Abstract: A geothermal plant, for extracting energy from a geothermal reservoir located below the ocean bottom, includes a floating platform; a riser that extends from a well drilled into the geothermal reservoir, to the floating platform; an electrical pump having a mechanical actuation part located in a bore of the riser, and an electronic part located outside the riser, wherein the electrical pump is configured to pump a geothermal liquid from the geothermal reservoir to the floating platform; and a power plant located on the floating platform and configured to use a steam produced by the geothermal liquid to generate electrical power. The electrical pump is placed at a depth of the riser where the geothermal liquid is in a single-phase.

Abstract: A pulse generator is disclosed. The pulse generator can include a pulsed switch, such as a diode. The pulsed switched can be connected between an input source, such as an oscillator and a frequency multiplier.

Abstract: A remote age verification system and method for ensuring the recipient of a delivery of age restricted items, such as alcoholic beverages, is of the appropriate age and has the requisite funds is implemented through a verifying software application loaded on mobile device which employs an account setup method and an age and funds verification method. The account set up method operates to confirm a user's eligibility to place orders for the delivery of age restricted items and includes the steps of extracting and saving identification data, extracting and saving credit card data, ensuring identification and credit card information are valid and match, and activating an account. The age and funds verification method operates to facilitate the ordering and delivery of age restricted items in a way that minimizes ensures a purchaser is old enough and has the funds to make the order.

Abstract: A pulse generator is disclosed. The pulse generator can include an ac source for providing an ac signal. A pulsed switch can be connected to an ac output of the ac source that is adapted or configured to generate a pulsed output from the ac signal and a non-linear frequency multiplier adapted or configured to shorten the pulses of the pulsed output. The pulsed switch can include a mixer.

Abstract: A digital walker comprising a walker with a digital monitoring device and digital display are described herein. The digital monitoring device comprises at least one sensor. The sensor may be a biological or physiological sensor, a geographical or distance sensor, or a speed sensor. The data from the sensor may be displayed on the digital display.

Abstract: A pulse generator including a pulsed switch (12), for example a diode, connected between an input source (14), such as an oscillator, and a frequency multiplier (16).

Abstract: A hybrid single-phase variable reluctance motor system has a stator (1) having a pair of oppositely disposed salient main poles (4) provided with main windings (12) and at least one pair of oppositely disposed salient auxiliary poles (5, 6) provided with auxiliary windings (13, 14) and disposed intermediate the main poles (4) on the stator (1). Furthermore the motor system has a rotor (2) having a pair of oppositely disposed salient poles (7) without windings. Additionally the motor system includes a control circuit (11) for rotating the rotor (2) during normal running by supplying current pulses to the main stator windings (12) in synchronism with rotation of the rotor (2) and for rotating the rotor (2) on starting by supplying current pulses to both the main and auxiliary stator windings (12, 13, 14) in synchronism with rotation of the rotor (2).

Abstract: A two stroke cycle engine has an engine block with a cylinder bore accommodating a piston. An exhaust port connects the cylinder bore to an outside of the engine block. An exhaust port control valve mechanism within the engine, according to this invention, includes a valve pivotally mounted in the exhaust port between the cylinder bore and the outside for rotation between an open position and a closed position. The valve defines an upper timing edge of the exhaust port. An insert fills a volume in the exhaust port between the valve and the outside, thereby improving flow efficiency of the exhaust port.

Abstract: A two stroke cycle engine has tiered cooling jackets in the cylinder block with upper and lower jackets separated by a diaphragm wall. Transfer openings in the diaphragm and downward portions of the lower jacket direct coolant flow around exhaust ports and preferentially along the exhaust port side of the engine cylinder openings. A cylinder head gasket controls outflow from the upper jacket to the cylinder head through transfer holes placed preferably on the exhaust side of the upper jacket to provide overall control of flow in the cooling jacket system.

Abstract: Combinations of split and valved exhaust ports are provided in a ported two cycle engine with divided emission control system to provide better control of the division of exhaust gas flow to the two converters.

Abstract: A two-stroke cycle spark ignition cylinder fuel injection engine is provided with an exhaust emission control system that separately treats hot blowdown gases and uses the hot treated gases to warm the scavenging gases for further treatment. Various exhaust gas separation concepts are described for use in separating the blowdown and scavenging portions of the exhaust gas discharged from the cylinder exhaust ports.
