Abstract: A sawing device is attachable to an electric hand drill. The hand drill can be operated by either alternating current or direct current, using a battery. The battery operated drill eliminates the need for electrical cords, so it can be used anywhere. The saw bar may be made of material such as plastic that requires no lubricating oil, is lighter and less abrasive than conventional metal saw bars. There is also a non-metallic insert that will attach to a metal saw bar. This insert may go into the conventional metal saw bars with the same advantages as above. The hand drill rotation is transferred through a connecting shaft to the sprocket that drives the cutting chain, which travels on a chain bar with a single sprocket.

Abstract: A hand-held tool has cutter blades actuated by a power wedge on a piston rod in an hydraulic cylinder. The hydraulic cylinder is powered by a compressed air supply through stationary apparatus containing an air-hydraulic pressure intensifier apart from the tool and connected therewith through a hydraulic line. The power wedge has inclined ramps at relatively steep angles of inclination to start closing of the blades quickly, and ramps at less steep angles to increase the force applied to the blades in cutting. An adjusting wedge stops the advance of the power wedge so that the blades do not strike each other. The tool may have an elongated rear extension with a pistol grip handle.

Abstract: A floor mounted de-watering spin chamber is connected with a kitchen disposer-grinder for de-watering and collecting ground food scraps that are suitable for garden composts. The spin chamber contains a perforated rotary spin basket and has a rigid lid with a rigid inlet tube insertable in a rigid body so that only one latch is necessary to hold the lid securely on the spin chamber. A diverter valve operated by a manual knob controls the discharge of water and solid material from the disposer-grinder selectively through the spin chamber or a drainpipe and the knob also controls a switch for an electric motor driving the spin basket. The drain pipe may also receive water and solid material from a second sink which is not equipped with a disposer-grinder and which material is not treated by the present apparatus, a baffle in a pipe connection fitting preventing such material from backing up into the spin chamber.

Abstract: Contaminated hot gases are first cooled and then the flow is divided between a plurality of identical modules for removal or contaminants. There are two stages of treatment in each module, starting with submergence of the flow under the surface of an agitated liquid neutralizing solution in a reservoir under a pair of counter rotating separator deflectors. Above the deflectors the flow is propelled upward through a venturi restrictor chamber, then into a collector pressure chamber. This completes the first stage of treatment, the second stage being the same as the first stage. Between these first and second stages the flow is passed through an electronic air cleaner. Upon leaving the second stage of treatment the cleaned gas flow joins the flows from the other modules in a fresh air distributor.

Abstract: A clamshell type loader bucket has a pair of pivotal jaws with scraping edges on the bottom of the bucket for scraping material off a supporting surface. Behind the scraping edges are brushes to sweep loose material on the supporting surface into position to be forced into the bucket when the jaws are closed together.

Abstract: An adjustable infeed ramp supports the input end of a main frame at a height to tilt the main frame to correspond to the inclination of a log in process. Pulled into the machine by a winch line, the leading end of the log is gripped by vertical feed rolls on a pair of side squeeze arms, a horizontal feed roll on a top squeeze arm and then by a horizontal top feed roll of hourglass shape just ahead of a vertical transverse shear blade. In a first operation the shear blade cuts less than entirely through the log and then moves away from the input end of the main frame, sliding the log, assisted by the feed rolls, farther into the machine. This movement pushes the leading end of the log through an adjustable splitter head assembly capable of splitting the leading end portion into two, three or six pieces, as desired.

Abstract: This method of electric welding metal band ends together comprises a fusion cycle with the introduction of inert gas, a cooling cycle with the introduction of cooling air, and an annealing cycle. The method is carried out in a fusion head having grippers to manipulate the band ends, and a control system for the grippers, inert gas, cooling air, welding and annealing currents and timing functions.

The reel, including its housing, is supported by the opposite ends of the tape.

Abstract: An elongated straight handle portion has a cylindrical plugger element on each end thereof. Each plugger element has a 45.degree. bend adjacent the end of the handle and a 90.degree. bend adjacent the distal end of the plugger element. Protruding laterally from the apex of each 90.degree. bend is a burnishing element. The burnishing element on one end of the handle is ball shaped and the burnishing element on the other end is cone-shaped.

Abstract: In the illustrated embodiments, with a bale of material compressed between upper and lower press platens an end binder moves toward one end of the bale and a back track moves toward the opposite end to apply a loop of strap around the top, bottom and ends of the bale. Two side binders move from station to station along opposite sides of the bale to apply loops of strap around the top, bottom and sides of the bale at two strap positions at each station. Each side binder has a strapping section movable toward and away from the adjacent side of the bale. Strap guide tracks on the press platens are provided with covers which confine the straps during their feed movements and prevent premature release from the tracks.

Abstract: An arcuate channel member has a detachable connection at mid length with an object to be lifted. The channel member provides a guide track for sliding movement of the lower portion of a flexible cable sling loop, the upper portion of which is lifted by a hook or grapple or the like. By sliding the loop in this guide track from time to time the lifting hook or grapple does not sharply bend the sling loop at the same point in every lifting operation, thereby greatly prolonging the life of the sling loop.
