Title: Improvements in or relating to centrifugal compressors
IPC: F04D17/12
Filed: 1950-10-03
Abstract: 690,951. Centrifugal compressors. CARRIER ENGINEERING CO., Ltd. Oct. 3, 1950 [April 26, 1950], No. 24185/50. Class 110(i) A centrifugal compressor comprises a penultimate stage comprising an impeller and a bladeless diffuser surrounding the impeller, and a final stage comprising an impeller and a volute, the impellers being of approximately the same diameter and the penultimate -stage producing 54 to 60 per cent of the total work done by the two stages. Guide vanes 9 impart whirl to the gas entering the first impeller 5 of a two-stage compressor. A bladeless diffuser 6 and a return channel 7 containing whirl-imparting vanes 10 lead the gas to the second impeller 13, from which it is discharged to a single- or multioutlet volute 15. 54 to 57 per cent of the total work of compression is done by the impeller 5, in which the area of flow decreases as the radius increases, so as to reduce the gas velocity by about 10 to 15 per cent. The angle between the blades 23 and the tangential direction varies from 40 degreesŒ5 degrees at the impeller periphery to 26 degrees Œ 3 degrees and 30 degreesŒ3 degrees at the edge 51 and edge 52 respectively, Preferably, the variation of blade angle is such as to maintain a constant angle of attack along the inlet edge of the blade. Over at least the last half of the length of the passageways of the impeller 13, the flow area increases with the radius so as to reduce the gas velocity by about 15 to 20 per cent, the velocity head at outlet being less than 2/3 of the corresponding head in the first stage. The angle between the blades and the tangential direction decreases with increasing radius over about the last half of the passageway length, with a value at the impeller periphery of 18 degrees Œ 3 degrees. Impeller 13 is about equal to impeller 5 in diameter, but the axial distance between the back plate and cover plate at the eye and periphery is 80Œ5 per cent and 75 to 100 per cent respectively of the corresponding measurement of impeller 5. The volute throat 36 is made greater in width than the impeller tip so as to reduce the gas velocity by 5 to 15 per cent. The sides 53 have angles of less than 30 degrees, giving a further reduction of 15 to 20 per cent to the tongue of the volute. In the volute proper and in the discharge pipe further reductions of 27 and 38 per cent respectively may be obtained.

Title: Improvements in or relating to wireless telegraphy and telephony
IPC: H04B7/06
Filed: 1926-09-30
Abstract: 259,226. Telefunken Ges. f³r Drahtlose Telegraphie. Oct. 1, 1925, [Convention date]. Transmitting Systems; aerials; fading, preventing and limiting.-In order to prevent fading and the occurrence of dead zones, particularly in shortwave signalling, transmission is effected by superposing two circularly-polarized waves whose mutual phase-relationship is periodically changed. Two aerial systems 1 - - 4, each similar to that shown in Fig. 1, may be so energized as to radiate the one a right-handed and the other a left-handed circularlypolarized field. This is ensured by effective a phase-displacement of 90 and 270 degrees in the respective feed lines. If, in addition, the oscillations in one aerial are periodically interrupted at a lower frequency, by means of an interposed and separately-excited thermionic valve, the resultant field from the entire system will be linearlypolarized, but the plane of polarization will constantly vary in direction. Fig. 4 shows an arrangement for securing this result without necessitating the use of any phase-displacing means in the feed lines. Instead, the aerial arm 1, 2 is displaced by a distance of a quarter wavelength from the arms 3, 4, the arms 1', 2<1> and 3<1>, 4<1> being similarly arranged. The coupling at 6 is in the reverse sense to that at 6<1>. An interrupter valve 11, energized from a separate source 12, is interposed in a common portion of the feed lines 9<1>, 10<1>. The antenna wires 3. 4 are normally arranged horizontally, as shown. The corresponding wires 1, 2 may be inclined in order to radiate the energy at any desired angle to the horizontal.

Abstract: 997,773. Aerials. HUGHES AIRCRAFT CO. June 21, 1963 [Aug. 22, 1962], No. 24792/63. Heading H4A. [Also in Division H1] An aerial array is formed of two groups of slots 42, 48, Fig. 2, in a broad wall 25 of a rectangular waveguide 24 and the groups radiate in respectively different frequencybands by reason of the groups of slots coupling to two differ ent modes propagated through the waveguide. In one embodiment the TE 10  and TE 30  modes are propagated through the waveguide 24 and for the TE 3o  mode the waveguide may be thought of as three adjacent " waveguides " 24a-24c each supporting the TE 10  mode at the higher frequency and each having common " virtual walls " 52, 54. A group of shunt slots 42 resonant at the higher frequency are disposed along the waveguide at odd multiples of the higher frequency quarter wavelength and spaced on alternate sides of the centre lines 36, 38, 40 of the " waveguides " 24a- 24c, so that the slots radiate in phase. A second group of slots 48 is coupled to the TE 10  mode by posts 50, Fig. 5, the slots 48 being located along the centre line of the waveguide and the posts 50 being positioned in the planes of the " virtual walls " 52, 54, to avoid coupling to the TE 30  mode. The TE 3o  mode is coupled from a waveguide 72 into one end of the waveguide 24 by slots 66, Fig. 4, resonant at the higher frequency. A slot 78 resonant at the lower frequency and situated on the centre line 38 of the waveguide 24 serves, together with a probe 76 positioned in the plane 54 of the " virtual wall " or mode of the TE 3o  mode, to propagate the TE 10  mode. The other end of the waveguide 24 may be closed by a plate or a matched load and in other embodiments other arrangements of slots are described with reference to Figs. 6-10 (not shown), some embodying dielectric loaded slots.
