Abstract: Dans un système anti-vol conventionnel, les articles protégés sont attachés ensemble soit par des câbles au des chaînes. Les principaux inconvénients de tels systèmes son t les suivants: a) L'employé doit déverrouiller (au moyen de clés) le système de câblage, ce  qui prend du temps et empêche l'employé de donner du service ailleurs puisque, les articl es étant déverouillés, la surveillance doit être concentrée sur ceux-ci. b) Le client hésite à demander le déverouillage, il se sent ma à l'aise au c as où l'article désiré ne convient pas à ses attentes. c) Le voleur, bien organisé, n'a qu'à attendre le moment où le commis sera occupé avec un autre client pour tout simplement couper le système de câblage et partir ave c la marchandise. On a souvent vu des voleurs travailler en groupe de deux, un s'évertuant à occuper et distraire le commis, l'autre à effectuer le vol comme tel. Notre système tend à éliminer complètement les systèmes de câblage et chaîne s trop longs à désactiver et trop faciles à contourner.

Title: Process for selective oxidation of primary alcohols
Inventor: BESEMER ARIE CORNELIS
IPC: C07C45/29
Filed: 1999-05-04
Abstract: Primary alcohols, especially in carbohydrates, can be selectively oxidised to aldehydes and carboxylic acids in a low-halogen process by using a peracid in the presence of a catalytic amount of a di-tertiary-alkyl nitroxyl (TEMPO) and a catalytic amount of halide. The halide is preferably bromide and the process can be carried out at nearly neutral to moderately alkaline pH (5-11). The peracid can be produced or regenerated by means of hydrogen peroxide or oxygen. The process is advantageous for producing uronic acids and for introducing aldehyde groups which are suitable for crosslinking and derivatisation.

Inventor: MORCHAIN PATRICE
IPC: H04R7/04
Filed: 1999-07-22
Abstract: For musical instruments or sound reproduction, it is important that the sound definition is as fine as possible. In the field of sound reproduction electroacoustic transducers provided with round diaphragms or electrostatic system tapes are used. There is no system which indicates if the generated sound is appropriate for the human ear. The method is a fractal shape which corresponds to the shape of the human ear. The method consists in a diaphragm which, just like the ear by its shape is a series of resonators with different frequencies. The shape of the diaphragm of said harmonic amplifier is characterised in that it comprises tongues originating from a common surface, like fingers of a hand originating from the palm. Said method is implemented by an apparatus consisting of a membrane digitised by tongues. The membrane is placed on the musical instrument. Another embodiment of the method consists in a membrane mounted on a sound frequency generator forming an electroacoustic transducer. The method and the apparatus can be used for all types of musical instruments and particularly in the whole of the audio and audio-visual field.

Patent CA-2348252-A1 (CA)
Inventor: SCHMED ARTHUR
IPC: A47J31/44
Filed: 2001-05-18
Abstract: Proposed is a coffee machine for brewing coffee powder pre-packed in a cartridge. For perforating the cartridge, the bottom of the brewing chamber is provided with inclined perforator mem-bers which provide the cartridge with elongate slots that have a greater cross section than the cross section of the particular perforator member. A brewing chamber housing receives two chamber portions delimiting the brewing chamber. The upper chamber portion is adapted to vertically support the cartridge and biased by a spring. For closing the chamber, the brewing chamber housing is raised against a closure piston. The closure piston entering the brewing chamber moves the upper chamber portion against the force of the spring downwards towards the lower chamber portion. In the final position of the brewing chamber housing, the front portion of the cartridge is hydraulically sealed with regard to the rear portion of the chamber by means of sealing members. For brewing the coffee powder, the chamber is hydraulically subjected to an overpressure by means of the brewing water in such a way that the brewing water flows through the perforations into the interior of the cartridge. The front of the cartridge is perforated by means of a closure member provided with projections, such that the brewed coffee beverage can escape through the so created openings and flow to a beverage outlet.

Title: Mammalian subtilisin/kexin isozyme ski-1: a proprotein convertase with a unique cleavage specificity
Inventor: LAAKSONEN REIJO
IPC: C12N9/64
Filed: 1999-11-04
Abstract: Using RT-PCR and degenerate oligonucleotides derived from the active site residues of subtilisin-kexin-like serine proteinases, we have identified a highly conserved and phylogenetically ancestral human, rat and mouse type-I  membrane-bound proteinase called subtilisin-kexin-isozyme-1 (SKI-1). Computer data bank searches reveals that human SKI-1 was previously cloned but with no identified function. A SKI-1 processed fragment is secreted in culture media in a soluble form. In vitro studies suggest that SKI-1 is a Ca2+-dependent serine proteinase exhibiting a wide pH optimum for cleavage of proBDNF.  Peptides mimicking SKI-1 cleavages sites are also disclosed. SKI-1 prosegment has an ex vivo inhibitory effect on SKI-1 activity. The prosegment is also processed and secreted in culture media. One of its fragments is found tightly associated with the SKI-1 soluble form. Therapeutic applications for SKI-1 inhibitors are disclosed.
