Abstract:
A selectable-width push plow for removing snow or other material. The push plow is configurable in any one of several pre-defined blade-width blade configurations without requiring special tools or great dexterity to adjust, while also allowing for compact storage of the device. The push plow includes a plow blade having a first panel and a second panel pivotably interconnected to the first panel. The second panel is pivotable between a retracted position in which the bottom edges of the first and second panel extend transversely to one another, and an extended position in which the bottom edges of the first and second panel extend in a common direction. The push-plow further includes an adjustable-length handle extend substantially vertically the plow blade and a glide adjacent the bottom of each panel to promote gliding of push plow over concrete, macadam or another rough or uneven surface.
Abstract:
A method and a device for melting snow is disclosed. The snow is compressed against an outer surface of a single rotating solid of revolution (100), wherein the friction causes the snow to melt. In one example the rotating surface is a cylinder. The energy used for producing the friction dissipates very effectively into melting the snow. The melt water is near zero temperature, as energy is not used for heating the water above the melting point as the melt water spreads from the rotating surface and may be collected and discharged to sewage.

Abstract:
A snowplow assembly includes a mount assembly operatively connected to an associated vehicle, a plow blade assembly pivotally connected to the mount assembly, and a cylinder with a first end pivotally connected to the mount assembly and a second end pivotally connected to the plow blade assembly. The cylinder can include at least one resilient member. The resilient member exerts a force in a first direction when the plow blade assembly is in a first angled position, and the resilient member exerts a force in a second direction when the plow blade assembly is in a second angled position.
Abstract:
A spreader assembly may include a hopper, a spinner plate and an aperture adjustment mechanism. The aperture adjustment mechanism may include a gate supported to the frame and defining an aperture through which material travels on its way to the spinner plate; and, a motor suitable to adjust the size of the aperture and thereby to control the flow of the material onto the spinner plate.
Abstract:
An upright induction chamber (100) is positioned within a melting tank (24) of a snow melting apparatus (20). The melting tank is filled with melting water. Shredded snow from a hopper assembly (22) is introduced into the upper end of the induction chamber along with heated melting water, to be mixed by an impeller fan pump (110) that is operated to force the melting water at sufficient speed through the induction chamber to overcome the buoyancy of the snow, thereby facilitating uniform distribution of the snow across the induction chamber and good mixing of the snow with the melting water. A portion of the liquid composed of the melted snow and melting water from the induction chamber is expelled from the melting tank, and a portion of the liquid from the induction chamber passes through a heat exchanger (34) positioned within the heating tank to be heated thereby and then re-introduced into the upper portion of the induction chamber.
Abstract:
The invention relates to a method for cleaning, clearing, and/or treating an elongate, particularly rectilinear paved path, especially a taxiway and/or take-off runway and/or landing runway of an airfield, said path being used in the longitudinal direction in successive, irregular intervals by starting or landing aircraft. In said method, cleaning or clearing movements in at least one segment of the path are carried out in cycles, at a defined operational width and at an oblique or right angle relative to the longitudinal direction of the path, by two or more identical, successive cleaning or clearing runs and/or movements of at least one clearing apparatus.
Abstract:
A snow thrower is disclosed having a reverse shut-off mechanism configured to deactivate voltage supplied from a power source to a motor that rotates an auger assembly. The reverse shut-off mechanism deactivates the voltage supplied in response to the snow thrower being moved or rolled in a reverse direction. Upon movement of the snow thrower in a forwards direction to clear snow or other debris, the shut-off mechanism reactivates voltage supplied from the power source to the motor that rotates the auger assembly. This allows the snow thrower to conserve power and/or fuel when the snow thrower is not being used to clear snow or other debris.
