Granted: 2001-07-24
Abstract: The invention relates to a vehicle track for tracked vehicles intended for use in all types of terrain, both hilly terrain and in wetlands and on different types of ground surfaces, such as asphalt, concrete, gravel, sand, stone, snow and ice. The track (10) includes one or more endless traction elements (12) made of an elastomeric material,  and cross-ribs  (11) which are spaced apart generally equidistantly and extend transversely and outwardly from the traction element  (12). The cross-ribs are intended for contact with the ground when moving the vehicle, wherewith at least those parts of the cross-ribs (11) which come into contact with the ground are comprised of a polymeric material (27) which is firmly held and supported by a flexurally rigid support device (26). The vehicle track is characterized in that the support device (26) is comprised of a fully closed profile construction, and in that the polymeric material (27) is applied to the outside of said profile construction. The profile construction (26) is conveniently produced from a material chosen  from the group: high-quality steel, aluminium, magnesium or composite material,  although preferably  from a boron-alloyed, high-strength steel. The polymeric material (27) in the cross-ribs (11)  is  suitably pressed-moulded  around  the  fully closed profile construction (26).

Title: Gas turbine cooling moving blade
Inventor: TOMITA YASUOKI
IPC: F02C7/18
Filed: 1998-03-24
Granted: 2002-12-10
Abstract: The present invention relates to a gas turbine cooling moving blade and is applied to a large-sized blade for a high temperature so as to reduce its thickness and increase cooling efficiency and easily process the moving blade.  A cavity is formed in the interior of the moving blade from the root portion to a shroud at the tip of the moving blade.          Many turbulators are arranged in parallel with each other on an inner wall face of the moving blade.  Cooling air from a turbine rotor enters the cavity formed within the moving blade from a cooling air inlet.  This cooling air is dispersed and disturbed by the turbulators so that heat transfer is improved.  Accordingly, the moving blade is efficiently cooled by the cooling air in comparison with a conventional cooling system having a multiplicity of holes.          The cooling air is then discharged out of a cooling air outlet through air cooling holes of the shroud located at the tip of the moving blade.  Accordingly, the proportion of the hollow space within the moving blade is increased by the cavity and the moving blade is made light in weight.  The moving blade is more easily processed and the cooling efficiency of the moving blade is increased.

Granted: 2003-06-10
Abstract: A lock mechanism for a fenestration assembly, such as a sliding door, includes a strike element preferably coupled with the door frame and a catch assembly preferably coupled with the fenestration member slidably supported within the frame.  The catch assembly includes a catch having structure defining an element receiving slot.  The catch is mounted for shifting among a plurality of positions including an engaged position in which the element is received within the slot and retained therein by the catch when the fenestration member is in a closed position, a disengaged position in which the element is disengaged by the catch when the fenestration member is shifted out of the closed position, and an intermediate position in which the element is received within the slot and the catch is positioned between the engaged and disengaged positions.  The catch assembly further includes locking structure for shifting the catch from the intermediate position to the engaged position, and thereby shifting the fenestration member to the closed position, and for locking the catch in the engaged position.  The lock mechanism may also be provided with structure for blocking movement of the strike element out of the element receiving slot defined in the catch, when the catch is in the engaged position so as to reduce the risk of intrusion through the fenestration assembly.

Granted: 2005-01-25
Abstract: A development test system and method for testing Open Systems Interconnection (OSI) layers 3 through 7 of a communications protocol utilized between nodes in a telecommunications network. The system comprises a protocol simulator (73) that simulates OSI layers 3 through 7 of the communications protocol, a local area network (LAN) (79) connected to the protocol simulator with a first Internet socket interface (78) which replaces OSI layers 1 and 2 of the simulated communications protocol, and a target telecommunication node (71) connected to the LAN with a second Internet socket interface (81) and performing operations with blocks of application software to validate the use of the communications protocol with the target telecommunication node (71). A protocol interface gateway (PIG-tool) (84) is connected to the LAN with a third Internet socket interface (83), and serves as a gateway to a target telecommunication system emulator (72). The target telecommunication system emulator emulates a target telecommunication node and performs operations by executing the code of the application software utilized in the target telecommunication node. The operations validate the use of the communications protocol with the target telecommunication node software without having to utilize the target node hardware.

Patent CA-2256224-C (CA)
Inventor: RUSSEK STEVEN LEE
IPC: C01B13/02
Filed: 1998-12-16
Granted: 2002-05-28
Abstract: Hydrocarbon feedstocks are converted into synthesis gas in a two-stage process comprising an initial steam reforming step followed by final conversion to synthesis gas in a mixed conducting membrane reactor. The steam reforming step converts a portion of the methane into synthesis gas and converts essentially all of the hydrocarbons heavier than methane into methane, hydrogen, and carbon oxides. The steam reforming step produces an intermediate feed stream containing methane, hydrogen, carbon oxides, and steam which can be processed without operating problems in a mixed conducting membrane reactor. The steam reforming and mixed conducting membrane reactors can be heat-integrated for maximum operating efficiency and produce synthesis gas with compositions suitable for a variety of final products.

Title: Shell for sports shoes
Inventor: MARCOLIN ALESSANDRO
IPC: A43B5/04
Filed: 1999-01-13
Granted: 2007-10-30
Abstract: A shell for sports shoes, particularly for Telemark skiing, which comprises a sole and a lateral surface which surrounds the foot of the user. A frame is rigidly coupled internally to the shell and has a foot resting surface and a toe cup which partially extends over the upper metatarsal region. On the resting surface and on the toe cup there are, respectively, at least one first transverse opening, arranged below the metatarsal region, and at least one second transverse opening, which lies above the metatarsal region. A transverse bridge, arranged in the region that lies to the rear of the metatarsus, is thus formed at the toe cup. The resulting shell is therefore highly flexible but torsionally rigid, making it easier for the user to ski.

Abstract: Variances in bandwidth used by a radiocommunication connection are adapted to by changing the type of information being transmitted. For example, in a TDMA environment, a first downlink time slot associated with a double- or triple-rate connection may have a first format, while a second time slot associated with the same connection may have a second format different from the first format. Additional bits in the second (or third) time slot can be used to carry payload information which is not required to be transmitted at greater than full-rate. Moreover, FACCH information need only be transmitted in the master channel.

Title: Method for preparing alkaline solutions containing aromatic polymers
Inventor: DOPPENBERG FRANK
IPC: C09K23/50
Filed: 1998-03-20
Granted: 2005-11-01
Abstract: The invention proposes a process which enables separation of aromatic polymers which can be precipitated by acidification, as can be found especially in waste water from cellulose production, from an alkaline solution in a reliable manner and in pure form. To achieve good separation capacity, especially by filtration, it is proposed that the polymers be precipitated by reducing the pH at a relatively low temperature, typically between 15 and 60.degree.C, and the dispersion be subsequently reheated until it passes into filterable form, typically between 50 and 95.degree.C. The product separated in this way for example by filtration can be washed and can be dried at a high temperature, especially up to 110.degree.C, without becoming black.
