Filed: 1987-03-13
Abstract: The bar-type ignition coil (12) has two projecting shoulders (14), and the claw (18) has two flanges (20) which point inwardly and face one another. Both flanges (20) press on the shoulders (14) and thereby ensure, when the claw (18) is secured by screws, that the ignition coil (12) is in the correct operating position. To withdraw the coil (12) from the recess (11), the two flanges (20) engage under the shoulders (14), so that the claw (18) acts as an extraction device. Thus, the claw (18) is firstly a means of securing and secondly a tool for withdrawing the ignition coil (12).

Title: Circuit arrangement for controlling and/or regulating the spindle speed on ring-spinning or ring-twisting machines
Inventor: BEIER BENNO DR ING
IPC: D01H1/30
Filed: 1987-11-23
Abstract: In a known circuit arrangement, digital signals are emitted, counted in a counter and evaluated in subsequent digital/analog converters and the now analog signals are processed. This can be carried out only at a high outlay in terms of circuitry, and also there is no free programmability. An incremental pulse generator (6) for emitting digital signals resulting from the continuous lifting movement of the ring rail (4) and a pulse generator (7) for emitting digital signals resulting from the traversing lifting movement of the ring rail (4) are connected to the ring rail (4) and are followed by a common digital processing unit (8). The circuit arrangement makes it possible to control and/or regulate the spindle speed on ring-spinning or ring-twisting machines in dependence on the position of the ring rail in the light of the continuous lifting movement and traversing lifting movement. <IMAGE>
Patent DE-3743293-A1 (DE)
Title: Flat tube for heat exchangers
Inventor: BROST VIKTOR DIPL ING
IPC: F28F1/02
Filed: 1987-12-19
Abstract: A flat tube for heat exchangers is proposed which has two plane broad walls and two narrow walls which have an outwardly directed camber with an arcuate transition for the two broad walls. The outward camber is selected with only a slight advance curvature and in such a way that the course of the curvature of the outward camber with the two arcuate transitions is relatively weak and is somewhere between the course of a conventional semicircular arc and of a right-angled connection of each narrow wall to the two broad walls, both of which are unfavourable. The weak outward camber results in greater strength (stability) and renders it possible even in these end regions of the flat tubes to make additional use of the surfaces there for heat exchange purposes, doing so inside and outside where lamellae respectively adjoin, with the result that the heat transfer capacity is increased.

Title: Method and device for producing and using 0.5 MeV S-photons and 0.5 MeV S-gravitinos
Inventor: STROBEL CHRISTIAN M DIPL ING
IPC: G21K1/00
Filed: 1988-02-09
Abstract: A description is given of a method and device with which and on which the older invention by the author, namely the production of 0.5 MeV photons by collision of artificial protons with electrons, the electron being annihilated to give a 0.5 MeV photon, but the photon being unannihilated and reacting further, is replaced and, in a cheap way again, positrons in collision with electrons are both annihilated and each deliver an energy quantum of 0.5 MeV. For this purpose, in a common vacuum, electrons are produced from one thermionic cathode and positrons from a second, and the two are directed so that they collide with each other and together deliver twice 0.5 MeV = 1.0 MeV, the energy of the two photons, namely the positron photon and the electron photon. The method can be used for medical and technological X-ray diagnosis and preferably for heat generation in the red-shift reactor, but also for many other purposes. In this way, when used for power generation through heat recovery in the interaction of 0.5 MeV photons and 0.5 MeV gravitons, using positrino photons from the accelerators and positron sources shown in the figures, the scale necessary for the required power is not yet unlimited, and, for high powers, further developments and inventions may still be necessary in this respect.

Patent DE-3811498-A1 (DE)
Title: Dental jaw implant
Inventor: WITZEL ULRICH DR ING
IPC: A61C8/00
Filed: 1988-04-06
Abstract: In a dental jaw implant a rigid shaft is accommodated so as to be tension- and pressure-resistant in an axial recess in a socket of entropy-elastic plastic whose front face pointing towards the occlusal surface holds an artificial tooth or a dental structure, where appropriate with interposition of a supporting component. The shaft itself and/or the supporting component have a collar which is supported on the front side of the socket pointing towards the occlusal surface. The tension- and pressure-resistant connection between shaft and socket is restricted to an axial connecting zone which is short in the axial direction and points towards the occlusal surface. The remaining axial area of the shaft is surrounded by surface and/or supporting elements. With elimination of any significant transmission of an axial force between shaft and socket, these elements guide the shaft during its axial movement caused by the chewing force inside the remaining axial area relative to the outer wall surface of the socket. An axial space is left between the deepest point of the socket and the front side of the shaft. On maintenance of a tension- and pressure-resistant connection between socket and implant shaft the jaw implant permits a physiological force to be exerted upon the jaw.

Title: Soot burn-off filter for diesel engines
Inventor: THIEMANN KARL-HEINZ DIPL ING
IPC: F01N3/022
Filed: 1988-05-06
Abstract: A soot burn-off filter comprising a monolithic filter block of porous ceramic material is provided with a plurality of gas ducts running in the main direction of flow of the exhaust gases, which ducts are alternately closed by plugs, in order to force exhaust gas to pass through the porous duct walls from the inlet ducts into outlet ducts. In order to prevent compressive or tensile stresses between the more rigid plug area and the remainder of the filter due to a variation in the length of the filter material during heating and cooling, the plugs are made from a material having glass-like characteristics. The said material changes into a softer state in the soot burn-off temperature range, but without melting. By virtue of this characteristic, the plugs can follow the movements of the filter material without stresses leading to the formation of cracks.

Title: Brake-pad wear indicator for motor vehicles
Inventor: PIORR MICHAEL ANDREAS
IPC: F16D66/02
Filed: 1988-06-08
Abstract: The intention of the brake-pad wear indicator is to signal excessive and dangerous wear of the brake pads on a motor vehicle by means of a warning light mounted in the motor-vehicle dashboard. A PVC-coated copper cable embedded in the brake pad is torn when the brake pad is nearly totally worn out. Since when the engine of the motor vehicle is being started the cable is connected to the current from the weak-current side, a relay signals by way of a light mounted in the dashboard when the copper cable tears, i.e. when the brake pads have reached a dangerous state of wear. The reference symbols in the drawing signify     1. brake pad   2. PVC-coated copper cable.   <IMAGE>

Title: Arrangement for connecting electronic modules and components
Inventor: MENNENGA HEYO PROF DR SC TECHN
IPC: H05K1/02
Filed: 1988-06-25
Abstract: The invention is used in the manufacture of microelectronic functional units for connecting modules and components, for which purpose plug connectors and solder connections are known. Plug connectors are complicated and expensive components. Solder connections are simpler and quicker to make, but have the drawback that the often required capability to detach them, at least in principle, is not provided. The aim of the invention is to avoid expensive plug connectors and replace them by solder connections. The object of the invention is to provide a multipole solder connection which is nevertheless easy to detach and reproduce. This object is achieved, according to the invention, by fitting the arrangement according to the invention between the elements to be connected, which arrangement has a base body in which the contact pins are integrated with solder surfaces, and is characterised in that it has at least one, preferably electrical, heating device as well as associated connecting elements for supplying the heat energy. With activation of the heating device, the base body is heated and, with it, the solder surfaces, and the solder present on the latter is thus melted. Dismantling or assembly of the connection is then possible. After deactivation of the heating device the operation is finished. The invention has substantial advantages in comparison with plug connectors wherever multipole contacts are made or detached only very rarely... Original abstract incomplete. <IMAGE>

Inventor: SCHAEFER HEINRICH
IPC: F21V9/08
Filed: 1988-08-03
Abstract: A motor vehicle light, in particular a reversing light, has an intermediate glass (4) between its incandescent lamp and the lamp glass. Illumination from the lamp is reflected in a parallel beam falling on an alternating pattern of convex surfaces (5) and V-grooves (6) on the inner face of the intermediate glass. The outer face of the glass is in the form of a screen having light passages (8) separated by light-impermeable surfaces (7). Optically effective surfaces (9) of the light passages are in alternation to each other inclined in opposite directions to the axis of the beam. The light passages are directly opposite the convex surfaces of the inner face. The V-groove surfaces deflect the light through them onto the front face light passages. In this manner, an effective distribution of illumination can be achieved from the vehicle light. <IMAGE>
