Patent DE-2736549-A1 (DE)
Title: Thermal treatment of viscous material e.g. gluten - in injection drier through two-jet nozzles in particle laden hot air
Inventor: FEMERS KURT W
IPC: F26B3/12
Filed: 1977-08-13
Abstract: In the thermal treatment of pasty and viscous material of the consistency of soft rubber, e.g. wheat gluten, the material is injected in a dryer into a flow of hot air, laden with already dried particles of 10-500 mu particle size. Monopumps (RTM) take the material at 1.55-5 bar to a two-jet nozzle, where compressed air at 2.5-7 bar effects the injection into the hot air stream which flows at 20-30 m/s velocity. The arrangement results in a gently and brief drying action of the wheat gluten. IF the air cooling is not sufficient to prevent all deposit formation, water can be readily fed to the nozzles.

Title: Corona discharge pretreatment device for valved plastics sacks - for printing, uses electrode which is lifted from support roller to allow bag to pass
IPC: B29C59/10
Filed: 1978-02-16
Abstract: Device for corona discharge treatment of valved plastics bags preparatory to printing upon them, features a discharge electrode which is lifted by a cam control from a carrier roller as the valve and the bottom of the bag moves past it. This lifting distance is greater than that min. distance necessary for the corona discharge treament. Used for improving adhesion of printing ink to bag. Normally the gap between electrode and carrier roller is 0.8-1.5mm which is not enough to allow a bag with valve and bottom to pass, so that such bags could not be corona-treated in prior mfr. This disadvantage is removed, in simple fashio, by the device described.

Title: Dislocations free silicon single crystal pulling device - with seed crystal mounted on slide for lateral displacement by external motor
Inventor: REUSCHEL KONRAD DIPL CHEM DR
IPC: C30B13/32
Filed: 1978-06-28
Abstract: The zone melting device has rotating holders for the silicon bar and for the seed crystal inside a vacuum vessel.

Title: Prodn. of porous rubber articles - using eutectic mixtures of urea-acetamide-emulsifier which are homogeneously distributed
Inventor: BAUER ARMIN DR ING
IPC: C08J9/10
Filed: 1978-08-12
Abstract: Porous rubber articles are mfd. using a mixt. comprising (a) 33-95, esp. 55-90% urea, (b) 5-67, esp. 10-30% acetamide, and (c) 0-50, esp. 5-20% of an emulsified, the sum of these components being 100%. The acetamide forms a entectic mixt. wiht the urea and has a lower m.pt. than that of urea itself, with a reduced tendency to crystallisation. The urea is thus homogeneously distributed in the rubber, unlike other urea-contg. mixts.

Title: Pivoting vane rotary pump for viscous fluids - has vanes proportioned to form constant seal between inlet and discharge ports
IPC: F04C2/44
Filed: 1978-10-20
Abstract: The pump has a rotor (42) with radial arms (34) each of which carries a pivoting vane (19). An insert (16) in the stator narrows the annular gap (14) between the rotor and stator between the inlet and discharge ports (12, 13). The vanes are carried on bearings projecting axially from the working space and running in a guide which causes the vanes to pivot as they pass the narrow section (16) to form a seal. The length of the insert and the circumferential distance between the vanes are such that one vane seals the section just as the previous vane is leaving it.
