Title: GTO thyristor
Inventor: LUTZ JOSEF DIPL PHYS
IPC: H01L29/744
Filed: 1987-12-16
Abstract: GTO thyristors blocking only in the forward direction do not exhibit optimum turn-off behaviour for production reasons, due to adjustment of the structure of their one principal surface in accordance with the previously produced structure of their other principal surface and also on account of undesired turn-off losses. The GTO thyristor according to the invention has an improved turn-off behaviour due to optimised geometrical arrangement of cathode-emitter and anode-emitter sections with respect to one another and also due to reduced turn-off losses. The novel process for its production permits the desired geometry of the emitter sections of the two principal surfaces with respect to one another and the required concentration of heavy-metal ions in the region on the anode side for reducing the turn-off losses. In the case of the novel GTO thyristor, the impurity concentration of the cathode-emitter sections and of the anode-emitter short-circuit regions is identical and that of the cathode-emitter zone is greater than twice that of the anode-emitter zone. In the process, cathode-emitter sections and anode-emitter short-circuit regions are produced simultaneously, a surface oxide layer caused by the process is removed, and thereafter the anode-emitter zone is produced without a masking step. The GTO thyristor and process for its production relate to semiconductor components for high-current applications in power electronics.

Title: Process for quantitatively eliminating boron from carbidic boron compounds
Inventor: ROTH CARMEN DIPL CHEM
IPC: C01B31/36
Filed: 1987-12-18
Abstract: The hitherto known methods for liberating boron from carbidic boron compounds are unsuitable for quantitative conversions. The process for quantitatively removing boron from carbidic boron compounds is based on the use of cerium dioxide and/or other oxides of the rare earths and their mix oxides, which are added to the granular or pulverulent boron-containing carbidic compounds. The mixture is treated at elevated temperature with flowing steam, with boron being removed as boric acid and cerium dioxide and/or other rare earth oxides and their mixed oxides being able to be used again.

Title: Coriolis mass flow measurement with a measuring tube which can be deformed in its cross-section
Inventor: LANG MICHAEL DR
IPC: G01F1/84
Filed: 1988-03-14
Abstract: The invention relates to a method for mass flow measurement following the Coriolis principle. In this case, an elastically deformable measuring tube (1), flowed through by the fluid, is periodically deflected. As a measure of the mass flow, phase shifts between deflections of sections of the measuring tube wall (2) which are arranged differently in the direction of flow, are measured. The purpose of the invention is to provide a simply constructed mass flow meter in whose operation migration of the centre of gravity of the meter is largely prevented, and which is also suitable for large nominal diameters. For this purpose, a periodic deformation of the cross-section of the measuring tube (1) is proposed in such a way, that parts of the measuring tube wall (2) which lie diametrically opposite to each other are respectively deflected over approximately the same path in mutually opposed or in the same direction transversely to the direction of flow of the fluid. <IMAGE>

Title: In-line measuring cell for the measurement of the elastic and viscous behaviour of fluids
Inventor: WINDHAB ERICH DR
IPC: G01N11/02
Filed: 1988-06-03
Abstract: For the measurement of the viscous and elastic properties of fluids, a defined flow shape is generated in a flow channel. The loss of pressure in planar, parallel laminar flow (channel section having constant cross-section) is proportional to the fluid viscosity, the loss of pressure in expansion flow (channel section with defined variable cross-section) is correlated with the elastic fluid properties. The special shape of the flow channel in the subject of the invention allows the measurement of fluid viscosity and of an impirical elastic parameter by means of measurement of the static pressure at three places along the length of the flow channel. Fitting a measuring cell of this type directly into a product pipeline or into a bypass makes possible in-line measurement of the rheological fluid parameters as well as connection to a process control unit.

IPC: E06B3/68
Filed: 1988-08-02
Abstract: In order to brace the borders of panes (12, 14) which become soft and deform in the event of a fire, i.e. upon heating up, in order that the borders are prevented from slipping out, the ends of fastening screws (108) for the clamping mouldings (106) are screwed into spring elements (110) which draw the screws (108), and thus the clamping mouldings (106), towards the facade element (100), with the result that, even in the event of a fire, a sufficient pressure is exerted on the glass panes (102, 104) and the latter are held securely on the facade elements (100). The springs (110) are packed in non-combustible insulating material (114, 116, 118) in order to limit the temperature of the springs (110) within the period of time over which they are subjected to the fire (e.g. 90 minutes), such that the permissible application temperature of the spring steel is not exceeded and the given spring excursions and spring forces are maintained. <IMAGE>

Title: Reloading device for portable goods with a transportable container
Inventor: GEORG EDGAR DIPL ING
IPC: B65F9/00
Filed: 1988-08-20
Abstract: The transportation of refuse in the refuse collection vehicle to the landfill site or to the incineration plant is very expensive, on the one hand, due to the low loading quantity and, on the other hand, the currently great distances. Reloading from the refuse collection vehicle into a larger transporting vehicle previously required great building expense which cannot be carried out at all sites. A preferably mobile reloading device is proposed, which consists essentially of a container (2) which has the maximum permissible length and width dimensions for ordinary road traffic. The longitudinal side walls (5) can be moved from a narrow transporting position into a wide loading position so that a plurality of ordinary refuse collection vehicles can drive one after the other into the interior of the container and can empty their load directly. For transportation, the longitudinal side walls (5) are squeezed together, the container (2) is taken up by the transporting vehicle and driven to the landfill site for emptying. The refuse collection vehicles drive only within the collection district. The reloading device does not require any building measures and can be set up at a site which is favourable for the district in each case only on the refuse collection days. <IMAGE>

Title: Automatic focus adjustment for optical system
Inventor: SUDA HIROFUMI
IPC: H04N5/232
Filed: 1988-09-09
Abstract: A follower region adjustment device (11-20) variably adjusts object follow regions at a signal scan plane. A calculator (21-40) determines the difference of data over the difference of a predetermined signal component of an image signal between an internal and an external part of an object follower region selected by the adjustment device. This difference data indicates a sharpness adjustment parameter. An ascertaining device determines the position of an object in the scan corresp. the calculated difference and a sharpness adjuster displaces the sharpness measurement region to the position of the object on the scan plane by means of the ascertaining device. The adjustment device divides the region into n times m fields using each as a displacement parameter.

Patent DE-3842075-A1 (DE)
Inventor: KLENK MARTIN
IPC: F02D41/18
Filed: 1988-12-14
Abstract: Two processes for metering fuel are disclosed. In one process, the expected intake manifold pressure during the next intake cycle is calculated and used to determine the quantity of fuel to be injected for the next intake cycle. In the other process, the quantity of air determined using the intake manifold pressure is corrected by means of a model which takes account of the effects of temperature. Both processes make it possible to meter fuel more accurately than conventional processes, which is an advantage particularly in the case of unsteady transitions. The ignition timing can also be advantageously adjusted using the calculated quantities of air.

Title: Flood-protection arrangement and/or retention protection for environmentally hazardous liquid media
Inventor: GILLSCH JOACHIM DIPL ING
IPC: E02B7/00
Filed: 1988-07-12
Abstract: The known protection arrangement is to be improved in such a way that it guarantees immediate readiness for use for especially critical applications, e.g. for retention protection for environmentally hazardous liquid media. To this end, the tarpaulin which serves as a protective surface and can be acted upon overall by a pressure medium is permanently mounted with its sealing tube in the base element anchored in the ground. When the pressure medium acts on the tarpaulin, immediate binding of the sealing tube in the base element is obtained and as a result a protective surface is formed at the same time. The base element can be provided with a loosely seated, top cover.
Patent DE-3900240-A1 (DE)
Title: Amplifier circuit
Inventor: ZIERHUT HERMANN DIPL ING
IPC: H03F1/52
Filed: 1989-01-05
Abstract: In conventional amplifier circuits, power transistors must be used which are considerably overdimensioned with respect to their loading so that they are not destroyed when a short circuit occurs. Using the proposed measure of bypassing the resistor of a required RC section by means of a diode in the case of the occurrence of a short circuit, the capacitor of the RC section is rapidly charged up so that the power switching transistor is placed into the non-conductive state with corresponding rapidity. Since, therefore, the power transistor only needs to conduct the short circuit current over a significantly shorter period of time, there is also much less load on it so that the burning out of power transistors and amplifier circuits is considerably reduced by means of the measure according to the invention and power transistors with much smaller dimensions are sufficient with respect to the loading limit.
