Patent DE-3365424-D1 (DE)
Title: Active impedance line feed circuit
Inventor: ROSEMBAUM STANLEY DANIEL
IPC: H04Q3/00
Filed: 1983-05-11
Granted: 1986-09-25
Abstract: A line circuit includes tip and ring voltage amplifiers (20, 40) each having an output resistively connected via tip and ring feed resistors (12, 13) to tip and ring leads (2, 3) in a telephone line. The tip and ring feed resistors have closely matched ohmic values, and are part of a resistance network (10) which also includes first and second voltage dividers (14, 15). The first voltage divider (14) is connected in series between the output of the tip voltage amplifier and an end of the ring feed resistor remote from the output of the ring voltage (15) amplifier, and includes a first voltage tap (6). The second voltage divider is connected in series between the output of the ring voltage amplifier and an end of the tip feed resistor remote from the output of the tip voltage amplifier, and includes a second voltage tap (7). A control circuit (60) includes a differential input connected across the first and second voltage taps, in operation the control circuit causes the tip and ring voltage amplifiers to provide energizing direct current for the telephone line. Tip and ring feedback networks (16, 17, 18, 19), connected across the respectively tip and ring feed resistors, provide feedback signals to the tip and ring voltage amplifiers such that in operation common mode rejection of longitudinally induced a.c. signals on the telephone line is enhanced.

Title: A joint on packing containers and a method for the manufacture of the same
Inventor: SJOSTRAND UNO
IPC: B29C65/02
Filed: 1983-12-05
Granted: 1989-06-01
Abstract: Joints in packing containers of heat-sealable gas-tight laminate are sensitive to deformation, since this often results in a deterioration of the gas-tightness. This is due to the accumulation of melted thermoplastics which is produced during the heat-sealing. The said weaknesses are eliminated in that the sealing zone (6) of the joint is given a limited width and is placed at a distance from the edge (5) of the laminate. A method and an arrangement for realizing this comprises a heating zone whose width is limited in relation to the width of the sealing jaws which are used for the sealing together of the material layers.

Abstract: NOx reduction in a combustion product flue gas stream is greatly improved by the efficient mixing of the reducing agent, e.g., NH3 or an NH3 precursor, with the stream in the absence of a catalyst, such as CaO or CaCO3, that promotes undesirable combination of NH3 and O2 to form additional NOx. By employing a high-temperature cyclone separator of the like and by injecting the reducing agent into the stream within such hot cyclone at a location where there is a strong vortex region, extremely efficient mixing of the NOx reducing agent and the combustion product flue gas is promoted after particulates which are harmful to the reaction that promotes NH3 and NOx reduction have been separated from the flue gases. A refractory-lined cyclone separator may be employed, and a plurality of injectors used which discharge liquid or gas into the strong vortex region.
