Patent CA-2081093-A1 (CA)
Title: Anisotropic transducer
Inventor: CULP GORDON W
IPC: H02N2/00
Filed: 1992-10-21
Abstract: ABSTRACT OF THE DISCLOSURE     This invention relates to an actuator which changes its length without   changing   its   width or   breadth   dimensions.   Four   shear electrodeformable bodies 4 are placed symmetrically on two faces of a central  electrode  6.  Each  body  also  has  a  connecting  electrode  8, attached to the electrodeformable body, thus forming a tetramorph which is the basic building block of the actuator.  Each connecting electrode allows the tetramorphs to be attached to each other in layers and stacks to the desired dimensions of the actuator. Two of the electrodeformable bodies in the top half of the tetramorph are polarized to shear in one direction and the two electrodeformable bodies  in the bottom half are polarized  to  shear  in  the  opposite  direction.  If  the  shear  in  the electrodeformable bodies is up and down the tetramorph acts as a lifter.          If the shear in the electrodeformable bodies is sideways the tetramorph is a tangenter or axier.

Abstract: A pneumatic terminal block assembly worn by a pilot couples breathing gas from a regulator to the pilot's breathing mask.  An emergency breathing gas supply attached to the pilot's seat remains with the pilot during ejection and supplies high pressure breathing gas to an emergency regulator which is part of the terminal block assembly.  The emergency regulator on the terminal block is coupled to the emergency breathing gas supply by a small diameter high pressure hose which is not susceptible to tearing or kinking during ejection caused by the blast of oncoming air.

Title: Well rig lift system and a hydraulic energy-storing well rig lift system
Inventor: XINYI GU
IPC: E21B19/08
Filed: 1992-12-10
Abstract: A well rig lifting system and a hydraulic energy-storing well rig lifting system, wherein a high pressure energy-storing cylinder and a composite cylinder or cylinder group are used to carry out the lifting and lowering operations. During the lifting operation, a power machine under a substantially constant load continuously pumps oil to the energy-storing cylinder, and communication relationships of the energy-storing cylinder with various chambers of the composite cylinder or cylinder group is selected to provide an appropriate lifting force to lift the pipe string. Therefore, the installed capacity of the power machine can be reduced to 1/3-1/4 of that in a conventional lifting system. During the lowering operation, communication relationships of the energy-storing cylinder with various chambers of the composite cylinder or cylinder group is selected to provide an appropriate lifting force grade less than the gravity of the pipe string, so as to utilize the energy-storing cylinder to recover the potential energy released during the lowering of the pipe string. The recovered energy can then be used to carry out auxiliary operations during the lowering operation, and therefore no power machine is needed to run. The recovered energy can also be used in power generation, heating, etc.

Title: Shank-attached packer assembly
Inventor: PROSKO RICK
IPC: A01B35/32
Filed: 1993-03-25
Abstract: ABSTRACT An improved packer apparatus in which the means of applying pressure downwards on the packer wheel, a coil spring in the example, is at the point of pivotal attachment of the wheel mounting bracket to the cultivator shank. This allows the packer assembly to be very compact and have few moving parts, and in consequence it causes no interference to the shank when an obstruction is struck, is in less danger of breakage, does not exert upwards pressure on the shank, and has greater freedom of movement than earlier packer assemblies. The described example can also allow for varying the packing pressure by reversing the spring or connecting the wheel mounting bracket through a different hole in the bracket, or both. A neoprene bushing ensures trouble-free, grease-free maintenance of the one only moving part in the attachment/pivot assembly.

Abstract: The extended error correction process of the present invention corrects (106) error of a data message that has been transmitted a plurality of times. The process first receives the data message at least twice, logically combining the first and second messages received to form an error indication word (101). The error indication word is then used to locate the error locations in each message after which some of the errors are complemented (106), depending on the total number of errors found. The message is then decoded (104) and used for transmit power changes, channel reassignment, to release a call (140), etc.

Title: Method simulating data traffic on network in accordance with a client/server paradigm
Inventor: HANES CHARLES F
IPC: H04L69/40
Filed: 1993-10-25
Abstract: A method for modeling traffic on a network according to a Client/Server paradigm is disclosed. The method includes the steps of exctracting the model parameters from known or measured interactions between a client node running a particular application and a server node with no other activity on the network. The method is repeated for each nodal configuration and for each application until the traffic for each node-application combination has been modeled with no other load on the network. Scripts are created from the Paradigm parameters and are used in conjunction with a traffic generator to create discreet events mimicking the traffic which would be generated from each node. The model will insure that the traffic generated by each traffic source will be adjusted as a function of the response of the network under the load created by all of the traffic loading the network. <IMAGE>

Abstract: A transistor mounting clamp assembly for ensuring reliable electrical connection of a power transistor electrical connector tab (typically the collector tab) to a metallized portion of an associated printed circuit board. The transistor mounting clamp assembly comprises a top and bottom clamp dimensioned for sandwiching therebetween the transistor tab. The clamp assembly uses a machine screw and associated Belleville washer for maintaining this urging relationship even when the components expand and contract. The bottom clamp preferably has a stepped region or other surface discontinuity for securing the connector tab thereto. The clamp assembly further comprises an extending tab which is secured to the top clamp and which has a second region for providing electrical connection to the metallized portion of the printed circuit board by soldering, or other means. The overall transistor mounting clamp is able to withstand thermal expansion and contraction associated with intermittent operation of the associated power transistor and is also able to make reliable electrical connection to associated tabs of matching network elements typically used in transistor amplifier applications associated with ultra-high frequency and microwave operations. The clamp assembly can also be used to secure electrical connector tabs of other typically high-powered devices, and thus is not limited to power transistor applications.

Title: Electric cable termination fittings
Inventor: HEATHERINGTON ROY I
IPC: H02G15/04
Filed: 1994-01-14
Abstract: An armor or sheild  grounding arrangement for cable terminations in which contact fingers, rather than being flexible, are substantially rigid. In the initial (as sold) form, the fingers are radially clear of the passage through the center of the fitting into which the prepared cable end is to be inserted; when the cable is in place (preferably as the fitting is screwed up in the ordinary way) the fingers are bent beyond their elastic limit to engage the layer of the cable to be grounded.          Subsequent flexing of the fingers is minimal and the risk of fatigue fracture practically eliminated without the need to embed the fingers in resinous compound.  The fingers may in some cases be sharp enough to penetrate the outer jacket of the cable, eliminating the need to strip it back.
