Abstract: A method of controlling a roll gap between first and second work rolls (102, 104) that includes defining a plurality of work surface locations spaced apart along the first work roll (102) in the longitudinal direction; obtaining a radius of the work surface (102a) of the first work roll (102) at each of the work surface locations; based on the radii of the work surface locations, obtaining a longitudinal profile of the work surface (102a); based on the longitudinal profile, tilting the first work roll (102) relative to the second work roll (104) in the common plane in order to reduce a difference in the average size of the gap either side of a centerline (CL), which bisects the longitudinal axes of the first and second work rolls (102, 104).

Abstract: An electrical assembly including a grounding mechanism and an electrical device, the grounding mechanism including a support longitudinal member and a switch contact member, the switch contact member arranged in or on the support longitudinal member, the switch contact member configured to be connected in use to ground, the electrical device including an electrical terminal, wherein the support longitudinal member is configured to be slidable between: a first position in which the switch contact member is separated from the electrical terminal so that the switch contact member is electrically disconnected from the electrical device and a second position in which the switch contact member is in contact with the electrical terminal so that the switch contact member is electrically connected to the electrical device.

Abstract: The present invention is directed to a vape device configured to determine the dose of a payload delivered to a user during each of a plurality of user inhalations. In a first embodiment, the vape device tracks the energy used to vaporize a portion of the payload during user inhalation to determine the dose. In a second embodiment, the vape device measures the temperature at multiple locations within the air flow chamber during user inhalation to determine the dose. In a third embodiment, the vape device measures the intensity of light that is transmitted through the vaporized payload, reflected off the vaporized payload, or transmitted through a light transmitting medium positioned within the vaporized payload, during user inhalation to determine the dose.

Abstract: A method, system, and medium related to data retrieval using tags and routing rules to optimize the data retrieved and the response time for the data retrieval by decreasing the latency of the response and by increasing the efficacy of the dynamic content delivery is provided. A message request is received from a client server. A local server determines if the digital content resides on a local server by comparing a tagged rule for the message request with a tagged rule associated with the local server. If the local server determines, by comparing the tagged rules, that the digital content does not reside on the local server, the local server sends the message request for the digital content to a service server. The service server then parses the tagged rule associated with the message request into a set of tree-based hierarchical tagged rules.

Abstract: An apparatus and related method for mixing and/or applying a cementitious product. The apparatus includes a container for holding a cementitious product, a pump for delivering the cementitious product from the container to an applicator head, and an applicator head for shaping and applying the cementitious product to a surface so as to have a desired thickness and contour.

Abstract: Systems and methods are provided for performing a surgical procedure on a beating heart of a patient. Methods are provided which include positioning an end effector in close proximity to a surgical site on the heart, the end effector being mounted on a robotically controlled arm. The motion of the surgical site is monitored and end effector tracking command signals computed in response to the monitored motion of the surgical site. The tracking command signals are forwarded to actuators operatively associated with the robotically controlled arm to cause the arm to move the end effector generally to track motion of the surgical site. The method further includes inputting an end effector movement command signal, and forwarding the end effector movement command signal to the actuators to cause the end effector to move relative to the surgical site so as to perform at least part of the surgical procedure.

Abstract: The present invention relates to an unleaded durable transparent vitreous glass composition comprising a combination of(a) up to 98 wt % of a low alumina alkali borosilicate,(b) 2-20 wt % of a major addition of one element selected from the group of zirconium, tin and titanium, and(c) less than 10 wt % of at least one element selected from bismuth, barium, strontium, zinc, lanthanum, molybdenum, cerium and/or a fluoride containing inorganic compound wherein the amounts of (a), (b) and (c) are calculated on the basis of the total amount of the oxide forms of (a), (b) and (c),a process for its production and the use of said composition.

Abstract: Impurity streams generated during the metallurgy of copper are hydrometallurgically processed at ambient pressure for recovery of primary values in an energy-efficient manner and with the capture and conversion of metallic impurities to states that are acceptable for disposal into the environment. Hallmark features of the various embodiments of this invention include the water leach of flue dust, a controlled acid leach stage in which metal species are solubilized, the extraction of copper as a sulfide, and the ability to operate the various process stages at essentially ambient pressure.

Abstract: Impurity streams generated during the pyrometallurgy of copper are hydrometallurgically processed at ambient pressure for recovery of primary values in an energy-efficient manner and with the capture and conversion of metallic impurities to states that are acceptable for disposal into the environment. Hallmark features of the various embodiments of this invention include the water leach of flue dust, the extraction of water-soluble copper as a separate product, a controlled acid leach stage in which bismuth is solubilized, the return of copper to the smelting process as a sulfide, the ability to operate the various process stages at essentially ambient pressure, and the gradual reduction in temperature over the course of the process without the use of indirect heating or cooling operations.

Abstract: A method for the production of full or partial dental restorations including veneers, crowns, inlays, onlays, and bridge structures, and dental restorations produced by the method. The method utilizes the technique of flame spraying to form a basal layer of a technical ceramic based material upon which porcelains are applied to produce a strong, aesthetically acceptable and custom made dental restoration. The technical ceramic based material may be Alumina, Zirconia, Titania, or combinations thereof, and the flame spraying may be a direct method or an indirect method. The technical ceramic based material may include small amounts of silicate based materials.
