Patent CA-2220390-A1 (CA)
Title: Chisels and scrapers with replaceable blades
Inventor: VASUDEVA KAILASH C
IPC: B25D3/00
Filed: 1997-11-07
Abstract: The hand tool has a shaft with a distal end which is configured to receive any one of a variety of different sized chisel or scraper blades or the like, via corresponding male and female dovetail connections, for example. Storage space for the extra blades, if desired, may be provided in the handle which is secured to the shaft, or may be provided via depressions in a panel of a tool case of the type commonly referred to as "gift cases". Where storage space is provided in the handle, preferably this is accomplished by virtue of a spring-loaded collar which overlies lower portions of elongated rotatable cover pieces, preventing rotation. When the spring-loaded collar is retracted, the cover pieces can be rotated, to reveal storage areas on either side of the handle.

Title: Capped synthetic rna, analogs, and aptamers
Inventor: OLSEN DAVID B
IPC: C07H21/00
Filed: 1996-06-03
Abstract: A method is provided for making synthetic capped RNAs. These compounds serve as substrates for the virally encoded endonuclease associated with influenza virus. We are able to assay for this unique and specific viral activity of cleavage of a capped RNA in vitro. Therefore, screening of inhibitors of this activity is possible. In addition, short non-extendible (due to their length or because of the modification of the 3'-end of the oligo, i.e. 3'-dA) RNAs are potent inhibitors of the cleavage of capped RNAs by influenza endonuclease. Finally, these compounds may be used to investigate viral and cellular mechanisms of transcription/translation or mRNA maturation.

Title: Hybrid deicer with element sequence control
Inventor: PUTT JAMES C
IPC: B64D15/16
Filed: 1998-01-20
Abstract: A deicer comprises a skin heating means  immediately subjacent an outer skin overlying an apex of a leading edge, and a skin deflection means immediately subjacent the outer skin chordwise aft of the apex.   The skin heating means prevents the formation of ice over the apex and the skin deflection means deflects the outer skin to expulse ice formed chordwise aft of the apex.  A controller controls the heating and deflection cycles to minimize power consumption of the deicer.

Inventor: ARENDS ALBERT W
IPC: B29C51/18
Filed: 1998-06-12
Abstract: Apparatus for forming articles in a thermoplastic sheet, severing the articles in the sheet, and stacking the articles in a stacking receiver.  The apparatus includes upper and lower molds moveable between closed positions in which the molds engage opposite sides of the sheet to differentially pressure form a part in the thermoplastic sheet.  The molds in which the article is formed are moved toward each from the closed positions to article trim positions to sever the article from the sheet.  The lower mold is then moved linearly away from the sheet in a vertical direction and then transversely moved in a second linear transverse path of travel to a remote discharge location. Apparatus is provided for reorienting the mold between its orientation in the first linear path of travel and its orientation in the second path of travel. The invention contemplates the method of transferring an article in a differential pressure forming and trim die linearly in one direction away from the sheet, rotating the die carrying the article, and then transversely moving it in a second line or transverse path to a remote discharge position where the part is discharged from the mold.

Patent CA-2246993-A1 (CA)
Inventor: LUEBBE BODO
IPC: G08B13/24
Filed: 1997-02-17
Abstract: It is known that an object can be detected in a region to be monitored by transmitting through the region a high-frequency scanning signal from one side of the region to an opposite second side thereof, where the signal is received in a transponder, modified and returned through the region to the first side. The modified scanning signal is received on the first side of the region and compared with a threshold value, an alarm signal being generated if this threshold value is violated. In order to optimize the threshold value (Uref1), a mean value (M) is continuously formed from the signal (U) compared with the threshold value (Uref1) and from this mean value (M) the threshold value (Uref1) is formed, taking account of a predetermined safety margin.

Filed: 1998-11-09
Abstract: A tool and method for plugging a service connection to a gas main in preparation for removal of the service tee removes the perforator, mills the hole in the main to provide a smooth seat for a sealing plug, and inserts a gas-tight sealing plug into the hole. The tool of the invention is operable through a narrow "keyhole" excavation, which decreases the risk to service personnel and significantly reduces costs of repairing the excavation. In the preferred embodiment the tool is loaded with a milling bit and a sealing plug before attachment to the service tee. The tool head is engaged to the service tee in a gas-tight fit to prevent the escape of gas during the procedure, and an adapter plate is pivoted between three working positions to perform the three steps of the service connection plugging method. In the preferred embodiment a pneumatic gear motor drives a hexagonal driver bit actuated by a linear actuator located in the shaft of the tool, the driving bit providing the required mechanical interface with each of the accessories involved in each step of the procedure. A separate pneumatic motor pivots the adapter plate between working positions, and specialized adapter is provided at each working position of the adapter plate allowing the same actuators to be used for the perforator removal, milling and plugging operations.
Patent CA-2255513-A1 (CA)
Title: One-piece swivel clip
Inventor: MEYER CHARLES
IPC: B29C45/00
Filed: 1998-12-08
Abstract: The device is a swivel clip with a relatively stationary base element and a relatively rotatable swivel element. The swivel element rotates about a shaft which passes through an aperture in the base element. The swivel clip is initially formed in one piece by molding windows in an upper portion of the swivel element which are opposed to molding windows in a lower portion of the swivel element (that is, alternating around the periphery of the shaft).      The windows meet in the base member, forming the swivel shaft, the swivel aperture and the internal gates as a single piece.      Subsequently breaking the internal gates provides vestiges which support the swivel shaft within the aperture.
