Abstract: A B S T R A C T     A method for producing substantially pure carbon dioxide in a single phase at the surface from a subterranean formation.  A pump means, e.g., electrically driven, sub-mergible, centrifugal pump system, is positioned downhole in a carbon dioxide production well.  The carbon dioxide flows from the formation to the inlet of the pump means wherein the carbon dioxide is compressed to raise the pressure to values greater than the critical pressure of the produced carbon dioxide plus the amount of pressure that the carbon dioxide will lose due to (a) the static fluid head above the pump means and (b) flow friction from the pump means to a central processing and compression station on the surface. By so boosting the pressure within the well, the carbon dioxide will be produced at the surface at a pressure greater than the critical pressure of the produced carbon dioxide, thereby insuring the carbon dioxide will be in a single phase, supercritical state.

Abstract: ABSTRACT OF THE DISCLOSURE           A permeable base transistor including a metal base layer embedded in a semiconductor crystal to separate collector and emitter regions and form a Schottky barrier with each is disclosed. The metal base layer has at least one opening through which the crystal semiconductor joins the collector and emitter regions.  Ohmic contacts are made to the emitter and collector regions.  The width of all openings in the base layer is of the order of the zero bias depletion width corresponding to the carrier concentration in the opening.  The thickness of the metal layer is in the order of 10% of this zero bias depletion width,  As a result, a potential barrier in each opening limits current flow over the lower portion of the bias range.  With increasing forward base bias the potential in the openings, which is lower than along the metal of the base layer, is lowered sufficiently to permit substan-tial increase in the barrier limited current flow from the collector to emitter.  A method of fabricating this transistor as well as methods for forming integrated cir-cuit structures including the transistor are also dis-closed.

Abstract: ABSTRACT      Semiconducting material for example p-type Ge, p-type Si and the like, is formed into a thin foil, a few atoms thick, preferably by depositing the material on an atomically flat ([110] plane) surface of an in-sulating semiconductor substrate, for example GaAs, ZnSe and the like.  The materials used for the foil are of a group characterized by re-entrant constant energy level contours and negative effective charge carrier masses.  The foil has length and width dimensions much greater than the thickness. An electric bias field is applied across the length of the foil tending to shift the charge carrier population into a sector of negative transverse mass.  In this manner the resistance across the width of the foil becomes negative and electric energy is delivered to external circuitry connected across the width of the foil.  A stacked structure of two or more layers connected in parallel is contemplated for generating larger currents as needed for amplifying and oscillating circuits.

Abstract: U-Wp-2480  Wacker PROCESS FOR THE MANUFACTURE OF SUBSTANTIALLY PORE-FREE SHAPED POLYCRYSTALLINE ARTICLES BY ISOSTATTC HOT-PRESSING IN GLASS CASINGS            ABSTRACT     The invention relates to a process for the manufacture of substantially pore-free shaped articles of polycrystalline material such as aluminium oxide, titanium boride, silicon nitride or silicon carbide, in which pulverulent materials or preformed articles having pores open towards the surface, in a vacuum-tight sealed glass casing that has a viscosity of less than 106 Pas at the pressing temperature employed, are isostatically hot-pressed in a high-pressure autoclave using an inert gas as pressure-transfer medium.  By being embedded in a flowable pile or by having a layer applied to them in the form of a suspension, the glass-encased powders or articles are brought into contact with a heat-resistant pulverulent material that, upon softening of the glass casing, penetrates into the surface of the glass or reacts with it, with the result that the glass casing is reinforced from the outside at the pressing temperature, As pulverulent materials, there may be used titanium boride, graphite, SiC or boron nitride, which do not react with the glass casing, or glass powder or silica, which react with the glass casing to form a glass melt of at least the same viscosity as, or of a higher viscosity than, the glass casing.

Abstract: ABSTRACT    An apparatus and methods for producing a transmission barrier for inhibiting propagation of light into still unimaged transparent portions of microfiche recording system intermediate film strips (71) by light-piping action are described.          The barrier serves to optically isolate the sub-sequently-to-be-imaged still unexposed portion of the film strip (71) in a dispensing film head from the illumination used to transfer the previously developed image on the exposed portion of the strip (71) onto a permanent recording medium, such as a microfiche film card (20).  In one exemplary form of the invention, the barrier regions are photographically produced dark bands (260) or lines (262) between the longitudinally spaced areas of the film strip to be imaged.  These bands (260) or lines (262) are preferably created as latent images during the initial exposure of the intermediate film (71) and subsequently developed at the same time as the record image.  Alternative embodiments include placing bands or lines of light absorbing material on the film strip or by serrating or otherwise locally deforming the in-termediate film strip to produce the barrier re-gions, the serrations (274) serving to spoil total internal reflection in the film.  Long term fogging of the film by normal ambient light is dealt with by providing an automatic film payout feature.          Particular applications to archival microfiche systems involving the intermediate film strip (71) carrying a transferable image are described.  An apparatus for using pre-formed barriers on the film strip (71) to regulate film advance is de-scribed.

Abstract: METHOD AND APPARATUS FOR PRODUCING      A HEAT EXCHANGER TUBE                   ABSTRACT OF THE DISCLOSURE           Method and apparatus is disclosed for producing a spine fin heat exchanger in which the density of the spine fins is greater along the portions of the passes within the pattern of high flow of air or the like across the heat exchanger.  Those portions of the tubing at the bends and outside such pattern are formed with a lower spine fin density.  Such lower density outside the patterns and at the bends does not materially reduce the overall heat exchange capacity of the heat exchanger, and results in a heat exchanger where less material and time are required to form the heat exchanger without any significant loss in its capacity.  The heat exchanger is preferably formed by chang-ing the rate of feed of the tube as it feeds through the winding head to increase the amount of stretch of the spine fin strip along the zones of low density compared to the amount of stretch in the strip along the zone of high den-sity.  Consequently, the same amount of material is required for each wrap along both zones.
