Patent CA-2881166-A1 (CA)
Inventor: WOODS TIMOTHY JOHN
IPC: F03G7/10
Filed: 2015-02-06
Abstract: This apparatus provides perpetual motion in virtually any medium without the need of fuel, or expensive parts. A lever arm unit forces a Mercury wheel against the edges of a very large wheel and a very small wheel. The large wheel moves easier than the small wheel, and connects to a series of the wheels that eventually return motive force to the small wheel from its other side via a 'Venus' sprocket chain. A feedback loop is formed and the motion is perpetuated until the force is removed from the lever arm unit.

Abstract: A power-off brake for stopping a rotating shaft comprises a solenoid including a coil and armature, an opposing plate axially spaced from the armature, and a ball carrier rotor between the armature and opposing plate. The ball carrier rotor rotates with the shaft and carries spherical balls in recesses angularly space about the shaft. The armature and opposing plate have respective braking surfaces. In one embodiment, at least one braking surface is ramped to urge the plurality of balls radially outward against an internal surface of a surrounding outer race as the armature is forced toward the opposing plate under spring loading when current to the solenoid coil is shut off.

Title: Gas lock resolution during operation of an electric submersible pump
Inventor: DOWLING MICHAEL A
IPC: E21B17/10
Filed: 2014-04-22
Abstract: Gas lock resolution during operation of an electric submersible pump is provided. An example method, module, or computing hardware with software product, detects a gas lock during current operation of an electric submersible pump (ESP) and intervenes to relieve the gas lock without stopping the ESP. After sensing a gas lock condition, an example module calculates a pump speed for attempting gas lock resolution. The example module may decrease the speed of the ESP to flush the gas lock, and then reaccelerate the ESP to check that the gas lock has been eliminated. The example module may apply one or more stored motor speed patterns that iteratively seek a pump speed that succeeds in clearing the gas lock, without stopping the ESP. The example module has built-in protections to protect the ESP from thermal overload and other damage.

Patent CA-2910699-A1 (CA)
Inventor: WHITE CHESTER
IPC: A42B3/06
Filed: 2014-04-30
Abstract: A Body Impact Bracing Apparatus is introduced for field sports such as hockey and American football but, further, for motor vehicle competitive racetrack and arena sports wherein a protective helmet is expected to provide adequate protection against head trauma. The default vulnerability in such hazardous events is the lack of solid securitization of one's neck. The novel art is designed to protect the wearer against external impact injuries to the head but only to the extent that the neck is solidly immobile at instance of an impact exterior to the protective apparatus. This has been accomplished by a revolutionary technique utilizing electronic circuits which, moreover, correspond with a torso bracing protective mechanism providing the wearer still additional safety measures against bodily impact and brain injuries thus circumventing adverse neurological damage. This novel apparatus presumes optimal protections based upon safeguarding the integrity of the CNS: spinal cord, neck, and head.
