Abstract: A system for transferring a particulate material from a first container to a second container including an upper portion, a lower portion and a sieve. The upper portion having a housing and a high frequency vibrator, the housing having a first end, a second end opposite the first end, and a gasket positioned adjacent the first end. The lower portion having a collector funnel, a low frequency vibrator and a collar securing the low frequency vibrator to the collector funnel. The sieve having a mesh size, a perimeter and a gasket positioned adjacent the perimeter. The upper portion is releasably secured to the first container and the sieve is releasably secured between the second end of the upper portion and the lower portion.

Abstract: A grill apparatus for use with an open fire and tripod suspension. The grill apparatus having a wall, two grill members and a rotation bracket. The wall is used to protect the food from falling off the grill. The grills rotate inside and between the bracket ends. The second grill member used to expose the second side of the food to the fire.

Abstract: A single-shaft track-changeable vibration exciter comprises a vibration box (1), a bottom seat (2), a vibrating spring (19), and a vibrating shaft (3). The vibrating shaft (3) is set on the vibration box (1). The vibrating spring (19) is set between the vibration box (1) and the bottom seat (2). Multiple groups of track-restricting rod assemblies that are arranged aslant are set in two sides of the vibration box (1), and each group of the track-restricting rod assembly comprises two track-restricting rod assemblies that are arranged symmetrically in the both sides of the vibration box (1). Both ends of the each track-restricting rod assembly are hinged respectively on the vibration box (1) and the bottom seat (2).

Abstract: A dryer for material to be dried (T), wherein an air supply channel (4) for supplying a drying gas to the drying region is provided, and at least one exhaust-gas opening (8) is provided for removing the drying gas, wherein the air supply channel (4) is surrounded at a distance by an outer wall (11), which has at least one supply opening (12) and at least one removal opening (13) for the cooling medium (K), wherein between the at least one supply opening (12) and the at least one removal opening (13) a flow section (14) for the cooling medium (K) is formed between the outer wall (11) and the air supply channel (4).

Abstract: A sifting device including a sieve box (1), which is caused to oscillate using a drive (4), as a fundamental oscillation system having essentially horizontal first transverse carriers (1.3) and a supplementary oscillation system (2), attached to the sieve box (1), having essentially horizontal second transverse carriers (2.3), positioned essentially parallel to the first transverse carriers, which are each positioned between two first transverse carriers (1.3) and are connected thereto by stretchable sieve liner strips (3), with, for two sequential transverse carriers, the transverse carrier closer to the feeding side (A) being higher than the subsequent transverse carrier, which is closer to the discharge side (B), with the sifting device having at least two sections, in which the height difference between the centers of gravity of two sequential transverse carriers (1.3, 2.3) is greater in the particular feeding-side section than in the discharge-side section.

Abstract: An oscillator apparatus for sorting out pieces of lumber for separating smaller scraps of wood from larger usable pieces of wood. The oscillator apparatus for sorting out pieces of lumber includes a base assembly including leg members and elongate side members interconnecting pairs of leg members; and also includes a table assembly being movably mounted upon the base assembly; and further includes an oscillator assembly being mounted to the base assembly for oscillating the table assembly.
