TL;DR: In this paper, a pipe material connecting tool is proposed to connect and fix corrugated pipe material to a through hole while maintaining high waterproofness, using a rotary lock body and an engagement piece.
Abstract: PROBLEM TO BE SOLVED: To provide a pipe material connecting tool capable of easily connecting and fixing a plurality of types of independent ring type corrugated pipe material to a through hole while maintaining high waterproofnessSOLUTION: A pipe material connecting tool 1 connects and fixes an independent ring type corrugated pipe material 3 to a through hole 61 formed in a wall 60 The pipe material connecting tool 1 includes a socket 10, a rotary lock body 30, and a bell mouth 40 The socket 10 is attached to the outer periphery of the corrugated pipe material 3, such that the movement in the direction of the axis O is restricted by the engagement of an engagement piece 19 When an insertion portion 42 of the bell mouth 40 is inserted into the pipe of the corrugated pipe material 3 from the distal end side, detachment of the bell mouth 40 from the corrugated pipe material 3 is regulated by the engagement of an engagement claw 44 When the rotary lock body 30 is screwed onto the outer periphery of the socket 10, the wall 60 around the through hole 61 is pinched by the rotary lock body 30 and a flange portion 46 of the bell mouth 40 As a result, the corrugated pipe material 3 is connected and fixed to the through hole 61SELECTED DRAWING: Figure 8

TL;DR: In this paper, a blower and a motor mounted on a central shaft of an impeller were described. But the motor was not mounted on the impeller itself, but on the rear surface of the blower, where one end of the motor is disposed in the impellers, and the other end was exposed to the outside.
Abstract: The present invention relates to a blower and a blower system having the same. The blower according to one embodiment comprises: a bell mouth configured to suck ambient air through the front; an impeller inserted into the rear surface of the bell mouth to discharge the outside air sucked in the bell mouth to the outside; and a motor mounted on a central shaft of the impeller to transmit rotational force to the impeller. The motor is inserted into the rear surface of the impeller, one end of the motor is disposed in the impeller, and the other end of the motor is exposed to the outside from the rear surface of the impeller.

TL;DR: In this paper, a method for determining a gathering bell mouth position on a detaching roller output web of a combing machine is proposed, which is based on a segmental weighing method.
Abstract: The invention discloses a method for determining a gathering bell mouth position on a detaching roller output web of a combing machine The method comprises the following steps of: calculating a weight distribution curve in the length direction of a detaching cluster by using a segmental weighing method; (2) calculating the weight distribution curve of the detaching roller output web; (3) calculating a distance between each segment of web and a bell mouth; (4) calculating the total weight yc of the web at a point C; (5) calculating the weight CV (%) value of an output combed sliver; (6) setting values a and b according to the effective output length of a detaching roller of the combing machine, calculating the weight of an output sliver, and determining the position of the bell mouth, ie, the values a and b by taking a minimum weight CV (%) value of the sliver as an optimization target The position of the bell mouth, ie, the values a and b is determined by taking the minimum weight CV (%) value of the bell mouth output combed sliver as the optimization target, so that the uniformity and quality of the output combed sliver of the combing machine are ensured

TL;DR: In this paper, a forming die for a large-diameter fused bell and a spigot type structured wall pipe was proposed, which enables problems in manufacturing of bell mouths of large diameter steel band-reinforced spiral double-wall bellows and hollow wall coiled pipes.
Abstract: The invention relates to a forming die for a bell mouth of a large-diameter fused bell and spigot type structured wall pipe. The forming die enables problems in manufacturing of bell mouths of large-diameter steel band-reinforced spiral double-wall bellows and hollow wall coiled pipes to be overcome and fills in domestic and international gaps.
