Patent WO-9961299-A1 (WO)
Inventor: JOEHR HANS
IPC: B62D1/19
Filed: 1999-05-20
Abstract: The invention relates to a steering device for motor vehicles, comprising a steering shaft that is guided by a guide box (3) which is connected to a retaining console and, for example, clamped. The console has at least one sliding surface (8) along the axis of the shaft (1) which allows for a displacement path (20) with respect to the chassis (18) in the case of a collision. Clamping means (17) are provided for axial retention of the console (6) in an initial position of said displacement path (20), whereby at least one part of the clamped surface is slanted in relation to the vertical clamping device so that the clamping surfaces can move away from each other when the steering shaft is displaced and clamping is reduced.

Title: Diagnosesystem und -verfahren für ein ventil
Inventor: PUETTMER ALF
IPC: F16K37/00
Filed: 2003-04-22
Abstract: Die Erfindung betrifft ein Diagnosesystem für ein von einem Stellungsregler (9) über einen Antrieb (6) betätigbares Ventil (2) mit einem Aufnehmer (12) für Körperschall und mit einer Einrichtung (14) zur Auswertung des aufgenommenen Messsignals (13) des Körperschalls. Bei einer Kalibrierung wird ein erster Verlauf des Messsignals bei geschlossener Stellung des Ventils (2) aufgenommen und daraus ein erster Wert (w1) einer Kenngrösse ermittelt. Zur Simulation eines Leckageschalls wird das Ventil (2) im Betrieb nahezu geschlossen, ein zweiter Verlauf des Messsignals aufgenommen und ein zweiter Wert (w2) ermittelt. Ist die Abweichung des zweiten Werts vom ersten Wert ausreichend gross, so ist eine Diagnose möglich, andernfalls nicht, da vermutlich der Druckabfall über dem Ventil zu gering ist. Im geschlossenen Zustand des Ventils wird ein dritter Verlauf des Messsignals aufgenommen und ein dritter Wert (w3) bestimmt. Bei zu grosser Abweichung des dritten Werts (w3) vom ersten Wert (w1) wird auf eine Leckage geschlossen, falls wie oben beschrieben die Möglichkeit einer Diagnose festgestellt wurde. Durch die Erfindung wird eine zuverlässigere Diagnoseaussage ermöglicht, ohne dass zur Erfassung der Betriebsbedingungen zusätzliche Messgeräte, beispielsweise Druckmessumformer, erforderlich wären.

Abstract: MIXTURES WITH PHYSIOLOGICAL (E.G. GALLSTONE ELIMINATING, ANTIVIRAL, ANTITOXIN) AND COSMETIC ACTIVITY. G3A. Consist of (a) any desired molecular grouping singly or multiply linked to di-nitrilo-R-carboxylic acid groups (e.g. benzoic acid p-di-nitrilo-R-tricarboxylic acid) (which can be mixed in the form of their salts with M-SO4, MM-SO4, M-PO4, MM-PO4, M-MO4, MM-MO4, M-O2 and/or MM-O2 cpds.) or (b) any desired molecular grouping which can have one or more nitrilocarboxylic acid groups (e.g. di-methyl-nitrilo-R-carboxylic acids). Activities mentioned are: elimination of gallstones, antivirus and antitoxin activity, local vasodilatory action (when applied in ointment form). When not properly adapted to the intended use and when administered over long periods, the mixtures can be damaging to health and vitamins, hormones, ferments and enzymes can be attacked. When this occurs, vitamins, and, if necessary, e.g. hormones, enzymes, ferments have to be added; such additive should be stabilized (e.g. by inclusion in hardened gelatin) that they only become active after 8-12 hrs. or the additives may be administered separately after an interval of 8-12 hrs.

Title: Methanol recovery from methyl acetate-methanol mixtures in methanolysi - s of polyvinyl acetate
Inventor: FRECHET PIERRE
IPC: B01D3/00
Filed: 1968-12-12
Abstract: The crude solvent mixture is introduced to a predistillation plate-type column heated by direct injection of steam. Methanol and methyl acetate are separated in the vapour phase while the non-distillable constituents are removed with the water of condensation. The obtained methanol-methyl acetate mixture is rectified in order to separate a first methanol fraction from the methyl acetate-methanol azeotropic mixture. This azeotropic mixture is subjected to a hydro-selective treatment in order to regain methyl acetate and aqs. methanol, and the latter rectified in order to separate methanol. Heat energy is saved; an anhydridrous methyl acetate-methanol mixture suitable for washing polyvinyl alcohol is obtained after the first step.

Title: Spur gear hardening press
Inventor: MOSNEAG IOAN
IPC: H05B6/10
Filed: 1970-05-05
Abstract: In order to both heat and cool spur gears when clamped, the press consists of separated upper and lower parts with separate hydraulic cylinders. One piston serves the holder for the workpiece, which centres and clamps it by means of a shoulder and jaws. It then raises the workpieces into a chamber with an inductor where the workpiece is simultaneously heated and rotated. After this, the workpiece is lowered into a basin where a coolant is applied and after release by the previous holder is pressed over a slide and against a pressure plate to prevent its distortion. The press is both fast and yields largely unwarped products.

Title: Fish fillet processing - with transfer mechanism between filleting machine and skinners
Inventor: KOERNER PETER DIPL ING
IPC: A22C25/08
Filed: 1972-04-20
Abstract: The two fillets of each fish lie on the rotating table on the filleting machine delivery side opposite ways up, i.e. 1 skin side down, the other belly cavity side down. The first of these is ejected radially, by a skimming wheel onto a downwards conveyor feeding it onto 1 of 2 skinning machines, whilst the second, over whose surface the skimmer slides, is ejected also radially by a curved fence so that it lies axially aligned on a rising conveyor whose top end is above a further descending conveyor feeding the second skinner. This second fillet is reversed during the transfer between the rising and descending conveyors so also reaching its skinner skin side down. Both skinners discharge into a common trough leading to the packaging etc. plant. Reduces labour cost.

Title: System for checking activity of catalytic reactors - signals bad functioning of such reactors and causes engine to run unstable
Inventor: SCHOECK PETER DR ING
IPC: F02M25/07
Filed: 1973-06-05
Abstract: In systems to neutralise toxic gases in exhausts of I.C. engines, a measuring sensor is located in the exhaust. This transmits the oxygen percentage to indicate the oxygen concentration-chain with ione-conducting fixed electrodes which could indicate a non-active catalytic contact. In that case the sensor will activate a warning signal and could interfere with the proper working of the engine, to warn that catalyst is not working properly.
