Patent DE-3719927-A1 (DE)
Title: Opposed-piston internal combustion engine having a central control groove on the piston rod between the pistons
Inventor: EICKMANN KARL
IPC: F02B75/18
Filed: 1987-06-15
Abstract: In an opposed-piston assembly in which a low-mass piston reciprocates in coaxial cylinders, the preferably hollow piston rod which connects the pistons, which are preferably thin, obliquely set plates having a low mass, is provided with a single control groove which controls successive fluid intakes from an inlet in the central housing between the cylinders in such a way that the inlet fluid flows into one of the cylinders at one time and into the other cylinder at a subsequent time. The plurality of control grooves in published patent applications of the inventor is thus reduced to a single control groove, the flow cross-sections are designed to have more favourable streamlining, the assembly is simplified, manufacturing costs are reduced and, at the same time, the efficiency and power output at a given weight of the assembly, which can be used particularly as a high-performance internal combustion engine, are increased. <IMAGE>

Title: Method for the production of a composite screen plate and a composite screen plate
Inventor: WEITERSHAGEN FRANZ-JOSEF
IPC: B01D39/10
Filed: 1987-06-29
Abstract: The subject-matter of the application is a method for the production of a composite screen plate and such a composite screen plate itself. It consists of a carrier plate made of steel, to the upper side of which is applied an anti-wear layer. The anti-wear layer is composed of a hard steel alloy with embedded hard materials. The composite screen plate has screen openings which are cut right through the carrier plate and the anti-wear layer. The intention is to provide a composite screen plate of this kind, the applied anti-wear layer of which has a uniform hardness in the direction of its thickness and has a smooth surface which poses a low frictional resistance to the abrasive screened material, without impairment to the reliability of the join between the anti-wear layer and the carrier plate. For this purpose, the anti-wear layer of the composite screen plate is composed of a sintered steel alloy which is sintered onto the carrier plate. The running of the sintered material gives a continuous and substantially flat surface and the join with the carrier plate is effected by diffusion at the boundary surface of the two materials.

Title: Process for separating off organic vapours from an air stream
Inventor: MAECKLE UWE DIPL ING
IPC: C07C29/76
Filed: 1987-08-08
Abstract: A process for separating off organic vapours from an air stream is described in which the air stream containing the organic vapours is passed over a semi-permeable membrane and the permeate penetrating through the membrane is removed from the permeate side (rear side) of the membrane. The rate of flow of permeate passing through the membrane can be increased several fold if a carrier gas stream is passed over the rear side of the membrane. Very favourable results are achieved if the carrier gas stream passed over the rear side of the membrane per square meter and hour is 50 to 300 l above the permeate volume passing through the membrane per square meter and hour. By the use of the carrier gas stream, it is also possible to operate the process without a pressure difference between the feed and permeate side.

Title: Process for conditioning and draining sludges
Inventor: SCHMITT WAELTI DIPL ING
IPC: C02F1/52
Filed: 1987-12-21
Abstract: In the conditioning of a suspension to be drained by mixing with flocculant, the optimum drainability depends on the quantity of the added flocculant and on the mixing energy expended. According to the invention, the sludge flocks present or formed after the flocculant has been mixed into the suspension are detected by measurement and, depending on their quantity, size and/or structure, the quantity of the flocculant and/or the mixing energy expended and/or the location of the flocculant addition are controlled.

Title: Pipe sealing clamp
IPC: F16L55/17
Filed: 1988-03-04
Abstract: In the case of a pipe sealing clamp, use is made of at least two clamp halves which can be braced with respect to one another and in which there is provided a radial groove which is directed towards the pipe which is to be sealed. Both segments of a pressure-exerting ring as well as a slit sealing ring consisting of an elastic material are accommodated in the radial groove. In order to ensure convenient and reliable handling of the clamp, it is proposed, in spite of the segments being left unconnected with respect to one another, to provide, on their side surfaces directed towards the groove wall, cutouts into which in each case one elastomer body, supported axially on the groove wall, is accommodated. This ensures reliable securing of the segments in the radial groove.

Title: Device for the measurement of optically excited biological information for non-invasive diagnosis in vivo and in situ
Inventor: BILZ DIETRICH DR
IPC: A61B5/00
Filed: 1988-04-12
Abstract: The invention relates to a device for the measurement of optically excited biological information for the targeted position-defined and volume-defined, regional and interregional continuous non-invasive spectroscopic and electrical diagnosis of microcirculation, metabolism and bio-periodic sequences in vivo and in situ, by the application of a combined device measuring electrically and optoelectronically, consisting of emitter components in the visible and infrared region, photoreceiver components and electrodes. The invention can be applied in biomedical diagnosis, especially of the brain, but also in heart, liver and muscle diagnosis. The electrode (electrodes) and the detector for receiving the non-ionising light transmitted locally at the same wavelength and in the same location sequentially with different intensity, scattered back sequentially at different wavelengths or wavelength ranges, are arranged directly at or else close to the point of entry of the light, and in the same plane. The invention enables, on the one hand, both the complete elimination of undesired information from tissue layers which lie in front of or behind the region to be examined or measured, but also the elimination of undesired information from the region to be measured, for example the blood volume and, on the other hand, a combined electro-optical and electrical reference measurement of optically excited biological...

Patent DE-3815085-A1 (DE)
Inventor: URBSCHAT KLAUS
IPC: F41A19/12
Filed: 1988-05-04
Abstract: A firearm lock (1) comprises a cocking device for a hammer (3), a locking device (5) with a catch element (14) which maintains the hammer (3) in the cocked position, and a trigger (6). To ensure that the hammer is effectively maintained in the cocked position as well as silent loading and firing of the weapon on gentle triggering, the locking device (5) of the striker (3) is designed as a switching mechanism with a control element (10) and a catch element (14). When the weapon is locked, the catch element (14), for example a ball, engages in a recess (11) in the control element (10), for example a spring cylindrical pin, and presses against the hammer (3). When the hammer (3) is cocked, the catch element (14) engages in a recess (16) in the hammer and presses against the control element (10) displaced by a spring (12). In order to fire the weapon, the control element (10) is displaced by the trigger (6) until the catch element (14) re-engages in the recess (11) of the control element (10), thereby releasing the hammer (3).

Abstract: In a method and an apparatus for structure testing, a determined structure is brought into binary form (302), the binary structure is expanded (303), the image size is reduced (305a), whilst maintaining the interconnection of the expanded structure, and is stored in a first store (306); furthermore, the binary structure is contracted (304), the image size is reduced (305b), whilst maintaining the interconnection of the contracted structure, and is stored in a second store (307). The expanded structure is then read out of the first store (306) and an interconnection of the structure is selected (308); the contracted structure is read out of the second store (307) and an interconnection is selected from this structure. The selected interconnections are compared with the interconnection of a normal structure, in order to determine a non-match. Corresponding to such non-matches, the structure having a short-circuit or partial short-circuit and the structure having an open or partially open electric circuit are classified and selected. Furthermore, the structure shape stored in the first store (306) is analysed in order to determine the position at which a short-circuit or partial short-circuit fault is present. <IMAGE>
