Abstract: 688,327. Fusible cut-outs. GENERAL ELECTRIC CO., Ltd. Oct. 29, 1951 [Nov. 16, 1950], No. 28063/50. Class 38 (i). A high-voltage fuse element comprising a plurality of fusible lengths connected in series by solder joints, alternate sections being of one current-carrying capacity and the other sections being of a greater current capacity with sections of greater capacity at the ends of the element, is characterised in that there are at least two smaller and three greater current-carrying capacity sections, and the solder of at least the joints of the outer greater capacity sections to the adjacent smaller capacity sections is of high melting point, whilst at least one central section is joined to its adjacent sections by low melting point solder. A fuse element 1 comprises three heavy-gauge sections 2 of silver wire soldered to two thinner silver sections 3, the end sections being connected to cartridge fuse caps 4. The element 1 is about 10 inches long and arranged to be wound on a starsection porcelain former, three such elements being connected in parallel for use on 50 amps., 1500 volts D.C. To ensure that low current circuit interruption takes place towards the fuse centre, a high melting point silver solder is used for the joints 8, 9, whilst a low melting point tin or tin alloy solder is used for the joints 6, 7. According to Fig. 2 (not shown), the element may comprise four heavy-gauge sections 2 and three thinner sections 3. The joints may be simple lap joints, Fig. 3 (not shown), or the ends of the sections may be bent to cross over one another and be encased in a solder blob, Fig. 4 (not shown). The different current-carrying capacities of the sections may alternatively be obtained by using sections of the same cross-section but of different materials, or the sections may be both differently composed and have different cross-sections.

Title: Automatic control system for producing oil bearing carbon black
IPC: C01B32/384
Filed: 1966-06-27
Abstract: In a continuous and automatic process for pelleting carbon black in which the black is first wetted with a liquid, the flow rate of liquid is adjusted to maintain a predetermined ratio between it and the weight of the wetted black. Carbon black may be produced by combustion of hydrocarbons and is separated and fed via a surge tank, and one single or two tiered screw conveyers or a star valve or vibra screw, to pin mixers, where it is sprayed with oil.  The black is then fed on to a weigh belt and pelleted in a rotary drum.  Flow rate of oil (measured via pressure differential across an orifice) and weight of black are converted using transducers into pneumatic signals.  These signals are compared in a controller, and if there is any divergence from the required ratio, the flow rate of oil is adjusted via a pressure-responsive valve. Air is supplied for operating the pneumatic devices.  Alternatively, an electro-mechanical transducer (e.g. a potentiometer) and a servomechanism controller may be used, and a comparison made of voltage instead of gas pressures.
