Abstract: 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.

Abstract: Adapters and methods are provided for utilization on a powered two armed rescue tool for opening metal doors. The adapter has a first end portion of general “U” configuration which is hooked over a door. The adapter is connected to one arm of the powered rescue tool and the other arm is positioned in contact with the frame of the door. The powered rescue tool is then actuated which causes the arms to separate and force the door open.

Abstract: A bridle system for a hose has apparatus for connecting the system to a hose, a loop for securing the apparatus and associated hose to a fire truck for example and a loop for assisting in unloading the hose from the truck.

Abstract: 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.

Abstract: 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.

Abstract: The pressure downstream of a pump is measured and the speeds of the engine and pump are controlled in response to pressure changes downstream of the pump by a controlling element overriding a governor of the engine. The speed of the engine and the pump are connected to and controlled by an engine governor.

Abstract: A telescopically moveable support member has a work element connected to a first end thereof. A rail and slotted collar arrangement is associated with the support member and bumpers are connected to the work element to prevent damage to both the work element and vehicle to which connected during movement from the extended position to the retracted position.

Abstract: A manual throttling system for electronically controlling the speed (RPM) of an engine from a remote location relative to the primary engine controls. The engine controlling signals are responsive to rotational speed and direction of rotation of a manual control knob and the frequency of light pulses of an optical encoder.

Abstract: A mechanical cleaning system for transparent material has a separate element on each side of the transparent material and adjacent one another. At least one of the elements is a magnet and the other element is a metal. At least one of the elements has a cleaning material between its respective element and the transparent material. Movement of one of the elements moves the other element and cleans a surface of the transparent material. In the preferred embodiment where cleaning material is on both of the elements, both of the opposed surfaces of the transparent material are simultaneously cleaned by urging one of the elements across the transparent material.

Abstract: The apparatus of this invention has a handle connected to first and second spaced apart spray tubes which are rotatable for passing fluid sprays toward one another or in a common direction outwardly from the apparatus. The handle is connectable to a pressurized fluid source. The apparatus is adapted to decontaminate or clean articles passed between the spray bars and clean articles adjacent the apparatus.
