System for generating electricity by using gravitational mass and/or momentum of moving vehicle

A mechano-electrical energy generation system generates electrical energy from the passage of a vehicle over an inclined ramp assembly. This assembly includes an incline ramp that is rotatable about an axis proximate a vehicle roadway surface, and a safety decline ramp hinged with and rotatable with the incline ramp. The incline ramp is coupled via a roller assembly to a gravity wheel that drives a flywheel coupled to an electrical generator. As a result, passage of the vehicle over the incline ramp rotates the wheel via the roller assembly and drives the flywheel so that the electrical generator outputs electrical energy. When the vehicle exits the safety decline ramp, a counterweight rotates the wheel in a reverse direction, so as to bring the incline ramp and safety decline ramp to back to their original inclined positions above the roadway surface.

Snow Shovel

The snow shovel easily and with minimal effort, scoops up a pile of snow, pivot and wheels the contents to another location, whereupon operation of a lever releases its load. The telescoping frame and rotatable handle provides a selection of lockable positions. The front mounted scoop head is pivotally mounted to the lower end of the frame. Upon activation of a release lever, the scoop head is allowed to rotate downward, releasing its load. A wheel assembly mounted to an intermediate portion of the frame supports the shovel in an inclined position, allowing the user to concentrate on applying force in a forward direction rather than expending effort lifting the handle. Furthermore, the wheel assembly acts as a fulcrum whereby downward pressure on the handlebars of the shovel elevates the scoop for ease of transport. The wheel assembly may be rotated towards the frame when not in use.

Vegetation configuration method for preventing water and soil loss of mine dump of dry-hot valley

The invention discloses a vegetation configuration method for preventing the water and soil loss of a mine dump of a dry-hot valley. The method comprises the following steps: performing topsoil stripping on the dump; building an intercepting ditch, a drainage ditch and a water collecting tank on a platform of the dump; screening vegetation types, including shrubs, herbs and liana, suitable for growing in the mine dump of the dry-hot valley; performing targeted planting; after the vegetation of the mine dump is planted, enclosing the dump by using a wire mesh or a fence to prevent a slope surface from being destroyed by domestic animals. According to the principles of soil and water conservation and restoration ecology, vegetation species are reasonably combined by aiming at that the habitat of the mine dump of the dry-hot valley is severe and different slope positions have different soil erosion intensity and water conditions, so that a reliable technical path is provided for recovering the vegetation in a mining region as quickly as possible. Moreover, the vegetation configuration method for preventing the water and soil loss of the mine dump of the dry-hot valley has the characteristics of high operability and high comprehensive benefit.

Dock leveler with inflatable bag

An air operated dock leveler is provided to selectively raise and lower a deck with an extendable lip. The deck includes a downwardly extending deck lift arm. An air lift assembly includes a single chamber, inflatable bag positioned between a stationary lower bag support and movable upper platform. A pull line is secured to the platform and the deck lift arm. When actuated, a blower inflates the bag and raises the platform. The pull line pulls the deck lift arm forward and raises the deck to an inclined position. When the blower is turned off, the ramp descends until the now extended lip engages the bed of a truck. After loading or unloading the trailer, the bag is reinflated to raise the ramp and retract the lip. The blower is then turned off, and the ramp descends to its stored position.

Tailgate-securing dump apron for dump trucks

A dump apron for a dump truck, the apron pivotally mounted around a lower end of the dump opening at the rear of the dump body, and movable in response to the tilt position of the dump body between a lower flow-channeling position and a raised tailgate-securing position. In the tailgate-securing position the apron serves to seal leaks of the loaded material around the tailgate, and to function as a secondary lock to back up the tailgate's primary latching or locking mechanism. In the preferred form, the apron is held at an acute angle to the closed tailgate in the raised tailgate-securing position, forming a trough for collecting particulate material leaking around the tailgate from the loaded dump bed, and allowing visual inspection of the lower end of the tailgate and the tailgate's primary lock.

Offset valve system for downhole drillable equipment

Float equipment is constructed to have the check valve in an offset and / or skewed position with respect to the centerline of the tubular housing that is part of a string. The design is applicable to poppet type check valves as well as flapper type valves that are actuated with a flow tube. The off center and / or skewed position of the valve components allows the cutting structure on a drill bit, rather than the nozzle area on the bit bottom to make intimate contact with the valve components to accelerate the milling one of the assembly and the making of additional hole beyond the recently cemented string.

Dual-carrier ABSK communication system on basis of same narrow-band filter

The invention relates to a dual-carrier ABSK communication system on the basis of the same narrow-band filter, which comprises a dual-carrier ABSK modulator and a dual-carrier ABSK demodulator. The dual-carrier ABSK modulator is used for alternately modulating each data bits of a path of data sequence with a code rate of 2Rbps onto two paths of ABSK signals of which carrier frequencies respectively are fc1 and fc2 and both the code rates are Rbps; on the two paths, a T time interval is reserved between positions at which each path of '1' code element appears, i.e. the simultaneous appearance of '1' on the two paths of carrier frequencies can be completely eliminated at an initial end; and T represents a code element period of the data sequence; the dual-carrier ABSK demodulator comprises the narrow-band filter of which both left and right transition zones are very precipitous; and when the carrier frequencies fc1 and fc2 are respectively positioned at the high-slope positions of the left and right transition zones, the narrow-band filter utilizes the slope phase demodulation characteristic to convert phase information of a double-carrier ABSK receiving signal at the position of each path of code element '1' into obvious and strong parasitic amplitude modulation impact, so that an envelope detector can output an impact envelope pulse which is naturally combined into the code rate 2Rbps.
