Abstract: An improvement to prior art bag closure affixing devices of the type embodied in U.S. Pat. No. 3,163,967 to easily accommodate bags of various neck widths without the need for gear or sprocket changes. The improvement encompasses a modified clutch control for the bag closing head. The clutch is controlled by a clutch actuating arm which is mechanically connected to the clutch. When the actuating arm is depressed, the clutch disengages from a first stop surface and rotates only partially until engaging a second stop surface. The second stop surface remains in contact with the clutch, preventing completion of the closing cycle, until the bag neck completely passes over the actuating arm and the actuating arm is released. The second stop surface then disengages the clutch allowing the bag closing head to complete a closing cycle with bags of varying neck sizes without frictional damage to the bag or incomplete entry of the full bag neck.

Abstract: The present invention describes a self-propelled or pulled baler for producing bales of agriculturally-harvested crops. Harvested crops are compressed in the feeding channel before entering the actual baling chamber. For this purpose a sensor reaches into the feeding channel. Crops will be pushed against the sensor by the feed rakes. As soon as a pre-adjusted pressure can be measured at the sensor, and the baling ram has moved towards the front dead center position, the motion track of the feed rakes will be switched so the compressed crops located in the feeding channel will be fed into the baling chamber through a single loading stroke. The change of the motion track of the feed rakes dependent upon the pressure sensor has the advantage that, with each loading stroke, an equal amount of compressed crops are fed into the actual baling chamber. Thus, bales of a consistent density can be produced.

In addition, the rope core (2) is surrounded by a rope sheathing (4) provided with a protective layer (5) impervious to particles of dirt.

Abstract: In a combustion chamber, the hot gases are prepared sequentially via two stages (20, 40). Arranged at the end of the first stage (20) in the direction of flow is a cross-sectional constriction (30) via which the hot gases (21) prepared in the first stage (20) are passed over into the second stage (40). The Mach number at the outlet (31) of this cross-sectional constriction (30) corresponds to the area ratio of outlet area (A2) over inlet area (A1). This results in a low-reflection configuration in which low-frequency vibrations are absorbed to a significant extent. And acoustic energy reflected from the turbine is substantially reduced.
