Title: Manufacture of sulphonation products
IPC: C07B45/02
Filed: 1933-08-26
Abstract: Sulphonated products having wetting and emulsifying properties are obtained by treating tertiary alcohols containing at least one aliphatic residue having at least eight carbon atoms or a hydroaromatic residue with agents containing a sulphonating and dehydrating component.  As the sulphonating component, the usual sulphonating agents may be employed and as dehydrating components the following are mentioned: simple or mixed acid anhydrides of organic or inorganic acids, acid halides, pyro or meta acids and salts having a dehydrating action.  A mixture of acetic acid and sulphur trioxide may be used.  The tertiary alcohols may be treated first with the dehydrating component and later with the sulphonating agent, but a dehydrating component must be present during the sulphonating step. In examples, acetic anhydride and concentrated sulphuric acid are used to sulphonate: (1) undecyldiethylcarbinol, obtained from lauric ethylester and ethyl magnesium bromide; (2) octodecenyldimethyl carbinol, obtained from oleic ethyl ester and methyl magnesium bromide; (3) the carbinol obtained from soya oil and methyl magnesium bromide; and (4) the carbinol from carnauba wax and methylmagnesium bromide.  Tertiary carbinols derived from linseed oil, rape oil, olive oil, sperm oil, wood oil, wool fat, naphthenic and resin acids are mentioned. In working up the products, excess of acetic anhydride is removed by means of carbon tetrachloride or trichlorethylene and the sulphonate is extracted from the aqueous acid layer by means of butanol.  The extract or the aqueous solution of the products may be bleached by means of hydrogen peroxide.  The stability of the products in the presence of sulphuric acid, Epsom salt solution and mercerizing liquors is referred to.ALSO:Sulphonated products having emulsifying properties are obtained by treating tertiary alcohols containing at least one aliphatic residue having at least eight carbon atoms or a hydroaromatic residue with agents having a sulphonating and a dehydrating component.

IPC: G01L5/04
Filed: 1935-08-26
Abstract: 458,942. Indicating overload of cranes and ropes. CANALE, G. B., Villino Ceresa, Sori, Genoa, Italy. Aug. 26, 1935, No. 23837. [Classes 78 (ii), 78 (iv), and 78 (v)] [See also Group XIX] In a device for signalling and indicating the loading of cables, in which the rope is passed over fixed pulleys and under a movable pulley to form a loop which is diminished by the stress in the cable, pneumatic braking and cushioning means is fitted to absorb sudden violent shocks in the cables. In the form shown the movable pulley C moves a piston G against the action of springs E and also against the resistance of the dash-pot cylinder H controlled by the regulatable needle valve J. The piston rod carries an arm O moving over a scale Q to indicate its position, and also carries a contact which completes a circuit at R on overload and actuates an audible or visible signal. In modifications one contact is carried at the point F and the other on the cylinder, also two or more sets of contacts may be actuated in series at different stages of increasing load. In other cases, the cylinder may be movable and the piston fixed, or the cylinder may oscillate and the pulley C be connected thereto by a crank arm.

Title: Improved manufacture of tire covers for vehicles
IPC: B29D30/36
Filed: 1922-09-05
Abstract: 186,600. Hopkinson, E., and Hartford Rubber Works Co., (Assignees of Coe, J. P.). Sept. 24, 1921, [Convention date]. Moulding wheel tyres.-Tyre covers formed of rubber strands &c. built up into flat bands are shaped to the required contour by subjecting the bands to fluid pressure acting in direct contact therewith, the shape being retained by trapping the fluid under pressure therein, and subsequently vulcanising the tyre on the same rings on which it was shaped. The press comprises a cylindrical base 13 having an upper shell 12 on which slide abutments 10, 11 carrying the tyre beads. The lower abutment 11 is moved by plungers 14 operated by hydraulic pressure supplied through a circular pipe 16 the pressure being controlled by a valve 15. Movement of the upper abutment 10 is limited by arms 20 mounted on shafts 21, and adjustable by a hand wheel 29 through gearing 28, 25 and a chain 24. The pressure sealing device comprises a pair of annular members 30, 31 and an intermediate member 32, Fig. 4, the latter being mounted on a sleeve 33 of the lower member 31 and sleeve 33 is slotted to receive lugs 35 of a split ring 36 which locks the parts together. In operation the band is secured to the members 30, 31 in the position shown in Fig. 1 and the rams 14 are raised until the parts take up the position shown in Fig. 4. The air enclosed in the annular space 45 being thus compressed, forces the band outwards into the required shape. The enclosure 45 is rendered fluid tight by forming the members 30, 31, with bevelled faces 30<1>, 31<1> which fit into corresponding recesses in the member 32, by providing fluid tight gaskets 40, 41, 42, 43, and by mounting rubber strips 34 in channels in the members 32. The pressure inside the band may be reduced or increased bv means of a valve 47 and the air may be replaced by an inert fluid for the final curing by means of a valve 46. An alternative apparatus is shown in Fig. 6 in which the abutment members are replaced by solid platens 50, 51, and the corresponding sealing deviee comprises two head rings 61, 62, Fig. 8, an intermediate member 63, and a locking split ring 64. The rings have each a thrust face 67, a tapered face 68, and a cylindrical face 69 so as to obtain a fluid tight engagement, and have recesses 65 and humps 70 to secure and position the heads. The members 61, 62 are locked in their final position by inclined surfaces 72 engaging lips 64<1> of the locking ring 64. A modification of the rocking device is shown in Fig. 11 and comprises three parts 80, 81, 82 locked by a split ring 83 which is expanded from a groove 84 into a groove 85 by means of a cam 86, Fig. 12, having curved arms 87 which engage opposite ends of the split ring. A further modification is shown in Fig. 14 and comprises an intermediate member 100, flanking bands 101, and outer rings 102. Each band 101 is of duplicate construction and is provided with saw cuts 103 which allow the band to yield sufficiently so as to pass the shoulders 104 of the members 100.

Filed: 1959-07-16
Abstract: Organic substances (having a molecular weight less than 20,000 and chosen from fatty acids, petroleum fractions, essential oils and tar fractions) are stabilized against deterioration due to the presence of oxygen by admixing therewith 0,001 - 5% by weight of a 5-arylamino acenaphthene or a substitution derivative thereof wherein the substituents are non-ionogenic.  Examples Examples of such substituents are alkyl, cyclo-alkyl, aralkyl, phenyl, chlorophenyl trifluoromethyl, alkyl sulphonyl, benzyl sulphonyl phenyl sulphonyl, sulphonic acid dicyclohexylamide, sulphonic acid-N-phenyl-N-alkylamide, sulphonic acid piperidide, sulphonic acid ester, carboxylic acid ester, carbonic acid amide, alkoxy, benzyloxy, phenoxy or cyano groups or halogen atoms.  Petroleum fractions which may be stabilized include gasoline, lubricating oil, mineral oils and waxes.  In examples, lubricating oil, to which bis-salicylal-1,2-propylene diamine has been added as metal deactivator, is stabilized by the addition of 5-phenylaminoacenaphthene, 5-p-tert. butylphenylaminoacenaphthene, 5-p-hydroxylphenylaminoacenaphthene, 5 - p - methoxyphenylaminoacenaphthene, 5, 51-diacenaphthylamine or 5,51-diacenaphthyl benzidine.
