Title: Method of controlling release of caffeine in chewing gum and gum produced thereby
Inventor: TYRPIN HENRY T
IPC: A23G4/20
Filed: 1996-11-27
Abstract: A method for producing a chewing gum with a controlled release of caffeine, as well as the chewing gum so produced, is obtained by physically modifying caffeine's properties by coating and drying. Caffeine is coated by encapsulation, partially coated by agglomeration, entrapped by absorption, or treated by multiple steps of encapsulation, agglomeration, and absorption. The coated caffeine is then preferably co-dried and particle sized to produce a release-modified caffeine for use in chewing gum. When incorporated into the chewing gum, these particles are adapted to produce a fast release or a delayed release when the gum is chewed.

Title: An illumination engine for a projection display using a tapered light pipe
Inventor: LI KENNETH K
IPC: F21Y101/00
Filed: 2002-02-04
Abstract: An illumination engine for a projection display using a tapered light pipe(718) including a reflector having first and second focal points. A sour ce of electro-magnetic radiation disposed proximate to the first focal point of the reflector emits rays of radiation that reflect from the reflector toward the second focal point. A tapered light pipe(718) collects and transmits substantially all of the radiation converged at the second focal point(722), adjusting the numerical aperture of the radiation, but curving the surface formed by the images of the radiation. A straight light pipe(724) or a lens collects and transmits substantially all of the radiation transmitted by the tapered light pipe , flattening the surface formed by the images of the radiation. A condenser lens(707) collects and transmits all of the radiation transmitted by the contoured delay element to a polarizing beam splitter(740 ) and a projection system (738).
Patent CA-2439151-A1 (CA)

IPC: E05B15/16
Filed: 2002-02-20
Abstract: L'invention concerne une serrure à barillet comportant une enveloppe (14) et un barillet (10) situé à l'intérieur de l'enveloppe. Une fiche de verrouillage (52), une fiche de détection (54) et un raccord flexible sont montés à l'intérieur du barillet. La fiche de détection déplace le raccord flexible qui déplace à son tour la fiche de verrouillage en position déverrouillée lorsque la bonne clé est introduite dans une rainure (22) de clé, dans le barillet. La clé comprend une encoche (90) accueillant la fiche de verrouillage, de sorte à permettre à cette dernière de se déplacer en position déverrouillée. La clé comprend également une surface de contact (92) qui déplace la fiche de détection, déplaçant ainsi la fiche de verrouillage en position déverrouillée à travers le raccord flexible. Lorsqu'une mauvaise clé, dépourvue de l'encoche accueillant la fiche de verrouillage, est introduite, la flexibilité du raccord permet à la fiche de détection de se déplacer sans déplacer la fiche de verrouillage. Cette serrure à barillet peut également comporter des gorges à levier classiques. L'encoche d'accueil de la clé peut comporter une surface d'alignement (94) qui coopère avec la fiche de verrouillage pour commander la profondeur à laquelle la clé est introduite dans le verrou et permettre à des clés de longueur variable de s'aligner par rapport aux gorges à levier de la serrure à barillet.

Title: Compressor assembly having baffle
Inventor: SKINNER ROBIN G
IPC: F04C15/00
Filed: 2003-09-19
Abstract: A compressor assembly having a housing with a first inlet. A compressor mechanism within the housing has a second inlet leading to a working space wherein gas is compressed. A baffle surface is extends from proximate the first inlet to proximate the second inlet and is impactable by gas entering the housing through the first inlet. The baffle surface directs gas in a flow path from the first inlet toward the second inlet and defines a baffle opening positioned between the first and second inlets. The length of the baffle opening extends substantially transverse to the flow path and is substantially greater than its width. The baffle opening diverts a portion of the gas directed along the flow path through the opening and intercepts fluid, such as lubricating oil, collected on the baffle surface whereby the fluid is separable by passage through the opening from gas entering the second inlet.

Patent CA-2443515-A1 (CA)
Inventor: BECKER CHRISTOPHER
IPC: C12Q1/37
Filed: 2002-04-03
Abstract: Methods and reagents for obtaining simplified mixtures of peptides from a sample containing a number of peptides are disclosed. The simplified sample can be easier to analyze than the original peptide sample yet it is representative of all or nearly all of the proteins present in the mixed protein sample from which the original and more complex peptide sample was derived. The methods entail the use of tagging moieties that include an amino-acid-specific reactive group (R). The tagging moieties "tag" peptides or proteins at specific amino acids (e.g., by reacting with an amino acid to form a covalent bond), ultimately allowing the isolation of peptides that contain those specific amino acids. Other methods entail the used of a reactive moiety (Rp) that comprises a reagent that selectively interacts with selected proteins, either covalently or noncovalently. For example, Rp can be a natural ligand for a receptor that is to be taged or a protein that interacts with a second protein that is to be tagged. It can be an enzymatic substrate or other element of molecular recognition such as an antibody, ATP, GTP, NAD, NADP, NADH, NADPH, ubiquitin, or structural analogs thereof.

Title: Multizone capacitive anti-pinch system
Inventor: MAJEWSKI JAN
IPC: E05F15/00
Filed: 2002-11-04
Abstract: An anti-pinch assembly is used for a closure panel supported bythe motor vehicle. The closure panel is movable between an open position and a closed position. A controller is operably connected to the closure panel for controlling the operation of the closure panel. A position sensor is connected to the controller for indicating the position of the closure panel as the closure panel moves between the open and closed positions. A capacitive sens or is mounted on the frame of the vehicle and connected to the controller for providing an output signal to the controller indicative of the presence of a foreign object in the path of the closure panel. The controller varies the function of the capacitive sensor through a plurality of threshold levels as a function of the position of the closure panel as indicated by the position indicator. In a critical zone of travel, namely, travel of the closure panel nearing the closed position, the capacitive sensor can be utilized in either a contact mode or a non-contact mode or a combination of both.

Title: Disposable weight-reducing suction cup
Inventor: HAGIWARA HIDENORI
IPC: A61H9/00
Filed: 2002-12-05
Abstract: The top (6) of a disposable weight-reducing suction cup (1) adapted to be intimately contacted with a weigh-reduction subject portion (8) is provided with a projection (24) and a thin-walled portion (35) disposed in the region of the inner surface of the cup (1) opposed to the projection (24). The cup (1) is intimately contacted with the weight-reduction subject portion (8), and then it is evacuated for suction by a pressure reducing valve (16) to dissipate the subcutaneous fat in the weight-reduction subject portion (8).  After suction, this projection (24) is bent to destruct the thin-walled portion (35) to form a hole in the top (6), thereby equalizing the pressure in the cup with the outside pressure. This allows easy removal of the cup (1) from the weight-reduction subject portion (8). The absence of a complicated reduced pressure releasing mechanism results in an inexpensive disposable weight-reducing suction cup. Further, the barrel (4) of the weight-reducing suction cup (1) to be intimately contacted with the weight-reduction subject portion (8) is provided with a deformable portion (25) composed of a recess (20) and a thin-walled portion (18). The deformable portion (25) serves as a pressing portion adapted to be easily inwardly deformed and crushed when the interior (42) of the cup (1) is evacuated, and to laterally press the weight-reduction subject portion (8) to effectively dissipate subcutaneous fat.
