Abstract: ABSTRACT OF THE DISCLOSURE     A hand truck for transporting loads which obviates the necessity of tilting the load prior to positioning the latter on the hand truck.          The hand truck is devoid of any bottom plate and carries a pair of jaws clampable on the top flange, or bead, of a load and which suspends the load along the inclined truck frame when the truck frame is moved about on its wheels.  The hand truck is further characterized by the provision of a foot-operated jack mechanism to raise the clamped load along the truck frame, 80 that the load may be deposited at any desired elevation when its destination is reached.  The jaws are so arranged that they automatically increase the clamping pressure clamp on the load bead, or top flange, when the load exerts a downward pull on said Jaws.  The hand truck has, in addition to the usual pair of wheels, a pair of feet on which the hand truck is supported when in upright position with the wheels off the ground, ready to grab the load; these feet come off the ground when the wheels come in contact with the same to move the load about.  The jacking mechanism can raise the load to such a position that its center of gravity will fall between the feet and wheels, so that the hand truck, with its load, can be left unattended, since it is stable with both feet and wheels supported on the ground.

Granted: 1979-12-25
Abstract: A B S T R A C T   The invention is directed to a clamp for holding a workpiece to a work surface having an aperture formed therein. The clamp includes the main support arm having one end portion adapted for insertion into the aperture in the work surface. A clamping arm is pivotally connect-ed to the main support arm above the above-mentioned end portion and the clamping arm defines a clamping surface for engaging the work-piece placed on the work surface. A first lever arm is pivotally con-nected to the main support arm and a second lever arm has one end pivotally connected to the first lever arm and another end pivotally con-nected to the clamping arm. Suitable structure is provided for apply-ing a force to the pivot mutually connecting the first and second lever arms to cause the lever arms to transmit respective forces to the main support arm and the clamping arm causing, in turn, the main support and the clamping arm to rotate with respect to each other so that the main support arm tightly engages the wall defining the aperture in the work surface and so that the clamping arm tightly engages the workpiece. The clamp also can be adapted to hold a workpiece to a workbench having no aperture therein. A clamping arrangement in-cludes a member defining a work surface and having at least one aperture formed therein and the clamp. The clamp and member tightly hold the workpiece.

Abstract: ABSTRACT OF THE DISCLOSURE           A fuel nozzle for use with gas turbines is disclosed. The fuel nozzle includes a centrally disposed orifice for dis-charging fuel into a combustion chamber.  A first annular passage surrounds the fuel orifice and discharges primary air adjacent the exit of the fuel orifice for effecting atomization of the fuel and mixture of the air with the fuel to provide a fuel/air spray having a predetermined spray angle.  A second annular passage for supplying secondary air is provided surrounding the first passage.  This second passage is formed to  supply air in a manner which creates a relatively low pressure substantially at the base of the fuel/air spray. When operating at the low fuel flow rates corresponding to low loads, air is supplied only through the first air passage and a relatively narrow spray angle, with a substantial concentration of fuel, is achieved. In a specific embodiment, as the load increases secondary air is supplied with a swirling motion through the second or outer annular passage and creates a vortex of rotating air flow, result-ing in a reduction in static pressure at the base of the spray formed by the mixture of fuel and primary air.  The reduction in pressure at the base of the spray causes the spray angle to be increased and enhances fuel and air mixing.  This improves com-bustion and reduces smoke emission.  In other embodiments, if desired, secondary air may be supplied at any fuel flow rate to provide the optimum spray angle for any giver condition.  The spray angle is controllable independently of the fuel flow rate.

Abstract: ABSTRACT        Transmission of a slurry along a pipeline by ultrasonic sound waves introduced at an angle to the direction of flow of the slurry particles to intersect the moving particles with a forward and lifting component. Ultrasonic generators or transducers are placed along the bottom of a pipeline at preselected angles relative to the pipeline and flow of material therealong. The ultrasonic waves are in the nature of mechanical waves and may be of a given frequency for specific types of solids. The slurry for which this apparatus is particularly adapted is a slurry of coal particles in the range of approximately 30 to 70% solids by weight with a general spatial concentration of approximately 50%. The mechanical ultrasonic waves propagating in the slurry, which is an elastic body, lift the particles by the angular components of the waves and propel the particles along the pipeline by the horizontal components of the ultrasonic waves. The ultrasonic transducers are of known forms and are mounted along the pipeline in predetermined spaced relation with respect to each other and open to the pipeline to propel the particles at an average optimum velocity and elevate the particles above the bottom of the pipeline to prevent settling of the particles in the bottom of the pipeline.

Abstract: ABSTRACT OF THE DISCLOSURE   An apparatus for texturing continuous filament yarn is provided wherein the yarn is fed at a controlled rate and under controlled tension by a pair of feed rolls into a confined crimping zone against a mass of crimped yarn therein, causing the yarn to collapse longitudinally to form crimps which become part of such mass.  Heat and pressure are applied to the yarn mass in the crimping zone to plastically deform the yarn and partially set the crimps.  The crimped yarn mass is then fed at a control-led rate by means of toothed rolls from the crimping zone into a setting zone. Heat and pressure are applied to the yarn mass in the setting zone to fully set the crimps.  The first feed roll is mounted on a first housing and the second feed roll is mounted a second housing.  A special mounting mechanism pivotably attaches the second housing to the first housing so that the second housing is movable about a housing pivot axis between a closed position wherein the second feed roll is adjacent the first feed roll to define a bite therebetween and an open position wherein the second roll is spaced materially from the first feed roll.          An eccentric arrangement can be used to alter the orientation of the housing pivot axis to thus alter the alignment of the second feed roll with respect to the first feed roll.
