Title: Filling exhausted potassium mine cavities with dry wastes - pretreated with suspension or soln. of salt wastes
Inventor: SILL FRIEDRICH DIPL ING
IPC: E21F15/00
Filed: 1989-09-26
Abstract: To minimise shifting of upper strata, cavities formed by mining, esp. in potash mines, are made resistant to collapse by introducing a filling based on fillers with fine or very fine particle size, mixed with a suspension of soln. (satd.  or unsatd.) of salt. The filling base may derive from coal-mining or residues from power stations or other combustion processes, in any case having a low initial water content. Salt residues may also be used as part of the filling base, and a binder may be added, pref. of slow acting type pref. proportions are established by preliminary laboratory testing. The final filling prod is pumped into the cavities pref. with the base already present. ADVANTAGE - Provides useful effect while economically disposing of different types of low-value waste.
Patent DE-3933282-A1 (DE)
Title: Transmission system - engages between conveyor and lift to drive latter
Inventor: AHOKAS KALEVI
IPC: B63B27/22
Filed: 1989-10-05
Abstract: The system transmits power to a movable conveyor, e.g the luggate lift (2) in a ship.  When loading, a conveyor (1) delivers the luggage through a loading hatch (20) in the ship to the lift, it being transported the opposite way when unloading. In both cases, a transmission mechanism (3) is engaged, so as to deliver power from the conveyor to the lift.  This can be done by pulleys (4,5) on conveyor and lift, and an intermediate belt (6). The latter runs round four guide rollers forming a parallelogram. The necessary friction between pulleys and belt is generated by turning the parallelogram so that its width alters. ADVANTAGE - Simplicity, reliability and low cost.

This conical element has external splines which engage matching splines in the upper end of the upper housing. The lower housing is fixed to the doorpost and the upper housing is fixed to the door. A torsional stress is applied to the torsion bar (1) through the conical element (5) when it is vertically above the upper housing. USE - Door closing spring.
Patent DE-3935434-A1 (DE)
Inventor: WOLTERS HERMANN
IPC: B21B37/00
Filed: 1989-10-25
Abstract: In the process for controlling the tape thickness it has been found that the complex roll eccentricities produced by the superimposition of several interfering influences are not adequately compensated for by the control methods which have hitherto become known. To be able to compensate for even complex roll eccentricities, it is proposed to determine the transfer function of the fault signal embodying the roll eccentricity and to derive from this transfer function controller parameters on the basis of which roll eccentricity compensation signals can be calculated. Using this means, the roll eccentricities are compensated for in accordance with the principle of adaptive control.

Title: Piston IC engine operating system - uses internal ribs in nozzle and pipe downstream
Inventor: LEISTRITZ HANS KARL DR
IPC: F01N3/28
Filed: 1989-12-05
Abstract: The operating system is for a normally-aspirated piston engine with thrust nozzle, oblong pipe.  A final silencer unit reflects the shock-waves.

Title: Sensor head cleaner - has brush mechanism in addition to aerodynamic means to remove stubborn deposits
Inventor: RAASCH HANS
IPC: D01H11/00
Filed: 1990-01-18
Abstract: A process for cleaning the passage of a sensor head which is employed to assess the yarn passing through it without making contact, and the process is carried out when there is no yarn present, by means of a mechanical method to clean the head, with apparatus which is installed in a service unit. The appts. is also claimed. Pref. on a rotor spinning frame a service unit passes along the front, and at certain intervals, or when there is a broken end to be repaired, the yarn is not present in the sensor head, so that the revolving brush may be advanced by the mechanism in the unit. The brush is designed to be suitable for the type of sensor head employed. An airjet is used to assist the brush, and at the same time a vacuum tube extracts the dirt. The requirement and timing of the cleaning operation, as well as the periodic interval, is controlled in the electronic circuit, and on withdrawal of the brush, a test is made of the sensor circuit to ensure it is working satisfactorily, otherwise the unit is stopped or an alarm indicated. In addition to rotor spinning frames, the equipment may also be employed on airjet or friction spinning units and winders.

Title: Sewing machine - has non-driven feed rollers with pneumatic direction guide control
Inventor: KIPPING UWE
IPC: D05B35/10
Filed: 1991-03-08
Abstract: Cloth feed guide for a sewing machine attains parallel edges using free running wheels. By means of a pneumatic driven cam, the guide wheel directs the cloth to the needle. Multi-layer seaming is controlled by a system of both over and under positioned guide rollers. The guide system control incorporates light sensors. The small wheel (3) pref. has an axle held on a spring mounted side bar. This may have a pneumatic cylinder attached, so that the wheel can be pressed down onto the cloth, or released completely. For control of the material, there may be four wheels, mounted in a manner to permit the cloth to advance towards the needle, with constant adjustment. This is made by having an air pressure control arrangement (15), which contains the valves and pipe connections to activate the pneumatic cylinders (4), over the rollers. Air pressure moves the cam (2) which is held centrally on the spring device (12). In turn, the cam moves a steering pin attached to it, which enters an arm on the wheel bracket. ADVANTAGE - The system avoids the use of a drive on the wheels. The guide system is manoeuverable, and so can follow a shaped edge on the cloth.

Title: Filtering aq. suspensions in filter column - with closed backflushing circuit fed with filtered liq., used for treating contaminated aq. solns., coolants and lubricants from metal machining, etc.
Inventor: KNOLL JUERGEN DIPL ING
IPC: B01D24/12
Filed: 1991-12-21
Abstract: Treatment of aq. media, contaminated with fine particles and sludges from machining or cleaning processes, involves passing the liq. from a dirty water tank through a labyrinthine filter column (filled with quartz sand, glass beads or the like) to a clean liq. tank. the column is periodically cleaned by back-flushing. Liq. is withdrawn from the clean liq. tank for back-flushing the column in a closed circuit. The contaminated back-flushing liq. is passed from the column to an additional bag filter. The cleaned back-flushing liq. is returned to the clean liq. tank. The contaminants, remaining in the filter bag are disposed of separately. A filter unit for carrying out the process is also claimed. USE/ADVANTAGE - The process is useful for treating contaminated aq. solns., coolant/lubricants, etc. from metal machining and cleaning processes. It provides optimal cleaning of the aq. media, recovers the back-flushing liq. as clean liq. and produces waste only in the form of dry particles which can be easily disposed of or opt. reused.
