Abstract: ABSTRACT OF THE INVENTION          A  method and apparatus for maintaining alignment of the drill steel or drill rod of a drilling machine in which a midpoint centralizer or indicator ring having an aperture therethrough substantially greater than the diameter of the drill rod or drill steel is used like a rifle sight to indicate the nature and degree of misalignment so that adjustments can be made in the operating mechanisms of the drilling machine or the support and positioning mechanisms for the drilling machine to remove the cause of the misalignment and to return the drill steel to its centered, aligned position in the indicator ring.          In normal operation the drill steel does not contact the indicator ring so that noise transmission and frictional losses normally associated with midpoint centralizers is avoided.          Mechanical contact between the drill steel and indicator ring occurs only to limit the maximum deflection and maximum stress which will occur in the drill steel due to bending. Guided by the indications at the indicator ring a skilled operator can greatly reduce or substantially avoid the occasions when mechanical contact actually occurs.

Filed: 1980-06-17
Granted: 1983-03-22
Abstract: Case 79009 METHOD OF USING RECYCLED MOTHER LIQUORS TO PRODUCE ALDOSIDES ABSTRACT OF THE INVENTION The present invention relates to the preparation of aldoside mixtures, recovering at least a portion of one aldoside component therefrom and reusing the remaining portion of the aldoside mixture prepare addi-tional aldoside. The aldoside mixture may be prepared by slurrying the carbohydrate in alcohol and passing the slurry through a continuous reactor at an elevated temperature under fluid pressure in the presence of an acid catalyst. The resultant aldoside mixture may then be partitioned into a mother liquor portion and an aldoside portion by selectively recovering at least a portion of one aldoside from the crude aldoside mixture with the remaining mother liquor being recycled. Crude glycoside mixtures prepared from starch and methanol slurries are suitable substrates for selectively recovering methyl-alpha-D-gluocpyrenoside. The methyl-alpha-D-gluccpyranoside may be easily crystallized and recovered from the glycoside mixture because of its lower solubility in methanol. me resultant mother liquor (rich in the ramaining components of the glycoside mixture) in combination with freshly added starch and methanol provides a reaction medium which optimizes methyl-alpha-D-glucopyranoside production.

Abstract: Docket No.                     ABSTRACT OF THE DISCLOSURE    A pressurized, fluidized bed combustor including a housing having a combustor chamber therein with a distributor plate closing the lower portion of the housing and arranged above a fluidizer windbox, which, in turn, is arranged above a heat exchanger inlet plenum which is mounted above a bottom of the combustor.  Space above the distributor plate defines a fluidized bed into which a plurality of heat exchanger tubes are disposed.  The cooling fluid is arranged to flow into the heat exchanger inlet plenum and pass into the heat exchanger tubes.  The cooling fluid is passed through vertically elongated tubes which extend upwardly through the distributor plate and into the bed and is circulated first upwardly in an outside space between the tubes and then downwardly through a passage defined in the interior tube for discharge from the bottom of the reactor. The fluidized air is directed upwardly through tuyeres and dis-charges into the bed.  A coal gun is provided for discharging coal into the fluidized bed, and it comprises an outer guide tube which extends from a spaced location above the distributor plate downwardly through the bottom of the combustor chamber and it includes a portion which extends exteriorly of the combustor chamber.  This exterior portion carries a ball valve which has a passage therethrough which makes it possible to insert a coal supply pipe upwardly in the interior of the outer guide pipe and through the passage of the ball valve up to substantially the top of the outer pipe at a location above the distributor plate within the reaction bed.  For withdrawing the coal supply pipe, it is possible to remove the pipe downwardly through the ball valve until the top end thereof is located directly below the ball valve but still within the outer diameter pipe and located within a stuffing box thereof.  At such location, then the ball valve is closed and the ball supply pipe may be withdrawn all the way without reducing the pressure in the reactor.

Abstract: Method and Apparatus for Positioning the Point of Droplet Formation in the Jetting Fluid of an Electrostatic Sorting Device Abstract of the Disclosure A novel method for positioning the point of droplet formation in the jetting fluid of an electrostatic sorting device is disclosed.  The formation of the uniform droplets is carried out via the application of vibrational energy imparted by a transducer to a jetting laminar flow stream. Previously sensed particles contained within the core portion of the laminar stream are subsequently sorted from the stream as part of a subsequently formed droplet, The disclosed method uses the dependency of the droplet formation point on the amplitude of the waveform applied to the transducer and the modulation of this amplitude to control the droplet formation point distance.  The position of the droplet formation point is detected via the use of a light source and photodetector focused on the jetting stream at the position at which the droplet formation point is to be located, and a method for automatically maintaining the breakpoint at that position is described.

Abstract: ABSTRACT OF THE DISCLOSURE IMPROVEMENTS IN OR RELATING TO PIPETTE MEANS          This invention is in the field of automatic chemical (more especially bio-chemical) analysis.  Pipette means are provided in which a circumferentially compressible tube communicates through the lower of two connecting tubes with a pipette tip, and through the upper with a source of diluent. The tube is compressed circumferentially and elastically by fluid pressure applied through a connector into a space surrounding the tube inside a block.  Relief of the pressure allows the tube to expand and draw a sample into said pipette tip, the sample volume being dependent on the fluid pressure applied.  Re-application of pressure expels the sample from the pipette tip.  Any diluent required is supplied through the upper connecting tube, and passes out through the pipette tip. It is important for consistency of results that the tube be compressed elastically, and a suitable material for the tube is latex rubber.  It may be lined with silicone rubber to reduce moisture absorption.  The above-described pipette means improves accuracy of sampling, and diluting and dispensing of liquids, eg blood serum.

Abstract: ABSTRACT            Factors affecting copy quality are continuously adjusted during copying in accordance with the actual charge on the photoconductor relative to a fixed reference potential.  The photoconductor, carried on a moving, partially exposed, constant potential conductive support, is sensed by a probe. The probe supplies a signal as a function of the potential on portions of the photoconductor and the conductive support passing by the probe.  A circuit converts the probe signals into digitized values representing the current photoconductor potential relative to the support.  The digitized values adjust copier parameters to compensate for deviations of photoconductor potential from pre-determined desired values.

Abstract: ABSTRACT      A machine for the over-molding of a thermoplastic material on connectors crimped on the stripped ends of conductors has a conveyor extending from the crimping machine to carry the connectors to three stations.  At the first station, a core is positioned at portions of the connector which have to be kept protected from an over-molding.  A second station has an injection press with tools maintained at a suitable temperature to facilitate introduction therein of an over-molding material. A third station has a press provided with molding tools similar to that of the injection press, but maintained at a temperature lower than that for which an injection of thermoplastic material would be possible.  A process for over-molding connectors with a thermoplastic material in which an over-mold connector is extracted from an injection press before complete cooling of the thermoplastic material involves the carrying of an over-molded connector into a mold of a second press wherein the connector is maintained at a temperature lower than that for which an injection of thermoplastic material would be possible.  The transfer of the connector from the injection press to the second press is sufficiently rapid to prevent deformation of the thermoplastic material which is still not solidified.
