Abstract: A ferromagnetic shunt is pivotally mounted to a housing to form a pendulum which swings between a reed switch and a magnet. As long as the shunt remains between the reed switch and the magnet the reed switch remains open. The shunt is held or biased between the magnet and the reed switch by the force of the magnetic attraction between the shunt and the magnet. The mass of the shunt acts as both a tilt sensor which responds to gravity and an accelerometer sensitive to crash-induced accelerations. The reed switch, magnet and shunt are mounted in a housing which positions the reed switch and magnet and controls the maximum range of motion of the shunt. The magnet is located between two sidewardly spaced pendulum arms, which allow the shunt to swing out from between the reed switch and the magnet in two opposite directions.

Abstract: A regulated and effective means of exercising cats, which also serves as a cat perch and central cat feeding and hygiene station has a frame constructed of conventional dimensioned timber which supports a horizontal perch in cantilever fashion. An inclined treadmill with a closed loop belt encircling a plurality of rotatable rollers extends between a support surface and the perch. The cat makes his way to the perch by climbing the treadmill, which may be set at varying inclinations to suit the cat's weight and strength to obtain the desired treadmill time for a particular perch entry. The treadmill and the perch are covered by bent sheets of plastic, which confine the cat and require the cat to traverse the treadmill rather than jumping to the perch. The perch may be fitted with a pivotable door to temporarily retain the pet within the perch enclosure for limited times.

Abstract: A clamping bar assembly for a bar screen with a plurality of screen bars and in which at least one leg extends downwardly from each bar and a bar support beam extends below the bars. The bar of this invention includes a plurality of spacers positioned on the support beam between neighboring bar legs. The spacers are clamped together with the bar legs by a first flange which is fixed to the support beam and which has an upwardly extending portion, and a portion which extends inwardly above the beam to engage the spacers. A second flange, removably fixed to the beam, has an upwardly extending portion, and a portion which extends inwardly above the beam toward the first flange so that the clamped spacers and bars are restricted from vertical displacement by the first and second flanges.

Abstract: A dryer section in a papermaking machine has two reversing rolls to form a pocket between each pair of dryers in a dryer tier. The first reversing roll is a vacuum roll and the second reversing roll is a grooved roll. A blow box is disposed between the two rolls, the blow box provides suction for the grooved roll and provides vacuum which restrains a web on the dryer fabric as it travels between the first and the second rolls. The blow box also provides a supply of make-up air which extends in a cross machine direction along the pocket formed by the two reversing rolls. The blow box also supports a pivoting foil which is positioned against the dryer fabric as it moves from a first dryer, towards the first reversing roll. The foil defines a region of low pressure which restrains the web as it travels between the first dryer and the first reversing roll.

Abstract: A quick-assembly corrugated box has an automatic bottom panel which extends from a side panel, and has two converging reverse-scored fold lines which extend outwardly from the side panel. End flaps are folded up from the automatic bottom panel and are adhesively connected to the end panels to form double ply side walls. One of the end flaps has a diagonal fold line, with portions of the flap above the diagonal fold line only being adhered to the end panel. The angles of the reverse scored fold lines are selected to allow the automatic bottom panel to be deployed from a folded position alongside the side and end panels to an assembled position perpendicular to the side and end panels, simply by displacing one side panel with respect to the other. Substantially increased stacking strength is provided by inserting right-angle corner pieces in reinforcement-receiving pockets defined between the edges of the end flaps and the end panels.

Abstract: For distributing stock evenly across the face of a tube bank in a papermaking machine, the stock supply header has an increasing change in cross-sectional area per unit width traveling from the inlet end to the recirculation end of the header. The header top wall converges toward the bottom wall, while the rear wall converges toward the front wall. The change in cross-sectional area down the header from the inlet end to the recirculation end is thus closely matched to an ideally parabolic shape.

Abstract: Batteries are displayed for consumer purchase in a package which provides a means for spacing an electronic article surveillance sensor from the batteries contained within the package. By spacing the sensor away from the metal case of the batteries the interference typically caused by metal in close proximately to an electronic article surveillance sensor is eliminated. Two ways of accomplishing the spacing of the sensor from the batteries are disclosed. The first is a strip of cardboard placed between the surveillance sensor mounted on the side of the box and the batteries. The second is a specially designed box which has a box panel which divides the box into two compartments: one to hold the batteries and a second which creates a space between the batteries and the side of the box on which a surveillance sensor is mounted.

Abstract: Two racks of parallel spaced bars are supported for oscillatory motion from overhead drive shafts having eccentric cam surfaces. A first drive shaft is driven by a belt connected to a motor, and a second shaft is connected to the first shaft for synchronized movement by a rigid link. The bars are clamped to bar support beams without the need for bolts to extend through individual bars. The support beams are connected by side frames to the eccentric cam surfaces.

Abstract: A compound of the formula ##STR1## where R is a solid support; R.sub.1 and R.sub.2 are alkyl, unsubstituted alkyl, or phenyl, and where R.sub.1 and R.sub.2 can be the same or different, for use in solid-phase synthesis.

Abstract: A launch vehicle which employs a rotor similar to a helicopter. The vehicle has a four bladed rotor which is mounted on the vehicle body. The body of the vehicle includes propellant tanks and a payload compartment contained within an integral aeroshell. Rocket engines used to propel the vehicle into earth orbit are mounted at the ends of the rotor blades. The engines are connected by propellant feed lines to a propellant transfer hub surrounding the axis of rotation of the rotor. Propellants are fed from an oxidizer tank and a fuel tank through a propellant transfer coupling to oxidizer and fuel lines which extend to the engines at the rotor blades ends. The rotor blades incorporate air foils. To operate the vehicle the vehicle is positioned on a concrete or asphalt pad and fueled with liquid oxygen and kerosene. The engine are positioned tangent to the blade paths and ignited.

Abstract: A pre-metering rod is located between a coating applicator and an air knife, and replaces the smoothing roll in some existing air knife applications. The pre-metering rod consists of a small diameter rod of about one and one-half inches in diameter that rotates at 10-500 rpm against the direction of the coating layer on the web. The web is wrapped around a portion of the circumference amounting to about twenty-five degrees of the rod's surface as it travels over the rod. The rod is supported in a rod holder supported on a support beam. Actuators move the support beam away from the web for threading and maintenance, and towards the web to engage the rod with the web. The combination of the rod diameter, the amount of wrap on the rod, and the speed of the rod rotation determine the amount of pre-metering of the coating, which determines the thickness of the coating layer on the web that is presented to the air knife section. As a result, the thickness of the coating layer can be decreased.

Abstract: A mixture of air and paper stock made from recycled paper from which the ink particles have been chemically released is injected into a cylindrical processing vessel. Added surfactants create a foam from the air as it rises through the stock and cause the ink particles to adhere to the air bubbles, resulting in a foam containing a concentrated fraction of the ink particles with some included fibers. The foam rises to the top of the vessel, and carries with it ink particles. Additional air injection ports can be used to increase the amount of foam generated and the amount of ink removed. Flow of stock and foam from the vessel can be controlled by adjusting valves on the stock and foam outlets. Flotation sensors allow the foam head to be maintained at the stock level by controlling the rate foam is withdrawn through the foam outlets.

Abstract: The window sash of this invention employs strips of extruded plastic materials which are connected together by mechanical fasteners into an inner sash. The inner sash has barbed protrusions formed on the interior and the exterior which define interior and exterior channels into which wooden or metal trim members may be engaged in snap-fit relation. In operation, individual trim strips are first combined with interior sash elements. These sub-assemblies are then joined with L-shaped injection molded keys. The trim members, plastic keys, and plastic inner sash are then clamped in a frame and stapled together. The exterior sash trim or ring is assembled separately and brought together for assembly with the inner sash. A mastic adhesive is applied to the inner sash, a thermopane window light assembly is disposed on the adhesive, and a bead of adhesive is applied to the rabbet of the exterior ring which is then press-fit into engagement with the inner sash.

Abstract: The headbox apparatus of this invention contributes to the production of a paper web of uniform fiber orientation by controlling the edge flow of stock into the headbox nozzle through adjustable valves positioned in edge tubes in closed loop with a fiber orientation sensor. At the same time that fiber orientation is being control through adjustable valves position in the edge tube, basis weight of the web being formed is controlled by a stock dilution systems and an adjustable slice lip, in closed loop with a basis weight profiler sensor.

Abstract: A air density separation has a vertical air separation chamber that opens downwardly to allow rejected material to fall out the chamber through the open bottom. The air density separator is configured to recirculate the air and entrained fines, and so minimizes emissions and costly air treatment processes. The air separation chamber is connected by a first duct to a cyclone. A fan is positioned adjacent the lower end of the air separation chamber, and draws air through a second duct out of the cyclone for reintroduction into the air chamber. The fan by way of the cyclone draws air through the first duct from the air separation chamber. The fan exhausts into the vertical air separation chamber below the material infeed through a plenum. An oscillating screen composed of bars extends into the separation chamber of the air density separator and is used to disperse material into the separation chamber.

Abstract: Two twin-sheet thermoformed thermoplastic sleeve halves engage within peripheral grooves in an underlying pallet and an overlying cover. Each sleeve half has a full wall which is connected by integrally thermoformed hinges to two partial walls. The integral connection between the sleeve walls gives advantageous rigidity to the pallet sleeve assembly, while the hinging of the walls allows economical manufacture and low volume flat storage of the sleeve halves in a knocked-down configuration. The hinges preferably have non-specific hinge axes, thereby providing long hinge life, impact resistance, and ease of operation. Vertical substrate tubes are totally encapsulated into each sleeve half to carry loads from a supported loaded pallet sleeve assembly. To effectively transfer the loads from the cover to the sleeve, sinuous transfer ridges are molded on the sleeves above and below the vertical substrate tubes.
