Abstract: A sieve for a grain combine has a plurality of longitudinal sections. Each section is pivotally mounted in a sieve frame. A sensing means senses if the combine is leaning to one side. The sensing means controls a drive and linkage mechanism for pivoting each of the sections relative to the sieve frame to maintain each section generally horizontal. Elastomeric seals extend between each of the sections.

Abstract: The invention relates to the electric heating of animal scent using a wick to draw scent from a container and a resistive heating element.

Abstract: A combine for cutting and threshing grain has an axial flow threshing drum. A feeder head mounts to the forward end of the threshing drum. Impellers on the feeder head push grain into the threshing drum housing and also provide threshing. Rasp bars on the feeder head thresh the crop prior to reaching the threshing drum while pushing the crop through perforations in the feeder housing. The feeder housing and threshing drum housing rotate, but at a slower speed than the threshing drum. A brake will prevent the threshing drum housing from rotating at an excessive speed. Clearances between the threshing drum and threshing drum housing, and clearances between the feeder head rasp bars and feeder housing, ca be adjusted for different crop conditions.

Abstract: A header for a combine moves between retracted and extended positions. The header has a platform with at least two platform sections. The platforms will extend in longitudinal directions relative to each other. A rotatably driven auger is mounted to the platform and has at least two auger sections. The auger sections telescope. The helical flight on one of the sections collapses when the auger sections retract. A sickle has at least two sickle sections. A sickle extender moves the sickle sections in longitudinal directions relative to each other. A drive mechanism reciprocates the sickle sections relative to the platform for cutting vegetation.

Abstract: The present invention is a step assembly for insertion into swimming pools. A frame having a plurality of steps connected in an end-to-end fashion rests on the bottom of the pool and adjacent to a pool sidewall. An adjustable adapter step is connected near the top of the frame and overlaps a top rail of the pool sidewall. A ballast box is located near the bottom of the frame beneath a lower step to prevent the frame from floating in the water. A pair of hand rails are provided which extend above the steps on both sides of the frame to allow ease of entry and exit into the water. A cushioned strip is provided along the bottom and sides of the frame to guard against tears in a pool liner.

Abstract: A combine for harvesting and threshing grain has features to prevent grain and time wastage even if the combine is tilted sideways, and other features to simplify the threshing equipment. The combine has a sieve housing that is mounted on rollers to the frame. These rollers allow the sieve housing to swing like a pendulum if the combine tilts sideways. The combine has inner and outer cylindrical bodies that rotate together opposite to the rotation of a threshing drum. The threshing drum and grate are conical with the rearward end being smaller than the forward end. A beater for beating grain rotates with the threshing drum, causing grain to fall through slots located in the inner body. The space between the inner and outer body contains a helical flight for transporting this rescued grain back to the forward end and to the sieves. Elevating rings mounted to the outer body rotate with the outer body to lift material from the sieve to the bin, if clean grain, and back to the threshing grate, if tailings.
