Abstract: A protective cover for an object being transported in an airstream comprises a flexible cover member adapted to cover the object. The cover has front and rear ends, a top, two sides, and a bottom providing an opening to fit over the object. The cover member also has at least one exhaust aperture intermediate its ends with a venting member disposed over it. The bottom of the cover member is seated around the periphery of the object to reduce the airflow thereinto. The venting member has a base portion secured to the cover member about the aperture, and a body portion extending outwardly therefrom. The body portion has a closed end oriented towards the front end of the cover member and an open end disposed toward the rear end of the cover member.
Abstract: A panel assembly including two pairs of panels disposed in spaced parallel relationship lying in common planes with the coplanar panels of each pair having adjacent edges with similarly configured protrusions extending along their adjacent edges, and the protrusions on each of the panels of a pair extend towards each other. A connector is disposed between the pairs of panels and has a large recess in one face thereof which seats the protrusions on the panels disposed in one plane. The opposite face of the connector has a pair of spaced recesses therein which seat the protrusions on the panels disposed in the other plane.
Abstract: A wheel dolly for moving truck tires and drums to and from a wheel on a truck has an elongated frame for disposition on a base surface oriented in substantial axial alignment with the wheel of a vehicle. The frame has a pair of elongated and parallel spaced cylindrical members formed of sections which have telescoping adjacent ends. End braces extend across and are secured to the opposite ends of the cylindrical members. A carrier is slidably seated on the cylindrical members for movement therealong, and it has a planar central portion and angular portions depending therefrom outwardly of the frame to provide ramp surfaces. The carrier also has rollers supported on the lower surface of the central portion which are configured to seat on the cylindrical members.
Abstract: An assembly for abrasive agent recovery in water jet cutting units including a separator (4) for separating usable abrasive agent from sludge and water and a drying oven (9). A conveyor (6) follows the separator (4) for transporting the overwhelmingly usable abrasive agent separated in portions by the separator (4) and compression rollers (30) adjacent the conveyors press remaining water out of the portions located on the conveyor. The portions on the conveyor are blown by a compressed air unit (8) and a spraying nozzle into the drying oven (9), through which warmed exhaust air, further heated in the drying oven (9), flows. The drying oven (9) consists of a climbing shaft (12), closed via a heater (10) with a screen (11), an eddy chamber (16) connected to a funnel (17) to the lower end the eddy chamber (16), a line (18) from the eddy chamber (16) to a catching tank (19), and a suction connection (20).

Abstract: A pivotable door assembly has stiles and rails which are coupled by brackets having side walls defining a channel opening at the outer ends thereof. Pivot inserts are seated in the brackets on one side of said door and include a body member slidably seated in the channel and a pivot member rotatably seated in the body portion and extending outwardly of said open outer end of said bracket for engagement with the floor and ceiling. The pivot inserts include adjustable fasteners seated in the body member and cooperating with the bracket for adjusting the position of said pivot insert along the length of said channel and thereby the length of the pivot member extending outwardly of the bracket. The body member is comprised of a base element and a movable element which seats the pivot member and is horizontally adjustable. A cover is desirably snap fit over the brackets.
Abstract: A three-wheeled, battery-powered personal vehicle has a single rear wheel at the end of a swing arm pivotally supported on the vehicle chassis. A motor, also pivotally supported on the chassis, pivots about the same axis as the swing arm, pivots and powers the rear wheel through a endless drive member. The chassis is provided by a lightweight, synthetic resin tub with substantial structural rigidity. The upper body is a separate synthetic resin tub which can be nested within the chassis for shipment and readily assembled thereto at the point of sale. The assembled chassis and upper body define a generally ovoidal configuration. Batteries are carried in a front compartment and provide crash protection for frontal impacts and other batteries are located beneath the vehicle seat to provide a low center of gravity. Transversely extending chassis members provide structural stiffness as well as support elements for the assembly.
Abstract: A method for producing a ultrathin semiconducting film, utilizes a substrate with a reactive functionalized surface which is contacted with a reactant compound of a divalent and trivalent chelating metal to produce a metallo-functionalized surface. The metallo-functionalized surface is contacted with bisquinoline or a bisquinoline to produce a deposit of an oligomeric metallo-bisquinoline chelate, which is then contacted with the reactant metal compound to produce a fresh metallo-functionalized surface on the deposit. The fresh metallo-functionalized surface is contacted with the bisquinoline reactant to produce a further deposit of the oligomeric metallo-bisquinoline chelate, and these steps are repeated until a desired thickness of the deposit has been attained.
Abstract: A coin roll dispenser has a number of coin magazines each filled with rolls of coins of a given denomination and removably seated within a housing. Each magazine has a motorized conveyor adapted to receive and sequentially dispense individual coin rolls through a discharge aperture into a discharge passage which transports the coin rolls dispensed from the magazines to a receptacle from which they may be removed by a purchaser. Dispensing is controlled by activating the conveyor in selected magazines. A first sensor detects the coin rolls as they are dispensed from the magazines and a sensor in advance of the receptacle produces a total count which is compared with the total ordered and the total from the first sensor.

Abstract: An archwire is comprised of an elongated wire of nickel/titanium alloy in a generally arcuate configuration and a pair of tubular metallic sleeves in spaced apart relationship at predetermined points along the length of the wire. The sleeves are crimped onto the wire, and an upstanding metallic post is bonded on each of the sleeves. The posts are seated in the crimped area of the archwire and are secured thereto by brazing. The crimp formation is then heat set.
Abstract: A hand-held striking tool has a striking head having an eye passage of generally rectangular cross section a portion adjacent one end thereof enlarged along one transverse axis. Seated in the eye passage is an elongated handle with a metallic core rod of generally I-shaped cross section with a longitudinally extending notch in the web portion at one end providing a bifurcated end portion which has its legs inclined outwardly to a transverse dimension greater than that of the other end of the eye passage. A sleeve of synthetic resin is provided about the core rod adjacent the head and extends over a portion of the length of the eye passage. Synthetic resin fills the eye passage about the core rod.
Abstract: An above ground liquid holding tank installation includes an inner tank nested within a rigid enclosure. An open bottomed precast concrete vault encloses both the enclosure and the inner tank. The enclosure contains any leakage or spills from the tank. The vault protects the tank and the enclosure against detrimental external forces while providing access for inspection, maintenance and replacement thereof.
