Patent DE-3840863-A1 (DE)
Title: Internal-shaft rotary-piston compressor
Inventor: LANG SIEGFRIED DIPL ING
IPC: F04C18/10
Filed: 1988-12-03
Abstract: An internal-shaft rotary-piston compressor contains an inner rotor (18) which is arranged eccentrically with respect to an outer rotor (20, 22) and meshes therewith. A rotary movement initiated at one rotor is transmitted to the other rotor by means of rolling elements (30) which separate chambers from one another, whose volume is changeable during rotation. This rotary-piston compressor is to be improved, with little cost in terms of construction, in such a way that, while the material can be freely chosen, reliable sealing of the chambers is ensured. It is proposed for the rolling elements (30) each to be supported on one side by means of a pin (stud) (32) in the outer rotor (20, 22), which in turn is supported on one side in the casing (2) by means of a rolling-element bearing (24). Said rolling-element bearing (24) is arranged in a radial plane which is at a distance from the inner rotor (18), and/or it has a smaller external diameter than the outer rotor (20). <IMAGE>

IPC: A61F7/00
Filed: 1989-01-26
Abstract: A bag-shaped cooling device for filling with a liquid coolant is characterised in that it is made of a liquid-tight, vapour-impermeable material at least on one side, namely the side serving for cooling. On this material is superimposed a hydrophilic, water-absorbing material layer and thereupon a hydrophobic, water-conducting material layer. All these materials are bielastic materials and the liquid-tight, vapour-impermeable material changes the stress-strain values of its starting elasticity by at most 20% on cooling to -18@C.

Title: Read-write unit for data cards - has slide=in carriage with guide system to bring card against contacts
Inventor: MACQUAIRE PATRICE
IPC: G06K7/00
Filed: 1989-05-23
Abstract: The read/write unit is for intelligent data cards that have integrated circuit chips. The card (5) is loaded onto a carriage (2) that is inserted into a housing (1) by applying finger pressure to the push-button. The carriage moves on guides within the housing until a switch at the rear of the housing is contacted (18). As the card moves to the inserted position a contact carrier (8) with an angled top surface is moved against a rail (8) and in doing so is forced to move downwards. This brings the read/write contacts (9,10) against the surface of the card.  Activation of the contact at the rear connects power to the head. ADVANTAGE - Simplifies operation with reduced chance of manipulation.

Title: Appts. to prevent flue gas formation in metallurgical process
Inventor: MOHNKERN HORSTMAR DIPL ING
IPC: C21B7/14
Filed: 1989-09-04
Abstract: Device for avoiding the formation of flue gases in metallurgical processes and when transporting molten metal from metallurgical vessels, esp. blast furnaces (10) to casting vessels has esp. discharge channels (15-16) which take the molten metal from the furnace's casting outlet, covered by hoods (22-24) so that minimal space exists above the molten metal. The transfer stations (17-19) at which the metal transfers esp. from the transporter and discharge channels into the casting vessel, and the outflow openings are shielded to render them gas tight. Inert gas flushes through this transfer point and the space in the covered channels. An inert gas mantel, circular in cross-section, protects the molten stream as it flows from the outlet into the casting vessel, and is generated at a pressure of pref. 1.5 bar. An inert gas pressure of pref. between 10 and 100 Pa above the external pressure is maintained in the furnace or transport unit, or both esp. over the transport and discharge channels, also at the transition pt. and in the interior of the casting vessel.  The inert gas also serves to cool the covers and shielding mechanisms and comprises nitrogen or similar gas, whose free oxygen component has been consumed by burning in a combustion chamber and which is finally cooled.
