Title: Process for producing a film tube (bubble)
Inventor: HESSENBRUCH ROLF DIPL ING
IPC: B29C48/10
Filed: 1989-02-02
Abstract: Film bags are overdimensioned if their wall thickness is dimensioned according to the stressing in the edge regions. There is a considerable material saving if only the peripheral regions of the intended folding edges of the film tubes intended for the fabrication of the film bags have the increased wall thickness. A process is proposed to produce such a film tube for the fabrication of film bags. According to this process, the reinforcing of a certain peripheral region of the film tube is accomplished by there taking place, in addition to the usual uniform peripheral cooling by cooling air at a cooling ring, a specific additional cooling of the extruded film tube, restricted to a narrow peripheral region, before the solidifying of the said tube.

Title: Device for producing a mechanical joining of sailboards and accessories
Inventor: CROPP RICHARD
IPC: B63B35/79
Filed: 1989-02-07
Abstract: In order to achieve a fastening of accessories to sailboards which is as practical as possible, a device has been developed which employs displacement of mouldings in order to clamp in a lateral fashion the parts to be fastened. For this purpose, the mouldings, which are displaced with respect to one another, have parallel faces which adopt an angle with respect to the direction of displacement. The displacement can be achieved by means of virtually all the possibilities known in technology for changing the distance between two hauling points. Particular emphasis is to be placed on the simple technical implementation, the low achievable weight and the absence of sensitivity to dirt of the device.

Title: Method of manufacturing footwear and last for manufacturing footwear
Inventor: RUEHRSCHNECK HELMUT
IPC: B29D35/00
Filed: 1989-02-28
Abstract: In a method of manufacturing footwear with injected-on outsole, the shaft is mounted on a two-part last and provided with an insole which is connected in a known manner to the shaft edge, after which the last is inserted into a mould and the outsole is injected on. Before the injecting-on of the outsole, the insole is arranged in such a manner on the shaft or shaft edge that it extends from the toe region in the direction of the heel region, leaving free a surface lying above the heel to be formed, that, after the injecting-on and setting of the outsole, the last is removed from the mould, that the last is adjusted by moving the rear last section in the direction of the front last section, as a result of which a shortening of the overall length of the last is achieved, that the last is subsequently removed from the footwear, that, by means of a displacement body projecting downwards from the last in the heel region, a recess or a cavity is established in the heel of the outsole, which is filled at least partially with elastic material, and that an inner sole running over the insole and the elastic material in the heel of the outsole is inserted.

Title: Internal combustion engine
Inventor: PUGLISI ALFIO
IPC: F02B31/06
Filed: 1989-03-01
Abstract: The aim of the invention is to provide an internal combustion engine, particularly a high-speed diesel engine with direct injection, in which the swirl of the air drawn in can be varied as a function of the operating conditions of the engine. The solution consists essentially in that the inlet spiral (11) which connects the intake opening (7) of a combustion chamber (5) to the intake duct (10) is assigned an additional channel (13) in which a flexible blade (14) is displaceably arranged. One end (20) of the blade (14) projects from the additional channel (13) into a connecting zone (15) between the inlet spiral (11) and the intake duct (10), allowing the cross-section of passage of the intake duct (10) to be throttled. The opposite end (19) of the blade (14) is connected to an actuating element (21) which is actuated by a control unit (22) responding to sensors (23). <IMAGE>

Filed: 1989-03-03
Abstract: The subject-matter of the invention relates to an optical rotation angle sensor. Optical rotation angle sensors having radial optical gratings, which can be swivelled about their centre, and stationary slits assigned to the said gratings are known. In order to reduce the manufacturing tolerances in conjunction with small dimensions, and to achieve a high resolution, it is proposed further to develop a rotation angle sensor by means of a second radial grating arranged parallel to the first optical grating, there being an overlap region of the two gratings and the centres of the two optical gratings (6, 7) being located in each case on different sides of the overlap region (21).

Title: Improved device for endoscopic polypectomy
Inventor: SIEGEL ROLF DR
IPC: A61B17/32
Filed: 1989-03-13
Abstract: The invention describes an improved device for endoscopic polypectomy. This is a tube which can be easily pushed to and fro in the biopsy channel by the person carrying out the endoscopy and in which there are, in a manner also such that they can be easily pushed to and fro by an operator, a) a polypectomy wire formed into a loop at its distal end and b) a "piercing wire" having barbs at its distal end. The "piercing wire" is arranged so that its distal end always projects through the loop opening of the polypectomy wire. At the request of the person carrying out the endoscopy, a helper "pierces" the polyp with the "piercing wire", and the polyp fixed in this way is then lifted from the organ wall under gentle tension and visualised in toto, and finally the loop opening of the polypectomy wire is wound around the polyp in the known manner. The "piercing wire" is in this process used as a guide and facilitates this manipulation.
Patent DE-3914763-A1 (DE)
Inventor: KUHLMANN WALTER
IPC: B65G23/14
Filed: 1989-05-05
Abstract: A stationary driving device for directing the goods carriers from the branch section into the main section of a power-and-free endless conveyor has two belts (13, 14) which circulate in parallel in the same horizontal direction and accelerate the load carriers (3) by means of a frictional connection. At the same time, the drive belts assume guide functions so that a building up of the load carriers on the running and carrying rail is effectively prevented. The drive device is also suitable for leading a loaded goods carrier evenly past the unloading point. Since no building up can occur here either, fully automatic unloading is possible when using known unloading devices. <IMAGE>

Title: Exhaust system for internal combustion engine - has baffle in exhaust pipe to create turbulence in exhaust gases
Inventor: LEISTRITZ HANS KARL DR
IPC: F01N3/38
Filed: 1990-01-05
Abstract: The IC engine has an exhaust manifold which increases progressively in dia. as a connecting duct from each individual cylinder is joined to it.  The manifold is connected by the  exhaust pipe (52) to the silencer (52) with a conical pipe (5200) connecting the two parts (52,521). The conical pipe (520) encloses a smaller dia. pipe (71) which passes through the end wall of the silencer.  The open end (71a) of the pipe (71) is partly covered by a baffle plate (513) which prevents the exhaust gases from flowing directly into the silencer.  This baffle plate (513) creates a turbulence in the gas flow which increases the effectiveness of the post-combustion of the environmentally harmful products in the exhaust gases. USE - IC engine exhaust system.
