Abstract: The invention relates to the technical field of spraying bottles with bottoms filled with liquid, in particular to a compact liquid spraying bottle with a bottom filled with liquid. The compact liquid spraying bottle comprises a spraying head, a bottle body and a liquid filling and exhaust function assembly arranged at the bottom of the bottle body, wherein the liquid filling and exhaust function assembly comprises a valve core, a valve bush, a valve seat and a tail cover which are matched jointly to realize liquid filling and exhaust functions. The liquid filling and exhaust function assembly of the invention has a relatively good sealing property on the whole and a relatively compact structure, so that the occupied space of a function area is reduced, the containing space of effective liquid is increased, and the degree of satisfaction of customer use is improved.

Abstract: A method, system, apparatus, and computer program products provides the ability to dynamically define and generate inlet spacing along a road in a building information model (BIM) computer aided design (CAD) three dimensional (3D) model. A representation of a road is acquired in the BIM CAD 3D model, wherein the representation includes a geometry. An inlet spacing is defined for the road. Inlet locations for inlets are determined based on the inlet spacing. A determination is made regarding whether the inlet spacing and inlets satisfy design rules for the road. When the inlet spacing and/or inlets fail to satisfy the design rules, a different inlet spacing is selected from a group of preset integers, and the process repeats until the design rules are satisfied.

Abstract: A method, system, apparatus, and computer program product provide the ability to design a drainage pipe solution. A profile of a surface segment (that includes a surface slope) is acquired. A first pipe size and a first pipe slope or calculated based on a proper velocity. A second pipe size and a second pipe slope are calculated based on the surface slope. A first pipe covering and a second pipe covering for the first pipe size and the second pipe size, for the surface segment is computed. A lower of the first pipe covering and the second pipe covering is selected as the drainage pipe solution.

Abstract: A method of manufacturing an arc corner connecting rib of a metal box shell is disclosed. The method of manufacturing comprises the following steps: preparing a rectangular metal shell whose vertex corner portions are arc corner transition portions; drawing for a first time by means of a first metal drawing mold a top face plate of the rectangular metal shell, so that a plurality of first convex strips are formed in a first area between the two arc corner transition portions of the top face plate; and drawing for a second time by means of a second metal drawing mold a side face plate and the arc corner transition portions of the rectangular metal shell obtained after the first drawing molding, so that a plurality of second convex strips are formed in a second area between the two arc corner transition portions of the side face plate.
