Abstract: A large magnetic separator for separating magnetic fines from nonmagnetic product is equipped with a dual mode power supply. A first mode of the dual power supply is provided for accelerated imposition of the design magnetic field. A second mode of the dual power supply is provided for the maintenance of the desired magnetic field at an improved power factor, which field is in the range of 20 kilogauss. With the field imposed, a canister centrally placed in the magnet with a magnetic stainless steel wool matrix separates magnetic fines from nonmagnetic product until the matrix is saturated. Upon saturation of the matrix, the power supply dissipates to the power grid electrical energy from the collapse of the magnetic field. There results a larger classifying duty cycle of the high stationary magnetic fluid utilized for classification.

Abstract: A liquid or powder measurement apparatus, usable also for mixing a plurality of measured materials and for distributing the mixture to a plurality of dispensing containers. A flow control valve having a wide flow rate range and excellent linearity between the degree of valve opening and flow rate is disposed in each of the liquid flow paths and is adjustable to have a flow rate linearly varying with the stroke of the valve. A mixing container receives the raw material from one or more supply containers and is weighed by a load cell to thereby detect the amount of material flowing into or out of the mixing container. A control unit operating according to fuzzy logic compares the measured weight with a target weight and accordingly adjusts the flow rate of a selected one of the flow regulators. The same load cell and control unit can also control the flows from the mixing containers to the dispensing containers.

A pair of end ball rollers are attached to a second driving shaft and located in correspondence to the end feed rollers. A double-structure bail roller is attached to the second driving shaft in correspondance to the feed rollers, except for the end feed rollers. The double-structure bail roller includes an inner core and an outer layer having a small friction coefficient. The iner core is elastically deformable in a direction in which the end feed rollers are pressed against the corresponding bail rollers.

Abstract: Bulk material that is difficult to feed, such as glass fibers, is fed from a storage bin into a feeding chute driven by a vibratory drive which vibrates the chute in a longitudinal direction of the chute, that is, in the feed advance direction of the chute. The chute may be a so-called loss-in-weight feeding chute. In order to assure a uniform, constant material flow without any bunching and without any gaps in the flow for an accurate feeding, the material flow is exposed or influenced by a further vibration effective in a direction substantially across the feed advance direction. For the purpose a vibrator with vibrating elements extending in the feed advance direction vibrates in the cross-direction. These vibrating elements are so located that they can make the material flow through the chute more uniform.
