Abstract: Abstract of the Disclosure Cutaneous methods for measurement of substrates in mammalian subjects are disclosed.  A condition of the skin is used to measure a number of important substance which diffuse through the skin or are present underneath the skin in the blood or tissue. According to the technique, an enzyme whose activity is specific for a particular substance or substrate is placed on, in or under the skin for reaction.  The condition of the skin is that detected by suitable means as a measure of the amount of the substrate in the body.  For instance, the enzymatic reaction or by-product of the reaction is detected directly through the skin as a measure of the amount of substrate.  Polarographic electrodes or enzyme electrodes are employed as skin-contact analyzers in the trans-cutaneous measurement of oxygen or hydrogen peroxide to quanti-tatively determine blood substances such as glucose and alcohol. In a preferred quantitative technique, the skin is arterialized, i.e., heated or otherwise treated to arterialize the skin capil-laries when the measurements are made.  Colorimetric detection methods are also employed.

Abstract: SHELL AND TUBE MOISTURE SEPARATOR  REHEATER WITH OUTLET ORIFICING          Abstract of the Disclosure Shell and tube heat exchangers achieve greater efficiency and substantially eliminate instabilities due to condensate subcooling by the location of flow restricting orifices at the outlet ends of heat exchanger tubes adjacent to the outlet header.  Outlet orificing preferentially passes liquid condensate so as to prevent accumulation of condensate within the tubes and permits a higher tubeside temperature, even in themost heavily loaded tubes.  In a two-pass configuration all tubes are outlet orificed.  In a four-pass system, the most heavily loaded tubes (second pass) are orificed, although all tubes may be outlet orificed.  Outlet orificing may be used in conjunction with inlet orificing which is used to provide greatest mass flow of tubeside steam to most heavily loaded tubes.  Outlet orificing may be used in connection with vertical or horizontal U tube configura-tions.  Preferred embodiment is utilized in a moisture separator reheater for use with steam turbines to reheat steam for later turbine stages.  Orifices are restricted diameter apertured plugs in heat exchanger tubes located within the tubesheet adjacent to the header.

Abstract: CONTACT TECHNIQUE FOR ELECTRICAL CIRCUITRY                       . ABSTRACT     In electrical circuitry, and particularly super-conducting circuitry including Josephson tunnelling devices, it is often necessary to provide solder contacts to electrical lines, where the electrical lines would be destroyed if there were interdiffusion between the lines and the solder.  To avoid this problem, a laterally extending metallic layer is used as a diffusion barrier between the solder land and the electrical line which can be a superconducting line. The diffusion barrier is comprised of a re-fractory metal which has a first portion electrically contacting the solder land and a second, laterally displaced portion electrically contacting the elec-trical line.  An insulating protective layer on the diffusion barrier layer separates the solder land and the electrical line.  In a specific embodiment, the superconducting electrical line is comprised of an alloy of lead while the diffusion barrier is comprised of niobium, and the solder alloy is a low melting point alloy, typically comprised of indium, bismuth,

Abstract: Abstract of the Disclosure Disclosed  is  a  well  packer  for  releasable setting within a well conduitl including a seal assembly for sealing the packer to the conduit and an anchor assembly for anchoring the packer to the conduit.  The packer is set in stages by hydraulic pressure.  The seal assembly  is extended,  and  locked,  in  sealing  configuration; the anchor assembly is then set,  and locked,  in gripping engagement with the conduit.  The packer is released by longitudinal movement of a central mandrel relative to the seal and anchoring assemblies.  The release of the packer also occurs in stages, with the seal assembly unlocked and released  from its  set configuration  followed  by like operations relative to the anchor assembly.  A hold-down system prevents premature release of the packer by securing the mandrel against such relative longitudinal movement.
