Filed: 1980-02-13
Abstract: Method for quantitative analysis of free fatty acids (FFA) comprises first reacting them with acyl-coenzyme A synthetase (I) in presence of ATP and coenzyme A to produce acyl-coenzyme A (II). This is reacted with microbial acyl-coenzyme A oxidase (III) in presence of O2 and (a) either the amt. of H2O2 or of enoyl-coenzyme A (IV) produced or (b) the amt. of O2 consumed, measured. Esp. H2O2 is measured (a) as aldehyde after reaction with alcohol and catalase or (b) as dye formed by oxidn. of a chromogenic H donor in presence of peroxidase. (III) is esp. derived from Candida lipolytica. Reagent consisting of (I), (III), coenzyme A and ATP is also claimed. The method measures H2O2 directly, has excellent reproducibility and is easy to carry out. The microbial (III) used gives practically 100% reaction with FFA compared with only 60% for the conventional rat-liver enzyme.

Title: Co-extrusion of composite thermoplastic sheet for biaxial stretching - with uncoated edge strips in regions of stretching clamps
Inventor: DINTER PETER
IPC: B29C48/49
Filed: 1980-03-20
Abstract: Prodn. of a co-extruded composite sheet comprising at least two thermoplastics, using an adaptor in which the plasticised materials are brought together to form a multi-layer column which is then expelled through a fish tail die, is intended for subsequent biaxial stretching of the composite sheet. Individual extruded columns of the different materials of rectangular or aquare section are combined in the adaptor in such a way that the lateral edges of the column subsequently to be flattened into a sheet are covered with upright layers of the same material as the central region or of a different material. Thus the resultant product is a "sandwich" where the edges of the sandwich are coated with vertical layers. Process is used in the prodn. of multi-layer, typically two-layer or three-layer composite sheet. In the subsequent biaxial stretching the edges of the sheet are gripped by clamps and are subsequently cut away as waste material By forming these edges of cover strips the expensive facing materials of the sandwich composite sheet are kept away from the edges and therefore do not form part of the waste. Not only does this save expense but the edge material is more easily recycled into the relevant extruder.

Title: Film scanning system for TV display - has prom stores for selected film format to read-out output from transducer of film scanned line-by-line without interlacing
Inventor: MASSMANN VOLKER DIPL ING
IPC: H04N3/38
Filed: 1980-03-29
Abstract: The system for the television scanning of films comprises a frame store into which respective signals belonging to a scanned line are read at an address characterising the position of the line within the film frame and from which are read out once again in accordance with the television standard. In so doing, the respective address is formed either by counting pulses derived from the line and frame frequency of the television standard (coupled operation) or by counting pulses derived from the film speed (uncoupled operation). To prevent cut edges with studio asynchronous film speeds below 50 frames per second, during the reading in of one film frame into one half frame store, the other half frame store is simultaneously completely and frequently read out until the reading in of the one film frame has finished.

Patent DE-3104726-A1 (DE)
Title: Packaging container for viscous and pasty contents
Inventor: AMS ANDREAS
IPC: B65D83/00
Filed: 1981-02-11
Abstract: The invention relates to a packaging container for viscous and pasty contents, in particular toothpaste, having a cylindrical hollow body and a device for the apportioned delivery of the contents, consisting of a top part which terminates the hollow body on one side and has a delivery aperture, a plunger which is axially displaceable in the hollow body and bounds the filling space, a rod which passes centrally through the plunger and is axially displaceable outside the container counter to the resistance of a returning spring, and a blocking device which acts on one side. A packaging container of this type is known from German Patent Specification 678,288. However, in practice it has not proved its worth, especially since the device for the apportioned delivery of the contents has to be operated from the bottom or standing surface of the container. For a container of this type, it is therefore proposed that the blocking device consists of a component (3) which acts only between the plunger (1) and the rod (2), and that the rod (2) is axially displaceable by means of an operating device (5) arranged in the top part (4).

Patent DE-3116078-A1 (DE)
Inventor: BAUSER HERBERT DIPL PHYS
IPC: B44C1/16
Filed: 1981-04-22
Abstract: A stamping foil for forming printed circuit patterns on insulating or poorly conductive substrates comprising an electrically conductive layer made of a highly conductive metal, such as copper, which is endowed with a sufficiently low shear strength, even in thicknesses of 10 microns or more, to permit easy and sharp separation of the activated (imprinted) and non-activated portions of the foil. Such a low shear strength may be achieved with fibrous or fibrous-granular crystallite structures, wherein the fibers are oriented approximately at right angles to the surfaces of the foil, and, in addition, by doping agents containing carbon, nitrogen and sulfur. The foil may comprise a bonding layer for bonding the conductive layer to a substrate, or such a bonding layer may be applied to the surface of the conductive layer before the stamping operation. The conductive layer may be either self-supporting, or it may adhere to a carrier tape through an intermediary separating layer. In the latter case, the bonding and separating layers become activated when compressed by a stamping die or stereotype, whereby the conductive layer becomes bonded to the substrate and separated from the carrier tape in the activated areas. The activated and non-activated portions of the foil are then separable by pulling the carrier tape away from the substrate.

Title: Method and device for controlling a pneumatically operated servomotor
Inventor: BAUMGARTNER HANS DIPL ING
IPC: F15B11/06
Filed: 1981-07-18
Abstract: In method of controlling a pneumatically operated servomotor by means of at least one electrically actuated valve:   a) a control pressure is produced by means of the valve in a primary space of relatively small volume, and b) by means of a diaphragm acting between the primary space and a servomotor working space of relatively large volume, a double seat valve loaded with the pneumatic working pressures is actuated until a pressure balance prevails between primary space and working space.   A device for carrying out this method has:   a) a primary space essentially enclosed by a diaphragm and a housing lid and at least one feed line for pneumatic control pressure, b) a servomotor working space in gas-pressure connection with the diaphragm, and c) a double seat valve loaded on the one side with the pressure in the working space and on the other side with the pneumatic working pressures and actuated by the diaphragm.
Patent DE-3132720-A1 (DE)
Title: Cleaning of hollow fibres
Inventor: SIGDELL JAN-ERIK DR
IPC: C11D7/50
Filed: 1981-08-19
Abstract: The invention relates to a method for cleaning hollow fibres for dialysers and other blood-treatment apparatus of similar construction using a mixture of a liquid which does not take up water with a liquid which does take up water, because experiments show that in this way the advantages, but not the disadvantages, of the two liquids (as shown on use of the corresponding components alone) are combined. In the manufacture of a dialyser or the like from hollow fibres, the latter are first washed out in order to remove an oily liquid present therein, and subsequently moisture is removed in a special drying process in order to reduce the water content of the fibre material. The use of a liquid which takes up water for washing has the disadvantage that the fibres shrink, and thus lose permeability, but also the advantage that part of the moisture is removed during the washing. The use of a liquid which does not take up water eliminates shrinkage but also the uptake of moisture. Experiments show that the advantages of the two are combined, without the disadvantages, (moisture uptake without shrinkage) by a mixture.
