Abstract: A switch matrix is disclosed for keypads used in devices such as primary control points for automation systems in homes vehicles, or businesses. The switch matrix preferably includes a support frame for supporting a grid of key positioning members arranged in a series of rows and columns. The key positioning members each preferably include cantilevers which can be deflected by pressing the keys to activate switches associated with the keypad. The cantilevers preferably have knobs which are received in corresponding openings in the keys so that the keys can be removably attached to the cantilevers with a compression fit. This allows keys of different sizes and shapes to be easily attached to the keypad in various configurations without the need for different attaching devices for each situation.
Abstract: Polysaccharides, which are widely used as an anticoagulation drugs, especially heparin, are clinically administered only by intravenous or subcutaneous injection because of their strong hydrophilicity and high negative charge. Amphiphilic heparin derivatives were synthesized by conjugation to bile acids, sterols, and alkanoic acids, respectively. These heparin derivatives were slightly hydrophobic, exhibited good solubility in water, and have high anticoagulation activity. These slightly hydrophobic heparin derivatives are efficiently absorbed in the gastrointestinal tract and can be used in oral dosage forms. Methods of using these amphiphilic heparin derivatives and similarly modified macromolecules for oral administration are also disclosed.

Abstract: A system for parking automobiles in a garage which uses a single-drive mechanism to simultaneously move automobile platforms. The automobile platforms reside in contiguous storage towers and are stacked in multiple levels. The automobile platforms simultaneously move in the towers. In one tower, the platforms move upward while the platforms in the other tower move downward. The automobile platforms rest on movement chains which move vertically among the various levels. The automobile platforms are moved from the vertical movement chains to a lateral movement means to move horizontally from tower to tower. The vertical movement system is powered by single-drive mechanism through a series of gears, sprockets and chains. Horizontal movement in the upper and lower lateral transfer areas is done by a lateral movement means.
Abstract: A pool cover system including a pool cover collecting drum supported for rotation on its ends and a drive gear connected to the drum by a drive shaft. A power gear is operably connected to a portable electric drill by a power shaft, engaging the drive gear. Upon activation of the drill, the collecting drum rotates retracting the pool cover. A complementary apparatus on the same side of the pool, such as a rope reel collecting apparatus having an engageable drive gear and a drive shaft connected to a reel, extends the pool cover over the pool by pulling on a rope attached to a rigid end of the pool cover. The pool cover is extended and retracted with the sides sliding in one channel of a dual channel track, allowing the cover to serve as a safety cover.
Abstract: A method for generating and amplifying closed circular DNA having a specific sequence in vitro in a cell-free system is disclosed. Prior to the invention of this method, closed circular DNA could only be amplified in vivo in appropriate host cells. The essence of the method is the inclusion of a thermostable DNA ligase in a PCR reaction. This procedure is referred to as ligation-during-amplification (LDA), in which the fully extended DNA strands are ligated by the DNA ligase and used as templates for subsequent amplification. Closed circular DNA having a specific sequence can be selectively amplified exponentially by the use of two sequence-specific primers in the LDA reaction. In addition, one or more site-specific mutations can be introduced into a closed circular DNA by the use of one or more mutagenic primers in the LDA reaction. Various thermostable DNA polymerases and thermostable ligases can be used for LDA amplification.

Abstract: A textured whey protein product for use as a meat extender or meat analog is prepared by thermoplastic extrusion of a composition containing whey protein concentrate and optionally an edible polysaccharide, such as cornstarch. Puffing of the extruded product results in a snack food product. Methods of making the meat extender product and the snack food product are also included.
Abstract: A variable-ratio transmission device. A first translational member is pivotally intercoupled to a first rotational member by at least one connecting arm. The connecting arm has a first portion pivotally connected to the first translational member at a first pivot point, and a second portion pivotally and adjustably connected to the first rotational member at a first radial attachment point removed from the center of rotation of the first rotational member. The first radial attachment point and the center of rotation thereby define a first attachment radius. The location of the first radial attachment point with respect to the first rotational member is variable to thereby increase and decrease the first attachment radius, which in turn modifies a ratio of movement between the first rotational member and the first translational member.
Abstract: Formulations for enhanced mucosal absorption of heparin are disclosed. In one embodiment, a powdered heparin composition is made by dissolving an amphiphilic heparin derivative including heparin covalently bonded to a hydrophobic agent in a water phase, dispersing the water phase in an organic phase such that an emulsion is formed, and drying the emulsion. In another embodiment, an amorphiphilic heparin derivative dispersed in an oil phase is made by dissolving the amphiphilic heparin derivative in water or a water/organic co-solvent, dispersing the water or co-solvent in the oil phase, and evaporating the water or co-solvent. In another embodiment, heparin-containing nanoparticles having surfactant molecules associated with a hydrophobic agent on the outside of the nanoparticles are made by dissolving the amphiphilic heparin derivative in an aqueous solvent, mixing the surfactant with the aqueous solvent, and disrupting nanoparticles of the amphiphilic heparin derivative.
Abstract: A method for making a directed antisense library against a target transcript is described. A cDNA of the target transcript is cloned in an appropriate cloning vector. Next, a plurality of deletion derivatives of the cloned cDNA is prepared such that the deletions serially extend into the cDNA from one end thereof. The resulting deletion library is then treated such that cDNA is removed from the other end of each cDNA insert, thus obtaining a fragment library having fragments of a selected size. A catalytic core is then inserted into each fragment of the fragment library, resulting in the directed antisense library. An illustrative antisense gene in the hammerhead ribozyme catalytic core. Plasmids for making the antisense library, plasmids and methods for making the fragment library, and a method for identifying target sites for antisense-mediated gene inhibition are also described.
