Patent CA-2241988-A1 (CA)
Title: Method, telecommunication system, and processor device
Inventor: WELLMANN HANS
IPC: H04M3/42
Filed: 1998-08-04
Abstract: Known methods and systems for providing telecommunication services to a user, like number portability, are based on Intelligent Networks, of which the installation is expensive and time-consuming. These networks can be avoided in case a mobile switch is coupled via a processor device to a first database corresponding with a first network like GSM and to a second database corresponding with a second network like DECT and/or INTERNET, whereby an unused area code could be used to direct a call to said mobile switch, and interrogation of said databases takes place via said processor device. This results in the possibility of immediate providing number portability and routing into any network against low costs and without using Intelligent Networks.

Title: Multilayer sole attached to upper shoe reinforcement
Inventor: CRETINON FREDERIC
IPC: A43B7/14
Filed: 1998-06-22
Abstract: The boot (1) comprises a sole (2) made in three layers, namely a wear layer (3), a tendon layer (4) and a comfort layer (5). It also has a reinforcing part (20) which is cut out of the tendon layer. The reinforcing part has the shape of an arched band (20') contouring the region (34) corresponding to the malleolus of the user's foot. The reinforcing part is coupled to the tendon layer in a region (24) located between the heel (22) and the front end (23) of the sole. It extends freely on the edges (12,12') of the upper (10) into the rear region. The comfort layer is interposed between the user's foot and the tendon layer. The sole provides excellent lateral hold of the foot without interfering with the shock absorption of the comfort layer and leaves the heel free to flex.

Filed: 1997-08-07
Abstract: N-acetylcysteine, carboxymethylcysteine and thiazolidincarboxylic acid salts of erythromycin-2-propionate are produced by charging erythromycin-2-propionate and the sulphur-containing acid into a reactor. The reactants are homogenised and milled under nitrogen for 1 - 2 hours at 10 - 20 ~C. To this mixture purified water is added under nitrogen and the resultant aqueous mixture is further homogenised and milled for 1 to 2 hours at 10 - 30 ~C under nitrogen to produce a suspension of the desired salt. The suspension is dried under vacuum to produce a high yield of the desired salt at high levels of purity. Carboxymethylcysteine, N-acetylcysteine and thiazolidin-carboxylic acid salt of erythromycin, clarithromycin, roxithromycin and azithromycin may be produced in a similar manner.

IPC: G05B13/02
Filed: 1998-12-23
Abstract: A method and an apparatus for using fuzzy logic to determine when handovers are desirable and the extent to which the radio transmission power in a cellular telephone network should be adjusted. The mobile phone and the base transceiver station measure certain system parameters, including rate of handover, quality, distance, level, call duration, and power. These measurements are input to a fuzzifier. The fuzzifier applies standard fuzzy-set-theory membership functions to the measurements, and the fuzzifier outputs a set of fuzzy variables corresponding to the measurements. The fuzzifier outputs are input to an inference engine. The inference engine contains a set of rules that, when applied to the inference engine inputs, indicate: when a handover should be performed; when a handover should not be performed; and the amount by which, if any, the transmission power should be adjusted.

Title: Fill and pressurization apparatus
Inventor: MASON MURRAY R
IPC: B21D39/08
Filed: 1995-05-17
Abstract: Fill and pressurization apparatus having a sectional fluid conductor (27) having a first section (27a) fixed relative to the surroundings, and a second section (27b) which moves toward the first section (27) to form an enclosure (Fig. 2) through which a high volume flow rate low pressure flow may be passed to fill an adjacent open end of a tube (17) with liquid. Said fluid is passed through an inlet conduit (38), which may be a rigid conduit, to the fixed first section (27a). A seal head (77) insertable into the end of the filled tube (17) has an elastomeric seal member (87) and a rod (76) and a sleeve (78) relatively axially displaceable to compress the seal member (82) and deform it into sealing engagement with a surface of the tube (17). A stop member (84) on one of the rod (76) and sleeve (78) and a stop surface (81a) on the other of the rod (76) and sleeve (78) limit the axial displacement and hence also the compressive force applied to the seal member (82). The relative displacement is achieved by retracting one of the rod (76) and the sleeve (78) and blocking the retraction of the other. The blocking is provided by two telescoping cylinders (89 and 96), one (96) of which has abutments (99) thereon running in channels (101) provided in the other cylinder (89). To effect blocking one cylinder (96) is rotated relative to the other so that the abutments (99) are out of register with the channels (101) and engage stop surfaces (103) in an extended condition of the cylinders (89 and 96) relative to one another.

IPC: B21C37/08
Filed: 1999-12-03
Abstract: A weld bead chopper is provided, for use in combination with a scarfing tool which is intended to scarf a longitudinal weld bead from a tube. The chopper has a) a chopper blade which is rotatable about an axis which is substantially perpendicular to a longitudinal axis of the tube, and b) a stationary blade which is cooperable with the rotatable blade. The cooperating chopping surfaces of the rotatable and stationary blades are at a short distance from the weld bead, e.g. less than 100 mm, and preferably from 20 to 50 mm. The scarfed weld bead enters an enclosed throat which has walls to guide a scarfed weld bead towards the cooperating chopping surfaces. The throat has a first guide adjacent to the scarfing tool which directs the scarfed weld bead towards a second guide. The second guide faces the scarfing tool, and is adapted to guide the scarfed weld bead towards the cooperating chopping surfaces. The throat has a cross-sectional area substantially larger than the cross-sectional area of the scarfed weld bead. Additionally, the throat has a mouth which is sufficiently small to prevent the scarfed weld bead from exiting from the mouth.

Title: Spring trip standard having reduced spring buckling forces
Inventor: ZAUN RICHARD DAVID
IPC: A01B61/04
Filed: 2000-02-17
Abstract: A spring trip standard for a tillage implement includes a coil spring compressed between an upper spring-abutting surface on the mounting bracket and a lower spring abutment surface on a casting which is connected by a transverse pivot to the mounting bracket. The casting includes an integral stop extending forwardly from the pivot and contacting the bottom of the bracket when the shank is in the ground working position so that a tension link between the bracket and casting is eliminated. The casting includes a spring abutment surface having a first portion which extends generally perpendicular to the spring axis to support the lowermost end of the spring when the shank is stopped in the normal working position. The opposite side of the spring abutment surface is angled relative to the first portion, and the lowermost coil of the compressed spring, when the standard is in the tripped position, abuts the opposite side to maintain the spring in a non-buckling state. The lowermost coil is maintained generally perpendicular to the centerline of the coil spring in the field-working and tripped positions so that spring buckling and spring fatigue caused by buckling are reduced or eliminated.
