Patent CA-2109191-A1 (CA)
Title: Automatic Network Element Identity Information Registration Apparatus and Method
Inventor: HUNT CHRISTOPHER J
IPC: H04Q3/00
Filed: 1993-10-25
Abstract: In a telecommunications management network including a network element provisioned as a so-called Directory Services Network Element (DSNE) and at least one sub-network intended to include one or more network elements, automatic registration network element identity information is realized by employing a routing exchange protocol to dynamically maintain identity information of network elements reachable within the network, enhancing the routing exchange protocol interface to automatically supply an indication of detection of a newly reachable network element to an applications layer protocol, and using the indentity information of a newly reachable network element in the applications layer protocol of the DSNE to establish communications with the newly reachable network element. Then, the newly reachable network element supplies additional identity information (e.g., its name, network address and the like) to the DSNE. The DSNE, upon receiving the additional identity information, supplies its identity information to the newly reachable network element. Consequently, the identity information of the DSNE is supplied to each newly reachable network element as it is added to the network. This provides all network elements the capability of establishing communications with the DSNE, so that queries can be made for identity information of other network elements in the sub-network. The retrieved identity information can, in turn, be used by the individual network elements to establish communications with other network elements in the sub-network. (FIG.1)

Patent CA-2116081-A1 (CA)
Inventor: MCCORMACK ANN L
IPC: C08J5/18
Filed: 1994-02-21
Abstract: Disclosed herein is a breathable film and a breathable, cloth-like film/nonwoven composite made from the breathable film which is stretch-thinned and bonded to a fibrous polyolefin nonwoven web. Certain thermoplastic films such as, for example, linear low density polyethylene films are difficult to thermally bond to, for example, polypropylene nonwoven webs due to the incompatibility of the two polymers.      The present invention incorporates a bonding agent into one or both of the two layers thereby making it easier to thermally bond the two layers together. Processes for forming the various composite are also disclosed.

Title: Nozzle with self controlled oscillation
Inventor: SMITH LEARY W
IPC: B05B3/16
Filed: 1994-05-16
Abstract: A nozzle for providing an oscillating fluid stream has a stationary segment, and at least one oscillating segment pivoted to the stationary segment.  In one embodiment, the fluid stream impinges on an inwardly turned lip on the oscillating segment to drive the oscillation.  In other embodiments, the reaction of the fluid discharge assists in driving the oscillation of the nozzle, with or without assistance of the inwardly turned lip.  For high pressure systems, including the use of liquids, the segments may be more massive to redirect the fluid stream.  For compact systems, the plural segments may be completely housed within the stationary segment.

Title: Recording medium cassette
Inventor: SAWADA TAKASHI
IPC: G11B15/07
Filed: 1994-09-13
Abstract: A recording medium cassette comprises a cassette case cassette case board and a release part. The cassette case board has a plurality of board terminals and also has positioning holes formed in its outer surface so as to expose the plurality of board terminals along with insertion guide channels formed consecutively at the lower ends of the positioning holes so as to reach the lower end of the cassette case. Also, a release part slopes towards the lower end of the insertion guide channel away from the outer surface. The angle of the release part with respect to the height of the cassette case is greater than the angle of an inclined portion, which spans from contact points to free end parts of resilient connector contacts set up at a recording/playback apparatus connector, with respect to the height of the cassette case, and the connector contacts do not come into contact with the release part when the recording medium cassette is installed in the recording/playback apparatus and the contacts are therefore brought together in a reliable manner.

IPC: G01F15/04
Filed: 1994-02-28
Abstract: Peritoneal dialysis systems and methods move liquid using a pump chamber (P1, P2) that is operated in response to pneumatic pressure variations applied by a pump actuator (PA1, PA2). The systems and methods periodically measure air pressures in the actuator (PA1; PA2) and an associated reference air chamber (VS1, VS2) and derive from these a measurement of liquid volume moved through the pump chamber (P1, P2). The systems and methods minimize derivation errors by compensating for temperature differences among the pump chamber (P1, P2); the pump actuator (PA1, PA2); and the reference chamber (VS1, VS2).

Title: Blade assembly for a brush cutting machine
Inventor: DALLMAN JIMMIE J
IPC: A01D34/86
Filed: 1995-04-27
Abstract: A blade assembly for a brush cutting machine.  The blade assembly comprises two blades, each blade having a two sided cutting edge on both a first and second ends.  The four sided cutting edge blades are rotatable from the first end to the second end and invertible from the upper surface to the lower surface to take advantage of all four cutting edges on each blade.  A first blade is attached to the bottom surface of a first end of the crossbar.  A second blade is attached to the bottom surface of a second end of the crossbar.  The blades are attached to the bottom surface of the crossbar with counter-bored holes in the blades that correspond to counter-bored holes in the crossbar.  Counter-bored holes in the bottom surface of the blades recess the head of the attaching bolt so that the top of the head of the attaching bolt is flush with the bottom surface of the blades.  Counter-bored holes in the crossbar allow the attaching bolt to have a graduated diameter such that a large diameter bolt is used for a secure attachment of the blades to the crossbar, while allowing a small diameter bolt to receive a conventionally sized nut at the top of the crossbar.  The blades of the present blade assembly have a re-cuttable bevel to provide a resharpenable cutting edge. A second embodiment provides offsets on the crossbar for positioning the blades closer to the ground for a closer cut of brush.  A method for cutting brush with a brush cutting machine having the present blade assembly is also disclosed.
