Patent DE-3332764-A1 (DE)
Title: Device for elevating dust-like material, especially cement raw meal
IPC: B65G53/22
Filed: 1983-09-10
Abstract: The device, which can also be called an elevator, has a conveying tube 8, through which a mixture of air and dust-like conveyed material is conveyed vertically upwards. This tube terminates in a stabilising receptacle 11, in which the conveyed material and the air are separated. A diffuser 10 is arranged between the conveying tube 8 and the stabilising receptacle 11 to reduce the speed of the flowing agent and in so doing to permit the separation of conveyed material and air without significant loss of pressure and without a correspondingly high degree of wear in this region. The use of expensive and rapidly worn mechanical braking aids is no longer required. <IMAGE>

Patent DE-3338050-A1 (DE)
Inventor: ZIESE ROLF ING GRAD
IPC: G01S15/89
Filed: 1983-10-20
Abstract: A method for the acoustic surveying of the surface contours of the bottom of a body of water by means of a crossed fan beam echo sounding arrangement wherein, for the purpose of obtaining an accurate, unfalsified surface contour, the measured contours obtained by scanning the bottom of the body of water in a direction transverse to direction of the heading of the surveying ship are recalculated by means of a continuously checked and adapted correction value. The correction value is determined from deviations between a calibration contour and a test contour. The calibration contour is a longitudinal contour which is formed from measured contours lined up in the direction of the ship's heading and cover a strip on the bottom of the body of water extending perpendicularly below the path traversed by the surveying ship. The test contour is recorded in the same manner as the measured contour but with the echo sounder pivoted by 90 DEG  about the elevation axis of the ship, i.e. from the same strip of ground perpendicularly below the fore-to-aft axis of the ship with which the calibration contour is associated.
Patent DE-3340440-A1 (DE)
Title: Process for producing coarse-ceramic mouldings
IPC: C04B33/32
Filed: 1983-11-09
Abstract: A process for producing coarse-ceramic mouldings, for example bricks, is described. The starting material is a suitable granulated product, for example expandable clay or expandable shale, which is selected with respect to its grain size distribution in such a way that open channel-like voids, which allow free passage of gas and whose volume is preferably more than 15% of the total volume of the loose material, remain in between the granulated product. Such a quantity of a binder slip, for example clay in water, is added to this granulated material that the latter is enveloped as completely as possible, but that the channels remain open. After moulding, a part of the free water is removed absorptively or chemically from the granulated product/slip mixture until sufficient stiffening is obtained. The material is then dried and fired. The preferably used grain size spectrum of the granulated product is 3-8 mm. For absorptive binding of a part of the free water, a porous material which absorbs water slowly, for example expanded clay, can be used as the granulated product. For chemical binding of the water, gypsum can be added to the mixture.

Patent DE-3413437-A1 (DE)
Title: Screw vane diaphragm pump with eccentric automatic control of lamella vanes
Inventor: KOWALZIK HARTMUT
IPC: F04B43/02
Filed: 1984-04-10
Abstract: Since conventionally constructed diaphragm pumps, whether driven mechanically or hydraulically, are suitable only for pumping pure liquids, as they are equipped with valves for controlling the suction and discharge stream, the screw vane diaphragm pump has been conceived for pumping contaminated liquids, sludges and pastes having a high viscosity. In the essential part of the invention, the lamella vanes with eccentric automatic control, control valves become superfluous, because said lamella vanes effect the displacement of the flow medium, provide complete support of the elastomeric diaphragm and effect shut off and control of the delivery stream. The control of the lamella vanes themselves is carried out automatically by a roller-bearing worm shaft, whose design corresponds to that of a multiple crankshaft. Using said roller-bearing worm shaft reduces the friction within the drive to a minimum and thus requires only a relatively low drive input.

Filed: 1984-05-07
Abstract: The invention relates to a capacitive pulsing device for electric stepping motors which are used for driving and positioning in printing devices of data-processing systems. The aim of the invention is to specify a capacitive pulsing device which avoids the disadvantages of the prior art. The technical object is to create a capacitive pulsing device which has a higher transmission factor with small dimensions, with two high-frequency voltages which are in antiphase and have the same amplitude, with two fixedly arranged incoming-supply plates, with an output-coupling plate which is arranged fixedly with respect thereto, and with movable coupling elements. The invention is characterised in that the two input-supply plates have a centre separation in the movement direction of the coupling elements which is equal to half the periodicity of the arrangement of the coupling elements, in that the output-coupling plate is split into two electrically connected sub-plates which are of the same size, are allocated with the same geometrically effective areas to the input-supply plates, and are located on the same plane with the same co-ordinates in the movement direction of the coupling elements, and in that the coupling elements are electrically conductive plates, which are arranged in an insulated manner, on three-dimensional projections of the element which can rotate. <IMAGE>
Patent DE-3418067-A1 (DE)
Title: Centre drill
Inventor: STUTTER GERHARD
IPC: B28B1/48
Filed: 1984-05-16
Abstract: The centre drill is an adjunct to the electrically operated potter's wheel. It is possible with its aid to "open" centred lumps of clay, i.e. to drill a wide hole through their exact centre. This makes it possible to turn the said lumps of clay to make pots. This is intended primarily to permit badly disabled people, especially those whose hand movements are limited and those lacking in experience, to achieve a success rate of 100% at the potter's wheel without great effort. Procedure: The centre drill with its two supporting plates (4) is placed on the edge of the potter's wheel (1). The push-button (5) is pressed gently downwards by hand. A metal ring (6) is attached to the bottom of the drill spindle, which metal ring (6) cuts a wide, precisely centred hole into the rotating lump (3) of clay. A bent stay bolt (7) stops the drill from drilling too far into the lump of clay.

Title: Phase-controlled circuit arrangement
Inventor: MASAKI KAZUMI
IPC: H02M5/257
Filed: 1984-05-21
Abstract: The invention relates to a phase-regulated zero-crossover AC circuit. The circuit arrangement contains a regulating circuit having a time constant, an AC bridge (which is connected to the regulating circuit and to an amplifier and contains a variable resistor in one bridge arm), an amplifier for an unbalanced voltage which is produced in the bridge, switching means for the DC supply of the regulating circuit and of the amplifier, and a thyristor which is controlled via the amplifier. The circuit is constructed in such a manner that the thyristor is always non-conductive or not carrying current when the AC voltage is connected and in such a manner that current flows through the thyristor from a zero-crossover of an oscillation of the alternating current starting from a current which rises successively to a predetermined value within a time period which is determined by the time constant of the regulating circuit.

Title: Automatic gambling machine with a symbol gambling device and winnings display ladder for wins which differ in steps
Inventor: GAUSELMANN PAUL
IPC: G07F17/32
Filed: 1984-07-18
Abstract: For an automatic gambling machine comprising a symbol gambling device (1) controlled by a random-number generator (4) and a control device (3), which displays a symbol combination deciding on winning or losing before the end of the game, with a processor (5) which determines a winning signal representing the magnitude of the win differentiated into steps from the random number, by means of which signal the control device (3) activates one of a number of winnings-oriented display elements (for example 8), the latter being combined to form a winnings display ladder (9) in strictly monotonic winnings sequence, it is proposed that the processor (5) transforms equally-distributed random numbers into random numbers of predetermined distribution in order to decide on an increase of the gained winnings to the next-higher winnings step in accordance with the predetermined distribution. The automatic gambling machine according to the invention enables the gained winnings to be increased, as a result of which, on the one hand, the gambler does not suffer any losses and, on the other hand, the associated increase in payout remains within a calculable and economically supportable frame. <IMAGE>

Title: Apparatus for temperature-controlling integrated electronic components
Inventor: DAHINTEN HEINZ
IPC: G01R31/28
Filed: 1984-11-09
Abstract: To temperature-control (heat or cool) integated electronic components, for example in testing machines for said components, an appreciable expenditure on constructional space and on control devices was hitherto necessary. It is therefore proposed to carry out the temperature control of the components (1) by bars (2) through which temperature-controlled air (3) flows. Heat is transferred to the components by thermal conduction, thereby achieving a short heating-up and cooling-down time. Good constancy of the temperature along the bars is effected by the air flowing through them. <IMAGE>
