Title: Power supply train for underground mining
IPC: B61B3/00
Filed: 1981-03-24
Abstract: The invention relates to a power supply train for underground mining. On a suspension rail, supporting frames which can be moved with the aid of supporting trolleys are suspended. Previously, double-axle supporting trolleys were used in a structure which, due to the suspension of the supporting frames, gave rise to a relatively large constructional height. This can be reduced according to the invention in that the transverse strut of the supporting frame penetrates the housing of the supporting trolley and is guided in a non-tilting fashion within the housing, in that the transverse strut rests so as to be capable of being displaced in the direction of rotation on supporting elements which are rigidly connected to the housing, and in that the transverse strut has stops which engage on the housing and by means of which the said strut is secured against displacement in its longitudinal direction. Not only does this structure give rise to a lower overall constructional height, it even makes a single-axle design of the supporting trolley possible. <IMAGE>

Title: Automated material store with shelf-loading appliance
Inventor: DEY GUENTER
IPC: B66C1/02
Filed: 1981-03-26
Abstract: Automated material stores with shelf-loading appliances generally comprise telescopically extendable gripping elements. The gripping devices designed for picking up the material stored are held on correspondingly telescopically movable intermediate arms. This design requires a considerable amount of space, in particular in a horizontal extension plane. This is to be remedied by the shelf-loading appliance being formed from two columns which are arranged one behind the other at a distance apart in the direction of movement and are guided at their respective end areas and between which the actual feeding device can be moved. The feeding device is held in shields movable up and down in the vertical direction and is supported and guided therein in such a way that a maximum of 1/3rd of the supporting-arm length serves as supporting plane and these movable rails directly accommodate the actual gripper device.

Title: Magazine for push-in electrical assemblies
Inventor: NIGGL HEINZ
IPC: H05K7/14
Filed: 1981-03-30
Abstract: The guide rails for the assemblies are held in recesses (5) (which are in the form of holes) in horizontal U-shaped supports (1). The recesses (5) are distributed uniformly over the support (1) and are arranged aligned in pairs in its side limbs. At its front end, the support (1) is cut off approximately in the centre of a pair of recesses so that projections (6) are produced by means of which it is inserted into corresponding perforations (7) in a side plate (2) of the magazine. A plug-in nut (4) is inserted into the adjacent pair of recesses, is clamped to the side plate (2) by means of an attachment screw (3) and in consequence pulls the support (1) against the side plate (2). In consequence, only simple separation of the support (1) (which is delivered as a pre-perforated rod material) is required for constructing the projections (6) and for insertion of the plug-in nut (4). <IMAGE>

Title: Method and device for controlling ignition energy
Inventor: OSHIAGE KATSUNORI
IPC: F02P3/045
Filed: 1981-04-10
Abstract: A method and a device for controlling ignition energy cause high ignition energy to be fed to the spark plugs only when the internal combustion engine is operating in an instable operating state. The instable operating state of the internal combustion engine is determined by detecting the difference of the maximum speed of revolution of the internal combustion engine within a specific crank shaft rotary angle or by detecting the low-frequency oscillation which is produced by the internal combustion engine. The ignition energy is controlled by calculating a suitable pulse width of an ignition signal or by changing a high voltage which produces plasma within the cylinder. The device according to the invention for controlling ignition energy has a crank shaft angle sensor (1) or a sensor (5) for low-frequency oscillations, a computing and storage device (3) and an ignition system (4) which, if necessary, comprises a power source (42) for producing plasma. <IMAGE>

Further details relate to the connection of the structural unit to the supporting construction, the mode of construction and connection of the built-over aggregate silo, the position, arrangement and design of the operating parts in the structural unit and the use of the structural unit in conjunction with a serial metering apparatus flush with the ground, the space of the aggregate balance being taken up by an intermediate recipient without a balance.
Patent DE-3118272-A1 (DE)
Title: Continuous extractor
Inventor: PLUTA WERNER DR
IPC: B01D11/02
Filed: 1981-05-08
Abstract: The invention relates to a continuous counter-current extractor which can have universal application, even for raw materials which are difficult to extract, such as mucilaginous raw materials, the extraction medium flowing from bottom to top through a relatively long raw material layer situated in the screw flight and the raw material being moved in counter-current from top to bottom. As a result, a high concentration gradient is achieved and the possibility of flooding is excluded as far as possible. The extractor essentially consists of a cylindrical vessel having an extractor screw driven at one end and lying tightly against the vessel wall. The raw material is transported from a storage container with the aid of a smaller screw into the upper screw flight of the extractor screw. The feed screw is arranged on the extractor screw so that raw material swelling occurs in this as a result of wetting by the extract solution passing out. The extraction medium is introduced into the extractor by a pump at the conical discharge part. The discharge of the extracted raw material is carried out by a discharge screw in which the adhering extraction medium or the extract solution is squeezed off.

Patent DE-3151960-A1 (DE)
Title: Heating installation
Inventor: EDER FRANZ X PROF DR ING
IPC: F25B9/14
Filed: 1981-12-30
Abstract: With the patent application, protection is sought for a heating installation which consists of a thermally operated heat pump and a reheater, in which the proportion not used on the introduction of the heating capacity for the heat pump is transferred directly to the useful heating circuit. According to the invention, the heat pump is made as a regenerative circular process, operated with high-pressure helium as the working medium, which in each case comprises a displacement piston, a heat exchanger and thermal regenerator. In the low-temperature cylinder, the thermal capacity supplied at low temperature is "pumped up" to the useful temperature, while the high-temperature cylinder, the displacement piston of which is moved by an auxiliary drive periodically and phase-shifted by 90 DEG  in relation to that in the low-temperature part, is supplied with the drive capacity in the form of heat by means of oil or gas burners. The high-temperature part of the heat pump, in which the same pressure prevails at the same time in each part volume, works as a thermal compressor and generates periodic pressure changes which are made useful in the low-temperature cylinder as a heat pump process. Connected downstream of the heat exchangers for useful heat production is the reheater which utilises both the burner capacity not transferred to the high-temperature part but also, with the aid of an additional burner, produces a substantially large proportion of the overall heating capacity. The patent rights applied for relate in detail also to the design of the heat exchanger for burners, of the regenerators and a device for regulating the heating capacity with constant operating speed and constant average filling pressure.

Title: Apparatus for conveying ferromagnetic workpieces
Inventor: METZ R ING GRAD
IPC: B65G54/02
Filed: 1982-04-02
Abstract: The conveying apparatus, which has holding magnets along a conveying path, which magnets are provided with rollers to keep the workpieces to be conveyed at a distance from the poles of the magnets, can be used as lifting or holding magnets when their coils are subjected to direct or single-phase alternating current and act as the primary section of a multi-phase linear induction motor when the coils, which are arranged one behind the other, are fed by the phases of a source of multi-phase alternating current. Sensor devices which take the form of induction coils or semiconductor chips are provided between the poles of the magnets or around the poles to determine the exact position of a workpiece along the conveying section or the position of a workpiece in relation to one of the holding magnets. The alterations in the physical properties of the sensor devices caused by entry of the ferromagnetic workpieces into the magnetic field act as signals for the purposes of control, in order to deposit the workpiece at a specific point on the conveying section, for example. Such signals can also be used for switching exciting coils on or off or for pole reversal in the latter.

Title: Brake disc designed as a rotating heat exchanger tube
Inventor: BAEHRLE FRIEDRICH
IPC: F16D65/853
Filed: 1982-06-23
Abstract: The invention relates to a brake disc which can be cooled in accordance with the principle of the heat exchanger tube, which contains a system of heat exchanger tubes integrated into the brake disc and which is designed as a compound structure comprising sheet-metal components and grey cast iron. Since grey cast iron is not sufficiently vacuum-resistant, the system of heat exchanger tubes is surrounded completely and on all sides only by sheet-metal or steel components. Secured in thermally conducting fashion on the sheet-metal components in the region of the braking surfaces are two friction rings of grey cast iron situated axially opposite one another, it being possible to accomplish this by brazing in order to allow renewal to be carried out. In addition, at least one friction ring should overlap at the inside in order to permit balancing. Brake discs of this kind are suitable in particular for highly loaded or aerodynamically enclosed vehicle brakes.
