Title: Oil filtration apparatus
Inventor: MERCHANT GERALD
IPC: B01D35/147
Filed: 1998-07-10
Abstract: An oil filtration apparatus includes external vanes with associated flow passages. Oil entering a housing passes through the flow passages with a heat exchange occurring between hot oil passing along the flow passages and cool air passing by the external vanes. Oil exiting an outlet end of the flow passages passes through a filter to reach an outlet of the housing. In a preferred embodiment, two alternative flow paths are provided. A first flow path provides only filtration. A second flow path provides both cooling and filtration.

Abstract: A model gun with automatic bullet supplying mechanism comprises a pressure accumulating chamber from which a gas leading passage extends, a slider movable along a barrel structure, a pressure receiving portion fixed in the slider at the back of the barrel structure, a movable member provided with first and second inner spaces and arranged at the back of a bullet holding chamber, a passage connecting portion provided at the outside of the movable member for connecting the gas leading passage to the first and second inner spaces in the movable member, and a movable valve provided in the passage connecting portion. The movable valve is operative selectively, during a period in which the gas leading passage is connected through the passage connecting portion to the first and second inner spaces in the movable member, to cause gas derived through the gas leading passage from the pressure accumulating chamber to act through the first inner space in the movable member on a sham bullet in the bullet holding chamber and to shut off gas flow to the bullet holding chamber through the first inner space in the movable member from the gas leading passage so that the gas derived through the gas leading passage from the pressure accumulating chamber acts through the second inner space in the movable member on the pressure receiving portion to cause the pressure receiving portion to move back in company with the slider.
Patent CA-2250998-A1 (CA)
Inventor: NEGRE GUY
IPC: F02B15/00
Filed: 1997-04-14
Abstract: Procedure and devices relating to a cyclical internal combustion engine with a constant-volume independent combustion chamber in which, for each working cylinder or element, combustion chamber (1), combustion chamber (2) and expansion chamber (4) are made up of three separate, entirely independent parts. The cycle of the compression chamber is advanced in relation to that of the expansion chamber, in order to allow for lengthy combustion periods. The compressed carbonized mixture is introduced into combustion chamber (2) once its flap (6) has opened, shutting off a conduit (5) between the compression chamber and the expansion chamber; once flap (6) is closed, combustion takes place in the constant-volume independent chamber, which is isolated for an extended period. When the volume of expansion chamber (4) is at its lowest level, flap (8) is opened, shutting off conduit (7) between the combustion chamber and the expansion chamber, and the gases burned under high pressure expand, pushing back piston (15) and creating the working cycle. All engine applications are concerned.

Title: Reduction of interference in discrete multi-tone (dmt) based communications systems
Inventor: KUSTKA GEORGE JOHN
IPC: H04J11/00
Filed: 1999-01-12
Abstract: An Asymmetric Digital Subscriber Loop (ADSL) Discrete Multi-Tone system has disjoint and adjacent upstream and downstream channels. During the training phase of an ADSL connection, an ADSL DMT transmitter first determines a round trip propagation delay by transmitting a ranging signal to a far-end ADSL endpoint. During the subsequent communications phase, the ADSL transmitter synchronizes transmission of DMT  symbols to a reference clock. In addition, the cyclic extensions of each DMT symbol are increased as a function of the propagation delay.

Title: Inhibitors of oleamide hydrolase
Inventor: HENRIKSEN STEVEN J
IPC: C07C235/28
Filed: 1997-06-26
Abstract: Inhibitors of oleamide hydrolase, responsible for the hydrolysis of an endogenous sleep-inducing lipid (1, cis-9-octadecenamide) were designed and synthesized. The most potent inhibitors possess an electrophilic carbonyl group capable of reversibly forming a (thio) hemiacetal or (thin) hemiketal to mimic the transition state of a serine or cysteine protease catalyzed reaction. In particular, the tight binding .alpha.-keto ethyl ester 8 (1.4 nM) and the trifluoromethyl ketone inhibitor 12 (1.2 nM) were found to have exceptional inhibitory activity. In addition to the inhibitory activity, some of the inhibitors displayed agonist activity which resulted in the induction of sleep in laboratory animals.

Patent CA-2275828-A1 (CA)
Title: Using discrete message-oriented services to deliver short audio communications
Inventor: DOLAN MICHAEL FRANCIS
IPC: H04B14/04
Filed: 1999-06-21
Abstract: Delivery of short audio communications to remote end user devices uses discrete message-oriented service messages for delivery of the audio messages. Audio information is captured, encoded by means of audio compression technology, and stored at a message center. Alternatively, the audio information may be stored in an uncompressed format and compressed immediately before delivery. The compressed audio information is transmitted by means of Short Message Service or another discrete message-oriented service to the end user device, where it is decompressed and played to the recipient. Message delivery can be accomplished in parallel with some other ongoing activity at the end user device. The major fields in a Short Message Service message used to carry encoded audio information are a Type of Data field, including information on the type of translator needed to decompress the message field, a Short Message Identifier, a Length field, and the coded audio information. If the audio information is too large to be contained in a single Short Message, segmentation and reassembly techniques commonly known in the art are applied to break the information into segments, each of which is placed into a separate Short Message having the fields: Type of Data; Short Message Identifier; Total Segments; Number of Enclosed Segment; Segment Length; and Coded Audio Information Segment. At the end user device, the Short Message can be stored until the end user listens to the audio information. The intervening network can be a radio link, the Internet, or some other network.  The invention may also be utilized by a mobile user to send short audio messages to a message center and/or a second end user device.
