Patent CH-646574G-A3 (CH)
IPC: H02P8/02
Filed: 1980-07-14
Abstract: An electronic timepiece having a stepping motor includes a power source, an oscillating circuit, a dividing circuit connected to the oscillating circuit, and a wave shaping circuit receptive of a plurality of output signals produced from the dividing circuit to produce a plurality of controlling signals. A controlling circuit receives the controlling signals and controls a driving circuit. The power source is connected to a detecting voltage circuit by which the variation of the supply voltage of the power source is detected, and a normal waveform or an intermittent waveform is selectively applied to the stepping motor according to the variation of the supply voltage. As a result, the power consumption of the steppng motor is controlled at a constant level, even if the supply voltage of the power source is higher than the optimum voltage of the stepping motor and even if the supply voltage varies.

Date May 27, 1993In a plastic clip which serves to close sausage casings, bags or the like and consists of two interlockable parts (1, 10), at least one part (1) consists of an elongate frame, which has side bars (2), which have a large height in relation to their wall thickness. The side bars (2) are provided with central recesses (4), into which the end of the wrapper, which end has been gathered to form a tip, can be inserted. The other part (1; 10) together with the first part encloses the wrapper and that has been gathered to form a tip. At least the other part (1; 10) is provided with a projection, which consists of a rib (13), which extends parallel to the side bars and protrudes into the interior (5) of the frame. That projection deflects the tip in wave shape and applies pressure to the tip at the same time. For this reason, the clip will have a maximum elastic yieldability and, as a result, a maximum adaptability to different tip thicknesses or different pressures in the closed interior space in conjunction with a strong and uniform seal whereas the firm detent connection is not adversely connected. In a first embodiment the two clip parts are identical. In a second embodiment the first part encloses the tip by a U-shaped recesses, which are formed in the side walls and closed by the second part.
