Abstract: 701,505. Centrifugal compressors; gas turbine plant. CENTRAX POWER UNITS, Ltd., and BARR, R. H. H. Sept. 20, 1950 [Sept 24, 1949], No. 24591/49. Classes 110 (1) and 110 (3) In a centrigugal compressor in which variation of mass flow is imposed by throttling means in the compressor or in plant receiving working fluid therefrom, the means for adjusting the throttling means is associated with means for adjusting the setting of adjustable intake guide vanes which impart whirl in the direction of rotation of the impeller, so that variation of the angle of incidence of the entering fluid relative to the impeller blades is reduced or obviated. The intake guide vanes 15 are pivoted about their longitudinal axes, which are parallel to the impeller axis. The vanes are arranged in a part of the intake where the flow is radially inward, but may instead be arranged in front of the impeller eye, with their arms disposed radially, in which case the vanes may be of twisted form. It may be arranged that the vanes impart no whirl at high mass flows. The vane pivots are provided with cranks 16 having pins 17 which engage radial slots 18 formed in a ring 19 which is rotatably supported on rollers 20. A pinion 21 which engages an internally toothed part of the ring 19 is rotated, for the purpose of adjusting the vanes 15, by a control lever or pedal which simultaneously operates the fuel valve of a combustion chamber fed by the compressor and also varies the area of the inlet nozzles of two turbines which receive working fluid from the combustion chamber. The turbines, which are of an inward-flow type similar in construction to a centrifugal compressor, are connected in series, the first one driving the compressor and the second one providing useful output. The compressor discharges to a volute by way of a vaneless diffuser having an outer radius at least 1¢ times the outer radius of the impeller. Specifications 587,509 and 701,503 are referred to.

Filed: 1964-06-16
Abstract: 1,093,812. Photo-electric direction finders. ELTRO G.m.b.H. June 16, 1964 [Sept. 17, 1963, No. 25000/64. Heading H4D. Apparatus for producing two images, in different wavelength ranges comprises two mirrors 1, 2 which reflect the incident radiation from a beam-receiving lens system (not shown) on to a prism surface 4 of a two-component prismatic deflection system 3, which surface in the illustrated example is transparent to the infra-red wavelength range and reflective to the visible wavelength range. The infra-red portion of the radiation passes through the surface 4 and a focusing system 5 to a modulation disc 6 to form an image point in the plane BI. The modulation disc 6 comprises alternate transparent slots and opaque webs, and rotates about its central axis and eccentrically about the optical axis. The polar co-ordinates of the image point in the plane BI are determined, with reference to the centre point of the plane, from the readings of a receiving element 7 situated behind the modulation disc 6. The visible portion of the radiation is reflected by the surface 4 and is again reflected by another surface of the system 3 before forming an image in the plane BII which is directly observed by means of an eyepiece 8. In a modification (Fig. 3, not shown), a further optical member (9) which acts as an interference layer transparent to one part of the infra-red wavelength range (e.g. # = 1.9 to 2.7Á) and reflective to the other part (e.g. # = 1.1 to 1À8Á), together with two oppositely connected receiving elements (10, 11) for the respective wavelength ranges, is disposed behind the modulation disc 6. Interference in the form of background radiation can be completely suppressed by automatic or manual adjustment of the signal transmission of the oppositely connected receiving elements (10, 11) and only that radiation lying within the first of the above-mentioned wavelength ranges used to determine the polar co-ordinates of an image point in the plane BI. The above apparatus may be used in combination with electronic computing and controlling apparatus to form an automatic guiding or homing sight for missiles. In this case, the visible image produced in the image plane BII is employed to sight the target so that the arrangement corresponds to a telescopic sight. The infrared portion of the radiation separated at the surface 4 and passing into the image plane BI is employed to determine the co-ordinates of a radiation-emitting missile reproduced as an image, relative to the optical line of sight through the target, so that remote control signals for the missile launched towards the target can be produced from the co-ordinate values corresponding to the distance of the missile from the launching site-target axis. In this way, the missile may be guided into and remote-controlled along the optical line of sight towards the target by means of a directly connected computing and steering unit.
