Patent WO-9809030-A1 (WO)
Title: Attaches pour colombage
Inventor: CARNE STUART JOHN
IPC: E04B1/61
Filed: 1997-08-29
Abstract: Cette invention porte sur un support d'attache destiné à fixer ensemble des goujons d'extrémité adjacents d'un ou plusieurs poteaux de colombage faisant angle l'un par rapport à l'autre. Le support d'attache est constitué d'un élément profilé en tôle comprenant une partie centrale généralement polygonale (12) délimités par au moins trois marges (14) qui s'entrecroisent à des angles respectifs pour se loger entre les goujons d'extrémité. Plusieurs pattes (20) prolongent respectivement au moins deux des marges pour venir s'engager dans des ouvertures respectives dans les goujons d'extrémité.  Chaque patte est, dans le sens de la projection, plus longue que large, et a grosso modo le même ordre de grandeur par rapport à la longueur de la marge la plus longue. Des formations respectives (28) sont ménagées dans chacune des pattes pour créer des lignes de courbure (29) alternatives espacées, dans le sens de la projection.

IPC: F03B17/04
Filed: 1998-10-15
Abstract: Un poids, de préférence sphérique, attaché par un premier crochet autolibérable à un premier câble d'acier tombe sous l'effet de la gravité dans un premier de deux puits de guidage de transport vertical. Lorsque le poids tombe, il provoque le déroulement du câble d'acier sur l'un des deux éléments d'un tambour tout en provoquant l'enroulement d'un second câble sur l'autre élément. Ledit tambour est relié par une boîte d'engrenage à un générateur à volant cinétique. Lorsque le poids atteint le niveau du sol, l'engrenage est au point neutre, le générateur continue à tourner et le crochet sépare le poids du câble. Le crochet reste suspendu pendant que le poids se déplace vers une chambre d'inversion. Un système à plongeur pousse le poids à travers la chambre d'inversion jusqu'à ce qu'il pénètre dans un puits de retour vertical rempli d'eau, tout en empêchant que les puits de transport ne débordent. Le poids flotte à la surface de l'eau le long du puits de retour. Un second crochet autolibérable attrape le poids sur le second câble d'acier, également enroulé autour du tambour à deux éléments, pour l'amener au premier puits de transport à guidage. Ainsi, le cycle se répète dès lors que le câble s'enroule à nouveau, grâce au crochet, sur le tambour. Ce processus a pour effet de générer de l'électricité en continu.

Title: Metaloxide layer for sensor element for phosphite determination and method for its preparation
Inventor: RACHEVA TODORA M
IPC: G01N27/04
Filed: 1991-12-09
Abstract: The metal-oxide layer is used in the field of semiconductor technology for fabrication of sensor elements for detection of phosphine in various operating media. This layer is highly sensitive to phosphine in the vicinity of its maximum permissible atmospheric concentration, can be used at low temperature, and shows good adhesion to substrates. The metal-oxide layer consists of stannic (IV) oxide, doped with 3.2-5.6 atom percent copper. This layer is obtained by atomisation of a solution of stannic (IV) chloride and copper (II) chloride onto a dielectric substrate previously heated to 450-480 degrees C at a copper (II) chloride to stannic (IV) chloride molar ratio of 1:1 to 1:5. The metal oxide layer thus produced in is then transferred to a pure oxygen environment at 850-950 degrees C followed by cooling to room temperature. The treatment at 850-950 degrees C lasts 30-60 minutes.

Patent WO-03087472-A1 (WO)
Inventor: LALEG MAKHLOUF
IPC: D21H17/29
Filed: 2003-04-07
Abstract: A filler treatment comprising the preparation of swollen starch-latex compositions, prepared in the presence or absence of co-additives, and the addition of the said composition to a filler suspension, has been developed. Use of the treated filler during papermaking improves filler retention and produces filled papers where addition of the filler has only a minimal negative effect on strength properties. The swollen starch-latex compositions can be prepared in a batch or jet cooker, or by mixing (7) with hot water under controlled conditions (i.e., temperature, pH, mixing, mixing time) in order to make the starch granules swell sufficiently to improve their properties as a filler additive but avoiding excess swelling leading to their rupture. The swollen starch-latex composition is then rapidly mixed with the filler slurry (5), preferably in a static mixer (6), and added to the papermaking furnish (1) at a point prior to the headbox (3) of the paper machine. The starch-latex composition can be used with wood-free or wood-containing furnishes. The treated filler is easily retained in the web during papermaking, improves drainage, and gives sheets having good formation. Sheets made with the treated fillers have higher bonding and tensile strengths than sheets produced using filler treated with either swollen starch alone or latex alone.

Title: Broadband switch matrix with non-linear cascading
Inventor: COOPERMAN MICHAEL
IPC: H03K17/00
Filed: 1990-03-09
Abstract: BROADBAND SWITCH MATRIX WITH NON-LINEAR CASCADING    ABSTRACT     A broadband switching matrix having MxN crosspoint switches is arranged into a selected number of groups of vertically cascaded stages in which adjacent groups are interconnected with expansion stages.  An input signal switched from row to column in a particular group propagates through the remaining stages in that group and then propagates successively through the expansion stages in each following group before reaching an output port. In another array configuration, a set of N multiplexers arranged in parallel each receive N input signals and provide a single output signal at a respective output port.  The multiplexers are constructed from 2:1 selector elements which are arranged in a vertical tree configura-tion having log2N cascaded stages.  Each multiplexer has the same number of stages and hence selector elements. Both broadband switching arrays are designed so that each switch drives only one other switch in the array, thereby minimizing capacitive loading and maximizing propagation speed.

Title: Catheter with backflow restriction
Inventor: EGOLF WILLIAM
IPC: A61M25/00
Filed: 1990-05-15
Abstract: An over-the-needle catheter assembly is provided in which a restriction of the inner diameter of the catheter tube is formed in the proximity of the needle hub. The restriction is formed by heating a portion of the catheter tube to the softening point of the catheter material, stretching the catheter tube to cause the heated portion of the catheter tube to tighten about an inner needle or mandril, then releasing the stretching force to allow the stretched portion to relax, leaving a small gap between the inner wall of the catheter tube and the outer diameter of the insertion needle. The small gap is preferably sized to be on the order of the size of the diameter of blood cells to restrict the flow of liquids past the restriction and into the catheter hub.

Title: Method and system for mechanical drying of raw peat
Inventor: LA PRAIRIE LEON
IPC: C10F5/06
Filed: 1990-06-04
Abstract: ABSTRACT     This invention relates to methods for the mechanical drying of raw peat.  Peat, in its naturally occurring state, contains about 90 per cent water, by weight.  Thermal drying of raw peat is inefficient and several methods are being developed to facilitate mechanical dewatering of peat.          It is well known that the natural fibres of peat are quickly destroyed by mining, conveying or by slurry pumping, and thereafter raw peat can be dewatered mechanically only to a maximum of 30 - 35 % solids, by weight, using existing technology.           In order to increase the efficiency of any mechanical devices, recoverable synthetic fibres have been added to the raw peat.     As a result,  raw peat  can be dewatered mechanically up to 45 per cent by commercially available pressure devices.   From 45 per cent, raw peat can be thermally dried up to 90 per cent, and can be used as a high grade fuel with a thermal value of 8,000 to 10,000 Btu/lb.
