Title: Harvesting device for harvesting maize
Inventor: SANDERS LAMBERT
IPC: A01D45/02
Filed: 1988-03-12
Abstract: Our present invention relates to a harvesting device for harvesting maize which is designed as an attachment for combine harvesters. This harvesting device is provided with a draw-in device and a picking gap for separating the cobs from the plant, the harvesting device having only one picking roller per plant row, which is assigned a part casing provided with cutter passage slots. The picking roller has in this case striking plates arranged at a uniform spacing from one another, the striking plates having incisions, through which the cutters extend. The cutters themselves are fastened on a crosspiece running transversely to the harvesting machine. For the purpose of easier exchangeability of individual cutters or even of the part casing itself, both the cutters and the part casing are fastened on a demountable frame which can be fastened to the crosspiece running transversely to the harvesting machine via simple locking elements.

Inventor: HAKANSSON JAN TORSTEN
IPC: B65B61/20
Filed: 1988-07-15
Abstract: An apparatus for delivering in strip form packaged drinking straws, includes a device for severing the strip on a pivotal drum. The severing device pivots to transfer the individual packed straws to a vacuum cylinder, which is intermittently pivotal to pick up the individualized straws from the drum, and transfer the individual straws to a conveyor section. The conveyor section includes a continuous loop of track having an upper linear section of track and a lower linear section of track. A plurality of pressure arms are connected to the track where, each contains a vacuum holding mechanism adjacent to a free end for retaining the individual straws. The vacuum cylinder is mounted to a slide mechanism which is translatory relative to the upper linear section of the continuous track to position the individual packaged straws on the pressure arms of the conveyor mechanism. The pressure arms are pivotally controlled to pick up the individualized straws when the pressure arms are moving along the upper linear section and, when in the lower section of track, to position the straws adjacent to continuously moving containers to which the individualized packaged straws are attached.

Title: Mains converter for a multi-system, multiple-unit train
Inventor: WALDEN PETER DIPL ING
IPC: B60L9/30
Filed: 1988-07-30
Abstract: It is intended to specify a circuit arrangement for a mains converter of a DC voltage intermediate circuit converter on a multiple-unit train, which mains converter can optionally be connected to an AC voltage network or to one of two DC voltage networks of different voltage amplitude, by means of which circuit arrangement as few semiconductor switches (especially GTO thyristors) as possible are used in an optimum manner for different types of voltage. To this end, two bridge circuits (which operate as four-quadrant controllers during AC voltage operation and consist of in each case four semiconductor switches (T1 to T4 and T11 to T14) which can be switched off) are connected in series with freewheeling diodes (D1 to D4 and D11 to D14), which are in each case connected in reverse parallel, with their AC voltage connections being isolated, are connected to the higher mains DC voltage and are operated as two-quadrant controllers. In the case when the supply is provided from the lower mains DC voltage, the arrangement can be switched over to a step-up controller. <IMAGE>

Patent DE-3924742-A1 (DE)
Inventor: BILZ GEORG
IPC: B22D15/02
Filed: 1989-07-26
Abstract: The invention relates to a low-pressure chill casting process for producing metal castings, e.g. cylinder heads or engine blocks of internal combustion engines or the like, the walls of which are much thinner in some areas than in others. In this process, pressurized gas forces molten metal out of a melting crucible through a rising pipe into a mould. The mould is arranged so that the thicker wall of the casting is cast in the upper part of the mould remote from the gate and the thinner wall is cast in the lower part of the mould near the gate. The molten metal is introduced into the mould cavities that form the thinner wall at or near the lower region of the mould. The molten metal can be introduced into the mould cavities that form the thinner wall of the casting through a base runner at several gates in the lower, gate region of the mould.
