Abstract: Disclosed is a method of treating waste material wherein after comminution, the relatively hard material such as glass, brick, and ceramic in finely divided condition together with finely divided soft material is separated and removed to a recirculating composter.Disclosed is a composter having a plurality of upright perforated pipes for discharge of the gaseous products of decomposition.

Abstract: A series of double pane glass panels of a standard length and width, thereby decreasing cost, are installed between a pair of parallel studs in partially upright position, with a longitudinally flanged spacer strip or strip sections attached to the inside edge of each stud for spacing the panels from a single, hollow duct-collector, or a series of connected, hollow duct-collector sections which correspond in length and width to the panels. The duct-collector acts not only as a conduit for movement of air through the device, but is also specially constructed to simultaneously transfer heat to the air. Thus, the front wall of the duct-collector is dimpled inwardly, with the outside and inside surfaces of the front wall being black and the remaining inside walls of the duct-collector sections having a bright, reflecting finish.

Abstract: The pressure of heated gases supplied by a furnace to an induced draft, rotating drum drier, through which the material being dried is moved primarily by the heated gases, is compared with the pressure of gases discharging from the drum, and the differential between these pressures is used in controlling the induced draft of the drum by decreasing the draft upon an increase in differential pressure and increasing the draft upon a decrease in differential pressure. The differential in pressure may be maintained at a value on the order of 1.2 to 1.6 inches H.sub.2 O, depending on the installation. The induced draft may be controlled at a damper between a discharge chamber for the furnace and an induced draft fan, through an electro-hydraulic actuator acting through a lever and a rod, the lever being manually settable when automatic operation is not used.

Abstract: Plastic pad at center of concave bevel of each semicircular segment maintains lateral and axial alignment when segments spread apart by pipe. In another special configuration, inside and outside segments are offset semicircles, with a greater dimension across opposed edges when abutting than middle. Inside threads of segments relieved at edges, with full threads at center and progressive decrease to each edge. Segments have cone portions opposite bevel, for engagement with concave seat of housing to tighten threads. Ring rotatable relative to housing but axially fixed has convex cone spaced from seat and engaged by bevel of segments for spreading. Resilient ring in peripheral groove of segments. Outside notches at segment edges receive housing pin or ring, to prevent relative rotation and restrain lateral play at abutting edges. Numerous variations of construction disclosed.

Abstract: The movable carrier includes a series of upright sockets corresponding in peripheral contour to the parts to be stored in upright position therein, spaced, lower base plates for supporting the sockets and an upper reinforcing plate extending longitudinally between the sockets on the respective base plates, with a cutout in the reinforcing plate for each socket having a greater lateral extent. A cross plate extends transversely of the base plate for supporting one or more additional parts. The lower end of a cylindrical part rests on or is connected to the reinforcing plate and rests in inclined position against a semicircular cup mounted on an upstanding bracket. Casters are attached to the underside of a transverse front plate and the tow handle pivotally mounted on the top of the front plate, while wheels and an upstanding handle are mounted at the rear, to permit the carrier to be pulled similar to a dolly, or tipped rearwardly and moved similar to a hand truck.

Abstract: Upper and lower rotors are offset in position, such as at an angle of 60.degree., between their centerlines, with the upper rotor having larger hammers and rotated at a lower speed than the lower rotor having smaller but a larger number of hammers. The feed is to the top of the upper rotor, and heavy interception bars extend perpendicularly to the centerline between the rotors and are disposed between the sets of hammers of the lower rotor, to prevent the entry of large objects into the lower rotor, to form an anvil against which objects on the bars are impacted by both the upper and lower hammers, with the lower hammers also "nibbling away" on the objects. A U-shaped corner formed of heavy armor plate is positioned next to the interception bars and extends between the circles of rotation of the hammer ends.

Abstract: A core barrel having a hollow cutting ring is placed within a hollow drill and connected to a coupling which permits the core barrel to remain stationary while the bit rotates and also produces pressure to force the sharp edge of the cutting ring into the earth formation, the diameter of the cutting edge and inside of the cutting ring being slightly less than the internal diameter of the core barrel. A holder for a resilient sleeve, such as woven of nylon and is bunched onto the holder with the closed end of the sleeve across the open top of the holder, moves upwardly around the core as the core barrel moves downwardly and retains the core, particularly when from a soft formation or loose unconsolidated material, in the same relative position and shape as when cut. The inside diameter of the holder is intermediate that of the cutting ring and the core barrel. An adjustment means determines the axial spacing between the cutting edge of the core barrel cutting ring and the lower edge of the drill bit or teeth.

Abstract: A stem has an upper central bore terminating a short distance from the lower end, with transverse holes for connecting the bore with the outside of the stem. Below these holes is a spiral rib, such as an Acme thread, with the lower end of the stem being beveled. A housing having interfitting threads with the stem and adjustable along the stem has a central bore terminating in a conical surface corresponding to the bevel of the stem, from which a hole extends to the lower end of the housing. A restricted hole in a passage leading to the stem, as in the ball of a ball joint, restricts flow through the head to on the order of 2 to 1.6 gallons per minute, for certain sizes of holes tested. A pair of opposed holes, spaced equidistantly from the bottom of the stem, extend through the rib area into a short counterbore at the lower end of the stem, and result in the production, at certain longitudinal positions of the housing relative to the stem, of pulsating, oscillating jets having a massage effect.

Abstract: Outlet weir of tank is lower than inlet and electrolyte is forced to flow in alternately downward and upward paths between anodes and cathodes at velocities in excess of 10 feet per minute and preferably 20 to 100 feet per minute. Cathodes (or anodes) are spaced from bottom of tank for flow underneath and anodes (or cathodes) have an upper edge of active area over which electrolyte flows, to produce upward and downward paths. Difference of electrolyte level between downward and upward flow cycles is at least 1/4 inch and not more than 6 inches, while spacing between adjacent electrodes is at least 1/4 inch and not more than 3 inches. Levels of upper edges of active areas may be consecutively lower and bottom of tank may slope downwardly to correspond.

Abstract: A gaseous source of waste energy, including heat, is passed through a gas to liquid heat exchanger and then a chiller to agitate a water bath and produce evaporation of water for cooling. The heated transfer liquid is passed through a heat exchanger to heat makeup air or the like, while, alternatively, chilled water from the chiller is passed through the heat exchanger to cool the makeup air. The source of waste energy, including heat, is normally a grease extraction ventilator mounted to receive fumes and heated air from cooking equipment. Any other source of waste energy is normally suitable, such as heated air which has risen to the upper portion of a large room or enclosure, such as an auditorium, theater, meeting hall or the like. The heated air removed from such a position is adapted in part to be recirculated, but all of it may be used to furnish heat for heating fresh makeup air. Several forms of chiller, including specialized double compartment chillers, are disclosed.

Abstract: A folding tool carrier to be attached to a tractor and to carry an array of cultivating tools or implements. The carrier includes three bars forming a central section and a wing section at each side of the central section. Each wing section is connected to the central section by inner and outer swing arms to function as a parallelogram when the wings are lifted and retracted above the central section. The central section, the wings and the arms, are placed in a common vertical transverse plane to provide for a compact unit which may be carried immediately behind a tractor.To accomplish this, the inner arms are above and the outer arms are below the central and wing sections when the wing sections are extended. A comparatively short crown bar is mounted upon and above the central section and an inner swing arm is pivotally attached to each end of this crown bar to pivotally connect with the inner end of the adjacent wing section.

Abstract: A gaseous source of waste energy, including heat, is passed through a gas to liquid heat exchanger and then a chiller to agitate a water bath and produce evaporation of water for cooling. The heated transfer liquid is passed through a heat exchanger to heat makeup air or the like, while, alternatively, chilled water from the chiller is passed through the heat exchanger to cool the makeup air. Supplemental heating, as by a furnace, or supplemental cooling, as by refrigeration, may be utilized when called for.Separate heat exchangers, as for separate areas, are alternatively supplied with heated transfer liquid or chilled water, or one or more supplied with heated transfer liquid and one or more others supplied with chilled water.The source of waste energy, including heat, is normally fumes and heated air from cooking equipment passed through a grease extraction ventilator.

Abstract: A grease extraction ventilator includes a water bath or water sprays into or through which are directed the products of the gaseous stream rising from cooking equipment and which tends to maintain an ambient temperature. This water is pumped through a heat exchanger for a portion of incoming makeup air directed into the room, the remainder of which is directed toward the intake for smoke and the like, to reduce the amount of air withdrawn from the room by the suction blower. The heat exchanger may also be utilized at a desired location, within or outside of the room in which the ventilator is installed, to heat or cool air or other fluids for heating or other purposes. Air may be directed into the upper portion of the room, such as adjacent the ceiling through a horizontal slot which causes the air to move horizontally to mix with the highest temperature air in the room and flow to portions of the room spaced from the ventilator, thereby avoiding drafts blowing against the cooking personnel.

Abstract: The invention is a single-action double-lock snap, a snap hook having a lock arm. The hook includes a shank with a hook at one end of the shank. The other end of the snap is connected to a cable or a lanyard and in use, the hook is connected to an anchor eye or the like. To avoid accidental disengagement of the hook from the anchor eye, a lock arm, or gate, is pivoted on the shank of the hook to reach across the throat of the hook to engage the point of the hook. This lock arm will thus normally lock the hook upon an anchor eye. However, the possibility exists that the hook can be accidentally opened to release the hook from the anchor eye whenever the snap is swung about while connected to the anchor eye. A detent is pivotally mounted upon the shank to bear against a seat on the lock arm whenever the lock arm is extended to close the throat of the hook. When the detent is so seated, the lock arm cannot be opened.

Abstract: A carbureting device for internal combustion engines providing pre-volatilized light gasoline vapor and a means for conserving unvaporized gasoline. An electronic pulsing circuit powers and controls the operation of an array of electric fuel pumps connected to the nozzles of a communicating array of volatilization chambers. Operating electric fuel pumps, through the connected nozzles, deliver spurts of liquefied gasoline spray mist onto ribbed inner surfaces of volatilization chambers. Liquefied mist phase of gasoline and evaporation ribs of volatilization chambers accelerate evaporation of liquefied gasoline spray mist, producing light gasoline vapor in volatilization chambers. Unvaporized gasoline drains from volatilization chambers to a fuel storage chamber and is recycled for change of phase to light gasoline vapor.

Abstract: An open ended, cylindrical barrel which carries a shell, is pushed into a housing until a single cam passes the position of a shoulder, whereupon the barrel may be twisted to lock it in position. A firing pin is spring pressed and presses slightly against the rear end of the shell, to hold the barrel in an outward position and also insure adequate impingement of the firing pin against the shell when the device is used. This slight pressure of the firing pin maintains the shell and barrel in an axially extended position, thereby insuring that the rearward movement of the barrel and shell, on impact with a shark or other menace, will cause the shell to detonate. The shell and housing are attached to a pole comprising a simple tube, the length of which may be varied, without affecting the use or operation of the device.

Abstract: The game board has playing squares, across or on some of which are placed a river or stream, a railway, mountains or other topographical features. A first set of playing pieces have indicia representing a primary function, such as a town, and a secondary function, such as one or more access roads for the town and leading to one or more of the sides of the playing piece. The first set of playing pieces is provided, on the back, with a mark which distinguishes the first set, when upside down, from the second and third sets. Pieces of the first set are placed at random upside down on the playing board. The second set of pieces have indicia representing a function correlated with the function of the first set of pieces, such as roads extending from the center to one or more sides of the playing piece, and are playable in abutment to pieces of the first set.

Abstract: The free platen has a weight inside to produce inertia against movement by typing, as well as extensible end pieces for extension to correspond to lateral extension of a paper guide. An adjustable end plate at each end of the typewriter frame carries a lower supporting and positioning roller which engages the platen at a point forwardly of the vertical centerline thereof and a rear supporting and positioning roller which is essentially opposite the point of impact of the typing element and engages the platen at a point below its horizontal centerline. The platen has a pair of ring gears having an outer diameter less than the thickness of the elastomer covering the platen between the gears, with a short section of elastomer beyond each ring gear. The ring gears are engaged by a gear of a pivoted indexing device, which gear engages the platen ring gear when the respective indexing device is in down position. The ratcheted indexing device is actuated by conventional levers, arms, etc.
