Patent CA-2067420-A1 (CA)
Inventor: HART JUDY L
IPC: F16G15/06
Filed: 1992-04-28
Abstract: Abstract of the Disclosure A closure pin extends through aligned openings in first and second spaced apart eyes at the open end of a substantially U-shaped clevis.  one end of the closure pin is threaded and mates with threads in the opening in the second eye.   The closure pin includes a head portion and a radial flange at its opposite end, and it carries a releasable lock member.  The releasable lock member includes a pair of detents which are positioned in radial slots in the flange.  A spring biases the lock member into a position in which the detents extend axially beyond the radial flange towards the threaded end of the pin. A plurality of lock ramps are provided on the outer face of the first eye.  The ramps are spaced circumferentially apart.  Each ramp includes a first end which is substantially flush with the outer face, a second end spaced circumferentially from the first end and axially outwardly from said face, and inclined surface extending from the first end to the second end, and a second surface at the second end extending out from said outer face.   As the closure pin is rotated to connect it to the clevis, the detents contact and move up the inclined surfaces of the ramps and by such contact are moved against the force of biasing spring into the slots, allowing the closure pin to be rotated.  When the closure pin is connected to the clevis, an unwanted reverse rotation of the closure pin is blocked by contact between the detents and the end surfaces of the ramps. The closure pin can be easily disconnected from the clevis by a user retracting the lock member, to retract the detents into the  slots of the annular flange,  while at the same time rotating the closure pin in a reverse direction.

Title: Production of the molecular sieve regeneration stream from the high pressure column to reduce the feed air pressure in air separation plants
Inventor: XU JIANGUO
IPC: F25J3/04
Filed: 1992-05-07
Abstract: ABSTRACT The current invention relates to the production of a molecular sieve (or other adsorbents) regeneration waste nitrogen stream (M/S regeneration stream) from the high pressure column of a double column cryogenic air separation unit, which lowers the operating pressure of the low pressure column, which in turn lowers the discharge pressure of the main air compressor.  As compared to conventional air separation plants, wherein typically a nitrogen product stream is produced from the low pressure column so that the produced nitrogen product stream can be used as the M/S regeneration stream, the present invention constitutes a significant saving in energy consumption.

Title: Procedure for the inversion of the sterochemistry at c13 of avermectin aglycone compounds
Inventor: JONES TODD K
IPC: A61P33/00
Filed: 1992-05-11
Abstract: TITLE OF THE INVENTION PROCEDURE FOR THE INVERSION OF THE STEREOCHEMISTRY AT     ABSTRACT OF THE DISCLOSURE         The natural stereochemistry at the 13-position of avermectin aglycones, normally .alpha.-oriented or below the plane of the molecule, is inverted or epimerized into the .beta.-position.  The procedure starts with the avermectin aglycone compounds where the 13.alpha.-hydroxy group is substituted with a leaving group.  Treatment of the substituted compound with tetra alkyl ammonium nitrate displaces the leaving group, substitutes a nitrate ester or a nitrooxy group, for the hydroxy and inverts the 13-stereochemistry to .beta..  Reduction of the nitrooxy group returns the 13-hydroxy group and retains the 13-.beta. configuration.  The intermediate 13-nitrooxy compounds are themselves potent anti-parasitic agents.

Abstract: An operational transconductance amplifier (OTA) including a differential amplifier (M1/3) with a differential pair (M1/2) connected (VS) to a common current source (M3), and a control circuit (A, R1/2, M8/11) for obtaining a linear input volatge versus output current characteristic by maintaining the transconductance (gm) independent of the differential (VG2-VG1) and of the common mode (VG2+VG1) input voltages. The control circuit includes a negative feedback circuit with a comparator or operational amplifier (A) whose inputs are connected to the above connection point (VS) and to a reference terminal (Vref) whose voltage follows that of the differential inputs (VG1/2), the output of the comparator (A) controlling the current source (M3). The slope of the linear characteristic can also be modified by changing the voltage at the reference terminal (Vref) via an external input voltage terminal (VC). An additional current mirror circuit (M4/7), also controlled by the control circuit, is provided for suppressing the common mode output current in the differential pair (M1/2), this current being generated by the action of the control circuit on the current source (M3). <IMAGE>

Filed: 1992-10-15
Abstract: METHOD AND APPARATUS FOR DYNAMIC PRECOMPENSATION OF     SOLAR WING STEPPING MOTIONS OF A SATELLITE                 ABSTRACT OF THE DISCLOSURE           This invention discloses a method for compensating for the disturbance torque on an orbiting satellite (10) caused by the slewing motion applied to the solar wings (16,17) of the satellite (10) to track the sun.  The acceleration signals applied to the solar wings (16,17) in order to slew the wings are multiplied by an estimated inertia of the solar wings (16,17) to derive a control torque opposite to the disturbance torque applied to the satellite (10) by the slewing of the solar wings (16,17).  The estimated control torque is added to the control torques from other disturbances.  The added control torque is then applied to an actuation device (46) in order to actuate the satellite (10) into a desirable attitude.

Filed: 1992-12-23
Abstract: ABSTRACT OF THE DISCLOSURE    In a gas turbine arrangement having a plurality of independent pressure stages, with or without an integrated steam process, which is extended by an air cell cavern, ammonia is injected into the waste gases downstream of the first turbine and the first heat generator and upstream of a second heat generator.  The location of this injection ensures that the so-called selective nitrogen conversion becomes effective when a temperature window of 800 - 900 degrees Celsius is present.  By means of a purposeful, caloric preparation of the hot gases and appropriate design of the high-pressure turbine, the temperature window is made available at which NOx emissions can be minimized by means of injecting ammonia.
