Inventor: RATZLAFF HOWARD J
IPC: A01D90/08
Filed: 1988-09-23
Abstract: The baler has a "vertical" bale starting chamber in which the upwardly moving rear belts (332) and the downwardly moving front belts (330) cooperate to tumble and roll incoming material into a bale (B). When the bale reaches full size in the expanded chamber, the bale is lifted while still in its chamber to a wrapping station where it continues to spin as a binding wrapper is applied. During the lifting of the finished bale (81) and subsequent application of the wrapper, fresh material entering the continuously moving baler is confined beneath the finished bale in a new starting chamber, whereupon the cycle is repeated. As the new bale (B2) grows, a discharge ramp becomes formed by certain stretches of the belts and rollers to gravitationally discharge the wrapped bale from the baler without stopping advancement of the machine. An accumulating trailer (386) is hitched to the baler in a position to receive bales from the discharge ramp as they gravitate down the same and to temporarily store the accumulated group of bales until the operator selects a site for dumping the bales.

Abstract: The thin-film magnetic head is to be guided over a recording medium which is to be vertically magnetised and into which flux transitions of predetermined recording wavelength and density of flux transitions are to be recorded along a track. It includes a conducting element similar to a ring head, which conducts the magnetic flux and has two magnet legs which form magnet poles arranged one behind the other and separated by a gap of predetermined width and have predetermined expansions in the direction of movement. With this magnetic head, it is intended for the complexity of signal processing in a read-write channel to be reduced. According to the invention, for this purpose the magnetic head satisfies the following relationship, at least approximately:…  lambda <*> = g + Max(A1, A2), where  lambda <*> is the recording wavelength which is obtained for the value Dp of the density of flux transitions (D) at which the read voltage (V) of the magnetic head (2) is at a maximum, g is the width of the gap (12) and Max(A1, A2) is the greater value of the two expansions (A1, A2) of the magnetic poles (P1, P2). …<IMAGE>…
