Patent GB-937101-A (GB)
Title: Improvements relating to devices for adjusting the selector bits in pattern wheels for circular knitting machines
IPC: D04B15/76
Filed: 1960-02-29
Abstract: 937,101. Knitting apparatus. FRANZ MORAT G.m.b.H. Feb. 29, 1960, No. 7025/60. Class 74 (2). A pattern wheel of the kind described in Specification 859,196 has the position of its selector bits determined by a device on which the wheel is positioned after it has been removed from a circular knitting machine. The device comprises a circular housing 1 in which the pattern wheel is positioned after it has been removed from the machine and after its top cover, which secures the selector bits in either their operative or inoperative positions, has been removed and all of the selector bits moved to what is normally their outer operative position. An extension 1a of the housing accommodates two finger-operated plungers 5, 6, one, 6, of which is formed in two parts 6b, 6c capable of independent movement, and the other, 5, of which carries a fork 12 adapted to engage the portion 6b so that when the part 5 is moved the lower portion 6b of the plunger 6 also is moved. The lower end of each plunger is of conical formation and when lowered each is adapted to engage and project a slidable bolt 13, 15, one, 13, of which has its end formed to engage a selector bit in the pattern wheel as it is projected to move the bit to its inner inoperative position, whilst the other bolt 15 carries at its end a pawl 18 which engages in a trick in the pattern wheel and rotates it the distance of one trick. Consequently, having positioned the pattern wheel in the housing the positions of the selector bits can be set by either pressing plunger 5 or 6. In the first instance the lower portion 6b, which is lowered by fork 12 as the plunger 5 is pressed, causes rotation of the wheel the distance of one trick, whereafter the lower portion of plunger 5 then engages its bolt 13 to cause the end of the bolt 13 to push the adjacent selector bit back into its inner inoperative position. In the second instance when the plunger 6 is pressed the trick wheel is merely rotated the distance of one trick and the corresponding selector bit remains in its outer operative position. The whole wheel can thus be set up for patterning.

Abstract: 248,186. Ganahl, C. de, and Koch, F. C. March 16, 1925. Hydrocarbons, distilling. - Apparatus for the fractional distillation of petroleum and its products or the products, such as benzol and zylene, of the destructive distillation of coal, comprises a series of dephlegmator towers 19 and pairs of receptacles 39, 42, the oil condensing in the tower collecting in the receptacle 42 and being pumped through the furnace 44 into the receptacle 39 where the volatile constituents pass off. The residuum in the receptacle 39 is pumped into the next still in the series operating at a higher temperature. The receptacles may be connected by a pipe 40 and valve 41. The charge oil is supplied by a pump 1.and valve controlled pipes 13, 15, 16 to heat exchangers 20, 21, 22 and a pipe 3 from which it may be led to the tower by any one of a series of valve controlled pipes 18 or alternatively directed to the furnace 44 by the pipe 38. The vapours from the tower are led by the pipe 6 to the heat exchanger 20, condenser 25, and collecting tank 30 from which a proportion may be pumped to the top of the tower for the necessary cooling. Alternatively the cooling may be obtained by passing the cold charge through a closed coil in the top of the tower. The residuum in the receptacle 39 is treated in a similar apparatus for the removal of a higher-boiling fraction, preferably being passed through a heat exchanger 28 by which its temperature is raised. In the construction shown the residuum from the second apparatus passes through the heat exchanger 28, and to either the heat exchanger 21 or cooler 26 as desired, and the vapours pass through the heat exchanger 22 and condenser 27 to the collecting chamber 32. In the treatment of heavy crude oil or other hydrocarbon mixture which is likely to deposit foreign matter and coke in the tower the charge is led directly to the furnace, the foreign matter being deposited in the receptacle 39 which can be opened and cleaned.
