Title: Roller shutter lock mechanism - is released by pushbutton on outside of shutter
Inventor: BADER JOACHIM DIPL ING
IPC: E06B9/17
Filed: 1991-08-20
Abstract: The roller shutter has a flat bar (5) attached by screws to its lowest slat (3). The bar (5) has upward projecting hooks (7) which engage lugs (8) which project endwise from a plate (6). The plate (6) is supported in a vertical position by straps (9) fastened to a bar (10) attached to the adjacent upper slat (4). The roller shutter is locked by a bracket (12) which engages a tongue (14) which projects from the plate (6). A leaf spring (16) can be positioned so that it guides the tongue clear of the bracket (12) and so allows the shutter to be opened.

Patent DE-4131278-A1 (DE)
Inventor: SCHANDL HARTMUT DIPL ING
IPC: H02P5/56
Filed: 1991-09-20
Abstract: Integrated motor circuits for controlling electronically commutated motors driving head drums are known which include means of obtaining tacho-signals for the motor speed control and means of obtaining control signals for commuting the motor phase belts. These signals are obtained by commutation by the detection and evaluation of the transitions through zero of the induced countervoltages when the phase belts are switched off. However, the precision of the motor drive is determined by the manufacturing tolerances on the motor. For high-precision motor drives in recording and playback instruments, therefore, a phase regulation derived from markings on the rotating parts is also used. The aim is to reduce the complication of phase detection of the read/write heads fitted at the periphery of a rotating head drum in a circuit for regulating the head drum and tape drive. In an electronically commutated head drum motor (3) fitted with a motor control circuit (32) generating commutation control and tacho-signals from the commutation of the phase belts (X, Y, Z) of the motor (3), in order to detect the phase of the read/write heads (K1, K2) arranged at the periphery of the rotating head drum (1), one of the phase belts (X, Y, Z) is used by deriving from the commutation of this phase belt a commutation signal (I) which is placed in a relationship with the reference signal (20) of a signal track to be recorded or played back. Especially for video recorders and camcorders.

Title: Buoyancy-conversion system into rotary movement - uses floats travelling immersed along half circular path in vertical plane and deflected from inner to outer radius
Inventor: STEINWELLER GERT
IPC: F03B17/04
Filed: 1992-03-20
Abstract: The system uses floats (5) travelling immersed along half of a circular path in a vertical plane. In the process, their centres of gravity are deflected from and inner to an outer radius, typically at the lowermost point. The floats can work in guide rails (9) free of load, and can return to the inner radius once they are no longer immersed, the torque exerted by them when deflected exceeding that from those no deflected. They can be mounted on a semi-immersed rotor on a central shaft (1) and can have wheels on their ends working against a deflecting immersed guide rail (9).

Title: Garment has sensors coming into contact with body parts - where values received by sensors are led to central collector
Inventor: MOSER MAXIMILIAN DR
IPC: A61B5/0408
Filed: 1992-05-03
Abstract: A garment features sensors which can be brought into contact with different body parts. The sensors receive and conduct several biophysical functional values from the skin surface in addition to receiving and conducting several measuring values which are produced on measuring devices through the effect of body functions or actions. During a specific period of time, the values are led to a central collecting unit (11) which is located on a garment part (10) or is separate from the garment. This unit is connected to a storage or recording unit. ADVANTAGE - The method permits a simple handling of the sensors and the associated electrical connections for the measuring, recording and possible evaluation of complex body functions.
Patent DE-4217764-A1 (DE)
Title: Sorting process for sepg. polyethylene@ from polypropylene@ - by heating the water particles with polyethylene shrinks and forms heavier fraction whilst polypropylene@ can then be removed by air elutriation
Inventor: KANIUT PETER DIPL ING
IPC: B03B1/02
Filed: 1992-05-29
Abstract: In a sortation process for separating pieces of polypropylene from those of polyethylene small pieces of the two polymers are mixed and the mixture is heated until they contract or shrink together and those of the two polymers are then separated from each other. ADVANTAGE - The polyethylene particles shrink considerably more than those of polypropylene. This principle allows the two polymers to be separated, whereas they cannot be differentiated visually. The method produces pure polymers. It is suitable for use industrially and can be applied to domestic waste plastics (which commonly consist of the two polymers mentioned, e.g., in wrapping films). In an example, the two polymers (e.g., as bags, films, etc., with or without being disintegrated first, are fed to a cutter/compressor which has revolving cutters and which reduces them to, e.g., thumbnail size. This action has a heating effect, enough to raise the temp. of the mixture to above their softening points.

Patent DE-4313715-A1 (DE)
Inventor: ITTMANN GUENTER
IPC: C08F2/44
Filed: 1993-04-27
Abstract: The invention relates to a process for preparing filled, expanded polymer materials based on polymethacrylate. An initial solution VL consisting of 5 to 70 parts by weight of methylmethacrylate and 1 to 15 parts by weight of polymethylmethacrylate prepolymer PP is prepared into which a particle-like inorganic filler FS in amounts of 30 to 80 wt.% based on the resultant suspension is introduced, while stirring rapidly, thereby forming a suspension. Gaseous or solid carbonic acid, in fine distribution, is uniformly introduced into the initial solution or suspension, whereupon, as a result of external heating or the heat effect of the polymerisation process, preferably initiated by the Redox initiator, the carbon dioxide is expelled while the polymerisation takes place. At the end of the polymerisation, removal from the mould can be effected.
