Abstract: A bite detector for use in rod fishing comprises a movement detector for detecting movement of a fishing line, and an indicator for indicating such movement to a user.  The bite detector has a tensioner to act on the line between the movement detector and the reel.   The tensioner draws line through the movement detector in the event that tension in the line between the detector and the hook is reduced.  The indicator gives a first signal in the event that the line moves in a first direction and a distinct second signal in the event that the line moves in the opposite direction.  By means of that arrangement, a user is informed of the direction of line movement when a bite occurs.

Patent CA-2212208-A1 (CA)
Title: Method and apparatus for continuous refractoryless calcining of gypsum
Inventor: ROWLAND GEORGE E
IPC: C04B11/028
Filed: 1996-02-01
Abstract: A method and apparatus is disclosed for the continuous calcining of gypsum material in a high-efficiency, refractoryless kettle preferably heated by a multiple series of separate immersion tube burner coils, each coil operating within a specific calcining zone inside the kettle. The lowest, i.e., initial, burner tube coil is formed with a low profile to permit use of a small initial gypsum charge, and hence, a quick kettle start-up cycle. That low profile initial burner design also helps keep the agitator motor's load at a minimum during cycle start-up. Due to the immersion tube burner coil construction, no refractory structure for the kettle is required. Also, no separate hot pit structure is required, as the kettle is used to merely hold the material being calcined and no residual heat is present. A relatively thin kettle can be constructed, as it needs only withstand relatively low operating temperatures. The kettle's staged, interiorly-disposed burner tube coils act to directly transfer burner tube heat to the kettle's contents, and the coils exhaust exteriorly of the kettle. The present calcining method and apparatus permit substantially improved tonnage output of calcined material, for a kettle of a given size. A modification to the present apparatus includes structure for recovering and recycling a portion of the spent burner gases, and also separate structure for forced aeration air, both preferably for introduction through the kettle bottom. One alternate embodiment concerns a differently-shaped kettle design. Another altercate embodiment concerns a modified kettle which uses a single immersion burner tube coil to provide the total heating of the kettle's contents, for use in certain calcining applications.

Filed: 1996-07-18
Abstract: Aspects of the invention provide a method and apparatus for controlling call acceptance in a telecommunications network comprising periodically measuring the volume of traffic being handled at a node of the network; for each measurement, identifying a corresponding one of a set of storage locations and incrementing the value stored in the identified location; determining from the stored values in said set an index of variation of measurement distribution;  and, in the event that the index exceeds a threshold value, intervening to re-route or reject calls for that node. By measuring the volume of traffic and determining a variation of measurement distribution it is possible to detect when the network is apprroaching a chaotic condition, that is to say, becoming unstable. The greater the variation of measurement distribution the more chaotic the network is becoming.
Patent CA-2225507-A1 (CA)
Inventor: NEIHEISEL GARY L
IPC: B23K26/12
Filed: 1997-12-22
Abstract: The invention relates to a process and apparatus for using laser radiation to remove an oxide layer (scale) from a hot rolled or annealed steel strip (40) by vaporization traveling in a gravitationally vertical direction at a speed of at least 10 m/min. The process includes utilizing electromagnetic radiation from a high power laser such as a free electron laser whose radiation has a surface power density of at least about 5 MW/cm2 at a point of contact with the metal strip surface. The radiation is passed through an optical system of aligned lenses or mirrors for focusing the radiation into a straight line projected transversely completely across the strip. The radiation has a pulse width less than 100 picoseconds, a pulse repetition rate greater than 10 MHz and a high average power of at least 10 KW. A radiation beam (56) is passed through a homogenizer (60) having a linear diverging lens (74) for spreading the radiation in a linear transverse direction. The radiation is passed through a cylindrical convergent lens (78) or a long cylindrical mirror (132) and focused into a straight line beam (36) projected completely across the width of the strip to remove the oxide by vaporization by the interaction of one or more or the spatial elongated laser pulses thereby forming an oxide free surface. A sealed interaction chamber (90) contains a non-oxidizing gas (108), a slotted entry (91) for receiving the oxidized strip, a slotted exit (92) for a passage of the as-cleaned strip, at least one elongated window (93) for receiving the radiation into the chamber, an exhaust duct (94) for removing the non-oxidizing gas ladened with oxide debris from the chamber and a filter (106) for removing oxide powder from the gas. The non-oxidizing gas is directed into the chamber at a point just above a plasma plume (112) and just beyond incident focused radiation beam (36) through a long slot-like gas nozzle (114). By keeping the chamber sealed from the ambient atmosphere and by maintaining sufficient non-oxidizing gas adjacent to the plasma interaction zone and the cleaned metal surface, reoxidation of the cleaned steel surface can be prevented.

Title: Clutch actuator
Inventor: BAER KURT
IPC: F16D23/14
Filed: 1997-12-29
Abstract: A clutch actuator includes an outer cylinder housing having a plurality of rampsformed on an inner cylindrical surface thereof. Each of the ramps has a radiallyinwardly facing surface which includes a forwardly facing tapered surface and a rearwardly facing tapered surface. A hollow cylindrical piston is disposed concentrically within the outer cylinder housing and has a plurality of axially extending protrusions formed thereon. Preferably, the number of such protrusions is equal to the number of the ramps formed on the outer cylinder housing, and the protrusions are circumferentially interleaved within the ramps formed on the outer cylinder housing. Each of the protrusions has a radially outwardly facing surface which includes a forwardly facing tapered surface and a circumferentially extending groove. An inner cylinder housing is disposed concentrically within the piston. The outer and inner cylinder housings are fixed in position and define an annular chamber within which the piston can reciprocate axially. The piston is connected to a release sleeve of a clutch by means of a snap ring which is disposed within the grooves formed in the protrusions of the piston. Thus, the piston is connected to the release sleeve for axial movement therewith to operate the clutch. To disconnect the clutch actuator from the clutch, the piston is moved axially to a point where the snap ring engages the rearwardly facing tapered surfaces provided on the ramps of the outer cylinder housing. The rearwardly facing tapered surfaces provided on the ramps move the snap ring out of the grooves formed in the protrusions, thereby disconnecting the piston from the release sleeve.
