Abstract: A grape vine which bears fruit resembling that of the Thompson Seedless grape vine (unpatented), which it most nearly resembles, but distinguished by bearing berries of large size in shatter-resistant bunches without girdling the vines or the application of gibberellin, by superior storing and shipping characteristics, and by maturing about 30 days later than fruit of the Thompson Seedless variety.

Abstract: A grape vine generally similar to the Black Rose grape vine (unpatented), but distinguished therefrom by being of more vigorous growth and by bearing grapes which mature about 30 days later, which have superior shipping characteristics, and which ripen more evenly so that each grape of the new variety is more uniformly and darkly colored than grapes of the Black Rose variety.

Abstract: A roof is prepared wherein the water barrier layer is placed on a roof deck and waterproof thermal insulation is placed over the water barrier layer. The water barrier layer is not subjected to the extremes of temperature that are encountered when the water barrier layer is the outermost element of the roof structure.

Abstract: A dampened bolster and side frame assembly for a railway truck including widened lands on the side frame and a plurality of spaced wedges on each side of the bolster and on opposite sides of the frame center line.

Abstract: In a process wherein ethylene or propylene is carbonylated with carbon monoxide to form carboxylic acid esters in the presence of a catalyst complex of one mole of BF.sub.3 and one mole of alcohol, the invention concerns a technique wherein the catalyst is recovered from the reaction product and recycled. The carbonylation is carried out until approximately one-half of the alcohol is consumed, to form a reaction mass containing the BF.sub.3, the alcohol, and the carboxylic acid ester in a 2:1:1 molar ratio. In the first step, the one mole of the free BF.sub.3 is vaporized from the reaction mass. The remaining admixture is a 1:1:1 mixture of the three aforesaid compounds. To this mixture additional alcohol is added and the mixture is subjected to distillation. A carboxylic acid ester/alcohol azeotrope and residual alcohol are removed by the distillation, to leave a residue containing a 1:2 BF.sub.3 /alcohol complex. This complex is combined with an additional mole of BF.sub.

Abstract: A swim suit designed for competitive racing is made of knit mesh fabric of hydrophobic synthetic stretch yarn knitted in a small atlas type of pattern having a multitude of openings therein. The yarn is within the range of 40% to 100% denier so that the openings comprises in the range of 40% to 60% of the fabric, whereupon the entire suit has flow-through characteristics, that is, water and air pass freely through the openings in the mesh, thereby avoiding entrapment of water and/or air, with resultant avoidance of billowing and bubbling while being sufficiently opaque to conceal the underlying body of the wearer. Both men's and women's suits are provided and each includes a liner portion formed of the same fabric as the swim suit.

Abstract: A shoulder garment adapted to be worn particularly by persons who are exposed almost overnight to strong sun rays to thus prevent a sun burn on the shoulders of the wearer. Also, the shoulder garment may be worn over a jacket or shirt so as to present an ornamental article of wearing apparel.

Abstract: An article of wearing apparel has a panel of readily-expansible material in the front upper half thereof to enable that article of wearing apparel to be worn by persons of different sizes and configurations; and it has a panel of less-expansible material overlying and concealing the panel of readily-expansible material. The panel of less-expansible material permits free expansion and contraction of the panel of readily-expansible material while effectively concealing the latter panel.

Abstract: A protective helmet for providing protection against impact to a wearer's head. The helmet includes a helmet shell and an apparatus or component which provides for sizing and energy absorbing capabilities. This component is made of a mesh tube with loose beads of an energy absorbing material stuffed into it. The stuffed tube is flexible, preferably being coiled onto a comfort line and secured to it. The comfort liner and stuffed tube are then attached to the helmet shell. The loose beads are adjustably moveable in response to a slight amount of steady pressure as applied during donning of the helmet, to adjust so as to provide a comfortable fit to the wearer. Preferably the mesh tube is of a knitted fabric, while the beads are preferably of polystyrene. Typically, the comfort liner is of perforated leather, to be breathable.

Abstract: A stent for a cardiac valve comprises a metal base ring having metal legs projecting therefrom in a generally axial direction, each leg being flexible in such a manner that, when the stent has a valve installed therein and the valve is under pressure such as when operating in the heart, each respective leg can resiliently deform over substantially its whole axial length to take up strain in the valve without impairing its performance.

Abstract: This invention relates to the electrochemical machining of integrally formed prosthetic heart valve structures in which both the structural integrity of the valve and the blood flow through the valve is improved as a result of the integral formation of the valve structure. In particular, such heart valves comprise a ring and a pendant structure, such as a strut, for supporting the opening and closing of a discoid valve occluder. Integral formation of the strut with the ring permits the cross-sectional shape of the strut to be machined without overheating and distortion to conform to a teardrop shape having favorable fluid-dynamic characteristics thereby improving the flow of blood through the valve across the strut. The integral formation of the strut with the ring further results in the elimination of the weld fillet between the strut and the ring, thereby permitting the height of the ring to be reduced, which further improves the fluid dynamic characteristics of the valve.

Abstract: A new intraocular lens, suitable for use in artificial lens implantations and having a light-focusing lens body and two position fixation means therefor, is disclosed. One position fixation means extends generally radially from a first region of the periphery of the lens body and the other position fixation means comprising a pair of support members extends generally radially from a second region of the periphery of the lens body spaced from the first region. At least one of the support members of said latter position fixation means is resiliently deformable between a normal undeformed condition, in which the entire lens will not pass through an incision in the eye of a given length and a deformed condition, in which the entire lens will pass through such given incision. During insertion of the lens into the eye, sufficient force is applied to the deformable position fixation means to maintain it in the deformed condition thereof.

Abstract: A decomposition latrine has a chamber (20) in which decomposable material (27) is heated with the help of a heat source (28) to a temperature in the range of 45.degree.-80.degree. C., the attainment of a rapid thermophilic decomposition process with simultaneous pasteurization of the material thus being enabled before the material is removed from the chamber. The pasteurized portion of the mass is movable away from the region at the heat source with the help of a stirrer (26), rotatable by means of an electric motor.

Abstract: A toilet support for use with a toilet bowl, comprising a pair of first arm portions, mounted on the toilet bowl for pivotal movement. A pair of second arm portions are mounted on said first arm portions and moveable generally axially of the first arm portions. The ends of the second arm portions are joined to one another by a connecting portion such that said first and second arm portions can be moved about the pivot and axially relative to one another such that in a first position the connecting portion of the second arm portions engages the edge of the toilet bowl and in another position the first and second arm portions are extended axially relative to one another such that the connecting portion can engage the floor adjacent the bowl and forwardly thereof. The first and second arm portions can be locked in any set axial position relative to one another.
