Title: Decorticating machine and process
IPC: D01B1/10
Filed: 1959-05-08
Abstract: 871,850. Decorticating pineapple leaves, sisal &c. ALMASSY, E., and ARENSON, D. Y. May 8, 1959 [June 11, 1958; Oct. 9, 1958; March 18, 1959], No. 15810/59. Class 120(1) Fibre-containing leaves are subjected first to pressure and then to friction and pressure applied to both sides of the leaves by passing the leaves between two hard and smooth surfaces while the surfaces move relatively to one another. The spacing between the surfaces is small in comparison with the normal cross-section of the leaves. Leaves are passed tips first and preferably concave side down between upper and lower conveyers 19, 20 and feed rollers 15, 16 (roller 16 being fluted) to decorticating rollers 13, 14 which are smooth cast iron cylinders: The lower roller 14 preferably rotates twice as fast as the upper roller 13 although the speed ratios are in the range 1:1À5 to 1:3À5. Scrapers 28, 29 which may be made of rubber bear against the rollers 13, 14. The latter are mounted in ball bearings mounted in eccentric bushes for adjustment of the position of the rollers. The feed rollers 15, 16 are adjustable relative to rollers 13, 14 and rotate more slowly. In order that the machine may be suitable for field work it is appropriately dimensioned and detachable units are provided for feeding the leaves and conveying away the fibres. The detachable feed unit may include one or more pairs of crushing rollers. A trough or the like may be provided to collect the juice of the decorticated leaves.

The contacts each have a tubular portion, such as 196, around which the sleeve 170 is disposed and provided with a T-shaped slot into which a tongue 172 on the sleeve 170 projects to locate the sleeve on the contact. In the case of the socket contact, this tongue resiliently engages the co-operating pin 150, when inserted, such pin being formed integral with and forwardly of its associated tubular portion. Rearwardly of the respective tubular portions, the contacts are crimped to conductors such as 166, 186. The housings may be attached to panels 142 by studs 138 integral with guiding and orienting members 132 . . . 135. A contact may be removed from its housing by inserting a cylindrical tool into the mouth of the associated bore so as to retract the tongue 174 and disengage it from the shoulder 158 whereupon the contact can be withdrawn rearwardly of the housing.

Title: Improvements in the production of carboxylic acid esters
Inventor: KROEPER HUGO
IPC: C07C51/10
Filed: 1958-05-20
Abstract: The invention comprises a process for the preparation of m-phthalic acid and terephthalic acid esters by reacting a dihalogen benzene, a mono halogenated benzoic acid or a mono-halogenated benzoic acid ester with an alkali alcoholate, in an anhydrous medium in the presence of carbon monoxide at elevated temperature and increased pressure.  Starting materials specified are m- and p-dibrombenzene, m- and p-dichlorobenzene and m- and p-chlorobenzoic acid or its esters.  The alcoholates of sodium or potassium are preferably employed, especially those derived from e.g. methanol, ethanol, or propanol.  The reactants may be present in stoichiometrical proportions, or either of the two reactants may be present in slight excess, e.g. up to 0.1 mol.  Solvents such as benzene, gasoline or the alcohol corresponding to the alcoholate, may be used, provided that they are anhydrous.  A catalyst such as metal carbonyls, e.g. the carbonyls of nickel, cobalt, iron, molybdenum, chromium, or metal carbonyl hydrides, e.g. cobalt carbonyl hydride or complex metal carbonyl compounds such as Fe(CO)4Br2, R3P2N1(CO)2 or R3PN1(CO3), where R represents a hydrocarbon radical, e.g. alkyl or aryl.  The metal carbonyl compounds may be added as such or formed from their components during the reaction, e.g. by adding the carbonyl forming metals in a fine dispersion to the reaction mixture.  It is preferable to use those compounds of carbonyl-forming metals which are soluble in the reaction medium, e.g. the acetates, formates, acetylacetonates, acetylacetates of nickel.  The metals may be added to the initial materials in amounts of 0.1 to 3% by weight, with reference to the content of carbonyl-forming metal.  The reaction may be carried out at 100-400 DEG  C. at 5-700 atmospheres of carbon monoxide, and may be batchwise or continuous.  If the necessary pressure for the reaction cannot be set up by heat alone in a closed vessel, further carbon monoxide or an inert gas such as nitrogen may be forced into the apparatus.  Examples are given of the preparation of dimethyl terephthalate, together with some free terephthalic acid as a by-product, from p-dichlorbenzene and sodium methylate.

Title: Process for the desulphurization of ferrous melt
IPC: C21C7/064
Filed: 1958-05-20
Abstract: Ferrous melts are de-sulphurized by the injection of comminuted calcium carbide in a stream of carrier gas followed by the injection of a gas free from calcium carbide.  The gas free from calcium carbide may be the carrier gas used in the first stage. Calcium carbide having a particle size of 14 x 200 mesh may be used and the carrier gas may be nitrogen, argon, helium, hydrogen, or natural gas. A ladle of 500 lb. was blown for 1 to 2 minutes at a flow rate of 400 cubic ft. per hour during which 25 lb. of calcium carbide was added. With an after blow of 1 minute the sulphur content was reduced to 0.004%.

Title: Improvements in frequency changers
IPC: H03B19/03
Filed: 1922-06-12
Abstract: 184,150. Ges. f³r Drahtlose Telegraphie. Aug. 2, 1921, [Convention date]. Void [Published under Sect. 91 of the Act]. Frequency, changing.-In an arrangement for changing the frequency of electric oscillations by means of iron-cored choking-coils or transformers, the phase difference between current and voltage is made as large as possible in the circuit of the frequency-changer T and as small as possible in the circuit of the generator G, the two circuits being so coupled together that these phase differences exist simultaneously. In the arrangement shown, the frequency-changer T is connected across a condenser C through an inductance L<2> which is adjusted to give a phase difference of nearly 90‹ between the current and voltage in the changer. The condenser is connected to the high-frequency generator G through a circuit tuned to give little or no phase difference between current and voltage. To obtain an n-fold increase of frequency, where n is odd, the iron core must be saturated in a time equal to or less than the 4 nth part of the fundamental period. Directcurrent magnetization is necessary in order to obtain an even n-fold increase, and it may be employed in obtaining an odd multiplication. Signalling or telephone control may be effected by varying the direct current. An inductive coupling between the generator and transformer circuits may be employed instead of the condenser C.

Abstract: 534,727. Hydraulic clutches. SALERNI, P. M. June 7, 1939, Nos. 16733/39 and 11256/40. [Class 69 (ii)] A hydraulic power transmitter comprises impeller vanes 1 connected to a driving shaft 2, turbine blades 3a, 3b connected to a driven shaft 4, and a reaction member 5a, 5b which is capable of rotation in either direction but'is prevented by automatic braking from rotating backwards at too high a speed. The drum 6 which carries the reaction member has friction rings 7 keyed to it and capable of engaging similar rings 8 keyed on a loose sleeve 9 loaded by a spring, and having teeth 9a adapted to engage teeth 12a on a nut 12. Centrifugal weights 18 forming a split ring are pressed by springs against plates keyed to the drum and enclosing a plate keyed to the nut and at low speeds tend to press the clutch rings 7, 8 together, while at high speeds the weights are forced away from the plates by their engagement with inclined surfaces 20 on the drum. It is stated that at the lowest backward rotational speeds, the friction is insufficient to move the nut into locking position. In a modification, the centrifugal weights and friction plates are dispensed with, oil drag being relied on to rotate the nut at high speeds. Specification 520,224 is referred to.
