Abstract: Conventional coupling for a corrugated pipe have two retainers that engage between corrugations on the pipe. In the coupling of the present invention the retainers are hinged integrally with the coupling so that they can be folded down to project through apertures in the coupling and engage between corrugations on the pipe. When folded down in full engagement with the pipe, spring levers on opposite sides of the retainers engage under ledges in the aperture. The levers cannot engage when a retainer does not fully engage between the corrugations thereby making it apparent that the retainer is not fully engaged.

Title: Luminaire globe having low glare bandless seam
Inventor: SUBISAK GREGORY J
IPC: F21V17/10
Filed: 2003-02-12
Abstract: A bandless seam between reflector and refractor sections of a luminaire globe formed of light-transmissive material and configured to improve optical performance as well as facilitate effective mounting of the reflector and refractor sections together, the invention finds particular utility with suspended luminaires ordinarily requiring a metal band or the like to join said sections into a luminaire globe. Opposing peripheral edge surfaces of the reflector and refractor sections are shaped according to the invention not only to cause even flow of adhesive between said surfaces to adhere said sections to each other but also to reduce brightness at the resulting seam between the sections, thereby improving luminaire appearance and reducing seam brightness and optical glint.

Filed: 2001-08-02
Abstract: An electronically commutated direct current machine comprising a rotor and a stator has a stator winding arrangement that can be supplied, via a full bridge circuit (78), with current from a direct current source (73, 74). A commutation arrangement (49, 50, 52, 54) is provided for commutating the semiconductor switches (1) (80 through 85) and is embodied in order, as a function of at least the position of the rotor (110), in a first bridge arm to switch on only one semiconductor switch in each case, and in a second bridge arm, controlled by a switching signal (PWM2), alternatingly to switch on and off a semiconductor switch associated with the switched-on semiconductor switch of the first bridge arm. Also provided is an arrangement for generating a switching definition signal (PWM1) which, by way of its magnitude, controls the pulse duty factor for the alternating switching on and off of the semiconductor switch associated with the first bridge arm. Also present is a current limiting arrangement (131, 161), controllable by means of a current target value signal (PWM_I+; PWM_I-), which, when a current specified by the current target value signal is reached in the direct current machine, modifies the switching definition signal in such a way that the current in the direct current machine becomes no greater than a limiting current that is specified by the current target value signal.

Patent CA-2426017-A1 (CA)
Inventor: JEWITT DENNIS EDWARD
IPC: D21F7/12
Filed: 2001-12-12
Abstract: A device is provided for dewatering a fabric in which the fabric is used in a papermaking process that exposes it to water before it is directed to the fabric dewatering device. The fabric dewatering device includes leading and trailing guide rolls about which the fabric is partially wrapped to form a loop portion. The loop portion is suspended between the leading and trailing guide rolls and includes a trough portion with a relatively small diameter that is positioned below the axes of the guide rolls. Running the fabric through the trough portion at high speeds exposes the water trapped therein to high centrifugal forces. The centrifugal forces expel the water from the fabric. The geometry and positioning of the trough portion is maintained either through a difference in fabric speed maintained by the leading and trailing nips or by the use of a rider roll positioned within the loop. A non-contact sensor in proximity to the trough portion senses the position of the trough portion and provides feedback to a controller which controls the motion of the rolls.

Title: Method and apparatus for handoff of a wireless packet data services connection
Inventor: ABROL NISCHAL
IPC: H04L12/28
Filed: 2001-12-04
Abstract: A novel method and apparatus is disclosed for performing seamless handoff of  a mobile station (MS) between Radio Access Networks (RANs) that use different types of wireless interfaces. The described embodiments enable an MS to handoff between different RANs without causing routing ambiguity, and withou t substantial loss of network data. Upon moving from the coverage area of a first RAN using a first wireless interface to the coverage area of a second RAN using a second wireless interface, an MS determines whether routing ambiguity may result from the change of RAN and, based on the determination,  triggers a re-registration of its network address. A foreign agent (FA) with in a packet data serving node (PDSN) monitors network address re-registrations are being created for the same MS. Based on this determination, the PDSN terminates redundant R-P network connections resulting from movement of the MS between different RANs.

Title: Air-evacuable bag with double-layered valve film and method for manufacturing same
Inventor: ANDERSON BRENT
IPC: B31B19/84
Filed: 2003-06-18
Abstract: An air-evacuable bag has a one-way valve therein having two layers of valve film, neither of which is the sidewall of the bag. By forming the one-way valve of smooth, double- layered valve film, unwanted air gaps caused by textured surfaces in the sidewalls of the bag are avoided, thereby minimizing air leakage back into an evacuated bag. A method for the manufacture of such air-evacuable bags incorporates a roll supplying a first valve film layer, a roll supplying a first sidewall layer, a roil supplying a second valve film layer, and a roll supplying a second sidewall layer. As the film coming off the first valve film layer roll passes the roll supplying the first sidewall layer, both the sidewall layer and first valve film layer move in close proximity to one another until the valve film is tacked to the first sidewall layer. The second film and second sidewall layer are processed simultaneously in a like manner, and all four layers are joined at a sealing station.

Title: Defibrillation electrode cover
Inventor: KRALL ROBERT C
IPC: A61N1/05
Filed: 2002-04-25
Abstract: An implantable electrode provided with a thin, porous, wettable polymeric covering (30). The electrode covering of the present invention tightly conforms to the external profile of an electrode (24), which minimizes air gaps and voids. The electrode covering (30) is relatively thin, preferably less than 0.13 mm thick, and is treated to enhance rapid wetting by bodily fluids. The combination of minimal air gaps, tight conformance to the electrode, wettability and porosity of the thin covering, allows repeated, high energy electrical discharges to be transmitted without significant bubble formation, sparking or degradation of the covering. In addition, the electrode covering (30) of the present invention has pore sizes tailored to minimize cellular ingrowth and tissue attachment thereby allowing a less traumatic removal of the electrode after implantation if extraction becomes necessary, for example due to infection or electrode dislodgment.
