Patent DE-4201626-A1 (DE)
Inventor: GEHRING PETER
IPC: F16J15/02
Filed: 1992-01-22
Abstract: A sealing device (1) has a sealing chamber (4) which is situated in a part (5) to be sealed off, accommodates the sealing ring (2) and is bounded on its side remote from the thread (3a) by a pinching or cutting edge (8) so that, when the thread (3) of the two parts (5 and 7) to be sealed off is tightened sealing material (9) displaced by the increasing pressure in the sealing chamber (4) emerges radially outwards at the sealing edge (8) and is sheared off, i.e. the sealing chamber is completely filled and the sealing material is put under pressure. To ensure that the resistance to the tightening of the thread (3) between the two parts (5 and 7) to be sealed off does not become too large during this process, leaving a gap (11) between the cutting edge (8) and the opposing surface or end face of the other part (7) under certain circumstances, through which gap the material under pressure in the sealing chamber (4) might creep out over the years, the sealing chamber (4) extends as far as a bottom (12) arranged radially below the core diameter of the thread (3a) of the part (5) in which it is formed and extends axially at least to below the first turn of the other part (7) in the screwed-up end position of the latter and between the first thread turn of the other part (7) and the bottom (12) of the sealing chamber (4) there is a gap (13) for the passage of sealing compound into an interspace (14) situated behind the said gap in the axial direction, the gap being of a width such that the sealing material yields through this gap (13) if there is an excessive increase in the pressure in the sealing chamber (4), allowing the shearing off of sealing material (9) displaced outwards radially through the gap (11) to be accomplished with a reasonable force or reasonable tightening torque and the gap (11) to be completely closed. On the other hand, the gap (13) is sufficiently narrow to ensure that it allows sealing material through only under this severe loading associated with shearing off or pinching off, and the interspace (14) is sufficiently small to ensure that it is likewise substantially or completely filled during this operation. <IMAGE>

Patent DE-4234728-A1 (DE)
Inventor: BARTHOLMES PETER PROF DR
IPC: G01N30/96
Filed: 1992-10-15
Abstract: The invention pertains to a process for extracting and buffering and/or concentrating dissolved macromolecules of a macromolecular mixture using a liquid chromatography apparatus, wherein buffer solutions that promote the separation process are added to the macromolecular mixture to be separated prior to its entering into the liquid chromatography apparatus or during the separation process in the liquid chromatography apparatus, said buffer solutions then being entirely or partially withdrawn and/or exchanged after the separation for purposes of concentrating or purifying the kind of molecules extracted. To be able to carry out such a process of buffering and/or concentrating more quickly and continuously with less outlay for equipment, the invention proposes that the buffer solution be withdrawn and/or exchanged by means of countercurrent dialysis, which is carried out continuously with the eluate of the liquid chromatography apparatus. The countercurrent dialysis proposed as per the invention makes it possible to supply the eluate with specific low-molecular substrates for the enzymatic detection.

Title: Polyimide with special bonding properties to metal, esp. e.g. gold - prepd. by vapour deposition of pyromellitic dianhydride and di:amino-di:phenyl di:sulphide on a metal substrate, followed by imidisation
Inventor: GRUNZE MICHAEL PROF DR
IPC: C23C14/20
Filed: 1992-12-22
Abstract: Polyimide of formula (I) is new; n = 30-35. USE/ADVANTAGE - The invention provides a new polyimide with the advantages of other polyimides, but which also undergoes defined coordinate bonding with metal substrates with cleavage of the S-S bond, resulting in very good adhesion to metals such as Au, Ag, Fe etc. without using an additional coupling agent, as required e.g. for electronics applications. In an example, a clean gold substrate was immersed for 10 hrs. in a 1-mM soln. of DAPS in ethanol, then rinsed under nitrogen with ethanol; the coated substrate was placed in a vacuum chamber and coated with PMDA and 4,4'-oxydianiline (ODA) by vapour deposition from 2 Knudsen cells, and the system was then imidised by heating at 250 deg. C for several hrs. The PMDA/ODA polyimide film, which does not normally react with gold, was coordinatively bonded to the surface via the DAPS mols.

Title: Controller for actuation of occupant restraint in vehicle - takes emergency action when integral of measured deceleration and instantaneous energy calculation identify type of impact.
Inventor: MAZUR JOSEPH F
IPC: B60R21/01
Filed: 1993-01-08
Abstract: An accelerometer (24) or vibration transducer and an amplifier (26) produce an oscillatory signal with a characteristic which denotes the state of impact. A microprocessor (34) monitors this signal at different times and establishes an instantaneous RMS impact energy and a road speed integral for comparison with respective threshold values. The restraint is activated (44) by an FET switch (42) driven by a monostable (40) when the speed integral exceeds its threshold with a given interval after the threshold of instantaneous impact energy is exceeded. ADVANTAGE - Can distinguish between different deg. of impact so that, e.g. an air bag is inflated only when necessary.
Patent DE-4307732-A1 (DE)
Title: Temperature-control device for rotary bodies in printing units
Inventor: KURZ HANS-JOACHIM
IPC: B41F13/22
Filed: 1993-03-11
Abstract: The temperature-control device comprises a blower device (8) with an internal air recirculation loop for recirculating cold air which was deflected by the rotary body (6) to be cooled. A cold-air generator (12) is arranged externally from the blower device (8) and is connected thereto in terms of flow via a cold-air feedline. Energy for generating cold air is thus saved and the cold-air feedlines can have a smaller cross-section since only a reduced quantity of cold air still has to be supplied. <IMAGE>

Title: Bidirectional optical bus systems for Ethernet networks
Inventor: BEZZAOUI HOCINE DR ING
IPC: H04B10/278
Filed: 1993-09-15
Abstract: The advantages of the Ethernet network are known, on the one hand for the simplicity of the transmission protocol, but on the other hand also for the simple network topology of the Ethernet bus system. While the optical transmission in Ethernet networks can easily be configured in the shape of a star, and therefore also exists already, since the transmission from point to point can be represented as a one-way system, the bidirectional optical transmission in Ethernet bus systems is as yet regarded as unknown. In this case, optical bidirectional transmission requires a direction identification means and a direction deciding means for supplying the data flow in the desired direction. It must be created, on the basis of the protocol concept according to ANSI IEEE 802.3, without any intermediate connection. This invention relates to novel circuits which are capable of optically changing over the data transmission in the case of all Ethernet bus systems operating according to IEEE 802.3.
