Abstract: ABSTRACT OF THE DISCLOSURE:        This invention is concerned with a method for breaking stabilized emulsions, which method advantageously distinguishes over the prior art methods in that it does not require the addition of pH correcting but polluting substances. This method comprises (a) a first step of breaking of said emulsions, during which the emulsion is passed through by electric currents generated by two series of preferably metal electrodes immersed in said emulsion and connected to the positive pole and the negative one respectively of a direct current generator; (b) a second step of agglomeration of the floculated particles; (c) third step of separation of the agglomerated particles from the depurated water. This inven-tion is also concerned with an apparatus for carrying out the above mentioned method.

Abstract: ABSTRACT OF THE DISCLOSURE       There is provided an air-ventilating device for use in ink-jet printers.  Ink is supplied from a reservoir to a plurality of printing jets, each of which communicates with an ink-distributing device.  The device has the form of a riser and communicates at substantially its highest point with a ventilating passage of such diameter as to pro-vide a capillary effect.  The passage conveniently communicates with an ink-collecting chamber, which in turn communicates with a drain.          Such an air-ventilating device enables air to bled from the system with the minimum of effort and with the absence of moving, auxiliary mechanical devices.

Abstract: Abstract of the Disclosure A system to safeguard an automatic fuel vending filling station from fraudulent use, by automatically preventing the delivery of more fuel than a predetermined monetary value.  The amount deposited in the cash box (as determined by a conventional money tester) is communicated to a registration structure via a logic network having an input for each pump outlet or nozzle.  Each such input is connected to a pulse generator driven by a volumetric device at the respective outlet for receiving counting pulses therefrom at a cadence proportional to the rate of fluid dispension, advantageously with interposition of a calculator converting the dispensed fluid quantity into its monetary equivalent.  The registration structure controls a first circuit breaker for de-energizing all pumps upon being counted down to zero by the logic network in response to the counting pulses, the logic network having an output connected to a pre-settable counter for transmitting thereto a train of pulses corresponding to a monetary amount deposited in the cash box with the aid of an electrically driven money feeder.  The presettable counter controls a scanned circuit breaker for de-energizing the money feeder as soon as the deposited amount equals the setting of this counter, thereby preventing the filling station from handling more than a certain amount of cash at a time.

Abstract: IMPROVEMENTS IN OR RELATING TO AUDIO FREQUENCY               AUTOMATIC MUTING ARRANGEMENTS          ABSTRACT OF THE DISCLOSURE         In an automatic audio frequency muting arrangement, intelligence and noise signals in a received audio frequency signal are detected and the levels of the detected intelligence and noise signals are compared.  The result of this comparison controls a muting switch in the audio frequency path.  The intelligence signals are detected by a capacitive time constant circuit which is of relatively short time constant, and the noise signals are detected by a capacitive time constant circuit of relatively long time constant.  The time constant capacitor for noise signal detection can be isolated from the input during those times in which intelligence signals are present in the received audio frequency signal.

Title: Stable hectograph compositions, transfer elements and  processes

Abstract: STABLE HECTOGRAPH COMPOSITIONS, TRANSFER ELEMENTS AND PROCESSES                     Abstract of the Disclosure Solvent hectograph compositions which are resistant to rapid thickening and gelling during storage in the presence of ambient humidity comprising a cellulose ether film-forming binder material, at least one oleagineous material which is substantially incompatible with said binder material and a major amount by weight of particulate spirit-soluble solid hectograph imaging material, the volatile solvent for said binder material being a lower aliphatic ester which is a sub-stantial non-solvent for said imaging material and which has a partial miscibility with water, the process of making such compo-sitions and the process of producing pressure-sensitive transfer elements from said compositions.       Solvent hectograph compositions and pressure-sensitive transfer sheets coated therewith have been proposed for several years as replacements for the more conventional hot-melt hecto-graph compositions and transfer elements.  Such solvent composi-tions include resinous binder materials in place of wax binder materials, and volatile organic solvents as vehicles to maintain the compositions at a suitable viscosity for coating onto a flex-ible foundation such as paper or plastic film.  Reference is made to U. S. Patents 3,177,086 and 3,767,450 and to British Patents 833,631 and 973,362 as representative of various solvent hecto-graph compositions and transfer elements.       Among the problems encountered with prior-known solvent hectograph compositions are the government regulations which now preclude or restrict the use of certain volatile solvents as dangerous to the health of workers, such as the chlorinated aliphatics, or as pollutants to the atmosphere, such as aromatic hydrocarbon materials including toluene and xylene. However, a more technical problem over the years has been the instability of solvent hectograph compositions based upon cellulose ether binder materials whereby such compositions under-go an increase in viscosity and become gelled after a fairly short period of time, frequently one or two days, so that they are no longer coatable.  Thus, they had to be prepared in small batches capable of being used immediately, and the coating pro-cedure could not be interrupted for long periods of time for equipment repair without possible gelling of the composition in the ink pan on the apparatus.  Their poor shelf life is caused by the absorption of ambient moisture from the atmosphere, which moisture apparently causes a swelling and thickening of the cellulose ether binder material and/or a plasticizing action between the oily ink vehicles and the binder material.

Abstract: ABSTRACT OF THE DISCLOSURE:            A dummy or starter bar for starting a strand in a continuous casting installation having an open-ended mold is pro-vided with a head which is receivable in the mold.  The dummy bar head has a peripheral surface which faces the inner surface of the mold.  The dummy bar head further has an end face at least part of which is inclined with respect to the peripheral surface.  The end face is directed towards the inlet end of the mold.  The dummy bar head is provided with a dovetail-like recess which opens to the in-clined part of the end face.  The recess enables the strand to be-come coupled to the dummy bar head and is arranged so that coupling occurs in a manner which permits the strand and the dummy bar head to become detached by relative movement thereof in a direction trans-verse to the longitudinal axis of the strand.  The recess is bound-ed so as to prevent penetration thereof into the peripheral surface of the dummy bar head and this, in conjunction with the inclination provided for the end face of the dummy bar head, enables the dummy bar head to be readily sealed in the mold.  A method of starting the strand involves placing bars of chill material in the recess in such a manner that they are inclined with respect to the inner sur-face of the mold and that the ends thereof are located in the under-cut section of the recess.  The molten material introduced into the recess solidifies about the chill bars.  The latter serve as an an-chor within the solidifying mass thus providing an enhanced connec-tion between the dummy bar and the strand in the first few critical moments of withdrawal of the strand from the mold.
