Title: Laptop computer support
Inventor: TONN ROBB
IPC: A47B23/04
Filed: 1998-07-08
Abstract: The laptop computer support is for use in supporting a laptop computer on a top of a desk adjacent an edge of the desk. The laptop computer support supports the laptop computer such that a front end of the laptop computer extends past the edge of the desk to a position just above the lap of an individual sitting at the desk. The laptop computer support has a plate member for engaging a bottom surface of the computer supporting the computer. A flange is fixed at the front end of the plate member and extends laterally across at least a portion of the plate member projecting outwards from the top surface of the plate member. The flange engages the front end of the laptop computer and prevents the computer from sliding forwards and off of the laptop computer support. A leg is connected to the plate member and supports the plate member on the desk top at one of a plurality of angles to the top of the desk, and at least one foot member engages the top of the desk adjacent the edge of the desk. The foot members are attached to the bottom of the plate member adjacent the front of the plate member and are spaced downwards from where the leg is connected to the plate member.

Title: Medical electrical lead
Inventor: SWOYER JOHN M
IPC: A61N1/05
Filed: 1997-03-14
Abstract: A transvenous bipolar lead (1) specifically designed for coronary sinus implantation. The lead has essentially two main characteristics, the distal end has a 45-degree pre-shape to facilitate introduction of the lead through a catheter and provide optimal positioning of the lead (1) within the coronary sinus. The lead further features a distal electrode tip (20) which itself is canted at an angle of 45 degrees on the distal end of the lead to provide a very close contact with the coronary sinus upper wall and, thus, with the left atrium inferolateral wall. In addition, each of these sections (51, 53) is flexible to permit the lead to be introduced through a relatively small-sized guide-catheter. Finally, the lead further features a center lumen to also permit the lead to be straightened for introduction with a stylet.

Filed: 1997-06-16
Abstract: Fuel-air mixture apparatus (1) has a body (2) adapted for connection via a flange (3) to an air cleaner housing (3') and to an engine inlet manifold (4'). In the body (2) is arranged a primary air passage (5) having an inlet (6), an adjustable throttle (7), a throat (8) and an outlet (9). The throttle will be connected in use to a speed control device for the engine via a linkage (10). Also provided in the body (2) is a secondary air passage (13) having an inlet (14) from the air cleaner housing and an outlet (15) to the primary air passage (5) at the throat (8). Towards its down-stream end, the secondary air passage opens into a chamber (16), with the opening (17) being arranged tangentially to the chamber to induce swirling air flow in the chamber. The outlet (11) is provided axially of the chamber. At the other end of the chamber, in a bore (18) in the body a nozzle device (21) is provided. It has a circumferential void (24) to the body. This void has a fuel supply bore (25) in the body (2) and connected to a continuous fuel pump opening into it. A  fuel inlet (26) leads from the void to an internal bore in the sleeve (22). Slidably mounted in the sleeve is a guide (27), sealed to the sleeve via a gland (28). The outside end of the guide carries a compression spring (29) and the end of the guide is closed by a plug (30) providing an abutment for the spring, whereby the guide is urged outwards. The guide has a bore (31) in which a needle (32) is slidably mounted. The arrangement is such that when the plug (30) is pushed fully inwards of the body, as on closure of the throttle, the needle closes the aperture (38) and the fuel supply to the engine, but the force with which the needle is urged into the aperture is regulated by the internal spring (33). In use, the plug (30) is acted on by an abutment member (40), which is movable in step with the throttle (7) via a branch of the linkage (10). The linkage is designed to ensure that the stoichiometrically required amount of fuel is provided for the throttle opening.

IPC: F01D5/20
Filed: 1998-06-18
Abstract: A tip shroud for a moving blade, which is made thin and light to be used at a gas turbine downstream stage which is improved in the flow of cooling air to enhance the cooling efficiency. Cooling air holes 13 to 16 of a slot shape are formed in a tip shroud 11 of a moving blade 10 and are opened in two side faces to release the cooling air from the inside of the moving blade 10. In the upper face of the tip shroud 11, there are formed cooling air holes 20 which communicate with the higher pressure side in a combustion gas flow direction R to release the cooling air so that the cooling air flows from the higher pressure side to the lower pressure side to cool a high stress portion Y. A high stress portion X is likewise cooled with the cooling air coming from the adjoining moving blade. The slope shapes of the cooling air holes 13 to 16 allow the cooling air to flow widely thereby to cool the face of the tip shroud 11, and the cooling air holes ?0 cools the high stress portions X and Y effectively.

Abstract: Locking apparatus is mounted to a wall or inside a bag-supporting container. The fluid-storage bag has a tubular fitting with axially spaced flanges forming an annular locking area. The locking apparatus comprises a diaphragm mounted over a port formed in the wall. The diaphragm has a opening formed therein which has a size and polygonal profile which matches the polygonal perimeter of the fitting's locking area. Cuts extending radially from the vertices of the polygonal opening form radial flaps. The outermost flange is larger than the diaphragm opening and when forcibly pushed through the diaphragm opening it deflects the flaps. Once the outermost flange passes axially through the flaps, the flaps snap back flexibly and engage the fittings locking area, resisting fitting removal. The complementary polygonal tubular perimeter and diaphragm opening resist rotation aiding in installation of threaded accessories. A removable plug is provided for installation to port outside of the wall which, when installed, seals any fluid within the walled enclosure.
