Abstract: A layered blinds device having a series of screens of evenly spaced rods held in parallel relation to one another that allow users to manipulate light penetration and view transparency as independent variables and a method for doing the same. A spacing mechanism adjusts the spacing between the screens which controls the light penetration while an alignment mechanism adjusts the alignment of the rods which controls the view transparency. The blinds can be adjusted manually or by a tracking system.

Abstract: A composite material is provided that includes an array of machine elements disposed within a matrix material. Each machine element includes a cross-section defining an internal space that is filled with a viscous fluid. Preferably, the machine elements are provided in complementary pairs of tubular members, with the internal spaces of the tubular members communicating with one another. When subjected to a predetermined force, the cross-sections of the tubular members change shape, changing the volume of the internal spaces, and causing fluid to flow into or out of the internal spaces. Preferably, under the predetermined force, one tubular member increases in volume and the other tubular member simultaneously decreases in volume, thereby causing fluid to flow between the tubular elements to dissipate energy from the predetermined force.

Abstract: An inverted trolley assembly mounted in an upper channel of a movable wall panel. The inverted trolley includes an elongated trolley carrier having a centrally attached trolley block and a bore at each end to receive the axle of a roller assembly. Each roller assembly includes spacers to center the roller on the axles. The inverted trolley is connectable to a track mounted trolley, preferably by a threaded hole which receives a pendant bolt from the track mounted trolley. The inverted trolley is installed within a channel at the upper end of the wall panel with the rollers engaging the wall panel top frame thus supporting the wall panel. The panel top frame includes a slot through which connection to the track mounted trolley is made. The assembly also includes a trolley retainer which limits the range of motion of the inverted trolley.

Abstract: The present invention 10 discloses a louvered window insert comprising two louvered frame sections 39, 50 each having one vertical member 44, 60 with an upper and lower horizontal member 40, 42, 56, 58 extending from each end thereof and a plurality of louver blades 46, 52 extending horizontally therebetween. The distal ends of the horizontal members and louver blades of the first section have recesses 48, 54 to receive and slidably secure the horizontal members 56, 58 and louver blades 52 of the second section as they travel therethrough allowing a user to size the insert to a window 12 simply by placing the fully overlapped assembly inside an open window 12 and separating the two frame sections 39, 50 thereby reducing the overlap of the horizontal members and the louvers and effectively elongating the insert until the two vertical members 44, 60 are flush to their respective side jambs and then lowering the window 12 until it sits atop the present invention.

Abstract: Pivotably mounted barriers extending across a portion of and staggered in an alternating manner from opposite sides and spaced apart as to permit directed travel up or down stairs or staircase. Barriers extend across staircase to the extent that in addition to acting as an aid in ascending or descending, should a person stumble or lose their footing, their fall would be interupted within a few feet instead of tumbling all the way to the bottom suffering certain injury and possible death.

Abstract: A hangar door assembly for passing the vertical stabilizer of an airplane tail, includes a main door frame fitted into a wall of an aircraft hangar building, a main door pivotally mounted within the main door frame, an auxiliary door frame having a vertical edge, and fitted into the hangar building wall above the main door frame, an auxiliary door pivotally mounted on the vertical edge and biased with a spring to swing to an open position, a bearing assembly attached to the main door bearing against the auxiliary door, to oppose the biasing of the spring to close the auxiliary door when the main door is slid closed. A method for opening an auxiliary door as described above includes the steps of sliding the main door to an open position, thereby gradually moving the bearing assembly toward the vertical edge, keeping the auxiliary door in contact with the bearing assembly as the bearing assembly moves toward the vertical edge with the spring, thereby gradually opening the auxiliary door.

Abstract: A composite array consists of plate-like elements or solid bodies interconnected by endless filaments. The front and rear surfaces of each element are provided with grooves, the grooves being divided in two groups, with grooves of each group running parallel with one another. The filaments lie within the grooves and are not attached to the elements. The filaments are arranged upon the elements so that each filament, upon reaching a lateral side of an element, is led into a groove on the opposite surface of the array. If the lateral side lies at the outmost edge of the array, the grooves are of different direction, while at lateral sides forming a line of contact, the grooves run in the same direction. On one or both surfaces of the elements, markings, numbers, letters, text or pattern elements may be found, for differentiating and determining the elements' positions.

Abstract: An array of plate-like elements is retained by endless filaments looped on the elements to form migrating hinges between individual elements and other elements adjoining same. Grooves are formed in the surfaces of each plate, the grooves being in two groups, with the members of each group being mutually parallel, and the grooves of each surface being in overlying registration. The filaments lie within the grooves in a selected pattern, with filaments forming anchor points at plate sides at which the filament wraps around the side of the plate to enter a groove from the other group of grooves on the opposite side of the plate, and hinge points at plate sides where the filament passes from one plate to an abutting plate, proceeding from one surface to the opposite surface in doing so. Manipulation of the resulting array allows two such plates to rotate mutually about an axis defined by hinge points lying on their abutting sides.

Abstract: An electronic timepiece having a step motor is driven by a drive circuit which selectively produces either continuous hand-carrying pulses or stepwise hand-carrying pulses. The continuous hand-carrying pulses are produced by a continuous hand-carrying waveform shaping circuit connected to a frequency divider, and the stepwise hand-carrying pulses are produced by a stepwise hand-carrying waveform shaping circuit connected to the frequency divider. The selection of either the continuous hand-carrying pulses or the stepwise hand-carrying pulses is executed by a hand-carrying mode selection circuit in response to the operation of a reset switch for resetting the frequency divider.
