Abstract: A method and arrangement for entering a switching program into an electronic timer, in particular a kitchen range timer, wherein the switching program consists of at least one switching cycle within a predetermined time range, preferably within 23 hours and 59 minutes. The switching cycle is timely defined through any two of three entities consisting of switching cycle-start, switching cycle-period and switching cycle-end, wherein the entry is effected serially in the form of sequential input pulses, which have an information relative to the setting direction (forward or backwards) associated therewith, and which is preferably counted in a forward-backward counter arrangement.

Abstract: The invention relates to a process for optimizing the properties of aqueous polymer solutions used for polymer flooding which comprises treating the polymer solutions under turbulent flow conditions in dynamic fluid dispersing or pumping equipment such that the residence time of the polymer solution in this equipment is less than approximately 20 seconds and the pump energy used is from about 1 to about 15 watts/liter of solution processed.This process permits the optimization of flow properties important in polymer flooding which results in the improved efficiency of the polymer flooding process.

Abstract: A power line-operated electronic time-clock including a clock switching circuit, a memory for storage of switching or alarm times, including an input device and a display device, and a power outage-bridging circuit for supplying electrical energy during a power outage to at least the timing components of the clock switching circuit and when required, to the memory storage device. The time-clock includes a monitoring circuit that is interconnected to the memory storage device, and the power outage-bridging circuit for generating a blocking signal in response to the absence of timing data being introduced into the memory device for rendering the power outage-bridging circuit inoperative. Thus, the energy storage device within the power outage circuit will not be drained prior to use or during testing of the clocks.

Abstract: A method and an electro-mechanical arrangement for the generating and processing of electrical impulses for the setting or correction of an electronic digital display through the intermediary of an impulse generator. The impulse generator consists of an impulse transmitter and an impulse collector whereby, by means of the impulse emitter which evidences a plurality of impulse-generating elements, preferably arranged at uniform spacings in a circular path relative to a rotational axis, a plurality of electrical contacts are adapted to be closed in cooperation with the impulse-generating elements. The contacts of the impulse collector, generating mutually timewise displaced but still overlapping impulses whose frequency is proportional to the relative speed between the impulse transmitter and the impulse collector and whose phase position, in essence the phase lead and phase lag, is dependent upon the relative direction of rotation between the impulse transmitter and the impulse collector.

Abstract: In an electronic digital display control device, a pulse generator is actuated to produce pulses which are fed into a counter to control the setting on the display. A discriminator detects whether the frequency of the pulses exceeds a predetermined frequency limit. If the limit is exceeded, the discriminator connects to the counter a second pulse generator which provides pulses at a freqency higher than the predetermined frequency limit. By so doing, the counter receives a substantially greater number of control pulses per unit of time and sets the digital display very rapidly.

Abstract: An adjusting mechanism is disclosed for adjusting a digital indicator of an electronic mechanism, such as a timepiece, which includes a first pulse generating mechanism for normally operating the digital display indicator. A second pulse generator includes a pulse former connected electrically to the digital indicator for supplying electrical adjusting pulses thereto. A sensor is operably connected to the pulse former to deliver activating signals thereto for the production of an adjusting pulse. A pulse control member is operably associated with the sensor to control the delivery of activating signals to the pulse former. Either the sensor or the pulse control member is rotatable relative to the other such that activating signals are generated in response to such relative rotation and are generated at a rate which is proportional to the rotational speed of the pulse control member.
