Title: Soil working machine for tractors - has tools arranged in groups transverse to direction of travel
IPC: A01B33/06
Filed: 1975-01-16
Abstract: The soil working machine can be conn acted to a tractor with several working tools, such as rotary harrows, which turn about axes. Some of the tools are releasably fixed and arranged such that they can be exchanged with respect to tools of other operating width. The tools are arranged in groups transverse to the direction of travel and these of each group are supported in a frame section, which is releasably connected to the machine at two points so that it can move upwards and downwards. Each tool can be adjusted in working height independently of the other groups. Hence the prongs can maintain their set engagement depth over the whole width of the machine. Good adaptability to the soil is thus achieved despite the long working width of 5 m.

Patent FR-2334565-A1 (FR)
IPC: B65B35/44
Filed: 1976-11-18
Abstract: The containers, such as, for example, bottles or glasses, are conveyed forwards in a plurality of longitudinal rows lying next to one another and, starting from the end face located at the front in the longitudinal conveying direction, are successively allocated to packaging units having a plurality of transverse bottle rows. The formation of the packaging units takes place in that, at a specific point along the conveying stage, an acceleration in the longitudinal conveying direction is imparted to the particular container (2) of each longitudinal row (12) located at the front, as seen in the conveying direction, so that an always equal spacing is obtained between the individual containers (2) in the longitudinal conveying direction. After the specific conveying stage, the conveying speed of only the first container (2) of each longitudinal row (12) is reduced. After a desired number of transverse container rows (13) have run up against the containers (2) of reduced speed, the conveying speed of the transverse container row (13) then following is reduced, before it runs up against the leading transverse row (13). The packaging units thus formed are pushed into the folding box transversely to the longitudinal conveying direction. The apparatus has spacer bosses (3) rotating essentially continuously between the longitudinal conveyors (1) and separating slides (7) arranged at a distance behind the spacer bosses, the conveying speed of the spacer bosses (3) and of the spacing slides (7) being lower than that of the longitudinal conveyors (1).
