Title: Personnel evacuation apparatus for an offshore platform
Inventor: HUNTER ANDREW F
IPC: E02B17/00
Filed: 1987-02-10
Granted: 1991-04-09
Abstract: Case No.:  7063 Abstract of the Disclosure Personnel  evacuation  apparatus  for  use  with  an offshore  platform.   A  launching  ramp  that  is  mounted  to the platform by a gimbal is stowed in a vertical position with  a  survival  vessel  secured  in the  entry  end of  the ramp.   A  release  mechanism  activatable  from  the  deck  of the platform enables flotation members secured to the exit end of  the  ramp,  to  pivot  the  ramp about  the gimbal to its  deployed  position.   The  gimbal  further  permits  the ramp to maintain a usable orientation inspite of inclination of the deck of  the platform by 25° due to pitch,  roll or yaw.   The exit end will pivot under wave action so as  to gravity launch the survival vessel downwind and, upon release of  the boat securement,  carry the vessel safely away from the platform.

Title: Hydrometallurgical arsenopyrite process
Inventor: RAUDSEPP REIN
IPC: C22B3/06
Filed: 1987-05-26
Granted: 1992-10-27
Abstract: IMPROVED HYDROMETALLURGICAL ARSENOPYRITE PROCESS      ABSTRACT         This invention is directed to an improved process for leach treating gold and silver bearing pyritic and arsenopyritic concentrates and ores.  More particularly, the improved process avoids the necessity of adding recycled neutralized solution to the leach solution, thereby alleviating difficulties in maintain-ing acid levels in the leach solution, and provides for bleeding solutions containing dissolved arsenic, iron and sulphate from the process without the loss of oxidized nitrogen species.  The process for recovering valuable metals from pyritic and arsenopyritic concen-trates and ores involves decomposing the arsenopyrite or pyrite concentrates and ores in acidic solution in a common volume space which contains a gas phase and a liquid slurry (which comprises a liquid phase and a solid phase) through the action of higher valence oxidized nitrogen species in which the nitrogen has a valence of at least plus 3.  The active oxidized nitro-gen species are regenerated in the same common volume space by an oxygen containing gas.  The concentrate or ore is introduced into a denitrating step.  The liquid and solid products of the denitrating step are subjected to a solid-liquid separation, after which the solids from the separation step are transported to a leaching vessel where the solids are treated with oxygen and nitric oxide replaced from the denitrating step.

Abstract: ABSTRACT OF THE DISCLOSURE      A method and device for determining the presence of an analyte in a sample suspected of containing the analyte is disclosed.  The method involves contacting a test solution containing the sample, an antibody for the analyte, and a conjugate of the analyte and a label with a contact portion of a piece of bibulous material capable of being traversed in at least one direction by the test solution through capillary action.  The bibulous material contains a first receptor capable of binding to said conjugate.  The first receptor is non-diffusively bound to a situs on the bibulous material separate from the contact portion.  The bibulous material further contains a second receptor capable of binding the antibody to the analyte between the situs and the contact portion.  The second receptor is non-diffusively bound to the bibulous material.  At least a portion of the test solution is allowed to traverse the bibulous material by capillary action and thereby contact the situs.  The situs is examined for the presence of the conjugate.  To this end, the situs can be exposed to a signal producing means capable of interacting with the label to produce a signal in relation to the amount of analyte in the test solution.  The signal produced at the situs is then detected.

Abstract: A rotatable shaft/thrust plate combination is disposed within a sleeve to form a first clearance space between the shaft and the sleeve and a second clearance space between the thrust plate and the sleeve.  The external faces of the thrust plate are exposed to air. The clearance spaces are filled with a liquid lubricant and the sleeve includes pressure equalization ports connecting the first and second clearance spaces. Surface tension dynamic seals are provided between axially extending surfaces of the thrust plate and sleeve.  The equalization ports balance the hydrodynamic pressures in the lubricant to prevent the lubricant being pumped through one of the dynamic seals.  The resulting bearing provides high precision with low repetitive and nonrepetitive runouts.  The bearing provides hydrodynamic support of both radial and axial loads and the bearing seal is relatively insensitive to orientation of the spindle and minimizes the generation of debris and contaminating particles.
