Abstract: Embodiments of the present invention provide an improved yoga or exercise mat shape that allows instructors and students to see each other in all yoga poses without re-positioning mats. The mat shape also ensures that the participants maintain all body parts on the mat during all poses. The mat is further provided as a one-piece configuration to allow an easy and hassle-free set up and use experience.

Abstract: Depressed manhole covers affect vehicles negatively. The B-W Manhole Cover-Cover is a recycled rubber disc attached to the existing manhole cover with toggle-bolts. It will provide proper elevation.

Abstract: A spinner for attachment to the hub of a spoked bicycle wheel generally comprises a body assembly and a contact for contacting a spoke for spinning the spinner about the hub. The body assembly comprises a bearing portion comprised of a plurality of individual bearing arc sections adapted for insertion between the spokes of the wheel and joined around the hub and radial display surfaces, either integral with the arc sections or attached to the bearing portion. The display surface may include an attachable radially outer portion of different wheel sizes and configurations.

Abstract: A method of manufacturing a multi-strength honeycomb core and a multi-strength honeycomb stricture produced form the multi-strength honeycomb core. The method includes the steps of (a) stacking first layers of a first thickness with adhesive at a first adhesive spacing to produce a first honeycomb core having a first density and (b) stacking second layers of a second thickness with adhesive at a second adhesive spacing onto the first honeycomb core to produce a second honeycomb core having a second density stacked on top of the first honeycomb core. The method may also include the step of (c) stacking third layers of a third thickness with adhesive at a third adhesive spacing onto one of the first and second honeycomb cores to produce a third honeycomb core having a third density stacked on top of one of the first and second honeycomb cores.

Abstract: A retainer maintains a body of standing washing liquid against the outside surface of a mat, such as a pulp mat. The mat moves on a vacuum screen which draws washing liquid from the body of liquid through the mat to clean it. The retainer pivots to adjust different mat heights and allows clumps of material on the mat to pass underneath the retainer. Clumps on the mat are also smoothed into the mat as the clumps pass underneath the retainer.

Abstract: An improved stock washer for removing impurities from a porous mat disposed over a vacuum head is disclosed. In one application in connection with an industrial paper making process, paper pulp forms a porous mat over a rotating drum which has a vacuum on the inside. The washer includes an elongate housing, defining a chamber therein, disposed above the drum with a slot along its bottom and resilient, downwardly-extending wipers at the slot edges, Water flows into a pipe extending the length of the chamber. The pipe has holes along its sides to direct water into the chamber downwardly and outwardly. The pipe, which extends through the ends of the housing, is mounted to adjustable mounts at both ends to allow the washer height above the mat to be adjusted. Water flows through the holes in the pipe and accumulates at the chamber bottom where it is directed into the mat by the resilient wipers. The water flows through the mat into the drum displacing chemical impurities in the process.

Abstract: Output signal samples from a solid-state imager, responsive to dark currents accumulated therein, are applied to slope responsive circuitry for generating a signal which can be used, for example, for field shading correction or imager temperature control. Dark current slope responsive measuring circuitry is particularly advantageous over prior dark current measuring circuitry since it is uneffected by DC offset of the dark current signal which results from imager mask misregistration or carrier diffusion when receiving radiant energy.

Abstract: A high voltage winding assembly is disclosed which provides a substantially rectangular high voltage pulse output in response to a magnetically coupled pulse input thereby resulting in improved regulation of the output voltage. A plurality of narrow width and relatively high windings, referred to as washer-shaped windings, is mounted over a primary winding. The height and width of each winding is selected to produce a predetermined capacitance of the winding. The washer-shaped windings are a-c electrically separated from each other by means of diodes connected in series between the windings. The use of the diodes and the selection of the proper height to width ratio positions the a-c null of each winding somewhere within the winding. The washer-shaped windings are separated or spaced from each other by means of a dielectric, the spacing controlling the leakage inductance of the high voltage winding without substantially affecting the capacitance.
