Abstract: A B S T R A C T         This relates to a method of operating a recovery boiler at maximum reduction efficiency.  The boiler has a plurality of air inputs including a primary air input closest to the bed of the boiler, a fuel input, a smelt output, and an exhaust output.  The method comprises measuring the amount of sulphur dioxide at the exhaust output, and varying the amount of air entering the boiler through the primary air input until the minimum amount of sulphur dioxide is measured at the exhaust output.  In a preferred form the method may be utilized in conjunction with the steps of detecting the amount of carbon monoxide at the exhaust output and changing the total amount of air entering the boiler until the amount of carbon monoxide detected equals a target value for best combustion efficiency.

Abstract: ABSTRACT     A phase locked loop circuit having a pulse swallowing gate for receiving a pulse train from a controllable oscillator, wherein a number of pulses are removed by the gate in dependence upon a control signal generated by a programmable frequency divider receiving a clock signal.  The programmable frequency divider also generates a reference signal which is fed to a phase comparator, and which generates a second control signal dependent upon the phase difference between the reference signal and the pulse train which has been passed through the pulse shallowing gate.  The second control signal may then be fed to the controllable oscillator to control the frequency of the pulse train.  Such control is useful for instance in frequency synthesizers.

Abstract: ABSTRACT OF THE DISCLOSURE          A method of joining elements by explosion-welding comprising the steps of placing a charge within a mass of inert material eccentrically thereof, whereby to provide a wall of inert material of lesser thickness adjacent one outer portion of the charge as compared to adjacent the remaining outer portions of the charge; and placing the charge and mass of inert material in the vicinity of where the joint of the elements is to be made, in readiness for effectively explosion-welding the joint, including orientating the mass of inert material relative thereto such that the wall of lesser thickness faces where the joint of the elements is to be made.  The invention provides to considerably limit the quantity of charge required, especially by giving it cylindrical shape and enclosing it in an inert medium serving as blasting medium and medium for transmitting shock waves.  This particular shape eliminates the dependence on detonation speed and high-precision explosive charges can be selected, which can be detonated at small cross-sections.  The cylindrical shape of the splicing material also increases the tolerance limits for irregularity of the metal elements.  In a further aspect there is provided a charge device for use in explosion-welding elements together comprising; a mass of inert material having an outer peripheral surface and an explosive charge in the material and surrounded thereby, the charge being positioned eccentrically of the mass whereby to provide a thin-ner wall of inert material on one side thereof to that of an opposite side thereof.  The invention also permits splicing from both sides of the elements to be joined, thus eliminating the need for supports to prevent deformation.

Abstract: ABSTRACT       A locking pivot connection for removable ejector latches for an electrical connector comprises a pair of opposed pivot pins located on each end of the connector.  Each pivot pin comprisesg two opposite flat sides and two opposite curved sides, the thickness of the pivot pin measured between the flat sides being less than the thickness of the pivot pin measured between the curved sides.  A pair of circular pivot cups are located on opposite sides of the ejector latch, and a pair of entry slots on opposite sides of the ejector latch join the outer edge of the ejector latch with the pivot cups.  The entry slots have a width slightly larger than the thickness of the pivot pin measured between the flat sides or the pivot pin to allow the ejector latch to be slid onto the pivot pins in a direction generally parallel to the plane of the flat sides of the pivot pins.  The ejector latch may be locked onto the pivot pins by rotating the latch to skew the entry slots relative to the flat sides.

Abstract: INFRARED SENSOR FOR THE CONTROL OF PLASMA-JET SPRAY COATING PROCESSES                  Abstract of the Disclosure A multi-purpose optical sensor operates in the medium-to-far infrared wavelength spectral region to sense the surface temperature of plasma-jet spray coating materials.  The plasma itself emits little or no radiation in the region and, accordingly, the output signal from the sensor is used to adjust electrical input and other variables associated with the plasma spray torch to insure that particles arriving at the substrate surface to be coated are, in fact, in a molten state.  The sensor employs infrared interference filters and, additionally, the sensor may be used to monitor not only coating temperature but also plasma beam divergence and particle seeding density to provide other control functions.
