Patent CA-2934500-A1 (CA)
Inventor: SPEIJERS SAM
IPC: F04D9/04
Filed: 2015-01-09
Abstract: A description is given of a system comprising a not self-priming medium pump provided with a pump head for the supply of medium, a valve which is coupled to the pump head and which comprises a passage which is operated by means of a float, and an air pump connected to the valve, wherein the system is arranged to control the level of the medium in the pump head by means of the float. The float is shaped such that, when the pump head is filled with medium, the increasing upward force of the float is sufficient to close the passage in time. By virtue of the optimized timing of, in particular, the closing, but also the opening, of the passage, both the efficiency of the medium pump and the service life of the air pump are improved, while the system is self-priming.

Title: Control apparatus for internal combustion engine
Inventor: MORITA YUSUKE
IPC: F01M1/18
Filed: 2016-09-29
Abstract: A control apparatus is applied to an internal combustion engine 10. The engine 10 comprises a water pump 24, and an oil pump 21. The apparatus makes a second motor 23 for driving the water pump 24 to drive the oil pump 21, when the first motor 22 to drive the oil pump 21 malfunctions. Consequently, when the first motor 22 malfunctions, the oil pump 21 can be driven by the second motor 23. Thus, the possibility of seizing of the sliding portions of the engine can be reduced. Further, when the first motor 22 malfunctions, the friction in the engine 10 can be reduced, since the oil pump 21 is not driven by the crank shaft.

Abstract: Collapsible structures may be formed from planar solids. The structures may be comprised of multiple planar objects hingedly connected, where each planar object may include magnetic materials (e.g., magnets, ferromagnetic metals) or electromagnetic materials. Using the magnetic or electromagnetic materials, the connected planar objects may be arranged as a single planar object with multiple layers, or may be arranged as a three-dimensional (3-D) object, where the magnetic or electromagnetic materials may be used to retain the formed 3-D object shape. Application of a current to the electromagnetic materials may cause the collapsible structure to form the 3-D object, and removal of the electric current may cause the collapsible structure to revert to a single planar object. Multiple structures may be combined to form larger structures.

Title: Automatic hot water pulsating alarm for water heaters
Inventor: LESAGE JEAN-CLAUDE
IPC: G08B1/00
Filed: 2017-05-05
Abstract: A hot water pulsating alarm system and method for electric or gas-fired water heaters is described. A sensor senses the water temperature in an upper region of the water tank of the water heater and feeds temperature signals to a controller. The controller operates an electromechanical valve connected to the pressurized cold water supply line of the water tank. Upon detecting a low temperature value stored in the memory of the controller, the controller causes a shut-off electro-mechanical valve to close and open in a predetermined sequence and during a predetermined time period. This causes interruptions of hot water being drawn from the upper region of the water tank to feed a hot water supply conduit and creating a pulsating water temperature change in hot water being discharged through fixtures connected to the hot water supply conduit. The pulsating temperature change is detected by a user person having a body part in contact with water dispensed from fixtures secured to the hot water supply conduit and indicating to the user person that the water heater will be shut-off.
