Title: Improvements relating to the production of sulphonic acids
Inventor: MARRIAN STANLEY FREDERIC
IPC: C07C303/14
Filed: 1964-05-27
Abstract: Sulphonic acids are prepared by reacting a paraffin containing at least 8 carbon atoms with sulphur dioxide and oxygen in a sulphoxidation reaction carried out in the presence of an organic solvent for the sulphonic acid which is substantially inert to the sulphoxidation conditions and separating a solvent/hydrocarbon phase containing most of the sulphonic acid from a sulphuric acid phase. The reaction may be initiated by irradiation, by the presence of a heavy salt of an organic acid or by the use of an organic acid. Preferred organic solvents include polyhalogenated C1- 3 hydrocarbons which preferably contain one or two carbon atoms and at least two chlorine atoms.  A preferred aliphatic hydrocarbon starting material is a C10- 13 normal paraffin feedstock.  The products may be used as detergent sulphonates having a low level of sulphate by neutralization of the acids in the solvent/hydrocarbon layer either before or after extraction with water.

Title: Improvement in universal agricultural implements
IPC: A01B35/10
Filed: 1923-08-31
Abstract: 204,314. Moline flow Co. Inc., (Assignees of Boda, J. E.). Sept. 25, 1922, [Convention date]. Multiple-tool and disc-tool implements; adjusting and lifting parts; tools; draught devices. - A universal implement to which ploughs, harrows, and other agricultural tools may be attached, comprises a transversely arranged tool-carrying bar, two supporting-wheels on separate cranked axles, means for adjusting each wheel separately, self-lift mechanism to rotate each axle through a different angle of rotation, but so as to raise the tools to substantially the same height above the ground, and means for connecting the tool-bar to a tractor or draught device. The cranked axles are mounted in brackets 15 on the rectangular tool-bar 3 which is arranged so that two of its edges lie in a vertical plane passing through its axis.. The standards 8 of the ploughs or other tools are clamped on the bar by clamps 20, parts of which are rigidly attached to the standards 8. Converging and braced bars 31 are clamped to the tool-bar 3 at their rear ends and bent downwards and perforated at their forward ends to receive the pivot pins of two converging draught bars 35 adapted to be connected to the tractor draw-bar 40. The bars 35 are adjust ably connected to the cross-brace of the bars 31 by a link 41, chain 42, and slotted catch plate 44. This connection is slack while the implement is at work, but becomes taut and prevents the implement from tipping backwards when the tool-bar is lifted. By reducing the effective length of the chain the rear end of the implement may be held up high for inspection of the shares &c. Power mechanism for raising the tool-bar comprises a clutch driven from one of the wheels and thrown into action by a trip level 50 and a cord or chain 51. The clutch operates a crank 52, Fig. 5, connected to the draught frame bv links 53, 54. The depth of work is regulated by a lever 6 connected to the links 53, 54 by a link 56. To allow of the furrow wheel being at a different level from the land wheel its axle 13, Fig. 17, is free to turn in a sleeve 14 keyed on the land-wheel axle 12, the movement being normally limited by stops 60, 61. The movement may be stopped at any point by means of a lever 7 connected to an arm 62 on the axle 13 by a slotted link 63. The tools may consist of double or single mouldboard ploughs, rotary discs, drag harrows, &c. and several different kinds may be mounted on the one tool-bar. The tools may be adjusted along the bar and arranged for vineyard or orchard ploughing &c. Specifications 193,011 and 193,022 are referred to.

Filed: 1919-09-11
Abstract: 151,810. Electric Construction Co., and Tonkinson, W. Sept. 11, 1919. Systems depending on the use of two or more machines.-A synchronous rotary converter or other synchronous machine A is started up by means of an induction motor D having one or more pairs of poles less than the machine A, and the rotor E of the motor is connected to an auxiliary armature F rotating within a magnet yoke G, the auxiliary armature and magnet yoke having a number of poles equal to the difference between the number of poles of the motor D and machine A. The armature F is mounted on the same shaft C as the rotor D and armature B of the machine A, or on a shaft coupled to the shaft C. The motor D is started by closing switches J, L, the magnet yoke G being excited from the continuous-current side of the converter soon after the set begins to speed up. The motor D tends to run at a speed above the synchronous speed, but this tendency is overcome by the counter electromotive force generated in the armature F. When the set reaches the synchronous speed, the main switch H is closed and the switches J, L are opened, leaving the motor D and auxiliary armature running light. If desired, a clutch may be provided to allow the motor and auxiliary armature to be disconnected from the converter after starting up. Resistances h may be provided to check the initial rush of current in the starting-motor.

A rod 26 fixed to each member 12 and sliding in a collar 25 connected by links 27, 28 to levers 10, 11 keeps the member 12 horizontal. Arm 39 incorporates a cylinder 40 having a piston 41, Fig. 5, and being connected to a bellows 44 mounted on part 45 of base 2. Bellows 44 act on a lever 46 pivoted at 47 and controlling a valve 52 which controls the flow of pressurized fluid to cylinder 18. Should the height of element 15 above the intermediate support decrease below a certain value causing lever 37 to rotate, then piston 41 and bellows 44 cause valve 52 to retract the piston rod 20 to lower the collector until the contact pressure with the conductor wire returns to a predetermined value. Similarly when the height of element 15 rises above a certain value, the valve 52 is operated to cause rod 20 to raise the collector. A bellows 50 controlled manually from lever 62 and pump 63 can control valve 52 to lower the main structure as desired. The hydraulic system may be replaced by an equivalent electrical system and the torsion rod 36 biasing the subsidiary structure upwards may be replaced by an adjustable hydraulic mechanism.

Title: Improvements in or relating to threshing mechanism
Inventor: HERBSTHOFER FRANZ
IPC: A01F12/18
Filed: 1964-06-04
Abstract: An axial-flow threshing and separating apparatus comprises two co-axial frustoconical assemblies intercommunicating, the first assembly consisting of a threshing drum 40 and concave 44 and the second, of larger diameter, comprising a separating drum 41 and a sieve 29.  The concave forms only the lower part of the member 28 surrounding the threshing drum the remainder comprising an annular sieve 55.  The concave is adjustable relatively to the threshing drum and there is normally a smaller clearance between the drum and concave than between the drum and annular sieve. The beater bars 50 are of part-cylindrical cross-section and have transverse serrations 52 tending to propel the straw towards the wider end of the drum. The separating drums comprises bars 60 of triangular section arranged helically.  The sieve 29 surrounding the separating drums is similar to that above the threshing cylinder.  The bars 60 of the separating drum are continuous with the bars 71 of a third section 42, these bars 71, however, being arranged cylindrically within a section 30 of the casing.  This section comprises a lower arcuate sieve 66 and an upper imperforate portion 69 which contains an opening communicating with a straw-discharge shoot 70.  The grain, chobs, and chaff falling through the concave and sieves pass through conventional shakers subjected to a winnowing air-blast, the grain being finally fed into a grain tank and chobs being re-fed to the threshing drum.  The crop is initially fed into the threshing drum through an aperture in the wall of the section 28.
