Inventor: DIETRICH JOHANNES
IPC: F16H25/22
Filed: 1988-11-10
Abstract: A device for converting a rotary movement into an axial movement is provided in which a spindle (1) with an external profile, a nut (2) which surrounds this spindle, can rotate relative thereto and has an inner profile (20), and suitably profiled roller bodies (3), between the spindle and the nut, are provided. In this case, the roller bodies have two different profiles one of which produces an axial force-fit with respect to the profile on the spindle and the other produces a corresponding axial force-fit with respect to the profile on the inner side (20) of the nut. 
<??>The profile on the inner side (20) of the nut is preferably constructed in the form of relatively coarse grooves, of V-shaped cross-section, while a single-start fine thread is designed on the outer side of the spindle. On the outer circumference of the roller bodies (3) arranged between the spindle and nut there are provided, in alternating sections with respect to each of the coarse grooves, correspondingly coarse grooves (32), matching the inner side of the nut, and in each case a number of finely designed grooves (31) between them, which fine grooves (31) correspond to the single-start fine thread (10) on the spindle.

Abstract: In a spectrometer (1), a preparation (4) is irradiated with X-ray radiation. X-ray quanta emitted by the preparation (4) are converted after reflection by an analysis crystal (9) by a detection device (13) into pulse signals. In a pulse discrimination device (26), the pulse signals are discriminated and are recorded as single or multiple integrated pulse signals in a signal processing device (40) as numbers of pulse signals. After termination of the measurement, the numbers of pulse signalsare read out from the signal processing device (40) and an analysis on the numbers takes place by means of a data processing device (51). For example, the total number of detected quanta of monochromatic radiation may be determined.

Abstract: A sensing and adjustment assembly for a mirror (32) on automobiles has a sensor comprising an electronic oscil­lator which is associated with a mirror position indicator member. Movement and position of the mirror (32) is detected by the sensor. A driving arrangement responds to the sen­sor to move the mirror (32) to a preset position which position is stored in a computer memory. The oscillator (54, 55) can have a winding of spiral shape and the indicator (34, 36) can comprise material capable of absorbing electromagnetic energy, such as steel, and can be of substantially tapered shape such as substantially conical. The member can be moved through a center passageway for the winding. The oscillator can be a Colpitts or other type. A differential amplifier, a converter from A.C. to D.C., and another amplifier can be part of the sensor. A pair of sensors and indicators can be used in conjunction with the drive means to move the mirror in two planes. The mirror positions can be stored in computer memory in correlation with the selected seat positions of a plurality of passengers, and the computer connected with the assembly and seat system, so that when the seat is moved to a preset position, the mirror is also moved to a preset position that permits the passenger to have proper viewing through the mirror.

Abstract: An improved electrical connector for making electrical connections between electronic components. The improved electrical connector includes an insu­lating board interposed between metalized contact areas on the electronic components. The insulating board has openings at positions corresponding to the contact areas of the electronic components, with electrical connections between the contact areas established with conductive connector elements posi­tioned in the openings of the insulating board. The connector elements are preferably each formed from a strand of metal wire, each strand being wadded together to form a nearly cylindrical "button" of material having a density of between twenty and thirty percent. The improved electrical connector provides high density contact areas, easy engagement and disengagement of the electronic components, and minimum electrical resistance between the contact areas.

Abstract: Le palier à gaz (10) est conçu pour assurer une séparation instantannée de l'ordre de 5 à 10 micropouces au démarrage grâce à une entrée et activation régulées de particules de gaz moléculaire raréfié. Le palier possède deux faces opposées (13, 21) ayant des géométries correspondant précisément. Une surface possède des rainures (15) ayant des plats (16) formés entre les rainures (15) et destinées à fonctionnement hydrodynamique. L'autre surface (21) est lisse telle qu'un plan optiquement plat. Le décollage ou la levée s'effectue au moment du démarrage par l'intermédiaire de molécules de gaz excitées par friction qui augmentent de volume et obligent les faces du palier en rotation lente à se séparer. Un bord d'attaque à profil précis (17A) est formé sur chaque plat (16) qui supporte une pression de gaz moléculaire négative dans l'interface de palier à faible déplacement de manière à ne pas provoquer un refroidissemnt ou une compression injustifiée des molécules de gaz jusqu'à atteindre une vitesse correspondant au décollage du palier à gaz pressurisé normal, formant un écoulement de gaz comprimé non reglé et normal.

Abstract: A suction type road sweeping vehicle (10) generally has a self propelled chassis (11) with road wheels (12). Mounted on the chassis is an air tight container (14) for collecting dust etc. swept up by the vehicle. Dust etc. is sucked up into the container via pick up conduits (24) and nozzles (17), the suction being provided by a fan (16). When hydraulically driven brushes (18) and the like are used the hydraulic oil must be cooled. This is effected by introducing water into the conduits to mix with the cooling stream of air flowing into the container, separating the cooled water from the air and debris and utilising the cooled water to cool the hydraulic oil.

Abstract: A method of processing data for transmission from a transmitter T to a receiver R both of which are switchable between a compression mode in which the data stream is encoded or decoded with a data compression algorithm and a transparent mode in which the data stream is transmitted or received unencoded , comprising reading an input data stream at the transmitter T, encoding at least part of the input data stream with the data compression algorithm to form a compressed data stream, monitoring the efficiency of compression of the compressed data stream and controlling the switching of the mode of the transmitter T and receiver R so that the input data stream is transmitted efficiently. 
     In the transparent mode both the receiver and the transmitter check independently the efficiency of compression and switch to the compression mode if the transparent mode is determined to be inefficient. In the compression mode the transmitter T determines the efficiency of compression and transmits a control code to the receiver R, switching both the receiver and transmitter to the transparent mode if the compression mode is determined to be inefficient.
