Title: Adjustable leash controlled strain reducing animal harness
Inventor: KIRCHER PAUL J
IPC: A01K27/00
Filed: 2000-12-15
Abstract: An animal harness is formed from a length of rope and includes a leash loop closed with a first rope locking mechanism, a top connecting line which terminates at a second rope locking mechanism. a shoulder loop, and a bottom connecting line which terminates at another rope locking mechanism. A girth loop is included in the animal harness. A method of restraining an animal includes placing the animal harness on the animal such that the girth loop encompasses the animal's torso just behind the chest of the animal. The animal's head is placed through the shoulder loop and the leash loop and a leash is attached to the leash loop. When the leash is pulled, the girth loop tightens around the abdomen of the animal which produces an instinctive submissive response and the animal ceases to pull against the leash.

Title: Composite trunking
Inventor: DENNISON LARRY R
IPC: H04L12/56
Filed: 1999-04-15
Abstract: An Internet router treats plural output ports with a common destination as a composite port. A routing table uses the IP address to determine a composite trunk to which the packet is to be forwarded. A forwarding table identifies a route along a routing fabric within the router to a specific output port of the composite port. Output ports and fabric routes are selected to maintain order within a flow by routing the flow along a single fabric route to a single output trunk. The forwarding table may favor output ports which are nearest to a packet input port, and the forwarding table may be modified to dynamically balance load across the trunks of a composite trunk.
Patent CA-2330470-A1 (CA)
Title: High temperature bolting system
Inventor: STEINBOCK ROLF H
IPC: F01D25/24
Filed: 1999-04-28
Abstract: A high temperature bolting system for clamping steam turbine housings and similar high temperature parts together while operating at a temperature of 800 °F to 1200 °F. An elongated fastener shank and housing material have similar coefficient of thermal expansion. The shank has a tensile strength several times greater than the housing to maintain a clamping force during thermal excursions. The diameter of the shank is reduced due to the large creep strength difference between the elongated fastener shank and the clamped parts. The reduced shank diameter allows an increase in the clamping load by providing an increased surface area in the clamped part. A stress generating flange is provided with jackbolts to establish the clamping load at room temperature. A threaded sleeve is interposed between the threads at the end of the shank and the threads of the housing so that the housing threads have a sufficiently large area for withstanding the clamping load. A truncated conical internal wall in the shank in combination with a differential thread pitch in an embodiment provides higher resistance to the clamping force. A flanged support ring is mounted at a bolt hole in the flange to support a load bearing area when retrofitting existing housings.

Title: Control system, display, host computer for control, and data transmitting method
Inventor: SHINOHARA AKIO
IPC: G05B11/01
Filed: 1999-04-23
Abstract: A display (3), conventionally used for only displaying a control state of a control unit (2), is used as a main unit for data communication, and performs conversion of the communication protocol governing data communication between control units (2) or between a control unit (2) and a data processor (7). Therefore the control units interlockingly operated in a control system (1) can be used exclusively for I/O control which the control units (2) primarily perform, thereby lightening the burden on the control units (2). Though there are a large number of types of communication protocol, it is unnecessary to take into consideration the type of communication protocol governing control units (2) and data processor (7), and the man-hours taken to write a software is reduced.

Title: Hypodermic syringe with selectively retractable needle
Inventor: COHN SIMON
IPC: A61M5/50
Filed: 2001-08-07
Abstract: A retractable needle syringe includes a barrel defining a receiver. There is a plunger having an inner rod extending distally from the proximal end. The plunger includes a hollow sleeve that is disposed over and extend beyond an inner rod.  The plunger includes a hollow cutter extending from the inner rod and a stopper disposed over the end of the sleeve. The plunger has a displaceable collar to prevent movement of the inner rod with respect to the sleeve, that is by distal force to the plunger by engagement with the proximal end of the barrel allowing the cutting surface to cut through the stopper. There is a hub with a stem, a proximal flange and an engagement. A  clip having a proximal foot with an opening therethrough and a distal grip is disposed on the stem of the hub. The proximal foot of the clip is disposed at the distal surface of the flange and the grip at the engagement on the stem. There is a spring disposed about the stem compressed between the receiver and the clip to provide a bias, so that when sufficient force is applied to the plunger causing the cutting surface to cut through the stopper, the cutting surface then engages, cuts through the flange to engage the clip and cause the clip to release the engagement on the stem. This allows the spring to urge the hub to a position within the syringe.
