Title: Process for producing corrosion-resistant coatings on ferrous metal articles
IPC: C23C22/12
Filed: 1932-10-18
Abstract: Corrosion-resistant coatings are formed on ferrous metal articles by treating the articles with a solution containing a heavy metal phosphate or mixtures of such phosphates and also a substantial amount of a water-soluble salt of zinc or cadmium, the salt not being a phosphate and not being converted to any substantial extent into phosphate in the solution.  A hot solution of approximately equal quantities of a mixture of iron and manganese phosphates and a zinc salt such as the sulphate, chloride, nitrate, or fluoride may be used.  It is stated that some metallic zinc or cadmium is probably deposited in the phosphate coating, and that the coating forms a good base for paint, lacquer and enamel.

Abstract: 1276137 Analogue integration SOLABTRON ELECTRONIC GROUP Ltd 8 June 1970 [10 June 1969] 29432/69 Heading G4G In a measuring technique in which an electrical analogue signal is integrated over a time interval equal to an integral multiple of the period of a noise signal which it is desired to reject, e.g. as in digital voltmeters, control means are employed to multiply the signal as it is presented to the integrating means by a predetermined time-varying weighting function, e.g. a double ramp or a step function shown by the broken and continuous lines respectively in Fig. 3, whereby to permit the rejection of noise at more than one frequency, and to render the rejection less sensitive to a small departure of the measuring interval from an integral multiple of the noise period. Applied to an analogue-to-digital converter of known type (Fig. 4, not shown) in which, subsequent to the end of the measuring interval, a reference voltage of opposite polarity to the signal for measurement is applied to the integrator, and the time for discharge measured by the passage of clock pulses to a counter, the line applying the signal to the integrator is also connected to earth through a tree of resistors and associated switches, the switches being operated in sequence by successive pulses from a clock (Fig. 5, not shown) to provide a weighting function approximating the double ramp function of Fig. 3. For the step function of Fig. 3, a binary counter is followed by a decoder which decodes the counter states corresponding to- 3T/2, - T/2, and 0, and appropriately switches a resistor network. For a step function having only a few steps, such as that of Fig. 3, the weighting may alternatively be performed on the digital side of the analogue-to-digital converter, e.g. if a voltage-to-frequency converter feeds a counter, such that the digital count accumulated during the measuring interval corresponds to the integral of the signal, the decoder controls switches which route pulses either direct to the counter, or through a divideby-three circuit (Fig. 8, not shown).

Title: Production of mesityl oxide and like ª‡-ethylenically unsaturated ketones
IPC: C07C45/74
Filed: 1954-10-13
Abstract: <PICT:0794344/IV (b)/1> a -Ethylenically unsaturated ketones are prepared by the dimeric condensation of a ketone having at least two a -hydrogen atoms with splitting off of water, by heating at a pressure of less than 10 kg/sq. cm., a single liquid phase constituted by a solution of the monomeric ketone in an alkaline aqueous and/or alcoholic medium containing substantially 0.005 to 2 per cent by weight of an alkali metal hydroxide based on the monomeric ketone, at a temperature of substantially 50 DEG  to 150 DEG  C. for a reaction time such as to yield a product in which more than 60 per cent of the converted ketone is in the form of the desired unsaturated dimer, the remainder of the converted ketone being in the form of higher condensation products.  The reation is preferably effected in a closed vessel under at least the autogenous pressure, and for a reaction period at least 10 mins.  The conversion of acetone to mesityl oxide is suitably carried out at 75-120 DEG  C. with a reaction time of 15-60 mins. in the presence of 0.5 to 7 gms. of KOH per litre of acetone.  The condensation mixture may be distilled to recover the resulting unsaturated ketone. Preferably, however, the mixture is allowed to stand at 0-20 DEG  C., whereby part of the unchanged ketone is converted to the hydroxylated dimers. The further reacted mixture may then be neutralized and distilled to recover the hydroxylated dimer and the unsaturated ketone formed in the first stage.  Alternatively, the further reacted mixture is distilled from an acid medium whereby the hydroxylated dimer is dehydrated to yield more of the unsaturated ketone.  A continuous method is described comprising feeding acetone and alkaline catalyst solution through lines 1, 2 and pumps 3, 4 and a preheater 5 into a heated reactor 6 under desired pressure.  The reacted mixture from the reactor may be distilled directly in column 8.  Alternatively, the mixture is passed through a cooler 9 to a reaction chamber 10 at ordinary temperature wherein dimerization of unchanged acetone to diacetone-alcohol occurs.  The reacted mixture is then treated in mixer 13 with a neutralizing amount or more of an acid, e.g. phosphoric acid and distilled in column 8.  Unchanged acetone and solvent are removed overhead and recycled to reactor 6 and mesityl oxide with or without diacetone-alcohol is removed as bottoms with minor amounts of isophorone.  Examples illustrate the continuous conversion of acetone to mesityl oxide at 100-150 DEG  C. using pressures of 3-9 kg/sq.cm. and 0.1 to 1 per cent KOH in water, methanol or ethanol; in most cases, the product is allowed to stand at 10 DEG  C. for 5 hours and then distilled from phosphoric acid to increase the yield of mesityl oxide.  Another example describes the similar conversion of methyl ethyl ketone to give 3-methyl-heptene-3-one-5 and 3:4-dimethyl-hexene-3-One-2 and a minor amount of a C12 ethylene ketone.  Specifications 616,740 and 733,650 are referred to.

The isotridecylammonium salt may be prepared by reacting the Co or Cr complexes with a mixture prepared from primary C 13  alcohols of specified physical characteristics. The salts may be used for the dyeing of printing inks, including ball-point inks, and for surface coating compositions.
