Title: Extraction and purification of titanium products from titanium bearing minerals

Abstract: Titaniferous solid containing titanium (IV) oxide, for example ilmenite, is reacted with silicon tetrafluoride gas at 800°C or more and at a pressure of at least 1 atmosphere to produce titanium tetrafluoride vapour and silica. The vapour is rapidly removed from the reaction zone, preferably by rapid cooling to solid titanium tetrafluoride, at a sufficient distance from the reaction zone so as not to quench the reaction. The titanium tetrafluoride may be hydrolysed to produce titanium dioxide and hydrogen fluoride which is combined with silica to regenerate silicon tetrafluoride. It is preferred to pretreat the titaniferous solid by grinding and then roasting at 700°C to 750°C in air. Products of the reaction may be separated and purified by condensation and resublimation.

Abstract: FILTER CONTACT                     ABSTRACT OF THE DISCLOSURE             A  contact  assembly  for  installation  in  an electrical  connector,  provides  effective  electromagnetic filtering  in  a  simple,  compact,  and rugged construction that facilitates in-field replacement of a damaged contact assembly.  The contact assembly includes a signal conductor, a diode for diverting high voltages on the signal conductor to  ground, and a "pi"  filter for filtering out unwanted frequencies.  The "pi"  filter  includes  a  ferrite  bead inductor  coupled  to  the  signal  conductor  and  a  first capacitor  coupling  a location of the signal conductor on a first side of the inductor to ground. The other capacitor of  the  "pi"  filter is formed by the capacitance of the diode, with the diode connected to a signal conductor location  on  a  second  side  of the inductor, and with the capacitance  of  the  diode  similar or equal to that of the first  capacitor.  The  diode  is  mounted in a notch of the signal  conductor,  the   ferrite  bead  inductor  lies immediately  forward of the notch, and the first capacitor lies  immediately  forward  of  the  ferrite  bead.  A ground conductor has a sleeve portion that immediately surrounds both the first capacitor and the ferrite bead, and has a finger  contacting the diode.  Solder holds the finger of the ground  conductor  in  place  both mechanically  and electrically.  A quantity of epoxy fills the remaining notch area  and  forms  the middle  of  the  assembly  with a cylindrical  periphery  to  facilitate insertion and removal from a long narrow hole in the connector.

Granted: 1995-08-01
Abstract: An insulating electrical feed-through connector extending through a wall of aluminium is obtained by using a sintered sleeve comprising phosphate glass in which a conductive pin is inserted. The sleeve is raised to a firing temperature in excess of the dilatometric softening temperature of the vitreous material in the presence of a first effective quantity of alumina between the sleeve and the wall and of a second effective quantity of nickel oxide between the sleeve and the pin, which makes it possible to achieve a simultaneous and direct hermetic sealing of the sleeve to the wall and of the pin to the sleeve.

Title: Method for determining induced fracture azimuth in formations surrounding a cased well
Inventor: MEDLIN WILLIAM LOUIS
IPC: G01V1/44
Filed: 1990-02-02
Granted: 1999-08-03
Abstract: An acoustic logging tool traverses a fluid-filled cased well with an asymmetric acoustic energy transducer.  Pressure waves created in the well fluid by the transducer generate asymmetric tube waves in the well casing.  At least one spaced-apart transducer receives these asymmetric tube waves after they have traveled directly to the receiver through the well casing.  Changes in tube wave amplitude as detected by the receiver are used to identify the azimuth and height of any fracture interval in the formation behind the well casing.

Title: Load cell mounting for rotational control
Inventor: MILLS NIGEL G
IPC: G01G21/23
Filed: 1990-07-11
Granted: 1995-10-31
Abstract: Load cells incorporating rocker pin configured columnar central structures within a weighing system have the attribute of self-erecting upon being displaced from a vertical orientation due to dynamic transverse loading effects, as may be occasioned by vehicle movements onto a scale. The resultant transient vector forces thus developed have been observed to cause a rotational phenomenon in the rocker pin configured cells which causes unacceptable damage to the instrumentation control communication components of the load cell system. A mounting technique for such load cells is developed wherein only these rotation inducing forces are restrained, while the vertical force vectors representing valid load data are maintained in an unrestricted or uncompromised manner. In one aspect of the invention, a hexagonal form of mounting between a rocker pin neck-contact surface region and a corresponding receiver cavity achieves a fully pivoting and freely abutting contact geometry while effecting the noted restriction of rotation. In another aspect, a resilient device such as spring is loaded during restricted rotational movement of the load cell and released at the termination of the transient rotational forces to return the load cells to their initial orientation while the load cells remain under load induced compression.

Abstract: Abstract of the Disclosure:      A microwave resonator includes a ground conductor formed on an under surface of a dielectric layer and a signal conductor formed on an upper surface of the dielectric layer separately so that the signal and ground conductors cooperate to form a microstrip line. The signal conductor has a launching pad portion for receiving a signal, and a resonating conductor portion forming an inductor. The resonating conductor portion is formed separated from the launching pad portion so that a gap between the launching pad portion and the resonating conductor portion forms a capacitor. Thus, the inductor formed by the resonating conductor portion of the signal conductor and the capacitor formed by the gap between the launching pad portion and the resonating conductor portion form a resonator circuit. The resonating conductor portion of the signal conductor and a portion of the ground conductor positionally corresponding to the resonating conductor portion of the signal conductor are formed of a compound oxide superconductor material, and the launching pad portion of the signal conductor and the remaining portion of the ground conductor are formed of a metal which is of a normal conductor.
