IPC: A63B29/02
Filed: 2000-01-26
Abstract: Using a carabiner for securing rock climbing rope, it is known that the rope can only be removed from the carabiner by human hand. In this invention, an electric rope removal system is secured to the carabiner which pulls a pulley string that is attached to a rotating disk which is attached to an axle on the carabiner and removes the rope from the carabiner when the electric rope removal system is on. The electric rope removal system is governed by a timer. Another safety feature is the overall power of the electric rope removal system which can be adjusted to not remove the rope when the weight of a mountaineer is attached to the rope that is attached to the carabiner.              Repel - sliding down a rock climbing rope with a metal locking device. Carabiner - a piece of oval metal which holds a rock climbing rope into place with a movable safety gate to prevent the rope from leaving the carabiner. Mountaineer - a person that climbs(ascends) and descends a mountain or rock face (also known as a rock climber) Rock Face - a large vertical cliff on the side of mountain or hill.

Title: Paper stock screening apparatus and method
Inventor: VITORI CHRISTOPHER M
IPC: D21D5/02
Filed: 1998-08-06
Abstract: Pressure screening apparatus for screening a suspension of paper fiber stock employs a rotor (14, 15, 16) in which a single impulse or foil member (12) is carried or positioned to move along a discrete portion of the screen surface (10). This arrangement improves efficiency of operation of the pressure screen by reducing the rotational effect of the rotor (14, 15, 16) on the stock suspension being screened and by providing a less disturbed screening region through which the single foil (12) operates. Embodiments are shown in which a single foil (12) is combined, in screening apparatus, with multiple foils in accordance with the increase in consistency of the stock as it passes through the screen (10).

Abstract: A method and apparatus are provided for improved data transmissions on telephone links between service providers and remote clients. The method and apparatus perform the steps of receiving an analog encoded data signal and performing a high precision, synchronized analog to digital conversion while the signal is relatively close to a phone company central office switch assembly. The signal is transferred to output circuitry used to transmit signals on phone company subscriber lines. The signal is converted back to an analog signal prior to its final transmission to a subscriber client modem. In an embodiment of the invention, the high precision, synchronized analog to digital conversion is performed by a client-type modem and the output is transferred to a server-type modem which transmits the converted signal, in digital form, over a pair gain system. In an alternative embodiment, the client-type modem resides on the central office terminal side of a pair gain system and the server-type modem resides on the remote terminal side of the pair gain system.

Patent CA-2308880-A1 (CA)
Inventor: ZUGRAVU LIVIU
IPC: G01G19/08
Filed: 2000-05-19
Abstract: Sometimes we need to be sure that the maximum allowable load of a vehicle has not been exceeded, or that the load is between permitted limits. Sometimes we want to be sure that the weight of a vehicle has not been altered while unattended; differences in load show us that either a weight has been added (a bomb in case of a terrorist attack), or that weight has been removed (possible theft). This invention creates the passibility to measure/monitor the differences in the vehicle weight and/or measure the vehicle weight without using a scales. The device employs sensors whose signals are analysed by a microprocessor and the result is displayed on a portable remote unit which is carried by the authorised person.

Abstract: L'invention concerne un système pour varier l'écartement de voies (1) d'un train à sustentation magnétique. Les voies (1) sont formées par des supports de voies (4), qui sont placés les uns à la suite des autres et sont interconnectables. Afin de créer cette jonction de voies, dans chaque voie, un support de voie (4) se présente sous forme de support flexible (5), pouvant être sollicité en flexion pour créer la jonction entre les voies (1). A l'état cintré, chaque support flexible (5) peut être positionné par rapport à l'autre support flexible (5). Dans chaque voie, un support de raccordement (6) est disposé de manière adjacente au support flexible (5). Afin de créer, pour le passage du train sur la jonction de voies formée à partir des supports flexibles (5), un écart nécessaire par rapport à la jonction de voies, le support de raccordement (6) peut être déplacé hors du profil d'espace libre du véhicule. L'invention se caractérise en ce que pour créer une seconde jonction de voies, les supports de raccordement peuvent être sollicités en flexion et que les supports flexibles (5) peuvent être déplacés hors du profil d'espace libre du véhicule au moment de la formation de la jonction de voies réalisée à partir des supports de raccordement (6).

IPC: E21B17/042
Filed: 1999-03-10
Abstract: A threaded pipe connection is disclosed that includes a box member (112) and a pin member (111). The box member (112) has a tapered, internal, generally dovetail-shaped thread (114) incorporated in a two-step wedge configuration such that there exists a smaller step and a larger step each with stab flanks, load flanks, roots, and crests. The internal thread (114) has a beginning and an end and increases in width in one direction. The pin member (111) also has a tapered, external, generally dovetail-shaped thread (115) incorporated in a two-step wedge configuration such that there exists a smaller step and a larger step each with stab flanks load flanks, roots, and crests. The external thread (115) increases in width in the other direction so that the complementary flanks of the respective threads move into engagement during rotational make-up of the connection and form sealing surfaces that resist the flow of fluids between the threads on the smaller step of the box member (112) and the smaller step of the pin member (111) upon rotational make-up of the connection, while leaving clearance between the threads on the larger step of the box member and the larger step of the pin member upon rotational make-up of the connection.

Abstract: A polymerization method characterized by conducting the atomic-transfer radical polymerization of a vinyl monomer so as to satisfy at least one requirement selected from the group consisting of the following (1), (2), (3), and (4): (1) the polymerization is conducted under substantially dehydrating conditions; (2) the polymerization is conducted in the presence of a nitrile compound; (3) the polymerization is initiated by adding a ligand for a polymerization catalyst to the system; and (4) the rate of polymerization is controlled by changing the activity of the polymerization catalyst during polymerization. Thus, an easy and safe method for initiating the atomic-transfer radical polymerization and a method for controlling the polymerization rate are provided which are effective in enabling a large proportion of terminal halogen-containing groups to remain and in eliminating problems such as the difficult control of polymerization rate due to catalyst sedimentation or a change in catalyst amount. Improvements in the polymerization are suggested.
