Abstract: A dry or like cooling apparatus and method primarily for an air conditioning system is provided in which a heat exchanger or cooler (32) is subjected to an air stream (A) for transfer of heat from fluid e.g. water in the cooler (32) to the air and in which a fine spray or mist of water is introduced into the air stream (A) so as to be substantially absorbed by the latter. As a result the air stream is adiabatically cooled for effecting a considerably improved cooling action on the cooler (32) especially under conditions of high ambient temperature e.g. in the region of 30°C. The water spray may be intermittent or pulsed and may be controlled in dependence on the temperature of the water passing through the cooler (32) and/or of the air stream. Since mains water can be used and any slight deposition of water soon dries there is little or no risk of Legionella bacteria breeding as compared with a wet cooling tower whilst the apparatus occupies considerably less space than a dry cooler.

Abstract: 5 n7 This invention is a process of contactless monitoring the tension in a moving fiber, such as during the process of drawing optical fibers from preforms, and a non-contacting tension gauge which allows measurement of fiber tension at line speed. The device can be used to monitor the tension during the run without any adverse effects on fiber performance. The measurement may be steady, intermittent or sinusoidal as appropriate. The process includes the steps of sensing an initial position of a moving optical fiber, applying a gas jet onto a section of the optical fiber in a direction transverse to the direction of movement of the fiber so as to cause deflection of the moving fiber axially of the gas jet, sensing the magnitude of deflection of the fiber relative to the said initial position, and, depending on the magnitude of deflection, adjusting the tension in the fiber so as to cause the change in the magnitude of deflection to a preselected value. The monitoring is especially suitable for monitoring the tension in an optical fiber being drawn from a heated preform, the tension being adjusted by adjusting the temperature of the fiber-drawing furnace.

Abstract: The invention makes it possible to drive a halftone image recording device and achieve high halftone reproduction by allowing at least one of the leading and trailing edges of a pulse width-modulated signal applied to a recording head, or forming amplitude- and width-modulated pulses, respectively, as driving pulses for placing one dot under halftone control, and changing a pulse width change of pulse width modulation in a stepwise manner, using the pulse width of the amplitude-modulated pulse as a unit pulse width. 
     The invention intends to achieve high-voltage and high-speed pulse output and low power consumption by converting input data such as halftone image data to a voltage signal, superposing pulse voltages of opposite polarities and applying the resulting signal to a switching circuit constituting an output state in the form of a switching signal, and also makes it possible to achieve high speed and high-voltage driving by connecting at least one of equivalent two-terminal elements in series to at least one of the respective driving elements of a complementary FET driving circuit, said equivalent two-terminal elements are each put on with a current of a certain or higher value passing therethrough to show constant-voltage characteristics and put off with a current of a certain or lower value passing therethrough to become a constant resistance.
