Title: Kinetic transformer
Inventor: SCHOTTELIUS HORST-ULF
IPC: F16H19/00
Filed: 1987-09-03
Abstract: A kinetic transformer (11), in particular for piezoelectric-controlled laser precision controllers, is to be designed in such a way that it can be set up as far as possible with the use of standardised parts for machine building which can be obtained inexpensively, and can be used in both transformation directions. It is also to permit control or scanning (sensing) movements, which are to be capable of being carried out reproducibly, to be adaptively or reversibly transformed in multiple stages as far as into the micrometre range and nanometre range without a high additional design outlay, depending on the application envisaged. For this purpose, a rolling-element cage (13), which is arranged in a slip free fashion between a support element (12) and a moving element (14), or the moving element (14) which is supported by the rolling elements (15) of the cage, is constructed as drive element (21) or as driven (output) element (24). Transmission of motion is provided depending on whether the input variable acts directly on the rolling-element cage (13) or, rather, indirectly thereon, specifically via its rolling elements (15) by means of the moving element (14). A multistage transformation of movement results when the moving element (14) supported by the rolling elements (15) is, for its part, again constructed as a cage (13) for rolling elements which are held on the same support element (12) and then for their part again support a moving element (14). <IMAGE>

Title: Method for preparing a monocrystalline layer, consisting of a first semiconducting material, on a substrate composed of a different-type second semiconducting material, and use of the arrangement for fabricating optoelectronic integrated circuits
Inventor: WINSTEL GUENTER DR RER NAT
IPC: H01L21/20
Filed: 1988-05-11
Abstract: In order to prepare a monocrystallline layer (3), consisting of a first semiconducting material, e.g. silicon, on a substrate (1) of a different type of second semiconductor material, e.g. of an AIIIBV compound, the layer (3) of the first semiconductor material is first applied in amorphous or polycrystalline form to the substrate (1) and is then transformed, with the aid of a lateral recrystallisation process, e.g. by laser light (4), into a monocrystalline layer (3). In this process, the substrate (1) may contain patterns of insulating material (2), e.g. insulation oxides (2) for separating (segregating) the active components. The method is suitable for fabricating optoelectronic integrated circuits on the basis of AIIIBV compounds in combination with silicon. <IMAGE>
Patent DE-3820720-A1 (DE)
Title: Twin-gyro compass with precisely functioning oscillation damping
Inventor: CHRISTOPH PETER DR RER NAT
IPC: G01C19/16
Filed: 1988-06-18
Abstract: The meridian oscillations of the gyrosphere of the twin-gyro compass and the internal oscillations of the gyro assembly are caused to decay by means of temporarily strongly delayed rotational moments about the two horizontal axes of the gyrosphere. Until now, a ring vessel half-filled with viscous oil has been used for this purpose in all twin-gyro compass systems. The regular behaviour required for the rotational moments from the theoretical function concept is, however, only approximated by the ring vessel. In the first place, these disturbances are produced by adhesive forces of the free oil surfaces on the vessel walls. Their effect is similar to that of Coulomb solid friction. The disturbed damping moments cannot only be detected in the testing station laboratory. At sea, they especially limit the quality of the course correction if the alterations of the state variables of the gyro system, activated by manoeuvring but calculable, are continuously calculated by a computer on the basis of the mathematical model and the azimuthal deflection of the gyrosphere out of the meridian plane is used in this case for the correction of the course display. To overcome the damping moment disturbances and as a precondition for the full efficiency of the course correction procedure, a damping device for both groups of oscillations is specified according to the invention, which is free of disturbances of all types and satisfies the required regularities of behaviour in the highest degree: a solid-mass pendulum, which ...

Patent DE-3827397-A1 (DE)
Title: Propellant charge powder
Inventor: REINELT KARLHEINZ DIPL ING
IPC: F42B5/16
Filed: 1988-08-12
Abstract: An internal-ballistic increase in the performance of propellant charges can be obtained by increasing the loading density by means of recompaction or pressing of the propellant charge powder. However, this requires a further fabrication step and corresponding compaction devices. In addition, single-base powders cannot be pressed at all, since they break under a corresponding stress. The present invention indicates a simple process for increasing the loading density of powder charge assemblies, the powder not being pressed and the process also being applicable to single-base nitrocellulose powders. According to the invention, this is achieved when the propellant charge powder consists of at least two different types of hole powders with a different number of holes and, in this case, the voids between the multi-hole powder (26) are filled by 1-hole powder (24) or ball powder of the same wall thickness as preset for the multi-hole powder. <IMAGE>

Title: Luminaire having a plurality of light sources of low-voltage halogen lamps and an AC power controller
Inventor: STUMPMEIER FRITZ DIPL ING
IPC: H05B39/10
Filed: 1988-08-24
Abstract: A luminaire which is fitted with between 2 and 20 low-voltage lamps connected in series and in which furthermore a specific AC power controller or an AC power controller with dimmer is connected in series. The maximum output voltage of this AC power controller has to be matched to the respective number of lamps or to the sum of the voltage of these lamps. This AC power controller can have two functions and limit the voltage and additionally control the brightness in the dimmer function. In this way, each luminaire which has only two lamps or any number of between 2 and 20 lamps can be controlled in a transformer-free manner. In a luminaire having a relatively large number of lamps, to detect a failed lamp, which is optically not possible in the case of halogen lamps, provision can be optionally made for an optical signal transmitter (glow-discharge lamp) or a light-emitting diode or even an electronic environment of the failed lamp by means of an NTC conductor. All three systems are in each case connected in parallel to each lamp.
Patent DE-3829018-A1 (DE)
Title: Method and device for composting waste
Inventor: HOFMANN HERMANN
IPC: C05F17/00
Filed: 1988-08-26
Abstract: A method serves for the composting of organic substances, preferably domestic refuse or waste which is similar to the latter. The organic substances (2) are introduced into a container (21, 29) which is preferably enclosed. Feeding air causes the easily biodegradable components of the organic substances (2) to undergo biological transformation. Composting is halted by means of drying when the easily biodegradable components have been broken down. In order to simplify and improve such a method, the weight of the organic substances (2) is repeatedly or continuously measured and composting is halted by drying when the weight of the organic substances (2) falls below a predetermined value. The device for implementing this method is composed of a container (21, 29) which is preferably enclosed and has floor plates (1), which are permeable to air, and air supply ducts (6) which are provided beneath the said plates (1). Weight-measuring appliances are connected to the floor plates (1) (Fig. 1). <IMAGE>
