Abstract: A machine includes a frame, a conveyor with a plurality of open-top bottom-apertured recesses for receiving, conveying and dropping skin-containing berries. Upper and lower needle assemblies are supported on the frame above and below the conveyor. Each needle assembly includes a plurality of needles with five-star-knife-edged sharp tips and an actuator mechanism for oscillatingly moving the needles as the recesses pass the needles, the needles being movable between an extended position where the sharp tips penetrate opposing sides of the skin of the berries but with a stroke causing the tips to only penetrate partially into an interior of the berries causing star-shaped slit patterns. The actuator mechanism also moves the needles to a retracted position where the sharp tips are fully retracted. A related method is provided for piercing multiple sides of the skin of berries without unacceptably damaging the appearance or shape or internal mass of the berries.

Abstract: Hydrogen powered air vehicles that in some embodiments can fly with very long endurance (10 or more days) at altitudes over 60,000 ft carrying payloads of up to 2,000 pounds. Embodiments may include features such as large wingspan relative to fuselage and an all composite or partial composite structure for light weight and strength. The aircraft of the invention use one or more internal combustion engines adapted for hydrogen combustion, each engine driving propellers. The hydrogen fuel is stored on board in containers, located within the fuselage, as a cryogenic liquid, and is vaporized in a heat exchanger before delivery to the internal combustion engine.

Abstract: A solar powered aerial vehicle includes an elongated airframe incorporating lifting and control surfaces, a mechanism for propelling the airframe through the air such that lift developed by the lifting surface is equal to or greater than the weight of the aerial vehicle, a planar solar sail coupled to the airframe and having at least one surface adapted to collect solar energy during the day and to power the propelling mechanism with a first portion of the energy collected, and an apparatus such as a fuel cell/electrolyzer for storing a second portion of the solar energy collected by the solar sail during the day and for powering the propelling mechanism with the second portion of energy during the night. The vehicle is capable of continuous operation at northern latitudes and during the winter months for extended periods without landing or refueling.

Abstract: Ground carts to support skid equipped aircraft and to maneuver these craft safely on the ground during taxiing for take off, recovery, servicing, and transport to maintenance or storage. The ground carts provide the capability to minimize risks of damage to aircraft during towing by lifting the aircraft off the ground. Further, an embodiment of the ground cart of the invention includes the ability to rotate the aircraft on a cart platform up to 90° from the direction of forward motion of the cart to facilitate movement in and around the airport apron/hanger and to counter cross winds during take off. In addition, carts may be controlled from the aircraft, for example to provide for steering control until the aircraft is launched, cart braking, platform rotation, and other maneuvers.

Abstract: A new and improved appliance boom having opposite ends. One of the ends is adapted to be secured to the bucket of an articulated powered bucket loader. The other end is adapted to be secured to an appliance. The boom has means for guiding appliance control cables from end to end. At least one control cable having opposite ends is trained through the means. One of the control cable ends is attached to the appliance; the other of the control cable ends is attached to a control in the cab of the bucket loader to which the boom is attached. The appliance cradle may be secured to appliances ranging from crane pulleys, chain saws, and rotary drills, reciprocating saws, to other rotary or reciprocating equipment. The appliance boom may be secured to the bucket of a conventional bucket loader and unattached conveniently and stored when not in use.

Abstract: Methods are provided for preventing or reducing N-methyl-D-aspartate (NMDA) receptor agonist-mediated neuronal cell death by administering a glial cell line-derived neurotrophic factor (GDNF) protein product.

Abstract: A method for treating paper which comprises applying to the surface of the paper an aqueous medium containing a sizing composition consisting essentially of 75 to 99.9 wt % polyvinyl alcohol which is at least 95 mole % hydrolyzed and 0.1 to 25 wt % ketene dimer represented by the formula: ##STR1## wherein R and R.sup.1 are the same or different hydrocarbyl groups having 8-30 carbon atoms.

Abstract: An improved papermaking process has been developed to enhance the properties of the resultant paper or paper-type products. The process involves adding a polyvinyl alcohol/vinylamine copolymer along with a crosslinking agent at the dry end step of a conventional papermaking process. Improvements in the properties of the resultant paper products are observed, especially at low levels of copolymer addition.

Abstract: A stability augmentation system for a forward swept wing aircraft is disclosed that corrects a dynamic instability phenomenon which occurs when the whole vehicle (rigid body) motion couples with the wing structural motion. The sensors are positioned and their output signals combined such that wing structural motion is isolated. Specifically positioned wing control surfaces are operated to suppress such motion with minimal resulting rigid body pitch motion inducing inputs.
