Patent DE-3844330-A1 (DE)
Title: Wheel rim with cover for a motor vehicle
Inventor: THONI LUDWIG
IPC: B60B7/14
Filed: 1988-12-30
Abstract: The invention relates to a wheel rim with cover over its screw connections to the wheel axles. In the simplest case, it has on the visible side only one hole which is assigned a pocket on the inside, in which pocket a screw is located and guided. The pocket is surrounded by a securing ring. In particular, hexagon socket screws with an uneven number of edges and changing key widths are proposed which make it difficult to steal the wheels.

Title: Flexible supply line
Inventor: GRZYWOK WILHELM
IPC: A61G15/16
Filed: 1989-01-14
Abstract: The invention relates to flexible supply lines for the supply of dental instruments and for use with return motion devices for the lines. At the end near the device the lines are provided with connecting fitting. These supply lines are to be designed in such a way that loads on the connecting fitting are ruled out and that the hose pipes arranged in the lines are protected from extension and squeezing. To achieve this the invention proposes that the flexible supply line be equipped with a strain relief which comprises a tensile connection between the instrument and a tension rod. The tensile connection is rigid in the longitudinal direction and the tension rod can be positively connected to the device independently of the connecting fitting. <IMAGE>

Title: Device to generate a specified pulse sequence
Inventor: NETT ANTON
IPC: G06F1/025
Filed: 1989-03-23
Abstract: To form a device, with a simple structure and high working speed, to generate a specified pulse sequence, a first register 3 and a second register 4 are connected to the output 2 of an EPROM 1. The output 5 of the first register 3 is fed back to address lines of EPROM 1. The clock signal of a clock generator 7 is applied to another address line 6, and also goes to the clock connection 10 of the second register 4, and, via an inverter 12, to the clock connection 9 of the first register 3. The output signal of the EPROM 1 is thus transmitted alternately as a new address part into the first register 3, or as an information value which represents a pulse amplitude into the second register 4, so that a pulse sequence with the stored pulse amplitudes is available at output 15 of the second register 4. (Fig. 1). <IMAGE>

Patent DE-3934220-A1 (DE)
Inventor: LIEBSCHER WOLFGANG DIPL CHEM D
IPC: G06F17/30
Filed: 1989-10-13
Abstract: The invention relates to the automatic formation of the systematic name of a chemical compound or a part thereof directly from its structural formula or conversely the structural formula or a part thereof from a name for a chemical compound, by use of a computer. In the first case the structural formula is analyzed into structural elements in a computer of a single- or multi-user system. The elements are designated by standardized terms (morphemes), which are assembled according to a formalism to systematic names. In the converse case, the name is analyzed into standardized part-names (morphemes) in the computer. The part-names are expressed by corresponding structural elements and assembled according to a formalism to the structural formula (whole formula). The outputting of the systematic name or the formula follows alone or together with other information on the screen or via printer/plotter or other recording medium. The process can be used alone or in industry and commerce, production, research and teaching. Previously known processes require the representation of the chemical constitution (name or formula) in matrix form as an intermediate step. <IMAGE>

Title: Pharmaceutical formulation of sparingly soluble active ingredients - prepd. by coating particulate active ingredient with starch, obtd. by retrogradation so that the active ingredient do not become phagocytic
Inventor: STEFFENS KLAUS-JUERGEN PROF DR
IPC: A61K9/50
Filed: 1990-03-20
Abstract: A pharmaceutical prepn (I) which is not phagocyted and which can be used for parenteral or mucous membrane application of sparingly soluble active ingredients consists of a dispose solid/liq. system with max. particle size of the active ingredient 3 micron. These particles have a coating of starch, starch components or starch derivs obtd. by retrogradation. USE/ADVANTAGE - (I) can be used with cytostatics, antibiotics, heart/circulation agents or spironolactone as the active ingredient. The small particles of active ingredient can be completely enclosed by the aggregates produced by the retrogradation, in comparison to larger particles, where the coating is not uniform and has holes, thus giving rise to some aggregates which contain no active ingredient nucleus. The body is not able to identify the solid active ingredient particles as foreign, and they are thus not phagocyted and eliminated from the system. The coating is completely biologically acceptable.
