A package comprising a container body 1 in which liquid contents 3 are accommodated such that a headspace 7 remains, wherein the package is characterized in that: protrusions and recesses are formed along the entirety of an inner surface 1a of the container body 1; the inner surface 1a of the container body 1 comprising the protrusions and recesses is covered by a lubricating liquid 30 that is immiscible with the liquid contents 3; a covering layer of the lubricating liquid 30 is interposed between the inner surface 1a and the liquid contents 3; and, with the container body 1 being held erect,a reservoir 31 of the lubricating liquid 30 that forms the covering layer is formed at a peripheral edge part of the upper-end surface of the liquid contents 3 accommodated within the container body1.

The invention relates to a sealing arrangement (30) for sealing a corner region (31) of a window (18) against a body part (16) of a motor vehicle (10). The sealing arrangement (30) defines a sealing plane (29) and a first sealing axis (24) and a second sealing axis (28) extending transversely to the first sealing axis. The sealing arrangement has a fastening section (36) for fastening to the bodypart (16) and a sealing section (34), which has a sealing lip (40) which can be elastically deflected transversely to the sealing plane (29) when the corner region (31) of the window (18) comes to bear against the sealing lip (40) and which extends in an arcuate manner from the first sealing axis (24) to the second sealing axis (28). The sealing lip (40) is in the form of a cast sealing lip (40) over the entire arcuate extension thereof.

The invention relates to the technical field of building additives, in particular to a preparation method of modified starch ether for improving the sliding performance of tile adhesives. The preparation method comprises the steps of carrying out one-step etherification chemical treatment modification on starch to obtain starch ether, and continuing physical modification treatment. This preparation method has changed the cumbersome operation of multi-step etherification in the preparation of existing modified starch ethers. Only one step of simultaneous etherification can obtain starch ether modified products with better performance, and because the physical modification steps continue to be added, The obtained product can significantly improve the sliding performance when used in tile adhesives; at the same time, the operating conditions of one-step simultaneous etherification treatment are significantly different from those of the prior art.

The invention belongs to the technical field of a measuring device and relates to a hydraulic pendulum bob force measuring mechanism used for detecting pressure strength of a cement test block. The force measuring mechanism comprises an upper box body, wherein a pendulum rod shaft is rotatably arranged on the upper box body, a front end of the pendulum rod shaft penetrates through an outer side of the upper box body, a shaft diameter is fixed with a pendulum rod flange seat, a pendulum rod is fixed on the pendulum rod flange seat through a fastening bolt, the pendulum rod shaft is arranged on a shaft in the upper box body and is fixedly connected with a pendulum rod shaft seat through a taper bolt, two ends of a connection rod shaft are rotatably arranged on the pendulum rod shaft seat through a bearing respectively, two ends of an outer side of the connection rod shaft corresponding to the pendulum rod shaft seat are respectively provided with a pull board, each pull board is respectively arranged along a length direction of the upper box body and penetrates through the outer side of the upper box body, and end portions of the pull boards which penetrate through the outer side of the upper box body are fixed with the pendulum rod shaft seat. Through the force measuring mechanism, a largest force is enabled to change according to weight change of a pendulum bob, the force measuring mechanism is converted to a load indication mechanism through calculation to acquire a measurement result, and an upper limit of measurement can reach above kilotons.
