Granted: 1991-01-15
Abstract: ABSTRACT: Crucible for epitaxy from the liquid phase of semi-conductor layers having a controlled composition.         The invention relates to a crucible for growing epitaxial layers having a chemical composition formed by several chemical elements, of which at least one is volatile, by the method of epitaxy from the liquid phase, comprising an elongate support (72) on which a movable part (73) slides longitudinally, the support comprising at least one recess for accommodating a substrate (76) on which at least one epitaxial layer is to be deposited, the movable part (73) comprising at least one cavity (77) receiving a mother source (79) formed by initial material for epitaxy, the cavity having on the surface adjoining the support a lower opening whose dimensions correspond to the dimensions of the substrates (76) present therein, and at least one receptacle (80) accommodating  a source for each volatile element of the chemical composition. It is characterized in that at least one of the cavities of the movable part (77), for which a substrate (76) is present before the lower opening, has at least one upper opening formed solely by a calibra-ted conduit (78) each of which is connected to the receptacle (80) accommodating a source of each volatile element, each calibrated conduit (78) controlling the supply of the said element to the mother source by the surface of the mother source which is not in contact with the epitaxial layer. The calibrated conduit (78) maintains a substantially constant composition for the mother source.        The invention is used in-growing epitaxial semiconductor layers of semiconductor compounds, especially of Hg1-xCdxTe. Application: growth of epitaxial layers. Reference: Fig. 1.

Title: Air pressure measurement element and system incorporating same
Inventor: TADDEO JOHN

Granted: 1991-04-30
Abstract: Title:  Air Pressure Measurement Element and System Incorporating Same Inventor:  John Taddeo Abstract Of The Disclosure A unitary element for use in measuring the total and static pressure of a gas flowing through a duct is disclosed in a preferred embodiment.  The element is elongated and hollow, having a continuous, impermeable wall dividing the interior into total and static pressure chambers.  In cross section, the element is of aerodynamic or airfoil shape, having a curved forward edge and converging toward the trailing edge adjacent which the outer surfaces are parallel for a short distance.  Spaced openings along the forward edge and the upper and lower portions of the rearwardly converging wall portions communicate with the total and static pressure chambers, respectively.  Separate manifolds communicate with the total and static pressure chambers of a plurality of such members arranged across an air flow duct to obtain average pressure readings across the cross section of the duct.  Configuration of the measuring element and the position of the static pressure openings highly influence accuracy of the signals and permit velocity pressure readings which are amplified, yet linear over a wide range, with respect to actual velocity pressure within the duct.

Title: Inclination measuring device
Inventor: RYAN PAUL T
IPC: A61K31/22
Filed: 1987-01-22
Granted: 1991-11-12
Abstract: ABSTRACT    A sensor for an inclination measuring device is disclosed which comprises a capsule 3 part-filled with a conductive liquid.  First to fourth electrodes A-D are disposed within the capsule in contact with the liquid.          An electrical signal is applied between electrodes C, D and one then the other of electrodes A, B, to derive a signal indicative of the degree of immersion of the electrode A, and then the electrode B within the liquid.  The ratio of these signals is related to the angle of inclination of the capsule about the reference axis O and relative to a first reference angle defined at the gap between the electrodes A, B.  A similar gap, defining a second reference angle is disposed between electrodes C, D, perpendicular to the gap between electrodes A, B, and by reconfiguring the electrodes A-D, to measure the degree of immersion of electrodes C and D, the sensor is able to sense any angle of inclination about the reference axis.

Title: Slip gripping mechanism
Inventor: BAUGH JOHN L
IPC: F16D1/02
Filed: 1987-02-03
Granted: 1991-07-02
Abstract: ABSTRACT      A slip gripping mechanism is shown for supporting a string of cylindrical conduit within the interior bore of a  circumscribing  conduit.    An  elongate  body  has  a plurality  of  spaced  longitudinal  slots  at  one  end. Vertically shiftable slips are carried in the slots by side edges which engage mating profiles formed in the slots.

Title: Tag for use with personnel monitoring system
Inventor: PAULEY JAMES D
IPC: G08B25/00
Filed: 1987-04-14
Granted: 1992-04-28
Abstract: Abstract of the Disclosure A tag for use with an individual monitoring system. The tag is worn by an individual being  monitored,  preferrably  on the  ankle  or leg where it can be concealed by the clothing of the individual. The tag is fully  self  contained  and  sealed. The  ciruits of the tag periodically generate an identification signal that includes an identification code. The identification signal modulates a stable RF  signal  that  is  transmitted  in bursts  of  data  words  to  a receiver associated with a field monitoring device (FMD) located at the monitoring location.  In turn, the FMD  may  randomly  establish  communication  with  a central  processing  unit (CPU) located at a central monitoring location. Other information is included in  the  identification code of the tag, such as information indicating that an attempt has been  made to remove the tag from the individual.  The tag is held in place near the skin of it's wearer by  a  conductive strap   that  wraps  around  the  leg  or  other  limb  of  the individual. Two capacitive electrodes, one of which is realized with  the  conductive  strap,  function  as  the  plates  of  a capacitor,  with  the  body  flesh  serving  as  the dielectric material therebetween.  By  monitoring  an  alternating  signal coupled   from   one  capacitive  electrode  to  the  other,  a determination can be made as to whether the  tag  has  remained near  the body flesh. Further, because the strap is conductive, a signal can be passed therethrough and a determination can  be made as to whether the strap has been broken.

Abstract: ABSTRACT            SOLID-STATE TRIP UNIT OF AN ELECTRICAL CIRCUIT BREAKER WITH          CONTACT WEAR INDICATOR            A digital solid-state trip unit of an electrical circuit breaker is equipped with an electrical contact wear indicator enabling the degree of wear of these contacts to be known. Each time the circuit breaker performs a break, the microprocessor determines a contact wear value, in terms of the maximum valve of the current broken. The correspondence between the wear value and the current broken is stored in a ROM memory and the successive wear values are added in a NOVRAM memory whose contents are representative of the degree of contact wear. These contents can be displayed to indicate to the user that the condition of the contacts has to be checked.
