Abstract: An axially extending tubular composite member (100) having a plurality of plies and extending along a longitudinal axis has at least three plies (116, 118, 120) with selectively structured fiber components in each ply. Typically an inner ply (116) has at least one biaxial fiber component, an intermediate ply (118) has at least an axial fiber component that typically is combined with two further fibers to form a triaxial fiber component. Another ply (120) typically has a woven fiber component. A further ply having a biaxial component either replaces the ply of woven fiber or is disposed beneath it over the intermediate ply. A surface veil (122) having fiber and an excess of resin material typically covers at least the innermost or outermost surface of the composite member. An internal web member (112, 114) can be provided, and typically also employs fibers and the matrix material.
Patent CA-2227296-A1 (CA)
Inventor: FLEMING JANET E
IPC: A61N1/32
Filed: 1996-10-03
Abstract: A system (10) generates bio-active frequencies having a precision of 0.001 Hz for health science applications. A micro-controller (16) instructs a frequency synthesizer (12) to generate specific precise frequency signals. A user may select a specific frequency, a sequence of frequencies, or a preprogrammed series of frequencies using a keyboard (18). Alternatively, an automatic frequency selector (21) may scan the patient and automatically select appropriate frequencies for generation. Depending upon the specific frequency being generated, the system (10) gates signal ON or OFF for predetermined periods of time. A sound circuit (36) generates an auditory warning prior to signal generation. A soft start circuit (34) gradually increases the frequency of the signal at a predetermined rate from zero to a predetermined user controlled level. A display (20) indicates information representative of the specific frequencies selected and their durations. An indicator (not shown) informs the user whether the device's application electrodes (24) are in proper contact with the patient.

Patent CA-2238581-A1 (CA)
Inventor: EL-MAMOUNI RACHID
IPC: C02F3/28
Filed: 1998-05-22
Abstract: The invention disclosed relates to a method for enhancing the granulation rate of suspended anaerobic sludge. The method comprises the incremental additions to the sludge over a period of time of a cationic synthetic e.g.  polyacrylamide polymer or a natural e.g. chitosan polymer. The method was performed in laboratory-scale upflow anaerobic sludge bed (UASB)-like reactors operated under similar conditions over a period of 5 weeks. A total of 4 injections was carried out, during the entire course of this study. The results showed that supplementation of the reactors with polymers, either the natural or the synthetic, enhanced the granulation compared to that in the control reactors (without the use of polymers). The polymers did not cause any inhibition to biomass activity. Furthermore, the granules specific activities were enhanced in the reactors supplemented with both polymers compared to those in the control reactors.

Patent CA-2262342-A1 (CA)
Inventor: COOMBS JOHN DOUGLAS
IPC: B67B7/78
Filed: 1999-02-09
Abstract: Unlike conventional manual can openers which use a single shear cutter and a turning apparatus to either shear the can lid open or to shear the can lid off by moving around the circumference of the can, the Can Wizard Manual Can Opener is an innovative new idea which cuts the can lid off just below the lid using three shear cutters spaced 120 degrees apart. The Can Wizard Can Opener uses no turning knob apparatus but instead uses three L-shaped handles, attached independently to three cutters on a circular base plate. When pressure is applied to the handles the cutters shear the can when the can is turned on the base plate
Patent CA-2263280-A1 (CA)
Title: Method and apparatus for mobile satellite communication
Inventor: CHRISTODOULIDES LOUIS
IPC: H04B7/216
Filed: 1999-03-02
Abstract: A set of formats and protocols is proposed for a satellite communications system. In these formats, a pilot signal (PS) is inserted after every 25 or 29 data symbols. The formats consist of SCPC frames (F) which may contain either data (D) and in-band signalling information (SU), or only signalling information (SU). In either case, the contents of each frame (F) are error-correction coded before transmission with the same coding rate. Each data frame (F) carries the data content of an integral number of input user data frames (M), each of which comprises four subframes. Different symbol transmission rates are used for different input data rates, the symbol transmission rates being selected so that their different synchronising clock rates can easily be obtained from a common clock. Data bursts may be preceded by a constant power level preamble (P). The formats and protocols satisfy the requirements of a high data rate satellite communications system.
