    摘要： Systems and methods for providing tube end forming equipment or machines that utilize the advantage of hydraulic power without having the constant noise, heat, and energy usage associated with traditional hydraulic power units. The end forming machine includes a hydraulic pump that is operated only when a demand from the system for oil pressure/flow is present. This is accomplished by providing a synchronous servo motor and servo drive coupled to a fixed displacement hydraulic pump. The oil pressure of the system is monitored to detect when the pressure drops below a preset value to provide closed-loop control of the servo motor. The servo motor is controlled to rotate the hydraulic pump at the required speed (up to the maximum RPM of the motor/pump combination) as necessary to obtain the desired system pressure during the tube end forming process.

    摘要： An apparatus for producing gas for use in medical applications. The apparatus includes a compressed gas unit having at least one container of compressed gas and a solenoid valve. An adjustable pressure regulator communicably connected to the gas container, separate and distinct from the solenoid valve, is adjusted to control the pressure of the gas provided from the container to the solenoid valve. An electrical power source is connected to the solenoid valve. A pressure activated electronic switch connected to the power source is responsive to a selected amount of voluntary fingertip, pressure for opening the solenoid valve to transmit the gas therethrough to a conduit, which further transmits the gas to a destination for use or storage.

    摘要： A key ring including a continuous loop of material including a first section extending for the majority of the circumference of the continuous loop of material having a thickness of D1, and a indented second section extending for the remainder of the circumference of the continuous loop having a thickness D2 less than D1. The key ring also includes a securing device slidable about the continuous loop to cover and uncover the indented second section. One or more spring clips including a moveable arm having a tip end and a fixed member to which the movable arm is attached, the moveable arm moving between an opened position and a closed position, wherein a distance D3 is provided between the tip end of the moveable arm and a hook end of the fixed member when the moveable arm is in the opened position abutting the fixed member. The distance D3 is greater than D2, and less than D1 thus only allowing the spring clip to be attached and removed from the key ring at the indented second section of the continuous loop of material. The spring clip includes a split key ring.
