Title: Low-melting dental ceramic of high thermal expansion and corrosion resistance
IPC: A61K6/06
Filed: 1989-04-05
Abstract: Dental ceramics with high thermal expansion as are used to produce metal/ceramic and full ceramic tooth replacements in the sinter process are normally processed (sintered, fired) at temperatures of 950@C +/- 30@C. It has been thought impossible to date to reduce this processing temperature considerably without at the same time losing thermal expansion and/or corrosion resistance or without using biologically unacceptable constituents such as, for example, lead oxide. With the dental ceramic according to the invention it is possible, while maintaining the usual values for thermal expansion, corrosion resistance and biological acceptability, to advance into a region of processing temperature of 725@C +/- 25@C. This opens up completely new uses for such dental ceramics and for their combinations with known normal-melting dental ceramics.

Filed: 1989-04-13
Abstract: 2.1 In known digital communication exchanges, computers are used for supporting the control device for adding additional features. For this purpose, the computer is directly connected to the control device. This also requires intervention in the control sequence of the control device. The object consists of providing a communication exchange with additional functions without this requiring intervention in the control sequence. 
<??>2.2 The computers with the additional function are connected to the digital communication exchange like normal terminals, data being exchanged between these and the control device (ST) via an auxiliary control device (HS). The auxiliary control device (HS) in this case monitors and controls the data exchange and the data calibration if data have been changed in a computer (PC) or in the subscriber data memory in the memory (SP) of the communication exchange. 
<??>2.3 The communication exchange according to the invention exhibits a database distributed to several computers and the subscriber data memory, which database can be used not only as "telephone book" or network database but also for personal time acquisition, in ordering, in a hospital or also as an emergency call system.

Title: Leakage path for charge carriers - on cover panels off solar generators joined by conductive adhesive
Inventor: KOCH JUERGEN DIPL PHYS
IPC: H01L31/05
Filed: 1989-04-29
Abstract: A fitment on solar generators prevents static charges from accumulating between conductive surfaces and a carrier structure. The covering glass panes have on top and along the faces a conductive lining. Between these faces and the connectors of the solar cells, a non-transparent conductive adhesive joins these components conductively. A connector (1) which is partly covered together with the solar cell (2) by a cover glass pane (6) has a bow (3) to absorb thermally induced movements. Top and faces (5) of this pane (6) are coated with indium-tin oxide (11). The gap between the faces (5) and the tab (4) of the connector is filled with a conductive substance such as an adhesive (7) of conductive elastic silicone rubber to act as a leakage path for charge carriers. ADVANTAGE - This dissipates static charge carriers from the surface of the cover panes without changing the resistance figures for electrically connected components.

Title: Attaching of cams to hollow camshaft - by diametral expansion of camshaft by hydraulic pressure and axial load
Inventor: PODHORSKY MIROSLAN DR
IPC: B21D53/84
Filed: 1989-12-18
Abstract: The invention concerns a method of attaching components to a hollow shaft and in partic. to attaching cams (T1 to T4) to a hollow camshaft (H).

Title: Hybrid process intensifying wet gas cleaning - with integrated heat recovery for brown coal fired furnaces
Inventor: MUELLER HORST
IPC: F23J15/00
