Title: Restriction amplification assay
Inventor: GEORGE ALBERT L JR
IPC: C12N15/09
Filed: 1992-11-12
Abstract: The present invention relates to a method, reagent and kit for the the determination of the presence of target nucleotide sequences by restriction amplification. In the process to detect nucleic acid sequences a target molecule containing a specific restriction site is hybridized with a labeled probe containing a sequence homologous to at least 28 bases of the target molecule. The probe is cleaved with a restriction enzyme that releases the probe for detection if the probe hybridizes to the specific target. Thus, the cleaved probe constantly regenerates and is highly detectable if the target sequence is present in the assay.

Title: Liquid fuel overflow prevention system
Inventor: RAUB JAMES B SR
IPC: B63B27/24
Filed: 1992-11-10
Abstract: A centrally controlled system (2) for preventing overflow of fuels during loading operations includes dual processors either of which can take over the functions of the other processor when it fails. The system also includes full self-diagnostics and automatic testing to ensure that the warning lights (22, 24) and audible alarms (27, 26) at the loading compartments and the warning lights (18) and audible alarms (20) at the central location are operative during loading operations. If warning lights at the loading compartments are not visible due to obstructions, a voice synthesizer (30) is used instead of lights (22, 24) at the loading compartments to announce the compartment identifier on the level of alarm reached. Floats (6, 4) in each compartment operate contacts when the level in the compartment reaches a first high level and when the level in the compartment reaches a second overfill level.  In addition, if the level in any compartment reaches an overfill level, the power to the pumping station is automatically cut-off ceasing the loading operation.

Title: Coded playing cards and other standardized documents
Inventor: SOULES JACK A
IPC: A63F1/14
Filed: 1992-11-18
Abstract: An apparently conventional playing card (10) is invisibly coded so that it can only be read face down, by an electro-optic reading means. The card may be of non-laminated conventional card stock which has a substantially white surface conventionally printed with the identification of the suit and value of the card with inks chosen because they are visible but substantially transparent to wavelengths outside the visible range. The face of the card is coded with indicia inklessly marked across its surface with a compound which absorbs wavelengths (outside the visible range) which wavelengths are used by the reading means to read the indicia.  The indicia, invisible to the human eye, correspond to a code (11) which uniquely identifies the card. The card may be laminated from top and base sheets and the code concealed behind the front printed face of the top sheet.

Title: Method and apparatus of mounting a lens
Inventor: KAMAKURA MITSUTOSHI
IPC: G02B7/02
Filed: 1994-05-27
Abstract: The present invention provides a method for mounting a lens on a light emitting diode chip.  The method includes the steps of placing the package on an XY-stage which can move in a horizontal XY-plane.  A driving current is replenished to the device chip.   The device emits light beams from the emanating region out of the main surface.   The emanating region is observed by a camera which can displace in a vertical Z-direction.  The centre of the emanating region is determined by an intensity projection method and a gravity measurement method.   The centre of the emanating region is harmonized with the centre of the camera by moving the XY-stage in the XY-plane.   The XY-stage  is displaced by a predetermined distance in a predetermined direction to a spot just below a dispenser which can move in the Z-direction.  The dispenser is sunk until a bottom tip of the dispenser comes into contact with the device chip.   A dose of ultraviolet hardening resin is supplied to the chip from the dispenser by contacting the dispenser with the chip.   The dispenser is lifted and the XY-stage  is displaced by a predetermined distance in a predetermined direction to a spot just beneath a vacuum collet holding a lens which can move in the Z-direction.  The vacuum collet is lowered until the lens comes into contact with the resin and with the main surface of the light emitting device chip.  The lens is pushed against the chip by the vacuum collet.  The ultraviolet hardening resin is irradiated with ultraviolet rays.  The lens is fixed on the main surface of the chip by stiffening the resin.  The vacuum collet is then lifted from the lens.  This provides a rear surface, emission type light emitting diode which emits light beams produced at a narrow emanating region out of the rear surface of the substrate in which the device chip has a lens mounted on its rear surface.

Title: Low light color imaging system with cooled integrating camera
Inventor: TORRE-BUENO JOSE R
IPC: G01N15/14
Filed: 1993-07-08
Abstract: A low light level color imaging system acquires po-lychromatic images of body cells at low light intensities when markers attached to the cells are illuminated. Particu-larly in PAP smear sceening, specimens may be marked with a variety of fluorescent stains which have different chromatic signatures but which only weekly emit light from very low structural le-vels of the cells. The inven-tion detects the color intensi-ty of each stain in a specimen image, using an integrating color camera to acquire the image. The signal-to-noise ra-tio of the integrating color camera is enhanced by elec-tronic cooling (50, etc.) of its imaging element (28). A single scanned image of a specimen acquired by the camera includes polychromatic information which identifies all of the fluorescent stains which mark the specimen. A multi-chan-nel color image analyzer is configured to recognize each of the fluorescent colors produced from the fluorescent dyes and to pro-vide a pixellated representation of the specimen image which includes all of the fluorescent colors at their image locations.

Title: Braking system for in-line skates
Inventor: OLIVIERI ICARO
IPC: A63C17/14
Filed: 1995-06-12
Abstract: A braking system for an in-line skate, where a linkage assembly connects a rotatable boot cuff to a brake assembly which pivots between a retracted position braking position. The linkage assembly includes a drive arm, a transfer bracket and a short connector link. The transfer bracket has three pivot points which are arranged such that the mechanical advantage provided by the transfer bracket in translating downward movement of the drive arm to downward movement of the connector link and brake assembly is less than one in the retracted position, and increases as the cuff is rotated rearwardly to move the drive arm downwardly and the brake assembly towards the ground. Preferably, the connector link rotates over centre to a locked position once the brake is in contact with the ground and the cuff is rotated slightly rearwardly. The distance between the cuff and the brake assembly is adjustable so that the desired adjustment of the linkage assembly and braking system can be maintained as the brake pad wears down.
