Title: Curable polymer compositions comprising polyphenylene  ethers and polyepoxides
Inventor: HALLGREN JOHN EDWARD
IPC: C08J5/24
Filed: 1988-06-09
Granted: 1995-08-29
Abstract: Blends of high molecular weight polyphenylene ethers with various epoxy materials, particularly poly-glycidyl ethers of bisphenolic compounds, are homogeneous at high temperatures and may be cured in the presence of a catalyst such as aluminum tris(acetylacetonate) or zinc bis(acetylacetonate), especially in the additional presence of an accelerator such as a basic nitrogen compound.  The cured compositions have advantageous physical and electrical properties and are useful, for example, for the preparation of printed circuit boards.

Abstract: PASTE-THE-WALL WALLCOVERINGS AND METHOD OF MAKING    ABSTRACT     A paste-the-wall wallcovering has a deep emboss paper  ply adhered  to  a  flat  plastics  ply  having perforations.  The ply can  restrain  the ply against  any significant expansion in the course of hanging and paste drying.  The perforations are regulated on the one hand so that  weight  loss  from  the  hanging  paste  is  not  so excessive that the paper ply becomes softened and, on the other hand, so low that tacking of the wallcovering to the surface  on  which  it  is  to  be  adhered  is  not  unduly delayed.   In making  the wallcovering  the  paper  ply  is moistened  and  embossed  and  allowed  to dry  just  below ambient humidity prior to laminating it to the plastics ply.  The wallcovering may be decorated in the course of manufacture or after hanging.

The generator is responsive to binary signals each having first and second logic levels respectively representing binary "1" and binary "0" and each representing a different one of the binary colors red, green and blue.  Each of the binary signals is introduced to an individual one of transistors in a first plurality.  An energizing voltage is also introduced to the transistors to obtain a flow of current through such transistors in accordance with the logic levels of such input signals and the magnitude of the energizing voltage.  A substantially constant current is provided at first particular times and a reference voltage is provided at other times.  An impedance may be common to the circuit for the substantially constant current and the reference voltage.  A first control is responsive to the constant current to maintain the energizing voltage at a substantially constant value.  A second control is responsive to the reference voltage to maintain the energizing voltage at the substantially constant value.  When the reference voltage is produced, the production of the substantially  constant voltage from the constant current is overridden.  The first and second controls for each of the different colors are disposed in an electrical circuit to provide an output from the circuit only in accordance with the logic levels of the binary signals.  The first and second controls may respectively include transistors in second and third pluralities.                      * * * * * * * * *

Abstract: The invention relates to a method of forming a joint of high electrical  conductivity between a metallic contact piece (17) and a metallic form part (12) comprising a groove (16) or a recess.  In order that a firm joint with good electrical conductivity could be provided between the contact piece and the form part, the method according to the invention is mainly characterized in that the contact piece is a tubular body (17) attached to the form part (12) by friction welding, whereby the tubular body is rotated about its longitudinal  axis  while  the  form part  is  pressed against the outer surface of the tubular body so that the tubular body is welded to the groove (16) or recess of the form part due to the heat of friction. The invention is also concerned with a current conduction to be used in the electro-chemical purification of metals. The current conductor comprises a rodlike conducting body (12, 12') of an aluminium-based material of high electrical conductivity and comprising a groove (16) or recess, a contact piece (15, 15') of copper being welded to the rodlike conducting body.

Title: Method for calibrating dielectric permittivity log measurements
Inventor: SHERMAN MICHAEL M
IPC: G01V3/18
Filed: 1989-07-20
Granted: 1992-05-26
Abstract: ABSTRACT OF THE DISCLOSURE         Two types of dielectric logging tools are in use:  the pad type which operates in the 100 to 1100 MHz frequency range and the mandrel type, which typically operates in the 10 to 100 MHz range.  Although both types of tools make the same measurement, the lower frequency tools have a greater depth of investigation and therefore have different applications than the higher frequency pad devices.  However, logs measured with 10 to 100 MHz tools are more difficult to interpret because of the large fre-quency-dependent dispersion of the dielectric permittivity below 100 MHz.  A model of the frequency dependence of the dielectric permittivity has now been developed that pre-dicts permittivities in the 10 to 100 MHz range from the more easily obtained measurements in the 100 to 1300 MHz range.  The predicted permittivities are used to calculate fit parameters for interpretation equations normally used for the higher frequency pad devices.  Once these fit parameters are known for measurements in the 10 to 100 MHz range, then the high frequency interpretation methods can be applied in the 10 to 100 MHz range.  Thus, by combining the model for the frequency dependence of the dielectric permittivity with existing interpretation methods used for 100 to 1100 MHz tools, an improved interpretation of die-lectric logging measurements in the 10 to 100 MHz range is possible.
