Abstract:
A method of making a fused silica article having a combined concentration of protium and deuterium in a range from about 1×1016 molecules/cm3 up to about 6×1019 molecules/cm3. In some embodiments, deuterium is present in an amount greater than its natural isotopic abundance. The method includes the steps of providing a fused silica boule, diffusing at least one of protium and deuterium into the boule, and annealing the boule to form the fused silica article. A method of diffusing hydrogen into fused silica and a fused silica article loaded with hydrogen formed by the method are also described.

Abstract:
A system and method for inscribing an item is provided. The system includes a housing having a door, an inscriber, and a support. The inscriber is disposed in the housing and is operable to inscribe the surface of an item secured in an item carrier. The support has a positioning structure that is configured to engage the item carrier and establish a reference point so that the location of the surface of the item with respect to the support is determinable. The support moves between a loading position and an inscribing position to position the item for inscribing. There is also provided a controller that governs the movements of the inscriber and includes an input device. The input device is moveable between a first position to receive characteristics about the item to be inscribed and a second position to receive a message to be inscribed on the surface of the item. There is further provided an item carrier that is configured to securely hold an item to be inscribed and includes a second positioning structure. The second positioning structure is engageable with the first positioning structure of the inscribing device to position the item carrier and item on the support of the inscribing device so that an inscription inscribed on the item will be correctly orientated on the item.
Abstract:
An apparatus for dispensing unpackaged articles includes a guide shaft to carry the articles, a pushing element that advances the plurality of articles along the guide shaft, and a feed screw engagable with the pushing element and driven by a motor. While the articles to be dispensed are moved collectively as a group, the apparatus provides for the controlled dispensing of individual articles. A sensor is provided to identify when an article has been dispensed and to subsequently stop movement of the plurality of articles. Also, an iris including a yieldable opening sized to allow passage therethrough of an article in a staggered manner is provided to facilitate the individual dispensing of articles and to prevent the inadvertent dispensing of articles.
Abstract:
A continuous variable clutch is provided. The continuous variable clutch includes a first sheave member and a second sheave member. The first sheave member includes a first central hub and a first conical-faced surface extending radially from the first central hub. The second sheave member includes a second central hub and a second conical-faced surface that extends radially from the second central hub. The second central hub of the second sheave member is received in a cavity of the first central hub such that the first conical-faced surface of the first sheave member facing the second conical-faced surface of the second sheave portion. The second central hub moving axially within the first central hub based on an amount of torque on the continuous variable clutch. The first sheave member and the second sheave member further forming a central passage to receive an input shaft of a transmission.
