Abstract: An acoustic ear mold for intensifying sound pressure for an acoustic signal derived from an electronic hearing aid worn by a patient, characterized by an ear canal component having defined therein a segmented, air-filled resonating cavity including four coaxially aligned, contiguous cavity segments arranged in communicating relation for intensifying sound pressure in the range of 250 hz to 6,000 hz, the diameter of the segments being mutually unique, the lengths of the end-most cavity segments being equal while the axial lengths of the segments interposed between the end-most segments are mutually unique with respect to all other segments of the cavity, a tubular conduit is connected with the cavity for conveying acoustic signals from the hearing aid while an acoustic output chamber extends from the segmented cavity to the terminous of the component for delivering to the tympanic membrane of the wearer, pressure-intensified acoustic signals.

Abstract: A sprinkler has an orifice through an orifice plate. The periphery of the orifice is preferably not circular; it has at least one corner formed by the intersection of adjacent portions of the periphery. The nozzle plate is preferably domed and mounted concave with respect to the source of the fluid. The orifice may be a number of different shapes including various polygons, tear-shaped or generally circular with notches mounted in the periphery. The orifice may be eccentrically mounted through the dome of the plate.

Abstract: An emitter of very small size connects to a water supply tube by a hollow shank which conducts water to an interior chamber in the emitter housing. Between the chamber and an outlet in the housing the water flow is throttled through an elongated channel having both a wide shallow profile and a narrow steep profile. A free floating (within limits) resilient wafer covers the channel. At initial, very low water pressure at start-up, the wafer does not flex into the channel, thereby affording maximum flow to purge the emitter of unwanted dirt particles and the like. At relatively low operating pressure the wafer flexes into the wide shallow portion of the channel, reducing the flow to a predetermined amount, such as one gallon per hour. At relatively high pressure the wafer flexes further, intruding into the narrow steep slot, thereby compensating for the increased pressure and maintaining fluid flow at said predetermined rate.

Abstract: An apparatus having a frame adapted for earth traversing movement in a direction of travel and having a portion laterally positionable with respect to the direction of travel, a work assembly pivotally mounted on the laterally positionable portion of the frame for movement therewith, and an arm interconnecting the work assembly and the frame to pivot the work assembly through a plurality of positions relative to the direction of travel as the portion of the frame is laterally positioned.

Abstract: A tank for a fluid system which is pressurized in an operative mode and depressurized in an inoperative mode, the tank having a pressure vessel enclosing a chamber and a substantially annular port in the vessel communicating with the chamber; a mount for securing the vessel in fluid transferring communication with the fluid system through the port with the port disposed in substantially upwardly facing relation; and a substantially spherical flow control element captured in the chamber of the vessel and dimensioned gravitationally to seat in the annular port to allow passage of fluid through the port when the fluid system is in the operative mode, to vent pressure from the chamber upon depressurization of the fluid system and to seal the port when the fluid system is in the inoperative mode.

Abstract: A toolholder for use in shaping the blade of a screwdriver with a grinder having a grinding wheel and a guiding surface parallel to the axis of the wheel, the toolholder including a pair of blocks adapted to clamp the shank of the screwdriver between them, each block providing a guiding surface angularly related to the shank and disposed oppositely of the other block; clamps spaced along the axis to draw the block onto the shank and selectively adjustable to bring the guided surfaces into normal relation with a plane normal to the axis; and a pair of projections on the blocks bearing indicia indicating the relative spacing of their ends when the guided surfaces are in such normal relation, the toolholder being guided by engagement of one of the guided surfaces with the guiding surface to shape one side of the blade and being invertible with the screwdriver for guidance of the toolholder by engagement of the other of the guided surfaces by the guiding surface to shape the other side of the blade.

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 grapevine generally resembling the Thompson Seedless Grapevine (unpatented), but distinguished by bearing, without girdling or application of a growth regulator, grapes of a size borne by the Thompson Seedless variety only when so treated and distinguished by bearing bunches of grapes which are substantially free from shatter in cold storage and when subsequently displayed for sale.
