This paper reports a new microforce generating machine under development at NMIJ, AIST. We proposed a new microforce generating method by referring to the principle of the Kibble balance experiment and planned to apply it to a rotary type machine. Microforce in the micronewton and millinewton range can precisely be generated using this newly developed machine.

Ergonomic Intervention

A pedal-operated cleaner-cum-grader having common bicycle chain-sprocket mechanism to get the speeds of 240 and 720 rpm of eccentric shaft and blower shaft, respectively for the desired cleaning/grading of grains was developed earlier by CIAE, Bhopal. Also, in order to utilize the human energy in more efficient way through pedalling mode, CIAE has recently developed a dynapod. The dynapod is a pedal operated rotary device, which can be used as an interface between human worker and any rotary-type machine. The developed dynapod was used to operate the cleaner-cum-grader to assess the drudgery reduction in its operation in comparison to original pedalling mechanism. The dynapod was interfaced with the cleaner-cum-grader by carrying out minor modifications in the original unit. Eight male agricultural workers with mean stature and weight as 168.4 cm and 54.4 kg, respectively participated in the study. The cleaner-cum-grader was used for cleaning and grading of soybean grains. Heart rate of the workers was measured during operation of cleaner-cum-grader using the dynapod as well as the original pedalling mechanism. Mean working heart rate during operation of machine with original pedalling mechanism was 114 beats min-1 as against 108 beats min-1 in case of pedalling with dynapod. The work pulse (ÄHR) with the original pedalling mechanism was 35 beats min-1 as against 29 beats min-1 during pedalling with dynapod. The output capacity of the machine increased from 303 kg h-1 in case of original pedalling mechanism to 345 kg h-1 with dynapod. Considering the cardiac cost as well as output of the machine, the drudgery reduction by using dynapod with cleaner-cum-grader was about 25.4% as compared to the original pedalling mechanism.

Agricultural organic waste chopping machine are tools that can be used to chop leaves, twigs and could be used to help farmers in processing of the agricultural disposal products such as stalks and corn stalks, cassava stems, rice stalks in order to accelerate farmers in processing of those disposal in order that the plantation land can be prepared immediately for subsequent cultivation, as well as the chopped products can be reused for various purposes such as animal feeds and composts fertilizer. The research of this engineering method is carried out with the following stages: (1) study of the characteristics of several organic wastes to be enumerated, (2) analysis of the Chopping machine elements, consists of Chopping Blades, the house of the chopper blades, hopper, frame and transmission system. (3) A Prototype chop up mechanism manufacturing. And (4) Functional testing machine. The Copping Machine design resume as follows: Production capacity of enumeration 220 kg / hour. The cutting mechanism uses 2 static blades and 6 rotary blades. Transmission system using Belt-Pulley mechanism. The 24 Hp Diesel engine is used.

Abstract Project 70 stainless type 303 and Project 7000 stainless type 303 are free-machining stainless steels of the austenitic chromium-nickel type. They offer significantly improved machinability and longer tool life. These steels are suited particularly for automatic bar-machine and Swiss-type machine operations where longer tool life results in more productive machining time. Applications include shafts, valve bodies, valves, valve trim, and fittings. This datasheet provides information on composition, physical properties, hardness, and tensile properties as well as fracture toughness and creep. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: SS-409. Producer or source: Carpenter.

Maguin (France) is still active in the application of pulsed electric field (PEF) technology. After having carried out successful tests on a 10 t/h pilot screw-type machine on sugar beet cossettes, a new application system based on a roller technology has been developed. This technology allows a wide range of application due to its flexibility with flowrates and materials. A variety of process schemes are proposed to ensure the best performance of the PEF technology.
