Title: Bandelette de test
Inventor: STEWART ALAN ANDREW
IPC: G01N27/327
Filed: 1999-05-06
Abstract: On a mis au point une bandelette de test jetable améliorée destinée à être utilisée pour effectuer la mesure ampérométrique d'analytes présents dans un milieu liquide complexe, tel que du sang, qui comporte au moins trois électrodes. La bandelette est conçue de sorte que différents potentiels électriques puissent être maintenus entre une première pseudo-électrode commune faisant office de référence et de compteur et chacune des deuxièmes électrodes lors de l'application d'un potentiel commun par un ampéromètre. Cette propriété est conférée à la bandelette de test par l'ajout de différentes résistances de circuit associées aux deuxièmes électrodes. La bandelette de test peut être utilisée pour mesurer un seul analyte tel que du glucose avec une compensation du fond effectuée par une électrode "d'épuration" ou pour mesurer la concentration de plusieurs analytes.

Title: Process for making aromatic aldehydes
Inventor: SALEH RAMZI YANNI
IPC: C07C63/16
Filed: 1999-09-10
Abstract: Alkyl aromatic compounds are converted to alkyl aromatic aldehydes by a carbonylation reaction. The carbonylation catalyst can be a high boiling poi nt carbonylation catalyst which allows for the separation of the aldehyde produ ct by selective volatilization. Alternatively, the carbonylation catalyst can b e selected from perfluoroalkyl sulfonic acids having 2 to 18 carbon atoms, perfluoroether sulfonic acids having 2 to 18 carbon atoms, BF3.(ROH)x wherei n R represents CH3 or H and X is a number within the range of from 0.2 to 2, GaBr3, GaCl3, TaF5, NbF5, and NbBr5, with the proviso that when the catalyst  is TaF5, NbF5, or NbBr5, then the reaction takes place in the absence of add ed HF. Preferably, all of the carbonylation reactions take place in the absence  of added HF. The alkyl aromatic aldehydes can be oxidized to form an aromati c acid. A mixed xylene feed stock can be converted to a mixture of diemthylbenzaldehydes and then oxidized to form trimellitic acid without the  need to separate the xylene or dimethylbenzaldehyde isomers.

Abstract: An improved multi-layer gasket for an internal combustion engine comprises an inner spacer layer sandwiched between top and bottom surface layers. The inner spacer layer provides cylinder openings designed to correspond with each cylinder bore in the engine block. Channels cut in the spacer layer extend outwardly from each cylinder opening. A combustion-sealing member formed with tabs extending outwardly from the circumference of the sealing member is received into each cylinder opening and orientated with each tab residing in a channel. Each tab is embossed at its distal end and eyeletted with an eyelet to the top and bottom layers. Tabs retain the sealing member in the cylinder opening, positively locate the sealing member over the cylinder bores on the engine block during installation and permit the sealing member to float in the cylinder bore during operation of the engine independently of the spacer layer.
