Abstract: At the input of this matrix a set of transmitters (E1, 1...Em, n) receives information to be transmitted through it. It transmits waves carrying this information, on controlled wavelengths. A set of filters (F1, 1...Fn, m) transmits these waves at the output of the matrix selectively according to their wavelengths. From these transmitters to these filters, these waves are transmitted first of all by a group of switching distributors (X1...Xm) each able to connect each of its inputs to each of its outputs, on command, then by a group of star-wired distributors (C1...Cn) each permanently connecting all its inputs to all its outputs. This invention finds an application especially in a telecommunications network when an information collection operation has to be able to be carried out simply.

Abstract: The control system consists of a gear lever which can be moved through a gate to give automatic and manual control positions - a first stable position (1) for forward drive, and two unstable positions (2, 3). The first unstable position provides for moving away in automatic and manual modes and for changing to lower gears in manual mode, while the second unstable position (3) is used solely for changing to higher gears in the manual mode. The first and second unstable positions are engaged by moving the gear lever forwards and backwards respectively. The vehicle engine can be started only when the gear lever is moved to a second, neutral stable position (4) located to the right of the first stable position, and a third stable position (6) for reverse gear is reached by moving the gear lever backwards from neutral. A variant has a fourth stable position for parking, located in front of the third stable position.

Inventor: SHANDONG YANG
IPC: A01K5/01
Filed: 2020-08-25
Granted: 2022-07-26
Abstract: The present invention provides a livestock feeding device capable of reducing waste and facilitating residual feed collection. In the present invention, a feeding trough is carried on a horizontal rotating shaft that is higher than 5 an arc axis of the feeding trough. Tension springs are added to a lower end of the feeding trough. When the feeding trough rotates under the push of livestock, the feeding trough can immediately return due to its gravity and a pulling force of the springs, so as to prevent the feed from being spilled. 10 In addition, an inner wall of the feeding trough is provided with an array of protrusions, which improve the contact between the residual feed and outside air to a certain extent, and relive the adhesion of the feed. A closable discharge port is added on a bottom surface of the feeding trough, and 15 an auger is provided at a lower end of the discharge port. When it is necessary to clean the feeding trough, the residual feed is manually swept to the auger, and then the auger is turned on to push the residual feed to the outside, which facilitates the cleaning work. The present invention 20 effectively overcomes the operational defects of feeding troughs and has good operational effects.

Inventor: XIAOFEI LI
IPC: B64D15/00
Filed: 2021-10-29
Granted: 2023-05-31
Abstract: The present disclosure discloses a method for realizing anti—icing of an aircraft surface by lubricating with a magneto—sensitive porous anti—icing composite material, comprising uniformly mixing a mixture of a polydimethylsiloxane prepolymer and a curing agent with toluene, saccharides, a magnetic nanoparticle and dimethicone, then drying and curing to obtain a precursor of the magneto—sensitive porous anti—icing composite material; performing solvent exchange of the precursor with an aqueous ethanol solution repeatedly, and then drying to obtain the magneto—sensitive porous anti—icing composite material; adhering the magneto—sensitive porous anti—icing composite material on a target surface via an adhesive; after the adhesive is completely cured, adding a magnetic fluid on a surface of the magneto—sensitive porous anti— icing composite material until that adsorption is saturated, to obtain an aircraft anti—icing surface lubricated by the magneto— sensitive porous anti—icing composite material. The present disclosure uses the sugar templating method to uniformly disperse the magnetic nanoparticle in polydimethylsiloxane with good elasticity, hydrophobicity, lipophilicity and chemical stability, and obtain a highly porous structure at the same time. Thus, the magneto—sensitive porous anti—icing composite material with extremely low ice adhesion strength, long anti—icing life, fast— repairable property, and magnetic response characteristic is prepared, which can help to prevent the aircraft from icing after coated on the aircraft surface.
