Patent CA-2098067-C (CA)
Title: Method and apparatus for vacuum/pressure thermoforming
Inventor: RUSH JONATHAN E
IPC: B29C51/04
Filed: 1993-06-09
Granted: 1996-10-15
Abstract: An apparatus and method for plug-assisted thermoforming of a cup or other hollow article has a concave well or cone region machined into its top with a series of small holes drilled near the deepest part of the well and connected to a port inside the plug which is connected to a specifically sized manifold system. The manifold has a source for positive (pneumatic) and negative (vacuum) pressure air. During the machine cycle, a vacuum is introduced into the plug, which draws the hot plastic sheet into the plug well to stretch it. The vacuum is replaced by compressed air to transfer the pre-stretched sheet into a mold. In a particularly preferred embodiment, the plug is shaped to provide stretching in both the central well and in peripheral regions concentric with the well. Controlled air pressure in the mold may be used to provide the concentric prestretching.

Title: Lamp and reflector assembly
Inventor: LEVIN ROBERT E
IPC: F21V7/09
Filed: 1991-10-02
Granted: 2001-12-18
Abstract: A lamp assembly includes a reflector having a concave reflecting surface and an axis of rotation, and a light source includ-ing a filament mounted at or near a focal point of the reflecting surface. The filament has a length to diameter ratio of 6:1 or grea-ter. The reflecting surface is formed as a multiplicity of reflecting facets.  The facets on at least 50 % of the reflecting surface have dimensions and curvatures selected to produce a light pattern wherein a ratio of filament width spread to filament length spread produced by the facets is at least 2:1. Preferably, the facets are arranged in axially adjacent rings. The facets rings can be succes-sively offset in a rotational direction so as to reduce circumferential variations in the light pattern.

Granted: 2000-04-18
Abstract: A radio paging receiver to enable a user to readily and quickly access desired display information even when received display information cannot be displayed at one time. The receiver includes an optical coordinate information reader such as an optical mouse. The information reader has light emitting source of two different wavelengths and light receiving lens for detecting the lights of the two different wavelengths. Also, a plate having two different non-reflective patterns is provided.      One of the pattern is non-reflective to one of the two wavelengths, and another pattern is non-reflective to another wavelength. Therefore, when the user puts and moves the receiver on the plate, the receiver can detect a direction and an amount of the moving by detecting reflected light by the plate.      Whereby, the receiver shifts the display position in the total received display information.

Granted: 1999-02-02
Abstract: A first resonant retrace circuit is operable for generating a first voltage signal and a second resonant retrace circuit coupled to the first resonant retrace circuit is operable for generating a second voltage signal summed with the first voltage signal. An auxiliary winding of a flyback transformer in the first resonant retrace circuit generates a first feedback pulse signal representative of the first voltage signal. A regulator senses the summed first and second voltage signals and generates a second feedback pulse signal representative of the summed first and second voltage signals. The second resonant retrace means is responsive to the regulator. A resistive summing junction combines the first and second feedback pulse signals to generate a composite feedback pulse signal. A voltage level is generated indicative of the energy in the composite feedback pulse signal. An overvoltage protection circuit is responsive to the voltage level for disabling operation of at least one of the first and second resonant retrace circuits.

Abstract: A sterile containment welding device for plastic tubes comprises a pair of side by side spaced tube holders. Each of the tube holders includes a clamp base and a clamp lid. A pocket is provided in each clamp base extending completely across the clamp base so that a plastic tube could be inserted into the pocket and clamped in the holder when its clamp lid is moved to a closed position. Pockets of the side by side tube holders are alignable with each other to permit a plastic tube in one of the holders to be welded to the plastic tube in the other of the holders. A tube locating member is movably mounted at the end of each pocket in the space between the holders. The tube locating member has a wall disposed in the space beyond the pocket for positioning its plastic tube in the proper position for the later welding step when its tube is moved into contact with the walls. An inactivating member is mounted to each clamp lid to contact the tube locating member and move it out of contact with its plastic tube upon the closing of the lid so that the tubes are exposed to be heated and welded together.

Title: Method for use of branched nucleic acid probes
Inventor: HOGAN JAMES JOHN
IPC: C07H21/04
Filed: 1993-01-21
Granted: 2007-06-05
Abstract: Nucleic acid hybridization probes having at least one nucleic acid strand which has at least two separate target specific regions (14, 16) that hybridize to a target nucleic acid sequence (15), and at least two distinct arm regions that do not hybri dize with the target nucleic acid but possess complementary regions that are capable of hybridizing with one another (18, 20).

Title: Apparatus for providing a graphical control interface
Inventor: BALK MICHAEL W
IPC: G06F3/0487
Filed: 1995-08-15
Granted: 2000-05-16
Abstract: Techniques for employing a television set and a television set controller as the control interface for devices which themselves do not have display capability and for services provided via the telephone network. The techniques involve control apparatus which is connected to the telephone network and a television set and is responsive to inputs from a hand-held controller for the television set. The control apparatus outputs a screen which contains control selections to the television set and the user employs the controller to make a selection. The control apparatus then performs the control function specified by the selection. One application is a telephone messaging system: integral with the control apparatus is a system which can answer calls and store voice messages, fax messages, character-string messages, and script messages. The control apparatus plays the voice messages on the television set and provide screens to the television set which display the fax and character-string messages. The script messages contain code which the control apparatus executes to produce displays. Services provided by the telephone network are controlled and displayed analogously. The services may also involve other devices connected to the control apparatus. The control apparatus may further be used with supplemental output devices such as printers and supplemental input devices such as fax machines, electronic pads, and keyboards.

Abstract: Peptide constructs comprised of multideterminant T helper peptides from the envelope glycoprotein of HIV previously  identified to induce proliferative  responses in four different haplotypes of mice and IL-2 responses in 52-73 % of HIV positive, flu positive patients (cluster peptides), were co-linearly synthesized with the peptide 18 of the V3 loop of HIV-1 gp 160, corresponding to the principal neutralizing determinant of HIV-IIIB and also shown to contain a dominant CTL epitope.  Cognate help for peptide 18 antibody was elicited following a single immunization in all strains of mice which had previously responded to a T cell epitope encompassed  by the peptides. In two strains of mice, the level of neutralizing antibody achieved was comparable to levels adequate for protection from homologous viral challenge in chimpanzees.  After a single boost, much higher antibody titers for 90 % neutralization in the range of 1:1000 to 1:16,000 were achieved. Spleen cells from mice of three distinct MHC haplotypes sharing the Dd class I MHC molecule but with different class II molecules, immunized with the compound peptides, exhibited enhanced gp160-specific CTL activity.
