Abstract: The print screen frame tensioning system, generally rectangular in shape and fabricated from extruded rectangular tubular rails, when assembled, each side rail of the frame has a longitudinal one way channel, circular in cross sectional area, formed in each of the tubular rails for substantially the length of the tubular rails for receipt of a locking rod, the locking rod being axially serrated in order to accept a matching internally serrated standard wrench socket and the longitudinal channel being axially serrated, each locking rod having an additional internal tensioning fitting formed on both of its longitudinal ends for separate lateral tensioning.

Abstract: A hybrid engine including an electric motor, a rotary internal combustion engine, and an electric generator incorporating a clutch and translator unit to drive the generator at a ratio greater than 1:1 during vehicle slowing and at a 1:1 ratio rate at other times in providing increased braking and fuel efficiency—along with a programmable central control module and vertical control lever in effectuating steering and vehicle operation without the use of a steering wheel or foot gas and brake pedals.

Abstract: An improved indexing device for generating a smooth and controlled rotary motion where double rotary cranks having slide members coupled to corresponding slide guides arranged in orientation parallel to the plane of rotation of the rotary cranks are provided. Each slide guide is attached to a trolley movable in a direction transverse to the axis of the slide guides. A linear gear rack is mounted on each trolley in parallel to its sliding motion and are opposingly configured across a rotary gear member. The gear member drives a positive locking clutch which is entirely self contained within the indexer assembly itself and requires no operator or external control. The clutch function is accomplished automatically when appropriate during the indexer cycle. During stationary periods, the output of the indexer is locked preventing movement of the indexer and providing unique stability to the device.

Abstract: Disclosed is a rotary engine comprising a rotor, a plurality of pistons angularly mounted in the rotor, an actuator mounted for eccentric rotation relative to the axis of rotation of the rotor, a blower, a transverse actuator pin connecting each piston to the actuator, and a plurality of fixed pins connecting the rotor to the actuator. The fixed pins are mounted on the rotor, pass through clearance holes in a rotor disc which acts as a blower, and carry extension gears which mate with internal gears mounted in the actuator. Accordingly, rotation of the rotor causes rotation of the blower and of the actuator.

Abstract: Disclosed is an infrared dryer which comprises (1) at least one infrared heater in a heating chamber, (2) a pair of mutually parallel air troughs which guide ambient air from an intake end of the dryer, along the top of the dryer, and empty air into a collector box of the air plenum at the downstream end of the dryer, (3) a header disposed above the heating chamber and ported to permit air from the header to be directed onto objects in the heating chamber, and (4) means for recirculating air from the heating chamber into the header.

Abstract: Disclosed is an infrared dryer which comprises at least one infrared heater and a pair of mutually parallel air troughs which guide ambient air from an intake end of the dryer, along the top of the dryer, and empty air into a collector box of the air plenum at the downstream end of the dryer. One of the air troughs runs along the top of the infrared heater and is ported to accept effluent air from the heating chamber, and the other of the air troughs extends along the upper surface of the dryer and serves to continually cool the upper surface or cover of the dryer.

Abstract: A solar energy unit comprising a housing adapted to be mounted on the roof of a building or otherwise suitably supported. The housing has a central cavity which contains a reservoir for a heat absorbing liquid. A heat exchanger containing a circulating heat exchange fluid is immersed in the heat-absorbing liquid. The heat exchange fluid circulates to areas to be heated. A transparent dome covers the upper end of the housing and the cavity and is provided with prismatic facets on its inner surface to magnify the sun's rays and to focus or concentrate the rays on the heat-absorbing liquid. The dome is substantially hemispherical and will receive the sun's rays regardless of the position of the sun relative to the housing.

Abstract: A device for maintaining a predetermined alignment of a running web and more particularly maintaining the alignment of the belt of an endless conveyor comprising an idler spool over which the web or belt passes and which is laterally movable relative to its supporting framework. Means are provided for lifting one end of the idler spool and lowering the other in response to the lateral shifting of the belt and spool from a predetermined aligned position to cause the spool and the belt to again seek the predetermined aligned position.

Abstract: A rotary internal combustion engine comprising a cylindrical housing comprised of an annular intermediate member and a pair of end plates, one on each side of the annular member, and defining an enclosed, generally cylindrical, rotor chamber. A shaft is journaled in the end plates and extends through the chamber. A rotor is fixed to the shaft for rotation therewith in the rotor chamber. The rotor chamber is concentric with the housing, while the rotor and shaft are concentric and eccentrically disposed relative to the chamber and housing. Pivoted vane elements are mounted on the periphery of the rotor and are biased into engagement with the annular wall of the rotor chamber and sequentially form intake, compression, combustion and exhaust chambers between the rotor and the annular wall. The vanes include resilient elements having bent-back portions which engage the annular wall to provide seals between the sequentially formed chambers.

Abstract: A mechanical squeegee apparatus directed for use with and mounted on a stencil screen printing device. The apparatus includes a longitudinal support bar and a lateral support bar which is mounted for movement along the longitudinal bar and which extends transversely thereof and over said screen. A squeegee is mounted on the lateral bar for free movement along its length and for substantially free rotational movement relative to the lateral bar on an axis vertical and perpendicular to that of the lateral bar. The free lateral movement and the substantially free rotational movement allows the squeegee to be used to sweep ink from the side edges of the screen toward the center without the use of an intermediary device such as a hand-held card or scraper.
