Abstract: A device for baling crop comprising a baling chamber having an inlet port and a ram adapted to reciprocate along said port and an auxiliary space joining the inlet port outside the baling chamber for temporalily storing crop to be compressed, said device is provided with a blocking member for predensifying the crop as well as compressing means for compressing the crop in a transverse direction in said auxiliary space, the blocking member is driven by means of a cam/cam wheel mechanism actuated by said ram, while said device furthermore comprises retaining members in said baling chamber to prevent rebounding of crop material already compressed and/or to retain crop in said baling chamber if said chamber is opened during the discharge of a bale.

Abstract: An agricultural implement for raking or spreading crop lying on the field, for example, mown grass, comprising at least one carrier rotatably driven around an upright axis and having upright shaft pins arranged in a circle, on each of which is journalled in a freely pivotable manner a crop-engaging, tine-shaped element of non-circular cross section, wherein a flexible member independently of each element is arranged so that the tine-shaped element is held in an outwardly directed position with respect to the upright axis, said tine-shaped elements preferably consisting of two or more tines in overlying position the bending resistance in the vertical plane of the superjacent tines differs from that of the lower-tine.

Abstract: A device for treating solid and/or liquid materials comprises a drum driven for rotation about a horizontal axis by means of an endless chain.An expensive toothed rim surrounding the drum is avoided, as it is possible that the chain engages a toothless portion of the drum periphery.

Abstract: A device for baling cut crop, comprising a baling chamber having an inlet port and an outlet port and a compression member adapted to move in the baling chamber, the compressing stroke of the compression member extends along the inlet port to near the outlet port and is equal to or slightly larger than the distance between the inlet and outlet ports; a construction of the device according to the invention is suitable for making bundles having a materially higher "specific weight" than the generally known "straw bales".

Abstract: A mobile baler includes a horizontal baling chamber having a lateral collection chamber discharging thereinto. A ram moves back and forth across the discharge mount of the collection chamber and a closure member, controlling transfer of material from the collection chamber to the baling chamber, moves in concert with the ram. The baling chamber is normally closed at one end by a movable end wall and the drive means for the ram connects this end wall with the ram so that the end wall is held in closed position as the ram compresses material between it and the end wall.

Abstract: A compressive chamber of a baling device is open at both ends. Associated with one end is a movable closure member and a ram projects into the chamber from the opposite end. Drive mechanism directly connects the ram and the closure member so that in one direction of drive the closure member is forced into and held in closed position while the ram travels toward it and, in the opposite direction of drive, the ram and closure member are forced apart to unseat the closure member and move it to open position.

Abstract: A device for compressing crop, for example grass, hay or the like, into bales comprising a baling chamber and a ram adapted to reciprocate therein, provided with at least one retaining member operating in the compression chamber and removable therefrom, in order to prevent that after compression the crop rebounds so that part of the empty space between the crop already compressed and the retreating ram is re-occupied by the rebounding crop, the freshly introduced quantity of crop being thus reduced.

Abstract: A device for compressing crop into bales comprising a compression chamber having an inlet opening and a pressing member adapted to reciprocate along said opening and feeder mechanism for introducing the crop through the inlet opening into the compression chamber, which device is intended for making bales having a high specific weight; the device is able to be operated continuously.

Abstract: A device for cooling castings and for treating moulding sand comprises a driven, rotatably journalled drum provided with internal catches extending substantially axially between an inlet end and an outlet end of the drum.For improving the stirring effect of the catches and for avoiding damage of castings and loss of valuable dust from the moulding sand, the catches have a stronger scooping effect near the inlet end than near the outlet end.

Abstract: A device for baling crop, for example, grass, hay or the like, comprising a compression chamber and a driven plunger reciprocating in said chamber as well as a binding means adapted to bind a bale still located in the compression chamber; the compression chamber and the plunger are each provided with at least one channel opening towards the compression space so that in the extreme pressing position of the plunger the channel of the compression chamber and that of the plunger constitute an uninterrupted, annular conduit for passing a length of binder, whilst a mechanism is provided for interconnecting the two ends of the length of binder.

Abstract: Apparatus is disclosed which functions to adjust the moisture content of casting sand as it is being recovered, so that the sand may be re-used without significant or further adjustment of its water content. The apparatus includes a cooler-drier which receives hot castings and sand and discharges the sand and castings separately. A water spray impinges upon the sand and castings as they are moved through the cooler-drier and a temperature sensor which senses the temperature of the sand/castings mixture at the inlet controls the water spray so that the discharged sand possesses a uniform and selected moisture content.

Abstract: An apparatus for cooling castings and cooling and drying moulding sand, comprising a horizontal drum rotatable about its longitudinal axis and having an inlet opening for castings and casting moulds at one end and an outlet opening for castings at the other end. The drum wall first has an impermeable part which is followed by a perforate part for the discharge of moulding sand. An underlying descriptive line of the drum viewed in the direction from the inlet end to the outlet end slopes upwardly at least for a part and this gives rise to several embodiments.
