A pump for supplying two circuits at different pressures comprises two rotary cylinder block units 1, 2 with their outputs connected to the respective circuits and their inputs connected to a common feed pump formed by gears 13, 14 synchronizing the cylinder block drive-shafts 11, 12, the pistons 5 of both block units engaging a common swash-plate 9. A part-cylindrical cradle supports a complementary bearing face of the swash-plate 9, hydraulic balancing chambers 25 in the swash-plate being connected to the respective output circuits. Transverse grooves 17 in the part-cylindrical face of the swash-plate co-operate with ports in the cradle face connected to the feed pump inlet and outlet, such that movement of the swash-plate to decrease the pump output short-circuits the feed pump, Fig.4 (not shown). The feed pump output is greater than the maximum intake requirements of the two cylinder block units, the excess output being by-passed by a relief valve, Figs. 7 and 9 (not shown). The swash-plate inclination is controlled by a hydraulic jack subjected to the output circuit pressure, the jack operating against the bias of a spring assembly, Fig. 3 (not shown). A spring- loaded plunger 37 biases the swash-plate on to its cradle. To provide smooth operation, the tilt axis of the swash-plate is off-set from the plane containing the cylinder block axes, and one cylinder block is mounted on its drive-shaft splines so as to be out of phase with respect to the other, Fig. 1 (not shown).

Abstract: 1302028 Monitoring reactors UNITED KINGDOM ATOMIC ENERGY AUTHORITY 24 March 1970 [27 March 1969] 16247/69 Heading G6C [Also in Division H4] To determine the position of a blockage in a gas-filled pipe or of a hole in the pipe wall, a varying frequency acoustic signal is generated in one end of the pipe and the average frequency spacing of the natural resonances of the gas column in the pipe is evaluated. In the Fig. 1 embodiment the pipe 11 forms part of a burst fuel can detecting system which samples gas in nuclear reactor vessel 14. Outside the vessel 14 the pipe 11 has a branch 11b joined to a conventional electrostatic precipitator device 15. Variable frequency oscillator 22 drives loudspeaker 19 on a pipe extension 18 connected by a flanged joint 17 to a second branch 11c and resonances are detected by microphone 20a feeding a frequency response indicator 21 which plots sound level against oscillator frequency. A second microphone, 20b, may provide a reference signal for use with a coherent demodulator in indicator 21, to discriminate against extraneous noise. Digital computer 23 may be used to calculate the distance from microphone 20a to an impedance discontinuity (hole or blockage), which distance is related to the mean frequency spacing of the resonances. Computer 23 or an ordinary spectrum analyser may alternatively be used to carry out an harmonic analysis of the frequency response of the pipe to indicate distances to one or more impedance discontinuities. A tape recorder (24, Fig. 3, not shown) may replace oscillator 22 and indicator 21, a pre-recorded frequency sweep being used to drive loud-speaker 19 and the microphone signals being recorded for later analysis.

Abstract: 1315945 Electron microscopes CAMBRIDGE SCIENTIFIC INSTRUMENTS Ltd 10 Feb 1972 [12 Feb 1971] 4604/71 Heading H1D [Also in Division G1] A scanning electron beam micro-analyser has provision for switching back and forth continuously between a first mode of operation in which the beam scans back and forth over a region of a specimen surface, and a second mode in which the beam rocks angularly about a fixed point on the specimen surface, Fig. 2, to cyclicly vary the angle of incidence of the beam. As shown, the device includes focusing coils L1, L2, and L3, and two pairs each of upper and lower scanning coils UC and LC (only one pair of each shown). The first image of the source is formed at point P2 in both modes, the lower deflection coil LC being switched on and off, with simultaneous change of the deflection current fed to the coils UC, to move the second image of the electron source from the specimen surface, corresponding to the rocking mode shown in Fig. 2, to the aperture of the lens L3 (Fig. 1 not shown), to provide the area scanning mode. In an alternative arrangement, Fig. 3, switching to the area scanning mode is achieved merely by an increase in current to the lens L3, raising the second image point above the specimen surface as shown, the resultant partial defocusing being accepted. Either the secondary or the backscattered electrons, the X-rays produced, or the specimen current, is detected and amplitude modulates the beam of a synchronously scanned cathode ray tube. Reference is made to the use of more than one detector, e.g. for back-scattered electrons and for X-rays respectively, and to the use of a conical or spiral, rather than rectangular, scan in the rocking mode. A circuit is described (Fig. 4, not shown), for switching the deflection current or the current to lens L3, with simultaneous change of gain of an amplifier in the detector circuit, and transfer of the detector output from a first to a second cathode ray tube.
