Patent CA-2186293-A1 (CA)
Title: Lath cutter and placer
Inventor: GRINDER DANIEL A
IPC: B27M3/00
Filed: 1996-09-24
Abstract: A strip cutter system combined with a strip placer is disclosed.  Strips are used in the packaging of finished lumber to provide lateral stability and shear strength to the stacked package. The strips are cut from surplus lumber and are dispensed onto the lumber package simultaneously as they are cut, thereby eliminating the need to cut bundle, store, handle and load strips into a strip dispensing device. The raw material "blocks" for the strips consists of lumber of nominal 2" thickness and any width, trimmed to approximately four feet long to match the width of thelumber package. Such material is readily available as a by-product in any lumbermill. The blocks are loaded on edge into a storage pocket on the top of the strip cutter and placer so that the bottom edge of the bottom block bears by gravity against stops in the cutting zone. The blocks may be softened by pre-conditioning in hot water, steam or by heating methods such as microwave and/or electric heating elements.  When a strip is required, a sharp knife the length of the block is drawn laterally across the bottom edge of the block slicing off a strip approximately 1/8" thick.  The strip falls by gravity onto the top of the lumberpackage while retained between guides which extend from the lower side of the strip cutter and placer and rest on the top of the lumber package.  Alternatively, a lowering device may be added to receive the strip as it is cut and then lower itand place it onto me top of the lumber stack. Additionally, a sweeping device may be added to move a defective strip to one side and allow a second strip to be placed next to it.  The number of strip cutter and placer units on a complete system depends on the maximum number of locations on a stack of lumber at which strips would be placed on one tier of lumber.

Title: Automatically sealing cup
Inventor: BELCASTRO DOMENIC
IPC: A47G19/22
Filed: 1996-11-06
Abstract: An automatically sealing cup composed generally of a cup body, a lid sealingly and releasably connected with the cup body, and an automatic sealing feature that includes, generally, a flexible tube communicating with the interior space of the cup body, an aperture in the lid through which the flexible tube sealingly passes, a pivotable handle associated with the lid wherein the position of the handle determines pinching or unpinching of the tube, and, consequently, sealed and open states, respectively, of the automatically sealing cup, and a biasing member associated with the lid which automatically biases the handle to provide the sealed state. To switch the automatically sealing cup to the open state in which liquid may be extracted therefrom through the tube, a user must continuously apply pressure to the handle, upon the cessation of which the automatically sealing cup automatically reverts to the sealed state.

Patent CA-2191636-A1 (CA)
Inventor: PAWLOWSKI NORMAN JR
IPC: B41J2/175
Filed: 1996-11-29
Abstract: The connector assembly includes an outlet assembly on an ink supply container and an inlet assembly mounted to a printer station.  The outlet and inlet assemblies have an outlet and inlet valve respectively.  The outlet and inlet valves are simultaneously rotatable into open positions to allow ink flow from the supply container to an ink delivery tube on the station.  The outlet and inlet assemblies also have a hook and a latch, respectively, that engage when the outlet and inlet valves are coupled and are in the open position, thereby preventing the outlet assembly from being uncoupled from the inlet assembly when either the outlet or inlet valve is in the open position.

Title: Adaptive control system for a medical ventilator
Inventor: TOBIA RONALD L
IPC: A61M16/00
Filed: 1997-03-04
Abstract: A control system for a single-valve controlled medical ventilator adaptively invokes separate flow delivery or flow exhaust control functions in response to the sensed dynamic state of the ventilator without any dependence on measured patient parameters. The control system selects either the flow delivery control system or flow exhaust control system based on a determination of the mode in which the ventilator is operating. The determination is made using a sensed ventilator operational parameter, such as the ratio of manifold pressure to flow output, to select the appropriate control function. A hysteresis routine is provided to prevent "hair triggering"  between the flow delivery and flow exhaust control systems.

Title: Artificial airway device
Inventor: BRAIN ARCHIBALD IAN JEREMY
IPC: A61M16/04
Filed: 1996-10-03
Abstract: A gastro-laryngeal mask (10) features softly compliant construction of the distal half of the mask (13), wherein the mask (13) is of generally elliptical configuration, with an inflatable peripheral cuff (18) to seal and support the mask (13) around the laryngeal inlet (17). A back cushion (25) is inflatable to engage the back wall of the pharynx and thus to forwardly load the peripheral cuff seal (18) to the laryngeal inlet (17). An evacuation tube (23) for external removal of a possible gastric discharge completes an evacuation or discharge passage (26) contained within the mask (13) and opening through the distal end of the peripheral cuff (18). Special provision is made for assuring integrity of the discharge passage (26) within the flexible distal half of the mask (13), i.e., assuring against collapse of the distal-end half of the softly compliant evacuation tube (26) in the distal region of the mask (13), such that inflation of the mask (13) does not compromise viability of the evacuation tube (23) by compressing softly compliant material of the evacua-tion tube (23) during periods of mask (13) inflation. The special provision also favors such collapse of the mask (13) when deflated as to provide a leading flexible edge for piloting a safe and correct advancing insertional advance of the deflated mask (13) in the pa-tient's throat (15), in avoidance of epiglottis (16) interference and to the point of locating engagement in the upper sphincter of the oesophagus (24).

Title: Fluidic element noise and vibration control constructs and methods
Inventor: ANDERSSON ANDERS O
IPC: G10K11/162
Filed: 1997-09-10
Abstract: Fluidic constructs, including grouped stacks of fluidic elements, that provide countersound to control sound in a noisy environment, prevent radiation of sound from vibrating surfaces, reduce sound-induced vibration of surfaces, and absorb sound that might otherwise impact on surfaces, are provided. These constructs may have a wide range of geometries for specific applications, but generally include a face plate on one side, and a back plate on the other side. Supply ports on the back plate provide a supply of fluid that flows through the construct, while undergoing acoustic modulation through fluidic amplifiers. The face plate includes input ports that sense sound waves to be controlled, and transmits this sound to influence the acoustic modulation of the supplied fluid. The construct produces an amplified output, having sound out of phase with the sound sensed by the input ports, at output ports on the face plate in a sufficient volume to substantially neutralize incoming sound waves, or reduce sound radiation from an object. Any sound produced by the construct of the invention that is substantially in phase with sound to be neutralized is dumped at a sufficient distance from the produced countersound to minimize interference.
