PENGARUH PEMBERIAN VARIAN HERBAL JAHE (Zingiber officinale) DENGAN AUTOMATIC FEEDER TERHADAP PANJANG TUNGKAI (FEMUR, TIBIA, METATARSO) PADA ITIK (Anas javanicus)

This study aims to determine the effect of giving ginger elephant and ginger empiric herbs by using automatic feeder or manual feed tool to the length of the leg bones (femur, tibia, metatarso) in ducks. This study used randomized randomized controlled trials with four treatments and three repetitions. GP1 (Feed + Automatic Feeder + Elephant Ginger 2%), GP2 (Feed + Manual + Elephant Ginger 2%), EP1 (Feed + Automatic Feeder + Emprit Ginger 2%), EP 2 (Feed + Manual + Empritic Ginger 2%). The parameters measured were the length of the leg bones (femur, tibia, metatarso) of ducks. The results of the analysis showed that the total bone length of the femur was 6.51 cm with Fcount (0.038) <Ftable (5.32), the total length of the total tibia bone was 11.9 cm with Fcount (1,313) <Ftable (5, 32), and the results of the total length of the metatarso bone are 6.67 cm with Fcount (0.668)> Ftable (5.32). These results indicate that the effect of giving ginger elephant and empirical ginger using a feed device Automatic feeder or manually has no significant effect (P> 0.05) on the length of the leg bones (femur, tibia, metatarso) of ducks. The results are not significantly different which causes the Automatic feeder tool to be a new breakthrough for replacing the manual feed tool for feeding ducks

Feasibility Analysis of Switching on Rectifier Function of Regenerative Energy Feed Device

At present, the diode rectifier unit which is widely used in traction power supply of urban rail transit has the disadvantages of large DC output voltage fluctuation range and only one-way energy flow. By analyzing the output characteristics of the existing 12 pulse-wave rectifier units and the typical output characteristics of the medium-voltage energy-feed device, it is concluded that the energy-feed device is based on the high-power PWM rectifier and its power transmission and DC output characteristics are completely controllable, so it can be operated in parallel with 12 pulse-wave rectifier units.

Principle Analysis of Profiled Bar Turning Peeling Machine

Through the study of regular polygon cross section continuous forming processing technology of rotary cutting machine, this article designed a profiled bar turning peeling machine. This machine is mainly composed of workpiece axis, cutter axis, feed device and pulling device, etc . Parallel mounted, workpiece axis and cutter axis rotate at a rotational speed ratio in the same direction so as to form complex turning motions, during which the cutting track of the knifepoint relative to workpiece axis forms a shape of approximate linear closed curve, at the same time, feed device and pulling device pull workpiece moving along the axis, through which this machine can complete a turning finish of a whole workpiece at a time. This article analyzed the turning peeling principle of profiled bar, established a motion trajectory equation for the knifepoint relative to the workpiece axis, analyzed the processing straightness error of turned profiled bar, and then derived the error calculation formula.

Control of Magnetic Suspension Linear Feed System

A magnetic suspension linear feed device has been introduced in this paper, it is consist of linear motion and suspension parts. The mathematical model of suspension system is modeled. Aiming at the suspension part which is an nonlinear and strong coupling system, the auto-disturbance rejection controller (ADRC) is used. The inner disturbance and outside disturbance is observed and compensated, the result of simulation indicates the suspension control A magnetic suspension linear feed device has been introduced in this paper, it is consist of linear motion and suspension parts. The mathematical model of suspension system is modeled. Aiming at the suspension part which is an nonlinear and strong coupling system, the auto-disturbance rejection controller (ADRC) is used. The inner disturbance and outside disturbance is observed and compensated, the result of simulation indicates the suspension control has better dynamic, static and robust characters by using the auto-disturbance rejection controller.

Flapper Feed Device for Improved Productivity of Cassava Grater

A modified hopper design of the conventional cassava grater and its concomitant productivity improvement is presented. One of the sides of the inverted truncated rectangular pyramidal hopper was hinged at the lower end and swung through angle of 15 to 30 degrees. This flapper swing served as feed for the rotary grater. The flapper allowed the cassava tubers to be fed over a larger grater surface area permitting cassava feed over an angle of 120 degrees instead of the usual 90 degrees. It further allowed the variation of the space between the rotary grater and the hopper thereby enhancing complete maceration of the tubers. The presence of ungrated cassava chips in the macerated mash common feature with conventional graters was reduced to negligible proportions. A process improvement of up to 100 per cent in thru-put was obtained compared with the conventional graters.
