Abstract: TITLE:   FLOW LINE MONITOR PILOT VALVE ASSEMBLY     ABSTRACT OF THE DISCLOSURE    A control fluid valve assembly is provided which is respond-able to a pressure monitored fluid.  The assembly preferably comprises first and second valve seats within a housing.  a spool element is shuttleable within the housing near the valve seat by either manual or mechanical manipulation to first and second positions and is responsive to pressure variation within the monitored fluid to shuttle it to a second position.  Balls are contained in first and second valve head groups and are carryable by the spool element, the balls being selectively sealingly en-gagable onto and wipable off of the valve seat means to control fluid flow of the control fluid within the assembly in response to the pressure monitored fluid.  A plurality of seals are defined between the housing and the spool means to prevent fluid communi-cation therebetween and to define flow passageways across the spool.  The spool is shiftable to each of first and second posi-tions and when in one of the positions pressure is substantially equalized within the flow passageways and the spool is statically stabilized.  When the spool is shiftable to the other position, pressure differential defined across one of the seals urges and holds the spool in this second position.  A control shaft is provided which is selectively communicable to the spool for shuttling the spool in one direction to one position.  Piston means are provided which are responsive to predetermined increase and/or decrease in pressure of the monitored fluid for shifting the shaft to shuttle the spool.  The apparatus may be selectively calibrated to respond to at least one of high and low pressure tolerance to cause shuttling of the spool to manipulate the balls with respect to the seats to vary the flow passageways within the valve and to selectively open and close, for example) a sub-surface safety valve within a subterranean oil or gas well.

Abstract: Case 2550 AMORTISSEUR WINDING PROTECTION SYSTEM               ABSTRACT OF THE DISCLOSURE   This invention relates to a system for protecting an amortisseur winding during the starting of a synchronous motor.  The system compares the actual slip frequency of the accelerating motor with predetermined slip frequencies.  These predetermined slip frequencies are each associated with a timer which measures successive time segments.  Each timer is stopped when the actual slip frequency, which decreases as rotor speed increases, is less than the associated predetermined slip frequency. When the timer is stopped a successive timer is started. In this manner the acceleration of the motor is broken up into time segments.  The initial timer is started when the motor starts.  The final timer is stopped when the rotor field current is applied to bring the motor into synchronism.  Should any timer be permitted to have its timed segment expire before being stopped, the motor is shut down.  There is also provided a thermal memory which receives information from the expired timer as to its associated slip frequency.  This information is used to inhibit the motor from being restarted until the amortisseur winding has cooled.  Previous systems were straight timing functions which crudely approximated the motor's acceleration.  The present invention provides a system that more closely approximates the motor's non-linear acceleration characteristic.

Abstract: Abstract of the Disclosure A heavy submersible objects is deployed from or retrieved to  a floating vessel in rough water.  The connection or release point is sufficiently far below the water surface that surface waves have little if any effect on the object. Deployment and retrieval are  made to an arm which depends from the vessel and which has a variable stiffness connec-tion, ranging from free-swinging to rigid, to the vessel. Deployment and retrieval are made with the arm free-swinging from the vessel so the arm has no motion due to pitch or roll of the vessel.  In retrieval, the connection is progressively stiffened to rigid after the object has been connected to the arm, and the arm is then raised with the retrieved object.

Title: Packing containers of laminated material

Filed: 1979-06-14
Granted: 1982-06-08
Abstract: ABSTRACT          A packing container e.g. for sterile milk is manu-factured from laminated material which is folded and sealed to the desired container shape. In the seal cut surfaces facing towards the inside will occur which have to be sealed so as to prevent the central paper layer of the material from absorbing some of the contents. Usually this is done by means of a strip of a plastic material which is impermeable to liquid. When the packing material is steri-lized and exposed to high temperatures these strips are often damaged, because the moisture present in the paper layer of the laminate is converted into vapour and pene-trates the strip softened by the heat. In accordance with the invention the seal is now ventilated with the help of ducts extending through the seal in such a manner that the vapour can escape to the surrounding air without affecting the sealing strip which thus remains intact and can fulfil its intended sealing function.

Abstract: ABSTRACT OF THE DISCLOSURE         An improved method for hardfacing tool joints for earth boring drill pipe.  Annular bands of hardfacing are ap-plied by an apparatus that creates an arc between a consumable steel wire and the tool joint.  The steel wire is reciprocated across the width of the band as the tool joint is rotated. Granules of tungsten carbide flow by gravity from a hopper into the weld puddle.  The flow of granules into the puddle is stopped just prior to reaching the tie-in point.  The arc con-tinues a short distance, creating an overlapping protuberance at the tie in that is free of granules at the surface.  This pro-tuberance can be easily ground smooth with the remainder of the hardfacing.

Title: Integrated coal liquefaction-gasification process
Inventor: CARR NORMAN L
IPC: C10G1/00
Filed: 1979-11-20
Granted: 1982-08-03
Abstract: ABSTRACT OF THE DISCLOSURE         In a coal liquefaction process the yield of liquid coal is increased with a concomitant decrease in the yield of normally solid dissolved coal by recycle of a product slurry containing mineral residue.  In an integrated coal liquefaction-gasification process employing product slurry recycle (14) wherein the net yield of normally solid dissolved coal from the lique-faction zone (22, 26) comprises the entire hydrocarbona-ceous feed to the gasification zone(76), a moderate net yield of normally solid dissolved coal is conducive to an optimized efficiency for the integrated process. However, it is frequently difficult to perform the process at s??ry recycle rates which are sufficiently low to be economically practicable because of a pumpa-bility constraint on the solids level in the feed coal mixing vessel.  In the present process, mechanical operability is improved and enhanced conversion of normally solid dissolved coal is achieved by passing a portion of the liquefaction zone product slurry through a hydroclone (60) with the hydroclone overflow stream (61) constituting a second recycle slurry.  Deployment of the second recycle slurry accomplishes selective recycle of relatively small particles of mineral residue and tends to reduce the yield of normally solid dissolved coal without resorting to excessive recycle rates, con-tributing to optimized efficiency for the integrated process.
