Abstract: The invention provides a modular wind power generation assembly comprising: a support tower; a modular structural framework mounted on the support tower; and a plurality of rotor nacelle assemblies mounted on the framework, wherein individual modules of the framework are connected or attached together to form an array of geometrically equivalent interstitial spacings in the modular structural framework and wherein the area swept by a rotor nacelle assembly rotor in its operation overlies a plurality of interstitial spacings in the framework.

Abstract: The apparatus comprises a vest 10 worn by a user 1 and having on its shoulders pivots 12 for an telescoping boom 20. A camera 38 is mounted on a standard mount 32 on a crossmember extending between side members 16 of the boom. A counterweight 28 provides balance to produce quasi-neutral positioning of the boom and camera and thus its ready pivoting by the user. Pistol grips 16, 18 provide for extension of the boom and panning/tilting of the camera. A monitor screen 36 allows the user to view the picture seen by the camera.

Abstract: An apparatus for ejecting material from a liquid has an ejection location 91) with an electrode (3). An electrical potential is applied to the ejection location electrode to form an electric field at the location together; liquid is supplied to the ejection location which contains the particulate material to be ejected from the ejection location. A secondary electrode (5, 8) is disposed adjacent to the ejection location and the voltage on the ejection location electrode is controllable so as to reduce the sensitivity of the head to influence by external electric fields.

Abstract: An apparatus and method are described for supplying material to a substrate (109). The apparatus includes a member (3) having a surface with a plurality of features (8) which locate, in use, menisci of a liquid (1) supplied to the member. An actuator (4) induces mechanical vibrations within the liquid located by the features to cause liquid droplets (7) to be sprayed. Liquid (1) is supplied to the member and electrical charge is supplied to the member and electrical charge is supplied to the liquid by, for example, an electrode (14). Electrical charge or potential is also supplied to the substrate (109) so that the droplets are directed towards the substrate to deposit material thereon.

Abstract: A method of depositing material on a surface (136) is described in which a bulk medium (for example ink 122) in the form of a composition of dispersed insoluble material (for example ink particles) and a support medium is supplied to a cell (120). A movement of the insoluble material within the bulk medium is effected towards a transfer aperture (128) within the cell, thereby concentrating the insoluble material within the bulk medium. Thereafter the insoluble material is removed from the concentration within the bulk medium through the aperture (128) and deposited onto the surface (136).

Abstract: A device for generating droplets of fluid has a fluid supply reservoir and an electromechanical transducer. Electrodes are arranged to cause expansion and contraction of the transducer in a dimension perpendicular to the applied electric field. A perforated element is coupled for movement with the expansion and contraction of the transducer and is positioned for contact with the fluid supply for dispensing droplets therethrough.

Abstract: A movement sensor (40) for a process device has a sensor tip (42); means (41) for transmitting the vibrations from the sensor tip to a transducer means (43), the transducer means electrically detecting the resulting vibrations as movement occurs and producing an output signal. Means (70) can be provided for filtering the output signal below and above respective predetermined frequencies and producing a movement detection signal when the output signal lies between the predetermined frequencies.

Abstract: An inlet line connected to the inlet of a hydraulic pump includes a jet pump having a Venturi nozzle though which the aspired liquid is passed, and into which a coaxial jet of liquid under higher pressure is introduced to raise, by jet-pump action, the pressure of the liquid at the pump inlet.
