Abstract: A new and distinct cultivar of black walnut tree (Juglans nigra L.) which is distinctly characterized by extremely rapid growth rate, fair central stem tendency, earlier than average time of leafing, and average straightness thereby producing good timber qualities. The new variety has outstanding nut qualities as well, such as abundant annual crops of large-sized nuts, begins nut-bearing early in life of tree, average 2 nuts per cluster, and produces kernels which exceed about seventeen (17) percent of nut weight. The nuts are large and ripen early. The pistillate flowers mature early while pollen maturity is mid-season. In most years there is no overlap in female and male flowering. Flowering begins very early in the life of the tree. This new variety of black walnut tree was discovered by the applicant near Fritchton in Knox County, Ind., in a cultivated area.

Abstract: A new variety of a spider form chrysanthemum distinguished by its improved darker pink coloration when compared with its parent variety "Westland" (P.P. 4,589), particularly with respect to color retention, which is better than "Westland" which fades to a lighter pink more quickly. In all other respects, this sport of "Westland" is the same as its parent.

Abstract: A hydrostatic pump unit is located within a housing which serves also as a hydraulic fluid sump. A displacement control valve for controlling actuators for adjusting the angular position of a swashplate of the pump unit is mounted on the exterior of the housing. Disposed along the axis about which the swashplate is adjustable and joining the swashplate to a shiftable sleeve of the control valve is a feedback shaft which acts to return the valve to a null condition when the swashplate arrives at a commanded new displacement effecting position. The feedback shaft has a passage extending therethrough which acts as a drain connection between the valve and the sump defined by the housing. A check valve is located in the passage for preventing fluid from draining from the housing when the valve is disconnected from the feedback shaft for service.

Abstract: Apparatus for measuring progressively the absorbance changes of a large number of aliquots from a plurality of different samples. The sample introduction, testing instructions, aliquot preparation, reagent dispensing, absorbance measuring and data recording all can be accomplished in a continuous mode of processing. Stat and batch operation also can be accomplished. The aliquots are in an array of cuvettes which is advanced slowly along a circular path. Photometer means, preferably having several photometric detectors, are mounted in fixed orientation on a common support that advances rapidly along a similar circular path, such that radiation passing through each of the cuvettes is monitored many times by a specific photometric detector by the time that that cuvette completes one circuit of its path. The photometric detectors can operate at several different wavelengths. Many different chemical reactions can be monitored at the same time.

Abstract: The described tube testing apparatus indicates whether a defect is either external or internal, enabling a quantitative classification of defects and an analog representation on location of the defect in the tube wall. The ratio of the signal levels of a defect is taken as a threshold in two different circuit channels. For tubes of a given wall thickness, the ratio of the defect signal levels resulting in the two channels is a fixed number which is a function of the location of a defect in the tube wall causing a defect signal. Uninfluenced test signal voltages from the first channel are available for further evaluation and are applied to voltage discriminators having various threshold voltages.

Abstract: A plastic band is secured around the outside of a prosthetic heart valve adjacent the sewing cushion to protect the valve leaflet material against inadvertent needle punctures and tears while sutures are being placed through the sewing cushion. The band is held in place by a single retention suture which passes through the band and sewing cushion of the valve and extends across the valve orifice. The protector is especially desirable for use with pericardial tissue valves having the tissue mounted on the outside of the valve stent where the tissue is particularly exposed and susceptible to needle damage.

Abstract: A prosthetic heart valve constructed of hemo-compatible materials that is anatomically and functionally similar to the natural aortic valve is disclosed which reduces or eliminates the occurrence of many of the complications found in the use of prior art prosthetic valves. The heart valve is a trileaflet type which has its formed leaflets heat set in a partially open position to reduce pressure required to open the leaflets in response to blood flowing therethrough.

Abstract: An artificial foot for attachment to a prosthetic device securable to a leg stump. The artificial foot is adjustable in length and in height of the instep so as to permit the foot to be snugly inserted in a conventional shoe. The artificial foot includes a simulated toe portion which is horizontally pivotally connected to a sole plate. A spring-pressed linkage normally maintains the simulated toe portion in an aligned position with the sole plate, but permits upward pivotal movement of the toe portion in response to the forces encountered in taking a step. A latching lever frictionally engages the spring-pressed linkage to latch the pivoted toe portion in its upward position during that portion of the step wherein the weight is carried by the other foot. The artificial foot is connected to the bottom plate of a prosthetic device by a plurality of cushion plugs.

Abstract: A toilet flush system designed for manual control of the amount of water used for a toilet flush cycle uses a tank ball, flapper valve, or other type valves to control the closing of a reservoir outlet at selected times prior to or upon completion of the normal flush cycle. The tank ball or flapper valve is modified to overcome its buoyancy such that it rapidly closes the tank reservoir to thereby terminate the flush cycle when the handle of the toilet is released. By maintaining the handle in the operated position, the individual flush cycle can be controlled dependent on the waste to be disposed of, thus permitting a significant saving in fresh water. The buoyancy of the valve is overcome by utilizing a water absorbing material such as sponge material within the valve which, when primed, increases the weight of the valve.

Abstract: There is an emptying opening (18) at a given height on one side of the bottom (29) of the composting chamber (20) in a decomposition latrine with a rotatable stirring means (26a). In normal stirring, the means rotates for moving material away from the opening, and in emptying, the direction of rotation is reversed so that material may be discharged through the opening. The stirring means comprises six to twelve stirring members in the form of flat, bar-like members (50) extending between the end walls (11, 34) of the chamber (20).

Abstract: A liquid reservoir, for example a swimming bath, a test tank or an aquaculture tank, comprises an open-topped container having at least one side wall, a first floor fixed relative to the side wall(s) and a second floor above the first floor which is able to move upwardly and downwardly relative to the side wall(s) in order to vary the height and/or inclination of the second floor in relation to the first floor. The reservoir comprises means for varying the specific gravity of the second floor between a value above and a value below the specific gravity of the liquid of the reservoir. Passageways between the side edge of the second floor and the side wall(s) of the container and/or through the second floor enable liquid to flow between the space between the two floors and another space above the second floor when the height of the second floor is varied.
