Abstract: ABSTRACT OF THE DISCLOSURE:           A process of thermally decomposing bi- or multivalent metals dissolved in an aqueous liquor to form the corresponding oxides and hydrogen  chloride with simultaneous recovery of overazeotropic hydrochloric acid or hydrogen chloride.  The hydrochloric acid recovered by adiabatic absorption from the gases formed by the decomposition is increased in concentration by an extractive distillation in contact with a concentrated metal chloride solution of bi- or multivalent metals.  The metal chloride solution which becomes available as a result of the extractive distillation and is less concentrated than the feed solution of chlorides of bi- or multivalent metals is increased in concentration by a heat exchange with the hot gases formed by the decomposition.  A solution of the chlorides of the bi- or multivalent metal in a higher concentration, thereof at least a part has been in direct contact with the gases formed by the decomposition, is supplied to the thermal decomposition stage at a metal chloride rate which corresponds to the metal chloride content of the incoming aqueous liquor.  The process according to the invention is particularly suitable for processing metal chloride solutions which contain magnesium, aluminum, manganese, chromium, iron, cobalt and/or nickel ions.  Special advantages afforded by the process reside that an overazeotropic hydrochlo-ric acid having any desired concentration. inclusive of virtual-ly pure hydrogen chloride, can be produced as one product of the decomposition process substantially without need for a supply of extraneous energy, and virtually all energy required to increase  the hydrochloric acid in concentration is supplied by the waste heat which becomes available in any case as a result of the decomposition.

Abstract: ABSTRACT OF THE DISCLOSURE          In the frequency measuring system disclosed herein, a control signal is generated which is related to the value of function of the input signal for a selectable delay time.  The average value of the control signal is employed to control the clock rate of a shift register which is used to obtain a delayed version of the input signal, the input signal being digitized and fed into the shift register.  This feedback path forms a servo-loop which adjusts the clocking rate of the shift register in correspondence with the frequency of any coherent component in the input signal, even though the input signal may be a com-posite comprising many random components.

Abstract: Abstract of the Disclosure In a new spraying apparatus the spray dispensers for liquid or finely divided spray material discharge into an enclosure contained within a flexible skirt attached to a sprayer boom. Air under pressure is injected into the skirt which supports the boom from the ground as it is moved over the area to be sprayed. The skirt is formed by one or more flexible air bags into which the air is injected and from which it escapes into the skirt enclosure.  An annular air bag skirt structure is formed by folding inwards the edges of a strip of flexible material and fastening them to the strip in spaced parallel relation to form two parallel tubular passages.  The open ends are then closed by means of respective open-sided envelopes slipped over the ends and laced thereto.

Abstract: 47,673 ABSTRACT OF THE DISCLOSURE         A method is provided for testing induction motors, particularly single-phase fractional horsepower motors, which enables routine testing of all motors in production for both starting and running torque and other desired characteristics.  The method consists essentially of apply-ing power to the motor for a very short period of time, such as three or four cycles of the supply voltage then inter-rupting the power supply and immediately measuring the in-stantaneous speed by observing the induced voltage from the deenergized motor terminals.  The torque then is verified from the change in speed over this short period.  Both starting and running torques can be tested very quickly in this manner by means of solid-state control and computing devices, without connecting anything to the motor other than the power leads.  Other desired characteristics of the motor can also be readily determined.

Abstract: Abstract of the Disclosure For the production of positive photographic prints a composite material in strip form is used as an intermediary to for the print images and is then adhered in a continuous procedure to a main support strip such as paper.   The resultant strip is then cut to separate the individual prints.  The composite material has a transparent film of biaxially-oriented plastics film not more than 50 µm thick and water-resistant and to which photosensitive emulsions are applied, and a further layer overlying the emulsions to protect them, the further layer being adhered to the main support.  This layer is reflective, as by incorporation of a white pigment, so that the image is seen through the transparent film against the background of this layer rather than the main support. The reflective layer may contain other chemicals relevant to processing.

Abstract: ABSTRACT Disclosed is a digital computer system comprising an input data circuit, a processor for executing a program stored in a memory to process the inputted data, a depletable energy source for energizing the elements of the computer system, and a power control circuit for selectively controlling the drain imposed upon the energy source in accordance with the data input into the system and the program executed by the processor.  The power control circuit is operative in at least three modes of operation, namely off/rest, power down, and operating.  In the off/rest mode, the power control circuit energizes a storage element illustratively taking the form of a flip/flop to be receptive to an initialization signal as derived from an on/off switch to dispose the power control system from its off/rest mode to its power down mode.  The storage element is energized throughout the entire operation of the system including the off/rest mode, wherein the remaining elements of the computer system are deenergized.  In the power down mode, the control circuit applies power to the data input means.  The data input means may include a keyboard and a decoder for providing a signal indicative that one of the keys has been depressed. Upon actuation of the key, a data available signal DA is transmitted to the power control circuit, whereby the computer system is dis-posed in its operating mode, wherein all of the elements of the computer sys-tem are energized.  In its operating mode, the processor and its memory are fully energized to execute the stored program.
