Pressure cycle operated apparatus and methods. A method of actuating a firing head includes the steps of: reciprocably displacing an actuator piston of the firing head, the displacing step including the piston being alternately pressure balanced and unbalanced; and igniting a combustible material in response to the piston displacing step. A method of generating electricity includes: reciprocably displacing a piston, the displacing step including the piston being alternately pressure balanced and unbalanced; and generating electricity in response to the piston displacing step. A firing head includes an actuator piston separating at least two chambers; a check valve which permits one-way flow between the chambers; a flow restrictor which restricts flow between the chambers; a biasing device which biases the piston toward one of the chambers; and a firing pin releasing device which releases a firing pin in response to displacement of the piston.

A system can include multiple explosive assemblies, each assembly comprising an outer housing, an explosive component rotatable relative to the housing, and a selective firing module which causes detonation of the component in response to a predetermined signal. A method can include assembling multiple explosive assemblies at a location remote from a well, installing a selective firing module, an electrical detonator and an explosive component in a connector, and connecting the connector to an outer housing, and then transporting the assemblies from the remote location to the well. A well perforating method can include assembling multiple perforating guns, each gun comprising a gun body, a perforating charge, and a selective firing module which causes detonation of the charge in response to a predetermined signal. The guns are installed in a wellbore, with the charge of each gun rotating relative to the respective gun body.

A method and apparatus are presented for actuating a differential pressure firing head to actuate a perforating gun at a downhole location in a subterranean wellbore adjacent a formation. An exemplary method includes positioning the perforating gun and the differential pressure firing head at a downhole location on a tubing string and then communicating an applied fluid pressure to a wellbore annulus, a first chamber which communicates the applied fluid pressure to a low-pressure side of the firing head assembly, and a second fluid chamber which communicates the applied fluid pressure to a high-pressure side of the firing head assembly. The applied fluid pressure is then trapped within the second fluid chamber. When the applied pressure in the annulus is subsequently removed, a pressure differential is created across the firing head by the low pressure in the first chamber and the trapped applied pressure in the second chamber.

Apparatus for improving the mixing or blending of the charge of fuel and air to an internal combustion engine and for increasing the quantity of the fuel-air charge to the engine. A rotor member, having a sealing blade and at least one blade member which is angled with respect to a radial reference through the axis of the rotor, is rotated in a housing to draw a portion of the fuel-air charge from a carburetor, to increase the quantity of that portion, to create turbulence in the flow of the fuel-air mixture and to more thoroughly blend the fuel with the air before the mixture is delivered to the cylinder intake of an internal combustion engine.
