Patent DE-4315701-A1 (DE)
Title: Safety valve made of plastic for containers
IPC: F16K24/00
Filed: 1993-05-11
Abstract: The safety valve (1), designed as an aeration and venting valve, for tanks, drums, pallet containers and similar containers made of plastic for transporting and for storing liquids consists of a valve stopper (2) for closing the aeration and venting bung (6) or the filling and emptying bung of a container (5), a membrane (3) and a clamping ring (4). The components (2-4) of the valve (1) are produced as plastic injection-moulded parts. The valve stopper (2) has a central aeration channel (8) which is coaxial with the stopper axis (7-7) and a venting channel (9) which is arranged concentrically to said aeration channel and is designed as an annular channel. The aeration channel (8) and the venting channel (9) open out into aeration and venting apertures (10) in the upper section of the valve stopper (2). The disc-shaped membrane (3) is fitted with a central flap (11) for opening the aeration channel (8) when there is low pressure in the container and with an outer annular section (12) for opening the venting channel (9) when there is overpressure in the container. By means of the clamping ring (4), which is clipped onto the valve stopper (2), the membrane (3) of the valve (1) is held under prestress on a valve seat (13) at the outlet end (14) of the aeration channel (8) in the valve stopper (2). The clamping ring (4) has an aeration aperture (15) which is coaxial with the aeration channel (8) in the valve stopper (2) and an annular venting aperture (16) which is coaxial with the venting channel (9) in the stopper (2). <IMAGE>

Title: Threading guide for constant speed wind up - has swing arm to change direction of entrainment into direction of tube rotation to reduce tension fluctuations
Inventor: STITZ ALBERT
IPC: B65H54/34
Filed: 1993-05-18
Abstract: A constant velocity yarn winder has a grooved traverse roller and a surface drive roller. It uses yarn tubes with entrainment slots in a plane outside the traverse range and has guides to form a yarn reserve. When threading up with an air gun a threading guide swings from a position on the side near the surface drive roller and away from the traverse roller to a position away from the surface drive roller and pref. near the traverse roller. USE/ADVANTAGE - The winder changes the direction of entrainment of a running threadline from being against the direction of rotation to being in the same direction, without requiring major constructional changes. This avoids tension fluctuations esp. if the yarn is being delivered by constant speed godet rollers.

Title: DRAM with self-refresh function - has respective oscillator circuits for generating clock signal for defining refresh cycle in normal and test modes
Inventor: TANIZAKI TETSUSHI
IPC: G11C11/406
Filed: 1993-05-28
Abstract: The memory includes cells arranged in lines and columns. The refresh address signal is provided by a refresh address generator (14), on application of a clock pulse signal. The refresh address signal triggers a device for marking a cell to be refreshed. The clock pulse signal is generated by an oscillator circuit (13). The first clock pulse signal has a frequency defining a refresh cycle in a normal self-refresh mode. A second oscillator circuit (16) generates a second clock pulse signal with a higher frequency. A selective applicator (17, 18) responds to an external test mode signal to apply the first or the second clock pulse signal, to the refresh address generator. ADVANTAGE - Increased speed for self-refresh function and verification.

Patent DE-4320141-A1 (DE)
Title: Four-ply composite film of a paper/silicone/plastic/metal structure
Inventor: HEISTER MATTHIAS DR
IPC: C09J7/28
Filed: 1993-06-17
Abstract: The invention relates to a four-ply composite film of a paper/silicone/hot-melt adhesive/metal, preferably aluminium, structure. The metal foil may have a special colour finish, for example be anodised. The UV-resistant hot-melt adhesive, preferably copolyamide, is adjusted such that it firmly bonds the metal foil to the underlying surface upon heating and such that, in the cold state, the metal foil can be removed again along with the hot-melt adhesive layer totally without leaving any residual material from the underlying surface. According to the invention, the adhesion of the hot-melt adhesive on the metal and the adhesion of the silicone on the paper are stronger than the adhesion of the hot-melt adhesive on the silicone layer. As a result, the hot-melt adhesive/metal foil, which is reinforced by the hot-melt adhesive, can be easily peeled off the paper/silicone film for the purpose of using as a covering (masking), for example of glass surfaces and other surfaces. The procedure adopted for producing the four-ply composite film is that first of all the hot-melt adhesive layer is applied in a cold low-viscosity state to the silicone side of the paper/silicone film, subsequently the metal foil is laminated onto the hot-melt adhesive side and, in the case of perforation, the entire four-ply composite film is punched, preferably hole-punched. <IMAGE>
Patent DE-4323480-A1 (DE)
Inventor: ENSINGER WILFRIED
IPC: C23C28/00
Filed: 1993-07-14
Abstract: A process for coating composite profiles with powder lacquers, comprising two profile parts of metal and at least one insulator of plastic, interconnecting these profile parts while at the same time forming a heat bridge, comprises the electrostatic application of a lacquer powder to the outer sides of the composite profile and the subsequent sintering together of this powder under the effect of heat to form a lacquer coating. The outer sides of the plastic insulators to be coated have applied to them beforehand a thin, electrically conductive coating which, during sintering of the lacquer powder, improves the adherence of the latter on the insulator. An insulator produced by this process has on its one outer side a thin, electrically conductive coating which, during sintering of the lacquer powder, improves the adherence of the latter on the insulator. <IMAGE>

Title: Thick walled, quality, co-extruded plastic sections from waste; with
Inventor: SACHSE LOTHAR
IPC: B29B17/02
Filed: 1994-03-23
Abstract: The profiled co-extrusions, as sections, sheets or tubes, are made from a feedstock of mixed and soiled plastic waste with minimal energy expenditure. Coarse sorting classifies the sheet, hollow-ware and canisters, separating the refuse and foreign matter. The object is to recover the plastic fractions, which are shredded into staple lengths. They are then surfused, i.e. surface heated and melted; pressed into bales, which are strapped-up as pallets. Efficient transport in this form to the special extruder and co-extruder plant follows; there, the plastic is co-extruded with a controlled wall thickness; no further preparation is required.
