Patent CA-2237222-A1 (CA)
Title: Method and apparatus for identifying fluorophores
Inventor: GORFINKEL VERA B
IPC: G01N21/64
Filed: 1996-11-20
Abstract: The present invention is a unique method for identifying the presence, and preferably the identity, of a fluorophore by optically stimulating one or more fluorophores with an optical signal which has been modulated in intensity in the time domain. The stimulated fluorophore produces a resulting fluorescence which is demodulated to produce an electrical signal corresponding to the intensity modulation of the fluorescence. Finally, the electrical signal is compared to the modulation of the optical signal to determine whether or not the fluorophore is present. The present method can be used alone or in conjunction with known methods of optically analyzing fluorescence of fluorophores to determine the presence of fluorophores.

Title: Wheel-activated vehicle restraint system
Inventor: DE BEER FRANK
IPC: B65G69/00
Filed: 1996-11-26
Abstract: A wheel-activated vehicle restraint system including a support structure (30) disposed beside the path of the vehicle approaching the dock, and including a guide member (31) extending away from the dock face, and an elevated supporting member (32). A trigger assembly (50) is operatively connected to the guide member, and initially engages the wheel of the vehicle as it rolls toward the dock. A locking arm (70) operatively engages the supporting member to move from a stored position to a chocking position on the wheel as the wheel engages the trigger and moves it toward the dock. A trolley assembly (60) operatively connects the trigger assembly and the locking arm, the trolley assembly and the locking arm being connected at a connection point (71). The trigger assembly is selectively positionable relative to the connection point in response to the dimensions of the wheel, and the locking arm engages a bottom portion of the wheel, and moves along the peripheral surface of the wheel to a chocking position as the wheel continues to push the trigger assembly toward the dock.

Abstract: L'invention concerne un appareil et un procédé pour améliorer la stabilité de la fréquence de vibration d'un signal d'oscillateur produit par un circuit oscillateur. Dans un mode préféré de réalisation de la présente invention, un résonateur à cristal de quartz constitue une branche d'un pont qui génère un signal variant en fonction de la fréquence vibratoire du résonateur. Un démodulateur synchrone réagit au signal de pont pour produire un signal d'erreur. Un circuit de commande reçoit ce signal d'erreur et modifie sa réactance lorsque le résonateur ne vibre plus à sa fréquence de résonance non perturbée, de sorte que la fréquence vibratoire du résonateur relié au circuit de commande est rétablie à sa fréquence de résonance. Un circuit de régulation de niveau automatique est également incorporé en vue de réguler le niveau d'excitation du signal excitant le résonateur.

Abstract: A process for recovering organic solvent material from a hydrophilic liquid derived from paint overspray treatment operations in which the solvent-in-water emulsion initially contains 1-50 weight percent of an organic liquid having a boiling point of at lest 150 ~C, a vapor pressure less than 0.5 Torr at 20 ~C; and water, and the spent hydrophilic liquid additionally contains paint solid material derived from the paint overspray treatment system in which the recovery process includes the steps of (a) removing the spent hydrophilic liquid or a portion thereof from the paint spray booth; (b) feeding the spent hydrophilic liquid into a reaction vessel, the reaction vessel operating at a pressure less than about 100 mm/Hg and at a temperature sufficient to volatilize the organic liquid component of the hydrophilic liquid; and (c) separating a portion of said volatilized organic liquid from the spent hydrophilic liquid after introduction of the spent hydrophilic liquid into the reaction vessel. The organic liquid component is selected from the group which includes secondary alcohol esters, derivatives of secondary alcohol esters, dialkyl diesters of dibasic acids, and n-methyl pyrrolidones.

Inventor: MITCHELL G FORDE
IPC: A63F9/10
Filed: 1998-12-09
Abstract: This invention relates to a jigsaw puzzle that makes several different pictures with the same pieces. To make a simple puzzle according to this invention one first makes a composite cutting pattern comprised of three different scroll saw type patterns (e.g. outline drawings) superimposed one upon the other. Two visually contrasting puzzle boards are then stack cut with this composite cutting pattern. The result is a puzzle wherein the puzzler can select any one of the three patterns as a guide picture and, using all the puzzle pieces, proceed to assemble two puzzle boards, each with the same outline picture but with reversed contrasting tones, the various picture elements such as shapes and spaces and light and dark areas being defined by the visually contrasting puzzle pieces.  The number of pictures that can be included in a puzzle design of this type is theoretically unlimited. One need only increase the number of outline drawings superimposed one upon the other to make the composite cutting pattern. Surprisingly, all the puzzle pieces are employed to complete the puzzle no matter which picture is being constructed.

Abstract: An improved method of nuclear transfer involving the transplantation of donor cell nuclei into enucleated oocytes of a species different from the donor cell is provided. The resultant nuclear transfer units are useful for the production of isogenic embryonic stem cells, in particular human isogenic embryonic or stem cells. These embryonic or stem-like cells are useful for producing desired differentiated cells and for introduction, removal or modification, of desired genes, e.g., at specific sites of the genome of such cells by homologous recombination. These cells, which may contain a heterologous gene, are especially useful in cell transplantation therapies and for in vitro study of cell differentiation.

Abstract: The invention provides a table horse racing game which imparts much of the fun of actual horse racing. A table frame having lateral and end walls is provided as is a table board which can slide back and forth in grooves provided in the lateral walls. A crank is mounted to a crank shaft mounted in the lateral walls and a nut is mounted to the crank shaft below the table board. An angle plate is mounted to the underside of the board, in contact with the nut. A rubber band is connected between the underside of the board and one end of the frame. Playing pieces resembling horses rest on top of the board. As the crank is rotated the corners of the nut act on the angle plate to cause the board to shake back and forth which has the effect of moving the horses along the board. Bumps can be provided on the board to make it more uncertain as to which of the horses will reach the other end of the board first.

Title: Microdose therapy of female sexual dysfunction by no, co, and their donors
Inventor: BANTING JAMES D
IPC: A61K31/5377
Filed: 1998-06-22
Abstract: Methods for treating vascular conditions associated with localized imbalance in vascular tone, which are hypothesized to be largely due to elevated endothelin (ET), are provided. The methods involve administration of nitric oxide (NO), agents which are able to provide NO, such as NO donors, agents which activate guanyl cyclase, such as YC-1, or agents which prolong the actions of endogenous NO  or cyclic guanosine monophosphate (cGMP; a 2nd messenger molecule), such as phosphodiesterase (PDE) inhibitors. According to the invention, such agents are administered in minimal doses or microdoses by any route known in the art, so as to provide dosages which are about one half to about one twentieth (1/2 to 1/20) of those known to induce vasodilation in "normal" circulations. The low doses of these agents effectively alleviate vascular conditions associated with a reduction in NO production or an attenuation of NO effect, by restoring balance in vascular tone while exerting almost no systemic effect in normal vasculature.
