Some embodiments of the present disclosure provide an infrared-transmitting housing for preventing light interference and an infrared positioning handle. The infrared-transmitting housing for preventing light interference includes a first housing and a second housing disposed on an outer side of the first housing, wherein the first housing is an infrared-transmitting member and the second housing is a light-shielding member; the second housing is provided with a via corresponding to a position of an infrared lamp of an external device; and the first housing and the second housing are integrally formed by a two-shot injection molding.

Infrared-transmitting housing for preventing light interference and infrared positioning handle

A method for preparing an isocyanate in a gaseous phase by feeding, in the presence or absence of an inert gas, an amine-containing gas stream and a phosgene-containing gas stream into a reaction region, allowing the amine and the phosgene to contact in gaseous forms and undergo a phosgenation reaction in the reaction region, thus preparing the target isocyanate in a gaseous form in the reaction region. The phosgene-containing stream is subjected to preheating and warming before being fed into the reaction region, and the phosgene-containing stream comprises a substance A at a mass fraction of &#x3c;1% before being subjected to the preheating and warming up. Substance A is a NCO group-containing substance and/or an olefinic double bond-containing substance. The method reduces the formation of clogging matter in a heat exchanger and a vessel during the preheating and warming of the phosgene and during the reaction process.

Provided are a cash storage apparatus and a cash recycling and processing device. The cash storage apparatus includes a cabinet and a banknote box assembly. The cabinet is provided with a first inlet/outlet at a top of the cabinet and two guiding parts inside the cabinet. The two guiding parts are arranged in a first direction at an interval. Each guiding part includes a guiding rail extending in a second direction vertical to the first direction. The guiding rail is provided with a locating part. The banknote box assembly is provided with a second inlet/outlet at a top of the banknote box assembly and two first movable parts. The two first movable parts are arranged in movable fit with the two guiding rails respectively.

Cash storage apparatus and cash recycling and processing device

A method for sealing a post-cast strip in a foundation with no gap includes the following steps: mounting steel plates, horizontal pipes and vertical pipes cooperatively layer by layer in a post-cast strip, respectively, such that the upper open end of each vertical pipe protrudes from the ground through the post-cast strip; pouring grout into the post-cast strip from the top of the post-cast strip after the end of the settlement of the foundation, and carrying out high-pressure grouting into the vertical pipe using grouting equipment simultaneously; delivering the sealing grout poured into the vertical pipe to the horizontal pipes, such that the sealing grout overflows from the grout outlets of the horizontal pipes to densely fill up existing gaps; and cutting off the portion of the vertical pipe above the ground after the post-cast strip is completely sealed, and levelling the top of the cut-off vertical pipe with concrete.
