Title: Aromatic alkylation with a catalyst containing an improved zeolite beta
Inventor: GAJEK RICHARD T
IPC: C07C6/12
Filed: 1998-03-02
Abstract: There is disclosed a new form of a zeolite beta catalyst which shows substantially greater stability and greater catalyst lifetime when used in the alkylation and transalkylation of aromatic compounds. The new, surface-modified zeolite beta is characterized by having surface aluminum 2p binding energies as measured by X-ray photoelectron spectroscopy, of a least 74.8 electron volts. This surface-modified zeolite beta is prepared by treating a templated zeolite beta with an acid at a pH between 0 and 2 and a temperature up to 125 °C for a time sufficient to modify the chemical environment of the surface aluminum atom without bringing about dealumination of the zeolite beta.

Title: Process for treating semiconductor fabrication reclaim
Inventor: RYCHEN PHILIPPE
IPC: C02F1/28
Filed: 1996-12-17
Abstract: The hydrophilic organic contaminants and hydrogen peroxide present in semiconductor fabrication reclaims are removed by means of adsorption of a pyrolysate of a macroreticular sulphonated vinyl-aromatic polymer having a carbon content of at least 85% by weight and a carbon/hydrogen atomic ratio of from 1.5:1 to 20:1. In spite of their hydrophobic surface, the pyrolysates have a comparatively high adsorptivity for these contaminants and provide for distinctively higher removal rates than customary activated carbons.

Patent CA-2234540-A1 (CA)
Inventor: HELMRICH RALPH
IPC: B65D83/14
Filed: 1996-10-15
Abstract: For a pressurized container (12) for dispensing a fluent material (20), the cover or lid (30) is domed, but is of sufficiently thin material that it might distort under elevated pressure in the container. To inhibit such distortion, one or both of the side walls of the cover recess, which is toward the periphery of the installed cover, are reinforced against deforming or stretching out of the container. The radially inner wall of the recess (60) engages the radially outer wall of the recess (34) so that outward distortion of the dome of the cover is resisted by the stiffness of both engaged walls of the recess, strengthening the thin material domed cover against deformation under pressure in the container. Specifically, there may be annular ribs (62) or other engageable deformations on walls of the recess that engage and thereby provide interference against the radially outer wall moving up out of the container upon the dome attempting to deform outwardly.

Patent CA-2237243-A1 (CA)
Inventor: COSGRAVE RONALD FRANK
IPC: F04B53/16
Filed: 1998-05-08
Abstract: A method of reducing leakage from a shaft connection for a pump sealed by compressible packing and a pump fitting.      The pump fitting has a tubular housing which is attached where a shaft extends from a pump housing. Compressible packing is positioned within an interior bore at a second end of the tubular housing. A tubular piston is positioned within the interior bore at the second end of the tubular housing overlying the shaft with a first end of the tubular piston engaging the compressible packing. An end cap is secured on the second end of the tubular housing. As the end cap is tightened it exerts a force upon a second end of the tubular piston thereby causing the first end of the tubular piston to exert a compressive force upon the compressive packing.

Title: Telephone extension switch hook state detection system
Inventor: DETERING GREIG R
IPC: H04M1/715
Filed: 1998-11-09
Abstract: A computer integrated telephony system embodied in a PC that includes a telephony interface connected to the local loop that detects whether one or more extension phones are off-hook by using the signal generating and detection capabilities found on a typical telephony interface card. In the preferred embodiment, the telephony interface is based on a programmable DSP that generates and injects onto the local loop a subsonic signal having a known shape and amplitude. If one or more extensions are off-hook, the amplitude of the subsonic signal detected on the line will be significantly attenuated. The amplitude of the detected signal is compared against a threshold value and an indication is made if the detected signal amplitude is below the threshold value.

Title: Multimedia data communication system
Inventor: MURAI TOSHIO
IPC: H04L29/06
Filed: 1999-02-23
Abstract: A sound element database is installed in an analog telephone hub. When hold operation or the like is performed on an analog telephone during voice communication, the analog telephone hub selectively reads out necessary sound element data from the sound element database, and sends the sound element data or the type information of the sound element data to an analog telephone on the held party side through a LAN. In an analog telephone hub on the held part side, an audible sound is generated on the basis of sound element data read out from the sound element database on the basis of the sent sound element data or the sound element data type information. This audible sound is supplied to the analog telephone on the held party side to be output. With this operation, an audible sound indicating the operation state of a communication terminal can be effectively transmitted to the communication terminal of the other party.

Title: Laminated structural wood products and method
Inventor: SING PETER
IPC: E04C3/29
Filed: 1997-10-06
Abstract: Small-diameter logs (10c) are longitudinally bisected and trimmed to form a flattened surface (56a) parallel and opposite the diametric surface (54a) formed by the bisection. All longitudinal surfaces of logs, half-logs and planks not visible in the final product are subjected to an overall pattern of cuts (70) or perforations (76) to relieve uneven wood fiber tension, the two half-logs are adhesively (58) joined at their trimmed flattened surfaces. Then a second longitudinal bisection (62a) is made through the half-log or plankpile assembly, resulting in two asymmetric structural units (64a, 66a), which are piled in a tight stack (78) to discourage warping as subjected to air- or kiln-drying. The dried structural units may be assembled into rectangular beams (80) or a plurality of them aligned parallely into uniform planar arrays (82, 82a, 86, 86a) for use as paneling, siding, fencing, flooring or decking; tongue-and-grooved laminates (104) of structural units provide strong weatherresistant structures.

Patent CA-2273438-A1 (CA)
Inventor: DYKES CHRISTOPHER A
IPC: A61G11/00
Filed: 1999-06-01
Abstract: An infant care apparatus such as an incubator or infant warmer having a mattress for supporting the infant on an infant platform that can, at times, by fully rotated 360 degrees to obtain full access to the infant. In the incubator, a translation platform can be slid into and out of the infant compartment and the mattress tray is pivoted to that translation platform so as to rotate at a pivot point that connects the mattress tray to the translation platform. Accordingly, when all of the doors of the infant incubator are in the closed position, the mattress tray is constrained from rotational movement but that mattress tray can be rotated a full 360 degrees whenever both doors are open or when the translation platform has been moved to a position at least partially exterior of the infant compartment. In all, the apparatus provides easy and convenient access to the infant for carrying out procedures on the infant while it is still supported by the infant care apparatus.

Patent CA-2276950-A1 (CA)
Inventor: LODI UMBERTO
IPC: H01P1/203
Filed: 1999-07-07
Abstract: A coupling network and a method are described for widening the varactor diode tuning band of microstrip dielectric resonators, for instance in microwave oscillators or in filtering arrangements. The present invention substantially provides for modifying the single-line asymmetric structure of a conventional network still utilizing a single varactor diode mounted on the plane of the microstrip circuit. In other words, the transmission line is duplicated thus creating a dipole structure which assures a tighter coupling with the dielectric resonator. Thanks to the duplication of the transmission line and to the fact that the center of the dipole is the location where currents are higher, it is possible to obtain far wider tuning bands as compared with a known and conventional configuration.
