Abstract: La divulgation décrit une capsule de bouchage à vis, moulée d'une seule pièce en matière plastique, et comportant une jupe interne d'étanchéité destinée à coopérer par forçage avec l'intérieur d'un goulot de bouteille ou flacon.  Cette capsule peut comporter éventuellement une lèvre concentrique à la jupe interne et destinée a coopérer, en fin de vissage de la capsule. avec la partie supérieure du goulot de bouteille ou de flacon. Subsidiairement, la capsule comporte une troisième lèvre d'étanchéité destinée à coopérer avec la partie supérieure externe du goulot de bouteille ou de flacon.  La capsule est caractérisée par le fait:  que la jupe d'étanchéité interne comporte une portion supérieure de hauteur réduite présentant, au début du vissage, une faible conicité tournée vers le haut, et dont le diamètre externe, au moins à son raccordement avec le fond de la capsule, est supérieur au diamètre interne maximum du goulot, compte tenu des tolérances de fabrications.  Cette partie initialement conique se prolonge vers le bas par une autre portion conique dirigée vers l'intérieur de la bouteille et se termine par une collerette sensiblement radiale, dont la périphérie est susceptible, en fine de vissage de la capsule sur le goulot, de se retourner vers le haut de façon connue en soi, en formant un deuxième joint d'étanchéité par rapport à la paroi interne du goulot de bouteille, au-dessous du premier joint constitué par la portion supérieure de la jupe interne d'étanchéité.  La troisième lèvre d'étanchéité externe susvisée. qui est circulaire et continue sur toute la périphérie du goulot, coopère avec une partie cylindrique lisse de hauteur non négligeable et prévue audessus du filetage externe de ce goulot de bouteille.

Abstract: CANNISTER PURGE VALVE ASSEMBLY ABSTRACT OF THE DISCLOSURE A cannister purge valve assembly for a vehicle emissions control system is disclosed which includes a housing defining a chamber which is divided into a pair of sections by a diaphragm carried by the valve housing. One of the sections has inlets communicated to the vehicle fuel tank and to the vapor absorbing cannister and an outlet which is communicated to engine intake manifold vacuum when the vehicle engine is operating.  The other section is provided with an inlet which is communicated to the spark port on the vehicle carburetor so that the other section is communicated to a vacuum level when the engine is running.  The inlet communicated to the cannister and the outlet communicated to the intake manifold terminate in a pair of coaxial tubes which extend into the chamber.  Corresponding ends of the tube are substantially coplanar to define a valve seating area.  A spring yieldably urges the diaphragm into sealing engagement with the valve seating area on the coplanar ends of the tubes, to thereby pre-vent communication between the two inlets and between either of the inlets and the outlet unless the pressure level in the vehicle fuel tank raises above a predetermined pressure level sufficient to actuate the diaphragm, whereupon  he vapor in the fuel tank is absorbed by the canni-ster.  When the vehicle engine is started, the diaphragm moves away from the valve seating area to permit purging of the cannister through the outlet.

Abstract: STRAND CARRIER FOR A STRAND FABRICATING MACHINE                    Abstract of the Disclosure A strand carrier for a strand fabricating machine includes a support structure and a shaft mounted thereon.  A hub is mounted for rotation around the shaft for receipt of a bobbin of strand thereon for common rotation about the shaft.  A helical clutch spring includes a first end secured to the support structure so that it closely encircles an outer cylindrical surface of the hub to restrict rotation thereof.  A clutch release sleeve is rotatably mounted on the support structure around the clutch spring and receives the other end of the spring in an opening therein so that rotation of the clutch release sleeve in a first direction will tend to unwind the clutch spring to reduce friction on the hub.  A control lever pivotally mounted on the support structure has a first section which includes a strand guide thereon and is connected to the sleeve.  The lever is biased in a direction tending to rotate the sleeve in an opposite direction from the first direction.   A plurality of additional strand guides are mounted on the support structure to direct the strand being unwound from the bobbin to and around the strand guide of the first section to apply a resulting force on the strand guide during unwinding in a direction in opposition to the biasing of the lever.

Abstract: ABSTRACT OF DISCLOSURE       A frequency-comparing device is arranged when in its no-output condition to respond to a pulse from a first one of two inputs by supplying a predetermined one of the two outputs until a pulse of another sequence arrives to terminate this output, whereafter the pulse next arriving will restore the same output if that pulse comes from the first input whereas if that pulse is one of the second input it will initiate the other output. Assuming that the pulse sequence from the first input has a frequency proportional to the speed of a motor unit and the pulse sequences from the second input consists of time pulses produced for example by a reference oscillator and that the output initiated by the arrival of a pulse from the first input is used as a drive-low input for the speed regulation unit of the motor while the other output constitutes a drive-high inputs for the same unit and that furthermore the pulse frequency derived from the motor speed is arranged to be equal to that derived from the reference oscillator when the motor runs at its desired speed, it will be found that when the motor speed is higher than the desired speed two pulses from the first input will from time to time occur within the interval between two consecutive pulses from the second input.

Abstract: ENHANCEMENT-MODE FETS AND DEPLETION-MODE FETS WITH TWO LAYERS OF POLYCRYSTALLINE SILICON             Abstract of the Disclosure Enhancement-mode field-effect transistors (FETs) and depletion-mode FETs are provided on the same semicon-ductive substrate using five basic, lithographic, pattern-delineating steps.  The five lithographic masking steps delineate in order:    (1)   the field isolation regions;           (2)   the enhancement-mode FET gate electrodes;           (3)   the depletion-mode FET gate electrodes;   (4)   contact holes or vias to FET source and drain regions and to depletion-mode FET gates; and (5)   the high electrical conductivity metallic-type interconnection pattern.         The low-concentration doping required to form the depletion-mode channel regions is provided after the second but before the third pattern delineation step, while the high-concentration doping to form the source and drain regions is provided after the third pattern delineation step.  In order to obtain the desired device structure, it is necessary to use two separately defined polycrystalline silicon regions for the gate electrodes of the enhancement-mode and depletion-mode FETs.

Abstract: ABSTRACT         The means for the cleaning and self-cleaning of an electrostatic precipitator is especially suited for adaptation to an electronic air cleaner comprised of an ionizer unit and a collecting cell unit adapted to be included in tandem within a suitable cabinet; means to bring air to be cleaned through these units are also provided, and these may or may not be an integral part of the cleaner.  The ionizer unit may include support members for a plurality of ground plates between which are located ionizing wires which normally carry a low current but high voltage.  The collecting cell unit includes support members for a plurality of grounded collecting plates and there are a plurality of charged collecting plates suitably among the grounded collecting plates, the grounded plates and charged plates being out of electrical contact with one another.        The means for cleaning and self-cleaning includes provision for imparting pulsations or vibrations directly to the grounded plates via the various support members on which such plates are mounted.  An important refinement of such means is to provide for varying these pulsations or vibrations to effect a change in their harmonic mode.  By effecting a change in the frequency of the pulsations or vibrations, or oscillations, a greater plate area is affected and a more thorough breaking away of the precipitated contaminants from the plates is effected.

Abstract: ABSTRACT      A continuous process for simultaneously producing a stream of cleaned purified synthesis gas having a mole ratio H2/CO in the range of about 2 to 12, and a separate stream of CO-rich gas. In one embodiment of the process, cleaned and purified methanol synthesis gas and substan-tially pure carbon monoxide are produced. Methanol may be synthesized and optionally catalytically reacted with the substantially pure carbon monoxide to produce acetic acid. In the subject process, the effluent gas stream directly from a free-flow unpacked noncatalytic partial-oxidation synthesis gas generator is split into two streams which are simultaneously processed in two separate trains. In the first train, one of the split streams is cooled by indirect heat exchange in a gas cooler and than further processed to produce a stream of cleaned and purified synthesis gas, a H2-rich gas stream, and the product stream of CO-rich gas and preferably substantially pure CO. Simultaneously, the second split stream in the second train is cooled by direct quenching in water in a quench drum, cleaned, subjected to catalytic water-gas-shift reaction, and purified to produce a second H2-rich gas stream. The product stream of cleaned and purified synthesis gas having a mole ratio H2/CO in the range of about 2 to 12 is then produced by mixing together at least a portion of the cleaned and purified synthesis gas stream from the first train with 0 to 100 volume % of the H2-rich gas stream from the first train and at least a portion of the H2-rich gas stream from the second train.

Abstract: PIPE QUALITY MONITORING MECHANISM                    By Roy J. Gromlich and Kilian H. Brech and John David Cist Abstract of the Disclosure As an ultrasonic transducer is continuously rotated about a pipe which is fed axially through a water-filled cavity, it sends sufficient periodic pulses to the pipe to cover essentially the entire pipe surface.  The transducer also receives reflections from the outside and inside walls of the pipe from which information about pipe qualities is derived.  A thickness processor module employs precision peak detectors in various circuits, including one in which flaw conditions are compared on successive rotation of the transducer in order to verify the presence of a flaw before an alarm is indicated.  The thickness processor  module may also provide display information about maximum and minimum values, average values, and eccentricity.  In addition to the precision peak detector, there is also provided a rate of change filter which monitors rate of change of wall information and detects flaws by, any major rate of change.  If tolerances are exceeded in any respect or rate of change indicates a cavity or other discontinuity in the surface, alarms may be sounded, but before an alarm is sounded, verification is preferably accomplished by alarm verifica-tion, memory and logic means,
