Title: Insulated cable for safety switch - avoids adverse effects caused by crushing of cable and shorting of wires by using controlled shorting to operate fuse and de-excite relay
Inventor: RAPP WERNER DIPL ING
IPC: H01B7/32
Filed: 1989-12-22

Abstract: Assembly consists of a large cylindrical or prism-shaped mixing container narrowing to a funnel at the base, at the centre of which a central pipe conveys dried products from the bottom upwards for mixing by recirculation. The novelty is that the descending flow of ingredients is divided into two, one of which is recirculated and further mixed, and the other is removed from the mixer. Pref. powder or coarse grained bulk solids brought together in a bulk mixing container descend to the funnel-shaped base where the flow (M1) is divded into two (M2, M3). One flow (M2) is returned to the top of the container by a pipe (17) while the remainder of the solid flow (M3) is drawn off through a removal unit (18). USE/ADVANTAGE - The assembly mixes powdery or coarse grained bulk solids. The assembly has the advantage that it integrates the processes of filling, mixing and removal of the mixed products such that these processes may be combined or not as required. This saves time and facilitates continuous operation.
