Title: Germ-free ventilating apparatus above refrigerated counters, food storage tables, buffets and the like
Inventor: HOELTER HEINZ DIPL ING
IPC: A47F3/04
Filed: 1988-12-08
Abstract: The invention relates to a device for the bacteria-free storage of foodstuffs, etc. on refrigerated counters, etc. accessible from all sides, having a roof-like reinforcement (1), from the edges of which a stabilising air curtain (2, 3) is directed towards the refrigerated counter, etc. and from the inner sections, bounded by the edges, of which a slow, laminar air flow (4) is directed at the refrigerated counter. The object of the invention is to further develop the abovementioned device for the bacteria-free storage of foodstuffs and the like on refrigerated counters and the like which are accessible from all sides, in such a way that even bacteria originating from the products or bacteria which have penetrated the air curtains owing to temporary interruption thereof can be eliminated, and that drying-out of the products situated on the refrigerated counter is reliably avoided. According to the invention, this object is achieved in that bactericidal and fungicidal chemisorption filters are arranged in the roof-like reinforcement (1), it being possible for these filters to be injected with moisture corresponding to a desired air humidity. <IMAGE>

Title: Process for the production of mouldings, boards or slabs of rigid polyurethane foam
Inventor: SCHAPER HERBERT DIPL CHEM DR
IPC: C08J9/14
Filed: 1989-01-31
Abstract: The invention relates to a process for the production of mouldings, boards or slabs of rigid polyurethane foam (for example insulating material, refrigerator insulation, building protection boards, rear spoilers) having a density of 0.01 to 0.8 g/cm<3>, by foaming the polyol component (component A) with the isocyanate component (component B) in the presence of a blowing agent (component C).

Title: Pipe-securing means
Inventor: SEBERT KARL DIPL ING
IPC: F16L55/035
Filed: 1989-03-04
Abstract: The invention proposes a pipe-securing means for the elastic fixing of pipes (12), a securing element (31), in particular a pipe clamp, receiving an elastic insert part (30) which engages around the pipe (12). The insert part (30), designed as an essentially dimensionally stable block in one or two pieces, exhibits a through-passage opening (11) which receives, in clamping fashion, the pipe (12) which is to be fixed, that region of the insert part (30) which encloses the through-passage opening (11) comprising integrally formed abutment elements (32) which run in the axial direction and have a considerably smaller abutment or cross-sectional surface area than the circumferential surface area of the enclosed pipe (12). By virtue of the small cross-sectional surface area, sound and vibrations can be transmitted only to a slight extent to the pipe clamp and/or to the fastening surface area, and structure-borne-sound vibrations are damped very strongly as a result of the good insulation. <IMAGE>

Patent DE-3921096-A1 (DE)
Inventor: NEUHAUS KLAUS
IPC: H01F38/42
Filed: 1989-06-28
Abstract: In known diode split transformers, transient effects occur during the forward line trace which impair the image quality. In the novel diode split transformer, no transient effects impairing the image quality should occur. Essentially, this is achieved by the fact that a diode (D4) is connected in parallel with the part-winding (I1) of the diode split transformer which is closest to earth, in such a manner that interference oscillations occurring at the part winding closest to earth during the forward line trace are bypassed to earth. <IMAGE>
