Abstract: A safety device that can close the paper passage of a shredder has a touch board pivoted in the vicinity of the shredder opening. When the board is under a pressure produced by fingers touching the opening, it is rotated about its pivotal axis. Its rotation drives a transmission mechanism and a closing element to close the opening. Therefore, the fingers cannot go into the opening and get hurt. Once the pressure on the touch board disappears, a restoring element pushes the touch board back to its normal position and brings the closing element away from the closing position. The opening is thus open again.

Abstract: A control mechanism for the feed of a brush chipper is disclosed. A lower feed stop bar, located under a feed table, pivots on a pivot axis located below and toward the brush chipper from the control bar of the lower feed stop bar. The center of gravity of the lower feed stop bar, then, tends to pivot the lower feed stop bar away from the feed disengage position. Hence, nuisance trips due to vibration, impact of brush on the table, etc., are reduced.

Abstract: The method of precision winding of yarn into packages by frequently changing the wind ratio within one winding cycle solves the problem related to frictional force “Fr”, which is generated in the odd layer at unwinding of packages, by introducing a quite innovative technique of threads winding on the tube in odd winding-on layers and even layers. To carry out the method according to this invention, it does not matter if the driver of thread guides of the winder, on which a package is wound, changes the direction of its rotation or not. If the driver of thread guide, i.e. the servomotor does not change the direction of rotation, it must be taken into consideration that the number of guides should be a multiple of the length of thread guides carriers, and the distance between them should match the length “L” of the package. The thread can be wound on a cylindrical or conical tube, with or without flanges at back end of the package.

Abstract: Disclosed is a printer including a paper feeder for accommodating a rolled paper to be pulled out and recorded thereon. The feeder has a container section to set the roll, in which first and second support walls are arranged to rotatably support the roll. While paper from the roll is taken out, a contact force produced by the roll against the first support wall is kept larger than that in a stationary state, and a contact force produced by the roll against second support wall is kept smaller than that in the stationary state. A friction coefficient between the second support wall and the roll is larger than one between first support wall and the roll, the roll being in slidable contact with the first and second support walls. Therefore, when the recording is started, an impact force to the roll can be alleviated, resulting in reducing unevenness in image in a feeding direction of the paper.

Abstract: An aircraft door mechanism includes a solenoid connected to a support assembly. The solenoid displaces the latch pin between a solenoid energized and a solenoid de-energized position. A catch assembly rotatably connected to the support assembly is positioned to engage a 3½ degree or less taper portion of the latch pin in the solenoid energized position. When the latch pin moves to the solenoid de-energized position, a latch bolt supported by the door rotates the catch assembly. The latch bolt includes a distal bulbous end which multiplies the force applied to the door to rotate the catch assembly. If the latch pin is extended, a substantially greater force is required to force the latch pin to the solenoid de-energized position owing to the reduced taper of the latch pin. Authorized door entry is therefore easier and unauthorized door entry is made more difficult.

Abstract: Systems and methods are disclosed employing electric propulsion stationkeeping in a cyclical manner to better match the cyclical pattern of power generated by the solar array system. For a typical orbit design, e.g. a geostationary orbit, North-South stationkeeping can be intermittently suspended, tolerating some additional drift but yielding in a very significant reduction in the required solar power system. If necessary, stationkeeping can be supplemented with a chemical thrusters during off periods for the electric propulsion. Because of this, the overall electrical power margin for the solar array system design can be reduced without compromising the mission performance.
