Patent DE-4022891-A1 (DE)
Title: Patterned needled nonwoven material prepn. - by forming needled material into velour web and overlaying layer(s) of textile fibres
Inventor: DILO JOHANN PHILIPP
IPC: D04H11/08
Filed: 1990-07-18
Abstract: To produce patterned needled non-woven materials, a single or multi-layer needled material is formed into a velour web using crown and/or fork needles. At least one layer of textile fibres is overlaid to give at least one pattern, esp. using staple fibres, using fibres which are different from the carrier web in terms of colour and/or shape and/or material and/or thickness and/or orientation, wholly or partially over the surface. The combined material is further neddle bonded, so that the fibres on one side are passed through to be visible on the other side, to form piles generally on the under side of the web. - Pref. the preneedled non woven is of randomly laid fibres, or of oriented fibres aling the web length or laterally. The patterning fibre layer is laid wholly over the carrier web, or as one or more strips, or a number of shaped fibre sections, and the patterning fibres are oriented across the fibres in the carrier we. Staple fibres can be delievred to the carrier weby by a continuous or intermittent air stream, through a mouthpiece extending wholly or partially across the carrier web width, and a number of mouthpieces can be used to deliver fibre-charged air streams.

Patent DE-4032173-A1 (DE)
Title: Method of applying paint or lacquer to flat workpieces
Inventor: BARBERAN ALBIAC JESUS
IPC: B05C1/08
Filed: 1990-10-10
Abstract: The process consists of allowing a textile piece of suitable shape and characteristics, impregnated with a hardening synthetic resin, to set over a 3-dimensional matrix shaped like the required article. The material passes through an intermediate stage of setting which allows shaping and retention of the given shape. When hardening is complete, the matrix is removed and the fabric retains its shape, giving the impression of being suspeneded without gravity in air, and with marked translucency if transparent resin and fine white fabric are usedo

Patent DE-4092411-A1 (DE)
IPC: A21D8/04
Filed: 1990-12-15
Abstract: Cereal flour products are mixed with water and a pitching substance containing microorganisms to form a leaven starter. During the subsequent maturation, the leaven starter undergoes a fermentation process in which, after a lag phase, it passes into an exponential growth phase. To obtain an improved leaven product, a buffering or basic substance is added during the exponential growth phase in order to increase the concentration of revitalizable microorganisms. Measures (cooling or drying) are adopted during the exponential growth phase of the microorganisms with a view to making the product storable.

Patent DE-4108460-A1 (DE)
Inventor: NEUMANN ERICH
IPC: G05D23/19
Filed: 1991-03-13
Abstract: When process parameters such as temperature are monitored, abrupt changes are not promptly detected because of delays due to the measurement apparatus and the processing of the measured values. The measured value of a suitable parameter is therefore sampled at at least one measurement point at small equal time intervals and compared with the preceding measured value. Any difference between the two measured values, which indicates an unallowable, in particular abrupt, change in the value of the parameter, activates a process-regulating mechanism before the unallowable value itself is derived from the measured value and indicated. The transition functions of the measurement transducers must be determined at the individual measurement points and reference valued corresponding to the running of the process established. The preferred application is for monitoring temperature in a long, flow-conducting tubular reactor in the production of LDPE and controlling the process by varying the pressure and/or the quantity of the oxygen carrier added. The invention can also be applied in other reactors, such as container-shaped reactors.

Patent DE-4120387-A1 (DE)
Inventor: HOVELING STEFAN
IPC: C23C4/02
Filed: 1991-06-20
Abstract: For a wide variety of applications, in particular in the building sector, there is a demand for decorative surfaces which have a colouring which can be individually adjusted and is independent of weathering or treatment with chemical solutions. The method of producing a structured surface according to the invention, preferably on rolled copper strips, provides first of all a mechanical treatment, by which the surface is selectively roughened. In a further method step, the roughened surface then receives a coating, applied by thermal spraying with metal-powder particles. Powder particles of aluminium, copper, nickel and tin as well as powder particles of alloys of these materials, for example of a copper-tin alloy, are suitable as the spray-powder material.
