A method and device for rapidly changing at least one of the temperature and the state of a liquid in a container is provided. The container is rapidly rotated about its longitudinal axis. A source of a thin film of a medium having a different temperature than the liquid in the container is provided to thermally affect the container while rotating the container. The container is positioned at an angle to the horizontal of less than 45°, and the position of the container with respect to the thin film source is controlled by angling the axis of the container skewed from the axis of the rotating mechanism. The device can be used to cool liquids such as beverages, warm liquids such as infant formula, and / or make ice cream.

The invention discloses a fencing post and a fencing system. The fencing post is used for fixedly installing fencing sheet bodies extending along the longitudinal direction and the horizontal direction; the fencing post comprises a first body extending along the longitudinal direction and a second body fixedly connected to the first body; the side of the first body, which is connected with the second body, is provided with a connecting surface on which a plurality of first locating pieces are distributed along the longitudinal direction; a plurality of second locating pieces matched with the first locating pieces are respectively distributed on the second body along the longitudinal direction; one locating piece of the first locating pieces and the second locating pieces is connected with the other locating pieces in a locating way after passing through the sheet bodies; and the sheet bodies are clamped and fixed between the second body and the first body. The fencing post can be used for improving the firmness and the flatness in fixing the fencing sheet bodies and has the advantage of good disassembly and damage preventing effects.

An electrical connector includes an insulating body with a main body portion in which a first receiving space is concavely formed. Spaced first terminal passages extend in a top surface of the first receiving space. A second receiving space is formed in the front end of the main body portion and connected with the first receiving space. A tongue plate extends forwards from a front end face of the main body portion and has a working surface in which spaced second terminal passages extend. The second receiving space is located above the tongue plate. First and second conductive terminals are respectively correspondingly received in the first and the second terminal passages. When a memory card is inserted into the connector, there is no other in-series disturbed signal noise for stable signal transmission; and when the memory card is inserted to its position, it cannot swing and can be connected stably.

The invention relates to a double-acting lift-positioning energy-saving gas stove, and the technical scheme thereof is as follows: at least two outward-tilting bars are evenly arranged at the bottom of a hearth along the circumferential direction and are evenly distributed on the outer edge of a cavity cover; at least two inward-tilting bars are evenly arranged at the bottom of a lift fire tray along the circumferential direction and are evenly distributed on the inner edge of the cavity cover; the outward-tilting bars and the inward-tilting bars correspond to each other in a one-to-one manner and are in matched connection via a tilting plate respectively, the middle part of the tilting part is arranged on the cavity cover in a hinged manner, the outer end of the tilting end props upwardsand supports the outward-tilting bar, the inner end of the tilting plate props upwards and supports the inward-tilting bar, and the hearth and the lift fire tray are lifted relatively; and the lower end of the cavity cover is connected with a diverter, the upper part of the diverter is provided with a gas transmission conduit, the lower part of the lift fire tray is provided with a guide sleeve, and the gas transmission conduit is arranged in the guide sleeve to form a sliding guide pair. The invention has the advantages of simple and reasonable structure, safety, environment protection, energy conservation, no noise in the lift process, manufacturing materials saving and light overall quality, and is suitable for pans in various specifications.
