Patent EP-0453604-A1 (EP)
Inventor: GLATZ BERND DR
IPC: G01N30/88
Filed: 1990-04-27
Abstract: The invention relates to a process for the chromatographic determination of ions, particularly anions on a reversed-phase column, in which sample ions are introduced into a mobile phase containing a modifier and a counterion, the mobile phase with the modifier, counterion and sample ions is passed through the column and, after separation with the aid of a suitable detection method, preferably an indirect UV-detection method, the individual sample ions are determined quantitatively via the decrease the counterion concentration in the eluate. In this process the mobile phase is a mixture of water and an organic solvent and has a pH-value of more than 5. The modifier used is a quaternary ammonium hydroxide of formula
       
 in which at least one radical is a straight-chained or branched alkyl radical with at least 8 and up to 20, more particularly 12 to 18 C-atoms. Prior to the passage of the mobile phase containing the sample ions, the reversed-phase column is preferably brought into equilibrium with the modifier, particularly with the modifier and the counterion. Trimethyl hexadecyl ammonium hydroxide is preferable used as the quaternary ammonium hydroxide. 
     The invention also relates to the use of said quaternary ammonium hydroxides for the quantitative chromatographic determination of ions and in particular for the determination of inorganic anions, as well as to a reversed-phase material chromatographic column obtained through the conditioning with the modifier.

Abstract: The invention relates to methods and devices for the manufacture of girderlike shaped bodies (15) from vegetable particles mixed with binders, in moulding presses. Starting from the knowledge that the core of such shaped bodies (15) is compressed less, the greater the cross-section of the shaped body (15), the invention proposes to form the core region of the shaped body (15) from a particle additional mass which is specifically moved thereto and compressed and which, on compression of the shaped body (15) by cheek plates (2 to 5) surrounding it, acts reactively as a crushing zone (28). In this way, a continuous compression of the shaped body even of large cross- section is achieved, and at the same time a particularly powerful compression of the peripheral regions of the shaped body. The strength and flexural rigidity of such shaped bodies (15) is particularly great, making them suitable even for forming railway sleepers.

Abstract: The invention relates to a method for the rolling of crankpins of crankshafts with different eccentricities. In the case of crankpins to be rolled which are close together, not all crankpins can be rolled simultaneously due to the lack of space. It is therefore proposed that all crankpins be split up into two groups and that they be rolled in groups one after the other, in which arrangement the crankpins which are not directly adjacent in each case belong to each group. To this end, crankpin-rolling devices are provided which are arranged together in such a way as to be axially displaceable between two predetermined or predeterminable positions and can be fixed in these  positions, the crankpin-rolling devices being at such a distance from one another in the displacement direction that at least one crankpin can be located between them in the working position.

Abstract: The safety switching panel is inserted into the ground in front of machines which are not to be touched in operation. It is connected in a circuit. When stepped on, it switches the machine off and/or triggers an alarm. The panel is intended to retain its functional capability even when penetrated by oil and in the case of other disturbances. For this purpose, it contains, between a bottom and a cover panel, a hose with a conductive layer on its bottom and a further conductive layer underneath its top. These layers are connected in the circuit. When the panel is stepped on, the hose is compressed, the conductive layers touch one another and close the circuit. <IMAGE>

Abstract: Disclosed herein is a method of preparing a cubic boron nitride sintered compact by adding a cubic boron nitride synthetic catalyst to atmospheric pressure type boron nitride. Simultaneously with such addition of the cubic boron nitride synthetic catalyst to the atmospheric pressure type boron nitride, 0.01 to 5.0 percent by weight of a hydroxide of an alkaline earth metal is added to the atmospheric pressure type boron nitride. Then, with action of the cubic boron nitride synthetic catalyst, high temperature/high pressure treatment is performed on the atmospheric pressure type boron nitride under a thermodynamically stable pressure condition for cubic boron nitride, thereby converting the atmospheric pressure type boron nitride to cubic boron nitride. The cubic boron nitride sintered compact thus obtained contains 0.01 to 5.0 percent by weight of an oxide of the alkaline earth metal only in triple points of cubic boron nitride grains. The cubic boron nitride grains are densely bonded with each other.

IPC: A01D43/14

Abstract: The invention relates to a machine for applying fertilizer, especially to grass fields and using fertilizer of a type which is delivered in liquid form by spreading by means of nozzles. The fertilizer is usually of the nitrogen-phos­phoros-potassium type or the urea type. The machine ac­cording to the invention is characterized in that its spreading nozzles (9) are placed beneath a mower known per se, for instance of the disk cutter type. The nozzles are placed on a common distributing bar (8) which is placed immediately behind the cutting devices (1) so that the fer­tilizer liquid will be spread over the stubble (S) at the same time as the swath (A) is lifted off the ground. The cut crop is then deposited on top of the stubble behind the mower and in this way covers the now fertilized stubble. The fertilizer will then exercise its effect in a humid mi­croclimate beneath the swath and will in this way have an enhanced and accelerated effect. 
     As to working conditions, the method presents the advantage that the laying in swaths and the depositing of the ferti­lizer take place in one operation. It is furthermore an important advantage that the fertilizer application takes place without the delay which the tedding or drying of the swath will otherwise give rise to so that the after-growth of the field will be optimal.

Abstract: A system for the destruction of organic waste material such as halogenated organic compounds, and related matter. In one embodiment the waste material is reduced with a gaseous reducing agent such as hydrogen above about 600°C, the gaseous products are condensed and cooled in the presence of an aqueous mist at about 5°C, and condensed organic and aqueous material is collected and the aqueous portion recycled into the condensing and cooling steps. In another embodiment, where acid gases (for example, hydrogen halides) are produced during reduction, the gaseous products are condensed in the presence of aqueous mist at about 85°C and a major portion of the aqueous mist condenses as acidic water which is collected and neutralized. Remaining gaseous components are then cooled to about 5°C as in the previous embodiment. In further embodiments, the remaining uncondensed gaseous products are oxidized with a gaseous oxidizing agent at a temperature above about 1000°C. The process thus allows destruction of organic waste, recovery of reduced products, and oxidation of unrecovered products. The system includes a reduction vessel wherein hydrogen is used directly in intimate mixing relation with pulverized waste material, and after completion of a residence time sufficient to reduce the organic compounds, the gaseous by-products pass to an adjacent acid recovery and neutralization vessel and/or reduced product recovery vessel and combustor.
