Title: Metal halide solid acids and supported metal halides as catalysts for the preparation of hydrocarbon resins
Inventor: BABCOCK LAURA M
IPC: C07C2/06
Filed: 1998-01-07
Abstract: Supported metal halides and metal halide solid acids are used as catalysts for the polymerization of a feed stream containing at least one of pure monomer, C5 monomers, and C9 monomers to produce hydrocarbon resins. Freely-associated water may be removed from the solid acid catalyst prior to use. Resins with softening points (Ring and Ball) in the range of about 5 ~C to 170 ~C can be prepared. These catalysts offer advantages over the traditional Friedel-Crafts polymerization catalysts since the acid sites are an integral part of the solid. The solid acid catalysts are relatively nonhazardous, reusable catalysts which eliminate or at least reduce contamination of the resulting resin products with acid residues or by-products.

Title: Document security system having thermo-activated pantograph and validation mark
Inventor: PHILLIPS GEORGE K
IPC: B41M3/14
Filed: 1997-02-12
Abstract: A document protection system is disclosed which employs a thermochromic pantograph and a validation mark. Also disclosed is a method to print thermochromic pantographs onto a substrate. A thermochromic pantograph according to the present invention has a latent image which is rendered visible when sufficient heat is applied to the document to activate the reactive properties of the thermochromic ink. The latent image could form a warning message such as "STOP" or "ALERT"  which would alert recipients that a counterfeit copy has potentially been created. The thermochromic pantograph may also comprise a camouflage background pattern which conceals the printed ink of the latent image. A validation mark preferably has a latent "validation"  image which can be visually identified on an original document, but which cannot be accurately reproduced by conventional copying or scanning means, and thus will not be visible on an unauthorized copy or duplicate. The use of both thermochromic pantograph and validation mark in the present invention provides multiple levels of protection against the unauthorized alteration or counterfeiting of valuable documents. Used in conjuction, these features allow the present invention to provide efficient and effective protection against unauthorized alterations and counterfeits.

Title: Improved fluid displacing blade
Inventor: LEUNG CHI KEUNG
IPC: B63H1/28
Filed: 1998-04-08
Abstract: A propeller (11) having five blades (13) supported from a hub (14) is exemplified. The propeller (11) is shown with the faces (15) of those blades (13) facing the viewer (out of the page), and has apertures (19) extending through each blade (13) from the face (15) to the back of each blade (13), and spread relatively evenly across the extent of each blade. The axial extent of the apertures (19) is substantially aligned with the direction of movement of the blades (13) relative to the axis of the propeller (11). The apertures (19) are normal both to the radial extent of the propeller (11) and the axial extent of the propeller. Each aperture (19) includes a bevelled edge in the form of a countersunk lip (21) extending around the periphery, on the face (15). The flow of fluid through the apertures (19) is believed to interfere with turbulent fluid adjacent to the back of the propeller (11), and so lead to improved efficiency of the propeller.

Title: Explicit rate computation for flow control in computer networks
Inventor: AWEYA JAMES
IPC: H04L12/56
Filed: 1999-12-07
Abstract: Flow control in a network is implemented based on aggregate traffic measurements. For example, in an ATM network only the aggregate background (CBR/VBR) traffic rate and the aggregate ABR traffic rate are used, in contrast with other schemes that require per-connection rate measurements or variables. An explicit rate is calculated at discrete time instances using a simple proportional controller model. Explicit rate computations can be performed entirely by software, and the interval between computations is large enough to keep the processing overhead required of the switch very low. In addition, methods consistent with the present invention achieve max-min fairness and MCR plus equal share in a natural way without any additional computation or information about bottleneck rates.

Title: A compact front-fed dual reflector antenna system for providing adjacent, high gain antenna beams
Inventor: PEEBLES ANN L
IPC: H04B7/10
Filed: 1999-12-29
Abstract: An antenna system comprising a feed array, a subreflector and a main reflector which are oriented to define a front-fed dual reflector antenna geometry. The feed array is comprised of a plurality of separate feeds which are aligned in a predetermined contour. Each feed array is coupled to a feed network which acts to combine the illumination beams of clusters of a preselected number of feeds to produce a plurality of composite illumination beams. Each composite illumination beam is directed to be incident upon a separate predetermined location on the subreflector which directs the composite illumination beams towards the main reflector. Each composite illumination beam is reflected by the main reflector in a preselected direction so that each composite illumination beam forms an antenna beam that impinges a predetermined coverage area on the Earth. Each antenna beam defines a separate coverage cell in the coverage area, wherein the position and orientation of the feeds, the subreflector and the main reflector provides antenna beams over a full Earth field of view coverage area where each antenna beam is approximately symmetrically shaped.
