Title: Magnetic head with main pole and auxiliary pole and process for production thereof
Inventor: SCHEWE HERBERT DR
IPC: G11B5/23
Filed: 1986-12-03
Abstract: The magnetic head of laminated construction for a recording medium to be magnetised perpendicularly (vertically) contains on a non-magnetic substrate a magnetic conducting element which guides the magnetic flux and has two magnet legs, the end pieces of which form a thin main pole and a comparatively thicker auxiliary pole. In this case, the two magnetic poles are separated by an isolating gap layer of at least 5  mu m in extent. The intention is for this magnetic head and, in particular, its gap layer to be relatively simple to produce. For this purpose, it is envisaged according to the invention that the substrate (3) is provided with a recess (20), in which the end piece (12) of the one magnet leg (10), forming the auxiliary pole (P2) and a portion (10a) of this leg adjoining the latter as well as a part (18a) of the gap layer (18) are arranged in a sunken manner. <IMAGE>

Title: Grippers for laying masonry blocks in rows
Inventor: FRIEMELT CHRISTIAN
IPC: E04G21/16
Filed: 1987-01-13
Abstract: For secure gripping of rows of blocks of different lengths and with neighbouring blocks spaced apart from one another to a greater or lesser extent and for vertical positioning of such rows of blocks on existing masonry structures without laterally projecting gripper parts, the invention proposes grippers which comprise two parts, which can be displaced relative to one another in terms of length, and exhibit an angle lever which, via its longer lever arm, is pivotably mounted on one gripper part and, via its other lever arm, is in engagement with a vertically directed guide track which is arranged on the other gripper part. The hoist, adjusting itself automatically into a load centre point, acts on one lever arm of the angle lever such that, on the one hand, the hoist always acts in the load centre point of one arm of the angle lever, but the latter, on the other hand, displaces the two parts of the grippers relative to one another until such time that the neighbouring blocks of a row of blocks rest one against the other on the end sides, even if a large gap is located between two neighbouring blocks of the row of blocks, such as is the case when receiving a row of blocks from two pallets. <IMAGE>
Patent DE-3703612-A1 (DE)
Title: High compression internal axis rotary internal combustion engine
Inventor: OPEL FRITZ
IPC: F01B13/00
Filed: 1987-02-06
Abstract: The proposed rotary internal combustion engine relates to such an engine in a circular enclosing body with uniformly rotating piston drum and an eccentrically supported shaft, the middle part of which between the points of support is of square design, on which shaft with a paired sleeve valve piston linearly guided in the piston drum two working chambers without dead space are formed, a complete two-stroke working process being achieved in each during one revolution. The fuel is injected directly into the compact combustion chambers during the compression, all the air flowing into the compact combustion chambers through quench areas and efficient mixing with the fuel being achieved by strong swirling. Compression can take place into the economically favourable range. Ignition is performed by a glow plug or spark plug. The centrifugal forces cancel one another out so that additional balancing masses are not required. Exhaust and refill take place by way of free fresh air and exhaust paths, a directed outflow through a ducting piece producing a suction effect, as a result of which some fresh air, with the scavenging effect of the working chambers, flows out with the exhaust gases. A supercharger can be used for improved filling of the working chambers.

Title: Method and arrangement for utilising the waste heat arising in a coal gasification process when coupled with a gas and steam turbine combined cycle
Inventor: SPINDLER KLAUS DR ING
IPC: F01K23/06
Filed: 1987-05-05
Abstract: In a coal gasification plant (1), fuel gas is generated, which is passed via a raw-gas pipe (13) through the primary sides of several heat exchangers (20, 14, 4) into a purification plant (5), and after being reheated in one (4) of the heat exchangers, is used as fuel for a gas-turbine plant (2). The combustion air for the gas-turbine plant (2) is preheated in another (20) heat exchanger by heat exchange with the raw gas in a high temperature range. In this way, the waste heat arising in the coal gasification process is supplied to a large part to the gas-turbine section of the cycle, and not just to the steam-turbine section (3). <IMAGE>

Title: Method for separating off light materials, in particular plastic parts, from substrate mixtures and apparatus for carrying out the method
Inventor: WEINMANN ALFRED DIPL ING DR
IPC: B03B9/06
Filed: 1987-05-27
Abstract: The invention relates to a method for separating off light materials, in particular plastic parts, from, if applicable disintegrated, in particular wet-ground substrate mixtures, preferably waste material fractions or pre-sorted refuse fractions, in which the substrate mixtures are subjected to gravity separation in a sink-float basin and the floating light-material phase is removed and afterwards, if applicable after drying, subjected to further processing and is characterised in that the substrate mixtures subjected to the gravity separation are acted upon by liquid jets during their residence in the sink-float basin. The apparatus for carrying out the method is characterised in that at least one, preferably a number of jet nozzles is arranged in particular above the sink-float basin, with which nozzles liquid jets can be sprayed onto the substrate mixtures in the sink-float basin.

Title: Short-stroke push-button switch (pressure switch)
Inventor: MOTSCH ALFONS DIPL ING
IPC: H01H13/06
Filed: 1987-06-26
Abstract: The invention relates to a contact switch or push-button switch especially for use in the open air, which initiates an electric motor, a pneumatic or hydraulic operating process in the event of brief finger pressure on an approximately disc-shaped push-button element. Instead of the vulnerable thin push-button films which were normal in the case of such switches known until now, and were either bonded on or clamped in on sealing rings, the push-button element (6) is in this case cast as part of the switch housing (2), has a robust material thickness and is sufficiently elastic in the switching stroke direction as a result of one or more annular bulges (63). Switching is carried out via a push-button switch (14) which is installed in the opposing switching part (4) of the switch housing and whose switching button (15) projects out of the opposing switching part. This measure ensures electrical isolation of those switch parts (6, 15) which can be operated manually from the live switch part (14, 17). As a result of the fact that the air space (10) located between the push-button element (6) and the mating switching part (4) is connected to a highly elastic flexible tube (11) which projects into the interior (12) of the switch and is closed at its free end (13), the air pressure in the air space (10) remains constant throughout the standard temperature range (-30@C to 80@C) and the switching stroke path is in consequence always of the same length. <IMAGE>

Title: Heating plant control method, in which a rough regulation of the heating inlet temperature that can be achieved by on/off operation of the heat source is performed
Inventor: MAGORI VALENTIN DIPL PHYS
IPC: G05B13/04
Filed: 1987-09-29
Abstract: A heating plant control method, in which a rough regulation of the heating inlet temperature that can be achieved by on/off operation of the heat source is performed in such a way that the room temperature of the room(s) to be heated is not involved directly in the control process, but is used instead for long-term optimisation of the characteristics of the control system. Programmed heating cycles take place, oriented to the heat loss of the room(s) to be heated; the respective amounts of heat required according to the weather conditions are determined experimentally and recorded. Personal temperature wishes can be incorporated in the control process by entering information on the desired temperature in the control system in addition to the information on the actual room temperature, preferably by actuating a regulating means (S), for example a rotary knob, in the "Hotter" or "Colder" direction. A simulation model of the dynamic behaviour of the heating plant concerned is stored in the memory of a computer (C) as the basis for optimum regulation by collecting and correlating empirical data to form an experience estimate. Precise measurement of the amount of heat is performed by means of heat counters (W), whose results are incorporated in the control system as feedback on the actual amount of heat supplied. <IMAGE>

Title: Damping device for reducing the transmission of oscillations produced by vibrating apparatuses to the hand-arm system
Inventor: CHRIST EBERHARD DR
IPC: B25D17/04
Filed: 1988-03-22
Abstract: The subject of the invention is a damping device for reducing the transmission of oscillations produced by vibrating apparatuses to the hand-arm system. The invention is to be allocated to the area of "damping devices for mechanical oscillations", in particular in the case of intensely vibrating hand-held apparatuses. For the loading of the hands and hand-arm system, oscillation components in the frequency range below 60 Hz are particularly damaging to health. The damping devices disclosed hitherto display only inadequate damping properties in this particularly important frequency range. The subject of the invention is a device which also heavily damps the oscillations in the frequency range below 60 Hz. This is achieved in that gripping surfaces made of dimensionally stable material are coupled to the apparatus via a viscoelastic material layer over as large an area as possible (composite system). The good damping behaviour in the low-frequency oscillation range results by using a soft, viscoelastic material as coupling layer. The main area of application for the subject of the invention is the oscillation damping of hand-held apparatuses and tools.

Title: Apparatus for the extraction of gas from graves
Inventor: FABRITZ GERHARD
IPC: E04H13/00
Filed: 1988-04-23
Abstract: The invention relates to an apparatus for the extraction of gas from, and the ventilation of, in particular, deep graves. These are provided nowadays for reasons of space, in order to be able to carry out a number of burials one above the other. Owing to the high earth layer, the oxygen supply to the grave is prevented and the rotting process up to the partial mummification of the buried person is interrupted. The apparatus represented in the drawing supplies oxygen to the grave and channels out any gas which has been formed. According to Figure 1, the apparatus comprises a pipe which is bent to form a U and has legs 1 of equal length, a straight base 2 with bores 3 introduced therein, and covers 4 at the end of the legs 1. According to Figure 2, the base of the U is bent in the form of a coffin lid, the apparatuses or the pipes are filled with coal 5, preferably an adsorption coal. The covers 4 are configured such that they do not close off the legs 1 in a sealed manner, but permit a gas/air exchange when the apparatuses are set up beneath or on top of the coffin and gases escape through the bores 3. <IMAGE>
