An apparatus for continuously forming an extruded sheet product having an extruder assembly with a sheet die for delivering flowable material. A roll stand assembly has a main frame with first and second rolls. A vertical height positioning mechanism is operated to vary the relationship between the sheet die and nip location between rolls and has first and second lift components that cooperate with the main frame at first and second laterally spaced locations. The first and second lift components are each movable in first and second opposite paths to selectively elevate and lower the nip location relative to the sheet die. The vertical height positioning mechanism further has an actuating system to selectively and simultaneously cause the first and second lift components to move.

An earplug shaping device shapes a compressible earplug prior to insertion of the earplug into a user's ear canal. The device includes upper and lower structural elements which slidingly engage one another. Each of the upper and lower structural elements include a shaping surface. The shaping surfaces oppose one another and are inclined relative to one another. Various embodiments of the earplug shaper employ a slot in communication with a receiver which allows for the shaping of earplugs attached to a cord.

A reflexotherapy device to stimulate reflex points of the human body provides reliable and integral fastening of needles within an elastic base member to achieve a stable position of needles under any conditions of utilization of the device, and to carry out both static and dynamic impact on extensive areas of reflex zones. The device comprises elastic base member 1 with needles 2 fastened therein, each needle being provided with thickened end 3, and sharpened end 4 protruding from base member 1. In one embodiment the needles are fastened in the course of curing of the integral structure, and in another embodiment the position of needles 2 is fixed, so that thickened ends are disposed between two layers to be joined together.

A composite allograft press comprises a loading frame and a two piece mold to form an composite allograft and in particular an acetabular cup from impacted cancellous bone chips and cement. Pressure is applied by a manually operated lever through a rack-and-pinion gear mechanism to a plunger attached to one part of the mold. Compression load switches in-line with the plunger indicate the correct loading to the mold to produce a composite allograft in which the inner surface is smooth and comprised essentially of hardened bone cement material. The outer portion of the allograft may have limited cement extrusions but the exterior of the cup primarily shows exposed cancellous bone surface. In surgery a composite allograft; e.g., an acetabular cup, is fixed in the acetabulum with bone screws to fill an acetabular defect. A plastic liner is affixed with bone cement directly to the composite allograft cup to receive the femoral component.

Three-dimensional decorative articles are produced from blanks of heat-shrinkable plastic sheet material, using a mold base having an outer surface with a recess over which a blank is placed, and a convex mold insert that moves into the recess by gravity as the blank softens and cooperates with the interior wall of the recess to shape the sheet material into a three-dimensional decorative article. A guide peg extends outward from the bottom of the recess past the outer surface of the mold base and extends through a hole formed in the blank, and through a guide hole in the mold insert to support the mold insert before heating and to guide the mold insert as it moves into the recess of the mold base.

A press to form a composite acetabular allograft cup for use in hip replacement surgery is disclosed. The acetabular cup formed by the press comprises bone cement and cancellous bone chips. The press includes a two-piece mold for forming the acetabular cup. The mold is removable from the press and may be available in many different sizes to accommodate a range of patients. A screw-type compression means is utilized to force the acetabular cup into the desired shape. A compression gauge allows the operator to monitor the pressure applied as the acetabular cup is formed to prevent excessive crushing of cancellous bone chips. Breaking jaws are used to separate the acetabular cup from the upper portion of the mold after the bone cement has set and the acetabular cup is formed.

An improved process for sealing at least one ultracapacitor which includes a multi-layer structure is disclosed. The process includes the step of applying a substantial vacuum to press together an uppermost layer of the structure and a lowermost layer of the structure and to evacuate ambient gasses, wherein a sealant situated in a peripheral area between the facing surfaces of the layers forms a liquid-impermeable seal for the structure under the vacuum. In some embodiments, a press is used to apply pressure to the peripheral area on which the sealant is disposed. Usually, the ultracapacitor would be situated within an enclosable region of the press, and a collapsible membrane would be fastened over the ultracapacitor to fully enclose the region and transmit the vacuum force to the multi-layer structure. The force applied by the press itself causes the sealant to flow, thereby ensuring a complete seal upon curing of the sealant. This process can be employed to seal one ultracapacitor or a stack of at least two ultracapacitors. Another embodiment of this invention is directed to an apparatus for sealing a multi-layer ultracapacitor, comprising the elements described above.

A tool organizer and method of making the same is provided which allows a user to quickly and easily store tools and other items of various sizes, shapes and configurations. The customizable organizer includes a depressible core capable of maintaining an impression of an object that is pressed into it. The organizer also includes a covering material such as a fabric, flock or elastomeric coating, which protects the outer surface of the core, and also provides an aesthetically pleasing appearance. A tacky adhesive is applied on an upper surface of the core so that when a tool or other item is pressed into the covering material that overlay the core, the tacky adhesive maintains the covering material in close conformity to the customized impression of the tool or other item created in the organizer.
