Abstract: CARBON MONOXIDE DETECTION    APPARATUS AND METHOD        Abstract of the Disclosure A carbon monoxide removing catalytic material is dis-posed in one end of a first hollow column having open ends while porous inactive material is disposed in one end of a similar second column to offer substantially the same resistance to air flow as the catalytic material.  There is a bed of regenerable air-drying substance in each column between the other material therein and the opposite end of the column.  The volume and resistance to air flow of the two beds is substantially the same.  Valve means connect an air stream with said opposite end of the first column and simultaneously connect said end of the second column with the atmosphere.  Conduit means connect the other ends of the columns with each other, with an outlet port between the columns connected with the inlet of a pressure regulator.  The valve means can be reversed periodically to reverse the direction of air flow through the columns, with only part of the air stream that enters the conduit means from either column flowing to the regulator while the rest of the stream flows in reverse direction through the other column to dry the air-drying bed therein.  The outlet of the pressure regulator is connected to a carbon monoxide detector, which is turn is connected with means for indicating the amount of carbon monoxide detected every time the air flow to the detec-tor comes from said second column.

Abstract: Abstract of the Disclosure The disclosure teaches a novel noise making accessory for vehicles having spoked wheels such as bicycles or the like, and, more specifically, teaches such a noise making accessory which is adjustable to produce different sounds.  The accessory includes a plurality of fingers which can be selectively positioned to extend into the path of travel of the spokes of one of the wheels of the vehicle.          As the fingers are of different sizes, different sounds will be produced when a different one or different ones of the fingers extend into the path of travel of the spokes.  The spokes can be of different lengths, widths, thicknesses, or a combination of the above.  The objective of the accessory is to produce a motor-like sound.

Abstract: Reversible Rotary to Linear Motion Converting Device Abstract A reversible rotary to linear motion converting device which in one form comprises a screw member having multiple-lead threads, a plurality of roller members equal in number to the number of thread starts on the screw member with each of the roller members having a plurality of annular teeth of substantially equal axial pitch to the teeth on the screw member and a matching configuration to the shape of the teeth of the screw member, and an annular nut member. The roller members are mounted in rolling contact with the threads of the screw member and the annular nut member is mounted about the roller members in rolling contact therewith. The annular nut member has a plurality of internal annular grooves of substantially equal pitch and complementary shape to the annular teeth of the roller members. The nut member has substantially as many grooves as the number of teeth on each of the roller members so that when any rotational force is applied to the screw member with the nut member constrained against rotation, the total action and reaction forces on each of the roller mem-bers are substantially equal and opposite. In a further form of the invention, the multiple-lead threads are formed as internal threads in the annular nut member and the central screw member is provided with the annular teeth matching the annular teeth of the roller members.

Abstract: Abstract of the Invention A system for treating rubber tires which reduces the tires to a particulate agglomeration wherein cord and rubber matter therein can be separated. A further treating of those rubber particles reduces them to screen size. The system requires the steps of: (a) initially debeading the tire; (b) cutting the tire into chunks; (c) regulating the quantity of chunks as they pass through the system; (d) grinding the tire in a high intensity mixer; (e) passing the grind to a hammer mill to loosen the rubber and the cord from one another; (f) separating the rubber particles out in a separator, and (g) then grinding the rubber particles to a size of about 30 to 100 mesh as a final product. Oversized pieces of rubber discharged from the separator near the end of the system would be returned to the high intensity mixer.

Abstract: ABSTRACT OF THE DISCLOSURE         The machine produces a filter rod made up of a cylinder of tow and spaced apart hollow plastic tubes within the tow.  The machine includes a means for supplying a continuous tow stream to an injection station below a rotatable wheel which delivers the plastic tubes in spaced apart fashion.          Plungers on the wheel eject the tubes from the wheel and positively push the ejected tubes into the cylinder of tow at            -the injection station.  The tubes are cut from a continuous tubing by means of a cutter which is timed with respect to the operation of the machine. The cut tubes are initially pushed forward on the wheel by a pushing roll and thereafter slid backwardly by a cover so as to be properly positioned for injection into the tow.

Abstract: ABSTRACT         A surgical drain is the subject of the present invention.  A drain tube is provided with side openings into the tube, "side" being defined relative to the supporting surface.  An elongated protective shield is disposed in closely spaced relationship to the openings and extends lengthwise of the tubular member.  The protective shield inhibits the entry of loose material which would clog the openings and restrict the flow of fluid.  In one type of embodiment, the protective shield comprises a second tubular member disposed in closely spaced relationship to the first tube member.  Openings in the second tubular member face the openings in the first tubular member, the latter serving as a protective shield for the second member.  In a second type of embodiment, the tubular member is disposed in a serpentine configuration with the openings located in concave stretches along the length of the member.  The protective shield comprises a linear element extending lengthwise of the member and contiguous with the convex stretches of the member.
