Abstract: Method and Apparatus for Controlling an Hydraulic Cylinder Abstract Automated control apparatus for an intermittently extended hydraulic cylinder is disclosed which governs cylinder elongation such that the rate of elongation is essentially constant with respect to time.  The control apparatus includes a preset continuously variable timer that regulates the timer interval between sequential length increments of the cylinder.  The control apparatus also includes a second timer which is responsive to the timer interval interposed by the first timer and which operates a valve controlling communication of hydraulic fluid between a hydraulic cylinder and a pump.  The second timer may be discretely variable so that one of a plurality of predetermined length increments can be selected.  Alternatively, the second timer may adjust the time period during which the valve is opened such that successive stages of a telescopic hydraulic cylinder have equal length increments.

Abstract: Procédé et dispositif pour identifier des objets marqués par bande ou fil magnétique mince.  On utilise un procédé de détection du passage d'une bande magnétique dans une zône de détection.  Cette zône comporte au moins un cadre avec une bobine d'excitation alimentée en courant alternatif pour créer un champ magnétique alternatif, et une bobine détectrice équilibrée de telle sorte qu'aucun signal n'apparaisse en l'absence de corps magnétique à proximité du cadre.  Le passage à travers ou à proximité du cadre d'un objet portant une bande magnétique engendrant, à chaque alternance du champ d'excitation, un déséquilibre dans la bobine détectrice, fait apparaitre un signal qui est appliqué à un dispositif de détection et de mesure de phase par rapport au champ d'excitation.  Pour attribuer une réference codée à un objet on laisse la bande magnétique intacte ou on la sectionne sélectivement en des emplacements variables prédéterminés et par des coupures d'importances variables prédéterminées.

Abstract: ABSTRACT OF THE DISCLOSURE         The subject of the invention is a process for the pro-duction of coatings from polyhydroxy compounds, based on copoly-mers containing hydroxyl groups, and polyisocyanates in solvents having no active hydrogen atoms, by shaping whilst removing the solvent.   The copolymers which are used according to the invention give lower viscosities than the known copolymers.  These less viscous copolymer solutions exhibit a better absorption of pig-ment both when using inorganic or organic pigments.  The reactive lacquer manufactured therefrom produce high-gloss films.        The films of the reactive lacquers used in the process of the invention have the following advantages:  better resistance to solvents, higher abrasion resistance and better resistance to weathering in the Florida climate.  In addition, the copoly-mers used according to the invention, when combined with poly-isocyanates and diluted as described give lacquers of higher solids content.        By the invention, an acrylic resin is provided, contain-ing hydroxyl groups, which, in combination with polyisocyanates, gives the binder foundation for air-drying lacquers and also stoving lacquers which are suitable for top coats of lacquer in the automobile industry; the top lacquer being located directly on top of the stove? primer of electro-coating lacquer or another suitable primer.

Abstract: ABSTRACT OF THE DISCLOSURE           A method of recycling the off gas from an ozone disinfec-tion step used with an activated sludge waste water treatment sys-tem, and apparatus for carrying out the method.  The moisture is removed from a substantial portion but not all of the ozonation off gas, while the nitrogen and carbon dioxide contaminants that are contained in the off gas are left in it.  The dried off gas is mixed with oxygen enriched gas from the original source, and the resulting mixture is delivered to the ozone generator for the pro-duction of more ozone.  Another portion of the ozonation off gas is diverted upstream for introduction into the oxygen treatment facili-ty of the activated sludge treatment plant.  The drying of the ozon-nation off gas is preferably carried out by use of a two cycle self-purging dryer, with the portion of the ozonation off gas that is not delivered as a recycle component to the ozone generator utili-zed as the purge gas for the dryer before it is recycled upstream.

Abstract: ABSTRACT OF THE DISCLOSURE           Although it is known to produce images, writings or drawings by the use of conventional chalks and crayons, such images cannot be permanently fixed by simple means.  Therefore, enamels are sometimes used to produce a permanent image.  How-ever, such enamels are expensive and require firing at high temperatures.  The present invention overcomes these problems by providing a drawing and painting stick, in the form of school chalk, for producing images adapted to be fixed by the use of heat.  By means of such a stick, images, writing, drawings, and the like may be produced in the usual manner upon a base and then be permanently fixed by the application of moderate temperatures.  Thus, the drawing and painting stick according to the invention allows the user to produce designs or drawings as if conventional chalks were being used, and then to fix them permanently, very quickly and simply, so that they adhere firmly and are impact-resistant.  The stick comprises a major proportion of a thermoplastic or heat-curable thermosetting synthetic resin composition together with colouring matter including at least 5% by weight of the stick of pigment.

Abstract: ABSTRACT OF THE DISCLOSURE   A burner control system includes a pump for supplying pressurized fuel through a fuel line and a signal-responsive flow valve to a burner nozzle. Also in the system is an ignition control circuit which includes an igniter operable in response to a first signal in the circuit to ignite the fuel,  A flame-detecting cell in the circuit causes the termination of the first signal so as to deactivate the igniter when combustion occurs.  A second or auxiliary circuit operatively connected to the ignition control circuit includes a first switch responsive to the first signal in the ignition control circuit to cause a second signal to be transmitted to the flow valve for opening the valve to allow pressurized fuel to flow to the nozzle,  A second switch in the second circuit serves as an alternate circuit for transmitting the second signal to the flow valve,  The second switch is responsive to the pressure of the fuel in the line so that, in the absence of the first signal, the second signal is transmitted to the flow valve only as long as the fuel pressure is main-tained above a predetermined high pressure.
