Title: Method for injecting fluid into a wellbore
Inventor: WILSON WILLIAM NEAL
IPC: E21B33/16
Filed: 1996-01-11
Abstract: A method for injecting fluid, such as an accelerator, into a wellbore comprises storing the fluid in a reservoir, locating the reservoir downhole in the wellbore, and then transferring the fluid from the reservoir into the wellbore. More particularly, one embodiment of the method comprises storing the fluid in a reservoir in a plug, pumping the plug down casing in a wellbore, and transferring the fluid at the bottom of the wellbore via a venturi effect. Another embodiment of the method comprises storing the fluid in a reservoir integrated into the wall of a portion of casing, setting the casing in the wellbore, and then transferring the fluid via a venturi effect from the reservoir into the annulus defined between the casing and the wellbore.
Patent CA-2211058-A1 (CA)
Title: Adjustable spacing tool
Inventor: RESTELLI STEPHEN C
IPC: E04G21/18
Filed: 1997-08-06
Abstract: The present invention is a tool for spacing frame members having an elongated body which has a first and a second track.  A cradle, formed by a first head and a second head, can be adjusted to accommodate a first frame member of width W, and a shoulder, formed by a third head, can be spaced apart from the cradle to engage a second frame member, separated from the first frame member by a spacing interval I.  Each of the heads slidably engage the first track and the second track of the elongated body, and each have an indexing face which is substantially normal to the elongated body.  The heads are lockable with respect to the first and second tracks. Preferably, the elongated body has a bubble level to aid in identifying when the body is horizontal.  When a bubble level is employed, each head has a levelling surface, the levelling surfaces being co-planar, providing a discontinuous reference surface for levelling.  Preferably, the elongated body is provided with indicia to indicate standard values for the spacing interval I.  A fourth head may be provided, and the third head and the fourth head form a second cradle.  The heads may be configured to be adjustably attachable to a preexisting beam level, which then serves as the elongated body of a spacing tool, and therefore have utility in their own right.

Abstract: A lock system has a lock cylinder pivotal about an axis between a pair of end positions and through a center starting position, a key fittable into the cylinder and actuatable to pivot the cylinder between its positions, an arcuate magnet centered on the axis and coupled to the cylinder for joint movement therewith, and a pair of angularly spaced Hall-effect sensors adjacent the magnet, trippable by the magnet to generate respective outputs, and positioned such that in the central position the magnet is closely juxtaposed with and trips both sensors, in one of the end positions the magnet is closely juxtaposed with and trips only one of the sensors and is spaced from the other of the sensors, and in the other end position the magnet is closely juxtaposed with and trips only the other sensor and is spaced from the one sensor. The sensors and magnet are so constructed and relatively positioned that on pivoting of the magnet through a predetermined angle in one direction from the center position the one sensor is tripped and on pivoting of the magnet through the predetermined angle in the other direction the other sensor is not tripped. A lock system connected to the sensors has an antitheft mode initiated by the sensors on displacement of the cylinder into the antitheft end positions and provided with a latch operable on displacement of the cylinder into the lock/unlock end position.

Title: Implantable hearing aid
Inventor: LESINSKI S GEORGE
IPC: H04R25/00
Filed: 1996-09-19
Abstract: A hearing aid (10) includes an implantable microphone (28), signal-processing amplifier (30), battery, and microactuator (32). The amplifier (30) amplifies and processes a signal from the microphone (28) for application to the microactuator (32). The microactuator (32) is implanted to mechanically create vibrations in perilymph fluid (20a) within a subject's inner ear (17). A transducer (45) of the microactuator (32) is preferably a circular disk, 2 to 8 mils thick, of stress-biased PLZT. Such disks can be mounted as drumheads, preferably in conjunction with a flexible diaphragm (53, 56, 57), to a threaded metal tube (46), e.g. 1.4 mm in diameter and 2.0 mm long. The tube (46) is implanted into a fenestration in the promontory (18) of a subject's inner ear (17). Securing the disk-shaped transducer (45) to a tube (46) having a diameter larger than the fenestration and filling the tube (46) with fluid (58) provides hydraulic amplification for the transducer's displacement. The microphone (28) is preferably fabricated from a thin sheet of PVDF overcoated with inert metal electrodes (42a, 42b).

Inventor: COLLIS TODD M
IPC: H01H9/26
Filed: 1998-08-07
Abstract: Disclosed is a mechanical interlock assembly (10) for use within an electronics enclosure (62) for preventing actuation of a service breaker switch (18) when a main breaker switch (17) is actuated. The mechanical interlock assembly comprises a bracket (14), an arm (15) and a spring (16). The arm and spring are retained in a bracket which is mountable within the electronics enclosure adjacent the service breaker switch and the main breaker switch to selectively prevent unwanted actuation of the switches. The arm is slidable along a generally axially non-movable pin (24) which extends axially between a first side wall (19) and a second side wall (20) of the bracket. The spring is retained along the pin between the arm and the first side wall of the bracket, and the spring loads a force between the arm and the first side wall of the bracket when the arm is displaced along the pin. The spring presses the arm against a toggle lever (25) of the service breaker switch after the arm has been displaced and the toggle lever of the service breaker switch has been actuated. An arm supporting panel (54) of the bracket prevents the arm from rotating about the pin.
