Abstract: A fastener driver includes a cylinder, a moveable piston positioned within the cylinder, and a driver blade attached to the piston and movable therewith between a top-dead-center (TDC) position and a bottom-dead-center (BDC) position. A lifter is operable to move the driver blade from the BDC position toward the TDC position. A transmission is provided for providing torque to the lifter. The lifter includes a hub and a plurality of lugs extending therefrom. Each lug is engageable with the driver blade when moving the driver blade from the BDC position toward the TDC position. The hub and the lugs are integrally formed as a single piece. The lifter includes a first side and an opposite second side. Each of the first side and the second side is flat.

Abstract: A fastener driver includes an outer cylinder having a cylindrical first end and an opposite, second end, an inner cylinder positioned within the outer cylinder, a moveable piston positioned within the inner cylinder, and a driver blade attached to the piston and movable therewith between a top-dead-center position and a bottom-dead-center position along a drive axis. The outer cylinder defining a longitudinal axis and a storage chamber configured to be filled with pressurized gas. The inner cylinder being in communication with the pressurized gas within the storage chamber. A frame has first end adjacent the cylindrical first end of the outer cylinder and a second end extending outward from the cylindrical first end of the outer cylinder in the direction of the longitudinal axis. The frame is integrally formed with the outer cylinder as a single piece and a nosepiece supported by the frame.

Abstract: A surgical stapler includes a first stapler half including an anvil surface having a plurality of staple forming pockets, and a second stapler half configured to releasably couple with the first stapler half. The second stapler half is operable to deploy staples toward the anvil surface. The stapler also includes a projection positioned on one of the stapler halves and extending laterally relative to a longitudinal axis of the stapler. The stapler halves are configured to pivot relative to each other about the projection. The stapler further includes a locking member positioned on the other of the stapler halves. The locking member is configured to translate along the longitudinal axis of the stapler between a locked state in which the locking member selectively captures the projection and an unlocked state in which the locking member selectively releases the projection. The locking member is biased proximally toward the locked state.

Abstract: An air actuated finger pull back chuck device having a locating portion and a clamping portion. Locator slides and locator cams are air actuated to position the workpiece. The workpiece is located to the device with locator slides and air actuated clamp arms operate clamp fingers to pull back and hold a workpiece to the chuck device for the operation. The locator cams have a single connector to the locator actuator plate and the locator cams can be quickly reversed for locating on an inside diameter or an outside diameter. Various fingers can be attached to the clamp arm to fit various workpiece sizes. The quick change over times for different sized and shaped workpieces are facilitated by the simplicity of the invention.

Abstract: An anti-lock (ABS) hydraulic braking system for vehicles comprises a first normally open solenoid-controlled valve (4) disposed in a line between a master cylinder (3) and a brake (1), a second normally closed solenoid-controlled valve (8) disposed between the brake and expander chamber (7), and a normally-open solenoid-controlled by-pass valve (5) located between the master cylinder and the brake and by-passing the first solenoid-controlled valve (4).

Abstract: A braking system for a vehicle having primary and secondary braking circuits includes a secondary braking circuit having a secondary source of braking pressure connectable to a braking actuator and including a three-port, two-position, inlet solenoid valve having two inlet ports and one outlet port. One of the inlet ports is connected to an outlet of an inlet solenoid valve of the primary braking circuit and to the inlet of an exhaust solenoid valve of the primary braking circuit. The other inlet is connected to a secondary source of braking pressure. The outlet port is connected to the braking actuator. The inlet solenoid valve is movable by an output signal from an electronic control unit.

Abstract: In an anti-lock braking system incorporating a solenoid-operated fluid flow control valve, the rate at which fluid can normally be dumped to release a brake is increased by the provision of a pilot valve. The pilot valve is adapted to open by a pressure drop across a diaphragm. The pressure drop is established when an exhaust valve opens upon energization of the solenoid in response to an anti-lock signal.
