Abstract: ABSTRACT OF THE DISCLOSURE         A method for producing non-shrinkable glue or coating film from hot melt is described.  The glue or coating film is to be deposited on the surface to be glued or coated or between the different surfaces, and it is made adherent thereto by fusion.   The glue or coating film is produced by applying hot melt with the aid of a recessed roll onto a peel-off paper web, from which the perforated, reticular film can be peeled off to become separate glue or joining film, either immediately or subsequently in con-nection with the gluing or coating operation.  The reticular structure of the gluing or coating film is regulated by changing the recess pattern of the recessed roll.

Abstract: ABSTRACT       The method and apparatus for generating seismic vibrations in a liquid includes an electronically controlled, hydraulically powered generator that includes a piston assembly reciprocally mounted on a cylindrical post in a generator housing.  The control apparatus includes a control valve that is located very close to the piston assembly thereby reducing the volume of the passageways extending to the piston assembly so that the cyclic rate of the piston assembly can be very rapid and can be changed accurately and quickly.  An extended life is provided by releasing the high pressure fluid driving the piston assembly prior to impact between the piston assembly and the post and by providing a trapped volume of fluid in the chamber to damp the movement of the piston assembly toward the post.

Abstract: BEHIND CASING WATER FLOW                          ABSTRACT (D#77,831-F) A method for providing a signal representative of undesired water flow behind well casing in a producing well includes locating a well tool sized and adapted for passage through a well bore having a source of high energy neutrons at least some of which have sufficient energy to cause a nuclear reaction O16 (n,p) N16 and at least three (3) gamma ray detectors spatially arranged in a predetermined manner with said source and each other in a well bore at a depth to be investigated.  The environs of the bore hole are irradiated with high energy neutrons from said source.  The gamma ray detectors detect gamma rays resulting from the decay of the unstable isotope N16 comprising a portion of any undesired behind casing water flow present.  Count signals representative of the detection are generated.  The count signals are combined according to a first predetermined relationship to derive at least two net count signals for two of the three detectors.  The net count signals are combined according to a second predetermined relationship to derive the signal representative of the linear flow of the undesired water flow behind the well casing.

Abstract: DISPLAY FORMS USING LIQUID CRYSTALS            ABSTRACT In a display device, planar or curved, panel or coloured pane it is known that the image or the colours do not change noticeably with the angle of viewing or angle of illumination.  In this invention drastic changes in the image and colours can be obtained using cholesteric or other chiral liquid crystal coatings or polymers with liquid crystaline properties.  In addition the colours are more intense than feasible with other colourants.  These two properties are value in applications where it is desired to attract the viewers attention such as in advertising and signage.  In a coloured pane consisting of ornamental or stained glass parts it is known that the process of achieving the desired image effects is not simple and limited in scope.  Using liquid crystal coatings the process of achieving such effects is greatly simplified and less expensive.  By providing two or more liquid crystal coatings on transparent substrates overlaying each other new colours and three-dimensional effects can be obtained as a result of the colour additive properties of liquid crystals coatings which do not absorb light.

Abstract: ABSTRACT OF THE DISCLOSURE           A process and device are disclosed for applying a free-flowing material to the inner surface of a tube blank.   The material is applied to the inner surface by means of a carrier gas stream, provided with a swirl, conducted through the hollow space.  To prevent or reduce swirl loss, which occurs if the laden carrier gas stream, provided with the swirl, forces stagnant air in the hollow space from this space and then the loss develops by friction on the inner surface, before and during the flow of the laden carrier gas provided with the swirl, an additional gas, not laden with the material, is conducted through the hollow space with a swirl, having a direction of rotation which corresponds to the swirl of the laden carrier gas stream.   For this purpose,  the device is provided on the outlet of a passage element equipped with a swirl-producing device for the laden carrier gas stream, with outlet nozzles which feed to the laden carrier gas stream the additional gas with a swirl, having a direction of rotation corresponding to that of the swirl-producing device.

Abstract: TITLE          End Pivot Webguide ABSTRACT OF THE DISCLOSURE    An end pivot webguide which may be economically fabricated from stock material and eliminating many cast components is disclosed including pivot arms formed from bar stock and roller frames formed from angle stock.  The pivot arms are formed by drilling passages including annular shoulders for receiving radial ball bearings in the bar stock for rotatably mounting first and second pivot pins.  The use of radial ball bearings allows the pivot pins to accept thrust forces in an axial direction such that the webguide of the present invention utilizes four bearings of identical type rather than six bearings of three different types as in prior webguides.  The pivot arm is symetrical such that one of the pivot pins may be nonrotatably secured to the webguide base and the other pivot pin may be nonrotatably secured to the roller frame.  Bearings in the guide rolls rotatably mount the guide rolls on screws removably and nonrotatably secured to the roller frames.  Different sized guide rolls may then be utilized by simply selecting corresponding sized angle stock forming the roller frames.

Abstract: Method for making of feed blends containing materials which need to be ground up. A production line for grinding and weighing of material contains several silos or storages 1 with dispensing systems 2. By means of a distributing layout 3, the materials which are not to be ground are taken directly to the scale 4. Materials which need to be ground are taken to the scale via the desired mill type 5, 6, so that the grinding occurs at the same time as the weighing. The dispensing systems thus are controlled by both the mill workload and the weight. In order to make better utilisation of the mills, the ingredients of the feed blend can be advantageously weighed on several parallel production lines, with or without mills. With this method, a very simple and quick production process is achieved, which is easy to control, and where it is possible to give the individual ingredients an optimal structure. The compact layout without intermediate containers and elevators saves energy and at the same time makes it easy to keep the plant clean, so as to prevent the formation of salmonella bacteria, for example. <IMAGE>
