    摘要: A hydraulic actuated pressure booster unit includes a differential power piston and an integral control valve controlling the pumping direction and action. The control valve has a reciprocally mounted tubular spool member in a cylindrical valve body. The spool member has a control passageway and a plurality of spaced spools, one of which mates with the power piston passage to form a first valve for transfer of oil to the pumping chamber and from a transfer chamber to an exhaust passageway. A pair of spaced spools slide in stepped control chamber forming a control bore and exhaust bore connected by the spool passageway to the pumping chamber via the first valve. A sequence valve connects the exhaust bore to the exhaust through a directional control valve. The sequence valve is controlled by the output working pressure. A pilot valve controls the load connection to the one end of the cylinder and a high pressure relief valve limits the total pressure created within the working system. The valves and operating sections are axially mounted in longitudinal spacing within a tubular housing having fluid passages formed by recesses in the sidewalls and sealed by an outer shell.

    摘要: According to some embodiments, a member authentication request is received at a security server from a client server. The member authentication request may be associated with, for example, a member attempting to access confidential information from the client server. A secure key associated with the member may be determined and data associated with that key may be transmitted to the member (e.g., via his or her wireless device or computer). Secure key information may be received from the member and validated. Based on the validated secure key information, it may be arranged for the member to receive the confidential information from the client server.

    摘要: A body stretching exerciser in which head end and foot end traction units are connected with opposing vertical wall surfaces adjacent a floor and includes flexible bands encircling longitudinally spaced portions of a user's body when supine. A U-shaped member, connected with one wall by a resilient strand, has a strap around the perimeter of its bight portion forming a spreader disposing the end portions of the strap on either side of a user's head when connected with his neck or torso. A hoist or block and tackle, interposed between the other traction unit and the other adjacent wall, exerts a stretching action on the user's muscles and joints in accordance with operation of the hoist by the user of the exerciser.
