Patent CA-1156137-A (CA)
Inventor: HOLMES ARTHUR S
IPC: F25J3/02

Abstract: ABSTRACT         The invention is concerned with a distillative method of separating in a distillation apparatus a mixture containing carbon dioxide and a light hydrocarbon into a carbon dioxide rich overhead fraction and a light hydro-carbon rich fraction, the conditions of distillation being such that the carbon dioxide and light hydrocarbon are liable to form an azeotrope therebetween.  The method of the invention is characterized in that an additional liquid component is added to the mixture under distillation at a point above the feed to the distillation apparatus, which liquid component significantly alters the relative volatility between the carbon dioxide and the light hydrocarbon so that the volatility of the carbon dioxide is maintained above that of the light hydrocarbon at all points at and below  the point of introduction of the liquid component, whereby the concen-tration of carbon dioxide in the overhead fraction exceeds the azeotropic composition.  The invention allows a more complete separation to be achieved.

Abstract: A B S T R A C T           A process for the continuous preparation of a slurry of calcium hypochlorite wherein a solution of sodium hydroxide is fed to one end of an elongated tubular reaction and a calcium hydroxide slurry and chlorine are introduced through a number of injection sites along the length of the reactor.  The redox potential of the reaction mixture at any injection site must not be inferior to that at the immediately preceding site and must be in the range 900 to 950 mV at the exit end of the reactor. The process permits easy control of the reaction temperature and of the viscosity of the reaction mixture.

Abstract: ABSTRACT OF THE DISCLOSURE      A progressive multi-focal lens is provided of the type having a distant viewing zone, a near viewing zone, and a progressive zone therebetween.  The surface refractive power increases vertically from an upper portion of the lens to a lower portion as the line of sight scans from a distant view to a near view.  Side zones are provided beside the progressive and near viewing zones.  The side zones are spheric surfaces, with a dioptric refractive power in accordance with one embodi-ment being the arithmetic mean value of the refractive power of the near and distant viewing zones. This eliminates astigmatism problems in the side areas and permits normal side sight.

Abstract: "RECOVERY OF METAL VALUES FROM A METAL BEARING SOURCE"                                ABSTRACT           Metal values may be recovered from metal bearing sources which contain at least two metals, at least one of which is in the form of a sulfide, by treating the aforesaid source with an oxidant at an elevated temperature in the range of from about 600° to about 1500°C and in the presence of an added promoter comprising a sulfur-containing compound. The treatment will convert at least one metal value to an oxide and at least one metal value is converted to the elemental state which contains a relatively minor amount of a subsulfide.  The addition of the sulfur-containing compound will result in an increase in the particle size of the elemental metal, thus permitting the recovery of said metal more readily.

Abstract: ABSTRACT      A cordfree instrument for full-duplex voice and/or data communication via a diffuse infrared radiation communication link with a base station.  Private multi-channel operation is afforded by diffuse infrared radi-ation carrier transmission in which a sub-carrier, fre-quency-modulated by voice or data signals, amplitude-modulates the intensity of infrared radiation from light-emitting diodes.  The instrument may be a headset or hand-held voice communication instrument, and/or a port-able data terminal.  When the instrument is functioning as a voice communication instrument, the infrared transmis-sion carrier may be voice actuated for reduced power consumption. the apparatus may be used as a telephone subscriber instrument, with the base station interface to a telephone line.  When in use as a telephone subscriber instrument, the cordfree instrument and base station provide remote hookswitch control.

Abstract: ABSTRACT OF THE DISCLOSURE    A joystick controller 10 for remotely controlling hydraulic directional control valve 82 and also for control-ling a solenoid actuated pressure build-up valve 90 is disclosed.  A light-emitting diode 19 is carried in and by a handle 13 of the joystick controller 10.  A photosensitive transistor 31 receives the light emitted from the light-emitting diode 19.   When the handle 13 moves off of a neutral position, a receptacle 28 blocks the light from the photo-transister 31.  In one embodiment, a fiber optic light conductor 20 extends from the light-emitting diode 19 toward the photo-transistor 31.   The photo-transister 31 then actuates a relay switch which sends a control signal to a solenoid  actuated pressure build-up valve 90, thereby providing a ready means for effectuating both the control of the hydraulic directional control valve 82 and the pressure build-up valve solenoid 90 with one controller 10.

Abstract: Method For Making Low Barrier Schottky Devices By The Electron Beam Evaporation Of Reactive Metals Abstract A method for making low barrier Schottky de-vices by the electron beam evaporation of a reactive metal such as tantalum, titanium, hafnium, tungsten, molybdenum, and niobium which is selectively de-posited at a semiconductor surface such as n-type silicon using a photresist mask. The method includes a series of steps during the deposition of the barrier metal for degassing the semiconductor substrate, photoresist mask, reactive metal charge and deposition chamber. More particularly, the method includes steps for preliminarily degassing the substrate, mask and surrounding chamber by infra red heating under vacuum followed by steps for preliminarily degassing the charge and surrounding chamber, while the substrate and mask are shielded by electron beam heating the charge while under vacuum. Thereafter, and prior to deposition, the substrate and mask are finally degassed by irradi-ation with X-rays produced by electron beam heating the charge to a temperature below evaporation for a predetermined time under vacuum. Upon further heating of the charge, the barrier metal is evapo-rated and deposited at the semiconductor substrate surface.
