Abstract: Case 72-10849 Canada PROCESS FOR THE THERMAL COMBUSTION OF WASTE GASES AND THERMAL      AFTER-BURNING PLANT FOR CARRYING OUT SAID PROCESS     ABSTRACT OF THE DISCLOSURE            A process for the thermal after-burning of waste gases containing combustible substances capable of forming an explosive mixture with air in a specific concentration range comprises feeding the waste gas undiluted to a flame with a concentration of combustible substances which varies between the lower and the upper explosion limits, feeding the waste gas to the combustion zone at an entry speed higher than 10 m/sec, and discontinuing the supply of waste gas when a limit temperature of 80°C is exceeded in the waste gas shortly before its entry into the combustion zone. An after-burning plant for carrying out the aforesaid process comprises a combustion chamber having a burner and a feed pipe for fuel, which latter is preferably gaseous or liquid, a waste gas feed line for introducing waste gas of the above described kind into the combustion chamber, and safety means for preventing the flame penetrating from the combustion chamber into the waste gas feed line, which safety means comprise (a) a dry detonation safety device which is provided in the waste gas feed line upstream of its entry into the combustion chamber, (b) a temperature control device and (c) at least one quick-acting gate valve which is biult into the waste gas feed line upstream of the detonation safety device and which can be closed by delayed action by the temperature control device.                            -la--

Abstract: 19.01 ABSTRACT OF THE DISCLOSURE          The invention relates to an improved form of vacuum-operated printing cylinder for a printing press, providing a practical means for holding the printing plate on the cylinder by vacuum alone, without requiring separate adhesive means and/or supplementary mechanical devices for clamping the plate.  The cylinder includes a supporting shaft mounting, between its bearing portions, a plurality of cylinder supporting rings.  A cylinder sleeve is supported by the rings and forms, together with the rings and the supporting shaft, a hollow cylinder structure having a plurality of vacuum chambers.  The interior of the cylinder can be evacuated from one end of the shaft, and independently controllable valve means are built into the cylinder, to enable the several chambers thereof to be independently evacuated.           The cylinder sleeve is provided with a large number of radial passages, providing communication to the outside surface of the cylinder.  In another form, the sleeve is provided with a plurality of axially spaced, continuous annular grooves, which communicate at one or more places with the interior of the cylinder. The continuous grooves are blocked off at one or more places around the circumference of the cylinder to avoid leakage at the end-to-end discontinuity in a printing plate supported on the cylinder.           A relatively continuous media may be used around the exterior of the printing cylinder and about which the printing plate is wrapped and secured by vacuum.  In some cases, the porous media is a filter paper material, which may be of various thicknesses to accommodate printing plates of different thicknesses.  In other cases, the porous media may be a sintered metal coating, permanently bonded about the exterior of the cylinder.  In either case, the porous media serves to diffuse and render more uniform the appli-cation, of vacuum to the underside of the printing plate.

Abstract: ABSTRACT OF THE DISCLOSURE           A charged adsorbent is accommodated in a desorbing vessel and in an intermediate container which communicates with the desorbing vessel.  The charged adsorbent is desorbed in the desorbing vessel by contacting the same with a heat carrier, such as with hot sand, and a desorption gas which develops during the desorption of the charged adsorbent in the desorbing vessel is passed through the charged adsorbent accommodated in the interme-diate container to capture at least one component of the desorption gas in the charged adsorbent present in the intermediate container.      The purified desorption gas is withdrawn from the intermediate container, and the regenerated adsorbent is gradually discharged from the desorbing vessel and the supply of the adsorbent in the desorbing vessel is replenished by charged adsorbent from the inter-mediate container.  The desorption gas ?s cooled during the passage thereof through the charged adsorbent present in the intermediate container.  The magnitude of the temperature reduction of the de-sorption gas may be controlled by controlling the rate at which the desorption gas is discharged from the intermediate container, such as by resorting to the use of an adjustable vane.  The adsorbent in the intermediate container may be confined by gas-permeable walls through which the desorption gas enters and leaves the adsorbent present in the intermediate container.

Abstract: A B S T R A C T           In a telephone system having a two-conductor power supply to a subscriber's telephone, there is provided a circuit for supplying the conductors with d-c power using the principle of transforming a capacitance into an inductance between the conductors and a d-c power source.  The circuit comprises an electronic feed bridge consisting of a PNP transistor having its emitter connected to the positive side of the d-c power source via a variable resistor, and its collector connected to the first conductor, and an NPN transistor having its collector connected to the second conductor and its emitter connected via first and second series connected resistors to earth.  The bases of the two transistors are connected via bias resistors to their collector circuits and also to opposite terminals of a capacitor, the common point of the first and second resistors being connected to a tone generator, whereby various tones can be introduced to the subscriber's telephone.  The invention eliminates the need for large inductances and provides a means of compensating for the large variations in earth potential in different geographical areas to maintain interference from noise sources at a minimum.
