Patent DE-2120319-A1 (DE)
Title: Hot gas drier - for fibrous materials and wooden shavings
IPC: F26B17/10
Filed: 1971-04-26
Abstract: The drying of coarse and fine vegetable fibres and wooden shavings is accomplished with an inert mixture of hot gas and superheated water vapour and two sieving stages and dryers. The finer constituents are separated in the first sieving stage, dried if necessary and then separated from the carrying gas. The coarse and middle constituents are separated in the second sieving stage and dried with the inert gas mixture. A part of the outlet gas is returned to be heated again and the remaining part goes to the exhaust. The ratio of these two streams depends on the final moisture content desired and also the proportion of the coarse fraction in the feed. The temperature of the hot gases is controlled depending on the temperature of the outlet gases. A combination of thermostats and hygrometers help control the burner which heats the gas stream.
Patent DE-2121894-A1 (DE)
Title: Centrifugal separator - comprising cyclone with fabric filter
IPC: B04C9/00
Filed: 1971-05-04
Abstract: The centrifugal separator consists of a cylindrical upper part and a conical bottom with a hollow type fabric filter parallel to the cyclone body but eccentric to the main axis, suspended from the top collar. The gas contg. the solids enters tangentially in the upper part and moves along the sides in a downwards spiralling motion. The dust collects on the filter cloth loosely without choking and this effect is increased by the wavy motion of the gas stream. In another variation the filter consists of a number of cylindrical parts arranged eccentrically to the main axis.

Title: Increasing response rate and stability of light-sensitive film - contg spiropyran and HX donor by reducing water penetration or content
Inventor: ARNOLD GUENTHER DIPL PHYS
IPC: G03C1/76

Title: Filter for liquids - using magnetic particles supported on iron grid, with electrical heating
Inventor: SATO KOZO
IPC: B01D35/06
Filed: 1974-05-08
Abstract: Liq. filter has a perforated metal support plate, which can be electrically magnetised, upon which magnetic metal granules or powder are piled up as a filter medium. The surfaces of the metal particles are so treated that they are chemically inert and corrosion-proof while still retaining their magnetic props. The bed is electrically heated. The matl. is heaped up in such a way as to give the max. possible surface area. The bed is maintained in the form of a heap by the influence of the magnetic field issuing from the support grid. This enhances the surface area and thus improves filterability and life. The use of heating in the bed means that the bulk liq. itself does not have to be heated.

Title: Axial positioning of centrifugal compressor - compressor shaft is positioned by controlled oil pressure acting on a radial flange
Inventor: SWEARINGEN JUDSON S
IPC: F16C32/06
Filed: 1974-07-12
Abstract: Centrifugal compressor runs in an involute chamber and is supported by and overhung from a driving shaft which runs in two axially spaced apart bearings. Between the two bearings is a chamber in which a pair of radially extending flanges attached to the shaft rotate. The end walls of the chamber each face a respective flange and are spaced therefrom by respective spaces. Pressurised oil fed to the bearings via oil ways accumulates in the spaces and escapes between the flanges and circular rims formed on the chamber walls. A pressure regulator controls the relative pressures in the two spaces and thus regulates the axial position of the shaft and the compressor rotor. The pressure regulator may be responsive to the load on the compressor as sensed by a measuring device.
