Patent GB-2182464-A (GB)
Title: Vertical hydro-electric unit with floating rotor
Inventor: CHOY CHANG-TONG
IPC: H02K7/09
Filed: 1985-11-04
Abstract: The magnetic pull in an axial-field generator is utilized to support the rotating body of a vertical-shafted hydro-electric generating unit. The thrust bearing in the unit is eliminated and smooth starting and stopping are achieved. While the total excitation of the generator is kept constant in order to maintain the total e.m.f. generated unchanged, the magnetic flux densities in the generator's upper and lower airgaps are controlled by adjusting the currents in its two field windings. A feed-back system may be used to control automatically the output of generator exciter in response to the rotor's vertical displacement, generator armature current and output voltage.

Title: A method and apparatus for inhibiting thermal cycling
Inventor: TONG DONO KWOK WAI
IPC: G21C3/322
Filed: 1988-07-19
Abstract: Thermal cycling during mixing of fluid streams of different temperatures, for example liquid metal streams issuing from fuel sub-assemblies in a fast reactor, is reduced by sub-dividing each stream into a plurality of jets before the streams meet. A flow-diving means 36 may be of cruciform shape, or cruciform with a superimposed circle, to provide four jets and may have a tapered inlet to reduce drag. Dividing the stream reduces eddy size. Other shapes such as a rod, or oval or triangular section, are possible. The dividing means may be provided above the fuel sub-assembly rather than within in as shown. <IMAGE>

Patent GB-2214316-A (GB)
Title: Discriminating broadband and narrowband unipolar signals
Inventor: MORRISON SHAWN JOSEPH
IPC: G01R23/16
Filed: 1988-11-28
Abstract: For discrimination between a broadband unipolar signal (shown as a dotted line in Fig 4) having a component at a frequency ft within one or more of three predetermined frequency bands and a narrowband signal (shown as a solid line) within one of the frequency bands, a signal under test at 100, 110 Fig 5 is amplified 120 by a gain which is inversely proportional to the DC content of the signal under test to normalize the signal under test. The amplitude of the narrowband signal is then substantially larger (Fig 9) at the frequency than that of the broadband signal at ft. The normalized signal is bandpass filtered 132-136 to attenuate components outside of the predetermined frequency bands and the filtered signal is compared 170 to a reference signal 180. The signal under test is deemed to be a narrowband signal within one of the predetermined frequency bands if the filtered signal exceeds the reference signal. The method and apparatus are particularly useful for detecting test tones on optical fibers (Fig 1 not shown). <IMAGE>

Title: Combining digital video signals and photographic film material or the like
Inventor: RICHARDS JOHN WILLIAM
IPC: H04N7/01
Filed: 1990-11-15
Abstract: A system for combining a source digital video signal into 30 frame/s source material, such as film, employs a film scanner 304 to produce a digital video signal from a source film 300, a post-production system 318 for combining with that signal the source video signal (for example from a VTR 308, 314 or camera 310, 312), and recorders 326, 328 providing primary outputs for recording the combined signal on film 302, 330 in 24 frame/s and 30 frame/s format, respectively. The post-production system operates on 30 frame/s progressive scan format signals, so that frame/field conversion of the signals from the scanner and a 30 frame/s progressive scan format source (camera 308 or VTR 310) is not required. An alternative source video signal from a 60 frame/s 2:1 interlace format camera 312 or VTR 314 is converted to 30 frame/s progressive scan format by a converter 316. A number of secondary outputs 336, 338, 340, 342 are provided after conversion of the combined signal to 60 field/s 2:1 interlace scan format by a converter 332. Motion compensated interpolation is employed at stages of frame rate conversion, such as at the converter 322, but this is required only once between any of the sources and either of the primary outputs. <IMAGE>

Patent GB-2253185-A (GB)
Title: Reinforced alloy laminates
Inventor: MORETON ROGER
IPC: B32B15/14
Filed: 1991-03-01
Abstract: The stiffness of materials formed from aluminium alloy sheets laminated with layers of long aligned fibres embedded in a matrix of resin material is enhanced by reinforcing the aluminium alloy component with ceramic particles or whiskers. Use of stiff fibres such as carbon, aramid, alumina, silicon carbide or mixtures of these enables the stiffness of the fibre/resin component to be matched to that of the metal/ceramic component. This results in good fatigue crack growth resistance in the finished laminate, even for short crack lengths. In a preferred laminate, the metal/ceramic component is formed with a matrix of aluminium-lithium alloy. Such alloys are inherently stiffer than alloys without lithium, with the result that the increased stiffness obtained from ceramic reinforcement is enhanced still further.
