Abstract: 355,062. knitting-machines. SCOTT & WILLIAMS, Inc., 366, Broadway, New York, U.S.A.-(Assignees of Page, A. E. and Page, F. R.; Brooklyn, New York, U.S.A.) Sept. 12, 1930, No. 27319. Convention date, Sept. 12, 1929. [Class 74 (ii).] Relates to a machine for automatically knitting the stocking of Specification 317,184, [Class 74 (ii), Knitting &c.], and is described in connection with a machine wherein the heel and toe pockets are knitted upon opposite halves of the circle of needles as in Specification 328,830, [Class 74 (ii), Knitting &c.]. A reduced heel may be made as described in Specification 246,113, [Class 74 (ii), Knitting &c.]. The needles for the toe pocket are divided into groups N<2> .. N<6>, of which the needles N2, N<3>, N<6> have shorter butts than the needles N<4>, N<5>. The gussets G are formed between the narrowing and widening segments C, D of the toe pocket by providing means for restoring, as groups, the needles N4, N<5>. The narrowing at the inner end H of the gusset is effected by the usual narrowing pickers. Lowering cams 24, 26, 27. 28, and raising cams 25, 29, additional to the usual knitting cams, and controlled by lugs upon the usual main pattern drum are provided for actuating the needles. In operation, the cams 25, 27, 28 are brought into action when the round-and-round knitting for the instep has been completed, and raise the heel pocket needles N<1> to inactive position without raising the needles N<2> .. N<6>. Upon withdrawal of the cams 25, 27, 28, the pickers 650 narrow the segment of active needles until only the group N<6> remains. The cams 26, 28 at this stage restore the needles N<4>, N<5> to form the gussets G, and after the tapered end H of each of the gussets has been formed by raising needles by the pickers 650, the remaining active needles N<4>, N<5> are raised so that the bottom segment of the toe can be knitted. This needle raising is effected by the cam 25 which is pushed in sufficiently far as to engage only the long butts. The lowering cam 24 and raising cam 25 are controlled by a rod 216, which also actuates the widening picker 680. The cam 24 is adjustable to positions wherein it can actuate only the long butts, the long and intermediate butts, and all the butts, or to a position wherein it is inoperative. Specifications 12722/13 and 102,711, [both in Class 74 (ii), Knitting &c.], also are referred to.

Title: Improvements in the manufacture of highly fluorinated aromatic compounds
Inventor: STACEY MAURICE
IPC: C07B39/00
Filed: 1958-11-05
Abstract: Aromatic fluorocarbons and fluorinated aromatic hydrocarbons containing not more than 3 hydrogen atoms per aromatic nucleus are produced by defluorinating alicyclic fluorocarbons or fluorinated alicyclic hydrocarbons containing at least one cyclohexane or cyclohexene ring, each ring having attached to it at least 9 or 7 fluorine atoms respectively, by passing the vapours of the compound to be defluorinated, preferably at a temperature of 350 DEG  to 600 DEG C., over nickel, iron, cobalt or copper.  In the examples, the vapour is carried by a stream of nitrogen through a heated nickel tube packed with small pieces of iron gauze.  After each reaction the metal fluoride, formed by the defluorination process, is reduced to the metal by means of hydrogen.  In Example 1, undecafluorocyclohexane is heated at 530 DEG C. yielding a mixture of hexafluorobenzene and pentafluorobenzene.  Examples 3, 4 and 13 relates to the production of hexafluorobenzene by heating decafluorocyclohexene, nonafluorocyclohexene and perfluorocyclohexane, respectively.  Other examples relates to the production of perfluorotoluene, 1,2,3,4-tetrafluorobenzene, the three perfluoroxylenes, perfluoromesitylene, decafluoroethylbenzene, decafluorodiphenyl, and octafluoronaphthalene.  It is mentioned that fluorinated dicyclohexyl methanes and tricyclohexyl methanes can be defluorinated to yield fluorinated diphenyl-methanes and triphenylmethanes, respectively.

IPC: C07F9/12
Filed: 1963-09-11
Abstract: The invention comprises neutral organic amine and alkaline earth metal salts of phosphate esters of 3-pentadecylphenol, the phosphate esters being primarily mixtures of primary and secondary phosphates with a small amount of tertiary phosphate. They may be prepared by heating 3-pentadecylphenol with polyphosphoric acid for 5 hours, in the absence of a solvent, at 115 DEG  C., and neutralizing to a pH of 7 to 7.7 with an alkali metal hydroxide or an organic amine such as cyclohexylamine, aromatic amines or alkyl or dialkyl amines. The mixture may be rendered anhydrous by heating under vacuum.  The products are used as corrosion inhibitors.  Comparative examples describe the preparation of the potassium salt of a phosphate of a pentadecylphenol-ethylene oxide condensate and the sodium salt of a phosphate of a nonylphenolethylene oxide condensate.ALSO:Lubricating and fuel compositions comprise as corrosion inhibitors neutral organic amine or alkaline earth metal salts of phosphate esters of 3-pentadecylphenol.  The salts may be added to mineral lubricating oil, a high boiling hydrocarbon (initial b.pt., 375 DEG  C.) or petroleum ether (b.pt., 90-100 DEG  C.).  From 0.5 to 2.0% by weight of salt may be added.  Amine salts may be derived from cyclohexylamine, aromatic amines or mono- or di-alkylamines.ALSO:Neutral organic amine or alkaline earth metal salts of phosphate esters of 3-pentadecylphenol are used to inhibit corrosion of metals, specifically iron, steel and ferrous alloys, by, for example, water, brines, weak inorganic acids, organic acids, carbon dioxide and hydrogen sulphide.  The inhibitor may be applied to the metal either by itself or in a carrier, but is preferably dissolved in the corrosive solution.

Abstract: 910,417. Phase modulation. GENERAL ELECTRIC CO. Ltd. Jan. 20, 1961 [Oct. 23, 1959], No. 35982/59. Class 40 (5). [Also in Groups XXXIX and XL (b)] A transmission line is associated with a " magnetic thin film " with the magnetic signal field of the line perpendicular to the magnetization of the film. " Magnetic thin film " comprises a layer, e.g. 5000 Š thick, of ferromagnetic material magnetized in one or the other sense along an " easy axis." Such a film exhibits a hysteresis loop which is rectangular along the easy axis and linear perpendicular to this axis. The strip 1 is vacuum-coated with magnetic material whilst a magnetic field of about 50 oersteds is applied in a direction parallel to its length. The other strip 2 is anodized. The strips 1, 2 are mounted on a glass plate 3 and a sheet of neoprene 4, the sheet being then clamped to the plate. In a modification, the magnetic thin film is initially magnetized at right-angles to the length of the strip. The delay line assembly is arranged on the axis of a solenoid to which current is applied to rotate the magnetization of the film parallel to the length of the line. Further increase in current modulates the signal in the line. In Fig. 5, the line 15 comprises two parallel aluminium-foil strip-conductors wound around a cylindrical former 16. The ends of the line are tapered and joined to coaxial leads 17, 18. A bias or modulating coil may be wound toroidally over the former. In this case, the magnetic thin film is magnetized across the width of the strip. In Fig. 6, one conductor consists of aluminium plate 20 coated with magnetic thin film between the lines 21, 22 and with a film of tapered thickness between the lines 21, 23 and 22, 24. The film is magnetized in the direction of the arrows 25. The second conductor 26 consists of an anodized strip of serpentine form. The plastic film, bearing the strip conductor, is held in position by a pressure-pad 29 of neoprene. The line may be used as a modulator or parametric amplifier by surrounding it with a field winding consisting of a flat-strip conductor wound into a flattened helix. The magnetic thin film may be initially magnetized at right-angles to the arrow 25 and subsequently re-oriented by a field winding.

Title: Improvements in joining devices for binding strip
IPC: B65B13/30
Filed: 1964-09-03
Abstract: 1,048,598. Strip-tensioning devices. A. FROMM G.m.b.H. Sept. 3, 1964 [Sept. 3, 1963], No. 36197/64. Heading F2G. A strip-tensioning and joining device, e.g. for binding a packing case comprises a clamp for clamping together two parts of the binding strip, a displaceable die co-operating with a. fixed die for joining the two parts of the strip, a toggle linkage supporting the movable die and a wedge actuated by a pneumatically driven piston and co-operable with the linkage to effect a joining operation. As described, compressed-air passes through a valve in a handle 1 (Fig. 1, not shown), to a head-piece 5 containing a rotor adapted to rotate a gearwheel 13, which in turn rotates a gear-wheel 14 and a tension ring roller 17 which is mounted on the same shaft 15 as the gear-wheel 14. Shaft 15 is journalled in rocker 16 (Fig. 6, not shown), spring-loaded to press roller 17 towards a base plate 21. Mounted in the base plate 21 is a housing 22 carrying a movable die 44 cooperating with a fixed die 49 on plate 21 and attached via a punch 43 to a toggle linkage 41, pivotally mounted on the punch. The upper end of the toggle 41 carries a freely-rotatable roller 40 resting against roller 37 in the inoperative position. To the centre of the toggle is connected one end of a link 46 pivoted about pin 47 and a spring 48 keeping the toggle against roller 37. Above the housing 22 is a cylinder 28 containing a piston 32 and connected to the compressed-air source via a line 12, a valve in a housing 7 and a line 11. Secured to the piston is a wedge 34 adapted to pass between the rollers 37, 40. In operation, compressed-air is passed to the rotor after the strips have been placed between the two dies and between roller 17 and the base plate 21. The rotor causes roller 17 to tension the strip. The air pressure is released and the spring-loaded rocker causes the roller 17 to maintain the tension in the strip. Compressed-air is then passed to cylinder 28 to force the piston and wedge downwardly and cause the toggle to be moved leftwardly (Fig. 3) and the die 44 downwardly to stamp notches into the strip (Fig. 8, not shown). At the same time the end of the strip may be severed. A safety lever 57 (Fig. 7, not shown), may be used to keep the strip in position between the dies.
