Title: Self-locking threaded connecting device
Inventor: VANDERDRIFT RICHARD W
IPC: F16B39/32
Filed: 1995-05-05
Abstract: A self-locking threaded connecting device comprising a male component (11) with a recess locking thread type (31) and a female component (12) with a flexible thread segment (21). Tension from the alignment of the internal flexible thread segment urges projections (22) of the flexible thread segment into the recesses (32) of the recess locking thread and thereby prevent the threaded fastener from loosening and coming apart in response to axial pressure optionally combined with vibration, expansion, contraction or other movement. The projections (22) and recesses (32) are shaped so that the faces glide by each other and unlock with the application of adequate torque. The two threads are designed to work together. The female component (12) when used with a standard male component (11) without recesses (32) provides resistance to inadvertent loosing.

Patent CA-2210816-A1 (CA)
Title: Network system and communication method
Inventor: NAKATA TORU
IPC: H04J14/02
Filed: 1997-07-18
Abstract: Disclosed is a network system for connecting a plurality of node devices by a plurality of parallel transmission channels and connecting terminals to respective ones of the plurality of transmission channels via the node devices. Each node device temporarily stores output packets by allotting the packets to a plurality of storage areas that correspond to respective ones of the plurality of transmission channels. When a stored packet is transmitted by selecting any one of the plurality of transmission channels, control is performed so as to read out the packet that has been stored in the storage area that corresponds to the selected transmission channel. In a case where a stored packet to be transmitted over the plurality of transmission channels is a packet for broadcast, the packet is duplicated by being distributed to the plurality of storage areas that correspond to the plurality of transmission channels that are to transmit the packet.

Patent CA-2214519-A1 (CA)
Inventor: BROWN CURTIS R
IPC: B05C9/14
Filed: 1996-03-08
Abstract: A method of forming a seamed metal tube (20c) having a metal coating (56) on at least an inside surface of the tube (20c) from a continuously moving, relatively flat metal strip (20a) is disclosed. The primary feature of the inventive process is the step, after forming and welding the seamed metal tube (20c), of locating the seam in a lower portion of the tube (20c) and reheating at least that lower portion of the tube (20c) to melt the coating (56). The coating (56) is thereby caused to flow downwardly over and to coat the inner surface of the seam. The result is a seamed tube (20c) with a more corrosion resistant seam region.
Patent CA-2215562-A1 (CA)
Inventor: MORAN STEVEN ALAN
IPC: H02H3/38
Filed: 1997-09-15
Abstract: A digital network protector relay samples the polyphase current, network voltageand phasing voltage at 16, and preferably 32, times per cycle so that up to the seventh and fifteenth harmonics, respectively, are eliminated from the sequence calculation used to make trip and close decisions.  The relay also provides metering, forward overcurrent protection, and an anti-pumping feature, the latter of which locks the circuit breaker out if a selected number of breaker operations is exceeded during a given time interval. Sequential sampling of the polyphase current and voltages by a single analog to digital converter reduces the cost of the relay.  In order to accommodate metering and extraction of the fundamental components of the current and voltages for the sequence calculations, the polyphase current and network voltage are sampled sequentially in a first order for a given number of cycles and then in a second reverse order for the same given number of cycles.
Patent CA-2216896-A1 (CA)
Title: Protective sheild for a blood glucose strip
Inventor: SOHRAB BORZU
IPC: B01L99/00
Filed: 1997-09-26
Abstract: A modified blood glucose test strip reduces the risk of contamination when it is used with a blood glucose meter. The modified strip has adhered to its top surface a protective shield that is preferably cut from a sheet of transparent plastic. The shield permits access to the sample-receiving surface of the strip, but prevents contamination of the meter by the user, because it covers a part of the meter that adjoins the strip when the strip is installed in the meter. Similarly, the shield protects a user from contacting a potentially contaminated area of the meter. The modified strip finds particular advantage in a hospital or other setting where several persons may use the same meter.

Patent CA-2230265-A1 (CA)
Title: Rotating consistency transmitter and method
Inventor: HILKER ROBERT J
IPC: G01N11/14
Filed: 1996-09-04
Abstract: A rotating consistency transmitter (2) and method of measuring the viscosity, consistency, concentration or the rheological properties of a flowing multi-purpose material in a pipeline (5) by measuring the torque acting on a rotating shaft (4), which at one end is driven by a motor (15) and at the other end is attached to an impeller (14) directly positioned inside the pipeline (5). The rotating shaft (4) is made up of three concentric shafts which are aligned with each other and attached together so that a single motor (15) may be used to rotate this rotating shaft (4). The rotating shaft (4) consists of an outer drive shaft (19), a middle sensor shaft (23) and an inner reference shaft (27). The sensor shaft (23) is connected at one end to the drive shaft (19) and connected at the opposite end to the inner reference shaft (27). When the material is present in the main pipeline (5) and in contact with the impeller (14), the rotation of the impeller (14) is impeded, thereby producing a torque across the sensor shaft (23). This torque causes a twisting action on the sensor shaft (23) which may be determined by measuring the angular displacement between the drive shaft (19) and the reference shaft (27). The angular displacement is measured by passing a focussed light beam across two optical disks (28, 29), one being attached to one end of the sensor shaft (23) and the other being attached to the end of the reference shaft (27). The amount of light transmitted through the two optical disks (28, 29) is a direct measure of the torque acting on the sensor shaft (23) which, in turn, directly relates to the drag forces acting on the impeller (14).

Patent CA-2240340-A1 (CA)
Title: Mixed flow liquid ring pumps
Inventor: SWEET DOUGLAS FREDERICK
IPC: F04D31/00
Filed: 1998-06-11
Abstract: A comically ported liquid ring pump has one or more port structures with cone angles in the range from 15 degrees to 75 degrees. These cone angles are substantially greater than previously used cone angles (most commonly about 8 degrees). The large cone angles of this invention give the fluid flowing between the cone and the rotor significant components of both radial and axial velocity. Large cone angles also allow the port structure(s) to be made axially shorter, which has a number of important advantages such as shortening the unsupported length of the rotor shaft.      These attributes of the present pumps are helpful for such purposes as allowing the length-to-diameter ratios of the pumps to be economically increased. In addition, the pumps of this invention retain many of the desirable attributes of comically ported pumps.
