摘要： A drive configuration for a skid steered vehicle comprises a pair of electric motors (1a, 1 b) for propulsion of the vehicle, one each coupled to drive a respective track (5a, 5b) on a respective side of the vehicle, and one or more electric steer motors (7a, 7b) coupled through a differential gear mechanism (6) to impose a speed difference between the tracks. An associated control system (20, 24, 25, 26) controls the current to each motor so that substantial contributions to the differential torque to turn the vehicle are made both by the steer motors and by the propulsion motors, in variable proportions preferably as a function of the vehicle speed.

摘要： A self-energising brake assembly, particularly for braking a drive shaft of a heavy tracked vehicle such as a tank, has a pair of discs (26, 27) carrying friction pads (12) borne to rotate with the shaft. These friction discs are located to either side of a central non-rotating water-cooled disc assembly (9). A control brake disc (13) is also borne to rotate with the shaft but capable of turning relative to the same via a ball screw assembly (32). To apply the brake the control disc (13) is retarded relative to the shaft by means of an associated calliper (not shown), which causes relative axial movement between the inner and outer rings (35, 36) of the ball screw. This movement drives the friction disc (27) axially along the shaft, on a ball spline (29-31) , towards the friction disc (26), thus clamping the non-rotating disc (9) between the two friction discs and braking the shaft.

摘要： A low-noise axial flow impeller has a multi-cellular form of construction comprising a multiplicity of individual axial flow channels (2) disposed in a circumferential and radial array with respect to the axis of rotation. This increases the “blade passing frequency” as compared to a conventional impeller and since higher frequencies have lower energy for a given flow output the total amplitude of the noise generated can be reduced. For high total flow area coupled with low structural weight the channels (2) are arranged in tessellating rings of equal numbers of channels, with channel cross-sections based on hexagons (or truncated hexagons in the case of the channels in the innermost and outermost rings). In another embodiment each channel also extends from a respective channel inlet to a respective channel outlet which is offset from the respective inlet in the radial direction of the impeller, and involves an increase in the internal dimension of the respective channel in the direction radial to the axis of rotation, thus assisting deceleration and compression of the air or other medium being conveyed as it flows through the channels.
摘要翻译：低噪音轴流叶轮具有多孔结构，其包括相对于旋转轴线以周向和径向排列的多个独立的轴流通道。这增加了与传统叶轮相比的“叶片通过频率”，并且由于较高频率对于给定的流量输出具有较低的能量，所以可以减少产生的噪声的总幅度。对于高总流量面积与低结构重量，通道布置在相同数量通道的镶嵌环中，通道横截面基于六边形（或在最内圈和最外圈的通道的情况下为截头六边形）。在另一个实施例中，每个通道还从相应的通道入口延伸到相应的通道出口，该通道出口在叶轮的径向方向上从相应的入口偏移，并且涉及相应通道的内部尺寸在径向向内延伸的方向上的增加从而有助于当空气或其它介质流经通道时被输送的减压和压缩。

摘要： An electrothermal heater mat for anti-icing or de-icing of a helicopter rotor blade or other aerodynamic surface comprises a substrate, such as a flexible polyimide sheet 6, bearing tracks 7A-7E of a material of selected electrical resistivity, these tracks being formed by printing onto the substrate with a thermosetting ink loaded with electrically conductive (e.g. carbon) particles. Electrical bus bars/terminals 8/9A-9E for the supply of electrical energy to the resistive tracks may also be printed, using an ink loaded with particles of higher conductivity material such as copper or silver.

摘要： Fascines for filling ditches or smoothing other discontinuities in or on the ground to facilitate the passage of vehicles across the discontinuity are composed of inflatable members (1) of the kind comprising an inflatable chamber (4) configured to define a hollow tube when inflated. These tubes, or at least selected lengths thereof, are reinforced internally against deformation under applied load, by means of additional inflatable chamber (5) which may themselves be of hollow or “solid” form, or by means of flexible tension members tied across the interior of the tube to resist expansion of the tube cross-section in the plane perpendicular to the load.

摘要： A tip device to act as an outboard continuation of an aircraft wing or other aerodynamic lifting surface has a downward cant angle, a leading edge swept back in relation to the leading edge of the inboard lifting surface, and a chord reducing in the outboard direction of the device. A favourable balance between induced drag reduction and increased wing root bending moment can thereby be achieved. Preferably the device also has an upwardly canted portion at its root end so that the downward cant commences from a relatively elevated spanwise location, thereby alleviating any ground clearance problems.

摘要： This invention relates to a pumping system. The design of the system is such that bi-directional operation can be achieved using a significantly smaller and hence lighter unit than those currently available. It uses the direction of rotation of the drive shaft to control the opening and closure of the by-pass means for controllably returning the fluid to the first reservoir.

摘要： A respirator assemby e.g. for NBC protection is formed from two separate sub-assemblies (1 and 2). The first sub-assembly (1) comprises a flexible hood (3) (or other suitable headgear), a rigid mounting ring (4) and a peripheral face seal (6). The second sub-assembly (2) comprises a face plate (7) with lens (8), oronasal mask (10) and inlet and outlet valves (15, 16), and is demountably attachable to the ring (4). The first sub-assembly can be worn on its own with the user breathing ambient air through the open front, the second sub-assembly being added if and when a hazard is encountered. The positioning of the face seal (6) in the first sub-assembly means that a comfortable and reliable fit can be ensured when that sub-assembly is donned prior to a mission, but the user is relieved of the physiological burden of wearing the complete respirator unless and until protection is required.

摘要： A micro power unit comprises a Rankine cycle circuit powered by combustion of hydrocarbon fuel from a tank (2). Combustion takes place on a combustion catalyst (6) in a chamber (5). The fluid circuit includes a boiler (10), turbine (11), condenser (12) and feed pump (13). The feed pump impeller (13A) is driven by magnetic coupling with the turbine rotor (11A) and further magnetic couplings may be used to drive e.g. a propeller (15) for a micro air vehicle and/or electrical generator (16).
