Title: Improvements in straight bar knitting machines
IPC: D04B11/00
Filed: 1936-10-21
Abstract: 489,358. Knitting. LIEBERKNECHT GES., K. Oct. 21, 1936, No. 28604. Void. Convention date, Oct. 21, 1935. [Class 74 (ii)] Relates to straight-bar machines for knitting stocking blanks. In making the heels, the instep stitches are taken off the frame needles by an auxiliary bar 7 which retains the instep stitches until the heels are finished whereupon the instep stitches are transferred back again. The auxiliary bar 7 is mounted by long lateral support arms 9 on a vertically movable shaft 12 placed above the narrowing mechanism 25. The arms 9 are formed as double-armed levers and the points 8 carried by the bar 7 can be swung substantially horizontally in a circular arc of large radius about the shaft 12 by the action of cams 20, carried by a shaft 18, acting on trucks 22. The shaft 12 is moved up and down by cams 19, also carried by shaft 18. The shaft 12 is itself fastened to arms 10, rotatably mounted on a shaft 13. The bar 7 carries adjustable screws 7a which co-operate with guides 11 during the taking-off and putting-on of the stitches. After formation of the heel portions, when the bar 7 is not being used, the whole mechanism is swung up into the position shown dotted, the arms 9 being supported by resting pins 9a on the ends of arms 24; the entire mechanism may also be removed by detaching the support arm 14 from the bobbin board 15 of the machine. The auxiliary bar 7 may be replaced, when desired, by a welt bar and the shaft 18 moved to bring the appropriate cams (which it carries) into engagement with the trucks 21 and 22. When stitches are to be transferred to or from the instep needles, the points 8 are brought behind the needles so that they close their hooks and come to rest against the press edges 6. The bars can be swung out individually, or in groups for several sections.

Filed: 1968-06-18
Abstract: 1,202,159. Defluorinating phosphates. INSTITUT GAZA. 18 June, 1968, No. 28985/68. Heading Cl A. Defluorinated phosphate is made by bubbling the combustion products of a fuel through a melt of natural phosphate, the fuel being burnt within the melt. Additives, e.g. silica, may be added to the melt to lower the melting temperature, and phosphorus containing compounds, e.g. phosphoric acid, potassium metaphosphate, may be added to increase the phosphorus content. The fuel may be liquid, e.g. petroleum products, or gaseous, e.g. natural gas. If insufficient water is produced by the combustion of the fuel extra water vapour is bubbled through the melt. Phosphates with a fluorine content of less than 0À2% and a P 2 O 5  content of 37-41% may be prepared by the process. In an example apatite concentrate containing 3-3.5% of fluorine is defluorinated at 1500-- 1580‹ C. using natural gas as a fuel to a fluorine content of less than 0À15%. Suitable apparatus for carrying out the process is described, and the products may be used in fertilizers and animal foodstuffs.

Abstract: 384,747. Superposed telephony and telegraphy. LIGNES TELEGRAPHIQUES ET TELEPHONIQUES, 26, Rue de la PÚpiniÞre, Paris. Oct. 20, 1931, No. 29138. Convention date, Nov. 8, 1930. [Class 40 (iv).] In a two-way circuit balanced for frequencies used in telephony, fi 1 t e r s and/or amplifiers are provided passing a different frequency band in each direction, the different bands having a common band used for telephony and individual bands each used for another unidirectional communication. The circuit extending from A to B is balanced by networks 3. Signals in the direction A, B pass through network 5 and amplifier 1, which pass a frequency band of 300-3000 cycles per second, whilst signals from B to A are limited to the frequency band 100-2200 cycles per second by network 4 and amplifier 2. The band 300-2200 cycles is used for telephony, the system being balanced for this frequency range. Telegraphic signals pass from A to B using the frequency band 2200-3000 cycles whilst the band 100-300 cycles serves for telegraphic transmission from B to A. If telegraphic transmission from A to B only is required, a single network 4 with a cut-off at 2200 cycles is necessary, the band 2200-3000 cycles being used for the telegraphic transmission. The networks 4, 5 may be filters or resonant circuits tuned to the mean frequency to be passed, or the input transformers to the amplifiers may be arranged to provide the necessary frequency cut-off, in which case the filters are not provided. Although, as described, the two transmissions are telephony and telegraphy, either or both may be replaced by any other similar transmission.
