Patent CA-2475453-A1 (CA)
Title: Transmission with minimal orbiter
Inventor: GLEASMAN VERNON E
IPC: F16H3/56
Filed: 2002-11-21
Abstract: A transmission has only a single, minimal orbiter in which an input gear and an output gear, each being connected to separate input and output shafts, are interconnected through an orbiting cluster gear that meshes with only the input and output gears. The cluster gear is carried by a web that is itself rotated by a hydraulic control motor through a first clutch. When rotation of the web is prevented, rotation of the input gear produces rotation of the output gear at a predetermined reduction of the input drive, this gear reduction being continuously diminished proportional to the speed of rotation of the web in a first direction. When the vehicle reaches highway speeds, the control motor is disconnected and a second clutch is activated to connect a predetermined overdrive that is located between the engine drive and the transmission rather than being conventionally positioned between the transmission and the final output shaft.

Title: Thermokeratoplasty system with a calibrated radio frequency amplifier
Inventor: GOTH PAUL R
IPC: A61F9/013
Filed: 2004-11-18
Abstract: A radio frequency amplifier for a system that can correct the patient's vision by reshaping the cornea by applying a proper amount of RF energy. The system includes an electrode that is connected to the output of the radio frequency amplifier and placed in contact with a cornea.      The radio frequency amplifier delivers a RF current to the electrode that flows through and denatures the cornea then returns back to the radio frequency amplifier through a return electrode. The electrode can be placed in a circular pattern about the cornea to correct for a hyperopic condition. To effectively provide for vision correction the radio frequency amplifier should ideally provide power at a desired power curve. The radio frequency amplifier is calibrated to provide an actual power curve that is within +/- 10% of the desired power curve within the operating range of the procedure. This insures that the right amount of power is applied to the cornea during the specified activation time.

Title: Selective stimulation with selective water reduction
Inventor: FRANCINI PIA-ANGELA
IPC: C09K8/74
Filed: 2003-11-13
Abstract: A method for preferentially treating a subterranean formation having at leas t one primarily oil producing layer and at least one primarily water producing layer. The method involves the steps of providing a water shut-off gel into the formation to preferentially treat the water producing layers. This is followed by providing a viscoelastic fluid into the formation, where the viscoelastic fluid is broken by hydrocarbon, thereby remaining and viscosifying primarily in the water producing layers. Finally, a reactive fluid, such as an acid fluid, is provided. The reactive fluid treats primari ly the oil producing layers because the viscoelastic fluid and the water shut-o ff gel prevent the reactive fluid from substantially entering the water produci ng layers.
