Title: Treatment of condensate in air compressor units and esp. transportable compressors - with condensate absorbed into cylindrical or flat filter elements and water evaporated by air heated by passing over compressor housing
IPC: B01D45/08
Filed: 1992-08-26
Abstract: A compressor unit has a compressor (13) and a condensate filter (14) which separates water and oil from the compressed gas. The novel feature is that a filter (16) containing a filtration material (2) is arranged so that an air stream (3) which has been heated by passing over the compressor evaporates the water in the filtrate from the condensate filter (14). Pref the filter material consists (2) of a number of parallel filter elements (4) located approximately perpendicular to the air flow (3). These elements are held at a required distance from each other by a support consisting of one or more perforated plates. The elements are made up of spirally wound filter material surrounding hollow central spaces. USE/ADVANTAGE - In air compressors, and especially transportable compressor units such as are used for supplying air for divers. The oil/water condensate separated from the compressed air is treated in such a way that it can be disposed of more easily and with less risk of damage to the environment.

Title: Motor vehicle radio identification system
Inventor: SCHUPPANG GOTTFRIED
IPC: G07C5/00
Filed: 1993-03-17
Abstract: This system makes it possible reliably to identify, in particular lost motor vehicles, rapidly and over long distances.

Patent DE-4318778-A1 (DE)
Title: Turning gear
Inventor: GAUCHEL MANFRED DIPL ING
IPC: F16H37/12
Filed: 1993-06-05
Abstract: The invention relates to a turning gear with a turning shaft which can be driven by way of a positive connection by means of a hydraulically or pneumatically actuated piston. The object on which the invention is based is to provide a turning gear which provides short turning times and a torque which increases towards the points at which the motion is reversed. The object is achieved by virtue of the fact that the turning shaft 1 has connected to its output an additional gear which transforms a constant angular velocity of the turning shaft into an angular velocity of the final turning shaft 2 which varies from zero to zero via a maximum between the points at which the motion is reversed. In this way, gentle starting and deceleration of the turning movement is achieved, making possible short turning times or high turning masses. The high turning torque in the region of the points of reversal of the turning movement is ideal for the actuation of flaps. <IMAGE>

Title: Power factor correction circuit with rectifier - has input terminal for downwards divided, rectified AC signal, and voltage sensor
Inventor: CHOI NAK-CHOON
IPC: H02M7/06
Filed: 1993-06-29
Abstract: The rectifier (103) treats the AC input signal, and an inductivity (111) is incorporated between a switch (113) and the rectifier. An input terminal (124) receives the downwards divided, rectified AC signal. A voltage sensor generates an output voltage fault signal, corresp. to a deviation of rectifier output signal from a reference. A combination of the divided signal and the fault signal generates a sinusoidal reference signal. A current indicator signal from a sensor (114) transmits an inductivity charging signal. Second such signal is generated by a second current sensor (110). The generation of all relevant signals is controlled by current generating controls to approximate the inductivity current to the sinusoidal waveform of rectified input voltage. USE/ADVANTAGE - For attaining power factor approaching unity, with wide input range, and reduction of dead time.

Title: Transport system for production installations
Inventor: SIMONIS GERHARD DIPL ING
IPC: B65G21/02
Filed: 1993-10-15
Abstract: In transport systems of this type, it has been possible to fasten the elements for moving a workpiece and the elements for positioning it to the carrying parts of the transport system from below only. Furthermore, a workpiece carrier moved by an accumulating roller chain (5) has no lateral guidance, so that the movement drifting away from the direction of movement of the accumulating roller chain has to be continually checked and, where appropriate, corrected. To eliminate these disadvantages, the longitudinal profiles (1) have a bearing surface (4) on their sides facing one another. A cover (7) engaging over the free space (6) between the longitudinal profiles (1) is connected easily releasibly to the longitudinal profiles (1). The top side of the cover (7) is provided with a guide groove (13) extending parallel to the longitudinal profiles (1). <IMAGE>

Title: Position-determining and location-determining device of optical type
Inventor: SUZUKI TORU
IPC: G01S3/783
Filed: 1994-03-11
Abstract: A position-determining and location-determining device of optical type comprises at least two light sources. The two light sources are arranged at a prescribed distance from one another. The two light sources are changed over alternately. A light-receiving element picks up light from each of the light sources and determines at least one two-dimensional angle with respect to each light source. The location and position of the light-receiving element is calculated on the basis of the prescribed distance given the two-dimensional angles. An angle-determining device comprises a photodetector which has at least two light-receiving regions. At least one light-interrupting plate is arranged between the two light-receiving regions, specifically in a vertical fashion with respect to the regions receiving the light. The angle of incidence of the light of one light source, which falls onto the photodetector, is calculated on the basis of the light quantities which are picked up on each of the light-receiving regions. The light-interrupting plate can be produced from a light-absorbing material, or can be produced in the form of a dihedral mirror.
