Patent DE-3246232-A1 (DE)
Inventor: BLEECK JOERG DIPL ING
IPC: C01F11/18
Filed: 1982-12-14
Abstract: The invention relates to a process for wet grinding of natural and/or synthetic carbonates in wet suspensions in which the viscosity of the mass is decreased and a favorable particle size range distribution is obtained having a small portion of very fine overground particles. The carbonates in the wet grinding are mixed with zeolites to 0.05 to 3.0% by weight based on the dry weight of the carbonates. Chemical dispersants are used to help effect the process.

Title: Precast reinforced concrete unit with anti-slip and anti-tilt wedge with recessed openings for grouting the body joints - especially suitable as a retaining wall
IPC: E02D29/02
Filed: 1983-02-23
Abstract: The reinforced concrete heel integrally concreted in place beneath the precast retaining wall unit serves as a shearing and tilt wedge. The recessed openings over the longitudinal joint ensure adjustment and fixing by wedge during installation. Advantages of this retaining wall as a precast reinforced concrete unit are:     - no slipping in the base joint   - no tilting through excessive compaction during installation   - immediate placement of the earth masses possible   - no support necessary during placement of the earth masses - no support of the precast retaining wall units is necessary even in the event of subsequent exposure on the air side down below the slip joint. g

Title: Stone crusher for the comminution of stones
Inventor: LUDWIG HELMUT
IPC: B02C21/02
Filed: 1983-11-23
Abstract: To improve the floors, avoid damage to the machines and reduce the manpower needed it is necessary to comminute the many stones for gravel or crushed stone floors by means of a stone crusher. The "Müller system", which is up to now the best invention on the market, is very expensive to procure and operate, and moreover the "Müller system" is an integral stone crusher and machine, which can only be operated by skilled personnel. My invention is based on the need for a system which is very economical and shows little wear, the stone crusher being operated and pulled by a tractor, is simple in assembly and can be operated even by agricultural labour with no special training. The useful effect of my system is to be compared with the Müller system.

Title: System arrangement for electric signal transmission and signal processing
Inventor: VUUREN DANIEL NICOLAAS JANSEN
IPC: G06F13/22
Filed: 1984-04-19
Abstract: The multiplicity of currently available radio transmission methods and the adaptation to specific radio conditions require a multiplicity of different device types which render economical manufacture increasingly difficult. Taking into account a modular design comprising independent functional units (E1, E2,...En), it is proposed to allocate a control unit (ST) which is common to all functional units to a universal processor (UP) which interacts with a highly flexible bus (flexibus) via an interface (IO). The functional units are in turn connected to this flexibus (FB) via interfaces (I1, I2,...In) which in each case form an integral part of the functional units. The most widely differing device types can thus be implemented via corresponding combination of functional units in a structural unit (SYS-G) which is always equipped with the same control unit and the same flexibus. <IMAGE>

Title: Device for supplying pressure medium to a machine, in particular a hydraulic cylinder
Inventor: MUTSCHLER GERHARD
IPC: F15B11/08
Filed: 1984-05-25
Abstract: In machines with large pressure differences between the working feed and the rapid-traverse motion, a two-circuit control system with a high-pressure pump and a low-pressure pump is provided. The change-over from working feed to rapid-traverse motion or vice versa is effected by a proportional directional control valve which is constantly attached to the high-pressure and low-pressure line via a restrictor or a non-return valve. The cost can thereby be substantially reduced. <IMAGE>

Title: Locking apparatus for the filter plates of a filter press
Inventor: BUSSE OSWALD DR ING
IPC: B01D25/172
Filed: 1984-07-25
Abstract: The filter plates (1, 2, 3) of a filter press are locked together by means of a locking hook (15) mounted on each filter plate or a locking pin (20) which engages neighbouring filter plates. The filter plate (3) preceding these plates (1, 2) carries a latching element (24), engaging below the locking pin, having a stop cam (22) pivotably mounted against spring tension, which only releases the locking hook (15) for its opening movement when this preceding filter plate (3) is removed on opening the press. The release is further delayed by an additional rigid lug (31) of the latching element (24) until the filter plate which has been removed has also overcome the filter cake adhesion. <IMAGE>

Title: Clarification tank for water treatment without movable clearing mechanism for the deposited sludge
Inventor: MAENNCHEN WIPRECHT DIPL PHYS
IPC: B01D21/02
Filed: 1984-08-20
Abstract: A clarification tank is described which contains no movable mechanism and is suitable in particular for the secondary clarification in waste water purification in activated sludge plants. For any desired length, the clarification tank has a V-shaped cross-section, which, at the base of this V in the longitudinal direction is furnished with a deep slot having a sawtooth profile so that sludge depositing in the clarification tank in the clarification process collects in part in the slot in the depths of the sawtooth profile and from there can be removed as required. In the extreme case, the sawtooth profile is composed of only one funnel. Rod-shaped internals can be immovably arranged in the slot which, by their relative motion to the sludge during the downwards movement of the sludge in the slot to the withdrawal point, fulfil the same purpose as the slowly rotating rakes in the known tanks for thickening sludge.

IPC: F16D67/02
Filed: 1985-02-09
Abstract: The winding shaft (1), which can be driven by an electric motor, for example of a roller shutter can be operated manually when the motor (3) is not powered. The motor/drive unit (3, 4) is a component of an insert (2) which can be arranged within the winding shaft (1) and is stationary when the motor is operating. An anchor part (19) which is spring loaded against the magnetic force is seated on the motor shaft (5) such that it is fixed in rotation and can be displaced axially in the region of the motor magnetic field. Said anchor part has a first brake disc (21) which is located opposite a fixed-position second brake disc (22). When the motor is not powered, the first brake disc (21) is pressed against the second brake disc (22) in a rotationally fixed manner, and is lifted off it when the motor is powered. The second brake disc (22) is furthermore supported such that it can rotate and can be driven from the outside via power transmission means. A blocking device (24) is connected in the power transmission means and, in its effective position, prevents rotation of the second brake disc (22) while allowing said brake disc to rotate when it is in its ineffective position. <IMAGE>
