Patent CA-2214342-A1 (CA)
Title: Swivel child seat for car
Inventor: CHANGIZI LABIB
IPC: B60N2/28
Filed: 1997-10-23
Abstract: The main frame of the swivel child seat is secured to the car seat in the same manner as conventional child seats. The child seat is attached to one side of the frame by two hinges. These hinges have a locking mechanism. When the seat swings open to full capacity it locks in this open position. That way, while the child is being installed in the seat, the said seat stays fixed and does not rotate. After the child is properly positioned or removed, a slight force is then required to push the seat out of the open position and re-attach it in the original closed position, where it locks until someone pulls a cable-release mechanism to unlock it. The child seat rotates on its hinges towards the open car door. The seat can be unlocked from the side closest to the door. The hinges can be placed on either side of the seat so that it can be used on both sides of the car. The conventional child seat is uncomfortable for parents (or others) to work with: to put the child in or remove. Parents (or others) acquire back pain from bending over at an uncomfortable angle. They tend to become lazy and do the job improperly. The conventional process of inserting the child is also uncomfortable for the child. The advance that this invention has to offer is a swivel vs. a stationary seat. In terms of utility, this new child seat is more convenient and easier to use for both the parents and the child.
Patent CA-2216203-A1 (CA)
Inventor: BORLAND KERMIT M
IPC: C12N5/0793
Filed: 1997-09-22
Abstract: The invention features a method of processing cryopreserved cells by thawing and equilibrating the cells at warm temperatures (e.g., between 30°C and 43°C). Either the cell suspension in the cryoprotective medium is thawed to a temperature between 35°C and 43°C or the cryoprotective medium is equilibrated with a culture medium at a temperature between 30°C and 43°C, or both steps are carried out at the warm temperatures. By thawing and equilibrating the cryopreserved cells at warm temperatures, the viability, (especially after 3 hours of culture), and metabolic activity (i.e., diazepam metabolism) of the cells can be improved over traditional cold cell processing (i.e., at temperatures of between 2°C and 8°C).

Patent CA-2220477-A1 (CA)
Title: Hydraulic machines
Inventor: CULVERWELL GREGORY ADRIAN
IPC: F16K25/00
Filed: 1997-11-07
Abstract: The invention concerns a bore sealing valve which is operated by liquid pressure, typically water. The valve has a first member defining an internal bore of round cross-section and a second member which can move in opposite directions in the bore. One of the members has a shoulder and the other a recess accommodating a flexible seal. The seal flexes radially relative to the recess, under the effects of differential pressure in respective high and low pressure regions of the byre, when the second member moves in one direction in the bore. This makes sealing engagement with the shoulder to close the valve and isolate the high and low pressure regions of the bore from one another. The seal disengages from the shoulder when the second member moves in the opposite direction in the bore to open the valve and place the regions of the bore in fluid communication. That end of the seal which engages first with the shoulder on closure of the valve and which disengages last from the shoulder on opening of the valve is closer to the low pressure region of the bore than the opposite end of the seal. With these features, the bore sealing valve is suitable for use in a water environment.

Title: Acoustic echo elimination in a digital mobile communications system
Inventor: KIRLA OLLI
IPC: H04Q7/32
Filed: 1996-06-07
Abstract: The invention relates to a method and arrangement for eliminating acoustic echo generated in a mobile station in a mobile communications system. According to the invention, an echo suppressor is placed on the side of the mobile network for eliminating the acoustic residual echo of the echo canceller of the mobile station. The echo suppressor comprises a downlink voice activity detector (35) because it is possible that the downlink speech returns from the mobile station as an acoustic echo superimposed to the uplink signal. When the detector (35) detects the downlink speech, a selector (303) disconnects the uplink signal from the speech decoder (38) and supplies in its place noise from the generator (302). The spectral characteristics and intensity of the comfort noise are similar to those of the background noise do the operating environment of the mobile station at each moment. Generation of the noise is started after a predetermined delay from detecting the voice activity, and terminated after a predetermined delay from the end of the voice activity.

Patent CA-2227449-A1 (CA)
Inventor: MOEDER CLAUDIO
IPC: B29C59/02
Filed: 1996-07-22
Abstract: A method of creasing plastics sheet material which comprises providing a mould having the desired shape, heating the mould, and bringing the mould into contact with the sheet material under pressure. The mould has the desired shape of the end product, for example a box blank, and may contain both cutting and creasing rules as well as other product features as desired. A  single mould may be used in conjunction with a flat plate or a complementary double mould system may be used, especially for thicker materials or where a central hinge effect is required. By this means, the creasing is obtained by heat deformation (rather than simple pressure of a creasing rule) and sealing of the sheet material takes place at the same time thereby destroying elastic memory and ensuring that the dimensions of the creased area remain constant after creasing.

Title: Vehicle occupant restraint having an adjustable web tether
Inventor: CHANEY AARON
IPC: B60R22/20
Filed: 1998-04-23
Abstract: A vehicle occupant restraint having an adjustable web tether utilizes a first section of webbing that is tautly positioned between the vehicle floor and an upper mounting location. A second section of webbing extends from a floor-mounted (or wall- or seat-mounted) emergency locking retractor (ELR) and through a turning point at the upper mounting location, after which the second webbing section transitions to a shoulder belt for the occupant. In order to provide a pivot point for the shoulder belt, an adjustable web tether is mounted to the first webbing section and captures the second webbing section in sliding engagement by means of a ring. The ring of the web tether therefore provides a pivot point for the shoulder strap.      The vertical position of the web tether upon the first webbing section is adjustable, so that the height of the shoulder strap pivot point, and therefore the trajectory of the shoulder strap across the occupant, is adjustable.
