Abstract: A phase-controlled, sequential-gripping tube fitting includes a main fitting body (10) having a tube end receiving opening (24) with a tapered camming mouth (28) forming the entry to the opening. A front female (36) with a tapered forward nose surface (44) is engaged with the camming mouth (28) and includes a rear surface (46) with a conically tapered recess extending forwardly toward the nose surface (44). Extending into the conically tapered recess (46) of the front ferrule (36) is a rear ferrule (38) having a rear force receiving surface (60). A coupling nut (14) is threadedly connected to the main body (10) and has a force applying face (62) engaged with the rear force receiving surface (60) of the rear ferrule (38). An arrangement is provided to control outward buckling of the rear ferrule (38). The arrangement includes a central body (54) located between the nose portion (52) and the rear force receiving surface (60) of the rear ferrule (38).

Patent CA-2286940-A1 (CA)
Inventor: WHITEMAN STEPHEN LIONEL
IPC: A47G27/02
Filed: 1999-10-18
Abstract: This device has been conceived with the goal of eliminating the time and energy required to manually clear snow from one's walkway, i.e., with a snow shovel or broom. The device consists of a two-piece mat, one top mat, which sits squarely on a lower mat, designed to melt and siphon the melted snow out of the respective sides of the mat. This is accomplished by way of venting the top mat so that snow or freezing rain can fall through to the lower mat, which is equipped with a slightly graded reservoir which peaks down the lengthwise center much like a roof but only at about 2 degrees. When this reservoir is filled with salt or any other crystallized granular substance designed for the melting of snow, intermittent vents along the sides of the lower mat channel the water out of the mat and onto the sides of the walkway, for safety. This device could be implemented as soon as cold weather begins or as soon as the user receives a forecast of a snowfall. The device may be produced in varying sizes to adapt to numerous walkways, and could also be formatted to fit on stairs.

Title: Method of and device for optical fibre grating fabrication
Inventor: BOSCHIS LAURA
IPC: G02B/
Filed: 1999-12-20
Abstract: An optical fibre is sequentially submitted to a first and a second exposure to the grating writing radiation. The first exposure is performed by positioning the fibre in proximity of a phase mask, so as to expose the same fibre to a radiation of which the intensity is spatially modulated by the interference fringes generated by the phase mask itself. The second exposure is performed with the fibre spaced apart from the phase mask in the propagation direction of the writing radiation by a sufficient distance in order the radiation incident on the fibre is substantially defined by the first diffraction orders generated by the phase mask in a situation in which there is basically no reciprocal interference among said first orders.

Title: Method and apparatus for determining an operating point of a non-linear amplifier of a communication channel
Inventor: BETHSCHEIDER GERHARD
IPC: H04B17/00
Filed: 1998-12-17
Abstract: For determining the operating point of a non-linear amplifier (2) of a commmunication channel (1), for example of a transponder in a communication satellite, a first input signal (I1) is transmitted through the communication channel (1) at a power level (PI1) which drives the non-linear amplifier (2) in a non-linear operation mode. In addition, a second input signal (i2) is transmitted through the communication channel (1) simultaneously with the first input signal (h). The second input signal (i2) is transmitted at a level below the level of the first input signal (I1). If the contribution of the second input signal (i2) to the total input of the non-linear amplifier is small, the operating point of the non-linear amplifier is determined almost only by the first input signal. Therefore, the output power (P02) corresponding to the second signal (i2) is determined most strongly by the input power (PI1) of the first signal (I1). The operating point (I1, P0) of said non-linear amplifier (2) is determined on the basis of an output signal (02) of said communication channel (1) corresponding to said second signal (i2).
