Title: Fuel system for a motor vehicle
Inventor: ANHEGGER SIGMUND
IPC: B60K15/035
Filed: 1988-01-19
Abstract: In a fuel system for a motor vehicle, the fuel passes from the fuel tank by way of a feed line to an intake system of the internal combustion engine, the fuel not required being fed back to the fuel tank from the intake system by way of a return line. In addition, a venting line of the fuel tank is connected to an activated charcoal canister. So that liquid or condensed fuel is prevented from flowing into the activated charcoal canister under all operating conditions of the motor vehicle, a collecting vessel is arranged in the venting line upstream of the activated charcoal canister. The fuel accumulated in the collecting vessel is returned into the fuel tank by way of the return line.

Title: Semiconductor device
Inventor: ARAI HAJIME
IPC: H01L23/29
Filed: 1988-02-22
Abstract: A semiconductor device is described in which an inorganic polymer layer (13), especially a silicon conductor polymer layer, is used as a buffer layer or  alpha -radiation shield. This layer has excellent thermal stability and very good electrical properties such as, e.g., a low dielectric constant and a low dielectric dissipation factor (loss tangent). The semiconductor device thus offers the advantage that it provides for high reliability and rapid operation of the components at the same time as low power absorption (Figure 3). <IMAGE>

Title: Arrangement for measuring the current loading of MIS structures in the production and assembly of components containing MIS structures, and measuring methods
Inventor: SPITZER ANDREAS DIPL PHYS DR
IPC: G01R31/26
Filed: 1988-02-24
Abstract: The arrangement contains a MIS structure containing a multilayer dielectric (2). The multilayer dielectric (2) has three layers (21, 22, 23), which are tuned to one another in thickness and composition such that the centre (22) one of the three layers has a high capture cross-section for charge carriers in the event of current loading, and that in this case the captured charge carriers are no longer removed by the flow of current. The characteristic electric measured values of the MIS structure, which are influenced by the captured charge carriers, are recorded and compared with calibration values. It is possible thereby to deduce the current loading. <IMAGE>

As in an axle drive, the drive motor, the clutch, the drive shaft carried on thrust bearings and having an axial curve, the transmission elements and the rectilinearly guided machine subassembly to be driven are arranged in alignment one behind the other.
Patent DE-3813815-A1 (DE)
IPC: F16L37/12
Filed: 1988-04-23
Abstract: The invention relates to a two-piece metallic clamping connector for pipes and hoses, consisting of polymer material. In this case, a connecting piece (1) designed as a pipe sleeve is used, having a plug-in region (11) which is to be inserted into the pipe end (21). There is furthermore a sliding sleeve (3), which can move axially with respect to the pipe axis, and which can be pushed over the pipe end (21) with the plug-in region (11) inserted, to produce the clamping connection. The invention is seen in that the sliding sleeve (3) has a conical recess (32), running from the outside to the inside over its wall cross-section, on its free end (31) facing the flange projection (110). This conical recess (32) makes a transition via a radius (34) into a cylindrical section (35). A hollow channel (33) is fitted in a circumferential manner into the inner circumferential wall of the sliding sleeve (3), adjacent to the cylindrical section (35). <IMAGE>

Title: Brick element for a self-supporting roller-blind casing in the form of an upside-down U and roller-blind casing of this type and process for the production thereof
Inventor: HIERSTETTER FELIX DIPL ING
IPC: E06B9/17
Filed: 1988-06-16
Abstract: Brick roller-blind casings in the form of an upside-down U may be produced from sub-elements which consist of brick material and have a mutual arrangement in the brick blank which differs from their arrangement in the roller-blind casing, in order to simplify the production. The invention proposes a brick blank which, in production terms, is just as simple to manufacture as a vertically perforated brick of the conventional format and, nevertheless, makes it possible to erect the roller-blind casing in an extremely simple manner, the mounting position thereof corresponding to the installation position, and the sealing not requiring any special auxiliary means. By means of shuttering portions (5) which jut out over the upper web (12) of the roller-blind casing and consist of brick material, there is integrated a lintel which is configured in the manner of a flat brick lintel and renders an additional lintel superfluous. For force transmission, prefabricated head pieces consisting of brick material or of lightweight concrete are arranged, at the ends of the roller-blind casing, with a statically required bearing surface, on the masonrywork which is supported on the sides of the wall opening, which head pieces permit clean force transmission from the lintel. By corresponding dimensioning of the sub-elements of the brick blank, a simple, unit-like adaptation to any desired wall thickness can be achieved, while the overall height of the roller-blind casing facilitates a disruption-free integration into the masonry-wall assembly. <IMAGE>

Title: Ceramic superconductor parts made with higher current density - by using magnetic field to orient crystallites during filling of forms before compression at elevated temp.
Inventor: KRIECHBAUM KARL DR
IPC: C04B35/45
Filed: 1989-09-11
Abstract: The high temperature superconductive parts based on ceramic are made by compression of a powder. Before and possibly during the compression stage the crystallites are oriented by a magnetic field to align the axes of highest critical current density in parallel. The powder particles are pref. vibrated, pref. by ultrasonic agitation. Pref. two concentric hollow tubes (1,2) are used between which the powder is compacted by expansion of the inner tube radius. The inner tube pref. consists of a ductile material, pref. Ag, which is expanded by gas pressure, pref. O2. The outer tube is pref. Ti or steel. The thick film mfg. method uses 2 parallel plates between which the powder is compacted. The compression pref. is carried out under O2 pressure while at least one of the plates is permeable to this. Afterwards the material is sintered, pref. under pressure, while the magnetic field is pref. maintained. USE/ADVANTAGE - The magnetic field improves the orientation of crysallite axes and as a result allows the crystallite orientation to be adjusted for max. critical current density.

Title: Continuous prodn. of synthesis gas - by reforming methane using carbon di:oxide as fuel gas
Inventor: CZIMCZIK ARNO
IPC: C01B3/34
Filed: 1989-10-05
Abstract: Synthesis gas is continuously produced by solar reforming methane, in which a fuel gas for convective warming of the reaction partner is heated with the solar energy to a high temp.. When there is a lack of solar energy an auxillary firing agent is used to heat the fuel gas. The novelty is that CO2 is likewise used as the fuel gas for CO2 reforming methane produced by auxillary firing and stored as the reaction partner for CO2 reforming. An appts. for carrying out the above process is also claimed. In the auxillary firing process methane is burned with O2-enriched air or with pure O2. The auxillary firing process is carried out without pressure via a burner or under pressure in a burner connected to a gas turbine. A portion of CO2 is pref. added to the auxillary firing stage as moderator gas. ADVANTAGE - The process avoids using explosive mixts..

Title: Method of damping dynamic profiles - with damping load characteristics controlled to counteract resonant frequencies
Inventor: BSCHORR OSKAR DIPL ING DR
IPC: B64C9/30
Filed: 1989-10-27
Abstract: The aerodynamic profile, is subjected to a slipstream which generates resonance at set frequencies.  The resonance is reduced by having the effective resistance of the resonant system greater than the external forces on the system.  The damping can be adjustable with flow speed. The damping system has a damping loading (13) on an elastic surface (11) linked to the damping mass (12).  The damping mass can also be effectively used e.g. the fuel inside an aircraft wing, by having elastic gas pockets inside the tank, with controlled pressure. ADVANTAGE - Active damping system, less stress on structures.
