Patent CA-2138138-A1 (CA)
Title: Supported Catalyst for 1-Olefin(s) (Co)Polymerization
Inventor: CHANG MAIN
IPC: C08F4/639
Filed: 1993-04-08
Abstract: This invention relates to a supported catalyst composition useful in the polymerization of olefins and to a method for its production. The catalyst is formed by first reacting a trialkylaluminum compound with a transition metal metallocence, and subsequently reacting the resulting material with the undehydrated support material to form a solid product containing at least 20 grams of support material per milimole of transition metal. The resulting supported catalyst has a level of activity comparable to that of conventionally made supported catalysts which are achieved at active metal loadings which are reduced from the loadings used in the previously known metallocene-alumoxane catalysts by at least 20 %, and preferably 50 %. The invention particularly relates to the use of undehydrated silica gel containing from 6 to 20 per cent by weight adsorbed water as the catalyst support material.
Patent CA-2141720-A1 (CA)
Inventor: SHUTE BRUCE W
IPC: F16D65/00
Filed: 1995-02-02
Abstract: A brake shoe for engagement with the tread of a railway car wheel having a tread conditioning agent incorporated in the composition friction brake shoe material of the brake shoe block for altering the adhesion between the wheel and rail on which the railway car is guidably supported. The tread conditioning agent is a material that is dissimilar from the composition friction material of the brake shoe block, being chosen in accordance with a lubricating quality or an abrasive quality depending upon whether the brake shoe use is intended to reduce or increase wheel/rail adhesion. In either case, the chosen conditioning material has a wear rate that exceeds that of the composition friction material so that the degree of conditioning is controlled by the wear rate of the composition friction material and the percentage of brake surface of the brake shoe block occupied by the conditioning material.

Title: Ultra-Fine Whole Wheat Flours and Food Products Made Therefrom
Inventor: WOLT MICHAEL J
IPC: A21D13/00
Filed: 1995-02-07
Abstract: An air attrition mill is used to make an ultra-fine whole wheat flour having a granulation profile substantially as fine as conventional patent flour.  In particular, the granulation profile is characterized in at least 98 wt% of the whole wheat flour has a particle size of 150 microns or less.  This ultra-fine whole wheat flour is significantly different from conventional fine whole wheat flour.  Baked products made with this ultra-fine whole wheat flour have substantially improved textural characteristics. In terms of water absorption rate, gas retention properties, and other processing characteristics, ultra-fine whole wheat flours perform significantly better than conventionally milled fine whole wheat flours in many applications.  Examples are described in which this ultra-fine whole wheat flour is used in bread, cake, cookies, pastry, extruded snack foods, pancakes, pasta, biscuits, tortillas, extruded cereals and related product mixes.

Title: Image communicating apparatus
Inventor: SHIBATA KOICHI
IPC: H04N1/411
Filed: 1995-10-06
Abstract: An  image  communicating  apparatus  transmits  hierarchy images.   A transmitter converts a digital image successively into  a  plurality  of  hierarchy  images  respectively  having resolutions which differ stepwisely.  Data necessary to succes-sively form higher hierarchy images from the lowest resolution image and data of the lowest resolution are outputted.  At least one low hierarchy image among outputs of a transmission informa-tion  former  is  enciphered.    The  transmission  information including the enciphered image is transmitted to a predetermined transmission line in the order of from the lowest to the highest or from the highest to the lowest resolution images.  A receiver reproduces the hierarchy images from image information obtained by deciphering a cipher and the transmission information.

Title: Optical communication system for cable-television signals and for subscriber-assigned signals
Inventor: HEIDEMANN ROLF
IPC: H04B10/60
Filed: 1995-10-30
Abstract: In an optical communication system in which cable-television signals and subscriber-assigned tele-communication signals are transmitted over a passive optical network (4, 5) to at least one optical network termination (6), each optical network termination (6) requires two optical-to-electrical transducers. An optical network termination (6) is disclosed which requires only one optical-to-electrical transducer (24). The system has two transmitting devices (1, 2) which each transmit a respective optical signal (OTV, OD). In the second transmitting device (2), a second electric signal (SD), whose energy occupies a second frequency band is processed in such a way that the energy is concentrated in a subband lying outside the first frequency band (FB1) of a first electric signal (STV). The optical-to-electrical transducer (24) in the optical network termination (6) converts the received optical signals (OTV, OD) to an electric multiplex signal (EMUX), from which the two electric signals (STV, SD) are recovered.

Title: Transverse connection for spinal rods
Inventor: JACKSON ROGER P
IPC: A61B17/56
Filed: 1996-03-15
Abstract: Four versions of clamps originally slidable along two generally parallel spinal rods are swivel connected to three versions of transverse connectors located between the rods. Set screws lock the transverse connectors to the clamps.  Two of the clamp versions use interfitting rotational index locking detents at the swivel connections to fix the final orientation of the transverse connector relative to the spinal rods.  The other two clamp versions use locking tapers to lock the rotational index positions at the swivel connections to fix the final orientation of the transverse connector relative to the spinal rods.  One clamp version uses a separate set screw to fix the clamp on the spinal rod.  One transverse connector has an open clamping head for installation directly onto the spinal rod without sliding it onto the rod from one end or the other.
