Abstract: In order to securely hold a moving belt (1, 2) of a continuous casting device against selective movable side plates (5, 6), a first group of rotatable control rods (19, 19A) which are disposed in a first supply header (16) and an adjacent exhaust header (17) are arranged to produce narrow high pressure zones in the cooling film (12) defined between the cooling pad (9) in which the headers (19, 19A) are formed and the moving belt (1 or 2). These zones can be selectively moved so as to follow and juxtapose the side plates (5, 6) when the mould gap between said plates is adjusted. A second group of rotatable control rods (19B, 19C) which are disposed in second and third supply headers (16) selectively heat the side portions of the belt (1 or 2) which are relatively cool as compared with the center portion thereof which is exposed to molten metal. When the side plate (5, 6) are moved away from each other the width of the belt side portions exposed to preheated coolant can be reduced and the amount of normal temperature coolant applied to the center portion thereof can be increased.

Abstract: The mass to be extruded is forced into an extrusion duct (die) (1) so as to make it emerge in the extruded state from the outlet end (3) of the duct in a direction (2) generally-axial of the duct itself. An annular flow of fluid is generated around the outlet end (3) of the extrusion duct (1), oriented in an axial direction relative to the extrusion duct (1), and surrounds the extruded mass, preventing it from bending accidentally. The extruded mass is divided into pieces by a cutting operation (9) carried out within (7) the zone in which the annular flow of fluid acts.

Abstract: A measuring mixer for use with either liquids or powders in which different supply systems supply different stock liquids or powders to a receiving container from supply containers. A continuously variable flow regulator is associated with each supply container. The cumulative weight of the receiving container is measured and compared with a target weight. Then a computation section calculates a desired flow rate based upon both the deviation from the target weight and a time variation thereof. This calculation is preferably done according to fuzzy inference. The desired flow rate is then used to control a selected one of the flow regulators so that the measurement is sequentially performed between supply systems. Optionally, the receiving container can be movable between the different supply systems.

Abstract: A belt tensioner (42) having a sleeve bearing (60) pivotally mounting a pivoted structure (68) on a fixed structure (46) for spring pressed movement between first and second positions. The sleeve bearing (60) is larger than and surrounds a ball bearing assembly (84) rotatably mounting a pulley (88) on the pivoted structure (68). The pulley has a cantilevered rim (94) which axially overlaps and annularly surrounds the sleeve bearing. One of the structures and the sleeve bearing have slidably interengaging surfaces which are compressed together by the belt load force in the pivoted structure and the reactionary force acting in the fixed structure so as to provide a damping torque resistance to the pivotal movement of the pivoted structure which prevents movements resulting from dynamic changes in the belt load force within a range. The arrangement is such that independent vibrational forces instantaneously release the damping torque resistance to permit instantaneous movements otherwise prevented.

Abstract: An ultrasonic ice presence detector includes a transmit/receive piezoelectric sensor (10) coupled to one end of an acoustic delay line in the form of a rod (20) with the other end (26) of the rod co-aligned with the surface of an aerofoil (18). The transducer is excited by an electrical pulse to transmit an ultrasonic pulse along the rod to the sensing surface (26) as a function of the acoustic impedance at the sensing surface/air interface. When ice accumulates on the sensing surface, the acoustic impedance at the interface is altered to change the magnitude of the reflected energy. An acoustic discontinuity (30) of known characteristics is provided in the acoustic delay line (20) so that the magnitude of a first reflected pulse of known characteristics is sensed by the transducer and compared with the magnitude of a second, following pulse representative of the acoustic impedance at the sensing surface (26), thereby enabling self-calibration of the system during each cycle so that sensing is independent of various error sources in the system.

Abstract: A method of measuring a profile of an object wherein an ultrasonic wave is radiated from an ultrasonic transducer toward an object supported by a supporting member in the water filled in a water tank, and a wave reflected at the surface of the object is detected by the transducer, and an apparatus for carrying out the method. A traversing device moves the transducer sequentially to a plurality of measurement points on an arc equidistant from a predetermined rotational center while opposing the transducer to the predetermined rotational center. A supporting device moves the supporting member relative to the transducer and sets the object in the predetermined position under water. A control device delivers a drive signal to the traversing device to move the transducer sequentially to the measurement points, causes the transducer to radiate an ultrasonic wave when the transducer is in each of the measurement points, calculates a distance between the transducer and the surface of the object in accordance with a difference between the time the transducer radiates the ultrasonic wave and the time transducer receives the wave reflected at the surface of the object, calculates coordinates of each of the measurement points, and coordinates of the surface of the object corresponding to each of the measurement points from the calculated distance, and obtains the profile of the object from the calculated coordinate of the surface of the object at each of the measurement points.
