Abstract:
A valve device has a valve housing (10), in which fluid ports (P, A, T) are provided and in which at least one valve piston (12, 14) can be moved longitudinally. The valve piston either separates at least two of the fluid ports (P, A, T) from one another or interconnects them as a function of its travel position. At least one latching device (16, 18) is provided for each valve piston (12, 14) for the detachable fastening of the respective valve pistons (12, 14) in one of its travel positions. Each latching device has at least one latching means (20), which can be brought into a latching position (22). As part of the respective latching devices (16, 18) for detachably fastening the respective valve pistons (12, 14), at least one control body (24) t can be moved independently of the respective valve pistons (12, 14), which control body is set up such that, in at least one blocking position, it prevents the relevant latching means (20) disposed in the latching position (22) from leaving the latching position (22) by blocking the latching means (20).
Abstract:
A method and toolset capable of remotely moving a rotor of an implanted device in a first arcuate direction and detecting a first limit of travel, moving the rotor in a second, opposite direction and detecting a second limit of travel without altering the current performance setting of the implanted device, comparing the first and second limits of travel with known values for a plurality of selectable performance settings, and indicating the current performance setting of the implanted device.
Abstract:
A valve actuator for a valve has an electric motor which comprises a rotor and a stator, and further a magnetic detent brake with at least one detent magnet for holding the rotor in a detent position. The least one rotor magnet is arranged on the rotor and co-operates with the detent brake.
Abstract:
A novel collection device for collection, storage and disposal of biological products, in conjunction with an improved cleansing method. Disclosed is an apparatus which includes a locking closing member handle to allow for safe transport and disposal of medical waste. Closing member allows for secure containment of medical waste and subsequent apparatus cleaning. Closing member design includes a gap between closing member and housing which facilitates device cleaning after waste disposal.
Abstract:
A locking device for securing a structure comprising an inner body having an inner surface for attachment to the structure, an outer cover located circumferentially about the inner body, the outer cover freely rotating around the inner body in its securing configuration and a key for insertion into an opening in the outer body. First and second magnets are located in spaced apart first and second cavities within the key such that the magnets are oriented with the south pole of the first magnet and the north pole of the second magnet facing in the same direction. The magnets act on a pin within the body of the lock such that, in a first embodiment, when the key is removed from the lock body the pin is magnetically held away from contact with the inner body resulting in a free turning, locked configuration. When the key is inserted into the locking device the pin relocates to a second position causing the inner and outer body to move simultaneously so that rotational force applied to the outer cover is transmitted to the inner body placing the locking device in an unlocked configuration.
Abstract:
The protective cover assembly comprises a mounting member (4) adapted for tight association with the actuation port and a protective cover unit (2). The protective cover unit is adapted for engagement with the mounting member in a manner such that protective cover unit covers the valve and blocks access thereto. Housed in the cover unit is locking mechanism that comprises a solenoid (62) for driving a locking unit (72) between a locking state in which the cover unit is locked to the mounting member and an unlocking state, in which the cover unit can disengage form the mounting member, and comprises an electronic controller linked thereto, the electronic controller being responsive to an external control signal to actuate the solenoid to drive said locking unit (64).
Abstract:
A device is provided, designed to prevent unauthorized operation of fire hydrants by completely concealing the hydrant operating nut and weather shield within freely rotating sleeves, thereby rendering the hydrant inoperable. The hydrant is made operable by the use of a specially designed self-contained magnetic operating wrench. The hydrant again becomes inoperable when the magnetic wrench is disengaged. The device is externally mounted for easy, quick field installation with common tools, and requires no modification of the internal hydrant mechanism. The device is designed to be used on all hydrant makes and models having an operating nut extending vertically above the hydrant bonnet.
Abstract:
A bistable, electromagnetically-actuated valve has a closed chamber containing a moving armature with a valve orifice in each end of the closed chamber, one of which is formed by the end of a tube, a space around the tube forming the third fluid connection to the closed chamber. The armature has valve seats for closing the valve orifices.
Abstract:
A damper, normally biased closed, in a flue of a heating system has an arm which is connected by linkage to an armature of a solenoid for opening the damper when a winding of the solenoid is energized by a heating system control. Switch means, engaged by the arm, is interposed between the heating system control and burner facilities of the heating system for preventing operation of the burner facilities when the damper is closed and for allowing operation of the burner facilities when the damper is open.
Abstract:
The trip mechanism for operating the turbine trip valve to closed position includes an actuating lever mounted at one end for movement about a fixed pivot and being provided at the opposite end with a cam block. Spring means or the like acts upon the actuating lever to move the cam block into engagement with the trip valve restraining member to move it out of restraining position for closure of the trip valve. A latch is provided for latching the actuating lever against such pivotal movement. The latch is moved out of latching position by means, such as a solenoid, responsive to a signal indicative of an abnormal situation detrimental to the operation of the turbine.
