Abstract: NOISE REDUCTION IN COMPANDING ARRANGEMENTS     Abstract of the Disclosure In a companding arrangement, the presence of a tone in only one of the two transmission directions is detected.  Upon such detection, for example during set-up of a telephone call via a satellite transmission channel, the tone is compressed or expanded, depending on its transmission direction, separately from the remainder of the signal using a second compander.  Companding is thus effected using two companders operating at different amplitude levels, with a consequent noise level reduction.  A single bandpass filter is used to separate the detected tone, switches being controlled by the tone detection to couple the bandpass filter selectively for operation in either transmission direction.     -i-

Abstract: METHOD FOR FORMING A PLATINUM RESISTANCE THERMOMETER   ABSTRACT OF THE DISCLOSURE          A platinum resistance thermometer is formed in a process which includes the defining of a path for the resistance thermometer in an inert material deposited in a layer on the substrate.  The substrate surface  is  exposed  in  the  path,  and  the  inert material forms a negative pattern for the  path.  The resistive  material  for  the  thermometer  is  then deposited on both the substrate  surface exposed  in the path and on the surfaces of the inert material remaining on the  substrate.   After  this,  the  inert material is etched away,  and the resistive material deposited on top of the inert material is then loose and  can  be  removed  leaving  a  strip  of  resistive material  in  the  desired  path  for  forming  the resistive   thermometer.   The   strip   has    low contamination and impurities to more easily reach the desired temperature coefficent of resistance of the strip forming the thermometer.

Abstract: Abstract of the Disclosure A secondary battery, such as a nickel-hydrogen (NiH2) cell, has a first and a second cell stack, each cantilevered from opposite sides of a weld ring.  The weld ring is located at the approximate center or middle of a pressure vessel composed of two half sections which are welded to opposite sides of the weld ring.  The cell stacks are essentially unsupported at their outer ends.  Electrical current carriers are received in longitudinal channels formed on opposite sides of an axially located cell stack support member, on which the cell elements are cap-tured.  Cantilever mounting of two cell stacks from a central weld ring is found to improve the integrating and durability of the cell.  It also increases the energy capacity of the battery through the ability to add more cells through the use of axially longer pressure vessels, increasing the capacity of the battery.  Location of the weld ring between the pair of cell stacks improves heat transfer between the cells and the pressure vessel during discharge.

Abstract: ABSTRACT OF THE DISCLOSURE           Disclosed is a granular multi-cellular glass and  a method  for  producing the  same.   An ordinary multi-cellular  glass  grain  having  relatively  low moisture  content ratio  was  prepared  as  starling material.  The glass grain is then dipped in water or alkali solution for eluting or dealkali treatment. By the  dipping,  soluble  alkali  components  are  mainly eluted  from a surface  layer  and cell walls of the glass grain.  Thus produced multi-cellular glass grain provides increased moisture content ratio because of the formation of micropores at the layer and cell wall portions.   Disclosed  also  are  control,  of  physical properties  of  the multi-cellular  glass  grain  for controlling  specific  gravity,  pore  volume  and  pore diameter thereof.  By these controls, resultant glass grain is provided with desirable physical properties available for a microcarrier for immobilizing microbe therein.
