Patent CA-2193857-A1 (CA)
Title: Fluid circulation pipe
Inventor: MATIERE MARCEL
IPC: F16L1/028
Filed: 1995-06-28
Abstract: A pipe for circulating pressurized fluid comprises a tubular enclosure (1) with a thin wall (1) secured to a rigid support slab (2) of a moulded material. According to the invention, the upper part (12) of the enclosure (1) consists of, as seen in cross section, at least three lateral thin wall segments, two lateral segments (3, 3') each extending between a lower side (31) and an upper side (32) and at least one enclosure-closing upper segment (4) connected to the upper sides (32, 32') of the lateral segments (3, 3'). Each lateral thin wall segment (3, 3') is associated with a rigid support element (5, 5') of a moulded material secured at its base to the corresponding side of the slab (2) and comprises an inner face (51, 51') oriented towards the enclosure (1) having a profile matching with that of the lateral segment and on which the latter is applied. The inner face (51, 51') extends from the level of the upper face (23) of the slab (2) up to a level (H2) sufficient to maintain the rigidity of the lateral segment along all its height (H1) so as to prevent flattening.

Patent CA-2194882-A1 (CA)
Inventor: ROY BRIAN P
IPC: F01N13/14
Filed: 1995-06-29
Abstract: A process is disclosed which leads to a substantial improvement in the efficiency of bleaching lignocellulosic and like materials with hydrogen peroxide. This has been achieved by reducing the rate and extent of non-productive decomposition of peroxide. The bleaching of lignocellulosic materials at increased temperatures and pressures accelerates the rate of pulp bleaching and the rate of peroxide decomposition. Conventional bleaching technology limits these non-productive reactions by including silicates or chelating agents in the bleaching solution. Here it is shown that a substantial part of the peroxide decomposition that occurs upon exposure to process equipment is decreased substantially by using an appropriate metallurgy. A bleaching vessel having at least a contact surface, i.e., a surface in contact with the processed pulp, constructed from zirconium, niobium, hafnium, tantalum or alloys thereof is described which limits peroxide decomposition. The use of zirconium, niobium, hafnium, tatalum or alloy thereof eliminates the requirement for silicate and other sequestering agents in the bleaching solution. This novel bleaching technology is used to improve the efficiency of alkaline peroxide with both conventional as well as with new high temperature lignocellulosic bleaching processes or processes which generate peroxide species under alkaline conditions.

Patent CA-2196216-A1 (CA)
Title: Reduced power selective excitation rf pulses
Inventor: SHINNAR MEIR
IPC: G01R33/483
Filed: 1995-07-26
Abstract: A method far limiting the peak power and total energy of an input pulse without degrading the resulting excitation. This is accomplished by recognizing that the total energy of the pulse is encoded in the lowest order Fourier series coefficients of the frequency response and then specifying the total energy of the pulse as a design parameter to the RF pulse synthesis algorithm.  Peak power of the pulse may also be limited by selecting the proper roots for the frequency response describing the magnetization in the z-direction.

Title: System and method for identifying the technique used for far-end performance monitoring of a ds1 at a customer service unit
Inventor: TRAN MINH
IPC: H04Q3/00
Filed: 1997-06-25
Abstract: Described herein are a system and method of determining a far-end format of a customer service unit (CSU) operating using an Extended SuperFrame (ESF) framing format. The CSU is in communication with a network element over a DS1 circuit.  The system operates by determining whether any performance data was received from the CSU during a preceding time interval. If no performance data was received from the CSU during the preceding time interval, then the system determines whether the network element is currently configured to operate according to ANSI standard T1.403 or AT&T Recommendation 54016.  If the network element is currently configured to operate according to AT&T       Recommendation 54016, then the system commands the network element to operate according to ANSI standard T1.403.  The system then waits a predetermined time period for receipt of valid performance data conforming to ANSI standard T1.403 from the CSU. If valid performance data conforming to ANSI standard T1.403 is received from the CSU during the predetermined time period, then the system commands the network element to operate according to ANSI standard T1.403  until further notice. If valid performance data conforming to ANSI standard T1.403 is not received from the CSU during the predetermined time period, then the system commands the network element to return to operating according to AT&T Recommendations 54016.

Filed: 1996-02-09
Abstract: During the mixing of an unhomogeneous flowable material in a tank (2) provided with mixing blades (4), the properties of samples taken from the material in the tank are measured and recorded. The material is removed from the tank through a tube (10) placed close to the tank, said tube having an opening communicating with the internal space of the tank, and material being removed is conveyed into a measuring segment (10b) by means of a conveying member (18) placed in the tube. Then, the effect of the material present in said tube segment (10b) on electromagnetic energy being transmitted into the tube (10) is measured. The measuring procedure that comprises the introduction of fully or partly new material in the tube segment (10b) and subsequent measurement is repeated once or a number of times, and the individual measuring values or sets of such from the individual measuring procedures are recorded. The material being present in the tube segment (10b) during a measuring operation may constitute a quantity that is not representative for the determination of one or a number of components of the material in the tank (2) on the basis of one single recorded measurement value or one single set of same, and if so, the content of one or a number of components of the material in the tank is determined by repeating the measuring procedure so many times with new material being introduced into the tube segment (10b) that the sum total of the quantities of material being measured in the tube segment constitutes a representative quantity. Then, the content is computed on the basis of the recorded measurement values or sets of same.

Title: System and method for contraband detection using nuclear quadrupole resonance
Inventor: MOELLER CHARLES R
IPC: G01N24/00
Filed: 1996-03-05
Abstract: A system for detecting a target substance within a class of explosives and narcotics containing quadrupolar nuclei through the use of nuclear quadrupole resonance (NQR). The system applies an RF signal to a coil (34) to excite the substance under test. If the target material is present, an NQR signal will be picked up by the same coil.  That signal is compared with known NQR signals in frequency and amplitude. A  signal is displayed in an appropriate way if a threshold value of the NQR signal is equalled or exceeded. The empty coil is statically tuned by means of adjusting the location or capacitance values, or both, of static tuning capacitors (102) in the coil.  The coil is tuned after the specimen is inserted into the coil by means of an auto-tune feature (36).  Effective RFI shielding (37) is provided to prevent external contaminating signals from being detected by the coil and to prevent RF signals from escaping from the scanner.  The invention also includes the method for performing tests with the system.

Abstract: A syringe for dosed injection of a medicine from an exchangeable cartridge has a housing comprising a cartridge holder and a dosing mechanism by which a dose is set and subsequently injected by successively advancing a piston rod to press a piston into the cartridge.  The dosing mechanism comprises a threaded spindle and a nut member co-operating with the spindle. A dose is set by relative rotation of the spindle and nut member whereby the nut member is moved along the spindle.  The position of the nut member on the spindle defines how far the piston rod is advanced. The spindle and the nut is locked against relative rotation when the dosing mechanism is not operated to set a dose. Access to the cartridge holder is obtained by opening a lid connected to the housing and coupled to the dosing mechanism in such a way that the locking of the nut element in its position on the spindle is released when the lid is opened, and the opening movement of the lid is transmitted to a piston rod retraction mechanism.
