A sensor includes at least two electrodes, and at least one nanowire extending substantially laterally between the electrodes. The at least one nanowire has at least two segments with a junction or connection formed therebetween. A sensing material changeable between at least two states is positioned adjacent to the junction or connection, and adjacent to at least a portion of each of the segments.

Disclosed herein is a method for making an item of jewelry. The method includes the steps of providing a chain comprising a plurality of links; providing at least one bead having an opening defined therethrough; providing a press having a support member, a hammer, and at least one pin; positioning the bead on the chain; resting the bead on the support member; positioning a first link on the at least one pin; and actuating the press, whereby the first link is widened. In a preferred embodiment th...

The invention relates to composite articles comprising a substrate and additional layers on the substrate. According to one example, the layers are selected so that the difference in the coefficient of thermal expansion (CTE) between the substrate and a first layer on one side of the substrate is substantially equal to the CTE difference between the substrate and a second layer on the other side of the substrate. The stress caused by the CTE difference and/or shrinkage on one side of the substra...

The present invention related to a method of producing polypeptides in transformed host cells by expressing a precursor molecule of the desired polypeptide which are to be acylated in a subsequent in vitro step. The invention is also related to DNA-sequences, vectors and transformed host cells for use in the claimed method. Further, the present invention is related to certain precursors of the desired polypeptides and certain acylation methods. The invention provides a method for making polypept...

The invention provides a process for dynamic vulcanization comprising grafting organic silane on disperse phase component, thereby introducing chains into the component which are cross-linkable in the presence of cross-linking agents when the component is molten. The invention further provides thermoplastic vulcanizates having superior properties, including high flexibility and impact resistance, low hygroscopicity, non-toxicity, and excellent processability.

Drainage elements are made by delivering loose fill elements under gravity from a container into a sleeve of netting that is tied at one end to a pipe, or other endless element, that is passing through the container. The sleeve of netting is supplied from an apertured cage extending below the container. In one embodiment a blower and chute arrangement is used to blow air downwardly into the drainage element being formed to increase the rate of flow of the loose fill elements into the sleeve of n...

A simplified process for the one-pot preparation of aztreonam, using azetidine and TAEM as starting materials, without the intermediary separation of t-butyl-aztreonam is provided.

Disclosed herein is a downhole valve. The downhole valve includes, a flapper seat, a flapper sealable against the flapper seat, a spring housing in axial alignment with the flapper seat and a metal-to-metal seal disposed between the flapper seat and the spring housing. The metal-to-metal seal is sealable to both the flapper seat and the spring housing when in an energized position. Additionally, the metal-to-metal seal is a separate component from both the flapper seat and the spring housing.

A drink making machine (10) includes an ice shaving and dispensing unit (11) which provides a predetermined amount of ice, by weight, through a chute (21) to the pitcher (17) of a blending unit (12). A nozzle (30) is carried by the chute (12) and provides water through a nozzle opening (41) until a predetermined amount of water, by weight, is received by the pitcher (14). The water from the opening (41) is not allowed to directly impinge against the bottom of the pitcher (17). The water from the...

A method for making a wrench includes a step of making a mediate member, a movable jaw and an adjusting member, a step of applying heat treatment to the mediate member, the movable jaw and the adjusting member, a step of cleaning respective surfaces of the mediate member, the movable jaw and the adjusting member, and coating a anti-rusting layer on the mediate member, the movable jaw and the adjusting member, and a step of combination to put the mediate member in a mold and making a body by way ...
