Abstract: "A CORRUGATED METAL-CLAD SANDWICH PANEL               WITH A WAFER COMPOSITE CORE"     Abstract of the Disclosure A corrugated metal-clad sandwich panel with a wafer composite core is provided.  The single stage process for the panel manufacture involves utilizing a press platen system which is mechanically convertible between a planar and a corrugated configuration.  The metal sheet is first placed on the lower platen which is in the planar configuration.  The wafers and an isocyanate resin in admixture are uniformly distributed over the metal sheet.  Optionally, a second metal sheet is placed over the wafer resin mat.  The platens are biased together to precompress the mat.  Finally, the platens are converted from the planar to the corrugated configuration, thus forming the corrugated metal-clad sandwich panel having a waferboard core in a single stage.

Abstract: Abstract of the Invention An  electrokinetic  process  and  apparatus  employing coherent  radiation-excited  fluorescence  for  detection  is disclosed.    Specifically,  the  detection  of  electrokine-tically-transported target species as said species pass in a support electrolyte through a detection volume can be carried out with improved efficiency when the detection event asso-ciated with the passage of the species through the detection volume is a change in emitted light, in particular fluores-cence,  which emitted light has been generated by a beam of electromagnetic radiation supplied on-column by a coherent source.   The use of coherent radiation source permits the radiation of a well-defined wavelength to be delivered on-column to the sample without hazard and without appreciable loss  of  intensity  and without  unwanted  interference  from scattered  light,  as  compared to incoherent light sources.          The use of coherent radiation increases sensitivity because interference from Raman and Rayleigh scattering is minimized.       This  detection  system allows  mixtures  of  compounds to be analyzed and/or separation with improved efficiency.  It is possible,  using the detection system of this invention,  to detect amount of targets in the range of a femtomole (10-15 moles) or less.

Abstract: In the manufacture of sheet metal elements or strip having a catalytic surface structure, a mixture of skeleton material powder, and of Raney alloy powder is rolled onto the starting sheet metal element or strip substrate, sintered in a reducing atmosphere, whereafter the soluble component of the Raney alloy is dissolved out. To ensure an adequate adherence of the catalytic surface structure, the operation in which the above-mentioned mixture is rolled onto the substrate is accompanied by a simultaneous cold-working of the substrate with a deformation of 20 to 60% within each cold-forming step. The coated sheet metal element or strip substrates or any spherical bodies made therefrom serve as electrodes in electrolytic processes.

Abstract: Therapeutic waistcoat for the treatment of ailments in the cervical and neck-arm region, e.g. cervical syndrome, omarthrose, periarthritis. The waistcoat tightly encloses the entire upper part of the body and has a collar part at least twice as long as the neck. The collar folds down to form a stiff collar; if desired, an additional neck support may be inserted into it. With or without additional neck support, the collar is dimensioned in a way to assure contact pressure by the collar part on the entire neck region up to the jaw and the base of the skull. The fabric of the waistcoat, including the collar part, consists of an electrostatically active knit made of a mix of polyvinyl chloride and acrylic fibres. The supporting effect applied in the neck region in combination with the increased heat effect caused by the contact pressure results in a therapeutic effect in the cervical range which radiates to the areas of the shoulder and elbow joints.

Abstract: The invention provides a strap for the fastening of railroad rails to ties or stringers. The fastening strap is composed of a rod having a vertical rectilinear part and a curved part which forms a spring. The end grips the flange of the rail to be fastened, after being tensioned as a result of the rotation of the strap above a ramp, the lower end of the rectilinear part being equipped with a heel catching on a retaining surface in the tie. The strap has an intermediate bearing point which, during the rotation of the strap, bears on an abutment or on a bearing surface of a metal sole plate. This intermediate bearing point ensures the stability of the strap during its rotation and in its tensioned position and, if an abutment is used, keeps this abutment in place.

Title: C-, t- and s-switches that are mechanically operated by a rotary actuator
Inventor: TSOI PAUL Y
IPC: H01P1/12
Filed: 1990-04-12
Granted: 1992-06-09
Abstract: ABSTRACT A microwave C-, T- or S-switch has an actuator of circular shape that is rotated by a suitable motor.  Each conductor path of the switch contains a connector having two positions, one position connecting the conductor path and a second position interrupting the conductor path.  The conductor paths and connectors are enclosed within a housing and a pin is mounted on each connector and extends outside of the housing through a suitable opening.  Each pin is spring-mounted so that the conductor path is connected when the pin is depressed and interrupted when the pin is released.  The actuator is shaped and mounted to override the pins, the actuator containing one or more ridges and one or more indentations.  When a ridge overrides a pin, the pin is depressed and the conductor path is connected. When an indentation overrides a pin, the pin is released and the conductor path is interrupted.  By properly arranging the size and location of ridges and indentations on the actuator, the conductor paths can be connected or interrupted simply by rotating the actuator through two or more positions.  The switch achieves mass and volume savings over previous switches.  Also, the switch is simple and relatively inexpensive to manufacture.

Granted: 1999-01-19
Abstract: An arrangement of electrically anisotropic high-temperature superconductors (A1, A2) on a non-superconducting metal strip (1) for alternating-current applications, such  as  magnets  and  electrical  machines,  is specified  in the case of which a relatively simple reduction of alternating-current losses is achieved in that at least one strip (A1, A2), deposited as a layer, made  of  a  high-temperature  superconductor,  spirally surrounds this metal strip. The superconducting strip (A1, A2) has a preferred direction in which the critical current density is smaller than in all other directions. In this arrangement, a current (i) flowing through the superconductor flows periodically through regions of the superconductor (A1, A2) that are oriented in the preferred direction and twisted by 180° thereto. These periodic regions limit the length of the eddy currents.        Instead of a spiral winding (A1, A2), it is also possible to use, especially for power cables, a two-layer conductor with grooves and webs arranged periodically along the current direction, in the case of which grooves and webs the current must alternate periodically from one into the other layer.
