Title: Multi-screw homogenising extruder - with intermeshing disc section to restrict axial flow
Inventor: BLACH JOSEF A
IPC: B29C48/03
Filed: 1978-01-19
Abstract: Screw machine for processing solid, liq. and high viscosity materials, consists of >=2 intermeshing screws in a housing, which rotate in the same direction. The shafts carry a series of axially-spaced plates which deviate from concentric circles and rotate in housing cavities in the form of overlapping concentric circles. Between >=2 adjacent plate sections on one shaft is provided a circular ring, concentric with the shaft and only slightly smaller in o.d. than the housing. Axial movement of the material past the non-circular plates is prevented, forcing all material to pass through the combed zone and move from one screw to another. Material treatment is more uniform and homogeneity is improved.

Patent DE-2829554-A1 (DE)
Inventor: DAETWYLER FRITZ
IPC: G08B17/00
Filed: 1978-07-05
Abstract: Fire detection system having a multiplicity of fire detectors (A11, A12,... B1, B2,... C1, C2,...) connected to a signalling centre (S). The individual fire detectors are arranged in groups (A, B, C...) according to protection areas (I, II,...), the detectors of one group being connected to one another and to the signalling centre (S) via a group line in each case. To increase the immunity to false signals, each protection area (I, II,...) is passed through by its own fire detector group (B1, B2,... C1, C2...) and by a selected fire detector group (A11, A12,... A21, A22...), common to some or all the protection areas. As a result, the installation expenditure and the susceptibility to faults can be kept particularly low. In the case of an expedient further development, the fire detectors (A11, A12,... A21. A22...) of the group (A) common to all the protection areas (I, II,...) respond to a different consequential effect of fire than the fire detectors (B1, B2,... C1, C2...) of the separate groups (B, C...) assigned to the individual monitoring areas, as a result of which the immunity to false signals can be further improved. This so-called two-group dependence can also be used analogously for increasing an alarm level, in that if one detector of only one group responds, a preliminary warning signal is triggered and, if detectors in two groups respond, the actual fire alarm is set off. <IMAGE>

Title: Regenerating absorption medium by hot gas - with part of flow diverted to heat container exterior
Inventor: WIESSNER FRANK DIPL ING
IPC: B01J20/34
Filed: 1979-08-30
Abstract: In the thermal regeneration of an absorption medium by passing hot gas through the medium container, part of the gas flow (10- 25%) is diverted round the outside of the container to produce a more uniform temp. throughout the medium. The container is enclosed in a casing with an intermediate space contg. an inlet and an outlet for the diverted gas. The casing is lined with heat- insulating material. The high temp. differences between the centre and edges of the adsorption medium (up to 100 deg.) and due to radial heat losses which occur in known hot gas regeneration systems, in addition to differences in the flow direction, are largely avoided, resulting in energy economy and the possibility of using cheaper structural materials.
