Title: Internal recycle thermosyphon evaporator - in which the recycle tube has an annular sleeve taking the feed
Inventor: PARUSSEL HORST
IPC: B01D1/12
Filed: 1971-07-21
Abstract: Thermosyphon type recycle evaporator has a central recycle tube with vertical tube calandria between the tube plates. The recycle tube has an outer pipe forming an annular space into which a feed pipe discharges and which is blocked off from upper an separation space. There should be a single recycle tube with its coaxial jacket. The jacket is sealed at both ends into the tube plates. The recycle tube discharges into the jacket tube at a short distance above the latter's opening into the lower evaporator space. The arrangement combines the advantage of the external recycle by shielding the recycle tube from the heating medium and at the same time preheating the feed without any loss of thermal efficiency.

Title: Regulating filtering centrifuge - to keep thickness of filtered solids layer constant during continuous discharge
Inventor: PAUSE KURT
IPC: B04B11/02
Filed: 1971-10-15
Abstract: A continuously running filtering centrifuge with tapering drum and discharge of filtered solids at the wide end is operated as follows:- the solid material is throttled at the radial exit to form a flowing layer against the tapered inner filtering wall of the drum; an air jet is blown by a nozzle against this layer; the backpress of air in the nozzle varies according to the thickness of the layer of solids; the variation in this backpress actuates a pneumatic regulating valve which regulates the flow rate of incoming mixt. entering through a flexible tube valve; thus, with the discharge rate of filtered solids maintained constant, the supply of mixt. to the centrifuge is varied so as to keep the thickness of the layer of solids against the drum wall constant.

Title: Bleeder valved explosion door - eg for blast furnace gas collector
Inventor: MUELLER RUDOLF
IPC: C21B7/00
Filed: 1972-03-03
Abstract: Bleeder valved explosion door for the protection of gas-filled enclosures which present an explosion hazard, esp. blast furnace gas collectors, dust separators, etc., has two pistons and accompanying cylinders on a compression network.

Abstract: Procedure for stacking piece goods and removing them from the stack as well as for handling and storing piece goods in high rack stores by means of transport and storage plates by which empty storage and transport plates positioned on a roller track of the lowest floor of the stores are moved towards a lift by which they are lowered following each other in a loading position. The loaded plates are subsequently moved by the lift to a floor above the lowest floor and transferred from the lift on a roller track of that floor. During transfer of the loaded plates on the roller track all empty plates positioned already on the roller track are at the same time moved to a second lift located at opposite end of the floor by which they are lowered on the lowest floor and transferred on its roller track along which they are moved to the first lift to be lowered in the loading position.

Title: Consumption level sensitive electronic control relay - has binary and memory circuits controlling load circuit switching
Inventor: WENK JUERGEN
IPC: H02H3/42
Filed: 1974-07-09
Abstract: The relay, for general control purposes, is sensitive to some preset consumption level. The actual switching is part of a circuit block designed such that the system open circuits when the current drawn during some predetermined time period exceeds some given level, the measurement being made continuously during this period. Similarly the load is reconnected if it falls below the level. Measurement of load is by measurement of a series of pulses generated in proportion to the power consumption and a further series of constant pulses proportional to the preset load level. Two binary counters, a comparator and a memory circuit provide the actual relay control.
