Abstract: ABSTRACT OF THE INVENTION      A method for achieving elevated circulating plasmin levels and thus causing the dissolution of blood clots is disclosed.          This  method  is  particularly  suited  for  the  treatment  of myocardial infarctions and other clotting disorders. This method involves in two phases the elevation of endogenous, circulating tissue  plasminogen  activator   (tPA)   levels  through  the administration of basic placenta angiogenic factor (PAF).  In the first phase, a relatively high circulating concentration of basic PAF effects the release of tPA from sites in the vascular bed into the circulation.  In the second phase, lower circulating concentrations are maintained for a period of time necessary to induce the synthesis and secretion of tPA.  This induction will elevate the circulating concentrations of tPA,  thus causing increases in the circulating levels of plasmin, an enzyme capable of dissolving blood clots.  A method for accomplishing similar purposes is also disclosed which involves the administration of basic PAF in conjunction with heparin as the active ingredients in a pharmaceutical preparation.

Abstract: ROTARY SCROLL MACHINE WITH RADIAL CLEARANCE           CONTROL AND METHOD OF MANUFACTURING                 ABSTRACT OF THE DISCLOSURE           A scroll compressor can be provided with different wrap thickness to compensate for the different material proper-ties of the orbiting and fixed scroll elements.  The concept of different wrap thicknesses also aids in the select-fitting of parts and in the provision of and adjustment of a clear-ance or spacing between the wrap elements.  Additionally, in the manufacture of a scroll compressor, the total wrap thickness of the two wraps is kept constant within narrow tolerances while the individual wrap thicknesses are allowed to vary over a predetermined range.  The cutting tools used are sized such that even if they differ in their cutting diameters, the combined cutting diameters, and therefore the total wrap thickness, are constant within narrow toleranc-es.  This permits the tools to be used and resharpened until their cutting diameters fall below the minimum acceptable diameter.

Abstract: ABSTRACT OF THE DISCLOSURE           A device fixed on a measuring instrument provides access to the terminals of a microwave component in order to measure scattering, noise or output power parameters.  In order to minimize the length of connections between the access lines of the device and the input and output terminals of the component to be measured, two access blocks which carry the access lines are positionally adjustable with respect to the component to be measured in such a manner as to permit two degrees of freedom in relative-spacing displacement and in lateral translational displacement.  Irrespective of the type of component to be measured (chip, package, hybrid circuit), the component is carried by an insert block placed between the two access blocks and having dimensions equal to those of the component.

Abstract: ABSTRACT OF THE DISCLOSURE           A modular, expandable, low-weight electric motor has a cylindrical, non-magnetic casing formed in axially-aligned sections. The casing sections are releasably connected to define a unitary structure with a polygonal exterior surface and a circular interior surface. Separate U-shaped stator pole assemblies are releasably mounted against the exterior of the casing, each casing section carrying the poles associated with a different motor phase. The poles extend through apertures into the interior of the casing, and have active pole faces which are curved and substantially flush with the circular interior surface of the casing. A modular rotor is mounted in the interior of the casing and carries magnetic elements in axially spaced-apart sets corresponding to each motor phase. The active faces of the magnetic elements are curved and oriented in a cylindrical arrangement. During each rotation of the rotor, the pole faces of each motor phase simultaneously and repeatedly register with the associated magnetic element faces forming air gaps, and the magnetic elements simultaneously complete local magnetic circuits with each stator pole assembly. The sets of magnetic rotor elements are indexed circumferentially relative to one another such that the motor is self-starting.

Title: Stationary induction apparatus
Inventor: YAMAGUCHI KIMIAKI
IPC: H05B6/80
Filed: 1988-05-13
Granted: 1992-11-03
Abstract: Abstract of the Disclosure A stationary induction apparatus for supplying and receiving high frequency power of several tens of KHz employs a partition wall made of a non-magnetic metallic foil with a thickness less than 1/10 the depth of penetration at the frequency used for electromagnetic induction.  The wall separates the supply side (primary side) from the receiving side (secondary side), so that the stationary induction apparatus is not impaired in its function as an induction apparatus.  On the other hand the wall can electromagnetically shield the primary side from the secondary side.  As a result, the secondary side of a boosting transformer for a magnetron can be placed within a shielding casing, thus realizing a light, compact and inexpensive microwave generating device for use in an electronic oven.

Title: Method and apparatus for generating a mesh for finite element analysis
Inventor: WEISS JONATHAN
IPC: G06F17/50
Filed: 1989-02-01
Granted: 1992-05-19
Abstract: METHOD AND APPARATUS FOR GENERATING A MESH FOR FINITE ELEMENT ANALYSIS             ABSTRACT The method of mesh generation comprises a two-step automatic process that requires no user input once a geometric representation of the object has been provided to the apparatus.  In the method, the object geometry is first defined in terms of object (subdomain) points, wherein each subdomain is a separate geometric region of the object such as a printed circuit board, a hole in the board, and a component mounted on the board.  Bounding points defining a frame around the object geometry are then generated for producing a mesh consisting of at least one element.  From the object points and the bounding points an initial mesh of elements is automatically generated according to a unique algorithm.  In the second step of the process, each element in this mesh is then individually examined to determine if it meets a predetermined standard of acceptability and, if not, is refined.  This process step employs a rule-based expert system to add additional points to the mesh at automatically determined locations for further mesh generation according to the unique algorithm employed.  The steps of refinement repeat until each element in the mesh meets the acceptability standard or is considered no longer refinable.
