A method of manufacturing a pressure vessel includes forming an outer cylinder including an annular wall, positioning an inner cylinder within the outer cylinder, and deforming the annular wall of the outer cylinder to engage a portion of the inner cylinder to retain the inner cylinder within the outer cylinder and form the pressure vessel.

Cylinder assembly for gas spring fastener driver

A gas spring-powered fastener driver includes a cylinder, a moveable piston positioned within the cylinder, and a driver blade attached to the piston and moveable therewith from a retracted position to a driven position to drive a fastener into a workpiece. A fill valve is coupled to the cylinder and operable to selectively fill the cylinder with gas to a pressure.

A method of operating a fastener driver comprises initiating a fastener driving operation by moving a driver blade from a retracted position toward a driven position, and detecting that the driver blade has become jammed in an intermediate position between the retracted position and the driven position. The method further includes moving a latch from a locked position, in which a lifter assembly is maintained in an engaged position by the latch for moving the driver blade from the driven position toward the retracted position, to a released position, in which the lifter assembly is movable away from the driver blade. The method further includes driving a motor to rotate a lifter of the lifting assembly, thereby moving the lifter assembly away from the driver blade, then, returning the lifter assembly to the engaged position, and moving the latch from the released position to the locked position.

Jam release and lifter mechanism for gas spring fastener driver

A fastener driver includes a first nosepiece and a second nosepiece coupled to the first nosepiece with a fastener driving channel formed between the first nosepiece and the second nosepiece. A workpiece contact element is movable with respect to the first nosepiece and the second nosepiece between an extended position and a retracted position. A quick-release latch secures the first nosepiece and the second nosepiece together. The workpiece contact element is positioned between the quick-release latch and the first nosepiece.

Depth of drive adjustment mechanism for gas spring fastener driver

A fastener driver comprises a drive blade movable from a retracted position to an extended, driven position for driving a fastener into a workpiece and a gas spring mechanism for driving the drive blade from the retracted position to the driven position. The gas spring mechanism includes a drive cylinder and a drive piston attached to the drive blade for movement therewith. The drive piston is acted on by a driving force resulting from a pressure differential created by the gas spring mechanism. The fastener driver also includes an adjustable valve for selectively limiting a flow of gas into the drive cylinder above the drive piston, or a flow of ambient air at atmospheric pressure from the drive cylinder beneath the drive piston, thereby changing the pressure differential acting on the drive piston, as the drive piston and the drive blade move from the retracted position to the extended position.

Gas spring fastener driver including shutter valve

A fastener driver comprises a driver blade movable from a retracted position to an extended, driven position for driving a fastener into a workpiece, a gas spring mechanism for driving the driver blade from the retracted position to the driven position, the gas spring mechanism including a storage chamber cylinder containing a pressurized gas, means for determining a pressure in the storage cylinder chamber, and an indicator activated in response to the determined pressure in the storage cylinder chamber being less than a predetermined pressure value.

Control system for gas spring fastener driver

A fastener driver includes a housing, a cylinder disposed within the housing, a piston positioned and movable within the cylinder, a driver blade attached to the piston and movable with the piston, a motor for driving movement of the piston, a battery removably coupled to the housing for supplying power tot the motor, a nosepiece at least partially defining a fastener driving track through which fasteners are driven by the driver blade, and a magazine operable to supply the fasteners to the nosepiece. The magazine is removable from the nosepiece only in response to prior removal of the battery from the housing.

Gas spring fastener driver

A fastener driver includes a main housing, a drive blade movable from a retracted position to a driven position for driving a fastener into a workpiece, and a gas spring mechanism for driving the drive blade from the retracted position to the driven position. The gas spring mechanism includes a piston movable between a retracted position and a driven position. The fastener driver also includes an extensible cylinder for moving the drive blade from the driven position toward the retracted position. The extensible cylinder includes a cylinder housing coupled one of the main housing or the drive blade, and a rod coupled to the other of the main housing or the drive blade. A vacuum is created in the cylinder housing for biasing the drive blade toward the retracted position.

A fastener driver comprises a driver blade movable from a retracted position to a driven position and a lifter assembly for moving the driver blade from the driven position toward the retracted position. The fastener driver also includes a first sensor to detect the driver blade in the driven position, a latch which, in a locked position, maintains the lifter assembly in an engaged position, an actuator coupled to the latch for moving the latch between the locked position and a released position, in which the lifter assembly may move away from the driver blade, and a controller electrically connected with the first sensor and the actuator. In response to an absence of a signal from the first sensor after a predetermined time following initiation of a fastener driving operation, the controller triggers the actuator to move the latch from the locked position to the released position.

Sludge from an anaerobic digester is treated to recover one or more of fibers, or solids or liquids with a high nutrient content. The solids or liquids can be used as a fertilizer. The fibers can be used in a plant growing medium. Solids are separated from liquids in the sludge and dried. The solids may be dried to produce a flake or pellet. Ammonia in the liquids is recovered and used to produce a concentrated acidic ammonium salt solution. This solution may be mixed with the solids to produce a nitrogen enhanced solid. The fibers and solids or liquids can also be used in combination to produce an enhanced plant growing medium. A device and process for removing ammonia from a liquid can be used in the system or separately.

Organics and nutrient recovery from anaerobic digester residues

A system and method for retrofitting a manual benchtop milling machine utilizing servo controls and/or stepper motors, in which a retrofit kit and method for the modification of a milling machine incorporates ball screws and ball nuts, without removing or replacing the original acme nuts, which have been properly configured and aligned to the machine on which they were originally installed. The retrofit kit and method allow for the modification using the alignment of the original acme nuts in their proper location and alignment obviating the need for custom machining or alignment.

Universal retrofit kit apparatus and methods thereof

A tool for removing an interchangeable cooking insert from a grill has a handle end and an engagement end. A handle extends from the handle end toward the engagement end. A support arm extends from the handle toward the engagement end. The support arm has a first lateral edge defining a first lifting hook and a second lateral edge defining a second lifting hook. The first lifting hook and second lifting hook are configured to engage a portion of the cooking insert. A support pin extends across the support arm between the first lateral edge and the second lateral edge. A latch member is pivotally coupled to one of the support arm and the handle. The latch member includes a first end selectively engageable with a portion of the cooking insert and a second end extending through the handle for actuation of the latching member by a user.
