Title: Improvements in or relating to combine harvesters
IPC: A01D75/28
Filed: 1961-05-16
Abstract: 905,023. Combine harvesters. CLAAS, W. May 16, 1961 [May 17, 1960], No. 17890/61. Class 6(3). In a combine-harvester, of the kind wherein guide members, such as 15, influence the passage of the straw over the shaker 11 according to the inclination of the machine to the horizontal, the guide-members 15 are movable against the straw to prevent undue accumulation thereof at one end or on one side of the shaker. As shown, the members 15 each comprise a grid secured to a spindle 14 which is cranked, externally of the harvester-body 10 and connected by an adjustable link 18 to a pendulum 19 pivoted on a bracket 21. The connection 22 is adjustable along the crank 17 so that the pendulum 19 is sensitive to longitudinal tilt only or to both lateral and longitudinal tilt, Fig. 3 (not shown). Modifications are mentioned in which the spindles 14 are driven by electric motors controlled by mercury switches, and in which a plurality of members 15 are arranged along each side of the shaker. The guides may, alternatively, be mounted on parallelogram linkwork.

Title: Improvements in the production of polymers
Inventor: CRAWFORD JOHN WILLIAM CROOM
IPC: C08F32/00
Filed: 1956-06-11
Abstract: Crystalline polystyrene and copolymers of styrene with other olefins are made by polymerizing styrene having a soluble copper compound dissolved therein, alone or in admixture with another olefin in the presence of a medium containing a catalyst formed by reacting a hydrocarbon compound of aluminium, gallium, indium, thallium, or lead, with a tetravalent vanadium compound in a proportion of vanadium compound to hydrocarbon compound on a molar basis of less than 1.2 to 1.  The polymers may be purified by treatment with an hydroxyl containing compound, e.g. water or steam, to decompose the catalytic material, adding an hydrocarbon solvent, and washing the mix with an alcohol containing mineral acid to remove the decomposed material.  The preferred medium is an hydrocarbon solvent such as methyl cyclohexane.  Suitable styrene soluble copper compounds are copper naphthenate, copper propionylacetonate, and copper hexoylacetonate.  The vanadium compound may be vanadium tetrachloride and the hydrocarbon compound aluminium triethyl.  Other olefines mentioned are ethylene, propylene, butene-1, butene-2, vinyl toluene, vinyl naphthalene, allyl benzene, 1 - vinylcyclohex - 3 - ene, butadiene and isoprene.  The polymerization reaction is conducted at a temperature within the range -30 DEG  to 70 DEG  C.  Specification 808,132 is referred to.

Abstract: 432,462. Remote - controlled door fastenings and indicators. FAHRBACH, G., 44, Senefelderstrasse, Stuttgart, Germany. June 18, 1934, No. 17946. Convention date, June 19, 1933. [Classes 44 and 65 (i)] A door lock, which is electrically controlled from a distant position, is provided with an electric circuit which is closed, independently of the position of the bolt, when the door is opened and operates an audible or visible signal at the distant position until the door is again closed. When the door is closed, the various parts are positioned as shown in full lines, closure of a switch 2 or 2<1> energizes coils 4 to rock a bell-crank lever 8, 9 against a spring and to thereby free a spring-pressed pivoted member 10 and to allow the bolt 11 to rock about a vertical axis when the door is pushed to open it. Opening of the door moves a pivoted or springy member 12 away from an abutment 14 on the door post and allows the member 12 and, through a rack and pinion 15 or levers, a contact lever 6 to assume their dotted line positions, a spring acting on the lever 6. The contact at 5 in the lock controlling circuit is broken and a signalling circuit is completed by contact at 17, a signal 19 being operated until. the door is again closed or a separate switch is opened. The signal 19 which may be an electric lamp may be housed within a glass cover for the switch 2 of the push-in type. A lamp 20 may be provided in the lock-controlling circuit on the door to indicate when the lock is free, and the lock may be controlled from a number of distant positions.

Title: Arrangements for determining the moisture content of granular materials,more particularly moulding sand for foundries
IPC: G01N27/22
Filed: 1965-04-29
Abstract: 1,111,695. Measuring moisture content of materials electrically. MUSZERIPARI KUTATO INTEZET. April 29, 1965 [May 14, 1964], No.18124/65. Heading G1N. The moisture content of a moulding sand, for foundry work, is measured in a measuring cell (not shown) which has a mechanical means to compress the sand to a degree wherein the value of the filling factor corresponds to its required condition when moulding, and the sand in the cell forms the dielectric of a capacitor connected in a tuning circuit of an oscillator the magnitude of the direct current feed to which is taken as a measure of moisture content. In order to reduce the effect of the loss resistance due to moisture on the circuit Q and on the measurements, the cell is connected in the tuning circuit as shown in Fig. 1, where C m , R m  represent the capacitance and loss resistance of the cell and C 1 , R 1  represent the capacitance and loss resistance of a low loss standard capacitor, in series with the cell across an inductor L. The variation in capacitance of the cell in proportion to the moisture content results in a corresponding variation in the direct current supplied to the oscillator, which current is measured in an ammeter calibrated directly in percentage moisture content.

Title: Purification of acids
IPC: C07C51/487
Filed: 1953-07-02
Abstract: A fatty acid containing a plurality of carbon atoms and contaminated with formic acid is purified by heating the mixture with a fatty acid anhydride so that the anhydride reacts with the formic acid to produce carbon monoxide and the fatty acid corresponding to the anhydride.  Preferably the anhydride corresponding to the acid being purified is used.  The process may be operated with or without a catalyst.  The preferred catalysts are tertiary amines such as pyridine and triethyl amine and salts of inorganic bases with the fatty acid being purified. In the examples: (a) acetic acid contaminated with formic acid is heated and treated with acetic anhydride in the presence of pyridine to give substantially pure acetic acid, and (b) the process is carried out as in (a) using sodium acetate instead of pyridine as catalyst.
