Abstract:
A cord holding device and method of use. An embodiment of the device includes a sheet of material having a turned end. The turned end is selectively positionable between a closed orientation and an open orientation. In the open orientation, an opening is formed between the turned end and the sheet to allow for the cord to be inserted within an interior section. In the closed orientation, the turned end wraps around the cord to retain it within the device. A method of using the device comprises mounting the device to a position to receive the cord. A holding section is unturned an amount to allow for the cord to be inserted within the interior section of the holding section. After cord insertion, the holding section re-turns and wraps around the cord.

Abstract:
A foot support structure of the type used with a stilt includes a foot platform, a side wall, and first and second adjustable retaining members. The foot platform includes opposed first and second primary surfaces, a toe end, a heel end, and first and second sides. The side wall extends in a substantially normal direction from the first primary surface and extends along at least a portion of the first and second sides and a portion of the heel end of the base member. The front and rear adjustable retaining members are coupled to the side wall and extend between the first and second sides of the foot platform.
Abstract:
This invention relates to the immobilization of toxic materials, e.g., radioactive materials, in glass for extremely long periods of time. Toxic materials, such as radioactive wastes, which may be in the form of liquids, or solids dissolved or dispersed in liquids or gases, are deposited in a glass container which is heated to evaporate off non-radioactive volatile materials, if present; to decompose salts, such as nitrates, if any, and to drive off volatile non-radioactive decomposition products, and then to collapse the walls of said container on said radwaste and seal the container and immobilize the contained radwaste, and then burying the resulting product underground or at sea. In another embodiment, the glass container also contains glass particles, e.g., spheres or granules, on which the radwaste solids are deposited. In other embodiments, the glass container can be made of porous glass or non-porous glass, and/or the contained glass particles can be made of porous or non-porous glass or mixtures of porous or non-porous glass, and/or the glass container can be open at one end and closed at the other or open at both ends, and/or the glass container can be closed at one end with a porous or non-porous closure and open at the other end or closed at the other end with a porous closure. When a porous glass container and/or porous glass particles are used, the radwaste deposits within the pores of the glass which are closed during the subsequent heating step after non-radioactive volatiles have been driven off and prior to sealing the container. There results a substantially impervious glass article in which the radwaste is entrapped and which is highly resistant to leaching action. The products resulting from the use of porous glass, as the container, contents, or both, can be used as sources of radioactivity for a variety of applications in medicine, sterilization, food preservation and any other application where radiation can be beneficially employed.
Abstract:
A patient immobilization device for radiotherapy includes a one-piece composite body having a core and a carbon fiber reinforced skin encapsulating the core. The composite body further includes a posterior surface configured for mounting the composite body upon a radiotherapy support table, and an anterior surface defining a cradle. Positioning a patient upon the immobilization device and supporting the patient with the cradle enables emitting therapeutic radiation towards a craniospinal treatment site of the patient from a posterior side of the immobilization device while the patient is supported in a supine position. The emitted radiation may include proton beam radiation.
Abstract:
A system and method for designing an HVAC system using a database to manage values of properties corresponding to design elements. Elements include substantially all physical components and connections available for creating an HVAC system design. A user interface represents design elements arbitrarily selectable by a user and connectable to one another in a schematic to establish the HVAC system design. The system may provide, automatically, default values corresponding to the properties corresponding to the design elements. A user may select arbitrarily, from the design elements, an arbitrary number of selected design elements to be interconnected in the HVAC system design. A user may place and interconnect each arbitrary design element, while the system calculates, automatically, values of properties characterizing the arbitrary design elements; validating correctness of the interconnections and properties, calculating performance parameters, and providing drawings.

Abstract:
A deflector for use on an automatic molding machine deflects incoming sand downwardly onto the drag table and then upwardly into deep recesses in the pattern. The sand deflector is formed as a rectangular prism from a single block of metal, and has two deflecting channels separated by a strengthening septum. The channels are arranged at a predetermined angle in relation to the mounting surface of the deflector.
