Inventor: SHISHKINA ELENA YURIEVNA
IPC: C09B23/00
Filed: 2002-06-03
Abstract: The invention relates to optical devices for producing and/or transforming polarised electromagnetic emission by means of anisotropic absorption and/or optical rotation effects and/or birefringence and can be used as different polarizers (dichroic, reflecting), lagging layers (retarders), liquid-crysta l displays and indicators and also for producing polarising glass for building construction and for sun and antiglare glasses, masks, aprons and faceplates . The inventive optical device is based on at least one molecularly oriented layer of a low-molecular or oligomeric dichroic material which can form a stable lyotropic liquid crystal structure. The projection of at least one anisotropically absorbing fragment of a molecule of the dichroic material on the surface of the molecularly oriented layer of a dipole moment of optical transition is disposed in a parallel position to the optical axis of the molecularly oriented layer at least within several ranges of wavelength of t he electromagnetic emission.

Patent CA-2462941-A1 (CA)
Inventor: BIGCHARLES DONALD
IPC: F01P7/16
Filed: 2004-04-07
Abstract: In the field of cooling of internal combustion engines a known characteristic of thermostatic flow control valves is their lagging control response to variable rates of internal heat generation in the engine. Further, there is a thermal inertia effect due to engine mass and internal fluids masses which masks imbalances between instantaneous internal heating and cooling rates, in many cases allowing internal temperatures to rise excessively and pre-ignition damage or other heat-related component damage to occur to the engine system. The invention seeks to overcome these known characteristics using simple apparatus with a method to effect improved operation of the cooling system.

Abstract: The present invention provides a method and apparatus for resource allocation in a system which includes work items which are to be completed in both business time and real time. Work items are placed in a delta queue which has a calendar associated therewith indicating business time and non-business time for resources associated with the delta queue. When the calendar associated with the delta queue enters into a non-business time, a scheduler pushes an item at the head of the delta queue which corresponds to the amount of non-business time. Work items in the delta queue are thus delayed by the appropriate amount of time corresponding to the non-business time.

Abstract: A VoIP system has a VoIP server and plural clients . The client transmits paging data as multicast packets addressed at a specific multicast address, to other clients. In response to a request from the client, the VoIP server transmits multicast packets of MOH data to the other clients . At this time, whether the other clients can receive multicast packets is determined. To the clients that are determined to be capable of receiving multicast packets, transmission data is sent in the form of multicast packets. To the client which belongs to a router and is determined to be incapable of receiving multicast packets, the transmission data is sent as unicast packets. It is thus possible for the VoIP system to support paging and MOH in the form of multicast packets, with respect to clients incapable of receiving multicast.

Title: Single jaw wedge dead end
Inventor: DE FRANCE ROBERT
IPC: H02G7/05
Filed: 2004-08-19
Abstract: A wedge dead end employs a single wedge-shaped jaw movable in an angled jaw guide between a rearward open position and a forward gripping position. The single jaw wedge dead end defines a fixed cable trough generally parallel to a lower gripping surface of the wedge-shaped jaw. When released from its rearward open position the jaw moves toward its forward gripping position and into a wedging engagement against a conductor disposed in the cable trough. Forward movement of the jaw applies gripping force against the conductor until the full tension of the transmission line is developed.
