    • A roll caster comprising a pair of rotatable rolls (1, 2), and mounting means (4, 5) for moving one of the rolls towards and away from the other, so as to adjust the gap between the rolls. A nozzle assembly (9) for directing molten metal into the gap between the rolls, is mounted with its outlet end projecting into the gap, with a suitable clearance. The nozzle assembly is mounted on a carrier (13) which is moved in accordance with the movement of the rolls, by means of a mounting comprising movable links (16, 17) so as to maintain the required clearance between the nozzle and the rolls.

    • An apparatus for the prevention of ice dams on roofs of edifices comprising a ventilator, a first and second outdoor temperature sensor. The first temperature sensor is located outside where snow will not collect. The second outdoor temperature sensor is located on the roof of the edifice where snow will collect. Both sensors are housed to protect the sensors from extreme weather conditions, such as sun and wind. The apparatus also comprises a thermostat for receiving the temperature readings from the first and second temperature sensors and manipulating the ventilator. The apparatus also provides a method of preventing ice dam formation on roofs of edifices, comprising the steps of detecting a first temperature reading of the ambient atmosphere, detecting a second temperature reading of the roof of the edifice, comparing the readings to determine whether conditions exist for ice dam formation, ventilating an air space below the roof of the edifice to cool the roof if ice dam conditions are present.
    • 一种用于防止顶板上的冰坝的装置,包括通风机,第一和第二室外温度传感器。 第一个温度传感器位于雪不会收集的外面。 第二个室外温度传感器位于雪地收集的大厦的屋顶上。 两个传感器都被安装在保护传感器的极端天气条件下,如太阳和风。 该装置还包括用于接收来自第一和第二温度传感器的温度读数并操纵呼吸机的恒温器。 该装置还提供了一种防止在屋顶上形成冰坝的方法,包括以下步骤:检测环境大气的第一温度读数,检测建筑物屋顶的第二温度读数,比较读数以确定条件是否存在 对于冰坝形成,如果存在冰坝条件,则在大厦屋顶下方的空气通风通风以冷却屋顶。
