Abstract: This invention relates to internal combustion burners. In the burners according to the invention, the combustible mixture flows in counter-current to the combustion gases while in contact with the same, and the introduction of the mixture into the combustion chamber is effected along a wall of said chamber and the emitted gases leave the chamber along a second wall thereof, the two walls being opposite one another. The burners according to the invention, which have improved performance and versatility of use, are of use more particularly for mineral fibre drawing processes.

Abstract: In activating a unit for monitoring a remote instrumentality, a tone-responsive circuit operates in accordance with an established duty cycle wherein, for a major portion of each cycle, current is drawn from the telephone lines-servicing the system at a rate which is within the range permitted by prevailing telephone regulations, to charge a capacitor over time, and wherein, for a minor portion of each cycle, the charge stored by the capacitor is used to briefly operate a tone detection circuit which is capable of determining whether or not the remote instrumentality is being interrogated. If no such tones are detected, the circuit continues its periodic operation as previously described. If tones indicating a desired interrogation are detected, the tone-responsive circuit activates the monitoring unit which is used to poll the instrumentality.

Date Dec. 12, 1991.A cooling vessel has a container with an outwardly bent rim and a lid which can be set on the container, as well as a closure device with at least one closure element arranged on the lid, preferably in the region of a rim of the lid. The closure element can swivel about a swivelling axis approximately parallel to an outer edge or to tangent to the outer edge of a rim of the container from an open position which releases the lid from the container into a locking position in which the closure element grips under the container rim, thus forming a pressure-tight seal between the lid and the container. The closure element is designed as a hollow body with an essentially cylindrical or prismatic wall essentially parallel to the direction of the swivelling axis. The wall extends over only a part of the periphery of the hollow body and has a locking wall section which can be pivoted from an open position into a closing position.

Abstract: The mailing envelope has row of oblique cuts in registration with the adhesive area of the back where the corresponding closure flap will adhere, so that in one of the extremities of the row of oblique cuts there is provided a special larger cut with a different inclination, said cut forming a means for initiating the opening of the envelope, by tearing out the aligned oblique cuts, when pulling from the respective extremity of the flap. Likewise, a second special cut provided at the opposite extremity of the row of oblique cuts will form the means to evidence a fraudulent attempt to open the envelope, the reason being that, when pulling from that second flap extremity in order to try to separate it from the back of the envelope, a tearing is produced in the transverse direction to the envelope. Both the oblique cuts and the extreme cuts for initiating the opening and tamper evidencing, are applicable to envelopes with straight, trapezoidal or triangular flaps. <IMAGE>

As entradas para as passagens de gás de combustão (11) e as saídas de passagens de gás de combustão (12) através das quais um gás de combustão, tendo uma taxa de fluxo de volume maior passa, são formadas em um lado longo de ângulo e suas entradas de passagens de ar (15) e saídas de passagens de ar (16), através das quais um ar tendo uma taxa de fluxo de volume menor passa, são formadas em um lado curto de um ângulo. Consequentemente, é possivel evitar um aumento na perda de pressão causado por uma diferença de taxa de fluxo de volume entre um fluido em alta temperatura e um fluido em baixa temperatura, a fim de reduzir a perda de pressão em todo o permutador de calor.
