Title: Methods and apparatuses for fast power control of signals transmitted on a multiple access channel
Inventor: HOWARD STEVEN J
IPC: H04B7/26
Filed: 1999-10-01
Abstract: A method and apparatus for controlling the transmission of signals from one or more of a plurality of mobile stations (1300) to a base station (1400) on a plurality of M multiple access channels. A power control information packet formed from a plurality of power control bits is transmitted from the base station (1400) to the one or more mobile stations (1300). Each of the power control bits in the power control information packet has a position that is mapped to a selected access channel and to a time offset within the selected  access channel. The power control information packet is received at a first mobile station (1300). A message is then transmitted from the first mobile station (1300) to the base station (1400) on a first access channel and at a  first time offset associated with the first access channel. The message is transmitted from the first mobile station (1300) at a power level determined  in response to a first power control bit in the power control information packet. The first power control bit is located in a first position in the power control information packet, the first position being mapped to the fir st access channel and the first time offset.

Title: Detecting obstructions in enteral/parenteral feeding tubes and automatic removal of clogs therefrom
Inventor: MANZIE PATRICK
IPC: F04B43/08
Filed: 1999-11-04
Abstract: A tube in a pumped fluid system can become obstructed by a clog. The clog is  automatically cleared in response to an obstruction signal (B) by modifying the pumping cycle which is normally used to pump the fluid. In particular, t he pumping cycle is stopped after a compression stroke (BDC'-TDC) to apply sustained high pressure in the clogged tube, using the same fluid and the sa me pump, to expel the clog from the tube. The obstruction signal (B) is derived  by measuring the pressure due to viscosity (C) effects have subsided. Therefore, if the pressure remains elevated, a determination of an obstructe d state can reliably be made which may be caused by a clog.

Patent CA-2350225-A1 (CA)
Inventor: COTNOIR DENIS
IPC: G01N15/02
Filed: 2001-06-19
Abstract: The invention relates to the determination of liberation and gravity separability in the fine particle size range by elutriation of narrowly screened size fractions in a centrifugal field using cyclonic devices. With this method it is possible to establish separation and grade/recovery curves for the separated particle size classes and thus indications of mineral liberation. For simple (e.g. binary) systems and known densities of the pure compounds it may be possible to construct these curves without using chemical assays if extremely narrow size classes are used and the separation system is well calibrated. The method is most suitable for applications that involve the use of little sample material and fast analysis.

Title: Coupling half and method of making same
Inventor: HARCOURT ROBERT
IPC: F16L37/24
Filed: 1999-06-21
Abstract: A coupling half for interconnecting fire hose or other hose to a reciprocal connection mounted on another hose or on a fixed object. The coupling half includes two slots (14, 42) which enable the manufacturing of the coupling half quickly, efficiently, and inexpensively. Only two molds (33, 34) are used to cast the coupling half compared with the traditional three molds. The molds (33, 34) are in contact with each other at three radial points with each radial point being separated by the mold cavity. Machining is greatly reduced as the coupling half is made from one piece as compared with the traditional two pieces. The slots (14, 42) in the locking collar enable the coupling half to be made of one piece resulting in less machining.
