摘要： A patient monitoring/signal processing module with increased electrical isolation is disclosed. The combination of an inner isolation piece and an isolation film provide signal isolation and electrical over-voltage protection between a lower, isolated portion of the unit defined by a lower housing and the isolation piece and an upper, non-isolated portion of the unit, defined by an upper housing and the isolation piece, increasing the module's ability to survive an over-voltage condition without damage to itself or to the patient to whom it is coupled. The combination of the isolation film and the isolation piece results in a much thinner module than would otherwise have been necessary to achieve the same levels of signal and electrical isolation.

摘要： A heat exchanger for cooling hot reaction gas with a coolant. It rests on a gas-supply compartment (4) and has gas-conveying pipes (9) inside a jacket (1). It is separated from the gas-supply compartment by a tube sheet (6) that accommodates the gas-conveying pipes (9). The pipes extend loosely through the tube sheet, leaving annular gaps (10) and are connected tightly to the tube sheet on the side where the gas enters. The heat exchanger has at least one line (12) for supplying coolant to the side of the tube sheet that faces away from where the gas enters. The diameter of the tube sheet is shorter than that of the jacket. The tube sheet is connected to the lower edge of the jacket by way of an upward-tapering cone (7). The tube sheet is provided with cooling channels (15) that are open at least at one end and communicate with the lines that supply the coolant.

摘要： A tube bundle heat exchanger having an additional tube bottom with insertion tubes arranged in the inlet chamber upon the inlet side of the hot gases for the tubes located between the tube bottoms of the tube bundle. The additional tube bottom is arranged in such a way that both tube bottoms in the inlet chamber define another inlet chamber for colder, slag-free gases, which inlet chamber is accessible through an inlet in the shell of the tube bundle heat exchanger. The insertion tubes project far into, but not to the end of, the tubes of the tube bundle. The insertion tubes, with the outer tubes, form relatively narrow annular spaces suitable for generating high discharge speed. Four spiral formed strips respectively located in the annular spaces impart a twist to the gas flow discharging from the annular spaces to assure that gas discharging between the insertion tubes and the tubes of the tube bundle remain in flowing contact along the inner walls of the tubes. Slag-containing gas coming from a coal gasificatin reactor flows through an inlet into the inlet chamber of the tube bundle heat exchanger and is cooled off in three regions during flowing through the tube bundle heat exchanger whereby temperatures of the cooling-off gas are maintained in such a manner that slag is precluded from depositing upon the heat transfer surfaces while the gas is cooling off.

摘要： A device for cooling a reactor positioned in a vessel. The vessel comprises a water space and a steam space. Cooling pipes that convey evaporating water extend through the reactor. The pipes communicate outside the reactor with the water space at the intake end and with the steam space at the outflow end. The object is to prevent local excess cooling that would interfere with the reaction. A fresh-water preheating section is positioned inside the steam space. The preheating section communicates with an inflow outside the vessel and with an outflow inside the steam space. The preheating section also has open pipes extending through it from top to bottom into the steam space.

摘要： A bundled-tube heat exchanger of the vertical arrangement type has a gas inlet chamber and a gas outlet chamber. These gas chambers are connected by gas transfer tubes. The gas transfer tubes are surrounded by cooling medium tubes within a housing chamber. Each of the cooling medium tubes opens out into a respective connecting chamber that is formed between the casing chamber, the gas inlet chamber, and the gas outlet chamber. A gas transfer tube that is open to the casing chamber connects the casing chamber to a connecting chamber.

摘要： A heat exchanger for cooling cracked gas has a nest of heat-exchange tubes (1) that the gas flows through and that are secured at the ends in bases (2 and 3) and surrounded by a jacket (4) that demarcates in conjunction with the bases a chamber occupied by evaporating water. Each heat-exchange tube has two sections (10 and 11) that differ in diameter and communicate through a cone (12). The section (11) with the longest diameter is at the emerging-gas end of the heat-exchange tube.

摘要： Device for cooling gases deriving from ammonia synthesis. The device consists of pipes accommodated in an interior space. The space is subjected to a heat-absorption medium and surrounded by a cylindrical mantle. The pipes are secured in a pipe floor and communicate with a gas-intake chamber and a gas-outlet chamber. When an ammonia-production plant has several reactors, a single gas-cooling device has up to now been associated with each. The new device is intended to decrease the engineering expenses involved in cooling the gases in such plants. A gas-intake chamber and a gas-outlet chamber is positioned at each of the two opposite ends of the jacket. Straight pipes are associated with each chamber. The pipes are adjacent and the gas flows through them in opposite directions.
