Abstract: A locking assembly of a lavatory door in an aircraft, comprising: a locking mechanism; and an occupancy indicator. The occupancy indicator is configured with a display that enables viewing of a status of the lavatory of availability or is occupancy. The position of the locking mechanism and occupancy indicator has been changed from a higher location on the lavatory door that approximates a line-of-sight from a standing position at the lavatory door to a lower location that approximates the line-of-sight from a seated position at the lavatory door. The display of the occupancy indicator is configured with a plurality of display angles to display the status comprising at least a first display angle to allow viewing from the line-of-sight in the standing position and at a second display angle to allow viewing from the line-of-sight in a seated lower position at the lavatory door.

Abstract: In some variations, an interferometric frequency-reference apparatus comprises: an atom source configured to supply neutral atoms; a collimator configured to form a collimated beam of the neutral atoms; one or more probe lasers; and a Doppler laser configured to determine a ground-state population of the neutral atoms. Other variations provide a method of creating a stable frequency reference, comprising: forming a collimated beam of neutral atoms; illuminating the neutral atoms with first and second probe lasers; adjusting the frequencies of the first probe laser and second probe laser using Ramsey spectroscopy to an S?D transition of the neutral atoms; and determining a ground-state population of the neutral atoms with another laser. The interferometric frequency-reference apparatus may provide an optical frequency reference or a microwave frequency reference.

Abstract: A radio frequency (RF) electrical contact includes an electrical contact having a stationary electrical contact member and a movable electrical contact member that is received by the stationary electrical contact member. The movable electrical contact member is movable between an initial position and a mated position. The movable electrical contact member can contact the stationary electrical contact member at a stationary or fixed contact location.

Abstract: The present invention is a tilt truck and related method of transporting a vertical tank utilizing the tilt truck. The tilt truck includes a tractor truck with a tilt platform rotatably connected to a chassis of the tilt truck which can be raised to an angle of more than 90 degrees with respect to the tilt truck. The tilt platform includes a sliding arm assembly with at least one grappler hook sized to receive and secure a tank lifting bar of a vertical tank. The tilt truck, utilizing the tilt platform and sliding arm assembly is capable of lowering a vertical tank from a vertical position to a horizontal position ready for transport by a single operator located within a cab section of the tilt truck. Similarly, the tilt truck can also raise a vertical tank from a horizontal position to a vertical position.

Abstract: Floating roof tank for a volatile liquid have an outer roof and an internal floating roof with a primary seal with a support such that when the tank is empty, the floating roof will rest on the support whether the tank is in a vertical or horizontal position. The support enables the tank to be transported in a horizontal position without damage to the seal. The floating roof tank with support can be configured as a conical tank, flat bottom tank or slant bottom tank. The floating roof tank can also include a cleaning system and a flush mounted manway cover.

Abstract: The present invention is a tank transport system having a hydraulic tilt tank trailer and a vertical tank. The hydraulic tilt tank trailer includes a utility trailer and a tilt chassis having a tilt chassis frame, where tilt chassis is rotatably attached to the utility trailer. A hydraulic lift system is used to provide the mechanical force to tilt, or rotate, the tilt chassis. The vertical tank includes a hollow body supported by a base frame and a sled frame. To load the vertical tank, the vertical tank is positioned to rest on the sled frame and tilt chassis is tilted from the towing position to the loading/unloading position. The vertical tank is pulled onto the tilt chassis where only the sled frame is in contact with the tilt chassis. The tilt chassis is then tilted, or rotated, back into the towing position for transportation.

Abstract: An industrial tank transport system used to transport an industrial tank without the use of a trailer. The industrial tank transport system is comprised of four components; a semi-tractor truck, a removable lift system, a dolly, and a tank. When these four components are combined together, the tank can be transported without the use of a conventional semi-tractor trailer. Various combinations of these four components are used to practice the various methods of raising and lowering the tank between a horizontal position and vertical position using the semi-tractor truck, transporting the dolly using the removable lift system and semi-tractor truck, attaching and removing the removable lift system to the semi-tractor truck, and attaching and removing the dolly to and from the tank using the removable lift system and semi-tractor truck.

Abstract: A collective vertical tank has a plurality of tanks and stabilizing and weight-distributing connectors. The connectors are adjustable to provide an adjustable footprint of the collective tank. A stabilizing and weight-distributing connector for vertical hydraulic tanks includes a first connecting member attached to a first vertical tank and extending away therefrom, and a second connecting member attached to a second vertical tank and extending away therefrom. The second connecting member defines a central passage adapted to receive the first connecting member therein. A locking mechanism secures the first connecting member within the second connecting member.
