Title: Rotary engine
Inventor: EGGERS THIES
IPC: F01C11/00
Filed: 1987-04-15
Abstract: A rotary engine, the piston of which, edged by a number of identical profile curves, divides a number of chambers equal to the number of profile curves inside a stator chamber, with uniform chamber division in the circumferential direction, with an inlet and an outlet into the stator chamber and with a radial slide valve between inlet and outlet. The technical problem is to design such a rotary engine so that the radial slide valve can be actuated essentially without loss of work. Two cylinder chambers (2) each with a rotary piston (4, 5) are arranged in series in an axial direction. The two rotary pistons (4, 5) are staggered in a circumferential direction by half the chamber division. The profile curves (8) of the rotary pistons (4, 5) are designed in such a way that in the circumferential direction the rise of one profile curve is equal to the fall of the corresponding profile curve of the adjacent rotary piston and vice versa. The two radial slide valves (17, 18) are guided in shoulders of a hydraulic chamber (21). <IMAGE>

Title: Dental implant for fastening of a denture
Inventor: DOERING KARLI DR MED
IPC: A61C8/00
Filed: 1987-10-31
Abstract: The invention relates to a dental implant for fastening of a denture. The invention is applied in stomatology. The invention is suitable for patients who have lost individual maxillary or mandibular teeth and for free-end gaps in the mandible. The essence of the invention resides in the fact that a cap-shaped denture support non-positively connected to the basic body consists of a truncated conical member receiving the denture and of a concave neck member to be connected to the basic body of the implant. The truncated conical member adjoins the neck member directly or via a stepped shoulder. Several basic bodies of implants or complete implants are connected to form a block via a connecting bridge. The benefits of the implant system lie in the fact that is is suitable for replacing individual teeth and, when combined to blocks, is suitable for replacing groups of teeth. Because it is possible to combine different lengths of the basic bodies the individual anatomical situation in the jaw region can be taken into account. <IMAGE>

The contact rollers allow good current supply and an accurate central guiding of the electrode without the advance of the electrode being impaired.
Patent DE-3742191-A1 (DE)
Title: Dippable vehicle headlight (headlamp)
Inventor: WEIGEL MANFRED
IPC: F21V7/00
Filed: 1987-12-12
Abstract: The headlight has an incandescent lamp with an incandescent filament for main beam and an incandescent filament for dipped beam. The reflector has reflection regions which are in the shape of a paraboloid and have a common axis. The reflection region arranged above the reflector has a shorter focal length than the remaining reflection region of the reflector. Directly adjacent to the vertex opening, the reflection region arranged above the vertex opening has a section of area whose focal length is shorter than that of the remaining section of area of this reflection region. These two sections of area of the reflection region are connected by a coaxial section of area of the lateral surface of a conical frustum. The generating lines of the conical frustum are formed by the common tangents through the adjacent end points of the parabolic branches, produced in an axial longitudinal section, of both sections of area. In this case, the generating line of the conical frustum is so long that the focal point of the section of area having the shorter focal distance is arranged inside the incandescent filament for the main beam or, seen in the direction in which light exits, upstream of the incandescent filament for the main beam. The result is the provision of foreground (close-range) illumination over a wide area, in particular for vehicles used in construction and agriculture.

Title: Wheel suspension
Inventor: MUHR KARL-HEINZ DR ING
IPC: B60G15/07
Filed: 1987-12-22
Abstract: A helical compression spring (3) is illustrated and described, particularly for a wheel suspension having a spring strut connected to the body on the one hand and to the wheel on the other hand and possessing the helical compression spring (3) and a shock absorber and having a transverse link. When the helical compression spring (3) according to the invention is used in a wheel suspension, the transverse forces occurring on the piston rod of the shock absorber are reduced in that all the turns of the helical compression spring (3) have a bar diameter changing between a minimum value, a maximum value and again the minimum value. Because all the turns of the helical compression spring (3) have a bar diameter changing between the minimum value, a maximum value and again the minimum value, there are introduced transverse forces (Fx, Fy) and moments (Mo, Mu) which result in the line of action of spring force (9) no longer coinciding with the spring centre line (7). <IMAGE>

Title: Methods for the production, by genetic manipulation, of a recombinant enzymatically active HIV-specific protease and the precursor molecules of the group-specific antigens (gag) and of the polymerase (pol) and use of these products in mixtures for testing HIV protease-specific inhibitors
Inventor: WOLF HANS PROF DR DR
IPC: C12N9/50
Filed: 1988-01-07
Abstract: This invention comprises the simple and non-hazardous possibility of testing the activity of specific protease inhibitors, both in vitro and in vivo, with the aid of enzyme and substrate produced by genetic manipulation. This invention describes the production, by genetic manipulation, of polypeptide precursor molecules (gag precursor molecule and pol precursor molecule) as well as the expression of an enzymatically active HIV protease. The use of the said proteins in both in vitro mixtures (as protein extracts) and in vivo mixtures (expression in prokaryotic or eukaryotic cells) permits the effect of specific inhibitors on HIV protease to be determined in simple test mixtures. At the same time, the test mixtures described can be used to check the penetration of such substances into cells. The described test mixtures use exclusively HIV-authentic protein sequences. This makes it possible to avoid the elaborate and not entirely non-hazardous purification of corresponding proteins from virus-infected cell cultures or isolated virus particles.

Title: Method for producing a plastic layer
Inventor: OSTWALD ROBERT DR ING
IPC: C09D5/44
Filed: 1988-02-26
Abstract: A method for selectively producing plastic layers on metallic substrates is described which is based on electropolymerisation of acrylic derivatives by means of pulsating direct current. By virtue of a special finishing treatment (aftertreatment, secondary treatment) it is possible to ensure that even very thin layers having a thickness of less than 1  mu m are pore-free. They are therefore suitable, in particular, as low-loss anticorrosive layers for microwave components.
