Inventor: VIEL PAUL
IPC: B32B3/20
Filed: 1988-06-08
Abstract: Modern structures are being erected more and more often in a lightweight type of construction. Concrete is being replaced by latticed elements which are then clad (facades, glass areas, solar cells). The structural element described here can perform a number of functions at the same time, by basic elements being supplemented by additional elements. The structural element described here can be used as a float, as a modular assembly for large projects and as a heat exchanger, lightweight construction, high strength and practical function being combined in one.

Inventor: TRILLER ADOLF
IPC: A61B3/10
Filed: 1988-06-29
Abstract: A device is described for producing an image of an object, and in particular for surveying the eye with an illumination source whose light can be focused on the object section to be surveyed, a scanning device which produces a scanning movement of the light beam of the illuminating light source above the section to be surveyed and has beam-deflecting and imaging optical elements, a detector device (sensor device) which receives the light which is reflected at the section to be surveyed, and an evaluation and synchronisation unit which produces an image of the selected object structures from the time-sequential output signal of the detector device. The device according to the invention is characterised in that an arrangement of at least two imaging optical elements is provided in the beam path between the beam-deflecting elements, which arrangement can be replaced to change the horizontal deflection angle.

Title: Adjustment device for adjusting the braking force of a brake device
Inventor: BERGER SIEGFRIED
IPC: B60T8/18
Filed: 1988-08-20
Abstract: A known adjustment device is not capable of guaranteeing an acceptable utilisation of the friction on the wheels of a vehicle as expressed in the friction curves according to the EC Guideline or an optimum utilisation of the installed braking potential as is possible according to the reference manual of the EC Guideline. The invention identifies an adjustment device which rectifies this disadvantage. The invention proposes that a valve device be connected upstream of the load-dependent brake pressure control device (anti-wheel-lock braking system), which device from a predefined control pressure onwards has a pressure reducing characteristic. The invention has applications in vehicle brake systems. <IMAGE>
Patent DE-3829920-A1 (DE)
Title: Process for recovering carbon disulphide from spinning baths
Inventor: EBNER KARL
IPC: C08J11/02
Filed: 1988-09-02
Abstract: To recover spin bath ingredients (e.g. carbon disulphide), they are degassed at reduced pressure. The gas mixture obtained is then cooled to condense its water vapour content and then compressed to atmospheric pressure. However, carbon disulphide cannot be condensed out of the remaining gases by subsequent pressurisation since the formation of ice on the cooling surfaces makes adequate cooling impossible. According to the invention, the residual gases compressed to atmospheric pressure will be stripped of their water vapour content by means of sulphuric acid. The remaining gas mixture can then be cooled down to temperatures below 0@C.

Title: Adder circuit for serial addition of BCD 8421-coded decimal digits
Inventor: MERKLE PAUL
IPC: G06F7/495
Filed: 1988-12-27
Abstract: The serial adder circuit according to the subject of the invention consists of a dual full adder (1), in which the tetrads are serially added to each other, and a correction circuit (5), using which the number 6 (LHHL) may be added to the intermediate result number, which is stored in the shift register (3). The intermediate result number is raised by the number 6 in circuit (5) if the OR circuit (11) has high potential at its output, and not raised by the number 6 in circuit (5) if the OR circuit (11) has low potential at its output. Thus the possibly corrected intermediate result number can be input in parallel via the gate circuit (6) into the shift register (4) on the fifth clock cycle, on which the shift register is not controlled by the cycle. Circuit (5) is an adder circuit for the number 6, and consists of four dual half adders. <IMAGE>

Title: Process for converting special waste from domestic waste into another product, both products occuring as electrostatic precipitator dust
Inventor: FINKE PETER O DIPL PHYS
IPC: B09B3/00
Filed: 1989-02-20
Abstract: The invention relates to a process for converting special waste from domestic waste into another product, both products occuring as electrostatic precipitator dust. The object of the invention is to bind the electrostatic precipitator dusts from waste incineration by other electrostatic precipitator dusts, e.g. by dusts arising in the use of brown coal for power generation, the surface-active treatment of the surfaces having to exhibit both hydrophobic and hydrophilic properties and the completed mixture being given an additional hydrophobic treatment before its final solidification. The proportional composition of these ash groups having different specific gravities must be determined by experiment. Such a product serves, inter alia, for the liquid-impermeable lining of underground tanks.
Patent DE-3911474-A1 (DE)
Title: Interferometer using waveguide technologies
IPC: G01B9/02
Filed: 1989-04-08
Abstract: The application of integrated optical technology or glass fibre technology in interferometry yields advantages by comparison with the classical design. On the other hand, novel problems are thrown up which occur as a consequence of the technology, in particular owing to the splitting and recombining of the beam as well as to the shifting of the phase of the output signals. The profitability (economic efficiency) is thereby called into question. By suitably coupling the radiation into the waveguides and displacing the interference phenomenon outside the waveguides, the splitters are eliminated and the connection of a plurality of interferometers or interference refractometers to one divider is rendered possible. <IMAGE>

IPC: B01D21/00
Filed: 1989-08-28
Abstract: A slurry contg. particles, esp. of metals, with greater density than the remaining material, and possibly in a wide spectrum of particle sizes, is fed through an axially aligned inlet (3) into the inclined cylindrical housing (1) of a gravity concentrator. The annular space (8) between inlet pipe and housing has on its high side a radial inlet (4) for a sepn. medium, esp. water, and on its low side an outlet (5) for heavy particles. Light fraction material is radially discharged (6) from the upper end of the housing.

Housing interior and inlet pipe exterior may both be corrugated. ADVANTAGE - Gradual change from turbulent to laminar flow ensures effective sepn. e.g. of particles with density range 2-60 and with min. consumption of water, which can be recycled.

Inventor: GOLDSTEIN PETER
IPC: H04Q1/444

Title: Automatic operation for vehicle tailgate door - has hydraulic system with controlled servo motor drive, sensitive to obstructions in door gap
IPC: E05F15/04
Filed: 1990-03-07
Abstract: The tailgate is moved about its horizontal axis by a servo ram (2) coupled to a drive cylinder (3) driven by an electric servo motor (35). The servo ram piston (22) has a non-return valve, closed in the power stroke, and a flow restriction (4). The latter provides for a controlled closing of the flap when the drive cylinder is reversed. The movement of the drive motor is controlled by a speed sensor (9) which determines the end of movement of the door action. A gas spring (G) integral to the servo ram provides a cushioning effect. Obstruction jammed into the door are sensed by the change in speed of the drive motor and a reversal drive is initiated to release the obstruction. ADVANTAGE - Compact servo drive, failsafe.
