Abstract: A wheelchair is provided for positioning and transporting patients. An exemplary embodiment of the wheelchair includes a tiltable seat frame portion and a base frame portion. The seat frame portion is generally configured to tilt relative to the base frame portion. An arcuate track adjustment portion generally permits pivotal adjustment of the focus about which the seat frame portion rotates. A seat frame adjustment portion generally permits pivotal adjustment of the seat frame portion relative to the base frame portion such that the seat frame portion maintains proper orientation with the base frame portion upon adjustment of the focus about which the seat frame portion rotates.

Abstract: A reciprocating piston liquid pump and piston driver mechanism includes a reciprocating piston liquid pump having a piston chamber and a piston reciprocating in the piston chamber from an unactuated position to an actuated position, with movement of the piston from the unactuated position to the actuated position causing the advancement of product. The piston driver mechanism includes a first driver member having an axis and a sloped circumferential surface extending along its axis, and a second driver member having an axis and a sloped circumferential surface extending along its axis. The first and second driver members are aligned along their axes and mate at an unactuated position along at least a portion of their sloped circumferential surfaces. Rotation of one of the driver members about its axis relative to the other of the driver members causes the second driver member to advance away from the first driver member toward an actuated position.

Abstract: A system, method and database design is provided for unifying data from a plurality of heterogeneous databases, each having business-context related data and a data access mechanism. A database is created (e.g., the UniDimNet) which contains a node for each dimension of an industry. For each data source which is accessible via the system, a set of data source specific dimensions is created and mapped to the corresponding industry business context dimension(s). A set of templates (e.g., UniViews) is created to query the data sources. Each UniView contains a specific question for a specific dimension designed for a specific data source. UniViews query the database they are associated with by using the data access mechanism of the associated database. A central server coordinates the system and facilitates use of the system through an interface (e.g., the UniViewer).

Abstract: Processes for controlling strength of an extracted beverage including providing a pseudo packed bed of an extractable beverage material and contacting at least one liquid extraction stream with the pseudo packed bed of beverage material at a selected depth to obtain at least one zone of minimum extraction and at least one zone of maximum extraction. As the depth at which the liquid extraction stream is introduced into the packed bed increases, the zone of minimum extraction increases and the zone of maximum extraction decreases.

Abstract: A storage enclosure includes a housing and first and second doors. The housing defines a front opening for permitting access to an interior of the housing. The first door is connected to the first and second side walls and is upwardly pivotable and inwardly slideable from a closed position covering a lower portion of the front opening to an open position uncovering the lower portion of the front opening. The second door is connected to the housing and is upwardly pivotable from a closed position covering an upper portion of the front opening to an open position uncovering the upper portion of the front opening.

Abstract: This light aeroplane at the same time fulfilled the weight limits for the European ultra light class or acolyte class as do at the same time for the US-American sport plan Category. It comprises an engine arranged at the nose and is provided with tractor airscrew and the cabin cell that is arranged behind the engine and is wide enough for two adjacent passenger seats. A central tube (1) with a 200 mm diameter extends forwards towards the engine and to the rear at least behind the front edge of the lateral rudder and elevator control. Everything else is constructed around said tube. A square profiled element (12) is transversally guided edgeways beneath the central tube (1) and is rigidly connected to the same in a positively engaged manner. An upwardly projecting tube bend (11), which arches over the length of the square profiled element is fixed to the rear side of the square profiled element (12) with the ends thereof. The level of a virtual plane cabin floor is defined above the square profile (12).

Abstract: The invention relates to topical pharmaceutical compositions comprising a phthalocyanine, wherein a diamagnetic metal ion moiety is either coordinated or covalently bound to the phthalocyanine core. The invention also relates to methods for destroying cancer tissue, precancerous cells, photo-aged cells, damaged cells, or otherwise pathologic cells, or activated cells, such as lymphocytes or other cells of the immune system, or activated or inflamed tissue cells comprising topically administering to the cancer tissue or surrounding tissue an effective amount of a phthalocyanine composition.

Abstract: An insulation element is provided for installation in a gap of thickness G provided between two objects. The insulation element includes a body made from a thermoplastic polymer material. The body has a first face, a second face and a thickness defined between the first and second faces. The body is characterized by a semi permanently pre-installation thickness T1 where T1 is less than G. The body swells upon heating to a thickness T2 where T2 is greater than or equal to G so that the insulation element bridges the gap, engages the two objects and provides a spring rate of between 4.0 and 275.0 grams per square inch.

Abstract: The invention relates to methods for amplifying, modifying, mutating and cloning DNA of any size. These methods comprise a series of PCR reactions, which are punctuated by ligation reactions.

Abstract: An antomizing foam pump creates atomized droplets of a foamable liquid in air in a compression chamber. The compression chamber is then collapsed to force the droplets and air through a mesh screen to create a foam product.

Abstract: Ejector devices and systems are provided, that entrain ambient air within a primary stream of pressurized air, for use in a variety of applications including aircraft, buildings and other stationary structures. The ejector draws ambient air through an air treatment means such as a filter before its entrainment within the primary stream. The combined streams are then delivered to a ventilation system, an air curtain or other suitable recipient of treated, thermally conditioned air. The systems include diffusers, air curtain systems and variable air volume ventilation systems for aircraft and other vehicles.

Abstract: Water permeable membranes and methods of forming water permeable membranes are provided. The water permeable membranes are comprised of a cross-linked polyamide containing at least one bifunctional additive that is hydrophilic and reactive. Additionally, in accordance with other embodiments of this invention, methods of forming water permeable membranes comprised of a cross-linked polyamide containing at least one bifunctional additive that is hydrophilic and reactive are provided. Specifically, the water permeable membranes may comprise a membrane formed from a cross-linked aromatic or aromatic/aliphatic polyamide interfacially polymerized on a porous support. The presence of the at least one hydrophilic and reactive additive improves the flux and salt retention properties of the membrane in comparison to a membrane formed without the at least one hydrophilic and reactive additive.
