Title: Excitation circuit for terminal voltage of DC motor - rectifies voltage proportional to sec. voltage of transformer assigned to converter
Inventor: NIEHAGE HELMUT ING GRAD
IPC: H02P7/292
Filed: 1978-12-15
Abstract: The excitation circuit rectifies the secondary voltage of a transformer on the input side of the static converter that supplies the d.c. motor and uses the result to construct control pulses for the converter's thyristors. The rectified voltage, proportional to the secondary voltages of the transformer, is passed to an amplifier and rectified in accordance with the conduction angle of the converter's thyristors. Several such voltages may be obtained from each transformer in the converter. The advantage lies in reducing the number of components needed to generate a voltage proportional to the motor's voltage.

Patent DE-2902871-A1 (DE)
Title: Shuttleless loom with automatic needle control
Inventor: CAMPRUBI ANSELMO BOLEA
IPC: F16H/
Filed: 1979-01-25
Abstract: On a shutteless loom, a needle control mechanism operates in synchronism with the sley. The mechanism assembly is mounted firmly on the shaft of the sley, and comprises a frame which supports the various elements intended for the transmission of final movement to the needle support strip, or to the weft insertion elements. - The elements, which are driven by a toothed quadrant oscillating on a rotary shaft are precisely displaced by a lever keyed on to the shaft. The head of the lever is either submitted to the direct action of a connecting rod which is motivated at its other end by an eccentric system, or it is driven by a double arm, which is jointed to the connecting rod at an intermediary point. - The oscillation of the sley, by reason of the framework joined to it, which supports the needle control and weft insertion mechanism, provides automatic functioning of the system. The synchronisation of the mechanism is such that, at its furthest forward position, the weft insertion elements are removed from the fabric, and at its further position to the rear, the elements pass through the centre of the fabric.

Title: Cleaning tube nest containing heat exchangers - uses brushes which are mechanically moved through tubes during operation
IPC: F28G1/04
Filed: 1979-12-01
Abstract: The cleaning procedure is for heat exchangers with a nest of tubes, such as surface condensers. Cleaning members, e.g. as brushes, are moved in the longitudinal direction through the tubes.

Title: Expansion joint cover for bridges - has intermediate cross member supported on rubber blocks mounted on cantilevers
IPC: E01D19/06
Filed: 1980-05-03
Abstract: The expansion joint for bridges and similar structures is fitted between the cross member (LRI) of one part of the structure and the cross member (LR2) of the adjoining structure. An intermediate cross-member (L) is mounted in cubic elastomeric blocks (4), which rest on cantilevers (TKI) which project alternately from the two parts of the structure. Relative movement between the cross-members, due to thermal expansion or contraction, is absorbed by shear deformation of the elastomeric blocks. A flexible sealing strip is fitted in the gaps between the cross members. The strip is folded along its centre line as the gap between the cross members is reduced. The elastomeric blocks ensure that the loads are distributed equally over each cross-member.
