Title: Human power amplifier for lifting load including apparatus for preventing slack in lifting cable
Inventor: KAZEROONI HOMAYOON
IPC: B66C1/02
Filed: 2000-02-17
Abstract: A human power amplifier assist device (10) includes an end-effector (14) that is grasped by a human operator and applied to a load (25). The end-effector (14) is suspended, via a line (13), from a take-up pulley (11), winch or drum that is driven by an actuator (12) to lift or lower the load (25). The end-effector (14) includes a force sensor (31) that measures the vertical force imposed on the end-effector (14) by the operator and delivers a signal to a controller (20). The controller (20) and actuator (12) are structured in such a way that a predetermined percentage of the force necessary to lift or lower the load (25) is applied by the actuator (12), with the remaining force being supplied by the operator. The load (25) thus feels lighter to the operator, but the operator does not lose the sense of lifting against both the gravitation and inertial forces originating in the load (25).
Patent CA-2373388-A1 (CA)
Inventor: GADBERRY DONALD L
IPC: A61B17/122
Filed: 2000-06-05
Abstract: A surgical spring clip includes two molded components, each having a jaw and a finger tab. The first component has a telescoping relationship with the second component and is moveable by operation of the finger tab between a first position wherein the jaws are generally open. A spring disposed between the tabs and the jaw biases the first and the second components toward the first position. The clip has a telescoping barrel with the general shape of a polygon in radial cross-section. An increased guidance link provides the clip with a guidance ratio of about 1.5 ratio.  Alignment of the components is further enhanced by the provision of ramped projections and the accomodation of tolerances only along one side of the telescoping barrel. A  simplified method of assembly requires movement of the second component through a window in the first component.

Title: System for the oxygen delignification of pulp consisting of lignocellulose-containing material
Inventor: RAGNAR MARTIN
IPC: D21C9/10
Filed: 2000-07-06
Abstract: The invention relates to a system for the oxygen delignification, in at least two reaction stages, of pulp which consists of lignocellulose-containing material and whose mean concentration is 8-18%  pulp consistency. The oxygen delignification takes place in a first reaction stage (6) in which an essentially constant and low pressure prevails during the whole of the delignification process, after which the second delignification stage (10), with a substantially higher pressure and temperature and a longer dwell time, begins. The invention is characterised in that the first reaction stage (6) consists of a pipe loop arranged to lie essentially in the same horizontal plane.

Abstract: Methods and apparatus for secure over-the-air (OTA) programming, and particularly, activation, of a wireless unit in a particular communications system. The unit stores a stored key having been generated by using a key algorithm (K-algorithm) with an identifier associated with the unit as an input to the K-algorithm. The unit may receive information such as parameters and a verification number from a communications system for the purpose of programming the unit. The verification number is generated by using an authorization algorithm (A-algorithm) having the parameters and a key as A-algorithm inputs. The key is generated by the K-algorithm having the identifier associated with the as K-algorithm input. In response to receipt of the parameters and the verification number, the wireless unit generates a trial verification number by using the A-algorithm with the parameters and the stored key as trial inputs. The unit compares the verification number to the trial verification number for a match. When finding the match, the unit uses the parameters for programming of the unit in the particular communications system. When failing to find the match, the unit fails to use the parameters for the programming.

Title: Traffic control unit and traffic control method
Inventor: KAWAKAMI HIROSHI
IPC: H04Q11/04
Filed: 1999-03-05
Abstract: A traffic control unit and a traffic control method are provided. They carry out, in a first shared resource (like a radio base station in a mobile radio network) of a network including besides the first shared resource, a second shared resource (like a transmission path between a radio base station and a local switch) and a local switch, which are shared by a plurality of users, traffic control of data to be transmitted to the local switch through the second shared resource. This makes it possible to positively achieve the traffic control, and to prevent the shared resources in the network from being wasted.      Appropriate control is implemented by carrying out, for data taking place in a burst mode at a period proper to the data, traffic control such that a cumulative transmission volume in a traffic monitoring period determined by taking account of the proper period does not exceed an allowed transmission volume based on a traffic rate.

Title: Blowout preventer packing element with non - metallic composite inserts
Inventor: BORDEN KELLY
IPC: E21B33/06
Filed: 2003-02-13
Abstract: A packing element for a blowout preventer includes an annular flexible non-metallic composite body disposed about a longitudinal axis that is adapted to be compressively displaced inwardly towards the axis. A plurality of non-metallic composite inserts are embedded in the body in generally circular fashion spaced apart in respective radial planes extending form the axis for reinforcing the body. Each of the inserts includes upper and lower flanges, and a web element extending between the flanges. The web element includes trailing and leading edges, each having outer arcuate surface that are substantially semicircular in cross-section for distributing the loads applied to a bond line between the insert and the flexible nor-metallic composite body during the operation of the packing element. A central rib extends between the leading and trailing edges. The shape of the web element increases the volume of the flexible non-metallic composite body and reduces the loads applied to the bond line, substantially increasing the life of the blowout preventer. The replacement of metal inserts with non-metallic composite inserts eliminates sparks and scoring of string, which leads to explosions.
