Abstract: An extruder for delivering foamed glue from a foamer selectively to a plurality of spaced apart outlet orifices for extrusion onto a substrate surface and to bypass passageways for diverting the foamed glue to a defoamer for subsequent return to the foamer, is formed of three elongated flat blocks secured together releasably in face-abutting relationship. The surfaces of the outer, inlet and bypass blocks facing the center coupling block are recessed to provide a plurality of passageways all of which extend substantially equal distances from inlet and bypass ports in the inlet and bypass blocks, respectively, to a plurality of coupling ports in the coupling block. An air pressure operated selector valve in the bypass block is operable to communicate the coupling ports selectively with the bypass passageways for bypassing foamed glue to the defoamer and with the outlet orifices for extruding foamed onto a substrate surface.

Abstract: Spaced apart and covered Petri dishes are moved continuously toward a pair of spaced feed nozzles while the covers engage a ramp and are tilted upward away from the dishes to provide a space for reception of the feed nozzles. A photoelectric cell detects the passage of the dishes beneath the feed nozzles and controls the feeding of bacterial culture growth medium alternately from the nozzles into the dishes as the latter move continuously past the nozzles. The covers are replaced over the dishes after filling.

Abstract: A conventional ski boot is provided with a walking attachment configured as a removable, curved sole arranged with toe and heel straps configured to be clipped over the front and rear ledges of the boot, the deepest portion of the curved sole being located under the ball of the foot for allowing the foot to rock rearward, thus enabling the leg to be straightened at the knee for normal walking.

Abstract: An assembly of top and bottom plates spaced apart vertically by peripheral and intermediate spacer bars forming a shelf of freeze drying or other processing equipment, is held together on a movable base support by peripheral clamps mounted removably at selected positions on the base support. A hollow framework carriage is mounted on the base support for movement above and relative to the shelf assembly and it supports a pair of elongated, laterally spaced clamp bars for retractable movement toward and away from the base support for releasably clamping therebetween interposed portions of the shelf assembly. A laser welder then is moved relative to the clamp assembly to weld the components together in the clamped areas. Upon completion of the welding operation, the clamp bars are retracted and the framework moved over the base support and assembly to the area next to be welded, whereupon the clamp bars are extended into clamping position and the welding operation is repeated.

Abstract: A hollow, tapered master shaft is made of glass fiber cloth impregnated with synthetic polyester resin and has a length of about 55 inches, a wall thickness of about 0.03-0.06 inch, a butt end outside diameter of about 0.80-0.88 inch and a tip end outside diameter of about 0.35-0.42 inch. A golf club shaft is made from this master shaft by cutting away a portion of the length of the master shaft, from one or both ends, to derive the desired length, flexure and butt and tip dimensions.

The assembly comprises a vertically extensible main frame secured to the lift truck carriage, the frame pivotally supporting a first pair of tiltable container lifting beam sections for adjustment between an operative position in which they are in longitudinal extension, for engaging an empty cargo container for transport, and an inoperative position in which they extend along the lateral sides of the lift truck in order to allow for increased manueverability of the vehicle while not functioning in the transporting of cargo containers, and for operation of the lift truck in conventional uses and in confined spaces.

Abstract: A portable vehicle servicing lift includes a trailerable frame which pivotally mounts a pair of transport wheels arranged to be moved between an extended transporting position and a retracted position in which the frame connected thereto is lowered to the ground or other support surface. The frame also mounts a pair of vehicle ramps adjacent one end by a fixed fulcrum associated with the frame, and at the opposite end by a hydraulic piston-cylinder pivotally interconnecting the ramps and the frame for movement of the ramps about the axis of the pivot fulcrum. The frame includes a pair of trolley rails mounted to the frame between the transport wheels, the trolley rails configured to guidingly support a chair assembly and other equipment associated with automotive repair for movement along the full length of the frame.

Abstract: The wheeled frame remaining after removal therefrom of the detachable cargo container, is gripped by clamping mechanism of a carrying unit mounted on a tractor or lift truck, then elevated above the ground and pivoted from its normal horizontal disposition to vertical position, and then transported to a multiple storage unit where it is deposited and retained in said vertical position removably in one of a plurality of compartments making up the storage unit. A plurality of such wheeled frames may be stored in this manner by deposit in successive ones of the compartments, and they are removed from the compartment in the reverse order of deposit.

Abstract: One of a pair of panels to be joined together is provided with a longitudinally extending panel support groove cut parallel to an edge of the panel, and a connector mounting slot is cut from the edge of the panel inward, perpendicularly crossing said groove, terminating a spaced distance inwardly of the groove. The second of the pair of panels incorporates a bore arranged to be a spaced distance above, and aligned with said mounting slot when the panels are in position to be joined together. A panel has a connector body mounted on a base slidably engaging said mounting slot, and a locking pin on the connector body is arranged to intercept the bore in the other panel, thereby releasably securing the second panel to the first panel by means of the connector.

Abstract: The wheeled frame remaining after removal therefrom of a detachable cargo container is gripped by clamping mechanism of a carrying unit mounted on a lift truck, then raised above the ground and pivoted from its normal horizontal position to a vertical position for transport to a multiple storage unit. The clamping mechanism is mounted for movement along an elongated boom the inner end of which is mounted on the vertically movable carriage of a lift truck for pivotal movement of the boom between horizontal and vertical positions.

Abstract: An elongated hollow housing is attached to an inert gas arc welding torch in a position extending rearwardly of the electrode parallel to and trailing the direction of movement of the torch during welding, and a source of inert gas is coupled to the interior of the housing. The housing serves to distribute inert gas over a sufficient length of produced weld extending from and trailing the puddle of molten metal that said length of weld is protected with inert gas until it is cooled to a temperature at which is not adversely affected by atmospheric oxygen and nitrogen. The housing may be completely open at its side facing the work to be welded, or said side may be formed as a perforated wall. Also, said side may be contoured to substantially match the contour of the work to be welded.

Abstract: Each cylinder of an internal combustion engine is provided with a reciprocative piston and a combustible fuel intake port controlled by an intake valve. A steam generation chamber communicates with the cylinder through a steam inlet port controlled by a steam inlet valve which is opened by steam pressure in the generation chamber. The generation chamber also communicates with a combustible fuel exhaust pipe through a combustible fuel exhaust port controlled by a fuel exhaust valve the opening of which is also accompanied by opening of the steam inlet valve. The steam generation chamber also communicates through a water injection valve and, preferably, a heat exchanger associated with the exhaust pipe, with a source of water under super-atmospheric pressure. A steam exhaust port, controlled by a steam exhaust valve, also communicates the cylinder with a steam condenser the outlet of which communicates with a supply reservoir for the water source.

Abstract: A rod of dielectric material of uniform diameter of about 9.5 mm and about 1.2 meters in length supports about 8.4 meters of insulated copper wire of about 1.6 mm diameter coiled about the rod to form adjacent one end a base coil of at least three tight turns and at the opposite end five tight loading coils each about 5.5 centimeters in length and spaced apart from each other about 6.4 mm. A tight trim coil is spaced about 6.4 mm from the outermost one of the loading coils and contains a number of turns 6.4 mm from the outermost one of the loading coils and it contains a number of turns selected to optimize the standing wave ratio of the adjacent coils. The length of wire between the base coil and innermost one of the loading coils is coiled about the rod in single wide turns to minimize radiation therefrom. Shrink tubing overlies and conceals the wire.

Abstract: The Q-switched laser gating pulses of an acousto-optic Q-switch are synchronized electrically to the phase of the RF signal driving the Q-switch by applying the RF oscillator output signals to the clock input of an integrated circuit D-type flip-flop and the laser gating pulses to the D input of the flip-flop, whereby the leading edge of each output gating pulse from the flip-flop always occurs at a particular place on the RF waveform. In another embodiment, the RF signals are synchronized to the phase of the gating pulses by applying the output of a repetition rate oscillator to the RF oscillator.

A brush is mounted to the rear edge of the body for sweeping contact with a surface when the sweeper is rolled over the surface.

Abstract: System of testing and sorting according to tested ranges of values of miniature electronic capacitor and resistor units. A planar carrier with rows and files of openings, loaded with such units, is disposed in an oblique plane to retain the units in place. The carrier is moved in a stepped manner past an electrical testing station and past a series of sorting stations. At the testing station, a file of probes is brought into electrical contact with one end of a set of electronic units in each file. A metal ply laminated in the carrier contacts the other end of the set of electronic units. A bridge network makes measurements by connecting to the file of probes and to the metal ply. A receptacle is disposed at each sorting station. As each file of electronic units passes the receptacles, the units are selectively deposited in the receptacles, by air jets, according to tested ranges of values.
