Title: Two-stage compacting process for sorted industrial waste - involves collecting waste at point of production in separate containers which are wheeled into press and form part of compression chamber
Inventor: TENBRINCK GEORG
IPC: B65F9/00
Filed: 1992-03-28
Abstract: Different types of waste such as plastics material are sorted into separate containers (2) which are preferably placed close by the process where the waste is produced. A filled container is pushed into the press (1) through an opening in the side. An hydraulically driven ram plate (10) compresses the waste from above in the first compacting stage of the process. Next, through uncovered openings (28,29) in the sides of the container (2), a second hydraulically driven ram plate (15) advances and pushes the partly compacted bale of waste into a compression chamber (36). As the ram plate continues to advance the waste is further compressed in the final compression stage of the process. When the ram plate is withdrawn the fully compacted bale can be removed and the process repeated on the next filled container. USE/ADVANTAGE - Easy segregation of different types of waste.

Patent DE-4237759-A1 (DE)
Inventor: SCHACHT PAUL
IPC: A47B31/02
Filed: 1992-11-09
Abstract: The invention concerns a rosting and cooking device which can be designed as a table for social cooking and eating, with a foot, a leg and a metal table top whose edge is surrounded by a closed metal extrusion and on whose underside is located a device designed to heat the central zone of the table top. The leg is fixed to the table top outside the zone in which the heating device is fitted. Ideal conditions are created for the operation of the device by virtue of the fact that thermal expansion of the table top produces a depression in the central zone of the table top and, when the device is designed as a table, the unheated edge zones of the table top can be used for eating, leaving an intermediate zone available for keeping food warm.

Patent DE-4316320-A1 (DE)
Inventor: SCHUTTE RUDIGER DR
IPC: C01B15/12
Filed: 1993-05-15
Abstract: The invention relates to an improved process for producing sodium perborate monohydrate by dehydration of sodium perborate tetrahydrate in a fluidised bed by heated air. According to the invention, contact surfaces are arranged within the fluidised bed, the total area of which contact surfaces constitutes 1 - 500 times the area of the gas distribution plate of the fluidised bed. The contact surfaces are expediently designed as heat exchangers, the surface temperature of which is adjusted to 90 to 110@C. The process leads to a sodium perborate monohydrate having particularly high resistance to abrasion; at the same time the energy requirement is lower than in known processes.

Title: Ultraviolet suction bell disinfection apparatus
Inventor: UEBERALL PETER
IPC: A61L2/10
Filed: 1993-06-15
Abstract: The invention permits a particularly inexpensive and readily maintained chemical-free disinfection of circulated waters by means of ultraviolet radiation, such as in the troughs of air scrubbers. Instead of the UV disinfection apparatuses conventional there hitherto which uninterruptedly treat in a by-pass a part-stream from the air scrubber trough and must be mounted outside the wet zone, according to the teaching of the invention, the entire circulated stream of the air scrubber pump is treated within the wet zone via a particularly simply designed UV suction bell disinfection apparatus having submerged emitters which lies in the air scrubber trough and is connected to the suction nozzle of the air scrubber pump. The UV dose can be kept small in this process, because the water of the trough is circulated at least three to six times per hour and it is sufficient if the bacterial count is reduced by at most one power of ten per cycle. In the course of one hour, repeated treatment thus decimates even relatively high cell counts to permissible values. Increases in microbial contamination after relatively long operating pauses are worked off by running the air scrubber pump before switching on the air scrubber fan. In short pauses, the renewed increase in microbial contamination is only small.

Title: Circuit for safeguarding the setting-up operation in the case of a machine tool or in the case of a robot
Inventor: SCHNEIDER WOLFGANG DIPL ING
IPC: G05B19/4063
Filed: 1993-06-18
Abstract: It is necessary to undertake safety measures to ensure that operators cannot be endangered during the setting-up operation in the case of a machine tool (WM) or in the case of a robot. In the circuit according to the invention, monitoring of the speed of possibly dangerous axes is provided for this purpose.

The comparators (V2, V3) provided for this purpose then act on safety relays (I, II) whose positively driven (positive-action) contacts (I1, I2, II1, II2) are arranged in the emergency stop (stopping) circuit of the machine tool (WM) or of the robot. <IMAGE>
Patent DE-4331150-A1 (DE)
Title: Electronic immobiliser
Inventor: SCHUBERT ROLAND
IPC: B60R25/04
Filed: 1993-09-14
Abstract: The invention relates to an electronic immobiliser according to the features of the preamble, preferably for use in passenger cars. Known immobilisers are for the most part not automatically self-arming. They operate for example by using a code or a magnetic key and are technically relatively complex. With the invention, the intention is to provide an electronic immobiliser which is automatically self- arming and has a simple technical design. For this purpose, the arming of the electronic immobiliser takes place automatically when the ignition is switched off and uses a suitable electric circuit. The immobiliser is not activated until the ignition is switched on and the supply current to the solenoid switch of the starter of the motor and/or the ignition and/or the supply of fuel is interrupted. By activating, by means of an activation element (2), a sensor (1) which is arranged at any desired point in the vehicle, the immobiliser is deactivated and the supply of current to the solenoid switch of the starter of the engine and/or the ignition and/or the supply of fuel is enabled again and the vehicle can be started. <IMAGE>

Patent DE-4333465-A1 (DE)
Title: Control circuit having a number of sensors
Inventor: GLEIM GUENTER DIPL ING
IPC: H03K5/08
Filed: 1993-09-30
Abstract: To control a motor by means of sensors, for example for controlling the speed of and/or commutating a motor, it is known to allocate a number of sensors to the motor which generate a number of similar, mutually phase-shifted sensor signals indicating the rotor position. From the signals, control signals for the commutation and/or speed control are obtained in comparators such as, for example, differential amplifiers. In practice, disturbances which, for example, come from the motor coils and influence the analysis are superimposed on the signals at the outputs of the sensors. It is the object to construct a circuit of this type in such a manner that it is capable of suppressing disturbances even when the motor is standing still. According to the invention, a combination of two mutually phase-shifted sensor signals of separate sensors (H1/H2, H2/H3, H3/H1) is in each case applied to one input of a comparator (K1, K2, K3). Outputs of separate sensors are in each case preferably directly connected to one another. By combining mutually phase-shifted sensor signals, disturbances or interference signals reaching the sensors are compensated for. Especially intended for controlling the speed of or commutating a capstan motor in a video recorder. <IMAGE>
