Abstract: Abstract:       A process for immobilizing adsorbent carbon particles and forming a self-supporting structure of high compressive strength therefrom is described in which the self-supporting structure substantially eliminates the formation of carbon fines while re-taining the adsorption characteristics of the carbon particles.  The process for immobilizing the adsorb-ent carbon particles in the self-supporting structure comprises the steps of:     (a) mixing carbon particles, a major portion of which has particle sizes in the range of from about 200 to about 2,000 microns, with a powdered polymeric binding material, preferably a thermoplastic material having a solid-liquid transition stage, in an amount of about 5 to about 20 percent by weight, based on the weight of the total mixture, a major portion of the particles of the polymeric binding material hav-ing particle sizes in the range of about 8 to about 30 microns, to form a mixture of the carbon particles partially coated with the polymeric binding material;     (b) placing the mixture in a container of a desired shape; and (c) applying a pressure of up to about 400 psi while the mixture is at an elevated temperature, this temperature being near the solid-liquid transition stage (when the polymeric binding material is a ther-moplastic material), thereby forming the structure and immobilizing the particles.

Abstract: ABSTRACT         The invention discloses a method of producing viscous immobile oil from a subsurface formation.  Initially, steam is injected into the formation for a period of time by way of an injection well and a production well.  Thereafter, the wells are backflowed to produce fluids from the formation.          Production may be preceded by a shut-in period allowing the steam to soak and transfer heat to oil in the formation.          This cycle of steam injection followed by backflowing is designed to create voidage in the formation for the second stage of the process.  This voidage is needed to permit adequate oxygen injection for the second stage.  Thereafter, an oxygen-containing combustion-supporting gas is injected by way of the injection well into the top of the formation to form a fluid conductive path between injection and produc-tion wells.  The oxygen combustion-supporting gas must be injected into the top of the formation to accomplish the objectives of this invention.  Subsequently steam is injected into the formation, preferably near the bottom of the forma-tion.  Steam rises up and then steam and condensed water flow over the oil through the conductive path created in the in situ combustion stage of the process.  Heated oil adjacent the top of the formation is produced by steam drag into the producing well or wells.  The steam drag of the third stage of the process recovers much more oil than would be produced by conventional steam drive.

Abstract: PROCESS FOR MANUFACTURING CLAD ALUMINUM-LITHIUM ALLOYS          ABSTRACT OF THE INVENTION A metallurgical bond at the interface between an aluminum-lithium core alloy and a metallic liner is achieved by first forming a mechanical bond along the interface between the core and liner under moderated temperature and reduction conditions, and then heating the composite without simultaneous reduction to cause diffusion of the elements across the core-liner inter face.  The result is a metallurgical bond securing the layers together to form a composite which can be worked, shaped, and fabricated by normal reduction techniques into a full range of products without the discoloration and fouling problems otherwise typical of aluminum-lith-ium alloys.

Abstract: ABSTRACT OF THE DISCLOSURE      In a hay baler for producing rolled bales of the type having a shaping chamber in which the hay introduced in the form of a sheet is wound on itself around a horizontal axis (XX'), a tying mechanism has two distributors for ties which are mounted to swivel under the action of a control means to perform a reciprocating movement along the shaping chamber from a rest position near one end of the chamber to an end-of-tying position near the opposite end of the chamber.          The distributors are mounted to rotate around an axis (Y) fixed to one of the side walls of the baler while the control means is fixed to the other side wall.  An actuator with a reciprocating movement controlled by the control means first successively drives the distributors from the rest position to the end-of-tying position in the vicinity of which a severing means interrupts the ties, then returns the distributors to the rest position.

Abstract: DIMENSIONALLY STABLE THERMOPLASTIC TUBULAR ARTICLES For heat-setting tubular articles (such as can bodies) of an at least partly biaxially oriented crystallisable polymer, preferably a saturated linear polyester such as polyethylene terephthalate, e.g. for thermally processable food containers, a tube of the polymer is fitted over a mandre1 and clamped at its ends to the mandrel at a temperature below the glass transition temperature of the polymer. The tube is then heated, e.g. by inserting a heater into the interior of the mandrel, above the temperature to which it is to be heat-set (at least 60.degree.C above for PET) whereupon it shrinks into contact with the mandrel but is restrained from axial or further radial shrinkage. The tube and mandrel are cooled to below the heat-set temperature and the tube may then be cut into can body sections by knives engaging in circumferential grooves . Contact between the tube and mandrel is released, e.g. by forcing compressed air out through small holes in the mandrel surface to allow the tube and mandrel to be separated. Tubular bodies with one closed end can be heat-set on a mandrel with a correspondingly shaped end.

Abstract: ABSTRACT OF THE DISCLOSURE       A piston of a light alloy matrix material having a cavity for containing heat insulating air immediately below its head or a cavity for passing cooling oil inside the grooved   side wall is manufactured by preforming a precursory member having the shape of the cavity from an extractable material which remains in solid state at room temperature and is convertible into a fluid, gas or liquid when heated at a temperature below the melting point of the matrix metal.  The precursory member is disposed in place in a pressure casting mold having a cavity corresponding to the shape of the piston, and covered with a porous member stable to the molten matrix metal.  A head member of heat resisting metal material to constitute at least a portion of the piston head may be disposed on the mold cavity bottom. Molten matrix metal is then cast into the mold cavity and a pressure is applied thereto to form a piston-shaped casting having precursory member and porous member embedded therein. Finally the casting is heated at a sufficient temperature to gasify or liquefy the extractable material of the precursory member material into fluid, which is extracted from the casting, leaving a cavity at the location of the precursory member.  Alternatively, the precursory member may be formed from a composite material of a gasifiable material and a stable material whereby the cavity is given as a porous insert of the stable material which is left after the extraction of the gasifiable material by heating.

Abstract: ABSTRACT OF THE DISCLOSURE         A balanced type subscriber line interface circuit capable of being fabricated at least partly in a monolithic IC is described.  The battery feed circuit comprises three pairs of mirror circuits connected to each other so as to eliminate longitudinal noise and noise induced in the voltage source.          Overcurrent protection is achieved by varying the mirror ratio of current feeding mirror circuits when the subscriber line current exceeds a threshold value.  A 2- to 4-wire converter has its frequency characteristics compensated by feeding back a current with an impedance network composed of two impedance elements each having respectively an impedance N time as high as that of the load impedance and the termination impedance. The turn around signal in the output signal of the 4-wire system is canceled by mixing a signal opposite in phase to that of the 4-wire input signal.  The supervising circuit provides scan signals detecting the currents running through the subscriber line, and discriminating the states of the sub-scriber lines.  The circuit is provided with a ground separation circuit to separate the grounds of high voltage source and low voltage source.  The separation is done by feeding a current having a same amplitude but opposite phase to that of the signal current transferred from the receiving system to the sending system having a different ground.
