IPC: B62B7/04
Filed: 2000-04-14
Abstract: A foldable baby stroller having left and right side front wheel supports with a front wheel mounted to a forward end, and a laterally extending rear axle with a rear wheel mounted at each end. Further included are left and right side rear wheel supports, each having a lower end attached to the axle and an upper end portion with an upper end; and left and right side handle supports, each having forward and rearward ends with a handle spanning between. Also included are left and right side folding assemblies, each having a pair of mounting plates and a guide pivotally attached therebetween. The rearward end of one of the front wheel supports is fixedly attached between each plate pair.  The forward end of one of the handle supports is pivotally attached between the plates and rotatable relative to the front wheel support between unfolded and folded positions. The upper end portion of one of the rear wheel supports is positioned between the plates and pivotally attached to the forward end of the handle support for application of a drive force thereto.  The guide has an aperture with the upper end portion of the rear wheel support slidably disposed therein. The guide and guide aperture are configured to rotate the rear wheel support with rotation of the handle support in response to the drive force applied to the rear wheel support during the rotational movements of the handle support, and to slide the upper end portion of the rear wheel support in the guide aperture with rotation of the handle support in response to the drive force applied thereto during a second rotational movement of the handle support. The rotation and sliding movement of the rear wheel support moving the rear wheel support between an unfolded and folded positions. Alternative style guides can also be used. In several embodiments, each of the left and right side folding assemblies uses a pair of meshing gear segments, one being attached to the handle support and one being attached to the rear wheel support.

Inventor: DRUMMOND WILLIAM H
IPC: A61K9/08
Filed: 1998-10-19
Abstract: Methods and compositions for forming protective and/or medicated films on body tissue. Liquid compositions contain a hydrophobically modified polymer, other than an esterified lower-hydroxyalkyl-subsituted cellulose, suspended or dissolved in a solven.  The modified polymer is soluble in the solvent but insoluble in body fluids.  The compositions may optionally contain a separate medicinal component, i.e., one which is present in addition to any medications, if any, present in the solvent, in the modified polymer and in any other additive components such as flavors, skin penetrants, preservatives, other solvents for the additives, etc. A protective and/or medicated film is formed in situ upon body tissue by applying the liquid composition to the tissue and separating the solvent from the composition, e.g., by vaporization.
Patent CA-2306637-A1 (CA)
Inventor: WHITMAN TIMOTHY W
IPC: B29C48/03
Filed: 1998-10-05
Abstract: A continuous flow filter changer (10) for a fluid having a filter carrier assembly (36) for intermittent sliding transition displacements in a filter channel to align adjacent filters (38) thereon successively with a filter aperture in the flow passage (28). The duration of each such transition is substantially less than that between transitions. A ring shaped seal (46) sealingly connects between the flow passage (28) upstream thereof and a filter (38) aligned with said aperture to prevent fluid flow except through said filter (38). The clearance for sliding between the filter carrier assembly (36) and the filter channel is controlled to allow for such displacements while limiting the fluid leakage from the filter channel during a single transition to a predetermined level.

Title: Cooking utensil
Inventor: GANTOS JILL L
IPC: A47J36/18
Filed: 1999-09-15
Abstract: A cooking set including a perforated insert (14) and a support ring (12). The support ring (12) is adapted to fit within and rest upon the rim of a conventional cooking pot (16), or dutch oven to support the inset at various heights. The inset (14) is adapted to fit within the support ring (12) so that it can be lowered into the raised out of the pot.  The support ring (12) defines a set of notches (82a, 82b, 82c) and the inset includes a set of corresponding protrusions (46, 48, 50). When the notches and protrusions are aligned, the inset can be lowered into the raised out of the pot. When the protrusions are not aligned with the notches, they can engage and rest upon the support ring to support the inset in a raised position. In the most preferred embodiment, the inset includes multiple sets of protrusions, each set positioned at a different height along the wall of the inset. Each set of protrusions permits the inset to be supported at a different height.

Title: Retractable roller system for handling cargo
Inventor: LANGSTON FRANCES J
IPC: B65G13/11
Filed: 2000-05-15
Abstract: A retractable roller system has a main channel mounted on the floor of a vehicle into which cargo is to be loaded. A pneumatically actuated bladder is mounted along the bottom of the channel and a roller tray on which a plurality of roller members are rotatably supported is mounted in the channel above the bladder. Flange members extend inwardly from the side walls of the channel at different vertical levels. Flange members extend outwardly at different vertical levels from the opposing side walls of the roller tray. The rollers are raised to handle the loading of cargo by inflating the bladder and lowered to recess the rollers below the level of a cover plate to keep the cargo in a desired location. The cover plate utilizes a minimum number of screws in conjunction with a mating coupler plate and slots and for adjacent units which engage pins on the channel to provide secure retention of the plate yet facilitating ready removal when the roller tray needs to be removed for repair or replacement. Such removal can be readily accomplished by tilting the roller tray sideways to permit the side flanges of the roller tray to clear the side flanges of the channel.

Patent CA-2321020-A1 (CA)
Inventor: NANDY BISWAJIT B
IPC: H04L12/56
Filed: 2000-09-27
Abstract: A system and method for transmitting data in a data communications network, using a transmission control protocol, to provide reduced acknowledgment control traffic, error recovery and congestion control. A communications link is established between a transmitter and a receiver. Setting the communications link includes setting a network congestion window to an initial length. A sequence, or stream, of data packets is sent from the transmitter to the receiver. The receiver detects any missing packets, by examining the sequence numbers of the incoming packets, and sends negative acknowledgments, generally no more than four, to the transmitter identifying the missing data packet. When the transmitter receives a negative acknowledgment, it decreases the length of the congestion window, and re-transmits the missing packet. Detection and use of round-trip time, re-transmission time-out are provided.
