    摘要: A process is provided for the preparation of dibasic propellant charge powder by a solvent-free process, in which a continuous flow of raw powder mixture moist with water is kneaded at an elevated temperature in a set of shearing rollers, to which the raw powder mixture is continuously supplied and at one end of which the gelatinized mass is continuously removed and immediately continuously granulated. The resulting granulate is continuously delivered to an extruder by means of which it is moulded into powder strands which are worked up into the finished powder by cutting and an end treatment. The process requires only small quantities of powder within the kneading equipment and thus provides a safe and efficient continuous manufacturing facility.

    摘要: An open mill or mixer for the processing of rubber and plastics comprises an additional or third roll for a higher productivity and, when upstream of the open mill a closed mixer is provided, for a readier cooling of the mixture. The two usual rolls are not placed at the same level, but one is slightly upper, while the third additional roll engages the lower one in the bottom part thereof. The angle formed by the lines joining the center of this latter with the centers of the other two rolls is comprised between 60.degree. and 120.degree. and is preferably of 80.degree.-90.degree.. Also the third roll is motor-driven, as well as the other two and has a higher peripheral speed than the roll which is wrapped up by the mix sheet and has the lower speed. The additional roll is provided with quick approachment means, such as cylinder and piston means, and fine adjustment means for adjusting its distance to the roll with which it is designed to engage, whereby when said approachment means is in a retracted position, the mixer conventionally operates with only two rolls.

    摘要: A DEVICE FOR ATTACHMENT TO A RUBBER MILL IS PROVIDED WHICH INCLUDES PARTITION MEANS AT THE ROLL ENGAGEMENT ADAPTED TO DIVIDE THE ROLL NIP INTO TWO OUTER ZONES FOR RECEIVING THE RUBBER TO BE MILLED AND A MIDDLE PREHEATING ZONE FROM WHICH A STRIP OF MILLED RUBBER IS CUT OUT FOR CONVEYANCE TO THE NEXT PROCESSING STATION, ADJUSTABLE ROLLER MEANS PARALLEL TO BUT SPACED FROM THE ROLL ENGAGEMENT ADAPTED TO DEFLECT THE REMAINING CUT APART WEBS TOWARDS THE MIDDLE ZONE OF THE ROLL NIP FOR PREHEATING, AND CONTROL MEANS COMPRISING A FEELING MEANS IN SAID MIDDLE ZONE FOR DETERMINING THE AMOUNT OF RUBBER MATERIAL THEREIN, AND LINKAGE MEANS CONNECTED TO SAID FEELING MEANS WHICH TRANSMIT TO SAID ROLLER MEANS THE AMOUNT OF ADJUSTMENT THEREOF NEEDED TO DEFLECT AN APPROPRIATE AMOUNT OF SAID CUT APART WEBS TOWARDS SAID MIDDLE ZONE FOR PROCESSING AT THE NEXT STATION. THE ATTACHMENT MAY ALSO INCLUDE A CUTTING AND JOINTING DEVICE WHICH COMPENSATES FOR ACCUMULATION OF MILLED RUBBER STRIP MATERIAL DURING STOPPAGES AND DELAYS AT SAID NEXT PROCESSING STATION.
