C., and an ultraviolet stabilizer, and then curing said film by heating it to a temperature above 70.degree. C.; coated shaped articles made by this method.
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. The entry of a first entity for the definition of the switching cycle is limited to a time interval between the actual time and the end of a pregiven first program range, in which upon the entry of the entity switching cycle-start or switching cycle-end there is set with the first input pulses the present entity to a starting value most closely to the present limit of the first program range but within the first program range, and wherein upon the entry of an input pulse with an associated setting direction which would set the value of the present entity outside of the first program range, causes this input pulse to be rendered ineffective or to selectively erase the present entity.
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:
The present invention relates to a concentrator for concentrating solar radiation and to the production thereof from polymeric materials. The concentrator according to the invention can be used in photovoltaically or in particular in solar thermally usable systems. The concentrator according to the invention allows for the efficient concentration of solar radiation onto objects such as solar cells, independent of the geometry thereof. This relates, for example, to the surface of a solar cell as it is used in concentrating photovoltaics, and also an absorber tube as it is used in concentrating solar heating, for example in the scope of the parabolic trough technology.
Abstract:
A method and apparatus for monitoring the state or condition of charge of a battery which supplies a plurality of electrical consumption devices in an electronic circuit. A consumption device is operatively connected to a series of counters so that the count condition charges in response to a pulsing rhythmic cycle by one of a plurality of numerical values toward a final count condition, in which the numerical values are specific in relation to the power consumptions of a plurality of electrical consumption devices, and that a signal is generated upon the reaching of a final count condition.
Abstract:
An electronic timer, preferably a kitchen range timer, which includes a control circuit, a display area, input elements, and a switching arrangement which selectively connects an appliance (auto mode) which is operable through the timer directly with a current supply (manual mode). The control circuit is switched into the auto mode through the input of at least one complete switching term, whereby after traversing of the switching terms in the control circuit, the latter is switched into a wait-mode, wherein the appliance which is already separated from the current supply, remains separated from the current supply, and wherein the control circuit which is connected in the wait-mode is switched back into the manual-mode upon the actuation of the manual input element which is provided for this purpose.
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.
