Title: A t-shaped device optimizing tension and development of muscle hypertrophy
Inventor: LICASTRO FRANCO
IPC: A63B21/06
Filed: 2000-09-20
Abstract: When performing an exercise, a tension is exerted upon specific muscle. Two different types of tension can be realized when training. The first type of tension will come, with the use of barbells or dumbells, commonly known as free weights. The second source of tension is experienced with the use of a cable stack machine. This invention (Tensio Gravi-T) combines the two sources of resistances to optimize the concentric phase of the desired movement and simultaneously benefiting from higher muscle fiber recruitment.

Patent CA-2326060-A1 (CA)
Inventor: CRAIG PETER MATHIESON
IPC: H01R43/26
Filed: 2000-11-15
Abstract: There is provided, in combination, male and female cooperating teledapt connectors located in a recess with respect to a mounting surface s o as to minimize electrostatic discharge between an operator's hand and the connectors, wherein the male connector has a main body from which a tongue projects, and  the female connector defines a groove in which the tongue is adapted to lie. The  tongue has shoulders which, when the connectors are put together, come into contact  with abutments formed in the female connector, such contact preventing release of  the connectors until pressure is exerted to move the tongue toward the main body  and thus to break contact between the shoulders and the abutments. The key to achieving this is the provision of an actuator having an attachment portion and an operative portion, the attachment portion being adapted to mount the operati ve portion so that the operative portion extends adjacent the tongue and projec ts out of the recess far enough to be manipulated so as to move the tongue toward said  main body far enough to break contact between the shoulder means and the abutment means.

Title: Assembly comprising pump rod and threaded union
Inventor: VILLASANTE JOSE
IPC: F16L15/00
Filed: 2000-11-30
Abstract: An assembly comprising a pump rod and a threaded union of easy assemblage and capable of transmitting high torque. The pump rod, having a hollow body, activates rotary-type pumps. The motion that activates the pump is, in this case, produced by rotary movement by means of the application of a rotation moment or torque. The type of rod presently used and that this invention replaces for use in rotary pumping is under the API 11B Norm. One distinctive characteristic is the type of special threaded union that is used for coupling of the different rods. This union includes a nipple or threaded member in its outside surface in its two extremes called male - that are coupled respectively with a pair of members, each one of them threaded in its internal surface - called female. The union between the male and the female extremes is accomplished by means of the threaded surface of such extremes. Other characteristic of the assembly hollow rod - threaded union is greater resistance to uncoupling by counterrotation turn of the column of rods or "backspin".

Patent CA-2331248-A1 (CA)
Title: Anti-decoupling arrangement for an electrical connector
Inventor: FREAR DAVID LEIGH
IPC: H01R13/622
Filed: 2001-01-17
Abstract: An anti-decoupling arrangement for an electrical connector (as well as an electrical connector incorporating such an anti-decoupling arrangement) is made up of just three operative components: a spiral lock clutch , at least one spring ring, and ratchet teeth or serrations formed on an inside surface of the coupling nut. The ratchet teeth are in the form of serrations formed into the inside diameter of a recessed area of the coupling nut in which all of the components reside, and each spring ring is a self-supporting ring that has spring cantilevers with engaging tines of a given number located around its outer circumference, the engaging tines engaging the serrations in a radial direction. The engaging tines thus provide a torque/ratchet mechanism when they glide over the radial cuts of the tooth ring in the uncoupling direction, and stay engaged which forces the spiral lock clutch to expand and slide smoothly over the plug shell with minimal torque in the coupling direction.

Filed: 1999-09-21
Abstract: A long haul, broadband DWDM system that has been optimized by the proper selection of the distribution of total dispersion compensation. Dispersion compensation is utilized at both the receiver and the transmitter ends. System performance is dependent on the ratio of compensation split between the transmitter and the receiver. A system operated in the non-linear regime can be compensated to operate with low BER and with reduced penalties due to residual dispersion effects, even when the spread of the total accumulated dispersion between the extreme channels in a broadband system exceeds 1,000 ps/nm.
