Abstract: A method and apparatus for separation of almond kernels where there is a mixture of almond kernels with almond kernels held with or within the shells the method comprising introducing the mixture onto two contra rotating rollers which are rotating upwardly through a separation gap and which have their axis inclined to the horizontal so as to cause feeding of the mixture from an entry location to an exit location, the separation gap being selected so that with the alignment caused by the roller action, almond kernels without shells will pass therethrough while almond kernels with shells will pass along to an exit location. The apparatus provides two contra rotating rollers held the selected distance apart to provide for the separation and being adapted to be contra rotating and includes abutments in the surface to provide an occasional tipping action to almond kernels moving along the surface of the rollers.

Abstract: Novel telechelic olefin and hydroxy polymers particularly those of polyisobutylene are prepared according to the process set forth herein. Preparation of a telechelic diolefin polyisobutylene includes the steps of refluxing a solution of telechelic dihalogen polyisobutylene, adding a solution of a strong base such as potassium t-butoxide and stirring to form the telechelic diolefin polyisobutylene. This telechelic diolefin can be converted to the telechelic dihydroxy by refluxing a solution of the former, hydroborating the diolefin to a polymeric borane and oxidizing the polymeric borane to form the telechelic dihydroxy polyisobutylene. The processes are also applicable to the conversion of trihalogenated polyisobutylenes to telechelic triolefin and trihydroxy polyisobutylene tristars.

Opposite ends of the base are each characterized by an opening of decreasing width from the bottom of the base upwardly, thus being adapted for receipt by various size tires with the crown of the tire being received through the open bottom of the base. Mounted atop the base is a tray which may be pivotally secured thereto.

Abstract: A rubber liner having resistance to fluid diffusion is disclosed. The rubber liner is compounded from natural or synthetic rubber in combination with a thiuram compound such that the blend upon curing has a durometer hardness no greater than about 75 on the Shore D. Scale. The rubber liner may be combined with a heat-resistant rubber layer to form a rubber laminate resistant to heat and fluid diffusion. The heat-resistant rubber layer may be composed of natural or synthetic rubber in combination with a salt of a benzimidazole which resists oxidation at elevated temperature over extended time periods with a retention or increase tensile strength. The rubber laminate may also have a metal-adhesive rubber layer to secure the laminate to metal substrates of industrial production tanks, vessels, pipes, and other containers where industrial processing continually exceeds 180.degree. F.

Abstract: An oscillating rheometer die set is disclosed, having modifications to the lower die apparatus, the upper die apparatus, and the oscillator head.

Abstract: A pair of metallic strips are provided for the improvement in the stalling aerodynamics of the Cessna Series 150 and 152 aircraft, especially during conditions which would otherwise generate an unintentional spin entry, followed by a fatal accident. The strips are secured to the leading edge of the airplane wing at a point substantially adjacent to each wing root. Each strip has a plurality of raised surfaces for modifying the airflow over the upper wing surface, and a concave surface which is placed against the leading edge of the airplane wing. Fasteners placed in recessed areas on the strip secure the strip to the wing's leading edge. The addition of these strips to the airplane wing modify the stall pattern in its area of separated airflow over the upper surface of the wing in such a way that the pilot is provided with greater aileron control during stalling conditions.

Abstract: A beverage dispenser pumping system having a mass reservoir for receiving a plurality of beverage-containing bottles in such manner that all of the bottles feed a common line but no intercommunication of beverages among the bottles is possible. The mass reservoir feeds a pressurized pump which is operative for driving an expandable and contractable dispensing line. A dispensing valve is located near the end of the dispensing line for initiating and terminating the flow of beverage from the pump, through the line and out of a dispensing head. A one-way valve interposed within the dispensing line and closely adjacent the pump retains liquid pressure within the line and inhibits any bleeding of beverage from the line back into the pump when dispensing has terminated. A hydraulic accumulator is presented between the dispensing valve and the dispensing head to withdraw beverage from the end of the dispensing line when the dispensing valve shuts off so as to prohibit extraneous drippage from the line.
