Patent CA-2360917-A1 (CA)
Inventor: WILSON TONY
IPC: G02B21/06
Filed: 2000-01-17
Abstract: The confocal microscope has two matched light sources: a first light source (1) and a second light source (8). The light sources (1,8) are arranged to illuminate opposite sides of a modulating mask (6). The light either reflecting from or passing through the modulating mask (6) is then used to illuminate an object O supported on a mount (5). The microscope is arranged so that the object O is mounted on the opposite side of the mask (6) to a camera (7) such that light reflected from the object O passes through the modulating mask (6) before being captured by the camera (7). Subtraction of the image produced using the second light source (8) from the image produced using the first light source (1) generates a confocal image that contains substantially less noise than is possible with available confocal microscopy apparatus.

Title: Device and method for keeping food warm
Inventor: FINCK MARK H
IPC: A47F3/04
Filed: 2000-01-25
Abstract: A food warming device having a bin for holding food products. The bin has an air delivery port and an air intake port located at first and second end walls that are disposed at first and second opposite edges of the bottom portion. The regions above the bottom portion and along the third and fourth opposite edges between the first and second walls are substantially open whereby the food products are clearly visible to customers. The bottom portion has a heated surface for receiving food products to be warmed. An air circulating means forms a stream of circulating heated air that moves from the air delivery port over the heated surface to the air intake port. The food products are warmed by heat emanating from the heated surface and by warm air from the stream of circulating heated air. A balancing system maintains the circulating air in balance by diverting a portion of the return air to ambient atmosphere through a bleed exhaust port.

Title: Process for the preparation of 1-(mercaptomethyl)-cyclopropaneacetic acid
Inventor: MARRUGO HERIKA
IPC: C07C319/24
Filed: 2002-02-06
Abstract: A process for the preparation of highly pure 1-(mercaptomethyl)-cyclopropaneacetic acid is described. Treatment of 1-(hydroxymethyl)-cyclopropaneacetonitrile with an acid provides the corresponding imino ester and/or halo-amide, which when reacted with thiourea provide the corresponding amide-isothiuronium salt. Hydrolysis of the amide-isothiuronium salt followed by an in situ oxidation allows the facile isolation and purification of 1-[1-(carboxymethyl)-cyclopropanemethyldisulfanylmethyl]-cyclopropaneacetic acid (also known as 1-(mercaptomethyl)-cyclopropaneacetic acid disulfide). Reduction of the 1-(mercaptomethyl)-cyclopropaneacetic acid disulfide under mild conditions provides the 1-(mercaptomethyl)-cyclopropaneacetic acid with high purity.

Patent CA-2391294-A1 (CA)
Title: Bras de commande equipant un systeme de suspension de vehicule
Inventor: PIONKE RALF
IPC: B60G3/28
Filed: 2000-12-06
Abstract: L'invention concerne un bras de commande à deux éléments jumelés, qu'on utilise comme bielle de suspension dans un système de suspension de véhicule. Chaque élément présente une section transversale sensiblement en W et des plaques d'extrémité circulaires. Les plaques d'extrémité sont jumelées par des douilles comportant un élément compressible. Lors d'une charge normale, l'arrangement de douilles maintient les deux éléments séparés, ce qui permet à chaque élément de se courber ou de fléchir lorsqu'il est soumis à des forces longitudinales. L'application d'une charge transversale provoque un mouvement simultané des deux éléments qui les amène à se juxtaposer. Cette juxtaposition augmente considérablement la force globale du bras de commande et lui permet de résister à des forces transversales intenses sans gondolement.
