Cutting mechanism for carbon nanotube yarns, tapes, sheets and polymer composites thereof
ActiveUS20170129182A1Easy to cutRobust cutting method3D object support structuresManufacturing data aquisition/processingPower flowCarbon nanotube yarn
A cutting mechanism includes electrodes that are utilized to cut or score a non-conductive outer material of a filament or sheet. The electrodes contact a conductive reinforcing material of the filament or sheet to complete an electric circuit. Electric current flows through and heats the conductive material to oxidize or otherwise separate / cut the conductive material and any remaining non-conductive material.

7FAstage 1 abradable coatings and method for making same
InactiveUS20050003172A1Minimal wearReduce gas leakageMolten spray coatingEngine manufactureLeading edgeGrid pattern
A method of applying a profiled abradable coating onto a substrate in which an abradable ceramic coating composition is applied to a metal substrate using one or more coating application techniques to produce a defined ceramic pattern without requiring a separate web or grid to be brazed onto the substrate. The invention is particularly designed to withstand the higher operating temperatures encountered with the stage 1 section of 7FA+e gas turbines to allow for increased coating life without significant deterioration in structural or functional integrity. Typically, the grid pattern coating begins approximately 0.431″ after the leading edge of the shroud, and ends approximately 1.60″ before the trailing edge of the shroud. In the case of diamond-shaped patterns, the grid pattern will be about 0.28″ long and 0.28″ wide, with an overall thickness of about 0.46.″ The coatings thus provide the required levels of abradability and leakage performance and may be applied as a chevron or diamond pattern with the shape oriented such that the diagonals run perpendicular and parallel to the sides of the shroud.

Dual Panel Window Shade Apparatus with Improved Bottom Weight Bar and Rail
InactiveUS20120043029A1Minimal wearShutters/ movable grillesLight protection screensLight transmissionSurface plate
A dual panel adjustable light transmission shade apparatus for adjusting the amount of light passing through a window comprises a spool rotatably mounted in a canopy, and an opening in the canopy. A single piece of material forms opposed facing front and rear panels, and a bight is formed at the bottom of the panels. An upper portion of each panel is fastened to the spool at spaced apart locations on the outer surface of the spool. One of the panels moves generally vertically upward and the other panel moves generally vertically downward when the spool is rotated in one direction. A weight bar is lodged in the bight at the bottom of the panels to apply a downward force on the panels, and the weight bar rotates in the bight only when the panels are adjusted relative to each other.

Spinal rod translation device
InactiveUS20100262190A1Reduce wearAvoid clamping forceSuture equipmentsInternal osteosythesisCompression memberIliac screw
A rod translation device is described that minimizes the wear between a spinal rod and a bone anchor in a spinal implant. In one embodiment, the rod translation device is a sleeve that is slid onto the outside diameter of the spinal rod. At least one compressible member, such as an O-ring, may be placed within the inside diameter of the sleeve to prevent direct contact of the outside diameter of the spinal rod to the inside diameter of the sleeve. Once the spinal rod is secured within the implant any translation of the spinal rod decreases wear debris between the outside diameter of the spinal rod and the pedicle screw.

Valve with end position switching
InactiveUS20060272712A1Avoid destructionImprove sealingOperating means/releasing devices for valvesPipeline systemsEngineeringTappet
For detecting closing or opening of a valve activated preferably by a solenoid actuator, a switch activated by a tappet spring mounted on an armature of the actuator is provided. A stop and an associated surface limit the stroke of the tappet with reference to the switch. Preferably, a valve closing element opens the gas flow only when the armature has already executed a part of its opening stroke. The trigger point of the switch is set in this first part of the opening stroke of the armature, in which the valve closing element has not yet opened. The stroke limiting of the tappet for activating the switch is also preferably set in this region of the opening stroke of the armature. However, the stop limits the stroke of the tappet independent of the opening stroke size of the armature, so that the same switch can be used for different valves with different nominal diameters and opening strokes.

Differential steering application for trailer spotter vehicles
InactiveUS20060207822A1Reduce the overall diameterMinimal effortVehicle seatsVehicle mounted steering controlsVehicle frameHydraulic pump
A trailer spotter vehicle having a seat and a control console which are relatively rotatable with respect to the vehicle frame, and a differential drive system which permits the vehicle to turn within a very small turning radius. The rotatable seat and control console allow the operator to steer the vehicle without having to substantially turn their body or use mirrors to observe the path of the vehicle. To drive the vehicle in a forward direction, hydraulic pumps transmit pressurized hydraulic fluid to the trailer spotter wheels to rotate them in a first direction. In order to drive the vehicle in reverse, the flow of hydraulic fluid to the wheels is reversed to rotate the wheels in an opposite direction. To pivot the vehicle, the first wheel is driven in the first direction and the second wheel is driven in the opposite direction.

Method and control system for compensating for friction
InactiveUS6285913B1Reduce impactMinimal wearProgramme controlOperating means/releasing devices for valvesControl systemControl signal
A method for compensating for static friction in an actuating device includes the steps of generating an actual signal y2(t) corresponding to a quantity which is controllable by the actuating device, generating a set value signal y1(t) generating a control signal s1(t) based on the set value signal y1(t) and the actual value signal y2(t), and supplying the control signal to the actuating device for controlling the same. The method also includes the steps of generating an intermittent signal s2(t) compensating for friction, sensing the sign of the derivative with respect to time of the control signal s1(t), giving the signal s2(t) compensating for friction the same sign as the derivative, and adding the signal s2(t) compensating for friction to the control signal s1(t) before supplying the same to the actuating device.

High temperature abradable coating for turbine shrouds without bucket tipping
InactiveUS6660405B2Reduce gas leakageImprove turbine efficiencyLiquid surface applicatorsMolten spray coatingPolyesterPorous coating
An abradable coating composition for use on shrouds in gas turbine engines (or other hot gas path metal components exposed to high temperatures) containing an initial porous coating phase created by adding a "fugitive polymer" (such as polyester or polyimide) to the base metal alloy, together with a brittle intermetallic phase such as .beta.-NiAl that serves to increase the brittle nature of the metal matrix, thereby increasing the abradability of the coating at elevated temperatures, and to improve the oxidation resistance of the coating at elevated temperatures. Coatings having about 12 wt % polyester has been found to exhibit excellent abradability for applications involving turbine shroud coatings. An abradable coating thickness in the range of between 40 and 60 ml provides the best performance for turbine shrouds exposed to gas temperatures between 1380.degree. F. and 1850.degree. F. Abradable coatings in accordance with the invention can be used for new metal components or to repair existing equipment.
