Title: Exhaust device for multi-cylinder internal combustion engines
Inventor: VISEK TOMAS ING
IPC: F01N13/10
Filed: 1988-05-05
Abstract: An exhaust device for multi-cylinder internal combustion engines has a cooled exhaust manifold (4). In the said manifold a tubular exhaust pipe is located in an air or gas-filled space at a distance from its walls. In order to prevent cooling of the hot exhaust gases inside the exhaust manifold (4), without increasing the dimensions of the latter and without having to accept an increased technical cost, the exhaust pipe comprises a straight pipe (3) inserted into the exhaust manifold (4) through a closable end opening (5). The circumferential surface of the said pipe (3) is cut out in the area of the exhaust ports (2) of the cylinders and the outlet opening (7) from the exhaust manifold (4). <IMAGE>

Title: Door-closure device for swing leaves
Inventor: HAMACHER WALTER
IPC: E05F3/00
Filed: 1988-07-20
Abstract: In the case of a door-closure device for swing leaves (3), in particular for swing/rolling leaves consisting of glass, there is provided, parallel to the door-closer shaft (15), a bearing shaft (18) which, together with a rotary-bearing pin, defines a pivot axis (12) for the swing leaf (3). The door-closer shaft (15) is connected to the bearing shaft (18) via a transmission element (10). The rotation of the bearing shaft (18) is transmitted to the swing leaf (3) via an arm (20). Said door-closure device makes it possible to dimension the spacing between the pivot axis (12) of the swing leaf (3) and the adjacent, fixed edge to be smaller than would be possible when using a conventional door closer alone. <IMAGE>

Inventor: SEEMANN GERHARD DR
IPC: C07K19/00
Filed: 1988-07-28
Abstract: Antigen constructs which result from linkage of major histocompatibility complex (MHC) Class I antigens to specific carrier molecules are described. The linkage takes place at the N or C terminus by covalent bonding or, in the case of non-covalent bonding, e.g. via avidin-biotin bridging. The specific carrier molecules bind selectively to target cells and are preferably monoclonal antibodies. Genetic engineering processes for the production of such constructs are indicated. Antigen constructs according to the invention are used for damaging or eliminating target cells. <IMAGE>

IPC: D02G3/46
Filed: 1988-09-17
Abstract: In mfg. a yarn, or partic. sewing thread, using a multifilament core and a second cladding material which is in intersecting loops around the core, the core is multifilament(s) with a strength of 60-75 cN/tex and is passed directly to the fluid eddy stage for cladding without preliminary drawing. Pref. the core component, satd. with a fluid, is subjected to eddies with a forward slip of 1-9%, while the cladding yarn component is passed to the eddy cladding stage with a forward slip of 14-35% (20-30%). The pref. cladding yarn component is a preoriented multifilament POY, given an initial drawing round pref. a heated pin before eddying, using a pin temp. of 110-150 deg.C (120-140 deg.C). The preorientation gives a drawing ratio of 2-40% (10-25). The specific strength of the cladding yarn component is pref. 20-75 cN/tex, and esp. 30-45 cN/tex or 60-75 cN/tex. For effective dyeing, the titre of the filaments in the core is 2-5 dtex (2.5-4.0 dtex), and the cladding filaments are 0.8-5.0 dtex (1-4 dtex). An unmatted multifilament is pref. for the cladding. The ratio of the mass of the core to the cladding is 90:10-50:50 (85:15-70:30). The pref. viscosimetric determd. mol.wt. is greater than that of a standard chemical fibre by 5-50% (by 10-25%). The multifilament core of 16-300 filaments (24-96), has a combined titre of 100-1000 dtex (100-600 dtex).

Title: Spinning-tube wet-spinning process
Inventor: NAGASAWA KEISAKU
IPC: D01F2/04
Filed: 1988-11-09
Abstract: In a spinning-tube wet-spinning process, a spinning fluid is extruded out of the orifices of a spinneret into a precipitation bath at a speed above a critical extruding speed, and the spinning fluid moves along an axis of the nozzle in an extended line as far as a deflection point and there is deflected in the direction of a spinning tube. The solidified yarn is drawn off through the spinning tube. The fibre obtained as a result of this process possesses outstanding properties. The wet-spinning process works in a stable manner, specifically at substantially higher working speeds than are possible in the conventional wet-spinning process.

Title: Procedure for cleaning motor vehicles - after waxing, vehicle is rinsed with water contg. agent which reduces its surface tension
Inventor: BURGER HORST
IPC: B60S3/04
Filed: 1989-06-08
Abstract: The customary process consists of washing, waxing and rinsing the vehicle. It is proposed that a surface tension reducing agent be added to the rinsing water. Waxing is to be carried out using cationic compounds, and rinsing is to be spread over the entire surface are of the vehicle and to take place under atmospheric pressure. Softened or purified water is to be used for rinsing. After rinsing, the film of water on the vehicle surface is vapourised by a hanging towel dryer or by a low-powered warm air dryer. USE/ADVANTAGE - This invention is used in cleaning the outside painted surfaces of motor vehicles. The proposed procedure ensures that the water remaining on the surface of the vehicle after rinsing will be in the form of a thin film, and not in the form of droplets, and so can easily be vapourised. Existing systems require high-powered dryers to remove the drops of water remaining on the vehicle surfaces.

Title: Piston for ink containers of refillable pens - is freely moving and has elastic sealing collar in angled recess which expands against outer wall during piston rod movement
Inventor: MATTHES GERHARD
IPC: B43K5/06
Filed: 1989-10-13
Abstract: The invention relates to a piston (2) in an ink container for a pen. The piston (2) moves freely in the ink container, but can also be operated by a piston rod (4). The piston (2) has two opposing angled surfaces (5) on the outer circumference forming a seat for a sealing  collar (6). During axial movement of the piston (2) by means of the rod (4) the frictional resistance between wall and seal (6) causes the collar to push axially on the angled surfaces (5) and thus increases radial pressure of the seal (6) on the wall. The seal (6) is elastic, typically polyurethane. USE/ADVANTAGE - Allows ink containers in pens to be refilled instead of the pen being thrown away.
