Title: Process and apparatus for the polymerization of propylene
Inventor: PATER JOACHIM
IPC: B01J8/18
Filed: 2005-12-09
Abstract: A process for preparing heterophasic propylene copolymers by polymerizing propylene in the presence of a polymerization catalyst and hydrogen as a molecular weight regulator, the process comprising the following steps: a) polymerizing in gas- or liquid-phase propylene to prepare a crystalline polymer fraction; b) copolymerizing ethylene with propylene and/or 1-butene, and optionally one or more alpha-olefin comonomers C5-C12, in a gas-phase reactor having interconnected polymerization zones, wherein the growing polymer particles flow upward through a first polymerization zone (riser) under fast fluidization or transport conditions, leave said riser and enter a second polymerization zone (downcomer) through which they flow downward under the action of gravity.
Patent CA-2592650-A1 (CA)
Inventor: LANGE FREDERICK M
IPC: H04N5/232
Filed: 2007-06-21
Abstract: A system whose most common use is that of inspecting conduits such as sewers, drainage pipes, water, gas and oil conduits. Contrary to camera systems currently on the market, the system has individual components that are easily disconnected and reconnected so that a failed component can be determined and replaced in the field, yet it maintains its integrity against damage from the type of effluent in which it is required to operate. The system's control unit is easily disconnected and replaced, and is mounted on a carrier. The system includes a push rod assembly that has male or female plugs providing quick disconnects at each end so that it can readily be disconnected from opposite gender plugs on a rotary contact assembly at one end and a video camera assembly at its other end. The rotary contact assembly is mounted on the carrier and is similarly connected to and from the control unit, which is physically separate and is also mounted on the carrier. The carrier also has a reel on which the push rod assembly is stored.. Electrical power is provided from a power source for the camera and the video equipment that receives video signals from the camera. The power source may or may not be mounted upon the carrier. The novel splices between the wires of various units and either a male or a female plug by which units are connected are a major contribution to the success of the invention. Similar splices can also be used for field repairs to damaged push rod assemblies or for increasing the overall length of the push rod assembly.

Title: Identification, verification, and recognition method and system
Inventor: HOFFMANN ANDRE
IPC: G06K9/00
Filed: 2005-03-22
Abstract: The invention relates to the field of identification and verification of living beings with the aid of the form, shape, contour, silhouette, surface structure, color, and characteristics especially of sets of teeth, individual teeth, tooth parts, and the relation thereof to the facial and body structures surrounding the same. Systems that are suitable for recording said person-related characteristics are based on detection by means of laser, a camera, sensor, image, color, etc., for example. Disclosed are a series of possibilities and constructions on how a "dental fingerprint" can be detected so as to generate data. The invention does away with problems inherent to previous systems in this field as a result of the great advantage created by the independence of the teeth from facial expressions. The detection of the surface is to indicate whether a being is alive or dead. The inventive method and system can be used wherever the identity of a person has to be proven in order to grant access or control, for example. Potential users include the bank sector, computer security, e-commerce, public authorities, enterprises, the health sector, telecommunication, and private entities.

Abstract: A system and method for collaborating with a billing system is provided for use in a converged telecommunication network that includes a cellular telephone network and an IP-based network. During an IP-based call registration process, a mobile device communicates with a network controller over the IP-based network. The network controller accesses a database with the information provided by the mobile device and subsequently overloads values for an existing field in a call detail record (CDR). Upon completion of the call over the IP-based network, the network controller communicates the overloaded version of the CDR to an MSC which generates the final CDR that is used for billing. Any appropriate field of the CDR can be selected for overloading, such as for example an existing CGI record field from the CDR.

Title: A bin tunnel with collapsible sides
Inventor: YAMAMOTO DAVID K
IPC: B65G67/04
Filed: 2008-02-20
Abstract: A bin tunnel having collapsible sides is used with a truck box of a truck to load content into the truck box from a bin that is sized to fit within the bin tunnel when the bin tunnel is in an open position. When the bin tunnel is in a closed position a footprint of the bin tunnel is very small compared to the open position because the sides are retracted. The footprints can be less when the bin tunnel is in the closed position from thirty (30) percent of the footprint of the bin tunnel in the open position. When the bin tunnel is closed, the contents of the truck box are secure as the space inside of the closed bin tunnel is too small to allow access to the interior.
