Abstract: TITLE:  COMBINATION HYDRAULICALLY SET HANGER             ASSEMBLY WITH EXPANSION JOINT                           ABSTRACT OF THE INVENTION The disclosure relates to an improved apparatus for ef-fecting the cementing of a liner at the bottom of a well bore. The liner sleeve assembly is inserted into the well bore on a hanger which is detachably connected to a running tool, which, in turn is connected to the work string by a torque transmitting expansion joint.  The running tool may be fluid pressure actuated to set the hanger.  In the event of failure of the fluid pressure setting operation, the hanger may be mechanically set by rotation of the work string transmitted to the running tool by the torque transmitting expansion joint.

Abstract: A B S T R A C T      A keyboard coding apparatus, said keyboard having a plurality of keys arranged according to a matrix of C columns and R rows, comprises a scanning interface inclu-ding a counter, a decoder and a multiplexer.  The scanning interface, in consequence of each pulse received from a microprocessor through an input lead, sends to the micro-processor on an output lead a logic signal indicative of the state of any selected one of the keys.  Whenever the microprocessor sends a pulse to the scanning interface, it increments by one the content of an internal register of its own and, before sending another pulse, processes the signal coming from the scanning interface.  If the logic level of such signal indicates a condition of actu-ated key, the microprocessor draws the character code rela-ted to the actuated key from a memory position whose address is latched into its internal register.  The keyboard coding apparatus, besides simplifying the keyboard interface unit, considerably reduces the number of connection leads between the microprocessor and the interface unit.

Abstract: Abstract An improved process for solvent extraction of organic matter from shale by two extraction steps in sequence. The extraction steps are:  (a) treating a kerogen-containing shale with a solvent system comprising a combination of water and an alcohol at a temperature of about 375°-425°C, and (b) treating the product of (a) with a solvent system comprising a combination of an alcohol and another organic solvent at an elevated temperature, but not above about 425°C.  The organic matter is recovered by separating the liquid which results from step (b) from the shale solids.

Abstract: OVERWRAP CASING AND METHOD OF APPLYING SAME           ABSTRACT OF THE DISCLOSURE         This relates to the encasing of shirred casing strands for the purpose of maintaining the shape thereof during soaking and subsequent to the soaking until such casing strands are applied to a stuffing horn.  Each casing strand is encased in an overwrap casing which is applied in tubular form and preferably is in the form of netting.  The overwrap casing is shaped at least at one end of the casing strand to define closure panels by twisting the overwrap casing at that end of the associated casing strand so as to reduce the diameter of the overwrap casing and to facilitate the reverse folding of the over-wrap casing.  The opposite end of the overwrap casing may be closed in a similar manner or by a simple gathering of the material of the overwrap casing and the applica-tion of a conventional clip.  This abstract forms no part of the specification of this application and is not to be construed as limiting the claims of the application.

Abstract: ZIRCONIA INDUCTION FURNACE     Abstract A high frequency induction furnace for reflowing a portion of a lightguide preform in order to draw a fiber therefrom.  The furnace has a centrally located tubular susceptor therein having a thin coating of the preform material (e.g., silica) on at least a portion of the inside surface thereof.  A cylinder is positioned in concentric, spaced relation about the susceptor and is surrounded by an insulating grain.  A high frequency coil is energized to couple its electromagnetic field to the susceptor to heat and reflow a portion of the preform in order to draw the fiber therefrom.  The thin coating prevents contaminating particulates from migrating from small cracks in the inside surface of the susceptor onto the preform while the cylinder prevents small particulate emanating from the insulating grain from being drawn through larger cracks in the susceptor and onto the preform and/or the fiber 52.

Abstract: Abstract CONTAMINATION LEVEL INDICATOR Apparatus for providing an indication of the level of contaminant in a fluid includes a pervious barrier (12) disposed across a fluid path (11) so that the barrier (12) will be progressively blocked by contaminant in the fluid.  Monitoring means responsive to the rate of blocking of the barrier provides an indication of the level of contaminant in the fluid. The monitoring means may be means for sensing  measurements representing the rate at which the pressure of the fluid upstream of the barrier (12) rises.  Alternatively the monitoring means senses measurements representing the rate at which the flow rate of fluid through the barrier (12) falls. The provision of an indication conveniently completes a measurement cycle and there is means for renewing the barrier, either by back-flushing the barrier(12) or alternatively by exchanging one barrier for another.
