Abstract: ABSTRACT          PURIFICATION OF BORON-CONTAINING SULFURIC ACID           Sulfuric acid contaminated with boron and fluor-ide values such as the waste acid of a boron trifluoride process is purified by contacting the contaminated acid with an inert gas to desorb boron trifluoride, and the inert gas is stripped by contacting with an absorbing liquid including concentrated sulfuric acid.  Fluosulfonic acid is added to contaminated sulfuric acid at levels approximately three times the molar value of boric acid contaminant as an agent to spring non-volatile boron values.  The absorption of boron trifluoride into the absorbing sulfuric acid is improved when it contains boric acid.  Preferably the contaminated sulfuric acid to be purified is one portion of the waste liquid and the absorbing liquid is another portion of the waste liquid of a boron trifluoride manufacturing process.  Boric acid is added to the absorbing liquid, then boron trifluoride is stripped from the inert gas and absorbed into the absorb-ing liquid.  The absorbing liquid along with stripped boron trifloride is recycled to a boron trifluoride manufacturing process.  The inert gas can be recycled to the desorbing step.

Abstract: CODE SENSING SYSTEM            Abstract of the Disclosure:          A transition code processing system which includes a record member on which is located a plurali-ty of bar code symbols, each of which comprises a data channel and a clocking channel.  The record member is inserted into a data terminal device and intermittently driven through a printing station in which a sensing member senses the data channel out of phase with the sensing of the clocking channel and generates signals in response thereto.  A circuit coupled to the sensing member will process the generated signals and transmit the processed signals to a utilization device.  Upon processing the signals representing the last bar code symbol on the record member, the circuit will generate a control signal for stopping the movement of the record member through the printing station, thereby conditioning the record member for a subsequent print-ing operation.

Abstract: ABSTRACT OF THE DISCLOSURE        Disclosed is a process for the preparation of aromatic hydroperoxides comprising contacting two liquid phases comprising an oily phase containing an aromatic compound having a secondary alkyl group and a basic aqueous phase under agitation with a molecular oxygen-containing gas in the presence of a copper compound catalyst such as an inorganic salt or organic acid salt of copper, thereby to oxidize the aromatic compound to a corresponding aromatic hydroperoxide, wherein the liquid phase catalytic oxidation is carried out while maintaining the catalyst concentration in the liquid phases at 0.005 to 10 ppm as the copper atom and the pH value of the basic aqueous phase at 7.6 to 10.  According to this process, by adoption of the above-mentioned specific catalyst concentration and pH value in combination, the rate of oxidation of the aromatic compound is increased and the selectivity to the hydroperoxide is improved.

Abstract: Abstract of the Disclosure A device is provided for detecting the presence of solid impurities within a pressurized fluid.  The device com-prises a housing having a fluid passageway formed therein. One end of the fluid passageway is open to the pressurized fluid while the other end of the fluid passageway is open to a low pressure fluid region via a restricted port.  A filter strip dispensed from a filter strip magazine is disposed across and obstructs the fluid flow through the passageway at a point intermediate its ends so that the filter strip removes solid or liquid particles from fluid flowing through the passageway. A differential pressure sensing means, such as a differential pressure transducer, communicates with the fluid passageway and detects the differential pressure across the filter strip. An increase of fluid pressure sensed by the differential pres-sure sensing means is indicative of a clogged filter strip which in turn, indicates the presence of solid impurities within the pressurized fluid.  Appropriate indicating means to provide a signal upon the occurrence of a clogged condition of the filter strip.

Abstract: ABSTRACT A power supply provides a low-level DC voltage to DC load circuits by first rectifying the standard AC voltage and thereafter reducing the recti-fied AC voltage to the low-level DC voltage.  The reduction of the rectified AC voltage to the low-level DC voltage is accomplished by a power transformer which is switched on or off by a pair of switching transistors.  The switching transistors are operated in a "push-pull" mode by a pair of control transform-ers operating in combination with a control circuit.  The control circuit produces various pulse conditions in the control transformers which turn their respective switching transistors on and off in a prescribed manner.  An over-current sensing and control device prevents damage to components. A power on/fail circuit signals the load as to the status of the regulated load volt-age and guarantees power for orderly shutdown after an input power outage.

Abstract: Abstract of the Disclosure Disclosed is a semiconductor integrated circuit device comprising a semiconductor chip including a plurality of elements constituting multi-functional circuits and a control signal generating circuit incorporated within the semiconductor chip.  The control signal generating circuit includes a variable resistance element which irreversibly changes its resistivity when a voltage having a magnitude larger than a specific value is applied to it.  The variable resistance element is connected in series with a fixed resistor which is further connected in parallel with the output electrodes of a field effect transistor.  When it is intended to change the resistance of the variable resistance element a control signal is applied to the input terminal of the transistor and a higher voltage applied to the power supply terminal.  An output terminal connected to the junction of the serial connected elements indicates logical "1" or "O" depending on whether the variable resistance element is in the high resistivity state or low resistivity state.  In the semiconductor integrated circuit, the output of the control signal generating circuit is transmitted to at least one of the multi-functional circuits, so that it is activated or left deactivated.

Abstract: ABSTRACT A method and apparatus are disclosed for storing thermal energy.  A hydroxide of calcium, magnesium or barium is converted in a first container to the oxide and steam by being exposed to solar radiation.  The steam is passed to a holding container and condensed.  In another container capable of communicating with said first container is disposed a solution of an alkali metal hydroxide. When the solar radiation discontinues this latter container is connected to said first container and, at the temperatures obtaining, the vapour pressure above the alkali metal hydroxide is sufficient to cause water vapour to flow into the first container and reconvert the alkaline earth metal oxide to hydroxide, at the same time concentrating the alkali metal hydroxide solution.  When solar radiation recommences the process is repeated eventually affording very concentrated or practically anhydrous sodium hydroxide.  When heat is required in colder weather the water in the holding container is contacted with the concentrated alkali metal hydroxide resulting in an exothermic reaction which can be heat exchanged in conjunction with a water filled central heating system.

Abstract: ABSTRACT:    An improved tool for cutting optical fibers by the scribe-and-break technique is disclosed.  The tool has a scribing edge transversely directed with respect to, and normally spaced from, an arcuate convex fiber supporting surface.  When moved normally with respect to the fiber supporting surface, the scribing edge defines a scribing plane.  Spring members, located on opposite sides of the scribing plane, are compressed between the fiber supporting surface and a bearing surface, causing the optical fiber to be clamped between the  spring members and the  fiber supporting surface.  This compression also forces the spring members to slide longitudinally along the fiber supporting surface away from the scribing plane, imparting an axial tensile stress to the optical fiber.  The optical fiber is finally  scribed by  the  scribing  edge,  resulting  in propagation of a fracture over the cross section.
