A new belt transmission mechanism, having the function of no-slip driving, is described in the paper. It is composed of pulleys with carved rails and belt with rolled pins spaced out on both sides. Firstly, the trajectory curve is deduced along which pins embedded in the pulley. And then, parametric relationships are established, which are about center offsets of two pulleys, working radius of ...

Although the effectiveness of automobile safety belts in reducing risk of serious injury in traffic crashes is well documented, safety belt use in many U.S. jurisdictions remains low. Michigan's mandatory safety belt law for front-seat occupants, implemented in July 1985, is one of 34 similar laws in the United States intended to increase belt use and reduce crash-related injuries. Using time-s...

Spinal loading during weightlifting results in a loss of stature which has been attributed to a decrease in height of the intervertebral discs--so-called 'spinal shrinkage'. Belts are often used during the lifting of heavy weights, purportedly to support, stabilize and thereby attenuate the load on the spine. The purpose of this study was to examine the effects of a standard weightlifting belt ...

We present the results of radio searches for pulsars within unidentified EGRET source error boxes. Using the Parkes multibeam system, we have surveyed 56 sources at Galactic latitudes |b| > 5◦ which do not appear to be associated with blazars. This population has been suggested to be distributed like the local star forming region known as the Gould Belt, the Galactic Halo, and/or the millisecon...

in this project, first we introduced a general rule for the design of drying processes and then, we have applied microsoft excel for this purpose. belt dryer is one of the most common dryers in the food industry. in this study, our aim was to process carrot by this dryer. we optimized the target function (total annual cost or tac) and investigated the influence of design variables on this targe...

Overview: The size distribution of the main belt is governed by collisional evolution as well as by the non-collisional removal of bodies due to the combination of radiation forces and resonances. The NEA size distribution is governed in part by the size distribution of the main belt, it’s primary source, but differs somewhat from the main belt due to the size dependent processes which deliver ...

[Purpose] The aim of this study was to compare toe grip strength and muscle activity during toe grip strength exertion according to the presence/absence of an ankle immobilization belt and to examine the relationship between the differences in muscle activity and toe grip strength. [Subjects] The Subjects were 13 healthy young women. [Methods] We measured toe grip strength and muscle activity d...

The ability of manipulating exible objects, such as rubber belts and paper sheets, is important in automated manufacturing systems. This paper describes a novel approach to assembly of exible objects. The operation dealt with in this paper is to assemble a rubber belt with xed pulleys. By analyzing possible states of the belt based on the empirical knowledge of the belt, we can derive a method ...

In the present study, the 3-dimensional artistic relief designs on the leather belt used to create CNC tool path and the parameters were investigated in the production of hot pressing molds. The 3-dimensional relief patterns obtained with the help of belt pressure molds consist of marks pressed along the belt with the hot press. These intricate patterns create the varieties in the world of wear...

We have compiled data on textures, trace element contents, Hf isotope compositions and U-Pb ages of zircons from lower crustal xenoliths the central part Columbia supercontinent in Precambrian areas North America, Siberia Northern Europe to address question when host rocks became continental crust. The time crust reached its current state, a layer high-pressure granulite-facies rocks, is dated ...
