Title: Use of a specific propene polymer for the production of films
Inventor: SCHOENE WERNER DR
IPC: C08F2/34
Filed: 1987-09-30
Abstract: The invention relates to the production of films from propene polymers, characterised in that propene polymers are employed which are obtained by continuous preparation of random copolymers of propene by polymerization of a monomer mixture by means of a Ziegel-Natta catalyst system in the gas phase in a central stirred bed of finely divided polymer with dissipation of the heat of polymerization by evaporative cooling, where the monomer mixture is constantly introduced into the polymerization zone and the polymer is constantly discharged from the polymerization zone, with the provisos that (a) the pressure and temperature in the polymerization zone are kept in a range which corresponds to the gaseous state of the monomer mixture, (b) gaseous, unconsumed monomer mixture is discharged from the polymerization zone and is re-introduced into the polymerization zone in liquid form, (c) the temperature in the polymerization zone is regulated by means of the amount of liquid monomer mixture introduced per time unit, and (d) the monomers consumed by polymerization are replaced, with the particular feature that - using a monomer mixture comprising principally propene, a little ethylene and very little hydrogen - the residence time of the monomer mixture in the polymerization zone is kept very short.

Title: Method of generating coloured images on a carrier surface
Inventor: GALL WINRICH DIPL ING
IPC: G03F3/08
Filed: 1987-11-09
Abstract: A method of generating coloured images point-by-point, using devices which in generating the individual image points permit only a few different options in relation to colour components and size, is described. The image point which is generated is the one which causes the smallest difference between the required and generated colour stimulus specification vectors. This difference vector is taken into account when generating subsequent image points. A modification of this method, which is necessary if the individual image points overlap, is also described. <IMAGE>

Title: Process and apparatus for producing mouldings from fibrous moulded material and a moulding produced by this process
Inventor: DOEHLER JOCHEN
IPC: B29C70/46
Filed: 1987-11-18
Abstract: Mouldings are produced from a mat or web of a fibrous moulded material which is provided with a binder and with an inlay or overlay, increasing the tensile strength, by hot pressing in correspondingly contoured moulds. For forming strips, straps or the like which are arranged at a distance from the edge and at an angle to the surface of the moulding, the mat or web is prepared on the side having the strip or strap with an overhang. The pressing causes the said overhang to be delimited from the actual moulding by a bending line, which is formed along the edge of the moulding, and to be formed into an angle profile. The angle profile is then folded around the bending line until its one leg comes to bear against the surface of the moulding and the said leg is bonded to the moulding, while the other leg forms the strip or strap.

Inventor: WOHLLEBEN WOLFGANG DR
IPC: C12N15/10
Filed: 1988-03-23
Abstract: DNA segments from mutants can be obtained very straightforwardly by isolating from the strain to be mutated the total DNA, cleaving the latter into small fragments and integrating into a temperature- sensitive plasmid with another selection marker which is selectable in E. coli, transforming the hybrid plasmid population obtained in this way into the starting strain, selecting the transformants by selection for the marker, eliminating the hybrid plasmids by raising the temperature above the threshold of the temperature-sensitive plasmid, and selecting the mutants by renewed selection for the marker. Construction of a cosmid gene bank with the DNA of these mutants results, by selection for the marker which has been introduced and is selectable in E. coli and for the cosmid-intrinsic marker, directly in cosmids which contain the mutated gene.

Patent DE-3823187-A1 (DE)
Inventor: RICHTER ERWIN
IPC: E05F15/643
Filed: 1988-07-08
Abstract: The invention relates to an automatic door or window installation with at least one driven sliding wing. It serves as a replacement installation for exchanging a corresponding old installation to be replaced in a carrier structure anchored in place. To exchange an old installation of this type, work involving a high outlay is necessary at the present time, so that the new drive can be inserted into the carrier structure installed in place. The invention makes a simple and cost-effective conversion possible, in that the replacement installation is fastened in the slide rail of the old installation. This means that, for the conversion, the old installation is firstly removed from the fixed carrier structure, the carrier structure 6 together with the slide rail 27 of the old installation remaining installed in place. The replacement installation is then fastened to the slide rail 27, especially by hooking and clamping by the use of a separate coupling adaptor 20 which has a fastening profile 31 engaging into the slide rail 27. <IMAGE>

Title: Lamp-cleaning system for motor vehicles
Inventor: BOIS WILHELM DIPL ING
IPC: B60S1/60
Filed: 1988-07-25
Abstract: A lamp-cleaning system for motor vehicles is described, in particular headlamp cleaning system which can be put into operation by means of switching means directly by switching on the lamps and/or when they are operated by switching on a windscreen cleaning system. For the purpose of reducing the cleaning agent consumption, a brightness sensor is provided as further marginal condition on which the operation of the lamp cleaning system depends, so that the time of day can be taken into account when controlling the lamp cleaning system. This measure is based on the recognition that, above all, the lamp cleaning system is to improve the view of the driver when driving at night, but is not intended for a better illumination of the vehicle during daytime so that it may be better recognised by other participants in traffic. The essential advantage is therefore that in particular during daytime the consumption in terms of cleaning agent can be reduced to a large extent.
Patent DE-3827399-A1 (DE)
Title: Bracket for mounting the rack-bar sections serving to move a shearer loader
Inventor: KLIMECK HUGO
IPC: E21C29/02
Filed: 1988-08-12
Abstract: Rack-bar sections engage with a bottom extension in pairs in one bracket each and are connected to the bracket by bolts running transversely to the longitudinal direction of the rack bar. The bolts pass through a bore in the rack-bar extension and lie with their ends in bores in the bracket side walls. They are held in the axial direction by one clamping pin each, which also secures the bolts against rotary movements. Clamping-pin deformations and damage, which can be noticed in underground use, under the operational load of the shearer loader moving along the rack give cause for complaint. It is therefore proposed to provide the top area of the face-side bracket wall (12) with reinforcement (15) on its outside. The reinforcement (15) partly closes the outer ends of the two bores (10, 11) in this wall (12). On the other hand, the goaf-side bracket wall (13) has on its outside a recess (16) into which both bores (10, 11) lead. This recess (16) extends over the entire height or over the entire length of the goaf-side bracket wall (13) and can be occupied by a locking plate (17, 18) at least partly covering both bores (10, 11). <IMAGE>

Patent DE-3917756-A1 (DE)
Title: Set of structural elements for a ballast basket
Inventor: LOOSLI MANFRED
IPC: E02D29/02
Filed: 1989-05-31
Abstract: The set of structural elements is obtained in that the wires are arranged in an equidistant manner and are located one upon the other orthogonally. The wires are welded at the points of intersection. The grid panels (1) formed in this manner then have a unit-dimension bay which, when a whole number of said bays are lined up one beside the other, fixes the length and width of the grid panels (1). Partition walls can thus be introduced into ballast baskets. The grid panels do not have to be aligned at right angles with respect to one another or connected to one another at the borders. Stable walls can thus be formed, it being possible for the grid baskets to be offset with respect to one another by whole-numbered multiples of the unit-dimension bays. The grid panels (1) are connected by spiral wires (2) which, correspondingly, have a uniform pitch and can be inserted at any location. <IMAGE>
