Title: Liq. distribution inside ion exchange column - through flat transverse internal chambers with laminates sprays
Inventor: ARION NICOLAI MICHAEL DIPL ING
IPC: B01J47/022
Filed: 1980-12-11
Abstract: Operating and regenerating an ion exchange column with spray bases involves feeding liq. to the resin bed in the main chamber of the column and removing it from the bed through separate chambers of relatively small vol. w.r.t. the head and base chambers. Each spray base is a flat chamber between parallel walls transverse to the column, with inlet and outlet feeder pipes respectively. From the head chamber the regenerating liq. is distributed as flat sprays through laminar slots into the resin body, and at the base is collected through similar slots into the base chamber and the outlet pipe. The process is reversed for the liq. being purified. No dilution of the regenerating medium and regeneration prod. soln. or of the exchange resin in the head and base parts of the column, and washing water consumption reduced.

Title: Arrangement for early fire detection on a belt conveyor
Inventor: ORMANNS SIEGFRIED
IPC: B65G43/02
Filed: 1981-02-21
Abstract: A description is given of an arrangement for early fire detection on a belt conveyor whose cord conveyor belt is supported on idlers which are mounted approximately axially next to one another and at a distance behind one another in the conveying direction. In order to detect an impermissibly intense heating of the idlers on a belt conveyor in good time and to obviate the danger thereby caused of a mine fire, it is proposed that the cord conveyor belt (10) is provided on the side (12) facing the idlers (11) with a temperature measuring substance which changes colour when heated, that the temperature measuring substance is arranged in punctiform, spotty or striped zones (13) distributed over the belt width in such a way that during one belt revolution each idler (11) comes into contact with at least one temperature measuring zone (13), and that the scanning head (20) of a colour monitoring unit (21), which responds to colour changes in the temperature measuring substance, is aligned with respect to the tracks of the temperature measuring zones in such a way that all the temperature measuring zones are scanned at a point of the belt conveyor (1) during a revolution of the cord conveyor belt (10). An idler which comes into contact with a temperature measuring zone of the cord conveyor belt (10) as it revolves and is excessively heated leads to a colour change in the associated heat measuring substance, and this colour change is detected by the scanning head (20) at at least one point of the belt conveyor. In order to prevent premature wear of the heat measuring zones (13) during normal revolution of the cord conveyor belt (10), the heat measuring substance or its carrier material should have a greater hardness than the surrounding material of the cord conveyor belt. It is possible, if appropriate, to fix a brush strip or bond strip in front of the scanning head, which cleans the colour measuring zones before these run into the scanning gap (23) below the scanning head (20). <IMAGE>

Patent DE-3133617-A1 (DE)
Title: Method for producing ice figures
Inventor: HOBELSBERGER JUN JOSEF
IPC: F25C1/04
Filed: 1981-08-25
Abstract: A method for producing ice figures for decorative purposes is shown, in which water is poured into a casting mould (1) which depicts the ice figure as a negative shape and has substantially rigid walls (12a, 41), the filled casting mould (1) is cooled to below the freezing point of the water and the ice figure then produced is removed from the casting mould (1). Previously, ice figures were not cast, but hewn out of blocks of ice using a hammer and chisel. Previously a production method by casting appeared to be impossible due to the knowledge of the great expansion in volume of the ice relative to the quantity of the freezing water and due to the requirement for a precise, finely structured and greatly diverse shape of an ice figure, which can only be achieved by a rigid mould. It has surprisingly been shown that ice has such a high flow capacity that even relatively complicated casting moulds (1) with sturdy walls are filled with ice without suffering damage insofar as the ice is only given a yielding possibility for expansion inside or outside the casting mould (1). Furthermore, a casting mould (1) which is suitable for carrying out the method is shown, which casting mould consists of a case (2, 27) into which shaped pieces (5 to 8; 31 to 36) are introduced, which enclose a hollow space (12, 40) which depicts the negative shape of the desired ice figure. Various shaped pieces (5 to 8; 31 to 36) are to be designed and adapted to one another in such a way that many shapes of ice figures can be created by combining a limited number of shaped pieces. <IMAGE>

Title: Magnetic coupling
Inventor: TAIANI PATRICK M
IPC: F16J15/50
Filed: 1981-09-11
Abstract: A magnetic coupling (clutch) has a housing with two end discs, an annular input drive part which is fitted on the inside with a number of magnets, and an input drive part which is arranged inside the same and is fitted with a number of magnets. The input drive part and the output drive part are supported on the end discs such that they can rotate, so that the output drive part is caused to rotate by magnetic interaction in the event of a rotation of the input drive part. A separating wall which separates the input drive part from the output drive part and extends between the end discs forms a hermetic seal for the output drive part. The separating wall is composed of a multiplicity of annular laminates which are located close to one another in the axial direction, consist of a non-magnetic material and are held between the end discs, subject to axial compression. In one embodiment, the laminates have a grooved profile in radial section so that mutually adjacent laminates engage in one another. In another embodiment, the laminates have a rectangular shape in radial section and are additionally supported by a thin-walled bush which extends between the end discs and consists of non-magnetic material. The separating wall, which is composed of laminates, reduces power losses and heating resulting from eddy currents caused by the magnetic flux and, in this case, at the same time has a strength with respect to shear forces and thrust forces which is sufficient for use on a pressure container (pressure vessel).

Title: Automatic manipulating, transporting or welding machine
Inventor: BILSING ALFRED DIPL ING
IPC: B23K11/31
Filed: 1981-09-15
Abstract: The invention relates to an automatic manipulating, transporting or welding machine with a tool carried by a movable arm and rotatable at its end about several axes. In order to simplify the drive of the outermost axis and improve the accuracy of the control of this axis, it is proposed to lead the pressure fluid used to drive the outermost axis up to the axis located in front of the outermost axis and only then transmit the drive force via mechanical machine elements to the outermost axis. A displacement measuring system allocated to the outermost axis and a control valve influenced by this displacement measuring system are also preferably attached to the shaft located in front of the outermost axis. The control valve controls a hydraulic cylinder forming the end of the hydraulic system. To further relieve the load on the drive of the outermost axis, it is proposed in the case of an automatic welding machine to also mount the welding transformer on the spindle carrying the outermost axis. <IMAGE>

Title: Circuit arrangement for controlling the conducting phase of the switching transistor in switched-mode power supplies
Inventor: SECKENDORF WILFRID
IPC: H02M1/08
Filed: 1981-11-09
Abstract: The invention relates to a circuit for controlling the conducting phase of switching transistors in switched-mode power supplies, and refers to the field of supplying power to electronic apparatuses. The aim and object are to develop a circuit which allows base-current control of the switching transistor proportional to the collector current at a small additional cost, and which considerably reduces the negative influence of the storage time of the switching transistor on the control characteristics of the switched-mode power supply. This is achieved according to the invention in that a transistor is used as the control transistor which has a complementary conductivity to the switching transistor, with its collector connected to the foot of the control winding in the base circuit of the switching transistor, with its emitter connected via a resistor to the emitter of the switching transistor, with its base connected to the connection of the emitter resistor of the switching transistor remote from the emitter of the switching transistor, and a further resistor being arranged between the collector and base of the control transistor. In a development, a diode is arranged between the base of the control transistor and the connection of the emitter resistor of the switching transistor remote from the emitter, and is shunted-out by a capacitor.

Title: Screw- and nut-loosening tool
Inventor: MANN ERWIN
IPC: B25B13/48
Filed: 1982-02-01
Abstract: The invention relates to a spider wrench having opposite sockets, the supporting elements consisting of hollow bodies. The advantage consists in the fact that smaller hollow-body dimensions can be integrated in the spider wrench. At the crossing point, the hollow profiles are crossed in such a way that the telescope-like extensions can be pushed through from all sides. As a result, all of the sockets situated on the spider wrench can be used interchangeably. To tighten or loosen tight-fitting screws and nuts, the telescope-like extension can be pulled out from the spider wrench, as a result of which the lever arm is enlarged many times. To speed up this operation, a ratchet can be fitted in each case at the tube end. Polygonal hollow profiles have proved successful for increasing the stability. The integrated tubes can be firmly held at the end by a ball spring catch, and can be pulled out by a small handle. To save space in motor vehicles, the same system can also be designed without tube crossing.
