Abstract: ABSTRACT OF THE DISCLOSURE           A method of coating a sheet metal burner assembly base plate formed of a pair of joined overlying metal sheets having an integrally embossed air-duct formed therebetween is disclosed.  The sheets are substantially entirely immersed in a slurry of ceramic frit and, simultaneously, a volume of the slurry at the exterior of the sheets is pressurized so that ceramic frit particles are forced into crevices existing between the sheets.  The sheets are removed from the slurry and the frit is fired onto the sheets so that the particles driven into the crevices are fused to seal such crevices.

Abstract: ABSTRACT OF THE DISCLOSURE          Detachably mounted on a sliding table are a plurality of part tape or belt feed units each of which intermittently feeds to a lead wire cutting station a part tape or belt holding a large number of parts of the same type, each of which has lead wires extended in opposite directions and coaxial-ly of a main body of the part and attached adjacent to their ends to parallel strips of tape or belt in equidistantly spaced apart relationship with the lead wires of the adjacent parts.          The sliding table moves in either direction so that the desired part tape or belt feed unit is moved to a part feed position at which the desired part tape or belt feed unit feeds the part to the cutting station.  At the cutting station a cutter unit cuts  off from the part tape or belt the lead wires of the part, thereby separating therefrom the part having lead wires of a predetermined length, and the lead wires are bent in the same direction.  Thereafter, the cutter unit is rotated and moved to a lead wire insertion position, and a pusher in the cutter unit pushes the shoulder portions of the lead wires so as to insert them into predetermined apertures in a printed circuit board.  The lead wires of parts of any sizes and configurations may be inserted, and the cutter unit effects the cutting, forming and pushing toward the insertion position of the lead wires, whereby the lead wire insertion speed may be substantially increased.

Abstract: DOUBLE CUFFED ENDOTRACHEAL TUBE                       ABSTRACT      A double cuff for endotracheal tubes is designed with two inflatable balloons, shaped to fully occupy the spaces above and below the open larynx.  The two cuffs have a common inflation channel and therefore after their inflation are in free communication with each other.  The lower cuff with its thin non-elastic walls rests in the upper trachea, applying a pressure against the walls of the upper trachea and sub-glottic structures determined by the behavior of an upper cuff whose walls are elastic.  This elastic cuff occupies the space immediately above the larynx and extends slightly into the pharynx.  Elastic properties of the upper cuff confer, in effect, a pressure relief system to the lower non-elastic cuff as a result of their interconnection through the common inflation channel.  A short segment of uncuffed tube between the cuffs allows correct anatomical placement of this segment at the level Or the larynx, insuring that the inelastic lower cuff rests below the larynx and the elastic upper cuff above the larynx.  The proximity of the two cuffs results in an anchor effect around the glottic structures.  Maintenance of a seal at low intra-cuff pressures in the trachea and larynx eliminates ciliary injury despite relatively high lung-inflating pressure because the latter is intermittently transmitted into the lower cuff which in turn is pressed against the subglottic structures to provide a satisfactory non-leaking seal for ven-tilation.  Simultaneously the cuffs protect the larynx and trachea from aspiration of secretions from the upper airway into the lung and anchor the tube to prevent both bronchial intubation and inadvertent extubation.

Abstract: 1950-65a ABSTRACT OF THE DISCLOSURE              Information on a patient chart is imaged onto a first portion of a dielectric receptor sheet simultaneously with, prior to or subsequent to exposure of a second portion of the receptor sheet to object-modulated X-rays in an ionography imaging chamber.     The sheet has an outer layer consisting of polyvinyl chloride or polyethylene terephthalate and is brought into intimate contact with a chart at a station where the chart and the overlapping first portion of the sheet are exposed to electromagnetic radiation issuing from an electronic flash unit.  This results in the formation of a latent image of the information on the first sheet portion, and such image is thereupon converted into a visible image, either on the receptor sheet or on a separate sheet, in accordance with a xerographic developing technique by resorting to toner particles.  The sheet can be reused by neutralizing its charge, e.g., by heating its layer. to a temperature approximately 10°C. above the freezing point of the material of the layer, by moving the sheet relative to an AC corona discharge device (or vice versa), or by washing the layer with alcohol.

Abstract: TITLE ACYLATION OF AMINO ACIDS           INVENTOR Alenka. M. Paquet ABSTRACT OF THE DISCLOSURE N-monosubstituted derivatives of diamino acids are prepared by the reaction of succinimidyl esters of car-boxylic acids or substituted carbonic acids with the, un-protected diamino acid.  The acylation preferentially occurs at the side chain or terminal amino group of the diamino acid.  For example, selective acylation of the terminal amino group of lysine occurs without first having protected the 2-amino group.  Such acylation has application in the preparation of inter alia N6-palmitoyl-lysine.  A novel advantageous route for preparing the succinimidyl esters is also described.

Abstract: ABSTRACT OF THE INVENTION     A nuclear imaging system includes an analog signal processor which features analog data derandomization for minimizing data loss due to pulse pile-up. A scintillation detector provides a sequence of analog data pulses to the signal processor, the data pulses characterizing the energy level and situs of respective radiation events striking the detector.  The signal processor includes sets of novel peak detectors and of sample and hold circuits which are serially connected and are operated to derandomize or space the sequence of analog data pulses so that the system can process pulses corresponding to photopeak events occurring only 1.5 micro-seconds apart.  The analog data pulses are stored in analog pulse form in the peak detectors and are selectively trans-ferred into the sample and hold circuitry from which they are transferred to the display mechanism.  The signal processor is multiplexed with several data input channels for accommo-dating dual isotope operation.  A control unit is provided which controls the data processing cycle according to a pre-determined processing time, or according to signals from external system apparatus.  The control unit provides automatic resetting for assurance that the signal processor does not become locked into an inoperative, nondata processing state.          The novel peak detectors are controlled by the control unit and feature input biasing for increased detection sensitivity, proportional dumping for discharging the stored peak value at a rate proportional to the value of the stored peak, and selective input data gating so that only the peak containing portion of the input signal is input into the detector.

Abstract: ABSTRACT OF THE DISCLOSURE                  This invention is directed to a novel rubber seal which is formed in place in a circular entry port in a concrete manhole for a sewer pipe, thereby providing a water-tight seal between the manhole rim and the sewer pipe, and a novel method of forming the seal in place in association with the concrete manhole when it is formed of concrete.  The invention comprises a sealing ring for sealing the annular opening existing in a plane between an inner circular shaped member and an outer circular shaped member comprising a generally circular ring member having a generally V-shaped cross-sectional shape, the two legs of the V-cross-section shaped sealing ring member being embedded in the peripheral wall of the outer circular shaped member such that distortion laterally from the plane of the protruding base portion of the V-shaped sealing ring member in either direction places a compression force on one of the legs of the V-shaped sealing ring member, thereby tending to increase the width and tighten the fit of the leg embedded in the wall and enhancing the sealing properties of the sealing ring in association with the wall of the outer circular member.  The invention also comprises a novel method of embedding the legs of the V-shaped ring member in the peripheral wall of the outer circular shaped member while the member is being cast of settable material.
