Patent DE-19749825-A1 (DE)
Title: Opening system for plastic bags lying scale-like on top of each other and fed to opening station adhered to two carrier bands
Inventor: MAYER BERND
IPC: B65B43/30
Filed: 1997-11-11
Abstract: The pneumatic opening system comprises an opening head (16) with one or more suction heads (18) which move perpendicular to the supporting face (14a) and initiate lifting of the second bag wall (3). A gripper (19) on the opening head swivels around an axis (20) on the opening head parallel to the bag opening edge and after starting to lift the second bag wall is pressed onto its inner side to clamp the bag wall between the gripper and suction head. A horizontal feed strip for the carrier bands (4) and bags has a transverse rail (14) at the end whose underside (14a) forms the bag supporting surface. The opening head (16) moves vertically from below onto this surface and the suction cap (18) is positioned close to the opening edge of the front bag. Two bag opening spreading plates (25) are mounted on a slide moving towards the bag opening and are perpendicular to a supporting surface on the slide for the material for filling the bag. The spreader plates are inserted into the bags and opened out by scissor action levers.

IPC: B66C13/18
Filed: 1998-01-12
Abstract: A control arrangement for a hydraulic motor, which is, at least in one working direction, loadable by an external force, with a control valve (3) having in this working direction an inflow control throttle (5) in an inflow path (6), and a return control throttle (7) in a return path (8). Further, a load retaining valve (10) is arranged in the return path (8), which is loaded in the closed position by its outlet pressure (PF) and a spring (11) and in the opening direction by the motor inflow pressure (PA). Besides, means are provided for increasing the pressure drop between load retaining valve (10) and tank connection (T) to a value higher than the pressure drop between pump connection (P) and inflow motor connection (A).

Title: Proportional hydraulic valve controlling sliding drilling head driving horizontal boreholes
Inventor: UETTMANN FRANZ-JOSEF
IPC: E21B19/086
Filed: 1998-01-30
Abstract: The operating lever (3) pivots in two directions to advance and retract the drilling head on its carriage. A reversible stop component (7), limits the maximum excursion of the lever at its end positions. The stop has two opposite settings.   An Independent claim is included for the method of control. The stop is set for full volumetric flow when retracting the drilling head. During drilling, the volumetric flow to the feed unit is limited, hence more flow is available to other units of the drilling equipment. Preferred features: The lever is manually operated by pivoting. The stop component has an asymmetrical toe, or else a system of one or more asymmetric washers. Its bore fits onto the shaft of the operating lever, allowing it to be rotated around the shaft. It is located in the recessed guide frame (8), which includes adjustable stop screws (9, 10), for fine setting of the lever end positions. Spring-loading (12) locks the stop component in set positions. The curved guard (11) is used to lift, rotate and reset the stop in the required position.

Title: Procedure for recognizing failure of phase of converter- controlled three phase induction machine
Inventor: KRIETEMEIER JUERGEN
IPC: H02H7/08
Filed: 1998-04-17
Abstract: A procedure for recognizing the failure of a phase of a converter-controlled three phase induction machine has monitoring of at least two phase currents in each monitoring stage of a monitoring circuit, which generates a trigger signal for the state of being below a threshold value for the concerned monitoring stage. In a first monitoring state in each monitoring stage, the instantaneous value of the phase current is compared with the threshold and during its state of being below, the trigger signal is generated. After that with a trigger signal waiting for attention, there is change from the first into a second monitoring state and in this state the duration of the trigger signal is compared with the angle swept by the voltage vector of the phase turning with the rotating field. With the waiting for attention of the trigger signal over a specified rotating field angle, there is change over into a third monitoring stage. Here the waiting for attention of the trigger signal during a defined delay time interval is tested and with its survival, phase failure is announced by the trigger signal.
