Patent GB-813842-A (GB)
Title: Improvements in or relating to the production of aliphatic mono-and di-carboxylic acids
IPC: C07C51/27
Filed: 1956-02-07
Abstract: Saturated mono- and di-carboxylic acids are prepared by oxidizing ethylenically unsaturated fatty acids containing at least 12 carbon atoms in a first stage by means of molecular oxygen to produce saturated mono- and di-carboxylic acids, terminating this stage while further oxidation is still possible and effecting further oxidation in a second stage with nitric acid, substantial oxidation taking place in both stages and the second stage being continued to achieve a substantial increase in yield of saturated mono-and di-carboxylic acids.  The first stage may be carried out by passing air or other gas containing free oxygen, preferably under pressure, through a solution of the unsaturated fatty acid in a solvent such as acetic acid, benzene, propanol or an ester.  An oxidation catalyst such as one containing Co, Mn, Cu or Cr, for example, cobalt acetate or naphthenate, may be present; alternatively, or in addition, an oxidation promotor, e.g. acetaldehyde, may be used.  This oxidation may be effected at about 25-150 DEG  C., preferably below 90 DEG  C. It is preferably terminated when the unsaturation of the initial acid is reduced by 70-100 per cent, the oxidation products then comprising substantial amounts of mono- and di-carboxylic acids.  The second stage may be effected by slowly adding the crude mixture from the first stage, freed from solvent, to nitric acid, preferably of 40-85 per cent strength and at 30-35 DEG  C., followed by heating to about 100 DEG  C.  Nitric oxide formed may be re-oxidized with air to nitric acid either in situ or separately and reused.  The final product forms an upper non-aqueous layer containing monocarboxylic acids and a lower aqueous layer of nitric acid and dicarboxylic acids.  The lower layer may be chilled to crystallize the dicarboxylic acids. Preferably, the aqueous layer is extracted with, for example, cyclohexane or n-heptane to remove monocarboxylic acids; the extract and the upper non-aqueous layer are combined, extracted with water and then fractionated to recover monocarboxylic acids. The aqueous layer and the aqueous extract are combined and cooled to recover the dicarboxylic acids.  In examples: (1) crude oleic acid in admixture with acetic acid, acetaldehyde and cobalt acetate is air oxidized at 65 p.s.i.g. at 54 DEG  C. to reduce the unsaturation by about 96 per cent, the acetic acid is stripped off and the residue further oxidized with nitric acid and the products are worked up to recover pelargonic acid and C6-C9 dicarboxylic acids, mainly azelaic and suberic acids; small amounts of esters are also formed; (2) a mixture of oleic, linoleic and saturated acids from tall oil is similarly oxidized, yielding pelargonic acid, caproic acid and C6-C9 dicarboxylic acids; (3) as in (2) omitting the acetaldehyde; (4) crude tall oil is oxidized as in (1).  Other unsaturated fatty acids mentioned are palmitoleic, petroselenic, linolenic and erucic acids acids and foots oil.

Title: Improvements in or relating to the Drying of Vegetables, Fruits and other Objects of Manufactured Products.
Inventor: SAVY EMILE LOUIS ALFRED
IPC: F26B25/00
Filed: 1919-02-18
Abstract: 123,981. Savy, E. L. A. March 8, 1918, [Convention date]. Cooking-stoces.-Fruit, vegetables, and other products or manufactured articles are dried by vanes rotating horizontally above the material &c. which is enclosed between horizontal permeable walls; the air may work in a closed, open, or semiclosed circuit. When working in a closed circuit, cooking is stated to be effected. In the apparatus shown in Fig. 1, the material is contained in drawers 3 capable of sliding in U-irons 4. These drawers have perforated bottoms and the angle irons support sliding frames covered with perforated material 10<1>, Fig. 3. above the drawers; alternatively, the drawers themselves may be covered with perforated material. Vertical shafts G carrying vanes 5 and driven through bevel gearing are placed between the adjacent tiers of drawers. Air enters through a passage 16 controlled by a damper 23 and is circulated by a fan 12 through a steam heating-column 11, through the drying chamber and out through apertures 18 at the bottom into a passage 15. Dampers 21, 22 in this passage control the flow of air either back to the fan 12 to circulate again through the drying chamber, or to a fan 19 which ejects it to atmosphere. Feeding and discharging may be effected by means of trucks 24, 24<1>, Fig. 4, having slides 25 supporting the drawers; the entry of a drawer of fresh material effects the discharge of a drawer of dried material. Figs. 6 and 9 show similar apparatus, wherein vanes n rotate between the surfaces of endless brattices on to which the material is fed bv a cutting device b. The upper surface of each brattice rests on the lower surface h<1>, Fig. 11, of an angle iron, and the lower surface on the upper surface of the next lower iron. The material is thus enclosed be tween the upper surface of one conveyer and the lower surface of the next, the angle-irons shutting the sides off. A fan t, Fig. 6. draws air from the drier through a dampered passage v, and from the atmosphere through a shuttered orifice, and forces it over heating-coils x<1> into 'the drier, whence it escapes through apertures at the top and dampered passages r<1>, Fig. 9, to a fan r<11>, Fig. 6. By variously manipulating the dampers, the air circulation may be made open, closed, or semi-closed.

Title: Improvements in or relating to machine for making articles such as bags from multiple thermoplastic webs
IPC: B31B23/00
Filed: 1959-02-05
Abstract: 905,263. Feeding webs. SCHJELDAHL CO., G. T. Feb. 5, 1959 [Oct. 8, 1958], No. 4143/59. Class 100 (1). [Also in Groups VIII, XVII and XXIV] Apparatus for feeding webs in, for example, a bag-making machine, comprises driving means for each web which is independently controllable so that the speed of feeding one web may be varied relative to that of another. As described, a pair of longitudinally folded webs are fed intermittently side by side and lying in a common plane by rollers on shafts 67, 76 to transverse sealing and severing means 98, 115 to produce two bags per machine cycle. The driving roller on shaft 67 consists of two halves 68, 69, one per web, and each driven by identical mechanisms 10 which are as described in Specification 871,018 [Group XXIV]. The speed of each web is adjusted by varying the crank throw of the mechanisms. Both mechanisms are operated by a common shaft 26 driven by a continuously running motor 16. The pressure roller on the shaft 76 is in two freely rotatable halves 74, 75 and both driving roller sets are covered with friction material slotted at 70. Guide fingers 71 extend through the slots. A guide roll 88 may be raised and lowered by hand-operated screw means (Fig. 2, not shown). Each web is scanned by photo-electric means (Fig. 6, not shown), responsive to printing and operative to vary the drive periods of the roller halves through the clutches 49, 50 of the mechanisms 10. The desired positions of severance are thus presented to the common sealing and severing bar 115 which is lowered by hydraulic means 130, 133, 134 and linkage 122, 127 at each end to rest on a backing roll 98 (Fig. 5). Initial positioning of the cutting and sealing lines is achieved by varying the height of the roll 88, which comprises independent sections, one for each web, to obtain an average displacement and then individually adjusting the photo-electric eyes. Alternatively, the sections of the roll 88 may be independently adjustable. The apparatus is wholly automatic and controlled by cam-operated switch means (Fig. 6, not shown). Rollers on the shaft 76 and the bar 115 may be raised clear of the webs by hand-operated eccentrics 81, 118.

Filed: 1922-02-15
Abstract: 188,603. Metropolitan - Vickers Electrical Co., Ltd., (Westinghouse Electric & Manufacturing Co.). Feb. 15, 1922. Regulation, automatic systems and apparatus for.-In systems for maintaining constant but adjustable speed-ratio between several electric motors. for example in the working of paper-making machinery, automatic regulation of motorfield resistance 9 is effected by periodic shortcircuiting under the combined action of two rotary interrupters 45, 53 connected in series. The interrupter 45 is revolved by friction-wheel gearing or other variable ratio gearing from the motor 2, and the interrupter 53 is revolved by a standard-speed synchronous motor 31 fed from a motor generator set 43 which is regulated as required to vary the standard speed. The average effective value of the resistance 9 is altered when the speed cf the interrupter 45 departs from the standard, the resulting change of field strength acting to restore it automatically. Each of the rotary interrupters shown in developed form in Fig. 5, comprises two insulating semi-circular segments superposed alternately upon two similar conducting segments, and brushes 180‹ apart. In order to improve the steadiness of the regulation, the resistance may be divided into sections and controlled by additional commutators and brushes. The segments of each commutator may also be reduced in size and increased in number.
