Title: Process for the end-to-end dimerisation of olefins
Inventor: METCALFE CHRISTOPHER JOHN LEON
IPC: C07C2/12
Filed: 1966-02-09
Abstract: Olefins are dimerized to give mixtures containing relatively high proportions of end-to-end dimers by contact at an elevated temperature below 400 DEG  C. with a catalyst prepared by impregnating an X-type molecular sieve zeolite with a nickel salt in an ionic solution of sufficient strength to ensure substantially complete ion exchange with the zeolite, washing the zeolite with an undissociated or weakly dissociated solvent for the nickel salt (e.g. water), and finally calcining at between 200 DEG  and 800 DEG  C. Suitable nickel salts are the chloride, sulphate and nitrate, and the complex formed by dissolving nickel formate in ammonia.  Suitable olefinic monomers include cis- and transbutene-2, 4 - methyl - pentene - 1 and hexene1, and examples describe the dimerization of butene-2 to give mixtures containing, after hydrogenation, 3.8-17 wt. per cent of noctane. A similar zeolite not containing nickel gave only 2% n-octane in the hydrogenated dimer.ALSO:An X-type molecular sieve zeolite is impregnated with a nickel salt in an ionic solution of sufficient strenght to ensure substantially complete ion exchange with the sieve, the impregnated sieve washed with an undissociated or weakly dissociated solvent for the nickel salt (e.g. water) to remove excess nickel salt, and the washed product calcined at between 200 DEG  and 800 DEG  C.  The impregnation and washing may be repeated before the calcination.  Suitable nickel salts are the chloride, sulphate and nitrate, and the complex formed by dissolving nickel formate in ammonia.  The products are dimerization catalysts (see Division C5).

Title: Process for the production of polyakyleneglycol ether derivatives of aromatic aminocarboxylic acids
Filed: 1950-12-14
Abstract: The invention comprises the polyalkyleneglycol ether derivatives of aromatic aminocarboxylic acids obtained by heating to condensation an aromatic aminocarboxylic acid containing at least one free amino or one free carboxylic group with more than a three mol proportion of an alkylene oxide.  The aromatic aminocarboxylic acid may contain alkyl radicals having at least 6 carbon atoms directly attached to the nucleus either by a carbon linkage or through an oxygen or sulphur atom.  The reaction may be carried out under increased pressure and also, if desired, in the presence of diluents.  An alkaline reacting substance, e.g. an alkali metal hydroxide, may be added to the reaction mixture. Suitable aromatic aminocarboxylic acids are mono- and poly-aminocarboxylic acids of the benzene, naphthalene and anthracene series.  Ethylene and propylene oxide are mentioned as examples of suitable alkylene oxides.  The polyalkyleneglycol ether derivatives of aromatic aminocarboxylic acids may be heated to condensation with one to three mol proportions of an aliphatic monocarboxylic acid containing at least 6 carbon atoms.  In the examples: (1) p-aminobenzoic acid is heated with ethylene oxide in a pressure vessel; (2) anthranilic acid is treated as (1); (3) p-aminobenzoic acid is heated with ethylene oxide and sodium hydroxide and the reaction product is heated with a further quantity of ethylene oxide; (4) the reaction product of (3) is heated with stearic acid in the presence of a small amount of p-toluene sulphonic acid.ALSO:Cosmetic preparations e.g., salves, creams and lotions, which may be used for protection against sunlight and other light are obtained by dissolving polyalkyleneglycol ether derivatives of aromatic aminocarboxylic acids (see Group IV(b)) in water and in oils which may contain fats.  The preparations may also contain alkaline earth metal salts or other salts of polyvalent metals, and also acids, dyestuffs and perfumes as well as products having a disinfecting action and medicaments e.g., sulphonamides, hormones and vitamins.  In the examples: (1) (3) the polyalkyleneglycol ether derived from ethylene oxide and p-aminobenzoic acid is dissolved in water; (2) a salve is obtained by mixing petroleum jelly with the polyalkyleneglycol ether derived from ethylene oxide and anthranilic acid; (4) the polyalkyleneglycol ether derived from ethylene oxide and p-aminobenzoic acid is reacted with stearic acid and is dissolved in water or mixed with petroleum jelly.

Title: Immobilized enzyme conjugates
IPC: B01J31/00
Filed: 1976-02-17
Abstract: The enzyme fixed to a support is composed of a combined organic-inorganic base material, which consists of an inorganic porous support having an organic polymer, which contains functional groups, partially adsorbed and enclosed in its pores, and of an enzyme which is partially adsorbed to the base material and bound covalently to the functional groups of the organic polymer in the terminal regions of this polymer. Such immobilised enzymes are of use in the biochemical and fermentation industries. They are obtained, in particular, by drenching a porous support with a solution of a polyfunctional organic compound and treating the impregnated support with an excess of a bifunctional monomer. Subsequently, the enzyme is added, part of which enzyme then binds covalently to reactive groups of the polymer which has been formed and which is present in and on the support. During this procedure, the biochemically active residues of the enzyme must not be blocked or altered.

In a circuit arrangement for measuring the phase difference between two currents, particularly for the indicator of a radio altimeter for indicating height above the earth or objects thereon in which the phase difference is measured between the transmitted wave and the wave received after reflection, the two inputs whose phase difference is to be measured are fed in parallel and push-pull respectively to two rectifiers, the outputs of which are fed in opposite directions through a high resistance which may be constituted by the indicating meter or the indicating meter may be connected across the high resistance. The two inputs A1 B1, A2 B2 whose phase difference is to be measured are applied by means of transformers T1, T2 in parallel and push-pull respectively to metal rectifiers R1, R2, and a microammeter M common to the two circuits measures the differonce of the currents flowing through them and may be calibrated to read heights in feet. Resistances r1, r2, r3 are connected in series with the rectifiers R1, R2, the resistance r2 having a movable contact P which is adjusted so that for no phase difference the microammeter M reads zero. A phase shifter may be included in the circuit to transfer the scale at the extreme ends of the instrument M to the central portion. The range may be altered by changing the modulation frequency. In order to detect small objects above the ground level an amplifier valve V may be connected across the terminals of the instrument M, its output being connected to one pair of plates D1, D2 of a cathode-ray oscillograph. The other plates D3, D4 are connected to an A.C. supply of low frequency.
