Title: Sheet transport suction roller control for printing machine - has logic circuit between machine, control and suction jet cleaning control
Inventor: SCHULZ HORST
IPC: B41F23/06
Filed: 1989-11-23

Title: Press with continuous drum-driven steel bands - has metallic or ceramic friction layer on driving drums
IPC: B30B5/06
Filed: 1990-06-26
Abstract: A continuous press for the manufacture of chip board or other pressed board has endless steel bands (2) driven by drums (4), at least one of which is heated.  Between the surface (5) of the drum and the steel band (2) is an adaptive layer to satsify the  mechanical and thermal requirements.  The surface layer can be metallic or ceramic and applied by plating, spraying or sintering.  Alternatively it can be formed by attaching tiles or a separate endless friction belt can be interposed. The walls (5) of the drums (4) are made of smooth steel sheet modified by a surface treatment which increases the friction without being affected by thermal expansion.  The surface treatment depends on whether the drum is heated and good thermal conduction is required or whether it is unheated and good insulating properties are needed. USE/ADVANTAGE - Slippage between the driving drum and the steel bands is avoided and wear is reduced.

Patent DE-4109732-A1 (DE)
Inventor: KRATZ GUNTHER
IPC: B01D53/00
Filed: 1991-03-25
Abstract: The invention concerns a process for cleaning exhaust air containing biodegradable contaminants which are only slightly soluble in water. The contaminants are absorbed by a washing liquid containing activated sludge and at least one high-boiling solvent for the contaminants and are decomposed by the activated sludge. The solvent and the activated sludge are separated from at least part of the remaining washing liquid which is then drained off. In order to reduce significantly the amount of substances which are dangerous to the environment or to health in the washing liquid separated off, without making it necessary to take costly additional measures, it is proposed that the part of the remaining washing liquid be separated off by membrane filtration using inorganic or hydrophilated organic membranes. Silicone oil is a particularly suitable solvent for use in the process.

It also has to ensure that all parts of the transport arrangement can be made heat-resistant and, in addition, can be thermally insulated. USE/ADVANTAGE - The system enables heavy loads to be deposited on to a burning oil-well to facilitate and save time in preparations for extinguishing the fire.
Patent DE-4112259-A1 (DE)
Inventor: GABRIEL JOCHEN
IPC: A61M5/315
Filed: 1991-04-15
Abstract: The injection device proposed comprises a housing (11, 21) designed to hold the liquid to be injected. Fitted in this housing is a plunger (29, 38) which can be moved longitudinally. When injecting, the plunger is displaced between an active position and an inactive position, thus pushing the liquid (13) out of the housing. A control member (23) is fitted, by means of which the effective length of the plunger (29, 38) can be altered. In the inactive position, the plunger-length adjustment mechanism using the control member (23) is not activated, and hence adjustment of the dose is not possible in this position. Operator errors are therefore avoided.

Title: Rolling of profiled grooves in plastic material - has roll with projection to produce an indentation which can accommodate displaced material
Inventor: BORGMANN HEINZ
IPC: B28B11/08
Filed: 1991-12-04
Abstract: Profiled grooves (2) are rolled into opposite sides of a plastic material (4) by paired roll sets (8, 10). A second paired roll set (14, 16) produces grooves in the remaining two sides as the material is pushed through by handling devices (30, 38). At least the rolls (24) of one row (8) of the first set have a radial projection (26) arranged to produce an indentation at the end of the groove away from the second set (12) of rolls (14, 16). The roll projection can be a rounded nose. A backing roll (20) can be opposite the roll which has the projection. USE/ADVANTAGE - The indentation produced by the roll projection provides a space for the ridge normally produced at the final roll exit, giving a clean profile on all sides. It is particularly useful for shaping clay for ceramic blocks.
