Patent DE-3926581-A1 (DE)
Inventor: STRIGL REINHARD DIPL ING
IPC: B21C9/00
Filed: 1989-08-11
Abstract: The invention relates to a method for drawing wire, in which the latter may pass several times through     - a lubricant container (2) filled with lubricant (3),   - a lubricant pipe (4) arranged in the lubricant container, - a drawing die (5) arranged at the exit of the lubricant container and   - a drawing drum (6) arranged after the drawing die. The frictional processes due to the method generate heat, which limits the performance. It is therefore proposed, according to the invention, that the lubricant pipe arranged in the lubricant container be cooled at least to temperatures of about 0 DEG C, preferably below -30 DEG C, with a coolant fed to said pipe and removed again, it being possible, in particular, also to use highly cooled media, such as liquid nitrogen, as the coolant.

Title: Prodn. of high conductivity, high strength polymers - by (co)polymerising 5-membered N-,O-or S-heterocyclic(s) or aniline(s) in presence of polymeric sulphonic acids or salts
Inventor: NAARMANN HERBERT DR
IPC: H01M4/60
Filed: 1989-11-16
Abstract: The novel feature in the prodn. of electroconductive homo- or co-polymers by polymerisation in an electrolyte of 5-membered N-, O- or S-heterocyclics with conj. pi-electron systems or of aniline cpds. is that the polymerisation is effected in the presence of a sulphonic acid-substd. polymeric cpd. The polymsn. is pref. effected by an anodic oxidative process in an electrolyte or is effected with the aid of an oxidn. agent. An (in)org. substrate can be present during the polymsn. The sulphonic acid-substd. polymer is typically of formula (I), where X = -SO3 or its salt; R = H or Me; and Y = -COO- 1-4C alkyl, -CN, -COMe, -COHH, -CONH2, -CONH.CH2OR, Ph or Cl; m = 1-1000; and n = at least 2. USE/ADVANTAGE - The use of the polymers thus obtd. is electrode materials for primary or sec. batteries or as elec. conductors is claimed. The polymers have better electrical conductivity, mechanical properties and electrochemical deposition properties than prior-art polymers, e.g. those of DE3425511 in which a pyrrole- or thiophene-sulphonic acid is used as conductive salt. Typically, the polymers have tear strength above 50 N/mm2 as opposed to only ca. 36 N/mm2 for prior-art polymers. Also depositions of 1 wt.% can be achieved without damage to the polymer.

Title: Support for bringing infirm person from sitting to standing position - consists of inflatable cushion with sloping upper surface mounted on links
Inventor: SCHNAEBELE WERNER
IPC: A61G5/14
Filed: 1989-12-20
Abstract: An infirm or disabled person sitting in an easy chair often has difficulty in achieving a standing position. This difficulty is overcome by using an inflatable cushion. When deflated the upper surface is parallel to the lower surface. The upper surface is attached at its front edge to the front edge of the lower surface by pivoted links. These links restrain the upward movement of the front edge so that when the cushion is inflated the upper surface slopes downwards in the forward direction at an angle of about 10 deg. The chair occupant is thus brought to a standing position. USE - Chair for infirm persons.

Patent DE-4003752-A1 (DE)
Inventor: WILD ERNST DIPL ING
IPC: G01M15/10
Filed: 1990-02-08
Abstract: A process for associating combustion defects with a cylinder in an internal combustion engine which has at least one exhaust pipe between an exhaust gas manifold collecting site and a lambda sensor is characterized in that (a) the volume of exhaust gas, which depends on load and engine speed during intake, is determined for each exhaust cycle of a cylinder; (b) if a cylinder discharges exhaust gas, it is assumed that the calculated volume of exhaust gas enters the exhaust pipe at the collecting site of the associated manifold; (c) the volumes which enter the exhaust pipe at the collecting site are added until a volume equal to the volume of the exhaust gas pipe between the collecting site and the sensor is reached or even exceeded; (d) using the sequence of exhaust gas volumes entering the exhaust pipe which are allocated to the cylinders, the cylinder associated with the volume for which the above-mentioned sum condition is fulfilled is determined; (e) the signal emitted by the lambda sensor is evaluated; (f) if the sensor signal differs from the mean lambda value by more than a threshold value, the defect responsible for this difference is associated with the cylinder whose exhaust gas volume, determined as in step d, is just flowing past the sensor. This process can be carried out without special sensors. The results are reliable, even in the case of unsteady transitions, because individual exhaust gas volumes, each of which depends on load and engine speed, are added.

Patent DE-4005021-A1 (DE)
Inventor: EIKMEIER HEINO DIPL BIOL DR RE
IPC: G01N33/52
Filed: 1990-02-19
Abstract: Test carrier for analyzing a sample fluid with several test layers which form a sample fluid transport path and contain a reagent system which reacts with the sample fluid to produce a detectable signal. The test carrier includes a reservoir layer of absorbent material, a detection layer arranged in the fluid transport path downstream the reservoir layer, in which a detectable signal is formed, and a separating layer arranged between the reservoir layer and the detection layer. The separating layer makes a two-step process possible. Fluid contact between the reservoir layer and the detection layer arises only with pressure loading of the layer assembly of the reservoir layer, separating layer and detection layer. A more uniform optical detection signal, and consequently better accuracy, can be achieved because the separating layer is made up of a hydrophilic material, wich is in the form of a lattice-shaped structure, in which the mean width of the lattice openings is more than 0.05 mm, and the threads from which the lattice-shaped structure is formed are multi-filament.

Title: New 1-O-alkenoic acid ester(s) of carbohydrate(s) - used as glycosyl donors in synthesis of glycoside(s) and saccharide(s)
Inventor: KUNZ HORST PROF DR
IPC: C07H15/04
Filed: 1990-03-26
Abstract: 1-O-alkenoic acid esters of carbohydrates of formula R-O CO-R1-CR2=CR3R4 are new. In (I), R = a carbohydrate gp. bonded via an anomeric C and protected on the hydroxyl and opt. amino gps. by acyl, alkyl or acetal gps; R1 = aliphatic 1-12 (esp. 1-4C) gp. opt. interrupted by O, S or N and/or contg. an aromatic gp. opt. substd. by halogen, lower alkyl, lower alkoxy, CN, COOH or lower alkyl amino, a heteroaromatic gp. or a 3-7C cycloaliphatic gp; R2, R3 and R4 = each H, lower alkyl or aryl, which may also be attached to each other or to R1 to form a ring. (I) is pref. prepd. by reacting a carbohydrate which is not protected on its anomeric OH gp, with a carboxylic acid or its deriv. of formula X-CO-R1-CR2=CR3R4 (II). The carboxylic acid is activated with suitable condensing agents. X = OH or a gp. which activates carboxylic acids. The reaction is pref. carried out in the presence of silver or mercury salts if a glycosyl halide is reacted with (II) or in the presence of a Lewis acid if a glycosyl fluoride is used. USE/ADVANTAGE - (I) are intermediates in the synthesis of glycosides and saccharides which can be used in biological selected e.g. as membrane receptors. The novel activation principle for glycosylation reactions involves first protecting the anomeric hydroxyl gp. as a carboxylic acid ester, or as a carbonate or urethane and then activating the protected carbohydrate so that a lactone (or corresp. cyclic carbonate or urethane) leaves the anomeric centre as a leaving gp. The use of (I) allows mild conditions to be employed. The novel glycosyl donors (I) are stable, easy to handle and can be activated by weak electrophiles pref. those capable of attaching C=C double bonds.

Patent DE-4024942-A1 (DE)
Inventor: MAUS WOLFGANG
IPC: F01N3/28
Filed: 1990-08-06
Abstract: The invention concerns a monolithic honeycomb body through which a fluid passes in a particular direction of flow, with an upstream end (1) and, a certain distance from it, a downstream end (2). The honeycomb body consists of at least partly shaped metal sheet (4, 5, 6, 7, 8) which is disposed in layers and which forms channels (3) running approximately in the direction of flow and of dimensions determined by the structure of the sheet metal (7, 8, 9). To optimize the honeycomb body particularly for the conditions encountered in motor vehicles, the body has two or more sections (A, B, C) located one behind the other in the direction of flow and in which the number of metal sheets (4, 5, 6, 7, 8, 9) and channels (3) per unit cross-sectional area, and hence the cross-sectional area of the individual channels (3), varies. This variation is preferably achieved by using corrugated sheets of different corrugation height (7, 8, 9), the monolithic structure of the body being achieved by using continuous smooth sheets (4). Thus a honeycomb body can be produced which has for instance a small number of channels (3) in a first section (A) and a larger number of channels (3) in one or more other sections (B, C), hence improving e.g.the starting characteristics and the temperature distribution inside the honeycomb body.
