Title: Frequency Plan for a Cellular Network
Inventor: FARUQUE SALEH
IPC: H04B7/26
Filed: 1994-06-15
Abstract: An N=3 frequency plan for 60 degree sector transmit sector receive (STSR) cell sites is based upon dividing avail-able channels into 18 frequency groups. Frequency assign-ment is in accordance with an odd-even cyclic distribution of channels which provides a three-channel separation between sectors within a cell and an eight-channel separation between cells. This ensures adequate channel isolation between sec-tors and improved adjacent channel C/I performance through-out the network.  The N=3 frequency plan increases chan-nel capacity by approximately 38 % in AMPS and 114 % in TDMA-3.

Patent CA-2186557-A1 (CA)
Inventor: BURMASTER BRIAN M
IPC: F28D7/00
Filed: 1996-09-26
Abstract: An improved shell and tube heat exchanger for transferring heat energy between two fluids is provided. The heat exchanger design is characterized by double-segmental baffle geometry in which the tubes within the shell do not pass through the "windows " or passageways defined by the baffles for the flow of the shellside fluid through the shell. The absence of tubes from the shellside fluid flow passageways reduces the nonideal nature of the shellside fluid flow such that the shellside heat transfer coefficient is increased and the required shellside heat transfer surface area is decreased. The heat exchangers of the present invention are particularly suited for acid coolers used in contact sulfuric acid plants which typically have a large heat transfer surface area requirement and a shellside heat transfer coefficient significantly lower than the tubeside heat transfer coefficient. In such applications, the new design may eliminate the need for multiple shells. If necessary, tube support plates can be added to eliminate potential tube vibration without negatively impacting the shellside flow or heat transfer.

Patent CA-2191814-A1 (CA)
Inventor: TIHON CLAUDE
IPC: A61M25/00
Filed: 1996-12-02
Abstract: An  urethral  drain  having  deep  external  drainage channels, a low-profiled bladder retention segment, and a reversibly detachable collection segment, facilitates the draining of urine and fluids from the bladder.  The low-profiled retention means minimizes bladder irritations and the  deep  external channels  reduce  the  occurrence  of infections.   Incorporation of a reduced diameter smooth segment on the catheter, proximate the location of the external urethral sphincter allows the patient to void normally and at will.  Modifying the size of this smooth segment aids the function of a defective sphincter in controlling urine leakage.  The drain can be worn concealed within the urethra.  Flushing action from normal voiding washes out particulate matters in the urethra and the concealed drain further minimizes contamination.  Together, these features improve quality of life for patients needing catheterization.

Patent CA-2202968-A1 (CA)
Inventor: BROWN ALAN J
IPC: D21H17/68
Filed: 1997-04-17
Abstract: A process is provided for the selective aggregation of the fine and ultrafine particles present in an anionically or cationically dispersed mineral pigment slurry, such that an aggregated structure is formed which contains within it a labyrinth of internal voids or pores, which collectively function as light scattering centers. The aggregates are formed from an assemblage of fine mineral particles, interconnected or bonded together with small quantities of a cationic or anionic polymer or agent of low molecular weight. The resultant aggregates are of larger mean particle size than the feed material and contain little or no fine and colloidal particles. The net charge present on the aggregated particles is lower than that of the feed material. These mineral aggregates are then of a suitable size and surface charge to be retained well in a fiber web by a combination of filtration retention and adsorption retention, and provide added bulk and opacity to the finished sheet of paper. The high solids, aggregated, products of this invention can also be used to enhance the optical properties, smoothness, printing properties and surface coverage of coated paper and paper board.
