  • Patent number: 5855547
    Abstract: A vacuum pump has a bulb whose wall is composed of elastic material and has a first protuberance projecting into the interior of the bulb and a second protuberance projecting outwardly of the bulb. The first protuberance has an air intake passageway for communicating with a chamber that is to be evacuated and the second protuberance has an air exhaust passageway communicating with the interior of the bulb. Each of the protuberances has a slit that is pressed closed by the inherent elasticity of the protuberance material so they serve as check valves. When the bulb is squeezed air pressure developed in the bulb acts on the interior air intake protuberance to close its slit and the slit in the exterior air exhaust protuberance is forced open to exhaust air from the bulb. When the squeezed bulb is relieved the elastic bulb expands to create negative pressure in the bulb which closes the exhaust slit and opens the air intake slit.

  • Patent number: 5826822
    Abstract: A cyclic and collective control system is provided for controlling rotor pitch in a rotary wing aircraft. The rotor blades are pivotally mounted on a hollow, spinning shaft. An angularly and vertically displaceable control shaft is mounted with the spinning shaft and carries a rotatable control hub at its end. The control hub is coupled through pitch link rods to the rotor blades. When the control shaft is displaced vertically within the spinning shaft, the rotor blade pitch is changed collectively. When the control shaft is displaced angularly relative to the spinning shaft, the rotational plane of the control hub becomes skewed relative to the rotor axis. This has the effect of changing the pitch of the rotor blades in accordance with their rotational position around the rotor axis and has the further effect of providing cyclic control.

  • Patent number: 5820083
    Abstract: A tie mounting system for securing elongate items to a supporting structure includes a flexible tie and a mount for anchoring the tie to the supporting structure adjacent a mounting stud. The mount is secured to the stud with a nut and washer and provides an anchoring loop through which the tie can be looped to secure the tie and the items to the mount. The mount extends up and away from the supporting structure to provide clearance for the tie. The trailing end of the mount is rounded and the upper surface of the mount is shaped to conform to the rounded shape of a second, similar mount. This enables two or more of the mounts to be stacked atop one another over the stud. A tab within the mount engages the stud to lightly secure the mount to the stud until the nut and washer can be installed. By using one or more ties having a buckle mount formed adjacent its locking head, two or more ties can be chained together to permit the mounting of two or more separate bundles with a single mount.

  • Patent number: 5799514
    Abstract: A handcuff includes a pair of arcuate cuff bow arranged to encircle a human wrist. A locking mechanism on one of the cuff bows releasably engages the other bow to secure the bows around a wrist. A fluid actuated cylinder coupled to the locking mechanism releases the locking mechanism when pressurized fluid, such as air, is applied. The fluid actuated cylinder avoids the use of keys, resulting in a more enclosed structure that is more difficult to pick than prior key-based mechanisms. Use of the fluid actuated cylinder further improves security by making ordinary handcuff keys, which are frequently possessed by or available to prisoners, ineffective to open the handcuffs.
