摘要： An internal mixer has two rotors operated at either the same speed or different speeds. In two communicating cylindrical closed spaces which are round in cross section, two rotors connected with two output shafts of a speed reducer are juxtaposed in a non-engaged state, to transmit the driving power from the prime mover to the speed reducer, thus turning the two rotors in opposite directions. In this internal mixer, the two rotors are usable both at the same speed and at different speeds because of the use of the speed reducer having two output shafts whose speed of revolution is changeable between the same speed and different speeds. In one embodiment, the speeds of revolution of the output shafts are changed by a slidable clutch and in another embodiment, the speeds of revolution are changed by a movable stepped gear.

摘要： A kneading machine has a cylinder formed with upper and lower ports for compressed fluid, a piston slidably fitted in the cylinder and having a weight connected to the underside thereof, a case disposed under the cylinder and having an upper opening to be closed and opened by the weight and kneader blades disposed within the case. An overload preventing system is provided and includes an upper pipe extending from a compressed fluid feed source to the upper port. A solenoid valve and the upper pipe selectively communicates the upper port with either the atmosphere or the compressed fluid feed source. Similarly, a lower pipe has a solenoid valve for selectively connecting the lower port to either the atmosphere or the compressed fluid feed source. A connecting pipe connects the upper and lower ports and includes a solenoid valve which selectively closes the connecting pipe. A kneader relay monitors the load of the motor which drives the kneader blades. When an overload is detected, the solenoid in the connecting pipe is opened so that the pressures on either side of the piston are equalized, thereby reducing the closing force of the weight and also reducing the motor load.

摘要： An apparatus in which a glass rod is inserted into a spinning oven to perform spinning and glass fiber yarn is drawn out at a shutter located in the lower end of the spinning oven, comprising a timer for measuring a time from the start of heating of the glass rod inserted into the spinning oven until the fall of glass drops formed by the heating of the glass rod and a detector below the shutter for detecting the fall of the glass drops, for the purpose of automatically opening the shutter when a preset time of the timer is over and automatically closing the shutter by detection by the detector, thereby dispensing with a worker's monitoring of the spinning oven for opening and closing the shutter and preventing a danger of giving damage to the shutter and the spinning oven in the event of delayed shutter opening-closing timing.
