Title: Processing of melt processable liquid crystal polymer by control of thermal history
Inventor: WISSBRUN KURT F
IPC: D01D1/09
Filed: 1981-07-03
Granted: 1984-06-12
Abstract: ABSTRACT OF THE DISCLOSURE         A process for the extrusion of melt processable liquid crystal polymer which provides improved process-ability characteristics is provided.  The process comprises the steps of subjecting the liquid crystal polymer to an elevated temperature between the DSC transition temperature and the degradation temperature of the polymer; cooling the liquid crystal polymer to a processing temperature which is between the DSC transition temperature and the elevated temperature and at which the liquid crystal polymer is less subject to degradation than at the elevated temperature; and extruding the liquid crystal polymer into the form of a shaped article having mechanical properties which are improved over those of articles formed from liquid crystal polymer which has not been subjected to the elevated tem-perature.  Preferably, the liquid crystal polymer exhibits at the elevated temperature a reduction by at least a factor of 5 in the melt viscosity of the liquid crystal polymer, as compared to the melt viscosity at the DSC transition temperature, without significant degradation of the liquid crystal polymer.  The reduction in melt viscosity is substantially retained by the liquid crystal polymer at the processing temperature, and the liquid crystal polymer is extruded into the form of a shaped article while the reduction in melt viscosity is thus retained.  By employing the process of the present invention, melt process able liquid crystal polymers can be conveniently processed at temperatures near the DSC transition temperature rather than at the higher tempera-tures commonly encountered in the prior art at which de-gradation is more likely to occur.

Abstract: SYSTEM FOR PERMEABILITY LOGGING BY MEASURING STREAMING POTENTIALS             ABSTRACT          Method and apparatus for investigating earth formations according to the present invention include positioning an opening of a fluid reservoir in contact with the surface of a earth formation to he investigated and injecting the fluid at high pressures through the opening into the formation at frequencies within a range up to 1 khz to cause quasi-static flow in the formation.  Streaming potentials generated in the formation by this flow are detected by appropriate electrodes and the output of the electrodes, representative of the generated potentials, is then processed to determine a characteristic response time of these streaming potentials. Thereafter, from a knowledge of the characteristic response time of the detected streaming potentials a measurement of the permeability of the formation is derived.

Abstract: ROGERS, BERESKIN & PARR                C A N A D A     INVENTION:    STACKABLE LID                 INVENTOR:     GEORGE COTRONEO .                 ABSTRACT OF THE DISCLOSURE     A molding method and lid construction particularly suited to the molding of stackable lids of very thin construction is described.  The method involves injecting a molten thermoplastic material whose cavity defines a lid top having top and bottom spaces, a circular alignment shoulder raised from the top face inset from the periphery of the top, and a circular sidewall extending perpendicularly from the bottom face.  The cavity also defines a relatively thin flange that extends radially inwardly from the lid sidewall and has a flat upper surface oriented generally perpendicular to the sidewall to provide a very positive stop (for engagement with the upwardly extending lip circumscribing the opening of a conventional container) despite the very thin construction of the flange.  The lid is removed from  the mold when partially set, whereafter radial contraction of the lid sidewall dimensions the bottom edge to more closely receive the alignment shoulder of an identical lid.  The distribution of material in the sidewall accentuates radial contraction in the vicinity of the bottom edge of the sidewall where it is most required.

Abstract: ABSTRACT OF THE DISCLOSURE   An agitator type washing machine having a tub, a fabric receiv-ing basket mounted in the tub, a recirculating pump for recirculating liquid from the tub to the basket during wash and rinse operations, and a liquid sensor responsive to the volume of liquid retained in the tub, which operatively combine to automatically control the volume of liquid delivered to the washing machine during each fill operation according to the size of the clothes load in the basket.  Vertically spaced tiers of drain holes are formed in the sidewall of the basket to permit liquid flow from the basket to the tub.  The tiers are arranged such that when the liquid level in the basket is lower than the lowermost tier unimpeded by the load in the basket, liquid flow from the basket, impeded by the load, is exceeded by the liquid flow into the basket from the tub and from the external supply, causing liquid to accumulate in the basket, but not in the tub.  When the liquid level in the basket rises to the level of the lowermost unimpeded tier, cumulative liquid flow from the basket through the impeded and unimpeded tiers exceeds the liquid flow into the basket, causing liquid to accumulate in the tub.  The level sensor is operative to terminate fill and enable agitation upon detec-tion of the accumulation of a predetermined volume of washing liquid in the tub.

Abstract: Abstract of the Disclosure The invention relates to a method of increasing the rate of hydration of polymeric viscosifiers/fluid loss additives in heavy brine well servicing fluids containing zinc bromide.  It is based on the discovery that the rate of hydration of activated hydroxyethyl cellulose (HEC) in aqueous brines is greatest in brines containing no zinc bromide or in brines containing the largest possible concentrations of zinc bromide.  This is achieved by either admixing a hydroxyethyl cellulose composition with a first solution containing at least 30% by weight zinc bromide to produce a viscosified solution and thereafter mixing this viscosified solution with a second solution containing calcium chloride, calcium bromide or mixtures thereof, or, admixing a hydroxyethyl cellulose composition with a second solution containing calcium chloride, calcium bromide or mixtures thereof to produce a viscosified solution and thereafter mixing this viscosified solution with a first solution containing zinc bromide.

Abstract: ABSTRACT OF THE DISCLOSURE     Apparatus and technique for monitoring physiological para-meters.  An acoustic sensor or microphone is placed in close proximity to the chest of a patient having one or two prosthetic heart valves.  These heart valves produce clicks characteristic of opening and closing action.     The acoustic sensor picks up the sound of these clicks and transfers them as electrical energy to a transmitter unit.  The transmitter unit processes the analog signal, converts it to a digital signal and establishes the key timing factors involved.  This digital data is stored in a memory buffer within the transmitter.  Subsequently, this information is modulated and placed on telephone lines for transmission to a central monitoring site.     At the monitoring site a demodulator returns the data to baseband digital signals.  A computer at the central monitoring site displays the information in the time domain and also converts the information for display in the frequency domain.

A slurry tube is within the venturi tube and has an upper end at the restricted cross section of the venturi tube and a lower end extending below the venturi tube adapted to be positioned on one side of the conduit and adjacent the seabed.  Disaggregating nozzles are slidably mounted about the lower end of the slurry tube having tele-scopic means connected thereto for vertically moving the nozzles relative to the seabed, to thereby control disag-gregation.  Means are connected to the nozzles for feeding water under pressure therethrough whereupon the jets of water from the nozzles disaggregate the seabed and form a slurry.  Means are connected to each of the venturi tubes for feeding water under pressure therethrough wherein a negative pressure is created which causes the slurry to be withdrawn from the seabed into and through the venturi tubes.  Guiding means are provided for positioning the device on the conduit as it moves therealong for digging up and burying the conduit.
