Title: Improvements in or relating to the manufacture of cigarettes
IPC: A24C5/47
Filed: 1933-05-10
Abstract: 419,364. Cigarette-making machines. WIX, A., 338, Goswell Road, and EDWARDS, W. F. M., 1, Kempsford Gardens, Earl's Court, both in London. May 10, 1933, No. 13563. [Class 130.] In the manufacture of cigarettes with inserted mouth. pieces or filter tips the cigarettes oi cigarette paper tubes are carried by an intermittently rotating drum or carrier to a position in which the mouthpiece insertion devices are operative. The cigarettes or the paper tubes are fed from a hopper to a chamber in which each cigarette or tube is retained by stops until a receiving chamber in the intermittently rotatable drum or element is positioned opposite the outlet of the chamber, when the stops are moved out of the path of the cigarette or tube before it is ejected into a chamber in the drum by a reciprocating slide. In the construction shown in Fig. 1, the cigarettes, which are fed singly from a hopper 11 to a grooved drum 12, are retained in the drum by guides 13b and are afterwards positively discharged by guides, extending into grooves in the drum, into a shoot or feed chamber 13. To prevent the cigarettes jamming where the drum 12 leaves the hopper 11, a roller 11<a> is rotated in the same direction as the drum. The outlet 13<a> of the shoot 13 is obstructed by stops 14, carried on pivoted arms 14<a>, and pins 15<a> on a reciprocating slide 15 lower the arms 14<a> against the action of a spring 14b before the slide forces the cigarette into a channel 10<b> in the drum 60. The cigarette is held in the drum by the slide until it is engaged in a tubular bore at the end of the channel. The drum is then reciprocated into alignment with operating devices which remove tobacco from the mouthpiece end of a cigarette, insert a filter tip, and discharge the tipped cigarette. If a cigarette carried by the drum receives a filter tip from a reciprocating spoon 30, Fig. 3, a plunger 31 is moved back by its engagement with the tip, against the action of a spring 31<a> until a block 32 on the plunger engages a flanged head on a reciprocating locking plunger 33 which holds the plunger 31 against further rearward movement and ejects the cigarette as the drum approaches the plunger 31. If the mouthpiece end of the cigarette is empty, the commencement of the rearward movement is delayed until the reciprocation of the plunger 33 has been completed and the block 32 is unable to contact with the plunger 33, so that the plunger 31 moves back freely against the spring 31<a> and leaves the cigarette in the drum as it rotates towards the feeding mechanism. To prevent a cigarette entering a channel in the drum containing a cigarette without a tip, a feeler lever 35, Fig. 1, which is mounted in advance of the feeding position contacts with the cigarette and releases a trip lever 23 from an inoperative position to trip the feeding mechanism without stopping the drum. The discharged cigarettes are received in a recess 37<a> in a roller 37 and are delivered on to a chute 38 leading to a conveyer belts 39.

Patent GB-792487-A (GB)
Title: Recovery of water-soluble aliphatic dicarboxylic acid
IPC: C07C51/48
Filed: 1956-05-03
Abstract: Water-soluble aliphatic dicarboxylic acids are recovered from their solution in aqueous nitric acid by extracting the solution with an organic solvent for the dicarboxylic acids which is substantially immiscible with the nitric acid, freeing the resulting extract from nitric acid by washing it with water, and recovering the dibasic acid from the extract by washing with a further quantity of water.  The invention is of particular value for the recovery of dicarboxylic acids resulting from the nitric acid oxidation of long chain, e.g. C10-24, especially C16-24, unsaturated fatty acids, but may be used generally for the recovery of aliphatic dicarboxylic acids from their solutions in aqueous nitric acid having a nitric acid concentration between about 5-40 per cent by weight based on the combined weight of the nitric acid and water.  The oily layer is separated from the oxidation product and, if desired, washed with hot water which is added to the aqueous layer.  Suitable solvents for extracting the acids from the aqueous nitric acid include mixtures of normal paraffins with aliphatic esters or ethers in which neither of the aliphatic radicals contains more than 5 carbon atoms.  Specific mixtures mentioned are n-heptane with butyl acetate, propyl butyrate or di-n-propyl ether and n-hexane with butyl propionate or n-propyl n-butyl ether.  Preferred temperatures for extraction are about 0-50 DEG  C. although when the extractant contains an ether it is preferred to keep the temperature below about 25 DEG  C. and also the concentration of nitric acid below about 25 per cent by weight.  In continuous operation about 2-8 volumes of extractant for each volume of the aqueous solution are generally used; for batchwise operation less may be used, e.g. equal volumes of extractant and solution.  The extract is freed from nitric acid by washing with 1/10 -2 volumes of water, preferably at 0-50 DEG  C., and then preferably concentrated by distilling off solvent until the concentration of dibasic acid is at least 5 per cent and preferably 5-10 per cent by weight.  It is then extracted with water, suitably 1-3 volumes, possibly at 20-80 DEG  C., although higher or lower temperatures may be used.  The dibasic acid may be recovered from the resulting aqueous solution in any desired manner, e.g. by concentrating and then cooling.  In an example, oleic acid is oxidized with nitric acid, the aqueous layer extracted with a n-heptane/n-butylacetate mixture, the organic layer washed twice with 1/5 its volume of water at 25 DEG  C., evaporated to 1/4 of its original volume and extracted with twice its volume of water at 65 DEG  C.; the water extract is concentrated to 1/5 of its original volume and cooled, whereupon the dibasic acid crystallizes out.

Title: Production of amines
Inventor: KOEBNER ADOLF
IPC: C07C215/08
Filed: 1963-04-08
Abstract: Amines are prepared by heating ammonia or an amino compound of the formula RNH2 (where R is a substituted or unsubstituted hydrocarbyl group) with a mono-sulphate ester of the formula R1OSO3M (where R1 is derived from the alcohol R1OH having at least 6 carbon atoms and M is a cation) in an alkaline aqueous reaction medium wherein the monosulphate ester is soluble and which comprises a solution of at least 25% by weight, based on the weight of water, of (a) one or more salts of aromatic sulphonic acids in which the aromatic nucleus contains no alkyl substituent having more than 4 carbon atoms or (b), when ammonia is employed as reactant, of urea; and isolating the resultant amine of the formula R1NH2 or RR1NH.  Ammonia may be employed in the form of an aqueous solution or as a gas and the mono-sulphate ester reactants may be polyoxyalkylene ether sulphates. The aqueous alkaline solution remaining after extraction of the amine therefrom by, for example, treatment with caustic alkali may be treated with dilute sulphuric acid to reduce the pH to 7.0 to 8.0, the substantially neutral solution so obtained filtered and the filtrate concentrated for recycle to the amine preparation step.

Title: Improvements in "stars" for the introduction and withdrawal of bottles, for machinesfor filling, corking, capsuling and labelling bottles
IPC: B67C7/00
Filed: 1932-05-14
Abstract: 381,128. Feeding bottles to machines. DETREZ, R., 39, Rue St.-Quentin, Nogentsur-Marne, France. May 14, 1932, No. 13899. Convention date, July 8, 1931. [Class 117.] In machines for filling, corking, &c. bottles, of the type having stars for feeding bottles to and delivering them from the machine, the star 3 has, underneath its surface and concentric with its centre, a number of teeth 6, meshing with a similar number of teeth on the periphery of a flange on the top of the driving spindle 5, the number of teeth on each being large in relation to the number of branches of the star. The number of teeth on the star (or flange) and the number of cells of the star are prime numbers, so that a form of differential adjustment of the star in relation to its spindle is obtained. The distance to which the star can be adjusted is, therefore, the length of the circumference of the star divided by the product of the number of teeth on the star (or the spindle) with the number of cells or branches of the star (as shown, five). A screw 7, screwing into the spindle 5, tightens the removable washer 8 on to the star 3. The head of this screw is of slightly smaller diameter than that of the central hole in the star 3, facilitating removal of the star. An aperture 9 is provided in the star, to mark coinciding teeth thus facilitating refitting after disassembling.

Title: Improvements in or relating to stroboscopes
IPC: H05B41/34
Filed: 1945-06-02
Abstract: 593,593. Stroboscopic apparatus. MAYER, V. June 2, 1945, No. 13916. [Class 97 (i)] In stroboscopes of the type having a shutter for intermittently viewing or illuminating a rotating body and oscillated by an electric motor at a frequency governed by that of a spring and varied by holding the spring at different points, the spring comprises a length of wire having a spiral coil at one end anchored to the shutter and at the other end having a helical coil anchored to a fixed member. The box-like shutter 5 having two or more sets of opposed slits is carried on an armature 4c moving within an electromagnet 4b and connected to one end of a spiral spring 8, the other end 8a of which is connected by a helical spring 8b to the casing. The natural frequency of the spring is varied by engagement with a slide 16 movable along the casing and co-operating with a scale. In operation, the magnet is energized to rotate the armature which thereupon breaks the magnet circuit and returns under the action of the spring when the circuit is again completed and the movement repeated. The switch comprises a metal strip 9, Fig. 6, connected by a coiled spring to a pin 10 and having an upper arm 9a engaged by a pivoted lever 14. A pin 12 on the shaft on the armature engages the other arm 13 of the lever when returned by the spring 8, the lever 14 thereby rotating the spring 9 to make a contact 9e thereon engage a fixed contact 15 to complete the magnet circuit which rotates the armature, disengages the pin 12 from the arm 13 and breaks the circuit. The contact 15 is on a pivoted lever 20 moved simultaneously with the slide 16 to ensure the same amplitude of oscillation at all frequencies. A lamp 24 may be used for illumination.
