Title: Dam building mixt. esp. for lining underground mine tunnels - contains waste gypsum, red mud, and waste calcium chloride obtd. from gas washers
Inventor: HOELTER HEINZ ING GRAD
IPC: E21F15/00
Filed: 1980-08-20
Abstract: This is an addn. to 3026454, which described a dam material contg. unbaked CaSO4 waste obtd. in removing sulphur from combustion gases, and red mud waste obtd. from the Al industry. The novelty in the present invention is that the material contains the unbaked CaSO4 waste; red mud and/or waste iron dusts from the smelting industry; and/or waste CaCl2 obtd. from waste gas washers in coal-burning power stations or garbage incinerators. The above mixt. pref. also contains bentonite to increase its strength; and/or dust obtd. in mfg. Si or Fe-Si to increase its density and fire-resistance. Prior to its use, CaO, Ca(OH)2 and/or Na2CO3 are pref. added to the mixt. to reduce its setting time and improve its hardening properties. The waste CaCl2 obtd. from gas washers can only be destroyed by processes using a large amt. of energy. The invention not only solves the problem of disposing of the CaCl2, but prevents the freezing of the dam building mixt. so it is easy to store and to transport.

Patent DE-3042015-A1 (DE)
Title: Electrohydraulic servo-valve unit with hydraulic control - has control slider whose control and measuring stroke is converted into force by mechanical, series, regulating members
Inventor: KUCHARZYK REINHARD ING GRAD
IPC: F15B13/044
Filed: 1980-11-07
Abstract: The control element of the servo-valve unit is formed by insensitive proportional valves. The servo-valve unit is intended for load-dependent control of pressure medium motors. The control stroke and/or the pressure medium flow is proportional matched to an electric signal current. The control or measuring stroke of a control slider or a controllable seat valve (19) acts over mechanical, series-connected control elements (17,10), converting the measuring stroke into force on a control slider (3) coupled to a valve seat (9). The force affects at the opposite long end a magnetic plunger (2) of the control magnet (1). Thus a given stroke of the control slider or controllable valve is included in a given force of the magnetic plunger, independent of any pressure medium forces. An axial force effect of the pressure medium is removed from the measuring pin in a spring chamber.

Title: Device for producing a 90 DEG  phase shift
Inventor: SANTOS JOAQUIM DIPL ING
IPC: H01P1/18
Filed: 1981-02-06
Abstract: A 3 dB hybrid having four connections (9, 10, 11, 12) is used to produce a phase shift of 90 DEG  between two radio-frequency signals which follow one another in time. The radio-frequency signal whose phase is intended to be shifted is supplied to the 3 dB hybrid via a switching device (1), the three signal inputs (2, 3, 4), two signal outputs (5, 6) (these are connected to two input connections of the 3 dB hybrid) and a control input (7). The signal inputs (2, 4) to which the RF signal is not supplied are in each case connected to a terminating impedance (14, 15). The switching device in each case connects the RF input (3) and one terminating impedance to the input connections (9, 10) of the 3 dB hybrid, to be precise such that the RF input is connected to one input connection or the other of the 3 dB hybrid, and the other input connection of the 3 dB hybrid is in each case connected to one of the two terminating impedances, depending on the switch position. The RF output signal whose phase is shifted is always picked off from the same output connection of the 3 dB hybrid; the other output connection (12) is connected to a resistor (13). <IMAGE>

Title: Scratch-resistant, antistatic sound and picture recording media, and method for producing them
Inventor: BREUNINGER AXEL
IPC: G11B3/68
Filed: 1981-02-21
Abstract: Scratch-resistant and antistatic sound and picture recording media made of plastics are obtained by providing their surfaces with a thin metal film. The gold films hitherto applied by electroplating or in high vacuum had the drawback that they were either not sufficiently abrasion-resistant or strongly impaired the sound reproduction quality. Better results are achieved if the surfaces of the sound or picture recording medium (1) are coated with a thin iron-chromium alloy coating (2) applied in high vacuum and a thin noble-metal coating (3) applied in high vacuum. <IMAGE>

Title: Device for joining together two single adhesive tapes provided with an adhesive layer on one side to form a double adhesive tape
Inventor: RAMMELMEYR PAUL
IPC: B65H39/16
Filed: 1981-03-25
Abstract: A device for joining together two single adhesive tapes (42 and 52) provided with an adhesive layer (60) on one side serves to produce a double adhesive tape (68) which is provided with an adhesively bonded-together overlapping region (72) on both sides, in each case partly adhesive, such that surfaces to be worked on, in particular during painting work, sharp edges can be protected by the adhesion on one side and the entire surface can be protected with cover sheets by adhesion to the other surface. For this purpose, two single adhesive tapes (42 and 52) are transported in planes (76 and 82) offset with respect to one another with the adhesive surfaces (60 and 62) towards one another, so that an overlapping region (72) free of transverse forces can be formed, it being possible to make the adhesive bond more intensive and thereby more durable, stressable with higher forces and wrinkle-free by corresponding deflection (66) of the two tapes (42 and 52) over a common deflection roller (48), so that no paint residues can press through the wrinkles onto the surface to be covered. <IMAGE>
Patent DE-3113737-A1 (DE)
Title: Feed pump
Inventor: SCHULZ ECKHARD
IPC: F04B11/00
Filed: 1981-04-04
Abstract: The feed pump (delivery pump) comprises  a drive shaft, a number of cylinder cavities assigned thereto, which are distributed in a regular manner on a circle concentric with the axis of the drive shaft, a number of delivery pistons each individually assigned to the cylinder cavities,  an inlet and outlet control appliance for the flow medium, and a conversion gearing for converting the rotating driving motion of the drive shaft into a translatory driving motion of the delivery pistons. Provided as the conversion gearing there is a cam which corotates with the drive shaft and is continuously scanned by the piston rods of the delivery pistons by means of one feeler roll each. In order to provide a high-speed appliance which operates without cavitation and vibration and produces little noise, the cam has the shape of a simple or higher-order sinusoid, and the cylinder cavities each have a discharge cavity with a cross-sectional dimension which is greater than the cross-sectional dimension of the delivery pistons which, as plungers, enter their pumping chambers during the delivery stroke by one side and in a delimited manner.
Patent DE-3117674-A1 (DE)
Title: Overhead conveyor arrangement for the transport of bulk material and excavated (loose) material (raw ore)
Inventor: KLEINSCHMIDT DIETRICH
IPC: B66C3/02
Filed: 1981-05-05
Abstract: The invention relates to an overhead conveyor for the transport of bulk material and excavated material, with rails along which transport cars can be moved in a suspended manner between loading and unloading stations. The transfer cars are provided for receiving excavated material in bulk, and in fact in various configuration. One basic configuration starts from half shells which can be moved apart horizontally and lowered down to the bottom of the work space. They move there from both sides towards bulk material or raw ore, enclose it between them, lift it up to the travelling mechanism of the transfer car and move it away to the disposal station. In another configuration, the half shells move apart and together at the top at the travelling mechanism. An electromagnet lifts the ferriferous raw ore to the level of the half shells, which then enclose it by moving together. In a further embodiment, a box is arranged at the running mechanism. The base of the box consists of flaps which can be swung away. An electromagnet lifts the ferriferous raw ore into the box, whereupon the flaps close. In still another embodiment, the travelling mechanism is of two-piece design. One travelling mechanism carries the electromagnet and the other travelling mechanism carries a tub-shaped receptacle. The electromagnet lifts the ferriferous raw ore and the tub-shaped retaining receptacle travels under the raised raw ore, which then drops into the tub-shaped retaining receptacle. A further embodiment is provided with a bucket-like retaining receptacle, which, sweeping over the ground, picks up the bulk material or raw ore. The bucket-like retaining receptacle can pick up a multiple receiving volume of a bulk-material pile or raw ore.
Patent DE-3123248-A1 (DE)
Title: Tight coke oven door II
Inventor: STOG WILHELM ING GRAD
IPC: C10B/
Filed: 1981-06-11
Abstract: Under the most stringent environmental protection regulations, the tightness of coke oven doors is of particular importance. The coke oven doors seal the coke oven by sealing edges which extend around the door body and are tightly pressed together with the door body onto the oven frame. The sealing edges are part of a sealing plate and are loaded by a corrugated spring which likewise extends around. The cages containing the corrugated spring are each joined via flat irons to a T-girder extending in the longitudinal axis of the door body and are supported, at least in the area of the locking device, by transverse girders extending through the latter. On the inside of the door body, a coking plate held by spacers is arranged in such a way that the complete coke oven door is characterised by a very low dead weight. Sealing of the coke oven is guaranteed by the light-weight construction, by the coke oven door which is to be introduced to fit exactly and by the uniform and high loading of the sealing plate with sealing edge. Good readjustability is provided by the mobility of the sealing plate and by a readjustable corrugated spring. <IMAGE>

Title: "Hydrostatic axial-piston machine"
Inventor: MEYERLE MICHAEL ING GRAD
IPC: F04B1/20
Filed: 1981-06-26
Abstract: The invention relates to a hydrostatic axial-piston machine, whose pivoting body (1) for supporting the swash plate (29) is constructed to be particularly stiff with respect to vibration. To this end, the side wall (31) of the pivoting body (1) was raised up in the shape of a drum. While it embraces the cylinder body (28) its special shape permits an adequate pivoting motion of the pivoting body (1). A servo-piston (6) is arranged transversely to the driveshaft (22) and to a corresponding driven shaft, and a pivoted lever (4) is passed closely alongside the cylinder body (28) and hung into (secured in) the servo-piston (6). This results in a compact, space-saving arrangement which fits in a high-pressure casing. The unit emits little noise and can be manufactured cost-effectively. <IMAGE>
Patent DE-3127943-A1 (DE)
Title: Device for monitoring the distance between two persons or objects moving relatively to one another
Inventor: AEPLER REINHARDT DR
IPC: G01S13/82
Filed: 1981-07-15
Abstract: In this device, two transmitter/receiver units and at least one alarm transmitter are provided. The transmitter/receiver units are constructed for monitoring each other, by means of mutual control for signal exchange, in such a manner that in each transmitter/receiver unit, a signal received from the transmitter of the other unit is used for controlling the own transmitter for the transmission of a signal, if necessary after an adjustable or set delay time. The signal received from the transmitter of the other unit is also used for deleting a precontrol for the alarm transmitter or to prevent the alarm transmission in another manner. If the distance between the persons or objects to be monitored becomes greater than the range of the transmitter of one of these units, the mutual transmitting connection is broken. Thus, the control for suppressing the alarm transmission also disappears, in other words, the alarm transmitter is released for transmitting an alarm. By constructing the transmitter/receiver units from microcomponents, the transmitter/receiver units can be easily attached, for example to items of clothing or jewellery such as wristwatch straps, watch cases and the like. The monitoring device can be used virtually universally, for example for persons, especially small children, for animals, for objects of value and the like.

The pulse starts up a signal device, for example a flashing light, which emits an optical signal into the surroundings and warns motor vehicle drivers of the risk of black ice.
Patent DE-3149332-A1 (DE)
Title: Ignition system for an internal-combustion engine
Inventor: KOPPER WERNER DIPL ING
IPC: F02P3/04
Filed: 1981-12-12
Abstract: An ignition system is proposed, which is used for igniting the compressed fuel-air mixture in a cylinder of an internal-combustion engine. In this ignition system, the primary winding (5) of an ignition coil (6) is connected in series with an electronic interruptor (7). Current is passed via the primary winding (5) as soon as a threshold switch (15) is in a switched-on state. The threshold switch (15) can be controlled by an upstream AC generator (27). From the AC voltage signal (Uc) of the AC generator (27), the curve section (Ue) preceding the peak value (Ud) is used to switch on the threshold switch (15), and the curve section (Uf) following the peak value (Ud) is used to switch off the threshold switch (15). The switching-on value (Ua) and the switching-off value (Ub) are preset to the same polarity with respect to the zero value (0) of the AC voltage signal (Uc), to be precise with the object that, when the ignition system is switched on but the internal-combustion engine is not in use, the interruptor (7) cannot pass current via the primary winding (5). According to the invention, a circuit path (31) is provided having a voltage-dependent switching element (32) by means of which, below a minimum voltage, the bias voltage on the threshold switch (15) can be varied in the sense that at least the switching-off value (Ub) of the threshold switch (15) changes in comparison with the presetting of its polarity with respect to the zero value (0) of the AC voltage signal (Uc) in order to ensure that, when the internal-combustion engine is taken into use, the ignition time corresponds at least virtually in time with the top dead centre position of the piston. <IMAGE>
