Patent DE-3720007-A1 (DE)
Inventor: SACHSE HELMUT
IPC: B65D5/16
Filed: 1987-06-15
Abstract: The dispenser box has four peripheral walls (4, 6, 8, 10), a bottom and a lid, it being possible for a removal flap (24) with two lateral boundary tabs (28, 30) of the opening to be swivelled out of the front peripheral wall (4). The boundary tabs (28, 30) of the opening are constructed integrally with a material strip (38) which is bonded to the inside of the removal flap (24). Said material strip is preferably made integrally with the bottom tab (72), which is attached to the front peripheral wall (4), of the bottom, which is constructed as a foldable bonded bottom, and is connected to said bottom tab via a tear-off edge (78). The material strip (38) is then folded, together with the bottom tab (72), in an automatic folding stage onto the inside of the blank and bonded in its position. When the dispenser box is set up from the flat-folded state into the box shape, the bottom tab (72) lifts up from the peripheral wall (4), thus tearing off the tear-off edge (78). <IMAGE>

Title: Use of a special propene polymer in the production of heat-sealable films
Inventor: SCHOENE WERNER DR
IPC: B32B7/027
Filed: 1987-09-30
Abstract: The framework of the invention is the production of heat-sealable films consisting of (i) a basic film of polypropene (polypropylene) and (ii) a heat-sealable layer which is applied to the basic film and comprises a propene polymer with a relatively low softening point. The characteristic feature is that the propene polymers used for the heat-sealable layer are those obtained by continuous production of random copolymers of propene by polymerisation of a monomer mixture by means of a Ziegler-Natta catalyst system in the gas phase in a centric stirred bed comprising small-particulate polymer with removal of the heat of polymerisation by evaporative cooling, the monomer mixture being introduced constantly into the polymerisation zone and the polymer being constantly discharged from the polymerisation zone, with the provisos that (a) in the polymerisation zone pressure and temperature are kept in a range corresponding to the gaseous state of the monomer mixture, (b) gaseous, unconsumed monomer mixture is discharged from the polymerisation zone and reintroduced into the polymerisation zone in the liquid state, (c) the temperature in the polymerisation zone is controlled by means of the amount of liquid monomer mixture introduced per unit time, and (d) the monomer consumed by polymerisation is replaced, with the special feature that - with the use of a monomer mixture comprising principally propene, a little ethene and very little hydrogen - the residence time of the ...

Title: Process for joining flanges with a smooth sealing strip, and means suitable for carrying out the process
Inventor: TUECKMANTEL HANS-JOACHIM DIPL
IPC: F16L23/00
Filed: 1988-02-13
Abstract: The invention relates to a process for joining flanges with a smooth sealing strip, with the interposition of a flat gasket which terminates with the outer edge of the sealing strip, to form a flange connection. In the case of the process of the generic type, the flat gasket is introduced into a gap formed between the flanges and is aligned with the sealing strip, and a plurality of screws are guided, with compensation play, through bores arranged uniformly on the circumference of the flanges and are combined with nuts to form screw connections. The process according to the invention is characterised in that adjustment bolts are inserted, with a constricted degree of radial play, into at least two offset bores until the gap formed between the flanges is bridged over, in that the flat gaskets are then introduced into the gap and laid on the adjustment bolts, in that the flanges are subsequently braced with respect to one another by at least two screw connections and the adjustment bolts are finally removed and replaced by screw connections. Special adjustment bolts are also specified. <IMAGE>

Title: Metal core printed circuit board
Inventor: ZUROWSKI ROMAN DR ING
IPC: H05K1/05
Filed: 1988-08-27
Abstract: Such a printed circuit board has a metal core (2) which is surrounded by a sheath (3) made of dielectric material. Conventionally, it is produced by a metal core in the form of a plate being coated on both sides with plates made of an insulating material, for example from paper or glass-fibre mats impregnated with synthetic resin. The problem is to produce such printed circuit boards at a reduced labour cost. This problem is solved by the sheathing (3) of the printed circuit board (1) being produced using the injection die-casting technique, and by the metal core (2) being produced as a three-dimensional moulded plate. In consequence it is possible to construct the metal core (2) such that heat losses from components can be dissipated directly via it. In addition, a defined position of the metal core (2) can be ensured during injection die-casting, and a good connection of the sheathing (3) to the metal core (2). <IMAGE>

Title: Wing construction for energy transmission in the media of water and gas, and for a vehicle for movement on land or water and in the air
IPC: B63B1/24
Filed: 1988-10-15
Abstract: An improved performance, stability, noise reduction, energy saving, safety and vibration reduction as well as utilisation of the wing or propeller etc. is achieved in that the design of each wing in production is based on a principle which consists of three design features being used which are three-dimensionally connected such that they communicate, and three-dimensional lift being produced in operation. A further improvement results from the fact that the high air pressure around the stagnation point is used in operation to influence the incident flow line profiles effectively and favourably and to make it possible to control aircraft without control surfaces.
Patent DE-3835931-A1 (DE)
Title: Push-button switch
Inventor: RIEGER HELMUT
IPC: H01H13/56
Filed: 1988-10-21
Abstract: In the case of a push-button switch whose locking pin interacts with a locking profile on a latching rail which can be displaced laterally, the latching rail is mounted such that it moves in the third dimension, that is to say vertically downwards, so that the latching rail can be disengaged from the latching pin or latching pins. In consequence, the push-button switch can be moved into the switched-off position when the pivoting lever, which supports the latching rail, is not acted on by an actuating element, for example a housing door. In this way, the push-button switch allows a safety function to be carried out without any additional door switches, positive disconnection of the apparatus being achieved and self-latching switching-on being prevented.
