Title: Roller mill, in particular roll-type crusher
Inventor: JAKOBS WILLY
IPC: F16C13/00
Filed: 1982-03-30
Abstract: In roller mills, in particular roll-type crushers whose rollers are to be relatively long, it is difficult to connect the wear-resistant segments of the roller casing to the base body of the crushing roller in such a way that after a relatively short operating time premature fractures in the screws or even deformations and formations of stress fractures do not occur in the casing segments due to the expansion and bending stresses between the segments of the roller casing and the base body. According to the invention, this is avoided in that, in order to stress at least two casing segments arranged one lying opposite the other on the base body, base body and casing segments are provided with openings which are arranged flush one opposite the other and into which tubular or rod-shaped, elastically expandable connecting elements which extend transversely with respect to the axis of rotation of the base body and on which the clamping elements engage are inserted. <IMAGE>

Patent DE-3233046-A1 (DE)
Title: Electro-hydraulic control arrangement
Inventor: ZENKER SIEGFRIED
IPC: F15B11/042
Filed: 1982-09-06
Abstract: The invention relates to an electro-hydraulic control arrangement, with a hydraulic motor which can be acted upon in one direction of movement by a pressure-medium pump and from which the pressure medium is discharged under load in the other direction of movement via a volume-regulating valve, an electromagnetic two-position valve device which is connected upstream and can be changed over between a shut position and an open position as a function of the direction of movement, a load-holding retaining valve, and an electromagnetically adjustable volume-regulating valve for regulating the volume of pressure medium to be discharged into the tank during a movement of the hydraulic motor in one direction of movement. In known control arrangements of this type, a separate volume-regulating valve, which is controlled accordingly, is provided for each direction of movement. There is a general demand to reduce the number of components of such a control arrangement. This is achieved by virtue of the fact that the two-position valve device is arranged in parallel with the non-return valve in the working pressure line for the other direction of movement of the hydraulic motor, and that one and the same volume-regulating valve is used for both directions of movement, the operating magnet of which volume-regulating valve is connected in a circuit with the actuating magnet of the two-position valve device in such a way that the two-position valve device can be shifted into the open position only when the volume-regulating valve is displaced into the shut position. Although only one volume-regulating valve is now used, the hydraulic motor can be controlled in a sensitive manner in both directions of movement. The simplification in construction is considerable. <IMAGE>

Title: Process and device for extruding vegetable fragments, in particular wood fragments, mixed with binders
IPC: B27N3/28
Filed: 1983-06-20
Abstract: In the production of extruded products from vegetable, especially wood, fragments it is known to determine the chip orientation across the entire cross-section. By contrast, the object of the invention is to orient individual layers of the strand (1), preferably the outer layers (2, 3), differently from the centre layer (4). This is achieved with the aid of orientation slides (10, 11) which compact the composition (17) disposed in the pressing chamber (7) of the extruder (6) section by section corresponding to its thickness during a reciprocating opening movement. The backward movement is greater than the forward movement. However, the latter leads to a compression of the composition which has fallen into the chamber released and thus to an orientation perpendicularly to the pressing surface of the extruder ram (20). <IMAGE>

Title: Granular antislip belt
Inventor: DUERR BENEDIKTA
IPC: B60C27/18
Filed: 1983-12-20
Abstract: The granular antislip belt is intended to prevent car accidents with their consequences on roads covered with black ice and white frost. Pedestrians are to be prevented from falling by the granular antislip belt. The invention relates to a tough, tear-resistant and wear-resistant plastic belt (or hard rubber belt) possibly with incorporated steel wire cloth in the width of the tread of the corresponding car tyres, which steel wire cloth can be mounted around the tyre quickly (on the inside with a ring system) and securely on each car tyre with the aid of lateral tabs with eyes for holding tensioning chains (similar to snow chains). In the case of shoes, granular antislip belts are bonded onto the soles of the shoes. Very hard plastic grains (or gravel etc.) are welded in to the entire tough plastic outer layer so that a surface like a quite rough emery paper is produced. When the tough plastic outer layer is worn away, new hard grains always reappear which produce the required braking effect on black ice. Even when travelling up a hill the wheels of the car do not slip on black ice.

Title: Gravity mixer
Inventor: HAHN HORST DIPL ING
IPC: B01F5/24
Filed: 1984-01-19
Abstract: Mixing and homogenising of pourable bulk solids in silos is achieved by withdrawing material under the influence of gravity at different layer levels and mixing it in downstream mixing chambers. In order to simplify the process, a central mixing tube is installed, which has a plurality of partitions in a longitudinal direction and which takes in material at various bed levels and mixes it in the mixing chamber integrated into the silo. The mixing chamber and the central mixing tube are designed so as to be able to discharge displaced air or fluidising air into the upper silo space, without interfering with the material flow into the mixing chamber.

Title: Drive device for raising and lowering windows, especially for motor vehicles
Inventor: BANGLE CHRISTOPHER
IPC: E05F11/48
Filed: 1984-02-09
Abstract: A drive device for raising and lowering windows, especially in motor-vehicle side walls or doors, has an endless rope drive which engages on a driver connected to the lower edge of the window or carrying the window. A multiply deflected continuous belt band serves as a rope drive. At the same time, a portion of the belt band equipped with an actuating handle is arranged outside the constructional part receiving the window, in the horizontal direction or essentially in the horizontal direction, preferably on the top side of the constructional part and underneath the window. A drive device of this type for raising and lowering windows is characterised by only a few individual parts, a low weight brought about thereby and easy and simple operability. The particular advantage of the drive device is to be seen in the small amount of space which it requires. Useful stowage space for accommodating articles of luggage thereby becomes available in the lower part of the constructional part, for example a motor-vehicle side door, receiving the window.

Title: Combined gas/steam turbine power station with CO/O2 combustion
Inventor: GYARMATHY GEORG DR
IPC: F02C3/34
Filed: 1984-04-07
Abstract: In a combined gas/steam turbine power station with CO/O2 combustion one compressor each (35 and 36) for a CO/CO2 and an O2/CO2 gas mixture is directly driven by the gas turbine (31). The two gas mixtures are led into a combustion chamber (42), where the CO is partially burnt. The fuel gases flowing out of the combustion chamber (42) pass into a high-pressure part (32) of the gas turbine (31). A secondary compressor (43) delivers an O2/CO2 gas mixture distributed over a plurality of turbine stages into the high-pressure part (32), the O2 delivered by the secondary compressor (43) subjecting the residual CO present in the fuel gases to isothermic combustion. In a low-pressure part (33) of the gas turbine (31) the fuel gas is expanded adiabatically. In a heat exchanger (51) the thermal capacity of the expanded fuel gases is utilised for steam generation for a steam turbine assembly (52) thermally connected to the output of the gas turbine assembly. <IMAGE>
