Title: Child resistant spout package
Inventor: FUCHS TIMOTHY J
IPC: B65D50/04
Filed: 1991-10-15
Granted: 2003-09-16
Abstract: A child resistant spout package wherein a plastic container includes a neck and a spout extending axially outwardly through said neck and the neck includes internal threads that are engaged by external threads on a closure which projects beyond the finish to accommodate the spout. The finish of the container includes an axially extending flexible wall.      Interengaging ratchets are provided between a flange on the closure and the flexible wall of a container and are operable to normally permit rotation of the closure to apply the closure to the container but prevent rotation of the closure for removing the closure from the container. When the flexible wall is flexed at points spaced from the ratchet, the wall is deformed sufficiently to prevent the ratchet on the wall and the closure from engaging so that the closure can be rotated to remove the closure from the container.

Title: Retractable lifeline safety device
Inventor: WOLNER JAMES THOMAS
IPC: B66D5/04
Filed: 1991-10-25
Granted: 2000-05-02
Abstract: A retractable lifeline safety device usable by workers performing tasks at great heights above the ground. The mechanical components of the safety device are contained within a sealed housing that is filled with a viscous fluid. The sealed housing prevents the introduction of dirt, moisture and other foreign matter into the mechanical mechanism of the safety device, reducing the likelihood that those components may be fouled by dirt and corrosion, which in turn could greatly reduce the effectiveness of the safety device. The safety device is attached to the structure on which the worker is performing the task, and a lifeline such as a cable is withdrawn from the housing thereof, the end of which is attached to a belt or harness worn by the worker. The cable may be easily drawn out of the housing in response to the worker moving about normally in the appropriate work space, and the cable is automatically drawn back into the housing of the safety device as the worker draws closer thereto. However, should the worker fall, a brake within the safety device is automatically engaged by a centrifugal clutch, stopping the worker's descent.

Title: Thumb-activated actuating member for imparting reciprocal motion to push rod of a disposable laparoscopic surgical instrument
Inventor: SLATER CHARLES R
IPC: A61B19/00
Filed: 1992-04-03
Granted: 1995-02-07
Abstract: An actuator for a laparoscopic surgical instrument imparts reciprocal motion to a push rod surrounded by a hollow tube.  The actuator includes a plastic housing which fixedly engages the hollow tube, and a lever which fixedly engages the push rod and pivotally engages the housing.  The housing also preferably includes an integral handle.  When the handle and lever are manipulated by the user such as by pivotal movement of the lever, reciprocal motion is imparted to the push rod relative to the hollow tube.  The lever also includes an external unevenly surfaced portion which when frictionally engaged by a digit of a human hand will impart pivotal motion to the lever, and hence reciprocal motion to the push rod.

Granted: 2003-10-14
Abstract: It is an object of the present invention to provide a means by which clothing may be made more effective in its role in assisting temperature regulation, by: 1) providing in-creased heat exchange by means of reduced insulation (her-ein defined as "lower insulatory capacity") of temperature-sensitive sites (11, 16, 14) - reducing insulation of tempera-ture-sensitive areas not protected by "fat pads"; and/or 2) providing for increased vapour exchange by means of spe-cific ventilation of temperature sensitive areas (herein de-fined as "increased ventilatory capacity") - allowing flexibil-ity for rapid increases in heat generation owing to facility for improved vapour exchange e.g. the loss of excess heated air or humidity, by, for example, convection and evapora-tion of sweat from the surface of the skin.

Abstract: An improved package is described for use in packaging a wide variety of products, and in particular perishable food and horticultural products. The products are placed within a container of the type which establishes a modified atmosphere environment therein and is cooled, as by placing the container in contact with a cooling element partially surrounding the container. The cooling element may hold liquid which is evaporated to enhance the cool-ing. The container and cooling collar may be subjected to vacuum cooling. The container may include a mechanism to enhance the bulk gas transfer rate during the application of the vacuum while still maintaining the desired atmosphere within the container. The container atmosphere may be precharged with gas of a desired composition, In addition, fumigants may also be included therein.     The package is suitable for field packing applications in which the product, such as strawberries, is picked directly into the con-tainer surrounded by the cooling collar with the container and cooling collar being placed in an outer box or other receptacle.     The modified atmosphere package may be sealed and palletized prior to vacuum cooling.

Patent CA-2074883-C (CA)
Inventor: MERRY WAYNE MARK
IPC: B65B63/02
Filed: 1992-07-29
Granted: 2002-09-17
Abstract: The present invention provides a method of compacting a sheet article, for example an article of underwear, to produce a stable, substantially rigid, compacted article. This reduces space required for storage and distribution and facilitates packaging of the article. Compaction is effected by planing the article, or a plurality of articles, in a mold cavity, and subjecting them to elevated pressure for a certain time.      The pressure and time are selected to compact the article sufficiently for form the stable, rigid body, but simultaneously not being so great as to either damage the article or compact it so much that water or other liquid is required to recover the article from its compacted state to its original state.

Title: Self-healing meshed network using logical ring structures
Inventor: SANDESARA NIRANJAN BHOGILAL
IPC: H04J3/08
Filed: 1991-05-07
Granted: 1996-10-01
Abstract: Logical hybrid ring arrangements are disclosed which can withstand a cut communication path or a failed node. A logical ring is formed by a cascade of (i) physical hybrid ring segments (301-304), each composed of a pair of unidirectional communica-tion paths (e.g., 3011 and 3012) propagating multiplexed subchannels and interposed add-drop multiplexer nodes (311-319), and (ii) cross-connect nodes (320, 330) terminating the segments. Each cross-connect node routes an incoming subchannel from one segment to an outgoing subchannel on another segment. Each segment may operate at a different multiplexed signal rate, so a logical ring can be composed of segments operating at different rates. Moreover, subchannels on an incoming segment may be allocated to a plurality of outgoing segments, thereby configuring multiple logical rings which may serve to balance communica-tion traffic over the logical rings.

Title: Air spring with quick release
Inventor: JOHNSON NOEL R
IPC: D21F3/06
Filed: 1991-09-30
Granted: 1995-12-19
Abstract: An air spring apparatus (10) has quick pressure release, and rapid air exhaust, capability by means of a relatively large di-ameter exhaust port (44) in a larger, primary air spring (12) which is controlled by the action of a smaller, secondary air spring (14). The secondary air spring (14) is equipped with a check valve (56) which controls the flow of air into the primary air spring (12). The rapid exhaust of the primary air spring (12) is effected by triggering the removal of air pressure from the secondary air spring (14) through a plurality of orifices (86) in a centrally disposed guide tube (52) which permits the collapse of the smaller air spring and the accompanying removal of a valve plate (48) from a relatively large diameter exhaust port (44) of the primary air spring (12). Once the exhaust port (44) in the primary air spring (12) has been opened, the air pressure in the primary air spring (12) is immediately lowered, and the load on the larger air spring causes rapid expulsion of the volume of air in the primary air spring (12) to permit its quick deflation and collapse to a predetermined minimum height.
