    • An electrical machine comprises a four-pole stator (2) provided with a field winding (10) and an armature winding (11), each of the windings (10, 11) being split into two coils (22, 23 or 24, 25) closely coupled and wound so that diametrically opposite portions of both coils are disposed within diametrically opposite stator slots. A two-pole rotor (not shown) without windings is rotatable within the stator (2), and a circuit is provided for energising the armature coils (24 and 25) when direct current is supplied to terminals (26 and 27) of the circuit. Switches (28 and 29) in series with the coils (24 and 25) are switched alternately to effect alternate energisation of the coils (24 and 25) so as to generate, as a result of the opposite winding of the coils, magnetomotive forces in opposite directions. Since each of the closely coupled coils (24 and 25) generates a magnetomotive force in a respective direction, each coil needs to be energised with current in only one direction so that a relatively simple excitation circuit can be used.

    • A thermal compressor (10) comprises two adsorbent beds (11, 12) each with an associated thermal management system (14). The thermal management systems (14) are identical and consist of a circulating supply of a control fluid which passes through the adsorbent bed, a pump (15), a heat exchanger (16) and an inert bed (17, 18). Heat removed from the adsorbent beds (11, 12) by the control fluid is supplied to the inert beds (17, 18) and is stored to be subsequently regenerated to heat the adsorbent beds (11, 12) in a later half of the operating cycle of the thermal compressor (10). The thermal compressor (10) is energy efficient by virtue of the heat recycling which is performed.

    • Tandem mass spectrometry apparatus comprises a serial arrangement of an ion source (10), a first time-of-flight means (20, 80), a collision cell (40) to generate fragment ions and a second time-of-flight analyser (50). The second time-of-flight analyser comprises an ion mirror (51, 52) which is arranged to produce a quadratic field along or at an angle to the optical axis of the apparatus. The first time-of-flight analyser may comprise a sequential S configuration of toroidal or cylindrical electrostatic analysers (70) or may comprise two electrostatic lenses (80, 96) to either side of an ion mirror or may comprise an electrostatic lens (80). The first time-of-flight analysers thus comprise electrostatic field means for providing spatial focusing of ions in all three dimensions at or near the entrance to the ion mirror of the second time-of-flight analyser (50). The spatial focusing, concomitant with time focusing, is the essential requirement for the quadratic field mirror to give high resolution.
    • 串联质谱装置包括离子源(10),第一飞行时间装置(20,80),产生碎片离子的碰撞池(40)和第二飞行时间分析仪( 50)。 第二飞行时间分析仪包括离子镜(51,52),该离子镜被设置成沿着设备的光轴或与其光轴成角度地产生二次场。 第一飞行时间分析器可以包括环形或圆柱形静电分析器(70)的顺序S配置,或者可以包括离子镜的任一侧的两个静电透镜(80,96),或者可以包括静电透镜(80) 。 因此,第一飞行时间分析器包括静电场装置,用于在第二飞行时间分析仪(50)的离子反射镜的入口处或附近提供所有三维空间中的离子的空间聚焦。 随着时间的推移,空间聚焦是二次场立体镜提供高分辨率的基本要求。
