Abstract: The invention is a filter for gaseous media in which nano alumina fibers and second fibers are arranged in a matrix to create asymmetrical pores. The filter is a high efficiency, high capacity particulate filter that intercepts pathogens and other particulate matter from gaseous media, including vapor-suspended particles. The new filter has an improved retention of water-aerosolized particles as compared to conventional HEPA filters and may be used as a pre-filter that extends the life of HEPA filters by about five to ten times. The invention is also a method of manufacturing and using the filter.

Abstract: An improved system and method for building security and occupant safety wherein a digital image of plan view of a selected floor of a building is prepared from a physical drawing. The digital image shows the substantial architectural features of the building, including external walls (10) and internal walls (12). In the digital image, the building floor is divided into several zones (14) and each of the zones is broken into segments (16). Each of the segments (16) is identified by alpha/numeric characters or other symbols by which emergency responders or other building occupants can navigate the building.

Abstract: A flexible conveyor belt (10) has a plurality of transverse rods (11) on which a plurality of links are mounted for rotational and longitudinal movement on the rods. The links include edge links (12a, 12b) at opposite edges of the belt and link modules (13a, 13b and 15) positioned between the edge links. The rods have radially enlarged heads or buttons (16) on their ends, and the edge links have a cavity (29) for receiving the head, and an undercut shoulder (36) against which the head abuts to retain the edge link at the end of the rod. The link modules have a leading end (41) and a trailing end (42), and the trailing end of at least module (15) has slotted openings (47, 44) to enable the trailing end to be detachably connected to an associated rod.

Abstract: The elevating device of the present invention is comprised of first, second, and third dovetail members that are interlockingly engaged. First dovetail member is secured to an object or an independent surface such as a tree or a ladder. First and second dovetail members are stationary and third dovetail member is moveable. Slide bars are secured to third dovetail member. Slide bars slidably engage a guide track. There is a gear that engages slots in the second dovetail member elevating third dovetail member as the slide bars slidably engage the guide track. There is a platform for holding people or objects that is secured to third dovetail member. As the gear rotates and elevates third dovetail member, the platform secured thereto is also elevated.

Abstract: The invention relates to a case for holding elongate objects, in particular, drills or other tools, comprising a housing shell and a lid hinged pivotably thereto via a hinge and at least two pivotable holding parts which while the case is closed are pivoted inward into the interior, while they are pivoted outward out of the said interior when the lid is being opened, wherein only the holding part close to the lid is mounted in a pivoting axis in the housing shell of the case, while the at least one additional holding part disposed in front of the holding part closest to the lid is detachably connected to the respective closest holding part. The advantage lies in the fact that the case can be modularly expanded, that the manipulation is improved, and that the manufacturing cost is reduced.

Abstract: A plastic waste container is rotationally molded with a hollow material carrying or holding compartment having a bottom, rear, front and opposed side walls. A plastic pocket defining a prong receiving channel, located on each side wall, is integrally formed with the compartment, i.e., molded therewith or premolded and subsequently bonded thereto. Preferably a skirt, extending around each of the pockets, is integrally molded with the compartment and includes struts extending along the side walls of the compartment, above and below the pockets.

Abstract: An apparatus for strengthening hand, wrist, forearm, and shoulder muscles, thereby increasing performance and reducing the risk of injury in sports that utilize a swinging motion, such as golf, tennis, or baseball. The apparatus is also used to rehabilitate injured muscles and connective tissue in the wrist, forearm, and shoulder. The apparatus consists of two cam assemblies connected to a extensible support that has an adjustable height. The cam assemblies are adjustable relative to the coronal plane of the player's body and each comprises a support, a rotatable cam, a handle, and a resistive band. Each handle is adjustable relative to the sagittal plane of the player's body. The ability to adjust the apparatus in three planes means that a player is able to focus on the development of sport-specific muscles by adjusting the apparatus to mimic the swing used for a particular sport.

Abstract: The invention comprises a retractable cover system comprising: a flexible cover. A plurality of supporting bows support the cover. A semi-rigid member having first and second ends is secured to the cover section. The semi-rigid member is capable of flexing laterally outward if the system is retracted. This outward action allows the cover or cover sections to consistently fold in the same way and prevents the cover or cover sections from getting caught in the load or in the cover system componentry. The invention also comprises a segmented tube secured to the bottom portion of the cover between the bows.

Abstract: The invention provides a method using matrix transformations of the three coordinate systems used in radiotherapy to correct for any deviation between a planned dosimetric treatment target and the actual location of the treatment target.

Abstract: A composition for effecting heat transfer to or from a fluid, the composition comprising a primary adsorbent material, such as activated carbon, for adsorption of a gas, such as carbon dioxide, and a graphite material in an amount of 0.01 to 80% by weight of the total composition. A binder may also be included in the composition to aid heat transfer. The composition may be incorporated into an apparatus (12) that includes sealing means (14) for retaining the gas on the surface of the material and a release mechanism (16) for breakage of the seal, said apparatus being provided with a vessel (6) for holding fluid.

Abstract: A scraper for removing deposits from the exterior of a tubular member which has a plurality of concatenated, resilient segments adapted to contact the exterior surface of the tubular member where each pair of adjacent segments is connected through a geniculation. The resilient segments are aligned with and interposed between a pair of opposing annular disks that are connected together by a plurality of spacers located adjacent to the outer periphery of the disks and adjacent to the chords of the segments. The chords of the segments are distributed around the circumference of the axial openings such that the various segments are deformed outwardly, whereby the resilience of the thus deformed segment urges it inwardly against the tubular member, and causes it to clean the tubular member as the scraper moves axially.
