摘要:
Apparatus is provided for controllably delivering liquid, preferably foam producing liquid, from a remote supply tank to a holding tank for replenishment of liquid in the holding tank. The apparatus utilizes a pressurized air source of a vehicle to supply the energy to move the liquid. A liquid level sensing, signaling element is adapted to automatically control the filling of the holding tank and terminating operation when the holding tank is no longer being replenished.
摘要:
A fluid intake pressure regulating system of this invention maintains the pressure of fluid entering a pump below a preselected level for avoiding undesirably high fluid discharge pressure exiting the pump.
摘要:
A pumping system for pumping liquid with entrained intermittent volumes of gasses. The pressure downstream of the pump is measured and the speeds of the engine and pump are controlled in response pressure changes downstream of the pump by a controlling element overriding a governor of the engine.
摘要:
A safety and warning apparatus for attachment to a vehicle. The apparatus includes light bars that are moveable between first and second positions relative to the vehicle and control means for selectively moving the light bars and actuating lights of the light bars.
摘要:
An improved hand cart has an elevator and a power system for controllably moving the elevator between an at rest position adjacent the ground and an elevated position. The hand cart has a pair of wheels for moving the hand cart and any accompanying load along the ground.
摘要:
A water controlling kit is connected to the fluid system, of a fire truck for example, used for pumping water to one or more fire hoses. The kit has a water level gauge, a signaling element and a control valve and is adapted to maintain the pressure at the inlet of the pump of the fire truck within a preselected range of about 1.5 to about 3 psi. during discharge from the pump and pressure fluctuations of the pressurized water supply supplying water to the fire truck reservoir.
摘要:
A portable safety screen is constructed of sight blocking material and supported by spaced apart uprights. A line extends between the uprights and the sight blocking material is connected to the line. The sight blocking material has a plurality of air passage cuts extending therethrough.
摘要:
A covering blanket has a plurality of straps for securing a patient against movement. The straps are of the hook and eye type and are connectable to a back board, stretcher or other apparatus. A stabilizing sheet with stabilizing rods can be connected to the covering blanket and define a means for transporting a patient.
摘要:
A pike pole has a cutting-piercing member connected to one end of the pole. The cutting member normally extends outwardly from the pike pole. The cutting member can be released by a controlling member and be pivotally moveable to a position extending generally along the piercing member.
摘要:
A roof rack system for transporting elongated objects, such as a ladder, on a tall vehicle, such as a fire truck, has first and second supports extending transversely the vehicle. An elevating system is associated with the first support to controllably raise and lower the first support. A restraining system is connected to one of the supports and is adapted to controllably restrain movement of the elongated object relative to the supports and the vehicle. A method of using the apparatus is described.
