Patent CA-2383314-A1 (CA)
Inventor: POLEGA DENNIS M
IPC: G01N3/24
Filed: 2002-04-25
Abstract: The present invention provides an apparatus for measuring the shear strength of rubber bonded to a metal insert in a valve seal, said apparatus comprises an upper fixture and a lower fixture. A mounting device is disposed in the lower fixture of the apparatus for retaining the valve seal. A shearing means is disposed in the upper fixture of the apparatus for shearing the rubber bonded to the metal insert. The shearing means has an arcuate edge for contacting the valve seal. There is a first means engageable with the shearing means for controlling its movement in one of a downward motion for shearing the valve seal and an upward motion for returning the shearing means to its starting position. Further there is a second means for recording the movement of the shearing means and the force that is applied by such first means until a bond between the rubber and the metal insert of the valve seal is broken.

IPC: G02B27/18
Filed: 2000-08-11
Abstract: The invention concerns an illumination device, particularly for wavelength dependent light outcoupling with at least one, preferably wavelength dependent, mirrored surface (7) within the lamp's beam (1) to separate the beam into a component used for illumination and an unused spectral component. The purpose of the invention is to provide an illumination device and a method to optimise illumination quality using simple means. The basic purpose of the invention is solved by placing a mirror (16) in the beam of the unused spectral component which reflects it in the direction of a mirrored surface and a portion of which is projected on to a viewing screen (19) for adjustment.

Title: Spectrometre concentrique attenuant les reflexions speculaires internes
Inventor: PALUMBO PERRY A
IPC: G01J3/02
Filed: 2000-11-13
Abstract: Les spectromètres concentriques sont envahis par des réflexions internes dues à la nature inhérente de plusieurs surfaces optiques possédant un centre de courbure commun. Les réflexions générées par les surfaces optiques se produisent lorsque les indices de réfraction des supports dans lesquels un faisceau ou rayon optique d'une longueur d'onde donnée se propage sont différents ou changent. Les réflexions internes dans les systèmes optiques concentriques peuvent produire une myriade de phénomènes optiques indésirables au niveau du plan de l'image, à savoir entre autres, de multiples images d'un objet, les franges d'interférence et la lumière parasite. Ce phénomène, où la lumière ou le rayonnement détectable qui arrive sur le plan de l'image ne vient pas s'ajouter à la formation de l'image voulue (lumière parasite) donne lieu, par conséquent, à une perte de la ligne de contraste ou de détection. La présente invention produit des images de haute qualité exemptes de ce(s) phénomène(s) optiques dus aux réflexions internes du fait qu'elle empêche la propagation du rayonnement réfléchi dans tout le système optique.

Abstract: A simple block coding arrangement is created with symbols transmitted over a plurality of transmit channels, in connection with coding that comprises only simple arithmetic operations, such as negation and conjugation. The diversity created by the transmitter utilizes space diversity and either time or frequency diversity. Space diversity is effected by redundantly transmitting over a plurality of antennas, time diversity is effected by redundantly transmitting at different times, and frequency diversity is effected by redundantly transmitting at different frequencies. Illustratively, using two transmit antennas and a single receive antenna, one of the disclosed embodiments provides the same diversity gain as the maximal-ratio receiver combining (MRRC) scheme with one transmit antenna and two receive antennas. The principles of this invention are applicable to arrangements with more than two antennas, and an illustrative embodiment is disclosed using the same space block code with two transmit and two receive antennas.

Title: Quick-release fitting assembly
Inventor: ELLIS GEORGE S
IPC: F16L37/088
Filed: 2003-02-13
Abstract: A quick-release fitting assembly has a male fitting and a female fitting. The male and female fittings are secured together by a retaining ring that is at least partially received in aligned first and second retaining grooves that are provided in the male fitting and the throat of the female fitting respectively. A water tight seal is provided by an O-ring that is retained in a sealing groove of the male fitting and radially compressed against the throat wall when the male fitting is inserted in the female fitting. The water tight seal remains substantially intact when the male fitting is rotated relative to the female fitting. In a preferred embodiment, the male fitting is removable from the female fitting by first compressing the retaining ring so that it no longer extends into the second retaining groove.  In this embodiment, a locking ledge may be provided in the first retaining groove which prevents the retaining ring from being compressed when the fitting is under pressure so that the male fitting cannot be removed from the female fitting under pressure.
