IPC: H04Q7/30
Filed: 1995-07-10
Abstract: The process of the present invention enables a mobile radiotelephone to operate at a 100% duty cycle while providing closed loop power control. The base station measures the signal to noise ratio of the signal from the mobile and compares (305) that SNR with the SNR threshold values the base station has for each data rate the mobile is capable of transmitting. The base station then generates power control commands (310) to instruct the mobile to change its power depending on the outcome of the comparisons.

Patent CA-2204462-A1 (CA)
Inventor: NEWTON TIMOTHY PATRICK
IPC: B29C33/34
Filed: 1997-05-05
Abstract: Automated means for hydrating contact lenses. A first robotic assembly transports a first hydration carrier to a first rotary transfer device. The first rotary transfer device transfers the carrier to a second robotic assembly that immerses the carrier in a hydration bath. Each lens is transferred from a respective lens mold to a lens transfer means during the bath. The second robotic assembly transfers the carrier to a second rotary transfer device that rotates and transfers the carrier to a third robotic assembly. The third robotic assembly removes the lens molds and lens mold carrier from the lens transfer means. The lenses are transported with the lens transfer means and assembled with a hydration base member to form a second hydration carrier. After subjecting the lenses to extraction processing, the lens transfer means is dis-assembled from the hydration base member to provide hydrated lenses in a concave lens holding means.

Title: Method of necking an impact extruded metal container
Inventor: GODA MARK E
IPC: B21D51/26
Filed: 1995-11-21
Abstract: A method of forming an elongated, narrowed neck (225) on an impact extruded metal container, in which a larger portion is trimmed from the open endof the container than is necessary merely to produce a straight unwrinkled edge.The trimmed part (111a, 111b) is sufficiently long that the metal at the new edge (112a, 112b) formed by trimming comprises substantially more formable metal than the metal which would have been present at the edge produced by normal trimming. The increased formability occurs because excess impurities which migrate to the open edge of the container are largely removed by the deep trim. The method is further assisted by trimming the end of the neck again partway through a series of neck-forming dies (120), and by using compressed air in the first few dies to aid in ejecting the containers from the dies.
Patent CA-2207248-A1 (CA)
Title: Padded chair construction
Inventor: OLSON OGDEN R
IPC: A47C7/18
Filed: 1997-06-06
Abstract: A form for constructing a seat or back cushion of a padded chair comprises a rigid unitary body member having a central relatively flat portion between two marginal edges formed with updating ridges. The ridges define a central depressed portion which is capable of receiving layers of foam. A separate foam layer covers the central layers of foam and wraps over and around the edge ridges to pad the ridges. The ridges thereby serve to reduce precompression of the central foam layers after the form is finished with a covering of upholstery. A chair having cushions with enhanced softness is thereby achieved.

Patent CA-2216440-A1 (CA)
Inventor: BOWMAN TIMOTHY S
IPC: H02G3/18
Filed: 1997-09-25
Abstract: A non-metallic floor box for use in electrical in-floor power and communication distribution systems includes a plurality of sets of vertically aligned indexing teeth formed in the interior of the housing side wall. An adapter ring is sized for insertion into the housing interior for supporting an activation kit above the housing interior compartment. The adapter ring has flanges extending from its periphery which are positioned to reciprocally mate with the vertical rows of teeth when the adapter ring is inserted into the housing interior compartment. The flanges and teeth are constructed to permit the ring to be inserted into the housing but to restrict its removal from the housing after its insertion therein. An activation cover is securable to the top of the adapter ring and extends beyond the perimeter of the side wall to limit the distance the adapter ring can be inserted into the housing. The floor box accommodates dual services through the use of two sets of parallel aligned conduit hubs and a divider which is insertable into the housing interior between the two sets of conduit hubs. The closed top of the housing acts as a concrete cover during the pouring of the floor, and as a temporary debris cover after it is cut off but prior to activation of the floor box. Gradient markings on the interior of the floor box provide a quick and accurate measurement of interior floor box volume for inspection and building code compliance.
