Abstract: FIBER BED SEPARATOR AND METHOD FOR SEPARATION OF AEROSOLS FROM GASES WITHOUT RE-ENTRAINMENT                          ABSTRACT           A fiber bed separator and method are provided for separating aerosols of 3 microns and less from gases.  Two fiber beds in intimate contact with one another are used.  The first fiber bed, in the direction of gas flow is of fibers of at least about 5 microns mean diameter packed to a bed voidage of from about 85 to 98%, the fiber diameter and bed voidage being selected such that at design bed velocity and aerosol loading the first bed is not flooded and the residual saturation of said first fiber bed against gas drag on the liquid collected is less than the residual saturation of said bed against gravity drainage of the liquid.  The second fiber bed is packed to a bed voidage of from about 85 to 99% with fibers of equal or greater mean diameter than those in the first fiber bed such that the residual saturation of said second fiber bed against gas drag is greater than the residual saturation of the bed against gravity drainage.  In various preferred embodiments are high efficiency separators using fibers of from about 5 to 20 microns mean diameter in the first fiber bed and from about 25 to 35 microns in the second fiber bed; and high velocity separators using fibers of from about 25 to 75 microns mean diameter in the first fiber bed and from about 30 to 300 microns in the second fiber bed.

Abstract: ABSTRACT Heavy metals such as gold, silver platinum, copper, etc., in the free state, are separated from their ore by applying water and the ore in finely divided form to at least three rotating, inclined,  spiral grooved discs driven from a common shaft.  The grooves are closely spaced and with declining pitch from periphery to an annulus at the center of the disc.  The free metal tends to sink to the bottom of the grooves and the lighter ore is washed away as the metal moves along the spiral grooves to the annulus. The free metal and any remaining ore is fed from the annulus to the succeeding disc and the process is repeated.

Abstract: ABSTRACT OF THE DISCLOSURE     In an electric motor having an external motor cooling fan mounted outboard of one of its rotor shaft bearings, the cup-shaped enclosure for said fan conventionally has its side wall radially spaced from a part of the frame to cooperate there-with in defining an annular outlet through which air from said fan is guided axially across the motor exterior, all around the same.  According to the invention, that outlet is substantially blocked, as by an arcuate air barrier strip, to convert the fan enclosure into a plenum chamber from which pressurized air is forced through the motor interior for substantially greater cooling effectiveness.

Abstract: PLASTIC DOOR LOCK          ABSTRACT OF THE DISCLOSURE     A plastic door lock, sometimes referred to as a door latch, makes use of moldable plastic material for most of the individual parts of the lock assembly with opposite roses adapted to interlock with each other and be held together with a single screw on the axial center line of the knobs and accessible from the outside. When used as a privacy lock unlocking the lock from the outside is pre-vented by pushing the inside knob into a releasble but non-rotatable engagement with the inside rose.  A lost motion connection between the latch bolt and roll back spindle allows the door to be closed without damage to the latch bolt when the inside knob is locked.  Inherent resiliency in the material of the latch bolt case, in cooperation with the movable latch bolt, releasably returns and holds the latch bolt in extended position.

Abstract: ABSTRACT OF THE DISCLOSURE              A rotary assembly, for example a sprocket wheel rigidly connected to a rotary support member, such as a hub or shaft, is produced by punching axial grooves of limited length on the outer surface of the member from one end of the member.  The material displaced from the grooves during punching flows toward the inner end of the grooves to form radially outwardly-directed lugs.  The wheel has a central axial opening formed with radially inwardly-directed projects.  When the member is located within the central opening, the projections mate with the grooves, the rear axial face of the wheel is seated against the lugs and the end face of the member projects axial-ly in front of the front face of the wheel.  The end face of the member is then deformed axially into engagement with the front face of the wheel to lock the wheel on the member.

Abstract: INVESTMENT CASTING METHOD          ABSTRACT OF THE DISCLOSURE         The specification discloses a method of manufacturing a propeller or other large casting wherein a pattern coated with a ceramic shell defining an investment mold is removed from the shell in two stages.  In the first stage a sufficient amount of the material constituting the pattern is removed by the vapour of a solvent for the material to produce a small gap between the pattern and the shell.  In the second stage, heat is applied to remove the rest of the pattern.  Because of the gap produced in the first stage, stress on, and cracking of, portions of the shell due to expansion of the pattern are avoided in the second stage and there is thereby produced a shell mold permitting production of a casting such as a pro-peller having good surface finish and precise dimensions.

Abstract: Abstract of the Disclosure A blending chamber silo for pulverized bulk material has a main chamber with an inlet in its uppermost region, and a centrally lo-cated blending chamber on the floor of the silo with bottom apertures for the influx of the material from the upper main silo chamber into it. Aeration means and air inlets are provided for the silo floor and separate homogenization means are provided for the floor of the blending chamber which operate under a pressure higher than that of the aeration means.  A relief chamber is attached to the blending chamber.  The roof of the blend-ing chamber is spaced well below the top of the silo and is of a diameter substantially smaller than the diameter of the silo, whereby the lower portion of the silo wall and the wall of the blending chamber define a semi-annular narrow space which breaks up material condensed into bridges in its downward path.  The combined function of the narrow annular space and of the two sets of aeration means of different pressures prevents the material in the annular space from densing and forming bridges and keeps the homogenizing means free of it.  Carefully determined ratios of several dimensions of the various elements are defined.

Abstract: ABSTRACT OF THE DISCLOSURE        A method is presented for cutting corrugated material into a plurality of channel shaped bodies by conveying the corrugated material along a conveyor path with guides holding the transverse edges of the material and cutting the walls of the channel shaped bodies whilst they are being held by the guide members.  The apparatus consists of the guide mem-bers on opposite sides of the conveyor extending parallel to the conveyor path for the corrugated batt material together with a saw extending transversely between the guide members.          The guide members include means for imparting movement to the batt material to allow severing by the saw, of the wall of the channels defined by the corrugations in the batt material.          This reduces waste normally encountered due to the necessity of trimming the elongated edges of the channel shaped bodies.          Time is also saved and the finished product which is semi-cylindrical, can be used in complementary pairs for insula-ting pipes for example, without further fitting and producing a jacket which has superior insulating characteristics due to efficient mating of the joining edges.
