Title: Fuel tank filler assembly for engine driven welder
Inventor: TRINKNER MICHAEL J
IPC: F02B63/04
Filed: 1998-04-15
Abstract: An engine driven welder has a fuel tank with a filler tube that extends upwardly from a reservoir in the machine base.      The filler tube upper end and a cap thereon are below the machine top cover. The machine top cover has a cutout into which is installed a grommet that closes the cutout and that fully protects the filler tube upper end and the cap. The grommet has a hole that seals over a top portion of the filler tube such that any spilled fuel does not leak inside the machine. The filler tube has an expansion space that prevents splashback and spillover during fueling. An angled tail pipe directs engine exhaust away from the welding machine in any desired direction.
Patent CA-2398525-A1 (CA)
Inventor: KOIKE MASAYOSHI
IPC: H01L21/20
Filed: 2000-12-21
Abstract: A first group III nitride compound semiconductor layer (31) is etched by using a mask (4) into islands of dot, stripe, or check pattern so as to form steps.  Without removing the mask (4) on the tops of the upper stages of the steps, a second group III compound semiconductor layer (32) that does not epitaxially grow on the mask (4) can be epitaxially grown vertically and horizontally from the sides acting as the nuclei of the growth to fill in the step portions. Any threading dislocation in the group III nitride compound semiconductor layer (31) is suppressed to be propagated into the horizontally epitaxially grown upper portion of the second group III nitride compound semiconductor layer (32), and therefore a region where threading dislocations are few can be formed in the filled step portions.
Patent CA-2399548-A1 (CA)
Inventor: TREMBLAY ANDRE
IPC: A61K38/25
Filed: 2002-08-23
Abstract: Growth hormone releasing peptides (GHRPs), a family of synthetic analogs modelled from Met-enkephalin, have been found to bind a novel class of specific GHRP receptors in the mammalian heart that are distinct from the pituitary GHRP  receptors involved in GH secretion. CD36, a multifunctional B-type scavenger receptor, has been identified as the unique GHRP binding site in the heart. CD36 mediates the uptake of lipoproteins into a number of cell types and was recognized to play a crucial role in scavenging oxidized low density lipoproteins in monocyte/ macrophages leading to foam cell formation, a key step in fatty streaks formation.     The hexapeptide GHRP prototypes hexarelin (His - DMe - Trp - Ala - Trp - D Phe - Lys - NH2) and EP 80317 (Haic-D Me - Trp -D Lys - Trp - D Phe- Lys -NH2), the latter analog being devoid of GH-secreting activity in vivo, have been shown to reduce fatty streak lesions and hypercholesterolemia in apolipoprotein E (Apo E) null mice fed a high fat high cholesterol diet (HFHC). In addition, non-HDL cholesterol was significantly decreased, whereas HDL cholesterol tended to increase. GHRP treatment also inhibited oxLDL-induced monocyte chemotaxis in the peritoneal cavity, which was associated with a reduced expression of the CD36 protein on peritoneal monocytes/macrophages.  GHRPs may represent a novel therapeutic avenue to reduce the severe morbidity associated with the arterial disease atherosclerosis and its complications, such as myocardial infarction and strokes, that occur despite current management strategies.

Patent CA-2401272-A1 (CA)
Title: Differential detection of signals using generalized orthogonal coding designs transmitted from multiple antennas
Inventor: JAFARKHANI HAMID
IPC: H04B7/06
Filed: 2001-04-27
Abstract: A differential detection approach allows communication without knowing the channel parameters, where the transmitter can include a plurality of transmitting antennas in excess of two.  In the transmitter, each block of bits is mapped to a vector that is processed to develop a symbols vector, by employing mutually orthogonal vectors and the symbols vector of the previous block. The symbols vector is applied to a space-time mapping block, and thence to transmitting antennas. At the receiver, the received signals of a block are formed into vector, which is combined with a corresponding vector from the previous block in accordance with the mutually orthogonal vectors. The combined vector is summed with combined vectors of the other receive antennas, and the summed result is applied to a minimum distance decoder module. The decoder module selects a "most likely" vector, and that vector is applied to a mapping that recovers the transmitted bits.

Title: Dynamic bandwidth allocation circuit, dynamic bandwidth allocation method, dynamic bandwidth allocation program and recording medium
Inventor: MIKI NORIKI
IPC: H04B10/272
Filed: 2002-09-06
Abstract: The aim of the present invention is to achieve a low delay and high bandwidth efficiency in an upstream bandwidth and to accurately reflect assured bandwidth in an actual transmitted bandwidth. To achieve this, in the present invention the maximum value and the transmission cycle of a requested bandwidth are set for each service class. The present invention allocates bandwidth to a service path terminating section based on excess allocated bandwidth and requested bandwidth of each service path terminating section. For each service path terminating section the present invention also selects one bandwidth out of a plurality of bandwidths requested by a service path terminating section in such a manner that the sum value of the allocated bandwidths of the plurality of service path terminating sections is within a predetermined range.

Title: Browser based command and control home network
Inventor: HUMPLEMAN RICHARD JAMES
IPC: G06F17/00
Filed: 1998-06-24
Abstract: A method and system for commanding and controlling diverse home devices. A first home device capable of displaying user interface data is connected to a home network. A second home device stores user interface data that defines a user interface for commanding and controlling the second home device, also connected to the home network. The first device receives the user interface data from the second device over the network. The first device then displays the user interface as defined by the data. The user interacts with the user interface displayed on the first device by a control device. User input is accepted from the user responsive to the interaction. Control and command information is sent from the first home device to the second home device in order to control the second device according to the user input. Since the user interface can be displayed from any device, a single control device may control a plurality of different devices without requiring any change in the mode of operation of the control device.

Title: Improved hot runner sealing apparatus and method
Inventor: JENKO EDWARD J
IPC: B29C45/26
Filed: 2001-02-28
Abstract: The present invention relates to an apparatus and method for injecting molten plastic. The apparatus and method includes a novel non-flat sealing interface therein that prevents the premature leakage of molten plastic. A nozzle with a non-flat sealing surface is brought into intimatecontact with a manifold or bushing. Within the manifold, the bushing and the nozzle is a melt channel for communication of molten plastic to the mold. Thermal expansion at the non-flat interface as well as an initial preload creates a concentrated sealing pressure distribution that prevents leakage of the molten plastic from the melt channel. In one embodiment of the present invention, the bushing has a passageway through which a valve-stem is inserted for closing off a gate in the nozzle.

Abstract: Cables, especially submarine cables (10), generally have black outer sheaths  (11). When placed especially in deep water, said cables are difficult to detect on television images taken with submarine television cameras, and in extreme cases cannot be detected at all. The inventive submarine cable (10) comprises an identifying mark on the outer sheath thereof (11), in the form of a longitudinal stripe (13). Said stripe contrasts sharply with the black colour of the outer sheath (11) due to the lighter, especially yellow colour  thereof. The cable is thus easier to detect on television images.
