Abstract: ABSTRACT OF THE DISCLOSURE    A device adapted to be interposed between the usual carburetor and manifold of an internal combustion engine, or the like, for receiving the fuel-air mixture from the carburetor and discharging same into the manifold, said device comprising three components or stages:  a rotor member, a sonic vibrator, and a heated grid means.  The rotor member is mounted in the flow stream of the fuel-air mixture and is rotated by the air intake for causing oscillation of the fuel-air mixture from the carburetor.  The fuel-air mixture the enters the sonic vibration stage which causes a molecular mixing of the fuel with the air.  The mixed fuel-air is then passed through the heated grid or screen, which not only straightens out the path of the flow stream of the fuel-air mixture, but also promotes vaporization of the fuel-air mixture impinging the screen, and receiving the heat by radiation.          A magnetic force field is possibly established in the area of the screen or grid which magnetically affects the molecular structure of the hydrocarbon content of the fuel-air mixture to provide a more efficient power conversion of the fuel-air mixture.

Abstract: ABSTRACT OF THE DISCLOSURE          An apparatus for independently and simultaneously rewinding a plurality of slit strips into rolls includes a single elongate contact roller and a plurality of rewinding cores arranged side by side in at least one row parallel to the axis of the contact roller. Each rewinding core is inde-pendently supported for rotation by at least one vertically extending support arm, the support arms being pivotally connect-ed to a common support base which can be positively retracted horizontally away from the contact roller.  During rewinding, as the diameter of strip rolls wound onto the rewinding core increases, the core support arms are moved angularly from their vertical position.  The angular displacement is detected to automatically control the retractive movement of the support base such that the core support arms are kept substantially vertical while maintaining the wound rolls on the cores in constant engagement with the contact roller.

Abstract: AIR BLEED CONTROL FOR CARBURETOR IDLE SYSTEM            Abstract of the Disclosure A carburetor for an internal combustion engine has an idle or low speed system in which air is bled into the idle fuel passage.  An air bleed valve member controls the amount of air flow through an air bleed port for the idle fuel passage and a diaphragm operated control is connected to the air bleed valve member to control the movement of the valve member.  The diaphragm operated control has an air chamber on one side of the diaphragm and a vacuum chamber on the other side of the diaphragm with a restricted opening between the air and vacuum chambers.  Upon a rapid engine deceleration to an idle position, the air bleed valve member is moved to a position to provide maximum air flow to the idle fuel passage for a limited period of time until the pressure is equalized between the vacuum chamber and the air chamber through the restricted opening.  Such an arrangement permits fuel which has previously condensed on the walls of the manifold to be leaned for a short period of time after a rapid increase in intake manifold vacuum which results from rapid engine deceleration to an idle position.

Title: Portable drilling machine
Inventor: VARICH MIKHAIL S
IPC: E21B19/08
Filed: 1976-08-25
Granted: 1980-10-14
Abstract: The present invention relates to drilling equipment. The portable drilling machine comprises a derrick having longitudinal racks guiding a vertical traverse mechanism carrying a traverse having a means designed for rotation of a drill pipe during the drilling operation, said pipe being positioned longitudinally in the derrick in alignment with the drilling axis; a pulldown unit connected through a closed flexible transmission with the vertical traverse mechanism and the traverse to feed, during the working run thereof, the drill pipe to the bottom of the hole and, during the reverse run thereof, to raise the drill pipe; and a clamp designed for gripping the drill pipe on completion of the working run of the vertical traverse mechanism and the traverse and being mounted at the base of the derrick. The means for rotation of the drill pipe is designed as a powerdriven rotating chuck mounted in the traverse.  Said chuck grips the drill pipe during the drilling operation, and can, during an idle run when it is unclenched together with the vertical traverse mechanism, regrip the pipe while the drill pipe is held by a clamp.  Such drilling machines can make vertical and angle holes to the full depth by using only one long drill pipe to a most efficient manner as to rotation rate thereof and load on the bit, which makes such a drilling machine a high-capacity design.

Abstract: ABSTRACT OF THE DISCLOSURE           An improved drive-unit arranged within the step-belt of an excalator, the drive-unit consisting of an electric motor, tran-smission, and hand-rail drive, the drive-shaft for the transmis-sion also serving as the main drive-shaft for the said step-belt.  In one known drive arrangement for escalators, the drive for the hand-rail, arranged within the step-belt, is combined into a unit with the main transmission in order to achieve a compact drive. In this arrangement the hand-rail driving wheels are connected to the drive by means of cardan shafts.  This known arrangement has the advantage of taking up less space and being more reliable than con-ventional drives.  However, in view of the space restrictions as-sociated with escalators, a design occupying even less space and of less complex construction would be of greater advantage, while being less costly.  The present invention proposes to provide a drive arrangement for escalators which will take up less space than known similar arrangements and which, at the same time, is economi-cally more satisfactory due to its simplified design.  According to one embodiment of the present invention, this is achieved in that the rotor constituting the housing for the electric motor is mounted floatingly upon the imput shaft of a transmission.  Torque from the transmission is absorbed by a torque support arranged upon the hand-rail shaft.  The hand-rail shaft extends at right angles to the imput shaft and is driven by a chain.

Abstract: ABSTRACT OF THE DISCLOSURE         An improved polyvinyl halide or a vinyl halide copolymer containing up to 50 percent of a comonomer can be obtained by post polymerizing in a single stage or two-stage bulk process in contact with a base polymer. the same or different monomer as the monomer used to form the base polymer.  Compositions produced by the process of the invention are useful in making films, coated fabrics and molded objects.  The liquid phase post polymerization process of the invention is applicable to base polymers in powder form prepared by emulsion, suspension and bulk polymerization processes.  The base polymer can be present in a polymerization mixture in which only a partial amount of monomer has been converted to base polymer such as in a two-stage polymerization process or the base polymer can be used in dry, solid form.  Polymers of the invention have improved bulk density and reduced plasticizer uptake and can be used to prepare fabric coatings.  Copolymers prepared by the novel post-polymerization process of the invention which show increased impact strength in addition to improved bulk density and reduced plasticizer uptake are useful in the preparation of molding compounds.  In the bulk polymeri-zation process of the invention, the addition of the same monomer or monomers or a different monomer or monomers subsequent to the partial conversion by a two-stage bulk process of polymerization of the vinyl halide monomer or monomers or vi??? halide monomer and comonomer, results in higher yield than can be obtained in the same reaction
