Title: Sewing machine stop system - has selector and sensor to control motor current and brakes to stop needle at the required position
Inventor: KRUEGER MICHAEL DIPL KFM
IPC: D05B69/24
Filed: 1977-08-26
Abstract: The system to stop and hold a sewing machine in a preselected position uses a selection switch to determine the setting of the needle when at rest. When the current to the electric drive motor has been disconnected, a sensor registers a marking on a moving part to determine its speed. The proportional movement speed time is compared with a predetermined time scale, and the operating current is reactivated if the measured time falls short of requirements. The current is switched off by the control unit when the marking reaches the preselected position and is registered there by the sensor. The system reduces the amt. of time needed to bring the sewing machine to the required stop position and eliminates the need for any manual positioning.

Patent DE-2803978-A1 (DE)
Inventor: MEIER JOHANN
IPC: G01G7/04
Filed: 1978-01-30
Abstract: The scales have an electrically controllable weight operating system (9) for optionally attaching and removing operating weights (8a) on or off the pan support arrangement (2), which act on the pan support arrangement (2) in a manner opposed to the counterweight (7) and are graded with respect to one another, and an evaluation circuit which is electrically connected to the measuring arrangement (12, 13, 14). Said evaluation circuit is designed such that after readjustment of the pan support arrangement (2) into its initial position it actuates the weight operating system (9) in such a way that the weight to be measured, which acts on the pan support arrangement (2), is compensated as accurately as possible with the aid of the operating weights (8a) in conjunction with a reduction in the force compensation exercised by the solenoid system. The solenoid system (12, 13) is then switched over in such a way that the entire measurement range of the measuring arrangement connected to the measuring coil (12) is spread to the smallest possible operating weight gradation by comparison with previously in order to achieve the highest possible measurement accuracy. The weight difference still present and to be found within the latter is now established by means of the measuring arrangement with an increased measurement accuracy, the residual weight difference thereby determined is added to the weight component previously balanced by means of the operating weights, and the total weight thereby obtained is displayed. <IMAGE>
