Abstract: HIGH DENSITY CAPACITIVE TOUCH   SWITCH ARRAY ARRANGEMENT                          ABSTRACT OF THE DISCLOSURE   A capacitive touch switch arrangement which alleviates panel layout problems which result from the minimum area required for proper operation of capacitive touch switches.  There is at least a pair of capacitive touch switches, each having, as its input element, a touch pad of sufficient area for proper operation of the touch switch. A pair of primary touch sensitive areas are delineated, such as by panel indicia, and arranged such that a touch on either primary touch sensitive area activates only one of the touch switches.  In addition, at least one secondary touch sensitive area is delineated and arranged such that a touch on the secondary touch sensitive area activates both of the touch switches.  A circuit means responsive to the touch switches includes decoding logic for generating different outputs in response to the touching of each of the touch sensitive areas.  Thus, there is not a one-for-one correspondence between all of the touch sensitive areas and the touch pads. In particular, there are more delineated touch sensitive areas than touch pads, and the touch sensitive areas may be smaller in area than the touch pads.

Abstract: ROTARY FILM STRIP HOLDING APPARATUS       Abstract of the Disclosure Apparatus for holding film strips of the type having a plurality of miniaturized film images car-ried thereon, wherein the apparatus is to be used with an optical system which illuminates and pro-jects the images on an enlarged scale so that they can be viewed on a projection screen.  The appara-tus includes a rotary film holder or cassette having a number of concentric cylindrical segments defining a pair of coaxial cylinders, the segments being pro-vided with grooves to permit insertion of a plurality of film strips in the cassette.  The inner segments are longer than the outer segments so that portions of the radially outermost edges of the film strips are exposed and the outer edge of a selected film strip can be engaged by an edge drive wheel to per-mit the selected film strip to be moved partially out of and to be returned to the cassette.  The cassette is rotatably mounted by spaced bearings on a projection carried by a stationary support, and a drive wheel coupled to a reversible motor engages the outer periphery of the cassette to rotate it in opposed directions.  An optical system on the sup-port is used with an X-Y drive to project an image on the selected film strip onto a screen when the film strip is releasably held in a predetermined focal plane by hold-down means. Control structure coupled with the drive motors of the cassette, the edge drive wheel and the X-Y drive controls such motors to effect operation of the apparatus.

Abstract: Abstract of the Disclosure. The method is of the kind whereby a number of strips of packing ma-terial is conducted through a cross section shaping station, through a filling station at which articles are arranged on the strips, through a longitudinally extending welding station at which each strip of ma-terial is welded into tube form, through a cross welding station wherein cross welding seams are made between the articles arranged in the packing tubes, and through a separation station for separating the finished packings from the strips of material. In order to obtain regi-stration of the cross welding seams with respect to a pre-printed pat-tern on the strips of material, the cross welding means are individually controlled as regards their disengagement from the strips of material by means of pulses issued by indication marks arranged along the strips of material and arranged with a pitch corresponding to the length of the packings to be produced. The invention also relates to an apparatus for carrying out the method. (Fig. 4 of the drawing is regarded as being appropriate for being published together with the Abstract).

The devices are formed in single crystalline tubs (11) in a polycrystalline substrate (10).  In order to prevent the potential of the substrate from causing breakdown of the devices, there is included between the single crystalline tubs and the polycrystalline substrate a semi-insulating layer (13) which has trapping states capable of taking on charge from the single crystalline region.  The shielding provided by the semi-insulating layer permits the surface regions of the device to be made closer to the polycrystalline substrate and the tubs to be made more shallow.

Abstract: HEMISPHERICAL LAUE CAMERA                  ABSTRACT     A hemispherical Laue camera comprises a crystal sample mount for positioning a sample to be analyzed at the center of sphere of a hemispherical, X-radiation sensitive film cassette, a collimator, a stationary or rotating sample mount and a set of standard spherical projection spheres.  X-radiation generated from an external source is directed through the collimator to impinge onto the single crystal sam-ple on the stationary mount.  The diffracted beam is recorded on the hemispherical X-radiation sensitive film mounted inside the hemispherical film cassette in either transmission or back-reflection geometry.  The distances travelled by X-radiation diffracted from the crystal to the hemispherical film are the same for all crystal planes which satisfy Bragg's Law.  The recorded diffraction spots or Laue spots on the film thereby preserve both the symmetry information of the crystal structure and the relative intensities which are directly re-lated to the relative structure factors of the crystal orientations.  The diffraction pattern on the exposed film is compared with the known diffraction pattern on one of the standard spherical projection spheres for a specific crystal structure to determine the orientation of the crystal sample.          By replacing the stationary sample support with a rotating sam-ple mount, the hemispherical Laue camera can be used for crystal structure determination in a manner previously pro-vided in conventional Debye-Scherrer cameras.

A depres-sion is formed with the aid of a punch in a plastically deformable metal sheet such as steel, aluminum, copper and the like, while applying controlled counterpressure with the aid of a larger counterpunch so that material displaced from the space between the punches is laid upon the inner bore of a constraining die.  Thus the wall of the depression is formed by purely compressive means.  The base of the depression may then be removed to provide deep flanges of controlled dimensions free of cracks or splits.

It is possible to make a metal from the group molybdenum, nickel, iron, tungsten and copper or an alloy comprising at least one metal from this group, thermally black (black for thermal radiation) and very resistent at high temperatures. This can be done by successive-ly coating this metal or the alloy with a layer of aluminium which is from one to a few /µm thick, heating the metal or the alloy thus coated in a non-reactive atmosphere until the aluminium has reacted with the metal or a metal from the alloy, after which the metal or the alloy is fired in wet hydrogen so that the aluminium is partially oxidized from the compound of the aluminium with the metal or the alloy. In this manner a thermally black surface which can withstand very high temperatures is obtained.
