Abstract: ABSTRACT:         A container for the storage, shipping and dispensing of  pellets filled with gases such as hy-drogen, deuterium, tritium, or mixtures of the same which has compactness, which is safe against fracture or accident, and which is reusable.  The container consists of an outer housing with suitable inlet and outlet  openings and electrical feed elements, the housing containing an activated sorber material in the form, for  example,  of titanium sponge or an activated zirconium aluminate cartridge.  The gas to be stored is introduced into the chamber in the form of small spheres of material such as glass, plastic or plastic-carbon, or other materials which typically contain hydrogen isotopes.  A specified quantity of filled pellets are introduced into the chamber after which it is  evacuated  and the sorber baked out by heating.  Thus, any breakage in transit of the pellets will  permit the gas to be sorbed and prevent release until the cartridge is again reheated.     i.

Abstract: Abstract of the Disclosure A unitary, prefabricated railway car roof and its method of manufacture.  Two elongated flat webs of galvanized sheet metal disposed in edge to edge abutting relation, and having a combined width slightly greater than the width of the finished roof, are preferably unwound from rolls and are intermittently moved through a welding station which bonds the two webs together into a single wide sheet.  Downstream of the welding station the sheet is fed through dies of a hydraulic stamping press which form transverse corrugations at approximately two foot intervals in the combined sheet to provide stiffening panels extending substantially the full width of the roof, and at the same time to form a gable with the longi-tudinal weld line being the crest of the gable and defining the longitudinal centerline of the roof.  In the finished roof, the stiffening panels cooperate with conventional end and side walls of a railway car to support the roof structure, and the peripheral edge portions of the roof are either welded or riveted to the upper end and side plates of the car.     -1a-

Abstract: TREE SHEARER                  Abstract of the Disclosure A shearing device is disclosed for severing trees and the like.  The device is vehicle mounted, preferably on the front of a tractor, so that forward movement of the tractor causes shear-ing of a tree in contact with the device.  The device includes a frame member with a pair of forwardly extending spaced arms one of which has a pivot member mounted thereon, with the pivot mem-ber carrying a severing or shear element that can be moved in an arc toward and away from the other arm of the frame member.  A tree brought into contact with the severing element will be severed as the severing element is caused to move toward the other arm of the frame member due to continued forward movement of the vehicle.  After a tree has been severed, the pivot member is preferably biased to automatically return to normal position near the end of the arms of the frame member with the severing element at least partially spanning the space between the arms.

Abstract: A CLOTHES WASHING MACHINE AND   METHOD OF WASHING CLOTHES ABSTRACT OF THE DISCLOSURE An improved clothes washing machine and method of washing clothes for increasing the unbalance capacity of the machine.  The machine includes a tub for containing water, a clothes receiving basket in the tub, the basket having perforations arranged in a pattern from the top to the bottom of the side wall of the basket, a pump for removing water from the tub, and a mechanism for rotatively accelerating the basket from zero to over 220 revolutions per minute.  The unbalance capacity improvement is achieved by retaining between 20 and 40% of the initial water in the machine as measured under water only load conditions until 220 revolutions per minute is reached, pumping water continuously from between the tub and basket during such basket acceleration and discharging it from the machine, and restricting the flow of water from the basket to the tub such that the level of water between the tub and basket is lower than the level of water in the basket during such acceleration.

Abstract: HIGH DENSITY VIDEO RECORDING DISK                        ABSTRACT A video recording disk that is optically readable has data represented in a form that permits data track revolu-tions to be spaced close together without an intervening guardband or with only a narrow guardband.  The track revolutions are in two sets that form a parallel spiral or alternating concentric circles so that a track revolution of one set is separated from other track revolutions of the same set by intervening track revolutions of the other set.  Binary data is represented on the tracks by deformations or the absence of deformations, and the record is read as destructive inter-ference in a light beam produced at the location of a deformation. Deformations of the first set of tracks have a depth that is appropriate to be read with a wavelength designated lambda 1, and deformations of the second set have a depth to be read by light of a wavelength lambda 2.  Light that is reflected from an adjacent track does not have any significant data content, and the track revolutions can be located close together without producing significant interference in the signals.
