Patent DE-4008104-A1 (DE)
Title: Faster composting appts. with self-circulating air flow - where warm air from reaction rises, cools and falls to base of container via tube, draws in water and flows through heap again
Inventor: WIENEKE FRANZ PROF DR ING
IPC: C05F17/00
Filed: 1990-03-14
Abstract: Process and appts. for composting biological materials. Heat produced by the reaction rises above the heap, is cooled and falls via a central or side channel to the heap base where it is drawn in again, thus forming a self-circulating air flow. Moisture is picked up during circulation and carried into the heap. Appts. comprises a closed, insulated container with a continuous, perforated central pipe in which a water container with an exposed water surface is suspended. An annular gap remains between the water container and central pipe for air circulation. USE/ADVANTAGE - Used for efficient composting with more rapid material breakdown.

Title: Filling element control for liquid filling machine - using multiplexer for level transducer signals to avoid rectification and integration
Inventor: PFEIFFER GERHARD DIPL ING
IPC: B67C3/28
Filed: 1990-04-14
Abstract: The method controls the filling element of a liquid filling machine with an electrical actuator (SM1-SMn) for each liquid valve . Transducers (SG1-SGn), associated with the actuators, generate signals corresp. to the levels below or at a defined fill level in the (1) containers being filled. The signals are multiplexed (8) before evaluation and used to control the valves. The evaluation electronics output signal is detected by the control electronics by sampling only during a predefined phase of the periodically varying transducer signals.

Title: Automatic laying support thread in lace - using separate control equipment to knit eyelets around support thread
Inventor: JONCKHEERE RAFAEL
IPC: D04B23/00
Filed: 1990-05-31
Abstract: Automatically knitting a support thread or cable into and out of eyelets in Raschel laceware, comprises feeding the thread in separately, at the same time as the warp threads, by means of a special guide which places the thread alternatively beneath and above the lace, when knitting the eyelets. The appts. is also claimed. The support thread is sepd. from the warp threads, at the front of the frame, and taken through a controlled guide tube. The knitting guides for the eyelet also take separate warp as these are controlled partly by the general guide rails, and partly by the control, so that an eyelet is knitted into the fabric. The guide lays the support thread or cable under the knit and over the knit alternatively at each eyelet construction. USE - The net material may be supported by the thread or cable during subsequent processing.

Title: Sheet metal interlock - is formed by bent hook and limit stop recess on sheet to lock folded and profiled tab on other sheet at corner joint
Inventor: WALLISCH HEINZ
IPC: B21D39/02
Filed: 1990-06-01
Abstract: The folded edge structure of sheet materials, to give a keyed interlock between them such as for assembling fan housings, has a fold (3) at the first sheet section (1) formed from a bent section (11) which projects inwards from the sheet level (4) to form a limit stop and then runs back to the upper limit line (8) of the sheet and moves along and parallel to this line (8) to end in a clamp hook (12) which is turned back at its lower level towards the limit projection (11). The sheet (2), at right angles to the first sheet (1), is bent inwards at the locking zone until it is close to the limit stop projection (11) of the first sheet on an inwards line (14), and is then angled outwards towards the limit line (9) of the second sheet (5) within the clamping hook (12) formed from the first sheet (1). The change in direction from within to a vertical line towards the first sheet (1) forms a limit stop (15) against the limit stop projection (11). The hook (12) at the end of the first section (1) therefore grips and holds the anchoring end (16) of the profiled length of the second section (5), between the clamping levels (12, 13) of the hook. These folded hook structures are formed at various points along the edges of the two sheets to be joined together. ADVANTAGE - The system gives a locked joint where two sheets meet, at the corners of the housing, without requiring welding or soldering or riveting to hold them together in a rigid housing.

Title: Interference voltage suppression system e.g. for vehicle electrical equipment - has operational equipment for interference voltage pulses, whole output activates operational circuit
Inventor: DIAMANTIDIS GEORG
IPC: H04B15/00
Filed: 1991-01-26
Abstract: The operational amplifier (2) amplifies the interference pulses, with its input forming the output of signals activating a circuit (3) consisting of several amplifiers and transistors and a capacitor. If a first amplifier is activated by an interference voltage signal, a transistor is blocked by reactivation of a second amplifier. Under control of another amplifier a second transistor is made conductive and closes the capacitor against earth. With the capacitor activated, a current rises in a choke and has an opposite valuation, thus equalising the interference voltage pulse at the choke output. USE/ADVANTAGE - For car telephones, car stereo systems, ships, trains etc., with improved interference voltage pulse suppression.

Title: Method for automatic adjustment of steel belt roller conveyor guides - using friction noise sensor, bandpass filtering and signal comparison with stored data for positioning motor control.
IPC: B21B39/14
Filed: 1991-12-06
Abstract: The method of adjusting the side constraints of a roller supported flat steel conveyor belt (1) propelled by a drive head (16) for the transport of hot materials involves using movable (11) edge-guides (3, 4) positioned by an electric motor. The contact noise caused by friction between the belt edges and the guides (3, 4) is picked up by a sensor (5) and its signals are filtered within the range 2.5 kHz to 7.5 kHz for comparison with predetermined stored rollers. Excessive signal amplitudes indicate excess pressure on the guides (3, 4), and the side-thrust is then relaxed via the positioning motor. USE/ADVANTAGE - Ensures automatically controlled pressure and minimum wear on edge-guides. Bandpass filtering eliminates sensor response to random noise signals to facilitate comparison with reference data.
