Abstract: A medication sprayer (2) is used to spray a liquid medication (110) directly from a vial (4) having a needle pierceable septum (6). The sprayer includes a body (10) reciprocally housing the vial. A spike assembly (60) includes an air inlet spike (66), connected to the ambient environment (108), and a liquid exit spike (68), both piercing the septum. The liquid exit spike is fluidly coupled to a piston/cylinder arrangement (88, 26, 36) having a combination piston/flapper valve (88) at one end of the cylinder (26) and a supplemental check valve (36) at the other end. The vial, spike assembly and piston/flapper valve move in unison to pump liquid through the piston/flapper valve into the cylinder, to pull air into the vial and to pump liquid in the cylinder through the supplemental check valve, past a spray nozzle (44) and into the ambient environment.

Abstract: A position detecting apparatus includes a tablet and a position pointer. The tablet includes a plurality of electromagnetic wave generating/detecting apparatus. The generating/detecting apparatus generates an electromagnetic wave at specified points of time and detects electromagnetic wave at different points of time. The electromagnetic wave generating/detecting apparatus includes a first coil of a first direction with a first inductance value and a second coil of a second direction with a second inductance value. The first and second coils are coupled serially and closely adjacent to each other and the first inductance value is substantially equal to the second inductance value. Only the first coil is enabled when the electromagnetic wave generating/detecting apparatus is generating the electromagnetic wave, the first and second coils are both enabled when the electromagnetic wave generating/detecting apparatus is receiving the electromagnetic wave.

Abstract: Transgenic mice having a phenotype characterized by the substantial absence of mature T lymphocytes otherwise naturally occurring in said mice. The phenotype is conferred in the transgenic mouse by a transgene contained in at least the precursor stem cell of the T lymphocyte which is depleted. The transgene comprises a DNA sequence encoding a T cell receptor polypeptide variant which inhibits maturation of the T lymphocyte.

Abstract: A thermal ablation catheter includes an elongate body member having a heating element disposed over a predetermined length of its distal end. The heating element is suspended away from an exterior surface of the elongate member to form a circulation region thereunder. Thermally conductive fluid can be introduced through a lumen in the elongate member and distributed within the circulation region to improve heat transfer. The catheter is used to introduce the thermally conductive medium to a hollow body organ where the heating element raises the temperature of the medium sufficiently to induce injury to the lining of the organ. Optionally, an introducer sheath having an expandable cage at its distal end may be used in combination with a thermal ablation catheter. The expandable cage helps center the heating element on the catheter within the body organ and prevents direct contact between the heating element and the wall of the organ.

Abstract: An assembly of a bolt, a washer, a nut and locking structure for locking the bolt against rotation after the bolt, washer and nut have locked together a pair of flat, plate-like members in frictional engagement with each other. Any tendency for the bolt to rotate in a reverse direction will be prevented by the locking means. The plate members will essentially be bonded together against movement relative to each other, thereby maintaining structural integrity of the assembly. In a first embodiment, the head of the bolt has a notch for receiving one end of split ring washer. The other end of the washer is in a notch in the nut. The nut and washer define a locking unit for preventing reverse rotation of the bolt after the head of the bolt has been moved into proximity with the washer and the washer has been moved into the notch of the nut. Other embodiments are disclosed.

Then the bars are separated into elements. The second substrate is positioned over the elements and fixed to the elements to complete the manufacture of the TEM.

Abstract: An excavating tooth includes an aperture for bolting the tooth to a shank plate and a lug configured to provide a friction fit in a recess formed in the shank plate. The bolt and lug combination prevent relative movement between the tooth and shank plate. In addition, tooth load is absorbed in the shank plate through the connection between the lug and shank plate, thereby reducing the stress transferred through the bolt.

Abstract: A new tomato cultivar is provided which is homozygous for a genetically fixable recessive genetic factor which confers the ability to bear fruit that accumulate sucrose. The increased sucrose content, in turn, leads to a higher total soluble solids content in the mature fruit. Higher total soluble solids in tomato fruit are of particular importance to the tomato processing industry. A method for producing the claimed cultivar is also provided.The claimed genetic factor can be derived from any Lycopersicon species which accumulates sucrose in the mature fruit. Once genetically fixed in a tomato cultivar, the factor can be transmitted to other plants in a predictable manner.

Abstract: A series-shed loom for weaving a fabric from warp threads and weft threads. The loom has a rotor with reeds that comb through the warp threads and carries guide elements which define high points and low points. A multiplicity of elongated laying elements oriented parallel to the axis of rotation of the rotor guide the warp threads towards the rotor and insert them in the high and low points of the guide elements thereon. The laying elements are spaced from the rotor surface, they have a width in the direction of rotation, and warp threads which are adjacent in the fabric are guided over laying elements which are separated from each other by a pitch of at least twice the pitch between adjacent laying elements so that a point of intersection between the warp threads which are adjacent in the fabric is moved relatively further away from the laying elements and so that the point of intersection is further moved closer towards the rotor.

Abstract: The press guide roll (15) or web guide roll (4) comprises a fiber-reinforced plastic roll tube (20; 6) and a wire layer (7) wound on the surface of the roll tube (20; 6) in order to form substantially peripherally directed grooves (17). On either side of the roll middle (M), complementary sections (7b, 7c) of the windings (7) are inclined slightly relative to the peripheral direction and thus form a wire layer which is mirror symmetrically disposed about the roll's middle plane (M). The web guide roll (4) therefore laterally guides and automatically centers the material web.

Abstract: A testing method for active matrix liquid crystal display substrates having thin film transistors provided with a plurality of pixel electrodes, a plurality of source lines, and a plurality of gate lines formed on a substrate. A high resolution electro-optical element whose optical properties change when an electrical field is impressed on it is disposed above the active matrix liquid crystal display substrate and separated therefrom by an extremely small gap. Electric current is caused to flow between the pixel electrodes on the active matrix liquid crystal display substrate and the transparent thin film electrodes on the surface of the electro-optical element, creating an electrical field in the electro-optical element. By detecting local changes in the optical properties of the electro-optical element, defects in the pixels of the active matrix liquid crystal display substrate can be detected.

Abstract: Peptides which bind to selected receptors are identified by screening libraries which encode a random or controlled collection of amino acids. Peptides encoded by the libraries are expressed as fusion proteins of bacteriophage coat proteins, and bacteriophage are then screened against the receptors of interest. Peptides having a wide variety of uses, such as therapeutic or diagnostic reagents, may thus be identified without any prior information on the structure of the expected ligand or receptor.
