Title: Method for producing gaseous oxygen and a cryogenic plant in which said method can be carried out.
IPC: F25J3/04
Filed: 1982-05-24
Abstract: A method for producing gaseous oxygen, preferably at pressures in excess of 35 bars A, by the fractional distillation of air using a conventional double column having a high pressure column (6) and a low pressure column (11). Liquid oxygen is withdrawn from the bottom of the low pressure column (11) and is pressurized to lust above the desired product pressure by pump (13). The liquid oxygen is then vapourized in heat exchanger (15) using nitrogen from the top of the high pressure column (6). The nitrogen is compressed in compressor (28) to 41 bars A and in compressors (32 and 34) to 80 bars A. The stream (35) is sub-cooled in heat exchanger 15 and, after expansion at valve (36), the liquid nitrogen is returned to the high pressure column as reflux. The stream (31) is cooled in heat exchanger (15) and is expanded in an expander (40). The gas leaving the expander (40) is used to cool the stream (35) in heat exchanger (15) and is subsequently recycled to the inlet of compressor 28.

Title: Boiler sootblowing optimization.
IPC: F23J3/00
Filed: 1984-07-11
Abstract: A method of identifying a parameter of a model for a rate of loss of boiler efficiency due to a soot-blowing operation, in a boiler or other convection heat transfer device having a plurality of heat traps, comprising measuring a time since a last sootblowing operation in the heat trap in question, measuring an overall boiler efficiency at the beginning of soot-blowing for the heat trap in question, measuring a change in efficiency due to the sootblowing operation and calculating the parameter using an equation. According to the equation, the ratio of efficiency change over overall boiler efficiency equals the time factor since the last sootblowing operation times the parameter minus a summation of factors for each of the other heat traps and their associated sootblowing operations. A method is also disclosed for enhancing a sootblowing operation wherein, with a plurality of heat traps, sootblowing is performed in an upstream heat trap in preferance to a downstream heat trap, when both heat traps are near a fouled condition which would require sootblowing. This prevents premature fouling of a downstream heat trap which has recently been cleaned by soot blown off an upstream heat trap.

Title: Floor position sensing apparatus and method.
IPC: G05D1/02
Filed: 1986-02-04
Abstract: Apparatus and method by which an unmanned, trackless, work-producing vehicle is able to follow a path defined by a passive metallic marker or markers or by which the vehicle can receive information represented by passive metallic markers. Metallic markers can be secured or applied to appropriate surfaces, such as the floor surface of a vehicle work area, and do not need to be connected to any signal-generating device. An alternating magnetic field is generated by a master coil carried on the vehicle. The alternating magnetic field produces a secondary field around the metallic marker. Both magnetic fields produce voltages in a plurality of spaced secondary coils located on the vehicle. The existence of the metallic marker as a bench mark is identified by comparing the phases of voltages produced by the primary and secondary fields in each separate secondary coil. This excludes any stray fields, which may be extraneously produced in the secondary coils. The location of the marker with respect to the vehicle is determined by comparing the magnitude of the voltages produced in the plurality of secondary coils.
