Title: Separating plastics from mixtures of waste materials - by irradiating with UV radiation then analysing reflected radiation to identify plastics present
Inventor: MINDERMANN KURT-HENRY DR
IPC: B07C5/342
Filed: 1992-10-30
Abstract: Process for the separation of different plastics materials and opt. other waste materials.

Title: Process and apparatus for washing tubular membranes for liquid treatment units
Inventor: OBERDORFER-BOEGEL RAINER
IPC: B01D65/06
Filed: 1993-04-14
Abstract: The present invention relates to a process and an apparatus for washing tubular membranes for liquid treatment units. In order to remove in a simple and operationally reliable manner the dirt particles adhering to the tubular membrane (3) without the risk of damaging the tubular membrane (3), according to the invention, by means of a feed pump controlled in a frequency-modulated manner, a hydrodynamic washing of the tubular membrane is achieved by a surfactant solution being introduced into the tubular membrane instead of and in the same direction as the waste water flow (4), the volumetric flow rate of the surfactant solution being controlled by the feed pump in such a manner that periodically either a laminar flow or a turbulent flow is established at the inner surface of the tubular membrane (3). The dirt particle covering layers are effectively gradually detached from the tubular membrane by the different flow conditions during this washing operation. <IMAGE>

Title: Flexible shaft coupling
Inventor: SCHAEFER WILHELM F DR
IPC: F16D3/77
Filed: 1993-04-16
Abstract: A flexible shaft coupling (1) for torque transmission, particularly for ships' drives and the like, has a flexible diaphragm disc (6) which has a plurality of rubber bushes (7) distributed around its circumference. A coupling disc (4) carries a plurality of axially parallel driver pins (5) at its circumference. Each rubber bush (7) is carried in axially displaceable fashion on a driver pin (5). Axial displacements and angular displacements of the two shafts (2, 3) connected initially cause a deformation of the diaphragm disc (6) and, in the case of greater displacements, a sliding movement of the rubber bushes (7) on the driver pins (5). Overstressing of the shaft coupling is in this way avoided. <IMAGE>

Title: Servo driven boot lock for motor vehicle - has hinged catch plate to grip door catch and servo drive to pull door shut
Inventor: SHIMADA JUNICHI
IPC: E05B65/12
Filed: 1993-06-29
Abstract: The door catch (12) is dropped into the open jaw of the catch and displaces a hinged catch plate to secure the catch. The pivot action of the catch plate activates a servo drive to pull the door down onto the seals and secure the lock. The servo motor is driven in the opposite direction to release the lock. A failsafe system protects against trapping obstruction between the door and the seal. The failsafe protection causes the locking catches to be displaced. If the lock is not moved to the end position within a set time interval the failsafe protection reverses the motor drive and returns the catch to the raised position from where the door can be opened by hand, to remove the obstruction. ADVANTAGE - Simple locking mechanism, failsafe protection.

Title: Production process of noncombustible elements from reinforced Sorel cement (oxychloride or oxysulphate cement)
Inventor: IVANKOVIC JOSIP
IPC: C04B28/30
Filed: 1993-07-05
Abstract: Process for producing noncombustible elements from reinforced Sorel cement is a simple and economical solution of the production process without use of energy, with no materials hazardous to health being formed in production and in any case of fire. The raw materials are inorganic and economical and the binding into a hard mass is hydraulic. By means of noncombustible insulation materials, it is easy to produce very compact layer composites which have a flat, straight or another surface and shape. If combustible insulation boards (such as PUR, PIR, Styropor (foamed polystyrene), cellulose, etc.) are used, layer composites having the exterior surfaces protected against fire are obtained.

Title: Method and device for adjusting beam guidance and beam shaping and for dimensioning optics, in particular in laser beam installations
Inventor: DU KEMING DR
IPC: B23K26/70
Filed: 1993-07-07
Abstract: The invention relates to a method and device for adjusting beam guidance and beam shaping and for dimensioning optics, in particular in laser beam installations. In the method according to the invention, to assess the beam course, beams or quasibeams made up of beams running in parallel fashion are generated by means of a radiation-emitting diode array or by beam splitting of the radiation from a light source. The beam splitting is carried out by means of plane-parallel plates or retroreflectors, that is to say without additional lenses, and thus without distortion of the beam path. The parallel-aligned beams pass through the optical components of the optical system and are finally incident on an optical screen or a location-sensitive radiation unit. From the deviation of the incident beams from predetermined desired values, a measure is determined of the quality of the optics or of their adjustment. If necessary, the optical system is re-adjusted manually or via an evaluation and control unit. A preferred method consists in temporarily blanking out individual or several parallel-aligned beams from the bundle of radiation. In comparison with adjustment using a processing laser or expanded adjustment lasers, the method according to the invention is distinctly less complicated and also has higher adjustment accuracy. The advantage of the invention also consists in the fact that the device which is based thereon ... Original abstract incomplete.

IPC: H04B7/08
Filed: 1994-02-05
Abstract: The circuitry is for a multiple antenna scanning diversity system for vehicles, with an antenna arrangement with a controllable switch unit (11).
