Title: Steel band punching tool with holding-down device
Inventor: BENDEICH EDWIN
IPC: B26D7/02
Filed: 1993-02-11
Abstract: The invention relates to a steel band punching implement with a holding-down device, in the case of which the punching tools (2), which are held in a base plate (1), are surrounded by a compressible, elastic intermediate layer (1') which is applied to the base plate (1) and by a dimensionally stable covering layer (1'') which is applied to the intermediate layer (1') and serves as a holding-down device. Application of the intermediate and covering layers may be carried out by means of bonding, but in particular by means of pouring on. The base plate (1) may also be cast. To achieve this, the individual punching tools (2) are fixed to an assembly plate (9). The individual punching tools (2) have, to improve distribution of the liquid plastic compounds, holes (4) and/or slots (5). A frame (10) prevents the flowing out of the plastic compound(s) and may determine the thickness of the base plate (1) or the base plate (1) and the intermediate layer (1'). In order to improve distribution of the plastic compound, a fluxing agent may be used which reduces the surface tension, and/or the assembly plate (9) may be mounted against or on a vibratory device (12). Premachining and/or pouring out may be carried out by robots in a computer-controlled fashion. <IMAGE>

Inventor: BREITWEG WERNER
IPC: B62D5/083
Filed: 1993-03-31
Abstract: A rotary slide valve (1) for power-assisted steering of motor vehicles contains in a valve bore (5) of a valve cage (2) a rotary slide (4) linked to a steering shaft connection (23). A control bushing (7) can swivel over a limited angle in an axial bore (6) of the rotary slide (4). The rotary slide (4) has control longitudinal grooves (20) arranged in its axial bore (6) that cooperate with control longitudinal grooves (21) on the outer surface of the casing of the control bushing (7). The internal control bushing (7) is manufactured by a non-cutting forming process and can thus have relatively small dimensions. Both the control longitudinal grooves (21) and the control edges of the control bushing (7) may be manufactured by such a process, for example by cold forming. Thanks to the relatively small dimensions of the control bushing (7), the whole rotary slide valve (1) may be very compact.

Patent DE-4415542-A1 (DE)
Title: Centrifugal liquid filter
IPC: A47L9/18
Filed: 1994-05-03
Abstract: The centrifugal fluid filter holds the filter fluid in a rotating container, pressed by centrifugal force against the outer wall, in a fixed position. The dust or dirt-polluted gas is introduced into the filter fluid via a central pipe which is fixed to the container and also forms the spindle through branches in the central pipe. The gas is purified and leaves the system through outlet apertures in the central pipe. This equipment is thus position-independent and insensitive to movement.
