Patent CA-2249282-A1 (CA)
Inventor: CONNELL STUART A
IPC: E21B17/10
Filed: 1997-03-14
Abstract: A removable guide member for guiding drill string components in a drill hole includes an elongated body having a centerline axis with a bore extending along the axis. The body terminates in a head end having a preselected radial dimension with respect to the centerline axis. The guide member is adapted to be threadably connected to adjoining drill string components. The head end radial dimension is preselected to space an outer surface thereof in close proximity to a drill hole sidewall, so that if the drill string begins to deviate out of alignment, the outer surface of the head end will contact the drill hole sidewall to stabilize alignment. The guide member can be inserted into any position along the drill string.

Title: Modular fuel tank assembly, vehicle mounting arrangement and method for installation
Inventor: AMMER JOHN M
IPC: B60K15/067
Filed: 1998-11-17
Abstract: A mounting arrangement for a modular component such as a fuel tank for a vehicle such as a truck and a method of installing same on the vehicle. The method is accomplished via a combination of a set or sets of two brackets and an initial alignment means for each set of brackets. The initial alignment means is comprised of two mating components, with one mating component being a portion of one bracket and the other mating component being a portion of the second bracket. One bracket of each set is installed directly to a portion of the vehicle under manufacture, such as to the frame rail. A modular assembly is assembled separately with the second bracket of each set installed on the modular assembly. The sets of brackets are joined via the initial alignment means attaching the modular assembly to the vehicle. Final attachment may then be made between the set or sets of two brackets and hence the modular assembly and the vehicle, while the modular assembly is held into proper position via the initial alignment means.

Title: Gas turbine cooled moving blade
Inventor: TOMITA YASUOKI
IPC: F02C7/12
Filed: 1998-04-17
Abstract: Gas turbine cooling moving blades, wherein a cooling air supply path is shortened to prevent possible temperature rise of a cooling air and suppress pressure drop until the cooling air reaches the blades. Cooling air passages (16) are formed in a casing wall below first stage stationary blades (11) with one end (16a) thereof opened toward a casing and the other end (16b) thereof opened toward a space (13). The cooling air passages (16) are oriented to permit the cooling air to jet toward air flowing holes (6) provided in shank portions (4) below platforms (2) of moving blades (1), flow into the shank portions (4) from the air flowing holes (6) and enter the moving blades (1).  Since axes (17) of the cooling air passages (16) are deviated at an angle, which is determined by a speed of the cooling air jetting from the cooling air passages (16) and a revolving speed of the moving blades (1), in a circumferential direction from positions of the air flowing holes (6) when the moving blades (1) are stationary to align with the stationary blades (11) in an axial direction, the cooling air can be oriented and jetted in an optimum direction over a shortest distance. Accordingly, temperature rise and pressure drop are suppressed to the minimum.

Patent CA-2282210-A1 (CA)
Title: Child-resistant container
Inventor: WOLFE STEVEN R
IPC: B65D83/04
Filed: 1999-09-15
Abstract: A child-resistant compact or tablet case of one-piece molded plastic construction made up of a generally flat rectangular base and a cover top interconnected by an integral "living" hinge. A pair of mating lip flanges extend one each along the front edges of the base and top, i.e., the edges remote from the hinge. Each flange has an arcuate recess, and these recesses are mutually offset from each other laterally of the case when it is closed with the flanges lying against one another. By placing a thumb in one recess, and the tip of the forefinger in the other recess, a pry-open force may be applied to thus readily open the case. Since only one recess is visible when viewing the case from the top or the bottom, this manner of opening the case is not readily apparent to an infant or young child, but is very easy for an infirm or elderly adult to comprehend and use for opening the compact case merely by forger feel. In addition, the base has a pair of latch spring fingers disposed one on each of the laterally opposed sides near the front edge of the base and that protrude upwardly from the base bottom wall in cantilever fashion. The top has a cooperating pair of pockets that receive the free latch-tang ends of the spring fingers to render there exterior-accessible in the closed condition of the case. The outer edges of these pockets form the strike portion of the latch system.  To open the case, squeeze pressure must be applied with one hand simultaneously to both of the spring finger tang ends to move them to unlatched condition, and then to hold them in this condition while, also simultaneously, with the other hand pry-open pressure is applied to the two front lip flanges at the aforementioned offset recesses. This two-handed operation further resists opening by a child because of its complex dual-hand-manipulative coordination requirement.
