Abstract: Methods, devices, apparatuses and systems are disclosed for performing mammography, such as utilizing tomosynthesis in combination with breast biopsy.

Abstract: Disclosed are devices, systems and related methods of employing one or more horticultural planters that are easy to use and maintain, and which provide illumination and/or entertainment services (i.e., music and/or other audio) utilizing one or more individual planter units.

Abstract: A game play device provides simplified movements and piece interaction in a capture-style board game. The device includes a game board defining a playing surface. Straight lines defining a plurality of isosceles triangles defining a playing field. Each of a plurality of playing pieces is shaped to correspond to and be alignable with to cover at least one isosceles triangle when placed on the playing field. The playing pieces including at least one each of four distinctly shaped playing pieces.

Abstract: A tongue cleaning device includes a sponge-like tip that is fluidically connected to a refillable reservoir that will contain mouthwash or the like. A scraper is located adjacent to the tip and a check valve in the reservoir prevents fluid from flowing away from the tip in the event the orientation of the device is suddenly changed.

Abstract: The third stage nozzle has an airfoil profile substantially in accordance with Cartesian coordinate values of X, Y and Z set forth in Table I wherein X and Y values are in inches and define airfoil profile sections at each distance Z and Z are non-dimensional values within a range from 0.1 to 0.9 convertible to Z distances in inches by multiplying the Z values of Table I within the range by a height of the airfoil in inches. The profile sections at the Z distances are joined smoothly with one another to form the nozzle airfoil shape. The X and Y distances may be scalable to provide a scaled-up or scaled-down airfoil for the nozzle. The nominal airfoil given by the X, Y and Z distances lies within an envelope of ±0.160 inches.

Abstract: Third stage turbine buckets have airfoil profiles substantially in accordance with Cartesian coordinate values of X, Y and Z set forth Table I wherein X and Y values are in inches and the Z values are non-dimensional values from 0.03 span to 0.95 span convertible to Z distances in inches by multiplying the Z values by the height of the airfoil in inches. The X and Y values are distances which, when connected by smooth continuing arcs, define airfoil profile sections at each distance Z. The profile sections at each distance Z are joined smoothly to one another to form the bucket airfoil shape. The X, Y and Z distances may be scalable as a function of the same constant or number to provide a scaled up or scaled down airfoil section for the bucket. The nominal airfoil given by the X, Y and Z distances lies within an envelop of ±0.150 inches in directions normal to the surface of the airfoil.

Abstract: A valve for controlling the flow of a gas in a gas burning torch comprises a housing having a flow passageway therethrough, a valve seat in the passageway, and a valve stem carrying a ball valve element for engaging and disengaging the valve seat to respectively close and open said passageway. A rotatable operating knob for displacing the valve stem is isolated therefrom by a ball thrust bearing, and the valve stem is supported in the housing for rocking movement transverse to the stem axis.

Abstract: The peripheral pump includes a wall bounding a pump chamber and provided with a substantially annular delivery port with a base having a circular segment with a center; a circular cylindrical impeller revolving in the pump chamber, having two end faces and a rim of blades disposed at intervals along a circumference of the impeller so that a groove-like gap is formed between two adjacent blades, the groove-like gap having a base, as seen in a longitudinal section through the pump, having a circular segment with a center substantially coincident with the center of the circular segment of the delivery port, the center of the circular segments being located within an outer contour of the impeller.

Abstract: The apparatus for feeding an electrolyte fluid medium includes a housing and, mounted in the housing, an electric drive motor and a pump driven by it. The electric drive motor has a commutator device connectable electrically to a conductor supplying current to it. The commutator device includes a commutator attached to the armature spindle of the drive motor, at least two contacting brushes engaged with contacting surfaces of the commutator and prestressed spring devices for holding the brushes against the commutator. To meet the operating requirements and combat the erosion, the prestressed spring devices are leaf springs (42,44). One end (46) of each leaf spring is held fast against the housing and the other end (72) supports one of the contacting brushes (38,40). Each contacting brush (38,40) has a protruding portion (50) engaging in a throughgoing opening (52) of a leaf spring (42,44).

Abstract: For reasons of technologically simple, economical manufacture, a coupler element for coupling an injection nozzle (11) to a connector neck (12), coaxial with it, on an injection line is embodied as a one-piece plastic clip (10), which comprises a C-shaped annular disk (16) and spring legs (17) protruding away from the annular disk (16) in the axial direction of the clip and having inwardly oriented detent protrusions (18). With a groove engagement region, the annular disk (16) engages a circumferential groove (15) in the injection nozzle (11), while after the coaxial insertion of the end of the injection nozzle (11) into the connector neck (12), the detent protrusions (18) snap into place behind a locking collar (14) on the connector neck (12) (FIG. 1).
