Abstract: ABSTRACT  OF THE DISCLOSURE            A molding composition is disclosed for forming in a single step a natural sandwich foam product having a cellular core and a thick, densified outer layer.  A hard, particulate filler material such as fly ash is admixed with an unreacted, rigid polyurethane foam system, together with density distribution control agent such as carbon tetra-chloride which lowers the viscosity of the admixture.  In molding, the mold cavity is charged with the admixture and the foam reaction is permitted to occur with the mold closed. The resultant, filled foam product has a thick outer layer formed adjacent the mold surface of substantially greater density than its core.  In the densified layer, both the polyurethane ant filler material components of the resultant product are concentrated to provide over three times the density of the core structure.  Formulations are set forth which provide substantial layer thickness and an outer sur-face having a durometer hardness value of 50 or greater over the entire surface area.  If desired, one or more barrier members may be provided in the mold cavity in order to cause the generation of a densified region in the resultant product at the pressure barrier during the foam reaction, thereby reinforcing the core to increase the structural strength of the product.

Abstract: ABSTRACT OF THE DISCLOSURE            A pile extruder machine includes a hopper and a head or mandrel assembly extending from a support, into moulding chamber assembly. Feed augers are provided on each side of head or mandrel and these feed augers compress concrete from the hopper into the moulding cham-ber around the head or mandrel thus forming the pile and the compression moves the machine forwardly so that the pile is extruded rearwardly upon a pallet. A die assem-bly forms link of coil reinforcing around a coil support tube and the die assembly can be adjusted so that both the pitch and diameter of the lengths of coil can be adjusted.          These coils are fed into the concerete mass at the base of the hopper and surround longitudinally extending reinforc-ing wires.

Light having spectral components periodic in frequency is collec-ted, collimated and transmitted by light conditioning means to a first interferometric means.  The first interferometric means selectively separates a preselected periodic spectrum from the light and transmits such spectrum in the form of a fringe having an intensity derived from and substantially equal to the combined intensities of the transmitted spectra.  A second interferometric means adapted to receive the fringe transmits the preselected periodic spectrum thereof in the form of a modified fringe pro-viding a detectable signal.  The portion of total intensity of the modified fringe derived from the combined intensities of the transmitted spectrum is greater than that of the fringe in the presence of unwanted spectra.

Abstract: Abstract of the Disclosure An improved gas scrubber is provided which is particularly suited for cleaning and cooling the exhaust gases from a diesel powered mine vehicle.  The invention is embodied in apparatus including an enclosure which is partially filled with a liquid such as water.  An inlet for the exhaust gases is located above the liquid level, as is also an outlet for the cleaned gases to escape.  A tube connected to the inlet extends downwardly to below the water level, then changes direction and extends upwardly with constantly increasing cross section and with at least some portion of it in curvature to an open end interiorly of the enclosure and above the liquid level.  One or more orifices in the submerged portion of the tube admit water droplets which are sucked into and turbulently mixed with the high velocity gases in proportion to the amount of combustion exhaust from the engine.  The water droplets and particulate matter are separated from the gas stream by the combination of centrifugal force and their own gravity when the gas stream is slowed down.                             -1a-

Schriber ABSTRACT OF DISCLOSURE                   A charged particle beam deflector having a bimodal resonant-cavity through which a charged particle beam is passed along the cavity axis.  The cavity is excited in a first mode by applying a first rf signal to the cavity through a first magnetic feed loop on the side of the cavity, and in a second mode orthogonal to the first mode by applying a second rf signal to the cavity through a second magnetic feed loop located on the side of the cavity at a circumferential angle of approximately 90° from the first feed loop.  The first mode deflects the beam along a first diametric axis passing through the cavity axis and the first loop location and the second mode deflects the beam along a second diametric axis which is substantially perpendicular to the first diametric axis.  The rf signals to the feed loops are normally of identical frequency but may differ in amplitude and in phase from one another or from the beam to provide various controlled scan patterns.
