Patent DE-4303817-A1 (DE)
Title: Device for examining the surface fatigue of materials
Inventor: JOKL MICHAEL
IPC: G01N3/56
Filed: 1993-02-10
Abstract: In known devices for testing surface fatigue, test arrangements with two or more rollers or spheres are used. The test bodies move in such a way that a roller friction with or without slip is produced between them. The relatively complicated shape of the test elements and of the necessary test device makes the surface fatigue examinations, which are also long-term examinations, expensive and uneconomical for series investigations. The new device is intended to use a simple friction pair and movements and as a result to permit simple and reliable testing of the surface fatigue of the materials. A friction pair is used which consists of a diamond collar pressed against a plate made of the material to be tested. The extremely low adhesion of the diamond in comparison with all the materials permits the use of pure sliding between the friction elements to produce periodic stresses of the plate surface. In the absence of adhesion wear, the surface fatigue appears in the form of pittings on the surface of the plate after a specific number of cycles.

Inventor: SCHWABEN HANS-DIETER DR
IPC: C08F257/02
Filed: 1993-06-09
Abstract: A process for recycling used polystyrene (PS) articles comprises dissolving the PS in styrene monomer, purifying the soln., possibly adding a rubber, polymerising in a conventional polymerisation system and removing residual solvent. The process comprises heating styrene to 60-110 deg.C., adding 1-25 wt.% old PS and dissolving by stirring, adding 0.2-3 wt.% active carbon (pref. particle size above 100 microns), stirring for 15-90 minutes. at 60-110 deg.C, removing any paper, Al etc., filtering or centrifuging at 40-90 deg.C. and 2000-6000g to remove carbon and any TiO2 etc., opt. adding ethylbenzene (EB) to make the soln. less viscous, polyerising for 4-10 hrs. at 100-180 deg.C. in presence of radical initiators and chain transfer agents etc. to give a 65-85 wt.% soln. of PS, opt. adding polybutadiene or SB block copolymer etc., and removing solvent in a degassing zone. USE/ADVANTAGE - The process enables PS articles (packaging etc.) to be recycled as opt. rubber-contg. material suitable for new high-grade packaging; the amt. of solvent which has to be removed from the purified PS is significantly less than in prior-art processes.

Title: Process for purifying solvent-containing exhaust air by adsorber resins
Inventor: HELLINGS GABRIELE
IPC: B01D53/04
Filed: 1993-06-16
Abstract: A process is described for purifying exhaust air which contains aggressive organic solvents such as tetrahydrofuran and/or cyclohexanone, the adsorbent being a monodisperse macroporous ion exchanger without functional groups based on polymerised synthetic resins. The adsorbent preferably used, since it virtually has close hexagonal sphere packing, has a high bulk density and therefore a high adsorption capacity, the moisture and CO2 in the laden exhaust air not being adsorbed, while the said solvents are virtually completely adsorbed. The desorption can proceed in a broad temperature range under the action of inert gas, preferably nitrogen and/or CO2. The adsorber is also suitable as a buffer for collecting solvent peak loads.

IPC: F02M61/16
Filed: 1993-08-20
Abstract: Dans les soupapes d'injection commandées électromagnétiquement connues, il y a un support de siège de soupape et une aiguille de soupape réalisés dans le même matériau, par exemple de l'acier au chrome. Lorsque le carburant et la soupape d'injection sont chauffés, les deux composants de la soupape arrivent à la même température et leur longueur se modifie dans les mêmes proportions, en raison de coefficients de dilatation thermique identiques. La course de la soupape demeure de ce fait constante. Les bulles de gaz formées dans le carburant chaud au cours de l'échauffement entraînent cependant une diminution du débit de passage du carburant. La nouvelle soupape d'injection doit permettre de compenser la diminution du débit de passage, grâce à un choix judicieux de matériaux. L'utilisation, pour réaliser l'aiguille (6), d'un matériau à très faible coefficient de dilatation thermique, fait que l'aiguille d'injection se dilate moins par rapport au support du siège d'injection (1) lorsque la température augmente. Cela provoque une augmentation de la course et empêche une diminution de la quantité de carburant dosée due à la formation de bulles de gaz. La soupape d'injection convient particulièrement aux dispositifs d'injection de carburant de moteurs à combustion interne à allumage commandé et compression du mélange.
