    • In dyeing keratinous fibres, such as wool, by impregnating the fibres with aqueous compositions containing dyes, followed by storage in the moist condition, a higher level of fixation, enabling heavier shades to be obtained with cheaper dyes, can be achieved by raising the temperature of the stored fibres by means of radio frequency heating. The storage temperature is preferably between 40.degree. and 80.degree. C., which usually requires about 0.05 kw hour/kg fibres. Acid, milling, chrome and premetallized dyes can be used, as well as reactive dyes and substantive optical brighteners. The fibres are cuttled into an insulated plastics material cart located between a pair of electrodes in an r.f. chamber. One electrode is fixed and the other is adjustable so that the r.f. load acting on the fibres may be set at a desired value.
    • 在染色角质纤维如羊毛时,通过用包含染料的含水组合物浸渍纤维,然后在潮湿条件下储存,可以获得更高水平的固色,从而可以通过提高较低的染料来获得较重的色调。 的存储光纤通过射频加热。 储存温度优选在40℃至80℃之间,通常需要约0.05kw小时/ kg纤维。 可以使用酸,碾磨,铬和预金属化的染料,以及活性染料和实质荧光增白剂。 纤维被切割成位于r.f中的一对电极之间的绝缘塑料材料车。 房间。 一个电极是固定的,另一个是可调节的,使得r.f. 可以将作用在纤维上的负荷设定为期望值。

    • A document feed system is disclosed which comprises a feed wheel (10) mounted on a first rotatable shaft (13), and a retard wheel (11) mounted on a second rotatable shaft (14). The first shaft is driven by a motor and the second shaft is mounted in a bearing fixed in a pivoting arm. A first pulley (17) is fixed on the first shaft and a second pulley (19) is coupled to the second shaft through a slipping clutch (18). A belt (20) passes round the first and second pulleys and also round an idler pulley (21) which is rotatable on a spring loaded shaft (22). The arrangement is such that the belt (20) pulls the first and second shafts towards each other so that a document may be gripped between the feed and retard wheels. If a single document is located in the nip between the feed and retard wheels it will be driven in the direction of the arrow (24). However, if two documents are located side by side in the nip, one document will be driven in the direction of the arrow (24) while the other is retarded relative to that document.

    • The present invention provides a method and apparatus for evaluating the porosity of a sheet material at a given value of gas flow or pressure drop (PD), with account being taken of the following relationship between the parameters of flow and PD:Flow=A (PD).sup.N,in which one of the parameters is set at a number (e.g. 3) of values close to the said required value, the other parameter is measured at each, the values of A and N for the sample under test are calculated therefrom, and then the precise gas flow (or PD) at the given PD (or gas flow), and hence the porosity, is calculated from the said relationship. The automatic setting, and the calculations, are effected by means of a microprocessor.

    • Systems and methods for reducing wind pressure on wind turbine blades by selectively opening excessive wind portals in the turbine blades. One embodiment comprises a wind turbine system in which each of the turbine's blades has a portal therethrough that is opened or closed by a movable panel. Each panel is connected on one edge to the corresponding blade at the edge of the portal. Hook-and-loop material (Velcro) is attached to the edges of each portal and panel, allowing the panels to alternately open and then close the portals over a series of high wind events. Excessive wind pressure forces the panels to be released, opening the portals. Gravity or reversed wind direction with respect to the blade can be used to reseal the panels.
    • 通过选择性地打开涡轮机叶片中的过多风门来减小风力涡轮机叶片上的风压的系统和方法。 一个实施例包括风力涡轮机系统,其中每个涡轮机的叶片具有通过可移动面板打开或关闭的通过其的入口。 每个面板在一个边缘连接到门户边缘的相应刀片。 钩环材料(Velcro)连接到每个门和面板的边缘,允许面板通过一系列高风事件交替打开并关闭门户。 过大的风压迫使面板被释放,打开门户。 可以使用相对于叶片的重力或相反的风向来重新密封面板。
