Abstract: ABSTRACT          SURGICAL DRESSING    A moisture vapour permeable, adhesive surgical dressing is described which comprises a continuous film of a hydrophilic polymer which has a moisture vapour permeability which is greater when in contact with water than when not in contact with water and which is attached around its edges to a water transmitting film so as to form a sealed portion into which exudate may pass from an exuding wound.  The water transmitting film comprises a backing layer and an adhesive layer on the side remote from the continuous film.  The adhesive layer is suitable for adhering the dressing to the skin.  The water transmitting film allows or is adapted to allow access of water to the film when in contact with water so that when used on an exuding wound the high moisture vapour permeability of the continuous film allows water to evaporate through the dressing and prevents the dressing forming a blister.    The low moisture vapour permeability of the film when not in contact with water makes the dressing suitable for use on non-exuding wounds.  Preferably a second water transmitting film is present between the continuous film and the water transmitting layer.

Abstract: SINGLE WELL STIMULATION FOR THE RECOVERY OF LIQUID HYDROCARBONS FROM SUBSURFACE FORMATIONS                 ABSTRACT OF THE DISCLOSURE        Water is vaporized in an annular upper region of a subsurface formation into which a borehole extends from the surface.  This creates a substantially nonconducting dielectric in such region extending outwardly from the borehole.  Such vaporization is preferably achieved by the application of electrical power to an electrode disposed in the borehole.  Liquid is produced through the borehole from a lower region of the formation to cool the lower region near the borehole and maintain an electrically conductive path between the formation and the electrode in such lower region through which electrical power is applied to the formation.

Abstract: ELECTRONIC DEVICE METHOD USING A LEADFRAME WITH           AN INTEGRAL MOLD VENT MEANS                           ABSTRACT      An improved ladder-type leadframe is described for use in connection with the plastic encapsulation of electronic devices, particularly semiconductor devices.  The side rails of the leadframe, adjacent the die bonding flag, are grooved to provide, integral with the leadframe, a gas vent to relieve gas pressure inside the mold cavity during plastic encapsulation.  By making the vent channels a part of the leadframe, rather than a part of the mold itself, as has been done in the prior art, the problems associated with mold vent blockage due to leadframe burrs, with cleaning the small vent channels found in a prior art mold, and with mold wear associated with those channels, are avoided.  This reduces the cost of the molding operation, extends mold life, and improves product quality, and is accomplished without any significant increase in the cost of the leadframes.

Abstract: ABSTRACT     Pnictide thin films, particularly phosphorus, grown on III-V semiconductors, particularly InP, GaP, and GaAs, are amorphous and have a novel layer-like, puckered sheet-like local order.  The thin films are typically 400 Angstroms thick and grown preferably by molecular beam deposition, although other processes such as vacuum evaporation, sput-tering,  chemical vapor deposition,  and deposition  from a liquid melt may be used.  The layers are grown on the <100>          <110> , and <111>  surfaces of the III-V crystals.  The pnictide layer reduces the density of surface states, and allows the depletion layer  to be modulated,  the  surface barrier reduced, the electron concentration at the surface increased,  and  there  is  a  decrease  in  the  surface recombination   velocity   and   an   increase   in   the photoluminescence intensity.  The layers may be utilized in MIS and Metal-semiconductor  (Schottky) devices for example to insulate and passivate MISFETS, to passivate MESFETS, to reduce the surface current component of the reverse bias dark current in P-I-N and avalanche diodes, and to improve performance  of  opto-electronic  devices  such  as  light emitting diodes,  lasers,  solar cells, photo cathodes and photo  detectors.   The  pnictide  layer may be  applied  to intermetallic and compound semiconductors having a pnictide component.   The  pnictides  may  be  phosphorus,  arsenic, antimony or bismuth, or combinations thereof.

Abstract: ABSTRACT OF THE DISCLOSURE      The disclosed embodiments enable address translations for a virtual machine in the TLB of a CPU to be retained from exiting a SIE (start interpretive execution) instruction to the next SIE entry to interpretive execution for the same guest (virtual machine CPU).      Conditions are defined which determine when guest TLB entries must be invalidated.  These conditions require invalidation of guest TLB entries only within and on entry to interpretive execution.  A single invalidation of guest TLB entries on entry to interpretive execution is required for any number of conditions recognized while a CPU is not in interpretive execution state.  For a guest in a virtual multi-processor (MP) machine, an interlock is provided lo allow the use of guest virtual addresses by host instruction simulation and the need for guest TLB invalidation is broadcast to all other real CPUs in a real MP system so that all guest TLBs on all real CPUs can be invalidated to maintain integrity.  No broadcast or interlock is needed for a guest in a virtual uni-processor (UP) machine.

Abstract: METHOD OF REPAIRING CRACKED         THIN METAL PART            Abstract of the Disclosure Thin metal parts such as one eighth inch or less cast iron or one quarter inch or less cast aluminum are repaired by drilling a series of overlapping holes ex-tending generally perpendicular to the crack at each end of the crack and at spaced locations along the crack. A lock of the general outline of the series of overlapping holes is fixedly secured in each of the  series of over-lapping holes.  At least one hole having a diameter no greater than 0.200 inches is drilled in the crack between the locks so that the hole overlaps a portion of one of the locks.  The hole is tapped with a tap having at least 27 threads per inch and a plug having the same number of threads per inch as the tapped hole is secured in the tapped hole thereby pre-stressing the locks and filling the gap of the crack.  The plug is torqued until the torquing force exceeds the strength of the plug thereby snapping off a portion of the plug which extends beyond the surface of the part.  Additional holes are drilled, tapped and plugged along the crack to completely fill the gap of the crack. Preferrably, the tapped holes and plugs are tapered, the tapered plug having a maximum diameter of about 0.205 inches and a minimum diameter of about 0.155 inches, and the tapped hole and plug having 32 threads per inch.

Abstract: ABSTRACT              The single lever control for operating the clutch and throttle of a marine motor has a support on which a sleeve is mounted on a pivot.  A rod is mounted in the sleeve for axial movement.  The distal end of the rod is actuated to move the rod and the sleeve about the pivot and also to move the rod axially relative to said sleeve.  An actuating arm and a cam track cooperate to move the rod and sleeve in an arc about the pivot between first and second positions between which the clutch is operated by an operator actuated by rotation of the arm about its pivot.  The actuating arm moves the rod axially relative to said sleeve when the arm is beyond the clutch operating range.  The rod is connected to the throttle.  A friction device acts on the rod to resist axial movement of the rod relative to the sleeve.  The friction load resists change of the throttle setting but has no affect on clutch operation.

Abstract: METHOD OF BONDING SILVER TO GLASS AND MIRRORS PRODUCED ACCORDING TO THIS METHOD A method for adhering silver to a glass substrate for producing mirrors includes attaining a silicon enriched substrate surface by reducing the oxygen therein in a vacuum and then vacuum depositing a silver layer onto the silicon enriched surface. The silicon enrichment can be attained by electron beam bombardment. It can also be attained by depositing a metal, such as aluminum, on the substrate surface, allowing the metal to oxidize by pulling oxygen from the substrate surface, thereby leaving a silicon enriched surface, and then etching or eroding the metal oxide layer away to expose the silicon enriched surface. Ultraviolet rays can be used to maintain dangling silicon bonds on the enriched surface until covalent bonding with the silver can occur. This disclosure also includes encapsulated mirrors with diffusion layers built therein. One of these mirrors is assembled on a polymer substrate.
