Filed: 1940-11-25
Abstract: 544,315. Heel-attaching or building machines. POCHIN, H. W., and BROMLEY, J. H. Nov. 25, 1940, No. 16896. [Class 17 (i)] Heel clamping means, in a heel attaching or heel building machine comprises hydraulic means for lightly clamping the heel, means for thereon trapping the hydraulic fluid, and mechanical means for applying further clamping pressure through the medium of the trapped fluid. The upper member b of the clamp is reciprocated by a lever c actuated by a piston e in a cylinder carrying a spigot h' in screwthreaded engagement with a sleeve h bored to engage a plunger h<SP>2</SP> carried by an eccentric strap g. On work being.positioned a treadle o is depressed, thus actuating a valve rod n admitting fluid at low pressure to the cylinder. When the work has been lightly clamped the treadle is further depressed, locking the fluid in the cylinder and tripping a clutch rotating the eccentric, thus applying the final pressure. Bodily movement of the cylinder by the eccentric is adjusted by rotation of the sleeve h and consequent variation of a gap above the plunger h<SP>2</SP>.

Title: Improvements in or relating to process of preparing derivatives of fluorocarbon acid, fluoride compounds and the derivatives resulting from said process
IPC: C25B3/28
Filed: 1949-07-07
Abstract: A process of preparing derivatives of fluorocarbon acid fluoride compounds comprises electrolysing a solution of liquid hydrogen fluoride containing a soluble hydrocarbon monocarboxylic acid wherein the hydrocarbon radical attached to the carboxyl group contains at least three carbon atoms, or the anhydride of such an acid, at a cell voltage insufficient to result in the formation of free fluorine but sufficient to cause the formation of one or more fluorocarbon acid fluoride compounds represented by the formula <FORM:0686678/IV (b)/1> where R is a saturated fluorocarbon radical containing at least three carbon atoms, and recovering the compounds and converting them to a derivative having the formula represented by R-Z, where Z is a monocarboxyl radical or a carbon-containing radical hydrolysable thereto.  The derivatives may be monocarboxylic acids and derivatives which upon hydrolysis yield the acids, for example, acid anhydrides, acid chlorides, acid bromides and acid iodides, amides, N-substituted amides, nitriles, esters and salts. The fluorocarbon acid fluorides react with water to form the corresponding fluorocarbon acids, from which fluorocarbon acid chlorides and bromides may be obtained by treatment with phosphorus pentachloride and tribromide, respectively. The acid iodides may be obtained from the chlorides and bromides by reaction with calcium iodide.  The fluorocarbon acid fluorides react with ammonia to form the corresponding amides.  The N-substituted amides can be prepared by condensation of the amines and the acid halides.  For example, the anilide and the parabromoanilide of n-heptafluorobutyric acid can be prepared by the reaction of aniline and of parabromoaniline respectively with n-heptafluorobutyryl fluoride.  The fluorocarbon nitrile may be obtained from the fluorocarbon amides by dehydration with phosphorus pentoxide. Fluorocarbon acid fluorides and chlorides may be caused to react with alcohols to form corresponding fluorocarbon esters.  Salts may be formed by reaction of the fluorocarbon acids with the elements and with the hydroxides, oxides and carbonates.  Examples are given of the production of: (a) undecafluorocyclohexylcarboxylic acid from the fluoride which was obtained electrolytically using hydrogen fluoride and benzoic acid; (b) the fully fluorinated cyclohexylacetamide C6F11CF2CONH2 from tri decafluorocyclohexyl acetyl fluoride obtained from starting material including phenylacetic acid; and (c) n-heptafluorobutyramide from the fluoride obtained with n-butyric acid as the organic starting material.
