Title: Steam generating unit
IPC: F22G5/02
Filed: 1963-03-18
Abstract: 967,580. Regulating steam temperature in boilers. RILEY STOKER CORPORATION. March 18, 1963 [March 19, 1962], No. 10577/63. Heading F4A. In a steam generator comprising a vertical combustion chamber fired by burners in the lower part thereof and having a lateral gas outlet in the upper part of one wall to a pass locating a convection superheater, steam temperature is controlled by positioning the main stream of combustion gases within the chamber by means associated with the burners so that it flows upwardly against the gas outlet wall at low loads or against the opposite wall, from which platens of water tubes project, at high loads or is located at an intermediate position between the walls at intermediate loads, the temperature of the gases entering the convention pass thereby being controlled to maintain the superheat temperature at a preset value over the range of load. In the form shown the generator has an upright, tubelined combustion chamber 18 having a front wall 15 from which platens 75 of generating tubes project and a rear wall 16 provided at its upper part with a nose 33 forming the floor of a lateral pass 34 locating pendent superheater and reheater sections 62, 69 and leading to parallel down passes 37, 38 respectively locating primary superheater and reheater sections 61, 68, the gas flow through the down-passes being proportioned by dampers whereafter the gases combine for flow through an air heater 42 to a stack 44. At their lower portions the walls 15, 16 are provided with abutments 21, 23 on the lower surfaces of which openings are provided for burners 22, 24 respectively, the burners firing into a high temperature cell 19. The inclination of combustion air injection for the burners 22, 24 is respectively controlled by vanes 83, 85 and 88, 91, the vanes being set by actuators 96, 97 in response to variations of superheat and reheat temperature from a preset value, signals representative of these temperatures being received by a controller 101 from pick-offs 113, 115 respectively disposed in the superheater and reheater outlet headers. At low loads when the superheat temperature tends to fall below the desired value, the controller sets the vanes 88, 91 downwards and the vanes 83, 85 upwards causing the main stream of combustion gases to ascend against the rear wall 16 out of contact with the platens 75. The gases thus reach the convection superheater at a high temperature to maintain the steam temperature at the desired value. At high loads the vanes are set at opposite inclinations to cause the gases to flow through the platens 75, reducing their temperature and counteracting the tendency for steam temperature to be above the desired value at these loads. At intermediate loads the gas stream is positioned at the appropriate location between the front and rear wall. At all loads the gas proportioning dampers are also adjusted to give the correct relationship between superheat and reheat temperatures and at the highest loads spray attemperation may be used to reduce the superheat temperature.

[Classes 35 and 38 (iv)] A D.C. generator adapted to be driven by an internal combustion engine at variable speed is provided with, or is excited by an exciter provided with, two field windings of which one provides only a steady component of excitation independent of the load, and the other provides only a component proportional to the difference between a constant current and the load current, or a shunted part thereof, both components being variable with speed, whereby an approximately hyperbolic characteristic for constant-power output at different loads, is obtained at all speeds. The prime-mover 2 drives the generator 1 which has, or is excited by an intermediate exciter having two field coils, 1a fed by battery 5 through resistor 6, and 1b fed by a differential exciter 3 having two coils, 3a fed' by battery 5 and 3 b shunted across a resistor in series with the generator load. Exciter 3 is connected to the same shaft as generator 1, or, if an intermediate exciter running on the generator shaft is used, is run at constant speed. Resistance 6 enables the constant-excitation of coil 1a to be adjusted for different speeds when an intermediate exciter is not used ; or coil 1a may be fed by another exciter on the same shaft, if excited by battery 5. The excitation of exciter 3 passes through zero and is limited both ways by saturation. A shunt winding may be provided on the generator. The battery 5 may be replaced by a constant speed, shunt excited or battery excited, subexciter. A constant-voltage dynamo driven by the same shaft may be excited by a battery and by an opposing current from an exciter supplying coil 1a. The exciter 3 may also supply additional excitation to series motors running off the generator.

Filed: 1972-03-07
Abstract: 1414305 Cooling nuclear reactors UNITED KINGDOM ATOMIC ENERGY AUTHORITY 6 June 1973 [7 March 1972] 10661/72 Heading G6C In a nuclear reactor which has fuel cooled by an aqueous, main coolant which passes parallel to the fuel surface, emergency cooling is effected by supplying auxiliary coolant in jets which impinge upon the fuel surface, the positions of impingement being continuously varied to reduce the formation of hot spots. The main coolant may be either water or steam, or a two-phase mixture of both. In one embodiment (Fig. 1) main coolant from supply 6 passes via risers 4 to fuel clusters 3 each of which has a central sparge pipe 5 with nozzles 8 for delivering auxiliary coolant from a supply 7. In the event of failure of the main coolant supply, auxiliary cooling commences and the variation of the jet impingement positions is effected by creating a pulsating flow of water from a supply 10 and feeding it to the risers 4. The flow may comprise hot water in which ease a pressure pulse is created in each cluster 3 as the water flashes to steam; or, the flow may comprise cold water in which case a pressure pulse is created in each cluster 3 as the water condenses steam in the cluster. An interrupter pump 11 causes the flow to pulsate. In a second embodiment (Fig. 2) the sparge pipe 20 comprises inner and outer parts 23, 24 the former of which is rotatable and houses impingement vanes 25 whereby incoming auxiliary coolant causes its rotation. Both tubes 23, 24 have helical slots in their surfaces so that through apertures are created where the slots coincide.

Abstract: 1,033,944. Copy-turning. EDOUARD DUBIED ET CIE S.A. March 19, 1963 [March 29, 1962], No. 10891/63. Headings B3B and B3T. [Also in Division B8] A device for supply and removing workpieces from a lathe comprises a vertical magazine H, means 14 for positively ejecting the lowest workpiece into an open carrier 116 which is then moved in a straight line to position the work between the lathe centres, and an inclined ramp J for receiving machined workpieces. The magazine H has front guides adjustable transversely on laterally adjustable supports 3 to permit workpieces of varying diameters and lengths to be accommodated. In operation, the work spindle is stopped when machining is complete and a slide K is advanced by hydraulic means to receive the workpiece as it is released by opening of the chuck and retraction of the tail stock. When the slide is retracted, a flap at its rear is cammed open and the workpiece rolls into a collection channel M. A slide D carrying a loading arm B is raised by hydraulic means E. In its upper position, the slide abuts lever means to rotate the ejection arms 14, Fig. 6 (not shown), thus moving the lower workpiece 1 over a ramp 9 into the pivoted cradle 116 of the arm B. The arm B is lowered, the workpiece is gripped in the machine and the arm raised, the cradle 116 snapping over the workpiece in its upward movement. If manual operation is required, the hydraulic power is cut off and thereby a pawl is released which locks the slide D in its upper position. Finished pieces can be removed in a trolley. Cushioning pads prevent noise from the unloading operation and a guard protects the operator from chips and lubricant. A lamp warns the operator when no workpieces are left.
