Abstract: The following specification discloses a pipe-supporting assembly comprising a hanger and a saddle. The hanger includes a pair of spaced and parallel oppositely and outwardly projecting tongues each having a pair of spaced co-planar slots opening upon the opposite side-edges of said tongues. The saddle is suspended from the tongues and has a pair of spaced substantially circular apertures therein and an open-ended substantially radial slot extending between each aperture and the ends of the saddle. The slots permit the saddle to engage the tongues and be supported rotatably thereby between the co-axial slots.

Abstract: Rotary internal combustion engine of axial sliding vane type has sinusoidal shaped side walls with compensation of the mass forces allowing nearly friction-free and high speed operation with sufficient compression ratio. High power output is believed to make the invention comparable to the well-known Wankel engine.The various designs of the rotary machines can also be used as fluid pumps or fluid-operated motors.

Abstract: Television or other raster display system for displaying the waveform of a time-varying input signal. The scanlines of the raster scan-line pattern are traced on the display screen in a direction orthogonal to the direction of movement of the waveform. The waveform image is constructed on the display screen by superimposing a dot on each raster scanline. These dots are developed by comparing the instantaneous value of the time varying input signal with the instantaneous value of a ramp signal which is synchronized with the raster scanlines.

Abstract: The following invention discloses improvements in thickening devices used in the art of separating solid particles from liquids in a slurry of such particles and liquid having the method steps of causing an imperfectly filtered filtrate to flow by gravity to one outlet and a more perfectly filtered filtrate to flow by gravity toward another outlet.

Abstract: The following specification discloses a tree harvesting apparatus controlled from a light weight tracked vehicle having a rotatable platform for holding a boom apparatus to which a harvester head is hingeably attached. The harvester head comprises shearing means and delimbing knives mounted to a support member which can be positioned by the boom against a tree to be severed and then rotated into a horizontal position for the delimbing and severing of a tree into bolts in proximity and to the side of the control vehicle.

Abstract: The specification discloses a razor assembly comprising a handle having a yoke-shaped extension therein into which a double-edged and double-sided blade cartridge interfits for rotatable positioning between the yoke. An ejector and stop means is located at the base of the yoke to hold the blade cartridge in one of two shaving positions with an ejector actuation means operable from the handle of the razor.

Abstract: A hammer mill has a grinding chamber and means therein sufficient enough to grind grain in one pass through the chamber and throw it directly if desired to a remote point, together with means for adjusting the grinding chamber intake for grain and especially corncobs and a corncob intake metering attachment. The mill hammers have raked back leading edges to accelerate feed particles to a speed less than that of the hammers, to multiply the number of impacts on the grain. The smoothness of the mill wall can be varied by turning channels located in a recess in the wall so that either the web or the flange edges of the channels face inwardly toward the hammers.

Abstract: An oil burner consists of an outer jacket surrounded and spaced from an inner burner tube to provide a surrounding counterflow chamber. Jacket and tube project horizontally inwards from the surrounding combustion chamber wall. Counterflow chamber is substantially closed at both ends. Tube projects inwardly beyond counterflow chamber and terminates in an upfacing burner head. Communication exists at opposite ends of the part of tube surrounded by counterflow chamber. At startup a tongue of flame travels through tube from an injector nozzle. Part of flame counterflows back through surrounding chamber and recirculates through tube. Another part of flame proceeds on to burner head. When parts sufficiently heated, flame in tube is caused to be extinguished and is replaced by hot clear blue flame jets from burner and a multiapertured band in tube within limits of counterflow chamber at end thereof remote from nozzle where counterflow originates.
