Abstract: GROWTH OF STRUCTURES BASED ON GROUP IV      SEMICONDUCTOR MATERIALS            Abstract of the Disclosure Single crystal layers of Group IV semiconductor materials, such as silicon, are grown on insulating substrates.  The fabrication of this structure is achieved by forming on a single crystal substrate a layer of an insulating material, such as silicon oxide.  A small via hole is produced in the insulating layer to leave a portion of the underlying substrate uncovered,  A precursor material is deposited on the insulating layer so that it covers at least a portion of the insulating layer and also contacts the substrate at the via hole.  The precursor layer is then formed into a single crystal by inducing growth on the substrate at the via hole and propagating this growth through the precursor layer.

Abstract: A B S T R A C T     The mould features on its work face a thermally insulating protective layer of sub-micron metal oxide particles.     The coating can be applied by spraying an aqueous sol of a metal oxide onto the mould work face which has been heated to at least 60°C.     The use of sub-micron sized metal oxide particles enables the formation of a protective coating of very low density and consequently very low thermal conductivity. The coating can furthermore be deposited very economically, and like-wise removed again.

Abstract: Abstract A line protector and associated termination structure comprises a module having printed circuit board wiring internally thereof and also as outwardly projecting contacts adapted for connection to a printed circuit board edge connector.  An insulator is disposed against the printed circuit board and is slidable therealong and optionally serves to interrupt the tip in and ring in sides of the telephone line when it is desired to place the protector module in the so-called "detent" position.  The protector module may be restored to its normal operating condition by retracting the insulator or by removing the module entirely from its position in the connector and then reinserting the module fully into the connector.  This latter operation automatically slides the insulator to its non-detent position.

Abstract: ABSTRACT OF THE DISCLOSURE      A   method   for  achieving   printed   circuit  (PC) board-level testability through electronic component-level design using  available technological methods  to effect a state  of  transparency   during  test,  allowing  precise verification  and  diagnosis  on  a component-by-component basic.   Applicable  to  a greater  variety  of electronic products  than  other  test methods,  and  not appreciably constraining  functional design,  this approach inherently avoids  obstacles  which  prevent  other  techniques  from fulfilling their objectives.  This method is applicable to analog or  digital electronic components  and circuits and results in the ability  to largely combine component level and board  level test development efforts,  a reduction in the need  for exhaustive component testing  prior to board assembly,   the   applicability   of   a   single   tester configuration to a number of product types, the ability to substitute a verified component  for a suspect one without removal,  and the  ability to  detect marginally operative components   which    have   not   yet    affected   board functionality.

Abstract: "PROCESS AND APPARATUS FOR THE BIOLOGICAL PURIFICATION OF WASTEWATER"               ABSTRACT OF THE DISCLOSURE   This invention relates to a process and apparatus for the biological purification of wastewater in a reactor in the presence of biomass, and with the use of carrier materials, such as polyurethane foam par-ticles, as a settling surface for the biomass.  The carrier materials are employed in an aera-tion system in an oxygenation tank or reactor of the type wherein surface aerators, immersed aerators, or injectors are employed.  Typically the carrier material would be subjected to high shear forces which in turn would cause a reduction in its structural strength.  Thus, to prevent such carrier materials from being damaged while maintaining them in the reactor for the biomass independently of the type of aeration employed, a zone free of carrier material is provided in the reactor.  The wastewater from the carrier-free zone is aerated and then employed to aerate all of the wastewater in the reactor.
