Abstract: A waste material classifier apparatus which employs a rotary trommel for stirring up the waste material in an air stream so that the conglomeration of waste is easily sorted into dirt and small particles easily sifted through the trommel pores, with air sensitive paper and plastic carried out to a collection zone and large, heavy metallic objects thrust out of the trommel and run through both a magnetic separator and an induction conveyor head stock to sort out the metallic trash according to its magnetic and non-magnetic characteristics.

Abstract: A double row tapered roller bearing, which has the capacity to produce a pulsating electrical signal, the frequency of which reflects angular velocity, includes an outer race having a pair of tapered raceways that are presented inwardly, two cones, each having a tapered raceway that is presented outwardly toward a different raceway of the outer race, and tapered rollers arranged in two rows between the raceways of the outer race and the cones, with the small ends of the tapered rollers in each row being presented toward space between the two rows. The outer race has an oblique bore which opens into the space, whereas one of the cones has an axially directed seat which extends into the space. The oblique bore contains a sensor while the axially directed seat has a target wheel fitted over it, and the target wheel has an oblique operative surface that is presented opposite the inner end of the sensor, there being a slight gap between the two.

Abstract: A control device, which is interposed between a modulating motor and a valve, includes a control arm which is mounted on the shaft of the valve and a roller follower that is on the arm. In addition, the control device includes a bracket which is mounted on a fuel line adjacent to the valve, a cam which rotates on the bracket about an axis that is parallel to the shaft and an operating arm which rotates with the cam and is connected to the modulating motor, so that the modulating motor moves an air damper and cam in unison. The cam has an arcuate element which curves eccentrically about the axis of rotation and screws which are threaded into the arcuate element such that their ends form a cam profile. The roller follower bears against this profile, riding over the ends of the screws as the cam rotates.

Abstract: A pizza dough shell container which makes up into a package having a plurality of similar containers supporting a single pizza dough shell in each container so that by forming a package of many containers the pizza dough shells are protected during transit to a place of sale and at the same time the shells are free to relax and undergo some shrinkage but are free to be removed from the containers to supply the demand.

Abstract: A small building is constructed from components erected on a non-progressive basis. Among these components are base plates laid out in a rectangular configuration such that the ends of the plates form corners, posts which extend upwardly from the base plates at the corners as well as between the ends of the base plates, and roof caps which rest on the posts and support a roof. Each post includes a stud having a web which extends generally transversely with respect to the base plate and roof cap between which its post is located and flanges which project from the web generally parallel to the base plate and roof cap. Each post also has a stud cover having a center wall, a positioning groove along the center wall, and flanges projecting beyond the center wall. The positioning groove of the stud cover receives the web of the stud, and screws pass through the center wall of the stud cover and thread into the web of the stud, thus securing the stud cover to the stud with their flanges parallel.

Abstract: Both aluminum scrap covered with a volatile coating and a heated airstream having a low oxygen content pass through a kiln where the airstream causes the coating to volatilize. The temperature of the airstream, where it enters the kiln, is maintained essentially constant, slightly below the melting temperature of the aluminum, and likewise the temperature of the airstream is maintained essentially constant where the airstream leaves the kiln, this being achieved by varying the mass flow of the airstream to compensate for variances in the nature and mass of the aluminum scrap within the kiln. Beyond the kiln the airstream enters an afterburner where it is heated in the presence of sufficient oxygen to effect combustion of the volatile components of the coating. The airstream then passes through a heat exchanger and back to the kiln. The mass flow within the kiln is controlled by diverting some of the airstream upstream from the heat exchanger or by varying the speed of the fan which creates the airstream.

Abstract: An animal operated insecticide spray delivery system operably enclosed in a barrel housing having an access opening to a feed source inside the barrel. The barrel is suspended in space such that the animal must thrust the head into the access opening to operate the spray delivery system. Should an animal butt the barrel, it will simply swing out of the way and in doing that it will lift which is not the habit of an animal to lift its head.

Abstract: A contoured cellular cushion has a base and flexible cells, which are inflatable, projecting upwardly from the base. The base is rectangular and the cells are arranged in front-to-rear and transverse rows upon its. Moreover, the cells are preferably organized into two zones--an outer zone and an inner zone--with the cells of each zone being interconnected amongst themselves, but not with the cells of the other zone. The outer zone includes long cells which lie along the sides of the base in side sections and also in an abductor section between the side sections near the front margin. The shorter cells of the inner zone occupy the remainder of the base and produce a depression between the side sections and behind the abductor section of the outer zone, and troughs on each side of the abductor section.

Abstract: A tractor-trailer combination carries cargo holders which extend across the cargo compartment of the trailer, bearing at their ends against the trailer side walls to thereby confine cargo when the compartment is less than fully filled. When not in use, the cargo holders are stored in a rack which may be attached to the back of the tractor cab or to the underside of the trailer bed. The rack includes a pair of spaced apart carrier bars having notches which receive the cargo holders and retaining arms which close the ends of the notches in the bars and retain the holders in those notches.

Abstract: The invention herein is concerned with not only limiting the velocity of packages on a downwardly inclined conveyor trackway, but effecting a cyclically operable system of brake assemblies that not only brake the flow of packages down the trackway but effect reversal of groups of rollers in the trackway for short periods of time so that gaps are created between packages as they accumulate at the end of the trackway so that the pressure between packages is redudced so as not to damage the contents. The brake assemblies are distributed in adjacent series along the trackway and operate in association with different groups of rollers and in timed cycles so that packages are prevented from developing a free or unretarded flow under gravity influence.

Abstract: A transparent composite material, which may take the form of a plate, includes a polymeric matrix and glass fibers embedded within the matrix. The polymer of the matrix and the glass of the fibers are transparent and have substantially the same index of refraction. A bond exists between the glass of the fibers and the polymer of the matrix. The composite may be formed by immersing the fibers in a monomer and then curing the monomer to a polymer.

Abstract: A dry wall tape having a curved center section, reversely curved intermediate sections and outwardly tapering wings terminating in a thin edge. The tape can be used on inside and outside corner joints to obtain a straight line. Preferably the tape has triangular cut outs in the wings and removable end strips along the outer edges of the tape to facilitate taping of curved corners.

Abstract: A unitary bearing assembly having two rows of rolling elements between a first body with internal raceways angularly diverging from each other, and a second body formed with external raceways inclined toward each other, the bearing assembly being adapted for having either body connected to a wheel or to the vehicle body as may be selected, and in which a full complement of tapered rollers can be incorporated between the internal and external raceways, and a single rib ring fixed in position on one or the other of the inner or outer bodies to fully unitize the assembly.

Abstract: A vehicle spring suspension system comprising a primary spring and a secondary spring attached to the primary spring for aiding the primary spring to restore vehicle height and to carry increasing loads placed on or in the vehicle. The secondary spring is connected at one end by an assembly which can have serveral different arrangments for varying the load supporting function of the secondary spring on the primary spring, depending on the need for more or less load carrying cooperation between the primary and secondary springs.

Abstract: A stackable and nestable rack construction formed essentially of wire stock so as to be capable of use in displaying articles on one or a stack of racks, or capable of being nested in groups of two or more to avoid using an unnecessary amount of space. Each rack is composed of similar end leg members that promote the reduction in number of parts or components, and the range of parts adopted to care for a wide variety of articles to be displayed or stored. These characteristics are unique to the provision of obtaining a low cost product.

Abstract: A wobble run-out compensation system includes a compensation plate mountable with respect to a vehicle wheel. First and second manually operable adjusting members allow for independently adjusting the orientation of the compensation plate in first and second orthogonal planes, an adjustment in one plane not affecting the orientation of the plate in the other plane. The orientation of the compensation plate in each of the first and second planes is electronically sensed and substantially continuously displayed on an electronic display as that orientation is being adjusted so that the user is able to observe changes on the electronic display in the orientation of the compensation plate as manual adjustments are made.

Abstract: An aluminum transmission or transaxle case contains a steel shaft which is supported in the case on two directly mounted tapered roller bearings, so that the two bearings confine the shaft both radially and axially. To compensate for the differences in expansion and contraction between the aluminum case and the steel shaft as the transmission or transaxle experiences variations in temperature, a race of at least one of the bearings is fitted with a compensating ring having a coefficient of thermal expansion greater than that of the case or shaft. As a consequence, the bearings operate at a generally uniform setting over a wide range of temperature variations.

Abstract: A lighter-than-air aircraft includes a rigid platform having cargo and passenger compartments and gas bags attached to the platform for holding a gas having a density less than air, thus imparting lift to the platform. The bags are arranged in pairs, there being a pair of spaced apart upper bags along the upper surface of the platform and a pair of spaced apart lower bags along the lower surface. While the bags cover portions of the upper and lower surfaces, both surfaces remain exposed along the longitudinal centerline of the platform, and here the platform is provided with vertical ducts and bays. The ducts house motors and propellers which drive air through the ducts and thus impart a vertically directed force to the platform. The bays hold containers which are lowered from and raised into the bays with a crane that moves along tracks extended along the upper surface of the platform.
