Patent CA-1091374-A (CA)
Inventor: HEFFERNAN STUART D
IPC: H04M1/72
Filed: 1978-05-19
Granted: 1980-12-09
Abstract: ABSTRACT       This circuit utilizes the customer's own tip and ring lines to allow the customer selectively to transfer incoming calls from a primary equipment location (e.g. a primary telephone) to an auxiliary equipment location (e.g. answering bureau).  A manually operable, double throw switch on the customer's premises is connected to the loop of the customer's primary phone, and in one position connects the primary loop directly to the associated telephone company's COE (central office equipment).  In its other position the switch allows current leakage in at least part of the primary loop, and a sensing network effects energization of a transfer relay if the leakage current is sufficient and flows in the proper direction.  The energized relay transfers the COE to the customer's auxiliary equipment location.  Slave circuits controlled by the transfer relay may effect transfer on a multitude of central office lines.  The transfer on each loop is only acti-vated when that loop is idle.

Title: Large locking snubber

Abstract: LARGE LOCKING SNUBBER            Abstract of the Disclosure A telescoping, shock absorbing strut capable of supporting extremely large loads in which an overhauling lead screw drives a tubular inertia member for sensing a motion threshold.          Nonoverhauling threaded members are synchronized and do not contact when rotated at the proper speed by the overhauling lead screw.  When the telescoping forces induce motion in the strut which is above the motion threshold, however, the nonoverhauling screw threads engage to support substantial loads in a locked strut configuration.  By driving the tubular inertia member with a thin walled tubular driving element, the tubular inertia member in extremely large struts of this type may be maintained relatively small in size, so that the motion threshold sensing mechanism can also be maintained relatively small in size.  The desynchronization of the threads may be caused by either a unique axial spring and ball detent combination, or a unique torque rod interconnected between the thin walled tubular driving member and the overhauling lead screw.

Abstract: ABSTRACT OF THE DISCLOSURE A foam extrusion apparatus and method employs an extruder on an upper level extruding foamable extrudate into the upper end of a large elongated barometric leg which extends at a relatively shallow angle into a pool of water at a lower level. A conveyor in the barometric leg extends through a large radius in the pool to guide the extrudate from the pool for further processing. The leg is in the form of an elongated pipeline fabricated from sections and supported on an inclined ramp. Some of the sections are securely anchored to the ramp to resist axial forces when the leg is evacuated. The sections may be reinforced concrete or fabricated reinforced steel of a variety of sectional shapes. Each section is sealed end-to-end so that a vacuum within the leg will draw water from the pool into the leg leaving a vacuum chamber at the upper end of the leg in which the extrudate expands. The leg may be provided with a number of windows for visual access and the two levels may be the floors of two horizontally and vertically separated plants. The lower end of the leg may be provided with a baffle where it enters the pool.

Abstract: ABSTRACT OF THE DISCLOSURE           Disclosed is an improved method of recovering a first said from an aqueous solution containing the first salt and a second salt, the first salt having a solubility increasing more with increasing tempera-tures than the solubility of the second salt.  The solution is passed through an evaporation zone thereby concentrating the solution with respect to the first salt and precipitating the second salt, which precipitated salt is withdrawn from the evaporation zone in a slurry.  In the improved method the withdrawn second salt slurry is introduced into the upper level of an elutriation column wherein the precipitated second salt slurry mother liquor is displaced with a relatively dilute first salt aqueous solution introduced into a lower level of the column, while the second salt crystals are removed from the lower level of the column in a relatively dilute first salt aqueous solution slurry ant while the relatively concentrated first salt mother liquor displaced from the slurry is removed from the upper level of the column for recycle back to the evaporation zone.

Abstract: Abstract of the Disclosure A method for the preparation of vanillin from lignosulphonate is disclosed herein. The lignosulphonate used as raw material is ob-tained in connection with sulphite pulping. For the preparation of vanillin only such a portion of said lignosulphonate is used the molecular weight of which exceeds by more than 50 per cent the value 5000. The vanillin is prepared from said raw material in a manner known per se by oxidation and alcohol extractions. The vanillin ob-tained is then reacted with sulphur dioxide in order to give the bisulphite complex of vanillin. The bisulphite complex formed is decomposed by adding an alakali and extracted during the decomposi-tion or immediately thereupon with an organic solvent. The solu-tion is washed with slighty alkaline water and the organic solvent is thereafter evaporated in a low vacuum to get crude vanillin.

Abstract: METHOD FOR FABRICATING SELF-ALIGNED HIGH RESOLUTION NON PLANAR DEVICES EMPLOYING      LOW RESOLUTION REGISTRATION                         Abstract A method is disclosed for fabricating structures having electrically conductive regions such as high resolution semiconductor device and circuit designs which require only low resolution alignment steps during fabrication.  The method is used to fabri-cate metal semiconductor field effect transistors (MESFET) and metal oxide semiconductor field effect transistors (MOSFET) devices and incorporates the following features.  A device with very small (i.e. submicron) dimensions is positioned in a relatively large device well such that the exact position of the device in its well is not critical.  Isolation and interconnection of devices in different wells is achieved by standard masking and alignment techniques with a resolution corresponding to the larger dimensions of the device wells.  All high resolution features of the device are contained in a single masking level, however, to separate and insulate different elements of the device at such small dimensions different height levels are used in the device so that one masking step can produce zero lateral spacing between the different device elements.  The disclosure provides examples of the present method applied to the fabrication of a MESFET device and a MOSFET device and to the isola-tion and interconnection of single devices into large circuits on a semiconductor chip.

Abstract: "RECOVERY OF TITANIUM METAL VALUES"                     ABSTRACT           Titanium metal values may be recovered from iron and titanium bearing sources such as an ilmenite ore by subjecting the source to a reductive roast after having crushed the source to a desired particle size.  The reduced source is then leached by treatment with a halogen-containing compound to form soluble titanium halides and iron halides. Thereafter, the soluble titanium halide is precipitated as titanium di-oxide by treatment with an iron oxide such as ferric oxide.  The desired titanium dioxide or rutile may be recovered without an appreciable loss by effecting the leach step of the process in such a manner so that the solution potential is not greater than about +150 millivolts.
