Abstract: An apparatus (10) for wrapping a wrapping film (20) over an elongate load (12), which has a generally cylindrical exterior and two generally circular or generally annular ends (18) includes two blocker rollers (32) which cradle the load (12) with its axis extending horizontally and which are arranged for rotating the load about the load axis. A dispenser (42) mounts a roll (22) of the wrapping film (20) with its axis extending vertically. The dispenser (42) is mounted on a rotatable arm (50), which is rotatable about a vertical axis. A carriage (62) is provided for mounting the dispenser (42) and for carrying the dispenser (42) and the roll (22) back and forth along the cradled load (12). Thus, the roll (22) is moved along an oblong path, whereby the film (20) pulled from the roll (22) is wrapped over the near side of the load (12), one end (18) of the load (12), the far side of the load (12), and the other end (18) of the load (12), as load (12) is rotated. The roll (22) remains at an elevation above a central portion (16) of the load (12) so as to permit the central portion (16) to remain unwrapped. <IMAGE>

Patent CA-2190671-A1 (CA)
Inventor: FOLADARE MARK JEFFREY
IPC: H04W4/16
Filed: 1996-11-19
Abstract: A system and method of using two-way paging to establish communications with a mobile party having a Personal Telephone Number (PTN).  The mobile party uses the two-way pager to transmit call control parameters which are used by the telephone network to route calls directed to the party's PTN.  The mobile party may also use the pager to transmit a location indicator which specifies the subscriber's location and informs the network of the subscriber's intention to receive calls according to a call examination procedure.  To invoke the call examination procedure, the bandwidths and protocols of all possible terminating stations associated with the subscriber's location are stored in the network on a pre-provisioned basis. Thereafter, when a call is placed to the subscriber's PTN, the network determines the bandwidth and protocol of the originating station, selects a terminating station that is located at the subscriber site and has a bandwidth and protocol most closely resembling that of the originating station, and routes the call to the selected terminating station.

Patent CA-2195026-A1 (CA)
Inventor: CORNIES ERNEST HENRY
IPC: A47K3/00
Filed: 1997-01-14
Abstract: The TUBDOOR consists of a panel door, with one or two panels, hinged to open freely into an empty tub to allow the user or caregiver to enter. The door is designed to close against a round rubber or vinyl seal to create a water proof closure. To provide pressure to the door against the seal an off-center cam locking wheel fits into a channel that is provided in the sill to accommodate this lock and a guide for the unhinged end of the door panel. This guide is a tumblerthat is inserted in the bottom of the door panel loosely and rides in the channel freely. The locking device is held in a sleeve that is widened at the top to receive a spring and a collar that is attached to a shaft and a twist handle. This lifts the shaft and cam out of the channel when not in use. To seal the door a simple push down and twist provides enough pressure to seal the panel and provide a safety lock to prevent accidental opening. As the water is on the opposite side to the seal, any pressure generated by the water would assist in the sealing. To contain any possible seepage that could occur, the sill of the door frame hasbeen fitted with a perforated drain channel leading to a seepage reservoir that is connected to the standard tub waste and overflow. In a single panel door application the tumbler guide is eliminated and replaced by the twist cam lock at the non hinged end.

Abstract: The present invention discloses a system and method relating to a perceptualizing, spatial relations module system which is designed to facilitate the development of people with learning disabilities. It gives people of any age, the opportunity to learn spatial relations, object concepts, integration of sensory functions, the position of objects, fine motor skills as well as making it meaningful for people to explore, experiment, compare, and become creative.  The flexibility of this particular modular concept enables multiple units to be connected together to form a larger sized module and enables a variety of visual, tactile, and auditory learning devices to be positioned along the inside and outside walls and even suspended from the top of the unit to enhance the learning for the impaired person.  The modular unit (1) has additional versatility is using channels (2) that enclose various interchangeable learning devices such as panels (4) designed for a variety of functions.  These channels may be integral to the frame members such as the upright (6) and longitudinal (8) members which in turn may be used to form the overall framework for the module. Also, the channels may be used as a means of joining the frame together.  Cross bars (10) may be used with similar channels to support attachment members (12) that may support a variety of the learning devices.  A top (14), which may be hinged to the frame, may include attachment points (16) to support some of the learning devices.
