Patent EP-0144190-A2 (EP)
Inventor: SHAW HERBERT JOHN
IPC: G02B6/26
Filed: 1984-11-20
Abstract: A fiber optic frequency shifter includes an optical fiber (24) having two modes of propagation, each with a different propagation velocity, and a coupler for applying time varying stress to the fiber at first and second locations on the fiber, with a predetermined phase relationship between the stress at the two locations. The coupler may include a plurality of discrete coupling elements, such as ridges (84, 86) or driving electrodes (163, 164, 165, 166) and a driver to drive the coupling elements in accordance with driving signals having the predetermined phase difference, or the coupler may include an acoustic wave generator (118, 120, 122) coupled to the fiber (114) for applying to the fiber an actual travelling acoustic wave. With the discrete distributed coupling elements, the frequency of the driving signals and the phase relationship between the driving signals is such as to create a simulated travelling acoustic wave in the fiber (24). The real or apparent travelling acoustic wave in the fiber causes light propagating through the fiber to be coupled from one of the fiber modes to another of the fiber modes, and to cause the coupled light to be frequency shifted relative to the initial light. The wavelength of the real or apparent acoustic wave is approximately equal to an integer multiple of the fiber beat length to cause constructive coupling of the frequency shifted light.

Abstract: A signature collator and stitcher is disclosed which provides high output, multiple path operation, automatic repair, and multispeed operation. The collator provides a saddle conveyor which moves the saddles perpendicular to the direction of the saddles so that the signature assemblies are carried in a direction perpendicular to the fold for better control. The saddles are positioned close to each other so that a high density system results in which high production rates can be obtained with relatively low conveyor speeds. The signature feed delivers the signatures to the saddles along an inclined path to provide a component of movement in the direction of conveyor movement for high speed operation. The stitcher operates on the fly for high speed operation and utilizes a simple linkage to produce linear stitcher head movement. The discharge mechanism includes eccentrically mounted nip rolls so that the throat of the nip rolls moves in the direction of conveyor movement when the signatures are raised into the nip rolls by a tucker blade.

Abstract: In an apparatus for generating an image of a scene, preferably an image of a heat image, the image is moved line by line across a row of detectors by means of a scanning mirror. The signals thus generated control light-emitting elements via amplifiers. The light-emitting elements are also disposed in a row, and their light is also guided via the scanning mirror. The scanning of the image is done bidirectionally, that is, during the forward pass and return pass of the scanning mirror. For correction of the resultant phase error, which is brought about by a delayed triggering of the light-emitting elements, an optical deflector element is provided which can assume two defined positions. The first position is associated with the forward pass of the scanning mirror and the second position is associated with its return pass and these positions are entirely independent of the location of the scanning lines. The deflector element is preferably in the form of a plane-parallel plate, which is tilted into two angular positions in alternation by means of electromagnets.

The first member (40) is normally urged by a spring (46) to pivot toward the first side guide part (26). As the button (B) is fed through the feed guide (20), a circular head (l2) of the button (B) tends to be caught in the wedge-shaped groove (23). The first member (40) is then pivotally moved away from the first side guide part (26) against the bias of the spring (46) to allow the button (B) smoothly moved without undue frictional resistance.

Abstract: This invention relates to a method for the detection and diagnosis of AIDS (acquired immune deficiency syndrome), ARC (AIDS-related complex) and pre-AIDS conditions in body fluids by the use of a chemically synthesized peptide comprising peptides containing about twenty-one amino acids according to the formula: 
Arg-Ile-Leu-Ala-Val-Glu-Arg-Tyr-Leu-Lys-Asp-Gln-Gln-­Leu-Leu-Gly-Ile-Trp-Gly-Cys-Ser, analogues thereof and segments thereof. The peptide has an amino acid sequence corresponding to a segment of the envelope protein, p41, of HTLV-III and has been found to be highly immunoreactive with antibodies in sera of patients with AIDS, ARC and pre-AIDS conditions. More specifically, the present invention is directed to the use of a chemically synthesized peptide containing therein a segment of about twenty-one amino acids, or their analogues, in a prescribed sequence for the detection of antibodies to the HTLV-III virus in human body fluids of AIDS, ARC or pre-­AIDS patients. The detection method includes an enzyme-­linked immunosorbent assay (ELISA), an immunoradiometric assay (IRMA), and other forms of immunoassay procedures, such as enzyme immuno blotting assay on nitrocellulose paper and hemagglutination assay, using the peptide as the antigen. The preferred detection method is ELISA. 
     The present invention also relates to a vaccine and a method for generating antibodies to HTLV-III in healthy mammals, including humans, by the use of the chemically synthesized 21mer peptide or its analogues.

Abstract: A controllable temperature grid assembly (1) on which food can be cooked or defrosted is provided which includes an array of spaced tubular members (3) interconnected to form a generally planar grid (4) on which food to be cooked or defrosted can be placed for cooking or defrosting, with the hollow interiors of the members (3) also being interconnected to form a circulation flow path (5) for a heat exchange medium. The assembly (1) also includes heat exchange means (6) in fluid flow communication with the heat exchange medium circulation flow path for extracting heat from or supplying heat to the heat exchange medium. A thermostat is provided in the heat exchange medium for controlling the temperature to which the heat exchange medium is heated or cooled being recirculation through the tubular members (3). When food is cooked on the grid heat is extracted from the tubular members (3) by the heat exchange medium flow to cool the members (3) and thereby reduce the tendency of food to stick to the members during cooking, the extracted heat is removed from the heat exchange medium during flow through the heat exchange means (6) and the cooled heat exchange medium recirculated along the heat exchange medium circulation flow path (5) through the tubular members (3). Frozen food is defrosted on the grid (4) by supplying heat to the tubular members (3) by the heat exchange medium flowing through the members (3) to warm the members (3) and thereby defrost the food. The cooled heat exchange medium is warmed during flow through the heat exchange means (6) and the warmed heat exchange medium recirculated along the heat exchange medium circulation flow path (5) through the tubular members (3).
