Abstract: ABSTRACT OF THE DISCLOSURE           The invention relates to valve type spout for a fluid container, especially for a pouch worn by a patient to collect fluid discharged from a surgically formed stoma at his abdominal wall.  Heretofore, such valve type spouts have been rigid in construction and of uniform circular cross-section, their outlet ends being closed by removable valve caps.  They suffer the disadvantages of becoming clogged during emptying, of having cap removal difficulties, of being without effective control of fluid drainage and of not readily accommodating attachment to external drains.  These disadvantages are overcome by the invention, according to which the spout is flexible as has an inlet neck section of oval cross-section, to facilitate clamping thereof between the user's fingers to close the spout before the cap over the outlet end section is removed, thereby assuring control of the discharge through the spout.  A flexible tubular coupling member for feeding an external collection unit readily attaches to the outlet end section and provides lea-proof connections with striations or mating ridges.

Abstract: ABSTRACT OF THE DISCLOSURE Water-in-oil emulsions of polyacrylamide or other water soluble vinyl addition polymers having amide functionality can be reacted with form-aldehyde and a secondary amine containing 2-8 carbon atoms followed by quat-ernization to prepare water-in-oil emulsions of quaternized cationically mod-ified polyacrylamides.  The resultant water-in-oil emulsions are stabilized against cross linking by the addition to the water-in-oil emulsions of an aqueous solution of a water soluble phosphorous compound having a P-H bond. The phosphorous containing compound is added in such a quantity so as to pro-vide from 1.6-25% by weight of the phosphorous compound based on the weight of the polymer contained within the water-in-oil emulsion and to simulta-neously adjust the pH of the water-in-oil emulsion to a range of between 3.5-5Ø  The stabilized water-in-oil emulsions can be readily inverted into aqueous solution causing the solubilization of the polymer in the aqueous without the need for heating the water-in-oil emulsion at high temperatures for extended periods of time.

Abstract: TITLE:  CHILD-RESISTANT CLOSURES FOR CONTAINER MOUNTED         SPRAY DISPENSERS            ABSTRACT OF THE DISCLOSURE:  A child-resistant safety closure is provided for closing the outlet of a hand-operated fluid product sprayer dispenser used on a con-tainer to prevent leaks from the container during periods of non-use and to resist accidental use by children or unwary adults.  The closure cannot be moved from an "outlet closed" position to an "outlet open" position without the performance of at least two discrete, predetermined definite actions by the user to first disable a lock and then to linearly or rotatably move the cap into the "outlet open" position to permit spraying or dispensing.  A closing member is connected to the bottom portion of the sprayer for re-movably mounting the sprayer to the container and closing the same. The member and the sprayer to which it is con-nected cannot be removed without the performance of at least two discrete, predetermined definite actions, which actions are difficult if not impossible for young children to per-form.

Abstract: Abstract Gated Baseline Corrector Input pulses are coupled through a delay network to a pulse amplifier.  The amplifier includes feedback circuitry for correcting its output to a particular baseline level, generally zero volts.  Within the amplifier feedback path is a gate, which is normally closed.  Input pulses are also coupled to a pulse detector; whenever an input pulse is detected, the baseline gate in the amplifier feedback path is open, and the dynamic feedback operation is temporarily inhibited.  During this time, the most recent previous level of baseline correction is retained.

Abstract: ABSTRACT:     A circuit for rapidly resynchronizing a clock with an external clock. The clock to be synchronized obtained at the output of a phase-locked loop by divid-ing the frequency of a reference clock in a frequency divider whose division factor is controlled by a phase controller detecting the deviation between the trans-itions of the two clocks to be synchronized. According to the invention, the pulses of the reference clock are applied to the phase-locked loop by means of a gate, connections having been provided to render this gate non-conductive by means of the characteristic transition of the clock to be synchronized which follows the appearance of a resynchronizing control signal, and for thereafter rendering this gate conductive by means of a character-istic transition of the external clock.  Used in data transmission.

Abstract: Abstract A process for purifying waste or industrial water containing hydrocarbons, comprising the filtration of the water in at least one filter formed from a granular material, the process comprising alternately a fil-tration phase and a counter-washing phase of each of the filters with water, this second phase being intended to remove from the filter the impurities retained thereby during the filtration phase, wherein, during the filtration phase, the water charge to be purified has an anionic polyelectrolyte added thereto before passing over the filter.            The incorporation of such polyelectrolytes into the water improves the process efficiency compared with known filter systems of this type.

Abstract: Abstract:     Faulted transistors in a voltage source transistor inverter are protected against shootthrough fault current, from the filter capacitor of the d-c voltage source which drives the inverter over a d-c bus, by interposing a small choke in series with the filter capacitor to limit the rate of rise of that fault current.  At the same time and in response to a shootthrough fault, a pre-charged capacitor, included in a crowbar circuit connected across the d-c bus, discharges through the faulted transistors in a direction opposite to the fault current in order to effect fast turn-off of the transistors, thereby preventing damage thereto.

Abstract: Abstract of the Disclosure A method for recovering a metal from a solution containing ions of the metal and a complexing agent for the ions is disclosed.  The method involves contacting the solution with another metal more electropositive than the metal to be recovered in order to bring about a metal-metal exchange reaction which will yield a precipitate of the metal to be recovered.  The precipitate is then separated from the solution.  In order to maximize the yield of the solution is measured during the course of the reaction, and the precipitate is separated from the solution as soon as the redox potential substantially reached a predetermined minimum value.

Abstract: ABSTRACT Disclosed is a circuit arrangement for the operation of a plurality of opto-electronic display elements such as light-emitting diodes to display for example the exchange and/or operating states in a telephone system, whereby the display elements are arranged in a matrix and may be operated via the matrix drive lines.  The display elements are wired in such a way that there is a lower current consumption with the same operation via the matrix drive lines as compared to prior art arrangements.  With the simultaneous operation of display elements in different matrix columns, these display elements are connected in series and with the use of the display elements from only one matrix column or with no display through a current limiter the appropriate terminating im-pedance is produced for the distant current supply of the display element.  This results in the advantage that for the series connection of two display elements, one display element already represents a part of the series resistor otherwise necessary for each display element.  For the partial operation of the display element with lines of different lengths an optimum input resistance for the current supply via the subscriber line is also given.

In a particular aspect, the output measurement signal of the instrument is solely dependent upon the value of a desired measured variable,  which is representative of a process condi-tion, and is independent of other variables.  The resonant device is coupled to excitation and detection circuitry located at the central control station and produces in the detection circuitry when excited with a pulse of energy first and second signals, one of which is dependent upon the desired measured variable and a second variable and the other dependent upon at least the second variable.  These two signals are then combined according to known mathematical and physical principles to produce an output depend-ent upon the value of the desired variable.
