We designed and made a circular loom of Fayolle-Ancet type with electro-magnetically operated shuttles, replacing rectilinear motion of plain looms by circular and continuous motion with several shuttles running simultaneously. The warp yarns, with equal tension from two beams located at both sides of the loom, pass upward through circularly disposed distributing reeds, enter two harnesses running horizontally in radial directions and then pass through a horizontal stationary reed on which there are four shuttles...

We designed and made a circular loom of Fayolle-Ancet type with electro-magnetically operated shuttles, replacing rectilinear motion of plain looms by circular and continuous motion with several shuttles running simultaneously. The warp yarns, with equal tension from two beams located at both sides of the loom, pass upward through circularly disposed distributing reeds, enter two harnesses running horizontally in radial directions and then pass through a horizontal stationary reed on which there are four shuttles running simultaneously. The harnesses are controlled by central cams. Through their inward and outward radial motions, the harnesses alternately open and close the shed of the warp yarns to let the shuttle pass through. Each shuttle is held in position by a piece of electromagnet, which drives it through the warp yarns. The usual beating up motion of the reciprocating slay is also replaced by the continuous circular motion of a specially designed spiked-wheel, disposed at an inclined angle to the yarn, for laying and tightening the pick (weft). The circular or tubular shaped fabric thus formed is then flatened and received on a roller placed on the upper part of the loom. The chief defect we found is that the shuttles very often run out of way. We are trying to make further improvements.

圆型織機以圓運動代替了普通平型織機的往復運動,是一個革命性的改進。我所設計的圓型織機已由本院金工埸試製成功,兹介紹其基本構造原理如下: 經紗盤頭用兩倜,分列左右,合用一個調整螺絲來調整兩面的張力,維持其相等。經紗自盤頭引出,向上穿過圆形分布筘,就排列成圆筒形,然後通過開口綜絲而穿上靜止筘;筘上有圓梭四只。綜絲開口,由凸输控制;凸输迴轉時,綜絲卽引導經紗交替開閉,讓四只梭子带着緯紗依次相接通過其開口而前進。梭子是藉電磁鐵吸住在兩對羅拉上而推送前進的,並不吸住在電磁鐵面上,以避免拖住經紗。打緯運動,用一倾斜有刺輸跟随於梭後,将閉口後織口内的緯紗壓緊,也以圆運動代替了—般往復的打緯運動,可以减少一般打緯筘對於經紗的来回擦傷。又因開口比一般平型織機爲小,所以經紗張力的變化也小,可以减低經紗的断頭率。織成的圆筒形布,撑平後向上捲取。目前階段主要缺點爲梭子易脫出,當待繼續改進。

Three most important mechanical properties of the piston ring. and its vital relations to the reciprocating engine are discussed in this work.

本文是第一机械工業部提出的题目“活塞环研究”的一部分。主要目的是測取环脹力的分布规律,並在理論上与試驗上尋找弹力降低与温度时間之間的关系。内容有以下三方面。(1)采用新方法测取脹力。过去方法(如文献①→⑦))都有缺点,且所用設备复雜而不經济。本文就我们已有的設备用精确度较高的电阻应变儀及光彈性方法進行测量。並测取环在汽缸中的真实应力,以資校核。(2)計算脹力与变形的关系,特別是高点环理論形状的計算。(3)計算並試驗弹力降低(松弛)与时間及溫度的关系。

Helical springs are widely used in dynamic systems and are frequently subjected to vibrational fatigue failure. The dynamic effects due to vibration should be taken into account by the designer if fatigue failure is to be avoided. In the present paper the dynamic characteristics of helical springs subjected to a reciprocating motion is investigated theoretically ard experimentally. The mathematical model of longitudinal vibration bars is directly used for the dynamic analysis of helical springs. Force trans mittanos and dynamic spring modulus formulae are given. It is convenient for designer to estimate the range of frequency the spring is allowed to operate.

螺旋弹簧多用于动力系统且常易发生疲劳破坏。为了避免弹簧的疲劳破坏,设计者应对弹簧由振动所引起的动力影响加以考虑。 本文对承受反复运动的螺旋弹簧的动态特性进行了分析与试验。直接把均匀杆纵向振动的数学模型用于弹簧的动力分析。给出了力的传递比和动弹簧模量公式,便于设计者估算弹簧所允许的工作频率范围。
