The sidewall strip is secured in position by bending the sidewall strip to form one of a circle or an oval, and then engaging the first engagement and the second engagement with the slotted engagement of the base, and then engaging the first engagement and the second engagement with the slotted engagement of the top cap.

Abstract: In one embodiment, a method for treating an infected implant area of a knee joint comprises surgically accessing the implant area, and inserting a tibial component into the tibia using an antibiotic-impregnated material. A femoral component is formed that is configured to interact with the tibial component by stable knee joint articulation and motion. The femoral component is formed of an antibiotic-impregnated material using a mold. The femoral component is attached to the femur using an antibiotic-impregnated material, and the tibial component is interfaced with the femoral component to form a stable temporary knee joint capable of reducing the spread of infection while permitting movement of the knee joint.

Abstract: Synclastic hollow core building panels are employed to form dome-like structures. The synclastic curve allows the panels to be lightweight, yet capable of carrying the weight of the structural loads. When combined, the panels create a sphere or a section of a sphere for enclosing space, with optional egress, skylight, and foundation portals incorporated into the structure without disturbing the spherical curvature of the interior or exterior surfaces. The spheres or sphere sections require no additional framing; the panels themselves are the frame. Workers with only the basic assembly skills can construct a sphere or sphere sections using these panels.

Abstract: An igloo building block mold comprises a shell defining a pair of generally cuboid mold portions. The mold portions are offset from one another in both an upright direction extending between the top and bottom ends of the mold portions and a lateral direction extending between the end walls of each mold portion. A building block formed by the mold, when stacked on a previous row of blocks, permits inter-engagement between the blocks due to a shoulder being formed on each block which engages the corresponding shoulder of a previous block supported therebelow. The offset in the lateral direction permits side edges of each block to be inter-engaged with adjacent blocks as the blocks are placed in the desired position in the igloo structure during construction.

Grasping zones are disposed along the rim and the grasping zones have sufficient dimensions to permit control of the geometry of the rim and also to permit control of the horizontal positions of the two grasping zones.

Abstract: Disclosed is a method whereby a narrowed part similar to an actual lesioned blood vessel can be easily obtained. A mold (10) comprises first and second molded members (16, 17) having inner spaces (29, 40, 57) passing through in the axial direction and an axial member (18) detachably inserted through the individual inner spaces (29, 40, 57) of the individual molded members (16, 17). The molded members (16, 17) have tapered front parts (27, 27) respectively. In the state of facing the front ends (20) of the tapered front parts (27) to each other and thus forming a concave (12), the axial member (18) is attached. A first material (75) made of a mixed material comprising calcium carbonate or the like and silicone or the like is applied to the concave (12). A second material (76) such as silicone is applied to the entire outer periphery of the mold (10). After hardening the materials (75, 76), the mold (10) is withdrawn by detaching the axial member (18) and dividing the concave (12).

The lower mold portion includes a cutout disposed along a parting line defined between the lower mold portion and the upper mold portion and opening onto the cavity. After introduction of a ceramic slurry mixture into the mold the upper mold portion is removable, to expose a first side of the core and a protective flash formed in the cutout. Desirably, a heat shield is positioned over the protective flash and the exposed portion of the parting line of the lower mold portion so that the lower mold portion is not exposed directly to a flame during a preliminary firing to impart sufficient strength to the ceramic core so that the ceramic core may be handled.

Abstract: An apparatus and method for casting lens without using a gasket that can be used to form all powers and geometric shapes of lenses. An elastomeric strip is used to wrap around the edges of two molds to form a sleeve-like structure, which in turn cooperates with the molds to form a molding cavity. Moreover, this sleeve-like structure does not crumple or shrink during the lens polymerization process. Instead, it allows the molds to slide axially within it to compensate for any shrinkage that occurs during the lens polymerization process.

Abstract: Formwork for surfaces varying in curvature has a face sheet adjustable with respect to its curvature, girders supporting the face sheet and applied to the girders, in spaced relationship to the face sheet, there is a boom system which is composed of individual boom members bridging the girders and is suitably attached to the girders at the outsides thereof averted from the face sheet. Adjustment of the curvature of the face sheet is carried out by altering the effective length of the boom members between the girders. The mutually opposed formwork elements are adapted to be braced together by means of formwork anchor ties. A crosspiece in the form of a boom member is applied to a formwork element at at least two girders and simultaneously serves as an abutment for the formwork anchor tie, the latter therefore being arranged between and having its reaction forces transferred to the two girders.

Abstract: A method of making a solid core locatable between a wheel rim and a tire fitted to the rim, includes introducing a foamable composition into a mould cavity having a substantially inflexible mould surface. The cavity is suitably shaped so that a core locatable between a wheel rim and a tire fitted to the rim can be moulded therein. The composition is allowed to foam, thereby to fill the mould cavity. Air and excess composition is allowed to vent from the cavity via an elongate vent slit extending along a major portion of the cavity. The foamed core thus moulded in the cavity is removed from the cavity on the composition having set at least partially.

Abstract: An elongate packing is sandwiched between two sheet-like mold members in an encircling manner to define a mold cavity therebetween, then a thermosetting plastic material is poured into the mold cavity, and the thermosetting plastic material is heated and set in the mold cavity. The upper and lower mold members are held against deformation transverse thereof so as not to be deformed by the shrinkage of the thermosetting plastic material when the latter is set, and the packing is allowed to move transversely thereof for following the shrinkage of the thermosetting plastic material when the latter is set. In some embodiments, the packing comprises a packing body adapted to be sandwiched between the mold members for preventing the plastic material from flowing out of the mold cavity with a flange joined to the packing body and adapted to be held against peripheral edges of the mold members.
