Title: Autoradiography imaging
Inventor: SPARTIOTIS KONSTANTINOS EVANGE
IPC: G01T1/29
Filed: 1997-03-10
Abstract: A method of autoradiography imaging includes steps of: (a) forming a subject having at least first and second markers, each marker providing radiation having a characteristic energy distribution; (b) detecting radiation from the marked subject using a semiconductor radiation detector having an array of cells, each cell recording a charge value dependent on the energy of incident radiation; (c) processing the output from the cells including discriminating charge values within at least two charge value ranges and allocating a display colour value to each pixel cell position in the array dependent upon the recorded charge value; and (d) forming an image for display with individual cell positions having a colour representative of the colour values. The method enables multiple label or multiple marker imaging in autoradiography to be performed by energy discriminating imaging, thus enhancing experimental accuracy and reproducibility.

Title: A polynucleotide herpes virus vaccine
Inventor: ARMSTRONG MARCY E
IPC: A61K48/00
Filed: 1997-09-26
Abstract: Genes encoding herpes simplex virus type 2 (HSV-2) proteins were cloned into eukaryotic expression vectors to express the encoded proteins in mammalian muscle cells in vivo. Animals were immunized by injection of these DNA  constructs, termed polynucleotide vaccines or PNV, into their muscles. In a DNA titration, it was found that a single immunization of 0.5 µg of (one) PNV, gave 90 % seroconversion by ten weeks post immunization. Immune antisera neutralized both HSV-2 and HSV-1 in cell culture. When animals were challenged with HSV-2, significant (p.001) protection from lethal infection was achieved following PNV vaccination. DNA constructs may be full-length, truncated and/or mutated forms and may be delivered along or in combination in order to optimize immunization and protection from HSV infection.

Title: Support rack for pipette tips
Inventor: TAGGART THOMAS
IPC: B01L9/06
Filed: 1998-10-13
Abstract: A support is provided that is useful with a pipette tip holder for pipette tips. The support (14) has a bottom member (16) and a pair of opposed side walls (18a, 18b). The side walls (18a, 18b) are attached to the bottom member (16) and extend therefrom at least a distance (d). The bottom member (16) and side walls (18a, 18b) form a cavity (20) therebetween. Each side wall (18a, 18b) defines a slot (22a, 22b) therein. The slots are in a facing relationship and extend between first ends (24a, 24b) and second ends (26a, 26b) along a support plane (28). The support plane (28) is parallel to the bottom member (16) and spaced the distance (d) above it. The distance (d) is such that when the tip holder (10) containing pipette tips (P) is inserted into the slots (22a, 22b), the tips (P) do not touch the bottom member (16) but continue to rest on the tip holder (10). Thus, the support (14) supports the pipette tips (P) and pipette tip holder (10) during the pipette tip removal process and resists inadvertent dislodging and lifting of tips (P) and holder (10) as the tips are removed.

Abstract: A dual band combiner for combining two frequency bands having a 2:1 relationship, e.g. 900MHz and 1800MHz. The combiner comprises and upper frequency bandpass filter section and an upper frequency bandstop filter. The bandpass filter section comprises two open-end resonations whose lengths are wavelength of the upper frequency band, and the bandstop filter comprises three open-end resonators whose lengths are 1/4 wavelength of the upper frequency band.  Because of the 2:1 frequency relationship pronounced selectivity-enhancing transmission zeros are produced at the lower frequency band, thereby providing a combiner that has high isolation between ports while maintaining low insertion loss.

Title: Illuminable ramp assembly for a pinball game
Inventor: POPADIUK JOHN A
IPC: A63F7/36
Filed: 1999-06-22
Abstract: An illuminable ramp assembly for a pinball game having a playfield supporting a rolling ball thereon comprises an elongated molded plastic housing and a ball ramp extending alongside the housing. The housing encloses a power supply, a gas tube, protective end caps, and cushioning supports. The gas tube is powered by the power supply. To effectively suspend the gas tube within the housing and, at the same time, provide the gas tube with shock resistance, the protective end caps are mounted over opposing ends of the gas tube, and the cushioning supports are intermittently located along the length of the gas tube. The cushioning supports partially encompass the gas tube and are interposed between the gas tube and the housing. The ball ramp includes an entry end and an exit end. A switch capable of detecting the presence of the rolling ball is preferably located near the entry end of the ball ramp. In response to the rolling ball being delivered to the ball ramp via its entry end such that the rolling ball actuates the switch, a game controller causes the power supply to illuminate the gas tube with an illumination pattern.
