Title: Axial thrust safety clamp - has U=shaped locking piece with arms, and outward bent pieces
Inventor: AUSPRUNG ERICH
IPC: F16B21/18
Filed: 1989-05-08
Abstract: The axial thrust safety clamp has a U-shaped clamp locking piece with spaced-apart arms (1,2) pushing radially into a peripheral groove in the machine component being secured. A fastening joined to the locking piece holds the clamp on the machine component. The locking piece arms (1,2) have outward-bent pieces (19,21) so that their outer edges (4,7) are in a staggered position in relation to the inner edges (5,6) so that they are further from the fastening than the inner edges. The bends (19,21) are such that the outer parts of the arms (1,2) are bent along a lengthwise line (8,9). The angle between the inner and outer parts of the arms is about 170 deg. USE/ADVANTAGE - The arms of the locking piece belonging to the axial thrust safety clamp compensate for play resulting from high axial forces.

Title: Activated sludge vessel aeration and agitation system - central propeller delivers liq. downwards and stationary vanes located parallel to banks of aeration elements prevent rotation of liq.
Inventor: KIESSLING EGON HANS
IPC: C02F3/20
Filed: 1989-06-05
Abstract: An activated sludge tank has a flat bottom, an aeration device located just above the tank bottom, a vertical agitator shaft turned by a drive mounted on a support bridging the tank top, and an agitator propeller which circulates the liquid in the tank. The propeller delivers the fluid downwards, and guide vanes are provided which are approximately vertical, are arranged approximately radially to the agitator shaft, whose lower edges are a little above the lower edges of the aeration systems and whose upper edges are sufficiently high to prevent the liquid rotating about the agitator shaft. The aeration device is provided with outlets which are arranged in gps. lying parallel to the vanes and offset slightly from them in the direction of rotation. The aeration outlet gps. are arranged in a rectangular plan. USE/ADVANTAGE - Used in systems for clarifying waste waters.  A simple and inexpensive system is provided which is easily fitted to existing tanks, and operates successfully and efficiently. These advantages arise principally from the downward delivery of the agitator propeller and the prevention of the rotation of the fluid body.

Filed: 1989-12-18
Abstract: A method for detecting the presence or the dimensions or the correct position of a workpiece (16), which is clamped in the main chucking device (15) of a numerically controlled machine tool, relative to which a constructional part (19) is arranged displaceably, a desired position value (3) being predetermined for a displacement of the constructional part (19) in the direction of the workpiece (16), and the actual position value (11) of the constructional part (19) being continuously determined iteratively, is to be developed in such a way that the desired determination is possible at a lower outlay. This is achieved in that the desired position value (3) for the displaceable constructional part (19) is selected so that, in the absence of a workpiece (16,28), a stop (17,27) for the workpiece (16,28), said stop being an integral part of the displaceable constructional part (19), would be moved to a location which, in the presence of a workpiece (16,28), is within this, and in that a signal is generated when the difference between two successively determined actual position values (11) falls below a predetermined limit value and the desired position value (3) is not reached.

Inventor: KNIER GUENTHER G
IPC: H01R4/64
Filed: 1990-07-31
Abstract: A locking clamp is known, with which a wall trunking covering part can be held in a wall trunking lower part. At the same time, this locking clamp has a contact tip, constructed as a cutter, in order to scratch insulating varnish layers and thus facilitate an electrical connection between the covering and lower part. Fault-free scratching cannot reliably be achieved using this clamp for thick and/or hard insulating layers. In the new locking clamp (10) a contact lug (11) is provided which has a plurality of contact cutters (13, 14, 15) arranged one behind the other in the insertion direction (A) of the covering part (30). The subsequent contact cutters (14, 15), which move along in the same scratching track during pushing-in, thus ensure an electrical connection in every case, even in the case where the front contact tip (13) is blocked with material which has been lifted off or has not completely scratched through the insulating layer.

Title: Mobile breaker plant - breaks large-sized material down into fine particles of varying granular sizes
Inventor: SCHOOP GUNTHER-DIETMAR
IPC: B07B1/00
Filed: 1990-12-15
Abstract: The rough material is fed by two chain conveyors spaced apart and parallel to one another to two parallel breakers. Between the two conveyors (8,21) is saddle-shaped bar grid (4) on to which the raw material is transferred. Beneath the bar grid is a fine material conveyor (32) for collection of fine material falling through the grid, and at the exit of the breaker plant a conveyor belt (17) is provided to take the fine material away. On approaching the breakers, the conveyors transfer the raw material firstly to a issuing box, along one long side of which is the bar grid tilted upwards and outwards, and beneath which is the conveyor taking away finely decomposed material. The breaker equipment is mobile on a continuously revolving track system or, alternatively on tracks, and to transfer the raw rough material onto the bar grid (4) a pivotable arm of a blade wheel digger is used. USE - To break down rough, large pieces of material into small particles of varying granular sizes.
