Lowerable baggage compartment for a passenger cabin
InactiveUS6484969B2Raised and loweredManual operationAir-treatment apparatus arrangementsFuselagesCouplingEngineering
A baggage storage system especially for an aircraft passenger cabin includes a lowerable baggage compartment, a guide arrangement along which the motion of the baggage compartment is guided between an upper closed position and a lower open position, a powered drive unit, and a coupling arrangement that selectively couples or decouples the drive unit relative to the baggage compartment. With the drive unit coupled to the baggage compartment, a full powered raising and lowering of the baggage compartment is achieved. If the drive unit fails, it is decoupled from the baggage compartment, so that the baggage compartment can be manually raised and lowered. A locking latch arrangement securely latches the baggage compartment in the upper closed position.

Substrate flat grinding device
InactiveUS20090203299A1Superior flat thickness distributionImprove rigidityEdge grinding machinesPolishing machinesKinematic couplingEngineering
To provide a high-rigidity flat grinding device, a substrate flat grinding device has three fastening plate lifting-and-lowering mechanisms that have kinematic couplings and a cylinder rod that move the fastening plate upward or downward. Being a high-rigidity grinding device in which the load of the fastening plate 6 also is a load on the grindstone 14 that does the grinding, there is little deflection in the thickness distribution of the substrates that are obtained, even if they are semiconductor substrates having a large substrate diameter of 450 mm.

Motorized lift device
InactiveUS20050045077A1Minimize chatterMaximizing sliding contactLifting devicesSoil-shifting machines/dredgersLinear motionCoupling
A motorized lift device facilitating the uninterrupted and nearly noiseless movement of a low-profile television. The motorized lift comprises a base unit having a support unit slidably disposed thereon in a vertically-oriented and telescoping fashion. Support unit movement is controlled via a motor directly coupled to a transmission which is coupled to a screw. Coupling between screw and an elevator plate converts screw rotation to linear motion within the support unit. A low-friction floating nut between elevator plate and screw, as well as several low-friction couplings between base unit and support unit reduce noise, wobbling, eliminate binding, and accommodates for misalignments during movement. The support unit accommodates for vertical and horizontal adjustability during mounting and installation of any size low-profile television.

Window Shade Having a Resistance Balancing Mechanism
InactiveUS20130032300A1Easy to adjustAccurately heldExtensible doors/windowsCurtain accessoriesEngineeringTorsion spring
A window shade comprises first and second rails, and a shading structure and a suspension cord connected between the first and second rails. The second rail includes a resistance balancing unit and a cord winding unit to which the suspension cord respectively connects. The resistance balancing unit comprises a housing having an abuttal surface, a pulley pivotally connected with the housing, and a torsion spring. The pulley has a winding portion around which the suspension cord is wrapped, and a shaft portion extending coaxial to the winding portion from a side thereof. The torsion spring is tightly mounted around the shaft portion and has at least one end. The pulley when rotating in one direction drives the end of the torsion spring to push against the abuttal surface of the housing, whereby the torsion spring loosens to allow rotation of the pulley relative to the torsion spring.

InactiveUS20050077017A1Minimal deflectionHighly versatileScreensStage arrangementsControl systemEngineering
A release device for vertically adjustable barriers (theatrical curtains, advertising banners, sun control systems, environment altering systems, acoustic control systems or scenic back drops, etc.), with a support assembly (e.g., roll assembly) with first and second roll supporting frame structures and a tensioner extending between the frame structures. The tensioner can be a cable extending parallel to the roll's axis of rotation. The tensioner compensates for gravity induced sagging of the roll (e.g., a multi-sectional roll). The frame structures are suspended with suspension lines that extend down from an overhanging mount and the frames compress the ends of the roll and negate sag in intermediate area of roll. The roll is supported by bearing sets on the frame structures.

Shutter-like covering and hardware for architectural opening
InactiveUS6901988B2Raised and loweredEasy to modifyVentilation arrangementLight protection screensWindow shutterCentroid
A modular shutter blind system for a window blind application. A window blind is made to look like a window shutter by having airfoil shaped slats which traverse in toward the window when the blind is tilted closed and traverse away from the window and toward the room when the blind is tilted open in order to give the blind the clearance needed to tilt open while making it appear as if the window frame is the shutter blind frame. This traverse motion of the slats is accomplished by having the tilting axis along the centroid of the head rail move in and out while the blind is tilted closed or open respectively.

In one embodiment, a manually operated internal Venetian blind for raising / lowering a plurality of slats is disclosed, and comprises a stationary bearing housing, a longitudinally displaceable bifurcated bearing block, a counterweight interconnected to the bearing block and housing at least one internal magnet, and a first linearly displaceable actuator disposed outwardly to one of two glass sheets and provided with at least one external magnet at a fixed distance from the internal magnet. The displacement of the first actuator is significantly less than the displacement of the longitudinally lowest slat due to the winding of central cords around a ball bearing housed within the bearing block. In another embodiment, a device for tilting the slats to which two outer cords are affixed is provided with two laterally oriented sides and an annular protrusion rotatably supported by a suitable assembly secured to a support surface and transversally extending outwardly from each laterally oriented side, such that the tilting device is rotatable about a transversal axis coincident with the axis of the annular protrusions.
