Abstract: ABSTRACT      A hermetic compressor discharge line thermal block is hermetically coupled in the discharge line between a condenser and compressor adjacent to the discharge outlet of the compressor.  The device is formed to define a well for removably receiving a heating element, and has a hermetically sealed chamber substantially surrounding the heater well and electric heating element.  Upon compressor shutdown, liquid refrigerant migrating from the condenser partially fills the chamber, thereby decreasing the temperature of the heating element below a predeter-mined temperature, thereby causing the heating element to become electrically conductive to supply heat to the chamber to evaporate the liquid refrigerant therein and to prevent further accumulation of liquid.  If a positive temperature coefficient heater is used, after thermal stabilization and during compressor operation, the heat generated either by the compressor or by the heating element itself raises the temperature of the element, thereby causing the heating element to become substantially less electrically conductive to reduce the supply of heat to the chamber.  The discharge line thermal block device prevents the migration of liquid refrigerant from the condenser to the compressor to thereby prevent slugging during compressor start-up.

Abstract: 16                  50,052 ABSTRACT OF THE DISCLOSURE This invention relates to an electric-arc fired blast  furnace  system  for the reduction of iron-bearing material utilizing electric-arc heated air containing a reducing  gas  or  carbon-containing  fuel  allowing for  a decrease in the amount of coke normally used in the reduc-tion  process.   The  excess  reducing  gases  exiting  the furnace are utilized as a source of power via a system consisting of turbines,  compressors and a heat exchanger to drive the  electrical  generators  which  are  used  to provide electricity to the arc heaters.  This arrangement forms an essentially closed loop furnace system for metal reduction.   Injection  of  finely-divided  coal  into  the arc-heated air to provide reductants is also employed.

Abstract: INVENTOR   :  LEHMAN T. REED          TITLE      :  ELECTRIC POWER SUPPLYING WELL HEAD ASSEMBLY          DOCKET NO  :  B-2760-1 ABSTRACT OF THE INVENTION     A well head assembly that terminates on the upper end in a horizontal mounting flange on which the flange of a christmas tree array of valves may be seal-ingly mounted to control the flow of fluid from the well associated therewith, and the well head assembly including slidably engageable first and second electrical conducting cartridges below the mounting flange for supplying electric power to a number of insulated electrical conductors that extend downwardly in the well to an electric motor driven down hole pump or other electrical apparatus.  The posit-ioning of the christmas tree array of valves at a minimum height relative to the well head is most desirable in those situations where a number of wells are drilled close together, such as on an off shore island, and equip-ment must be periodically moved over the array of valves for maintenance or drilling purposes.  The well head assembly also includes means for pressurizing a normally open pressure actuated valve in communication with a tubing string operatively associated with the assembly to place the valve in a closed position.  Closing of the valve eliminates the possibility of continued undesired fluid discharge from the well in the event of a catasrophe or malfunctioning of the well.

Abstract: Method of Making a Folded Up Egg Pack In an egg box made from slitted cardboard blanks of which one provides wave strips joined only at their wave crests for folding around to make pockets for the eggs and the other blank provides flat bottom and side panel or cover strips which brace the wave strips by being glued to the wave trough bottoms of the wave strips, top cover strips respectively glued to the half width wave strips that come together(when the top wave strips are folded around the eggs already packed in the pockets previously formed,)do not both correspond in width to the top wave strips,but one of them has an overlapping free edge the underside of which is bonded adhesively to the other top panel strip.  The adhesive bonding is done with a hot-sticking adhesive which when cooled without being covered is no longer sticky.  The adhesive is laid down in strips on the wider and shorter blank which provides the cover strips at locations corresponding to the wave trough bottoms that are to be glued on.  While it is hot the longer and narrower wave blank, bent into waves, is glued on, leaving the edge portion of the wider blank with spaced cross-ribbons of adhesive which are allowed to cool so that they are no longer sticky. The glued blanks are then filled at a packing station but before they are folded to make pockets, for the eggs, the free edge strip is heated with hot air to soften the adhesive ribbons and then the box is set up and filled and after the top of the box is folded into place, the overlapping free edge strip is pressed against the underlying cover strip to stick the two together.  When the adhesive has cooled the pack is secured.

Abstract: ABSTRACT      A method is described for editing graphic objects in an interactive draw graphic system which selectively displays a menu of available editing actions in re-sponse to operation of one mouse button by the operator and allows the operator to cursor select the specific edit action from the menu to be made active by operat-ing a second mouse key.  The operator may also cursor select the object to be edited by operation of the second mouse key.  Once the editing action is selected and made active, the menu is hidden (not displayed) and the editing action remains active in the system until positive steps are taken by the operator to either terminate the edit funciton or change the active edit-ing action.  The operator, therefore, does not have to return to the selection process after each specific editing operation.  The previous editing operation is implied for the next edit operation.

Abstract: Abstract A new method for fabricating semiconductor devices, especially CMOS devices, as well as the resulting devices, is disclosed.  The method involves incorporating dopants into a semiconductor substrate (e.g. 10) through a region (e.g. 50) of the substrate surface (e.g. 20), and diffusing the implanted dopants into the substrate to form a tub.  Prior to the diffusion step, a trench (e.g. 80) is formed in, and extending beneath, the surface which partially or completely encircles the region.  The trench serves to prevent the formation, or reduce the size, of a relatively low dopant concentration region, which would otherwise lead to undesirable leakage currents in the completed CMOS device, and prevents latchup.

Abstract: RING OF LIGHT LASER OPTICS SYSTEM                         Abstract This invention provides a simplified laser optics system for generating a ring-shaped beam of laser radiation which is used for contouring and severing a curved, particularly a dome-shaped, article such as a silicone elastomer contact lens from a workpiece.  The laser optics system consists essentially of a focusing element having a convex surface which receives a circular beam of laser radiation and an opposed conical surface forming an axicon which element transforms the circular beam into a ring-shaped beam of laser radiation.  The ring-shaped beam is received by a reflective element having a conical reflective surface which causes the beam to impinge upon the curved workpiece surface, preferably at an angle which is substantially perpendicular to the workpiece surface, to accomplish edge contouring and severing of the article from the workpiece.
