Title: Structurally rigid dopamine d3 receptor selective ligands and process for making them
Inventor: GRUNDT PETER
IPC: C07D307/85
Filed: 2003-09-15
Abstract: A family of structurally rigid dopamine D3 receptor selective ligands is described. The family of structurally rigid dopamine D3 receptor selective ligands has the formula wherein A is cis or trans -CH=CH-, -C=C-, or cyclohexyl. B is cis or trans -CH=CH- or absent.R1 represents an optionally substituted phenyl group, wherein said substituents are selected from the group consisting of: hydrogen, halogen, amino, nitro, hydroxyl, alkoxy, alky l, acyl and pyridyl, and said substitution may occur at any of the ortho, meta, or para positions, or R1 represents a heteroaromatic ring. A preferred heteroaromatic ring is indole, quinoxoline, pyridyl, pyrimidyl, or imidazole . R2 and R3 may be independently hydrogen or a halogen, or R2 alone may be C1, C2, or C3 alkoxy, and m is 1 or 2, and n is 0, 1, or 2.
Patent CA-2506359-A1 (CA)
Title: Convection heat trap
Inventor: MURPHY MARK A
IPC: F16K1/18
Filed: 2000-02-29
Abstract: A water heater includes a water-tight tank, a cold water in the tank inlet defining a water flow path and a hot water outlet defining a water flow path. A flapper valve member including a ring section is fixed relative to one of the water inlet and water outlet. A unitary flapper section extends from the ring section and has a permanently biased central rest position extending at least partially across the water flow path of the one of the water inlet and the water outlet. The flapper valve member may be secured within a spud mounted to the tank around the one of the water inlet and water outlet. Alternatively, a bushing is fixed relative to the one of the water inlet and water outlet, through which an associated water flow path flows. The ring section extends around a portion of the bushing to support the flapper valve member with respect to the bushing. The flapper section moves out of the water flow path in response to water flow and moves into the water flow path in the absence of water flow to restrict the flow of convection currents.

Patent CA-2512107-A1 (CA)
Inventor: SNYDER CHRISTOPHER EUGENE
IPC: H03D7/16
Filed: 2004-01-06
Abstract: The present invention relates generally to communications, and more specifically to a method and apparatus of modulating baseband and RF (radio frequency) signals. A modulator topology is disclosed in which an input signal x(t) is up-converted to an output signal y(t), either by mixing it with two mixing signals .phi.1 and .phi.2 ("pseudo-direct conversion" mode), or by mixing it with only one mixing signal .phi.2 ("direct-conversion" mode). In pseudo-direct modulation mode, the .phi.1 and .phi.2 mixing signals emulate a local oscillator signal; the product .phi.1* .phi.2 has significant power at the frequency of a local oscillator signal being emulated, but neither .phi.1 nor .phi.2 have significant power at the frequency of the input signal x(t), the LO signal being emulated, or the output signal .phi.1 .phi.2 x(t).
Patent CA-2513479-A1 (CA)
Title: Articulating surgical stapling instrument incorporating a two-piece e-beam firing mechanism
Inventor: SETSER MICHAEL EARL
IPC: A61B17/072
Filed: 2005-07-26
Abstract: A surgical severing and stapling instrument, suitable for laparoscopic and endoscopic clinical procedures, clamps tissue within an end effector of an elongate channel pivotally opposed by an anvil. An E-beam firing bar moves distally through the clamped end effector to sever tissue and to drive staples on each side of the cut. The E-beam firing bar affirmatively spaces the anvil from the elongate channel to assure properly formed closed staples, especially when an amount of tissue is clamped that is inadequate to space the end effector.  In particular, an upper pin of the firing bar longitudinally moves through an anvil slot and a channel slot is captured between a lower cap and a middle pin of the firing bar to assure a minimum spacing. Forming the E-beam from a thickened distal portion and a thinned proximal strip enhances manufacturability and facilitates use in such articulating surgical instruments.

Title: Needle valve nozzle
Inventor: GUENTHER HERBER
IPC: B29C45/28
Filed: 2004-02-19
Abstract: The invention relates to a needle valve nozzle (10) for an injection mould, comprising a nozzle body (20) that contains at least one melt channel (30), the latter terminating against or in a nozzle mouthpiece (40) and having a fluidic connection to a mould cavity of the injection mould that is formed by at least one mould insert (50). A shut-off needle (60) penetrates the melt channel (30) and the nozzle mouthpiece (40) and can be displaced longitudinally through said parts, moving from an open position into a closed position. At least one infeed cone (46) is provided upstream of a seal seat (D), in order to centre the shut-off needle (60), the lower end of which forms a shut-off part (70). The aim of the invention is to guarantee a constantly precise guidance and sealing of the needle, whilst at the same time preventing an impairment of the temperature distribution in the vicinity of the nozzle tip. To achieve this, the nozzle mouthpiece (40) consists of a material with high thermal conductivity, whilst the or each infeed cone (46) for the shut-off needle (60) is configured in a centring body (80) consisting of wear-resistant material and running concentrically with the longitudinal axis (L) of the needle valve nozzle (10). The centring body is held against and/or in the nozzle mouthpiece (40) in a positive-fit and its end section (84), which forms an outlet opening (44) for the melt, can be engaged with the mould insert (50).

Title: Stabilization of the effects of jitter on a displayed image
Inventor: SAXENA RAGINI
IPC: G09G5/32
Filed: 2005-11-09
Abstract: In an exemplary display system adapted to display an image to an observer using a display where at least one of the display and observer is subjected to physical vibration referred to as jitter, accelerometers are mounted to elements subject to jitter and associated with the observer. A processing system uses acceleration measurements from the accelerometers to calculate an x-axis and y-axis jitter correction factors based on a comparison of the acceleration measurements, and generates a video output in which the visual information is displaced along the x-axis and y-axis based on the x-axis and y-axis jitter correction factors so that an image corresponding to the video output shown on the display appears to the observer as not having jitter.
