Title: Method for marking an optical element
Inventor: TARUMI NIRO
IPC: B41M5/00
Filed: 1979-12-11
Granted: 1982-10-05
Abstract: ABSTRACT OF THE DISCLOSURE       A method for marking an optical element comprising the incorporation of a fluorescent dye-stuff in the whole or a part of an optical element formed from plastics material.  The dye-stuff may be incorporated in the molten plastics material from which the optical element is formed.  The dye-stuff may instead be dissolved in water and the optical element dyed by immersion in the solution, which may optionally contain a surfactant.  Alternatively the dye-stuff may be dissolved in alcohol and markings printed onto the optical element using a rubber stamp, the element being subsequently dried to encou-rage absorption of the dye-stuff by the lens.  The concentra-tion of the dye-stuff incorporated is regulated so that under normal sunlight or room lighting the marked optical elements do not appear different from unmarked ones, but under ultra-violet light the marks become visible.  Optical elements, such as lenses, thus marked do not have transmission rate curves substantially different from those which are untreated.

Abstract: Disposable Clip Applier Abstract A disposable instrument for applying surgical clips consisting of a clip applier and a cartridge mounted thereon.  The instrument consists of a housing having a body portion and an elongated sleeve portion extending from the front of the body portion.  Disposed for rectilinear movement within the sleeve and body portions is a jaw blade which terminates at its free end in a pair of opposed clinching jaws resiliently spaced apart.  The jaw blade is slidably mounted in the housing and coacts with a portion of the housing structure for closing the clinching jaws together, the movement of the jaw blade defining a first plane. Positioned within the housing for arcuate movement are a pair of handles, the movement of the handles defining a second plane.  A pair of links provides a force-transferring connection between the handles and the jaw blade.  Each handle defines a force-imparting cylindrical surface the axis of which which is sub-stantially perpendicular to the plane defined by the movement of the handles.  Each of the links contains a cylindrical peripheral edge portion that defines a force-receiving surface, the axis of which is sub-stantially perpendicular to the plane defined by the movement of the jaw blade.  In operation, when the handles are moved toward each other, the force-imparting surface bears against the force-receiving surface to facilitate movement of the jaw blade in order to accomplish a clinching of the clip disposed between the jaws.     A clip cartridge is slidably affixed to the sleeve portion of the clip applier.  The clip car-tridge is movable towards and away from the clinching jaws of the clip applier so that a number of surgical clips can quickly and successively be supplied to the clinching jaws.

Abstract: ABSTRACT    An alarm system for transmitting alarm information via telephone lines has a plurality of alarm transmitters which are located at subscribers' premises and are adapted to transmit signals indicative of the state of alarms associated with the transmitters along telephone lines to associated receivers.  The receivers are located at one or more local exchanges and the receivers at a local exchange are all connected to a local processor.  The or each local processor is connected to a central processor which can direct alarm information to one of a number of terminal stations.  The local processors continuously scan the outputs of the receivers.  When a local processor detects a signal indicative of an alarm condition it transmits a signal coded with the subscriber identity and destination for the alarm information to the central processor which routes the alarm message to the appropriate terminal station. Each transmitter produces a carrier wave which is modulated with one or more other frequencies according to the state of the alarm being monitored.  The local processor claimed herein has means for continuously scanning the outputs of receivers connected thereto, memory means for storing data indicative of alarm conditions sensed during the previous scanning sequence, means for comparing the condition of an alarm with its condition during the previous scanning sequence and means responsive to said comparing means detecting a change in the condition of an alarm for transmitting a signal indicative of said alarm and the destination of the signal to a central processor.

Abstract: ABSTRACT OF THE DISCLOSURE         Antimony values are separated from a material con-taining a sulfo-antimony compound of copper, e.g. tetrahedrite ore concentrate, by a process involving establishing, a pool of molten lead, adding a metallic alkali metal, e.g. metallic sodium, to the molten lead in an amount which is sufficient to reduce the combined antimony of the sulfo-antimony compound or compounds of copper of the tetrahedrite to metallic antimony adding the tetrahedrite ore concentrate to the molten lead, and mixing together the alkali metal, molten lead, and  tetra-ore concentrate.  The alkali metal and sulfo-antimony compound of copper are reacted together in the presence of the molten lead for a period which is sufficient to reduce the an-timony of the sulfo-antimony compound of copper to metallic an-timony and to form one or more sulfo-alkali metal compounds of copper, and a matte phase which separates from the molten lead.          The reduced, metallic antimony passes into the molten lead pool, and the sulfo-alka1i metal compound or compounds of copper report in the matte phase on the surface of thc molten   lead pool. The matte phase is separated from the molten lead.          The metallic antimony is then recovered from the lead.  Al-ternatively, if lead- and antimony-containing alloy is desired as a product, the antimony is retained in the lead, and addi-tional antimony and/or lead may or may not be incorporated into the alloy, as desired or required, to obtain the desired alloy composition.  Should the alloy product be a desired product, the starting lead of the molten pool will ordinarily not be a liquated, rough drossed lead bullion, hut instead another lead such as, for example pure lead or antimonial lead.  The process herein is a relatively low temperature pro-cess employing temperatures of the molten lead pool above the melting point of lead but ordinarily not in excess of 650°C. Further, the instant process does not require a smelting fur-nace but is ordinarily carried out in a kettle.
