Title: Lathe
Inventor: DORMEHL ERICH
IPC: B23Q7/04
Filed: 1981-08-26
Abstract: In a lathe with a horizontal spindle, a work magazine (6) is arranged above the headstock (1). The work magazine (6) is designed for transporting the workpieces into a transfer position above the chuck (17) of the lathe. Furthermore, the lathe has a work transfer device (9). The latter has pivoting arms (10, 11) for gripping the reclining workpieces and for pivoting these workpieces into a position parallel to the chucking surface of the chuck (17). The pivoting arms (10, 11) of the work transfer device (9) have work grippers (13, 14) which are rotatably mounted at their ends and can be rotated by means of a pivot drive (15). The work transfer device (9) can work as an orientation station so that it is then necessary to move the workpieces to the chuck (17) by means of a work gripper (16) clamped in the drum tool magazine (5). Alternatively, however, it is also possible to make the pivot arms (10, 11) pivot through 270 DEG  so that the workpiece can be moved until directly in front of the chuck (17). In this embodiment, however, the work transfer device (9) must also be movable as a unit in the Z-direction. <IMAGE>

Title: Optical proximity switch
Inventor: HEIM ALFRED WILHELM
IPC: G01V8/12
Filed: 1981-09-23
Abstract: At least one light-emitting transmitter (23) and one receiver (24) which responds to the reflected signal of the emitted light are arranged in each case in a housing (10). The transmitter (23) is situated behind a cylindrical lens (20), as a result of which the conical propagation of the signals is converted into a region (B) in the shape of a sector of a disc. The receiving region of the receiver (24) is likewise converted by a cylindrical lens (21) into a region (C) in the shape of a sector of a disc. The overlapping disc sectors form the scanning region (B'). A complete panorama can be covered by juxtaposing a plurality of similar optical proximity switches. Reject controls for pressing, injection (spraying) and stamping (punching, blanking, piercing) machines, control monitoring for transport systems etc. are particularly advantageous fields of application for this switch. <IMAGE>

Title: Tank for reacting sludges which are to be dewatered with flocculants, especially for sewage treatment plants
Inventor: NIEMZIG HAJO ING GRAD
IPC: C02F1/52
Filed: 1981-12-02
Abstract: In a tank for reacting sludges which are to be dewatered with flocculants, a continuous adjustment of the flocculation time required is achieved by the possibility of altering the contact volume available between the inlet opening and the outlet opening by rotating or pivoting the tank. The tank is, in particular, designed as a horizontal drum which can be pivoted about an axis of rotation outside its long axis, with the outlet opening being located in the pivoting axis. This makes it possible to adjust the contact volume present in the drum, and thus the flocculation time, by pivoting it.

Title: Hydraulic pretensioning device for a screw connection
IPC: F16B31/04
Filed: 1982-10-08
Abstract: The hydraulic pretensioning device for a screw connection has a housing with a cylinder bore in which an annular tensioning piston is guided axially displaceably between a starting position and a tensioning position. The annular tensioning piston and housing define an annular pressure-medium chamber which is connected via a duct formed in the housing to a connection, situated on the outside of the housing, for an external hydraulic unit. A blow-off duct, one end of which is situated on the outside of the housing and the other end of which leads into the pressure-medium chamber or into the duct, is provided in the housing. The blow-off duct has a shut-off device which is dependent upon the position of the annular tensioning piston and opens the blow-off duct only when the annular piston is in the fully extended tensioning state.
