Patent DE-3935849-A1 (DE)
Title: Plastic vessel for liq. or gas, suitable for large built-in fittings - has inner lining layer in several sections, i.e. shells, bonded together by e.g. welding
Inventor: KNAPPE HOLGER
IPC: B29C49/00
Filed: 1989-10-27
Abstract: Plastic container (I) for liqs. or gases is claimed, as  described in Pat. P3814699. The inner layer consists of several segments bonded together. The inner lining is formed of shells joined together by jointed membranes and/or seams produced by reflection welding, hot wedge pressure welding or friction welding. USE/ADVANTAGE - (I) is used esp. for the storage of hot aq. liqs., partic. as a hot water bath, and in liq. filters, dust  separators in gas streams, etc.. Modifying the lining from the original seamless type (P 3814699) gives a construction which is more suitable in cases where flanges, brackets, etc. have to be provided inside the container for the installation and replacement of baffles, filter plates, etc..
Patent DE-3942808-A1 (DE)
Inventor: BAYER FRANZ
IPC: E06B3/673
Filed: 1989-12-23
Abstract: In order to produce a spacer frame (2) containing a drying agent (1) for insulating glass panes, a hollow profile (3), which is initially free of drying agent, is bent several times to form the frame corners, but is left open at the final corner. Subsequently one, or appropriately both frame legs (5 and 7) leading to this open point can be filled with drying agent (1) and the frame (2) then finally closed. The frame leg (5) to be bent to form the final closure is first completely filled with drying agent, subsequently emptied from its still open front end (10) up to or beyond the bending area (12) and then bent over, so that no drying agent can hinder this final bending operation, and then connected by its open front end (10) to the other open frame leg (7). Thus, despite the fact that the frame is filled with drying agent, the bending operations are not hindered by drying agent. Even so, a very simple installation for carrying out this method is possible, because the hollow profile (3) can be removed from the filling device (8) after filling the still open frame legs and can be placed in the bending device; this may be the same bending device (13) which also carried out the previous bending operations. The emptying process up to the final bending area can be achieved with a combined sucking and blowing device, and carried out without the risk of removing too much drying agent (Fig. 5). <IMAGE>

Title: Water and abrasive mixer for surface cleaning - has inclined inlet for air and abrasive reduced in diameter to accelerate mixture
Inventor: SZUECS JOHAN DIPL ING
IPC: B24C5/04
Filed: 1990-01-31
Abstract: The mixer consists of a cylindrical mixing chamber (M) with a ceramic atomizer (18) at one end and a venturi form outlet nozzle (20) at the other. Water under pressure enters along the axis (24) through the pipe (12) and is atomized by it spassage through an aperture (19). Abrasive suspended in air enters the side of the chamber at an angle through a second inlet. The second inlet has a two-part bore (26) with a reduced section (26b) which causes the air-abrasive mixture to accelerate, thus promoting rotation of the mixture in the chamber. The spirally rotating jet creating as the mixture passes through the nozzle produces the desired wiping motion of the mixture on the surface ot be cleaned. USE/ADVANTAGE - Removal of fine layers of contaminated material from stone and metal surfaces, e.g. buildings, statues. Design effective with small nozzles.

IPC: C12Q1/6897
Filed: 1991-11-25
Abstract: A process is disclosed for screening substances having a modulating effect on a receptor-dependent signal transmission path in mammal cells. Test cells are used transformed with a reporter gene and with a regulatory sequence functionally linked thereto sensitive to the IP3/DAG concentration, as well as with a coding DNA for a receptor coupled to the phospholipase effector system, in particular a G protein-coupled receptor.
