Disclosed herein is a moldable foot wedge which when suitably treated as by heat, becomes deformable so that the person for whom the wedge is to be customed fit is allowed to stand on the wedge thereby deforming same to conform identically to the contour of the person's foot, thereby filling voids. An area below the rear heel on one side thereof is defined as a plug which is not subjected to the heat treatment so that a beneficial cant of inclination can be provided to the wedge by not allowing ...

In this assembly of conveyor elements each element is corrugated to comprise a regular series of alternating hollow portions and projecting portions to constitute bucket-like elements having each at one end a bellows structure and at the other end a plain end wall preferably higher in the center of the hollow portions than near the projecting portion; a transverse lip may be formed integrally on one side of the projecting portion, and the bottom of each element is secured to a link of a longitud...

A wire construction is provided in which five fine filaments of stainless steel wire are helically overwound about a center filament, also formed of stainless steel. The diameter of the central filament is slightly larger than the diameter of the helically wound filaments, which are of uniform diameter. The wire so constructed retains a high degree of elasticity following manufacture, and is especially suitable for application as an orthodontic wire for use in bracework for straightening teeth, ...

A floating annular sealing ring having a plastic coated surface is adapted to be received by an annular groove defined by a bushing and shaft sleeve mounted upon a rotating shaft to provide an effective liquid and gas seal. The encapsulated deformable annular seal may include a circular, an oval, a lobed, a rectangular, a square or triangular cross-section, which cross-section is capable of conforming to the inside surface of the bushing sleeve and the outside surface of the shaft when the sleev...

A liquid mirror for high energy lasers. A working liquid such as mercury, used as the reflecting surface for laser light. Dielectric enhanced reflecting techniques can be used to increase significantly the amount of reflection from the working liquid. The liquid is contained in a pressure cell behind a transparent optical flat. By varying the pressure cell of the liquid, compensation for the aberration caused by heat absorption can be made. These same pressure changes can be used to correct for ...

A three actuator deformable mirror having a central axis and six attachment points arranged in pairs on diameters of a circle drawn from the axis is supported on a center post on the axis and has a floating block aligned with the axis surrounds the center post with first, second and third actuators disposed along the diameters, each split into two parts and having a first portion extending between the floating block and one of the attachment points on a diameter and the other part extending from...

A mounting apparatus for a deformable mirror that has a peripheral mounting portion with oppositely facing and parallel mounting surfaces. A base member and a mounting ring have juxtaposed peripheral flange portions with rubber o-rings for engaging the parallel mounting surfaces of the mirror. A plurality of set screws are provided in the base member and the mounting ring in the peripheral flange portions and engage the o-rings for applying and adjusting a mounting force to the mounting surfaces...

A telescope mirror assembly includes a space frame; a deformable mirror body; a plurality of spaced supporting elements bonded to the mirror body by an adhesive; a fastening assembly for releasably securing each supporting element to the space frame for combining the mirror body and the space frame into a self-supporting construction; piezoelements interposed between each supporting element and the space frame for selectively imparting by the piezoelements a pressing or pulling force to a portio...

A deformable base having top and peripheral walls and resiliently deformable interior ribs is formed with a recess in the interior central crown region, the recess being defined by a central web to which a mounting plate is removably attached. The plate is elevated above the ground-engaging parts of the base as a result of which the central web and plate can be downwardly depressed when vertical impact forces caused by a runner contacting the crown region are encountered. This downward depressio...

The radially deformable pipe of the invention is made up of at least two sections releaseably coupled end to end. The end of one of the sections has, over a predetermined axial length, an internal perimeter substantially equal to the external perimeter of the end of the other section, so as to form a male end adapted to be inserted in a female end. The extreme margin of the male end includes a locking bead adapted to fit in sealed manner in an internal groove of the female end behind a locking b...
