component insulating device - with dipping disc transferring casting resin to components between moving tapes
Inventor: STEGMEYER ALFRED AUGUST DIPL I
IPC: H01G9/08
Filed: 1978-10-17
Abstract: Electric components of cylindricals shape with axial connecting wires are coated with a viscous insulating material (casting resin) by attaching the components with the ends of the conncting wires to two parallel tapes which are moved in the horizontal direction. A vertical disc with a thickness which slightly exceeds the length of the components dips into a container filled with an insulating cpd. and contacts the components at the top of its rim. The disc revolves at the same speed as the components but an oscillation motion relative to the components is superimposed to the rotary motion. A scraper blade at the exit from the insulating cpd. keeps the layer transferred to the desired thickness which is slightly more than the gap between disc and elements at the point of contact. Perforations in the tapes assist their steady movement. Such a device is suitable for mass prodn. and provides an insulation at low cost and with time savings.
