Abstract: An electrical rocker switch having a clam-shell like in which a rocker is pivotally mounted. A unitary multi-function operating assembly fabricated from spring stock materials operates as an over-center spring to establish two rest positions for the rocker. A bifurcated or trifurcated second end of the operating assembly provides springs to urge the contact assembly into intimate engagement with the boss on the underside of the rocker and provide for receiving an electrical conductor. Cross-members of the operating assembly bear movable contacts which selectively engage fixed contacts on the housing to complete external electrical circuits connected to the operating assembly and fixed contacts. An additional housing can be placed about the clam-shell like housing to seal the switch from the environment.

Abstract: An abrasive grit for a metal bonded Single Layer abrasive tool includes abrasivegrains coated with a first active component. The active component is mechanically-bound to the surface of the superabrasive grains. Preferably the abrasive is a superabrasive, especially diamond, and the first active component is titanium, either in the form of elemental Ti or TiH2. The novel grit is made by mixing the first active powder component in a liquid binder to form an adhesive paste; mixing the paste with the abrasive grains to wet the grains, and drying the mixture to adhere active component to the grains. The coated abrasive can be brazed onto a core to form aSingle Layer tool, especially with a brazing composition that includes a bronze alloy and small concentrations of a second active component. During brazing the novel abrasive grains provide excellent surface contact with the brazing composition and the braze strongly bind the grains to the tool core. The brazed composition is easy to chemically or electrochemically strip from the cores of worn abrasive tools to permit reconstruction of the tools.

Abstract: The present invention relates to methods and compositions for eliciting an immune response and the prevention and treatment of primary and metastatic neoplastic diseases and infectious diseases. The methods of the invention comprise administering a composition comprising an effective amount of a complex, in which the complex consists essentially of a heat shock protein (hsp) noncovalently bound to an antigenic molecule. "Antigenic molecule" as used herein refers to the peptides with which the hsps are endogenously associated in vivo as well as exogenous antigens/immunogens (i.e., with which the hsps are not complexed in vivo or antigenic/immunogenic fragments and derivatives thereof. In a preferred embodiment, the complex is autologous to the individual. The effective amounts of the complex are in the range of 100-600 micrograms for complexes comprising hsp70, 50-1000 micrograms for hsp90, and 10-600 micrograms for gp96. The invention also provides a method for measuring tumor rejection in vivo in an individual, preferably a human, comprising measuring the generation by the individual of MHC Class I-restricted CD8+ cytotoxic T lymphocytes specific to the tumor.

Title: Multilayer thin film bandpass filter
Inventor: CUSHING DAVID HENRY
IPC: G02B5/28
Filed: 1998-09-03
Granted: 2003-03-25
Abstract: A novel design for producing band pass filters with essentially square shapes with little or no ripple in the passband zone. Filters are of the all-dielectric type consist of multiple cavities of band passes. Quarter wave thick layers of low index material separate all of the cavities from each other. Multiple half-waves may be added to the outer cavity quarter-wave stacks in particular. This invention provides the addition of half wave to some of the inner cavity stacks to remove ripple that would otherwise be present. Together, these additional half wave layers added to the outer and inner cavities sharpen the transition from low transmission to high transmission without unduly adding ripple to the high transmission zone.

Abstract: Despreading means 10 despreads a pilot signal included in a first received signal 1.  Of the pilot signal despread by the despreading means 10, strength determination means 15 determines the strength of the received pilot signal.          Integration control means 16 determines the integration interval used by integration means 13, from the strength of the received pilot signal determined by the strength determination means 15.  The differences in strength detected by strength difference detection means 12 are added together by the integration means 13 over the period of time decided by the integration control means 16.  The integration time used by the integration means 13 is made changeable according to the receiving environment.  Accordingly, when there is the superior receiving environment, there is reduced the load imposed on the integration means 13 when the integration means 13 performs the processing operations.  Therefore, there can be realized a superior CDMA receiver phase tracking system which dissipates a fewer amount of electric power.

Abstract: An optical fiber flexfoil (1) comprises optical fibers adhesively bonded between two flexible foils (3, 7) laminated to each other. A surface of a base flexible plastic sheet (3) is coated with a pressure sensitive adhesive (5) and optical fibers are bonded to the sheet by the adhesive (5). A top foil (7) having a similar coating (9) is placed on t op of the base foil (3) contacting the optical fibers, air located between the foils is removed and the foils are pressed against each other using a rubber bag formed of two superposed rubber sheets (11, 13) to bond the foils to each other only by means of the adhesive coatings ( 5, 9). The adhesive is selected to have a low glass transition temperature such as below -50 .degree.C and to exhibit visco-elastic characteristics in the temperature range within which the flexfoil is to be used. The lamination of the foils is made at temperatures at the upper limit of the operational range using only moderate pressures. This gives low mechanical stresses on the fibers in the pressing operation. The fibers are not entirely rigidly fixed to the foils allowing them to move a little when bending the flexfoil, so that rather sharp bends of th e flexfoil (1) can be made. Also, microbends formed in the lamination process can relax and thus be eliminated whatproduces a low attenuation in the optical fibers.

Abstract: This invention is directed to apparatus and methods for producing soap bars having a multicolored or marbleized appearance and made from a variety of different colored soap materials. Solid soap in pellet or granular form of one color is introduced into a soap plodder. A second or alternative color of soap pellet is separately introduced into the interior of the plodder just before that point where the helical screw of the plodder enters the barrel of the extruder portion of the plodder. The plodder is structurally modified so that the second or alternate color is introduced into the plodder by means of a special pellet feeding apparatus which not only controls the rate of delivery of the alternate soap color soap pellet but insures that such pellets are introduced into a chamber formed by a flight of the helical screw immediately before the point where the screw enters the plodder barrel.
