Title: Apparatus and process for polymerising olefin in gas phase
Inventor: CHINH JEAN-CLAUDE
IPC: B01J8/18
Filed: 1996-02-22
Abstract: The present invention relates to an apparatus for gas phase polymerisation of olefins(s), essentially comprising a fluidized bed reactor and at least one conduit for drawing off polymer provided with an isolation valve and connecting the vertical side wall of the reactor to a lock hopper, the said conduit leaving thevertical side wall of the reactor while being directed downwards so that each part of the said conduit forms with a horizontal plane an angle A ranging from 35° to 90°. It also relates to a process for continuous gas-phase polymerisation of olefin(s) in a fluidized-bed reactor, comprising drawing off the polymer from the vertical side wall of the reactor into a lock hopper via a draw-off conduit so that all flow of the polymer in the draw-off conduit is produced according to a downward direction forming with a horizontal plane an inclination with an angle A at least equal to the angle of repose .beta. of the polymer and not exceeding 90°. The present invention improves the degree of filling of the lock hopper and reduces the amount of gas drawn off with the polymer.

Patent CA-2177712-A1 (CA)
Inventor: ALLISON ROBERT JOSEPH
IPC: H04Q9/00
Filed: 1995-09-27
Abstract: A remote electricity metering system is known m which a cen-tral station (LC) communicates with meters (U1-U13) over the mains (10-14), with messages to remote meters being relayed by intermedi-ate meters and the route of a message being determined by the cen-tral station. The present system provides alarm signalling whereby the meters can commumicate direct with the central station.  Each meter can generate a respective combination of alarm frequencies, preferably sequentially and inside the frequency band used  for nor-mal messaging, and the local controller monitors the mains for those frequencies. An error detecting and or correcting code can  be used for the alarm frequency combinations.  The central stationpolls the meter or meters sending the alarm.  The meters are  microprocessor-based, with the normal message signals and the  alarm frequencies being synthesized from a sequence of digital values by a D/A con-verter.

Title: Apparatus for measuring the crush recovery of an absorbent article
Inventor: HONER PETER DOUGLAS
IPC: G01N3/00
Filed: 1996-06-03
Abstract: An apparatus is disclosed for measuring the crush recovery of an absorbent article as well as the article itself. The apparatus includes a tester having first and second arms, at least one of which is movable. The apparatus also includes a first frame member attached at one end to the first arm of the tester. The first frame member has a shoulder with a first wand extending outwardly therefrom. The apparatus further includes a second frame member attached at one end to the second arm of the tester. The second frame member has a shoulder with a second wand extending outwardly therefrom. The first and second frame members are interleaved such that the first and second wands are spaced apart to enable an absorbent article to be positioned therebetween. Movement of the first frame member relative to the second frame member causes the absorbent article to be crushed in a sideways direction between the shoulders. As the relative movement of the frame members is reversed, the absorbent article is able to expand outward toward its original transverse dimension. The amount of sideways recovery is measured as the "crush recovery" value. The absorbent article includes a liquid-permeable cover, a liquidimpermeable baffle and an absorbent positioned between the cover and the baffle. The absorbent article has a crush recovery value of at least about 15 mm, a wet load value of at least about 300 grams, a stress value of less than about 100 grams/mm, and a thickness of less than about 5 millimeters.

IPC: G10L15/20
Filed: 1996-06-06
Abstract: The present invention relates to a pattern recognition system (Fig. 1) which uses data fusion to combine data from a plurality of extracted features (60, 61, 62) and a plurality of classifiers (70, 71, 72). Speaker patterns can be accurately verified with the combination of discriminant based and distortion based classifiers. A novel approach using a training set of a "leave one out"  data can be used for training the system with a reduced data set (Figs. 7A, 7B, 7C). Extracted features can be improved with a pole filtered method for reducing channel effects (Fig. 11B) and an affine transformation for improving the correlation between training and testing data (Fig. 14).
