Abstract: A member suitable for use at the exterior surface of an aircraft for structural or containment purposes includes a nonmetallic base or core and a thin electrical shield over that surface of the base that is presented outwardly. Preferably the base is a composite consisting of graphite fibers and a cured resin in which the fibers are embedded. The shield is tin or a tin alloy that is bonded to the surface of the base, preferably by metal spraying techniques. An electrical discharge, such as lightning, that attaches to the member is dissipated through the shield without impairing the strength or containment capabilities of the base.

Abstract: A storage bin for bulk ice has upper and lower sections that completely enclose a space in which ice cubes are stored. These ice cubes are produced by an ice making machine and are delivered to the ice bin by a conveyor which is inclined upwardly away from the ice making machine. One of the walls on the upper section of the ice bin is inclined to accommodate the inclination of the conveyor and this wall has an opening through which the ice cubes are discharged into the enclosed space. The lower section of the bin has an opening through which the ice cubes are withdrawn for bagging, while the upper section has another opening that provides access to the interior of the bin for breaking up ice jams. Both of these openings are normally closed by doors. Refrigeration equipment extracts heat from the enclosed space of the bin, and the water line that leads to the ice making machine passes through the space so that the water is precooled, thus rendering the ice making machine considerably more efficient.

Abstract: An apparatus for drying seeds and other granular products includes a drying vessel that is connected to a vacuum pump which evacuates air from its interiors. The drying vessel has an enclosing side wall and a tubular portion which is surrounded by the side wall, all such that an annular drying cavity is formed within the vessel. The tubular portion is made from a material that is transparent to microwave energy and houses waveguide-radiators, each of which is connected to a different microwave launcher that is located at the lower end of the transparent tubular portion. The launchers produce microwave energy that is directed into their respective waveguide-radiators which in turn allow the energy to escape through apertures in their side walls. This energy passes through the transparent tubular portion of the drying vessel and into the drying cavity of the vessel. Within the annular drying cavity, the vessel contains drying columns into which the granular product is directed.

Abstract: A grinding machine for automatically cutting gashes into the end of a fluted end mill blank includes a base on which a grinding wheel is supported such that it moves back and forth tracing a swing path. The end mill blank is held in a work head that is supported upon a vertical slide which is in turn mounted upon a horizontal slide that moves over the base. The work head pivots about two axes for positioning the end mill blank at the proper angle with respect to the grinding wheel. A feed assembly advances the horizontal slide incrementally, and at the same time moves a control slide that actuates various switches which control the operation of the machine. The feed assembly also shifts the vertical slide at the proper time within the grind cycle. In addition the machine has a wheel dresser which automatically dresses the grinding wheel when the feed assembly shifts from a rough feed to a fine feed.

Abstract: The method for diagnosing vehicle wheel alignment characteristics in which the longitudinally spaced steerable and non-steerable wheels are equipped with means for permitting the practice of displaying the alignment characteristics of the planes of rotation of the steerable wheels in relation to the geometric center line and the thrust line effect of the non-steerable wheels on the steerable wheels, in combination with the steps of adjusting the plane of rotation of the non-steerable wheels for bringing the thrust line effect thereof into substantial tracking relation with the geometric center line of the vehicle, and monitoring the effect of the adjustment imparted to the non-steerable wheels.

Abstract: A bearing for a mill roll is forced to and held in the proper position on the neck of the roll by a clamp-up device that fits around the roll neck between the bearing and a conventional splint hinged ring which serves as a backing for the device. The clamp-up device includes inner and outer rings which together form an annular fluid chamber, and when this chamber is pressurized, the outer ring extends, forcing the bearing to its proper position on the roll neck. Within the chamber, each ring is provided with ramps which align and come against each other when the outer ring is turned to the proper angular relationship with respect to the inner ring, and when the outer ring is so disposed it will remain axially extended to hold the bearing in its proper position on the roll neck during operation of the mill roll. A locking plate is provided to lock the rings against rotation relative to each other once they are in the proper angular relation.

Abstract: A medium for determining Escherichia coli sensitivity to a pre-selected antimicrobial agent. The medium contains nutrient sources, inhibitors to inhibit growth of gram-positive and of other gram-negative micro-organisms, and an indicator which will show metabolic activity or lack thereof by E. coli in the medium, and a specific antimicrobial agent whose effectiveness against E. coli is being tested. If a given agent is effective against E. coli when E. coli is added to the medium containing that agent, the medium will remain clear. If the specific agent is ineffective against E. coli the color of the medium containing E. coli and that agent will change to blue as the E. coli metabolizes in the medium and produces acid.

Abstract: A process for removing hulls from soybeans comprises the steps of placing the soybeans in an atmosphere of reduced pressure, subjecting the beans to microwave energy while the beans are within the atmosphere of reduced pressure, removing a portion of the moisture from the beans until the moisture content of the soybeans is about 7.46 to about 10% on a wet basis, removing the soybeans from the atmosphere of reduced pressure, the temperature of the soybeans leaving the reduced pressure atmosphere being at least 110.degree. F. and less than 160.degree. F., immediately cracking the hulls of the hot soybeans without tempering, and removing the hulls from the hot soybeans.

Abstract: A reducing mill for handling a wide variety of trash and waste material needing reduction to a state for easy subsequent handling and for separating certain components of the material by a specific gravity characteristic. The reducing mill embodies means for mixing and segregating components of the trash and waste material by the combined jet and negative pressure gradient induced by the action of an air stream, and by the cooperation of a hammer mill housed in a casing formed to effect recycling of material which needs or may require recirculation for further reduction and segregation.

Abstract: An electrical switch includes a body having one open end exposed for adaptation of a pyrotechnic cartridge and the other end sealed by the base of a pin type connector assembly having short conductive pins and elongated conductive pins with relief areas containing insulative material. The pins are inserted into the body cavity. A conductive grounding plate or plates have tabs which bite into the pins and connect selected pins in a first operational state. A plunger having fracturable bosses is located adjacent the contact plate. Upon activation of a pyrotechnic cartridge, pressure is applied to the plunger, causing fracture of the bosses and resulting in the displacement of the plunger to move the contact plate to a different position thereby changing the number of closed circuits.

Abstract: Apparatus operable to process waste material from the usual relevant sources by breaking down such material into components so that as much of the substantially uncontaminated aluminum may be segregated for purposes of recycling, and a method for recovery of the aluminum in waste material in which the method includes a step of extracting the aluminum from the waste material by the application of magnetism.

Abstract: A method of effecting compensation of cooperatively coupled vehicle wheel aligner instruments since a shift or change of position of either one of a coupled pair of angle measuring transducer instruments can introduce changes in the signal values generated in both transducers which are representative of errors not heretofore recognized in prior alignment instruments. The method is directed to initially generating signals responsive to the position of rotation of vehicle wheels at each of two positions 180.degree. apart, simultaneously recording the generated responsive signals from each transducer instrument at each position of rotation of the vehicle wheels, and applying the recorded responsive signals at the two selected positions of wheel rotation upon the initial signals at the selected positions of wheel rotation such that the transducer instrument signals are mutually compensated for aberrations in the relationship of the mounting of the transducer instruments on the vehicle wheels upon being rotated.

Abstract: Two indirectly mounted tapered roller bearings that are located between a spindle and a hub are set by first bringing one of the bearings into a condition of no end play and then measuring the distance between the cup of the second bearing and the end of the spindle. A spacer is then selected and fitted between the end of the spindle and an end plate that is bolted against the spindle. The end plate abuts against the back face of the cone for the second bearing, and the end plate position, which is controlled by the thickness of the spacer, determines the setting for the bearings. The proper thickness for the spacer is determined by subtracting the measured dimension from a value derived from a table.

Abstract: Energy conservation apparatus for internal combustion engines in which a restriction device is used with a fluid supply associated with a heat exchanger which converts the fluid into a vapor prior to being drawn into the fuel-air mixing carburetor or injector, the apparatus utilizing the negative pressure from the engine for moving the fluid through the system at a rate related to the engine displacement. In the apparatus, the restriction device effects control over the fluid quantity being moved into the engine in a vapor state, and operates through the presence of a fine-bore tube of a fixed diameter in the passage between the fluid supply and the engine.

Abstract: A multirow bearing for supporting a work or back-up roll of a rolling mill includes inner and outer races and tapered rollers arranged in two end rows and two intermediate rows between corresponding raceways on the inner and outer races. The inner race is a unitary structure, while the outer race is comprised of two double cups. The tapered rollers of the intermediate rows have their large ends presented toward each other and those ends bear against a center thrust rib that may be free to float in the axial direction so as to equalize radial loads between the rollers of the two intermediate rows. The radial clearance between these rollers and their respective raceways can be less than the clearance between the rollers of the end rows and their respective raceways so that the rollers of the intermediate rows carry most of the radial loading.

Abstract: A ventilation system for a livestock house includes a heat exchanger through which both warm moist air from the interior living area of the house and fresh make-up air from the outside are passed, so that heat will transfer from the former to the latter. Prior to entering the heat exchanger, the warm moist air passes through a filter device that removes particulates from it, so that the particulates do not combine with condensation in the heat exchanger to block the heat exchanger. The fresh air, after being warmed in the heat exchanger passes into an elongated distribution plenum located slightly below the ceiling of the house, and this plenum contains apertures which direct the fresh air horizontally into the living area. Moreover, the upper surface of the plenum is located directly below an elongated opening in the ceiling.
