Title: Improvements in or relating to nuclear reactors
Inventor: BROWN GORDON
IPC: G21C15/02
Filed: 1964-05-26
Abstract: 1,100,721. Reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 14 May, 1965 [26 May, 1964], No. 21693/64. Heading G6C. In a pressurized gas cooled reactor, the graphite moderator core is provided with straight fuel channels which are inclined to the vertical to facilitate fuel handling. The fuel tubes are arranged in groups, and the axes of the tubes in each group converge so as to pass through a small zone above the group where the lateral separation of the axes is a minimum, after which they again diverge into the refuelling machine above the core. Thus, a single aperture in the pressure vessel provides access to a group of fuel channels from the servicing machine. The storage tubes in the servicing machine are mutually inclined so as to be aligned with the fuel tubes. To provide the mutual inclination of the fuel tubes, the latter are mounted in a twisted or screwed arrangement about the group vertical axis. The minimum separation zone of the axes acours within the pressure vessel wall, which also functions as the biological shield.

Title: Aircraft with autorotatable sustaining rotors
IPC: B64C27/02
Filed: 1937-08-06
Abstract: 485,967. Aircraft with rotary - wing systems. CIERVA AUTOGIRO CO., Ltd. Aug. 6, 1937, No. 21718. Convention date, Aug. 8, 1936. [Class 4] In an aircraft sustaining rotor having an even number of sustaining blades, both blades of an oppositely disposed pair being independently articulated on a single intermediate member about a pivotal axis or axes and the intermediate member being articulated to the hub member on a single pivotal axis, the axes are disposed so that the motion of the blades about their pivotal axes is wholly or principally a flapping motion, and that about the single axis wholly or principally a pitch-varying motion, a specified angular displacement about the pivotal axis or axes of the blades giving rise to a change of pitch angle, which, if any, is considerably less than that produced by an equal displacement about the second named axis. In one form, the rotor blades 13 are mounted through pivots 16, the axis f, f of which makes an acute angle as shown with the longitudinal blade axis a, a, on a member 17. The member 17 is mounted on a hub 18 by pivots 19, the axis of which makes an acute angle as shown with the longitudinal blade axis. This arrangement of axes tends to prevent flutter of the blades and also reduces individual flapping of the blades and permits the rotor to be disposed nearer the body 8. The hub 18 rotates in a member 20 mounted for tilting about a transverse axis 22 in a ring 23 mounted for tilting about a longitudinal axis in the pylon member 12. The rotor is tilted about the axes by lever and link mechanism to effect control of the aircraft. Rotation of the rotor is initiated by tilting tho rotor to engage a friction drive 34, 35. In a modification, the blades are pivoted to a member 39 mounted in journals 41. In a further modification the blades are pivoted as shown on a common pivot 42, Fig. 7, in a member 17<1> pivoted to an axis member about an axis disposed below the plane of the rotor.

Title: Improvements in or relating to electric filter arrangements
Inventor: HICKIN ERNEST MALCOLM
IPC: H01P1/213
Filed: 1960-06-22
Abstract: 905,842. Band-separating filters. GENERAL ELECTRIC CO. Ltd. June 8, 1961 [June 22, 1960], No. 21870/60. Class 40 (8). In a waveguide band-separating filter of the type comprising a 4-port circulator associated with two band-pass filters, the filters are designed to pass respectively the highest and the lowest of the signal bands transmitted through the device. The circulator shown, comprises two 3 db. branched directional couplers 8, 9 connected by parallel paths 14, 15 of equal physical length. The paths 14, 15 contain ferrite phase-shifters 16, 17 which produce non-reciprocal phase shifts of #/2 in opposite directions. In addition, the path 15 contains a variable phase changer 18 which produces a reciprocal phase change of approximately #/2. This arrangement results in an order of circulation 2, 5, 3, 4 between the four ports. Filters 6, 7 are designed to pass energy in two frequency channels of a signal containing a number (at least three) such channels applied at the port 2. Energy in the other channels is reflected by the filters and eventually appears at the port 4. Frequencies lying near the passbands of the filters tend to suffer more attenuation upon reflection than frequencies remote from the pass-bands. By arranging that the pass-bands of the filters 6, 7 correspond to the lowest and the highest of the channels comprised in the signal, the variation in attenuation of the reflected part of the signal is anulled. If the remaining channels are only two in number, they may be separated by a filter of the type described in Specification 899,191, connected to the port 4. If more than two channels remain, a cascade of filters according to the present invention may be used.
