Title: Method for producing homogeneous test areas using defined spots (points) of light, in particular for perimeters
Inventor: KIRCHHUEBEL RAINER DIPL-ING
IPC: A61B3/024
Filed: 1981-09-17
Granted: 1982-12-09
Abstract: Test areas in, e.g., hemispherical perimeters, which are provided with precisely defined spots of light of predetermined intensity, have to be constructed such that when the spots of light are not activated the test area is completely homogeneous and has a uniform continuous colour without any patches. This is achieved by providing in the device bores which pass through as far as the surface of the test area, are of defined diameter, and in which mechanically processable optical fibres filling up the bores are inserted and attached in such a way that they project somewhat over the surface of the test area. The surface of the test area including the optical fibres is subsequently ground so that the optical fibres form a homogeneous area with the surface. In common with the optical fibres, the surface is then coated with a thin, matt and transparent lacquer film which has the same colour as the fundamental colour of the test area.

Title: Manual shift device for 5-gear transmission for motor vehicles
Inventor: WOERNER GUENTER
IPC: F16H59/04
Filed: 1981-09-17
Granted: 1983-01-27
Abstract: In such a manual shift device a gear shift lever shaft (7), kinematically connected to a manual shift lever (6), and three gear shift levers (8, 9 and 10) are supported in a bearing bracket (4). The gear shift levers (8, 9 and 10) have recesses (11, 12 and 13) and the gear shift lever shaft (7) has a shift finger (14) which can alternately be brought into positive engagement with the recesses (11, 12 and 13). One (10) of the gear shift levers (8 and 10) is used for shifting both the 5th gear and a reverse gear. In order to put the reverse gear in the shift pattern of the manual gear shift lever (6) into a shift slot (39) adjacent to the shift slot (38) of the 1st gear, the gear shift lever shaft (7) has an additional auxiliary shift finger (15) for the recess (13) of the gear shift lever (10) of the 5th gear and reverse gear together with a locking cam (16) and the bearing bracket (4) has two counter cams (19 and 20) alternately interacting with the locking cam (16) and acting only in one direction of rotation (17 or 18) of the gear shift lever shaft (7). <IMAGE>

Title: Process for the production of dental structures made of metal and coated with a plastic blend
Inventor: WUNDERLICH DIETER
IPC: A61C13/00
Filed: 1983-05-06
Granted: 1990-05-31
Abstract: The invention relates to a process for the production of dental structures (bridges and crowns) made of metal and coated with a plastic blend, the blend being obtained by applying a composition which can be polymerised to completion at room temperature on exposure to light and initially has a modelable consistency, and a filler-free liquid which can be polymerised to completion, likewise at room temperature on exposure to light, to give a solid, to the structure and subsequently polymerising the mixture to completion. In order that a dispersion layer or lubricating layer does not form on the surface of the blend composition during the polymerisation, the invention proposes placing the structure with coating in a liquid bath having a surface tension which is lower than that of water, instead of carrying out the polymerisation in air, and subsequently carrying out the polymerisation in this liquid by means of light.

Title: Thread-tensioning device for the weft threads of a weaving machine
IPC: D03D47/34
Filed: 1988-02-03
Granted: 1989-04-06
Abstract: The weft threads to be inserted into the shed in weaving machines are subjected, from the moment when the shuttle is thrown off to the moment when the shuttle is braked in the shuttle box, to considerably varying thread tensions which can lead to the insertion of the thread in the shed becoming irregular. In order to compensate these varying thread tensions during the insertion of the weft thread, a thread-tensioning device is proposed which automatically compensate the varying thread tensions via a pressure-loadable lever system, and this lever system or the pressure loading of this lever system can be set in a thread-dependent manner.
Patent DE-3812710-C1 (DE)
IPC: B21D43/12
Filed: 1988-04-16
Granted: 1989-04-27
Abstract: The invention starts from a transporting device for removing workpieces from a stamping machine, on which the stamping machine deposits the workpieces to be removed in at least two adjacent, laterally offset but unidirectional rows parallel to the direction of motion of the transport, the transport speed being the same over the width of the transport track. The invention consists in the fact that adjoining the rectilinear portion (5) of the transport track is a track portion (7) which runs at an angle (complementary angle x) thereto and the transport direction of which runs at right angles to the tangent (9) laid against the front edge of two adjacent workpieces (2) leaving the stamping machine. <IMAGE>

Title: Process and installation for producing a bung barrel from thermoplastic material
IPC: B29C65/02
Filed: 1988-04-29
Granted: 1989-03-09
Abstract: Process for producing a bung barrel from thermoplastic material, with a bottom part, top part and body, bottom part and top part having a body section and forming a bung barrel half and the two bung barrel halves being joined together under the application of heat by an encircling bond seal. The two bung barrel halves are in each case placed into an auxiliary device, these devices having a holder and a supporting means for the respective bung barrel half and being movable in the axial direction towards each other. The two bung barrel halves are received in the region of the bond seam to be produced by a centring ring, which has suction cups distributed over the circumference. A welding collar projects beyond the centring rings towards the bond seam to be produced. Arranged between the two auxiliary devices with the two bung barrel halves is a heating ring, into which the welding collars are introduced and in which the welding collars are heated to welding collar temperature. Thereafter, the auxiliary devices are moved apart. The heating ring is removed. Following this, the bung barrel halves centred with the aid of the centring collars are moved towards each other and the weld seam is produced as a butt weld seam.
Patent DE-3815858-C1 (DE)
IPC: E04G17/12
Filed: 1988-05-09
Granted: 1989-08-03
Abstract: In casings whose casing wall consists of a lattice covered with plastic film, the necessary stability of the casing is currently obtained by an L-shaped bending of the edge of the casing wall pointing towards the concreting base. However, this bending requires an additional operation and also needs a relatively large amount of material. So that the casing (1) can be produced and erected in a simpler and more cost-effective manner, a U-shaped assembly supporting part (8, 9) is arranged on the concreting base (13) and is used for supporting the casing wall (2), which, with unbent bottom edges (4a, 5a, 6a, 7a) directed towards the concreting base (13), is arranged on the assembly supporting parts (8, 9). The casing is particularly suitable for producing foundations. <IMAGE>

IPC: F02P7/03
Filed: 1993-10-22
Granted: 1995-03-09
Abstract: The invention relates to a distributorless ignition system for multicylinder, piston internal combustion engines with applied ignition operating on the four-stroke principle with an even number of cylinders, with an engine control module (2) for generating control signals determining the firing points of the cylinders, circuit breakers (12, 14, 16) connected to the engine control module (2) on the output side, and ignition coils (21-26) connected to the circuit breakers (12, 14, 16) on the output side and assigned to each cylinder, the circuit breakers (12, 14, 16) being actuated by the control signals and feeding the required ignition energy to the ignition coils (21-26). According to the invention each two ignition coils (21 and 26, 22 and 25, 23 and 24), which are assigned to cylinders, one of which performs a power stroke whilst the other performs an exhaust stroke, are connected to a common circuit breaker (12, 14, 16). This means that no high tension leads, the insulation of which can be maintained only with difficulty over a prolonged period and under all operating conditions, have to be laid. The cost is limited since the number of circuit breakers required is only half the number of cylinders. <IMAGE>
