The present disclosure relates to an additive manufacturing (AM) method for making a three-dimensional (3D) object, comprising a) depositing successive layers of a powdered material (M), at least partially recycled, comprising at least one poly(ether ketone ketone) (PEKK), having a phosphorus content of more than 30 ppm, as measured by Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES), and b) selectively sintering each layer prior to deposition of the subsequent layer.

Additive manufacturing method for making a three-dimensional object using selective laser sintering

The present invention consists of a new distribution device for use with conventional seeding meters. The system consists of a seed meter for dispensing a predetermined amount of seed and the distributor of this invention disposed below the dispenser. The invention is of a plate having an intricate geometrical configuration positioned below the volume or weight seed distributor to insure that the seeds are contained for controlled fall toward the ground and a portion shaped to provide even distribution of the seed whether or not the seeds are distributed by the center or either side of the present seed distribution system.

Seed distribution device

An agricultural machine operative to pick up, convey and invert a swatch or windrow of hay for the purpose of accelerating the curing thereof. The machine has a mobile frame which carries at its fore part a swath-straddling pick-up which function to pick up the swath bodily and to convey it rearwardly and then obliquely to the line of advance for return to the ground or stubble as an inverted swath ribbon or mat. The oblique conveyor comprises a plurality of parallel, closely side-by-side belts whose upper runs carry the swath ribbon from the pick-up mechanism to a discharge zone at which the discharge ends of the belts are arranged in staggered fashion along a line oblique to the path of travel of the belts.
