  • Patent number: 9010156
    Abstract: In the case of a single circular knitting machine consisting of a central rotatable needle cylinder (Z), around which a sinker ring (PR) comprising sinkers (P) as well as stationary cam systems (S) are arranged, which act on the needles (1), which are in each case assigned to the sinkers (P) and which can be moved vertically up and down, so as to replace the pitches, which hit one another rigidly, with a sinker grid system, which is flexible per se, which is automatically oriented in the needle gaps, a rocker (44) comprising an upper and a lower control bump (45) being provided in each case on the end of the sinkers (P), which is spaced apart from the needle, the sinker ring (PR), at the end below the sinkers (P), which is spaced apart from the needle, is embodied as a pivot point projection (40) comprising pivot point slits (41), in which the sinkers (P) are accommodated with their pivot inlet (43) so that they are capable of being tilted and the sinkers (P) being are laterally fixed in the needle gaps with

  • Patent number: 4183725
    Abstract: In a method of melting glass in burner-heated glass melting tanks wherein preheated pellets comprised of quartz, sand, sodium carbonate, potassium carbonate, lime, and magnesium oxide ae injected by a pressurized gaseous medium into a glass melt contained in the tanks, the improvement comprising injecting the pellets in a manner adapted to form a veil-like formation above the melt extending over substantially the entire melt surface and over substantially all of the burner flames.
