Patent DE-4038471-A1 (DE)
Inventor: WERLE PETER DR
IPC: C02F1/50
Filed: 1990-12-03
Abstract: The direct dosing of aqueous solutions with acrolein as a microbiocide is problematic because of the associated laborious safety measures and the hitherto known use of reaction mixtures from the deacetalisation has proven not to be very economical. 
<??>According to the invention, aqueous solutions can be dosed in a simple, safe and economical manner with acrolein at a sufficient concentration level to be active as a biocide by cleaving acrolein acetals in the aqueous phase in the presence of a strongly acid deacetalisation catalyst into acrolein and the alcohol component, continuously removing the resulting acrolein from the deacetalisation mixture and transferring the acrolein into the aqueous solution to be dosed using an inert gas stream or a liquid jet pump with the aqueous solution to be dosed as the jet liquid.

Patent DE-4118893-A1 (DE)
Inventor: HAAS KARL-HANS
IPC: A47G7/04
Filed: 1991-06-10
Abstract: A flower box support for balconies is described, having a hook part (1') which encompasses the box and an angled parapet part (2'), which engages over the parapet and whose horizontal sliding leg (9') is displaceably and lockably connected to the hook part (1'). The principle section (6) of the hook part (1') has a supporting section at the upper end which is bent over at right angles. The object of designing the support as a cohesive system which is not merely held together by the screw is achieved in that the hook part (1') and the sliding leg (9') are inserted one into the other with positive fitting. The sliding leg (9') can be designed as a C-shaped profile or can be flat. In the latter case, the longitudinal slot in the sliding leg can have regular, mutually opposite edge cut-outs. <IMAGE>

Title: Facade panel mounting system - comprises glass panel bonded to profiled frame along long edges and having countersunk holes for screw fastening to frame
Inventor: HOEFLER FRANZ
IPC: E06B3/54
Filed: 1991-07-17
Abstract: A facade mounting system comprising a profiled framework supporting one or more glass panels which are bonded along the longer edges to the framework. The glass panel has a hole through it on both upper and lower edges. Each hole is centrally located between both the long edges. A conical countersunk profile at the opening to each hole, at least on the panel face away from the framework, enables a fastener to be inserted into the hole. The fastener, typically a countersunk head screw attaches the glass panel to the frame, and is strong enough to resist external force, e.g., wind when the adhesive fails. Silicone sealing cpd. is inserted into the holes to seal the gap between the screw and the hole. USE/ADVANTAGE - The facade mounting system is arranged in horizontal and vertical rows to support windows and glass cladding panels and prevents the panels falling away when the adhesive bond fails.

Title: Stacking machine for cut film sections - comprises two or more grippers independently moving on same track, with second gripper positioned for pick=up while first gripper completes stacking cycle
Inventor: HABERSTROH WALTER DIPL ING
IPC: B65H29/36
Filed: 1991-07-26
Abstract: Machinery for stacking film sections after the cutting stage consists of an endless conveyor belt followed by a gripper mechanism which grasps and transports the film section to the stacking point. The gripper is mounted on a circulating or chain which passes around idler rollers to return from the film stacking stage to the film pick up point. Stacking efficiency is increased by using two or more grippers located behind each other in the moving direction. The grippers are independently driven and follow a common path from the film pick up to deposition point. Grippers are operated in a sequence which ensures that while one gripper is transporting and depositing a film section the second gripper is positioned ready to pick up the next film section. USE/ADVANTAGE - The machine transports and stacks sections of film after cutting to length, reduces cycle time and is easily adjusted to the cutter speed.
