Abstract: An attachment for motor powered drills for accurately positioning drill bits when holes of regulable depth and angle are to be drilled in a work piece. An open-centered base for contact with the work piece provides journal supports for paired rotatable trunnions that may reciprocally receive guide rods disposed above the base and at right angles to said trunnions. Paired guide sleeves of a frame attached to the drill motor and disposed parallel to the axis of the drill reciprocally receive the guide rods, and the drill and its bit are, accordingly, movable along the guide rods to cut a desired hole in the work piece. Index means and detents facilitate varied angular positionings for said trunnions and guide rods whereby holes that are angularly disposed with respect to the work piece may be drilled. The guide rods may be extended through the base to provide accurate centering of drilled holes, and a separate jig or vise is provided that holds the drill attachment and drill, etc. in adjusted lateral positions.

When in use, hair rollers or curler implements that may be of varied size are disposed in the vertically disposed top component within chutes that have guide dividers to prevent clogging of the chutes and that assure one-at-a-time dispensing of the rollers. The top is disposed in an essentially inverted horizontal position when the case is closed to prevent the escape of rollers. Separated compartments are provided in the base for the reception of additional tools, liquids, towels and other hairdresser's paraphernalia.

Abstract: Instrument apparatus and method for the cyclically concurrent display of the time related transitional characteristics of a plurality of samples, at least one of which may be a laboratory standard of known value, or all of which samples may be unknown. Separate electrical signals derived as the samples are simultaneously activated, exposed, treated, analyzed or observed are gated by multiplexing circuits on a split time basis that may allot equal or varied time periods for the separate samples. The strength of the signal from the samples may be separately or cooperatively adjusted to enhance comparison or differential features as the signals are delivered to display components for study or recording.

Abstract: An electric switch and signal output device for use in fluid systems. A light source and photosensitive pickup are disposed in aligned positions in a cross bore of the switch body at opposite sides of a main bore that reciprocally receives a piston element. If fluid subjected to differential pressures is introduced to the main bore at one side of the piston or if fluid is introduced to opposite sides thereof, pressure pulses or changes in differential pressure in the fluid system cause movement of the piston away from or toward an interfering position with respect to the light path between said light source and pickup. Incident light at the pickup, which may be a photocell resistor, provides an output electrical signal change that is usable for control, position indicating, counting or logic purposes. The actuation sensitivity is changed by use of different weight pistons and/or by use of adjustable resilient means.

Abstract: In a four stroke cycle reciprocating internal combustion engine, four dual functionable combustion chambers and two power trains to crankshaft are comprised of a single stationary cylinder encasing two quadruple faced rotor-reciprocative pistons, further encasing a rotatable intake-exhaust manifold geared to an external rotatable crankshaft. The crankshaft is connected by connecting rods to driving arms on external extensions of the two pistons.Two such units connect to a common crankshaft to comprise an eight combustion chamber engine.Upon each crankshaft half turn stroke the two pistons of a unit and associated intra-engine power trains to the crankshaft move simultaneously in opposed directions to expand two chambers for intake and combustion and to contract the other two for compression and exhaust functions.

Abstract: A circuit and apparatus combination for maintaining a balanced or regulated operational condition in test apparatus that includes mechanical drive and sensor elements as the sensor is exposed to the changing conditions experienced in a test sample or a sampled environment. The circuit automatically drives mechanical elements of the system at a resonant frequency or at other prescribed conditions with voltage changes at an output section of the circuit being indicative of changes in the sample tested or in the sensors environment. Drive elements of the circuit are powered by a drive voltage to cause movement of the sensor and the changing power thus used is evaluated and cancelled out, while a separate input or response voltage that is derived from the resulting movement of the same drive elements is introduced to an Operational Transconductance Amplifier together with an input control current likewise derived from such response voltage.

The platform has a plurality of can receiving base edges or receptacles to receive and support cans of different size. The bottom rims of the cans are securely held by protrusions at least one of which is flexibly mounted to facilitate release of the cans from the platform. The platform, removable hooks, brace arm and lock bar are cooperatively designed for compact storage and shipment.

Abstract: A holder for the convenient dispensing of rolled paperr towels and the like. A standard of size to closely engage the interior of the tube core for the roll of paper extends outwardly from a base support that is adapted for engagement with various support surfaces disposed near points of use for the towels. The hollow base has widely spaced apart sidewalls that enclose a centrally disposed suction cup with edges of said sidewall being selectively held in contact with the support surface by vacuum influences induced by said suction cup to provide stability for said holder, its standard and any roll of paper towels disposed thereon. A mechanism on said standard that is interconnected to said suction cup induces or relieves the vacuum influences when the holder is being placed or removed.

Abstract: Fastener elements are provided for use at selected positions or openings in a composite truss system that is to be used in building construction for form work or permanent installation. The combination truss bolt drift pins proposed herein have shanks of constant cross-section for driven interfit with predrilled holes of truss elements to be joined. The shanks of the bolt pass completely through the elements being joined, and threads of lesser diameter than the shank extend outwardly from the joined elements. The fastener nuts for use with the bolts have a recess at the intended interface with the truss elements that undercut the threads thereof and that is of a size to accommodate a step shoulder of the shank thus assuring full contact of the element holes and the shank component. A drift pin extension for the bolts is of tapering contour from a larger diameter corresponding to the shank diameter to a lesser size providing easy introduction into holes intended for mating alignment.

Abstract: A dry milling process for separating a mineral values bearing component from the sand grains or gangue materials of sedimentary formations. The ores are crushed, ground and screened until the bulk of material is of a size corresponding to or slightly larger than the predominant size of the sand grain particles embedded in the deposit. After or before complete sizing the ore charge may be heated and dried if required before being directionally impelled and abraded. Further applied forces and guidance components distribute the materials to provide a curtain type flow pattern of directed movement that may be at least partially dependent on a primary fluid flow pattern.
