Patent CA-2119292-A1 (CA)
Inventor: HAJO HELMUT
IPC: C21D9/63
Filed: 1994-03-17
Abstract: During thermal treatment of continuously moving metal bands no heat is supplied over a part of a treatment path to edge regions of the band per surface unit than to the center region of the band.  This prevents formation of a wavy shape  in  the  edge  regions  of  the metal  band which  is advantageous for a further treatment.
Patent CA-2120795-A1 (CA)
Inventor: MALLOY GARY J
IPC: B29C33/76
Filed: 1994-04-07
Abstract: Reusable core apparatus (10, 12, 14, 16) for a casting mold (1) is disclosed. The apparatus includes a first core mechanism (10, 12) for being disposed in a casting cavity (2) of the mold to define a first internal casting surface within the cavity, a second core mechanism (14, 16) for being disposed in the casting cavity to define a second internal casting surface in the casting cavity, and an aligning and securing mechanism (22, 24, 30, 32, 36, 42) for securing the first and second core mechanisms together in a predetermined engaging relationship within the casting cavity. The aligning and securing mechanism comprises cooperating joint members formed integrally with the first and second core means. The cooperating joint members maintain the first and second core mechanisms in the predetermined engaging relationship while an article is being cast in the mold and permit the first and second core mechanisms to be moved away from each other out of the predetermined engaging relationship after the casting process so that the first and second core mechanisms may be directly and easily disengaged with each other and from the cast article and subsequently reused in casting additional articles. The apparatus also includes a mechanism, including a magnet disposed with one of thecooperating joint members, for maintaining the first and second core mechanisms in a temporary engaging relationship as the core mechanisms are being assembled together.

Title: Negative electrode for gastight alkaline storage batteries having a carbon-black-containing gas-consumption layer
Inventor: KLAUS CHRISTOPH
IPC: H01M10/34
Filed: 1994-08-09
Abstract: Abstract of the Disclosure A carbon-black-containing gas-consuming layer on the surface of a negative electrode is produced from a mixture of an aqueous carbon black dispersion and an aqueous PTFE dispersion, both of which contain a surfactant of the same type (either cationic, anionic or nonionic) for the purpose of stabilization.          The stabilized particles in the final gas-consuming dispersion are formed by coating PTFE particles with smaller carbon particles, preferably with an interlayer or envelope of a surfactant film.  Pores and cracks operate to increase the effective catalytic surface area for oxygen gas.  Additions of polyacrylic acid esters are suitable for adjusting the viscosity of the dispersion.  The dispersion is applied to the electrode by immersion or spraying.

Patent CA-2135674-A1 (CA)
Inventor: KUPKA MARTIN
IPC: B01D33/00
Filed: 1993-05-12
Abstract: A filtering device is disclosed having tubular filtering elements (8) made of perforated tubes (54) on the outer side of which are arranged filtering media (55). The liquid to be filtered flows against the filtering bodies (8) transversely to the axis of the tubes. Preferably, the filtering bodies (8) are arranged in a circular ring, are mutually linked into a cage and form a rotor (5) which rotates in a container (1) for the liquid to be filtered. Several such cages may be concentrically arranged inside each other, and adjacent cages turn in opposite directions. Pulsating currents are thus generated in the liquid to be filtered which prevent the filtering media (55) from being prematurely clogged by sediments.

Title: Remote control for a plug-dropping head
Inventor: BAUGH JOHN LINDLEY
IPC: H04B10/10
Filed: 1994-05-23
Abstract: An apparatus and method of dropping a pumpdown plug or ball is revealed. The assembly can be integrally formed with a plug-dropping head or can be an auxiliary feature that is mounted to a plug-dropping head. The release mechanism is actuated by remote control, employing intrinsically safe circuitry. The circuitry, along with its self-contained power source, actuates a primary control member responsive to an input signal so as to allow component shifting for release of the pumpdown plug or ball. Multiple plug-droping heads can be stacked, each responsive to a discrete release signal.     Actuation to drop the pumpdown ball or plug is accomplished even while the components are rotating or are moving longitudinally. Using the apparatus and method of the present invention, personnel do not need to climb up in the derrick to actuate manual valves. There is additionally no need for a rig floor-mounted control panel with hydraulic lines extending from the control panel to remotely located valves for plug or ball release.

Patent CA-2141773-A1 (CA)
Title: Peening tool for cold working aluminum alloy edges and holes
Inventor: MAHONEY MURRAY W
IPC: C22F1/04
Filed: 1995-02-03
Abstract: A peening tool imparts cold working to produce a localized fine grain surface morphology in and around fastener holes and edges in aluminum materials. The tool may comprise a hollow housing with openings for retaining a plurality of ball peens that may be driven by rotating cams or an oscillating tapered piston operating within the housing to force the ball peens to impact the surfaces of an edge, cavity, or fastener hole to which the tool is applied. The tool may be shaped to accommodate straight bored, counter bored, countersunk, and/or edge surfaces and may be applied manually or automatically for cold working over substantially the entire surface area of the edge or cavity. The peening tool effects localized cold working to a predetermined and controlled depth to break up the existing large pancake-shaped grain structure in the surface of the aluminum alloy. After the surfaces have been cold worked, rapid heating recrystallizes the cold worked surfaces to attain a localized fine grain corrosion and fatigue resistant microstructure. The process provides the benefits of exfoliation corrosion resistance and improved fatigue life by using microstructural control rather than chemical coatings that may be harmful to the environment. The process produces a stable microstructure that allows subsequent use of other treatments to act in parallel as multiple barriers to corrosion.

IPC: G01N15/08
Filed: 1993-11-08
Abstract: 2148807 9411721 PCTABScor01 An ultrasonic detection apparatus (1) is disclosed for detecting defects in filters (3). The apparatus (1) operates on a wetted filter (3) and includes a housing (2). The wetted filter (3) divides the housing (2) into an inlet side (7) and an outlet side (8).  Both the inlet side (7) and the outlet side (8) may be filled with a gas as with a standard forward flow test apparatus. A  microphone (4) is disposed in the vicinity of the wetted filter (3). The microphone (4) receives acoustic signals generated within the chamber (any combination of inlet side (7), outlet side (8), inlet tube (5), or outlet tube (6)) as a result of the increased pressure on the inlet side (7). A signal processing device (9) is also included for analyzing the acoustic signals received by the microphone (4) for determining whether a filter (3) is defective. The invention includes multiple methods for determining whether a filter (3) is defective. One method may include the steps of placing a wetted filter (3) in a test housing (2) to divide the test housing (2) into an inlet side (7) and an outlet side (8), pressurizing the inlet side (7) with gas, measuring both the gas flow and the sound volume on the outlet side (8), and thereby determine whether the filter (3) is defective.
