Title: Process for the production of etherified aminotriazine resins
IPC: C08G12/42
Filed: 1965-08-10
Abstract: Etherified aminotriazine resins with a low formaldehyde content (e.g. 0.1 to 0.8% by wt.) are prepared by steam distilling a solution, in an organic solvent, of an etherified amino-triazine resin with a formaldehyde content of up to 10% by wt.  The resin solution may be treated either prior to or after steam distillation with either: (1) a peroxide compound, e.g. H2O2, a peroxide, hyperoxide or sesquioxide of an alkali metal or alkaline earth metal, a peroxyacid or its salts with S, P, N, C or B, or a peroxy-hydrate,(2) sufficient ammonia to form hexamethylene tetramine with the residual HCHO or (3) a sulphur compound which is capable of forming either a HCHO-bisulphite or HCHO-sulphoxylate adduct.  Examples of (3) are sulphites, pyrosulphites, dithionates, dithionites and sulphoxylates, alternatively SO2 may be used; it may either be neutralized afterwards with a strong base (e.g. NaOH) or passed into a solution which has been previously treated with a strong base.  Examples relate to the preparation of paints with TiO2, an alkyd resin and aminotriazines resins both untreated and treated according to the invention.

Abstract: 994, 873. Electric control systems. JOSEPH LUCAS (INDUSTRIES) Ltd. Oct. 5, 1961 [Oct. 10, 1960], No. 34597/60. Heading G1N. [Also in Division H3] In an electronic servomechanism the D.C. potential at the wiper of a potential divider 8 is representative of a controlling variable, e.g. the suction in the inlet manifold of an I.C. engine, and determines the operating condition of a circuit comprising three transistors 12, 15, 18 and the differential field windings 10a, 10b of a D.C. motor 10 which operates to control, e.g., the fuel supply to the I.C. engine, and also to bring the system into equilibrium by adjusting a variable resistor 9 in series with potential divider 8. Transistors 12 and 15 form a Schmitt trigger circuit, only one of them being conductive at a time. When 12 is conductive, the third transistor 18 also conducts, and the collector current in field winding 10b determines the direction of rotation of motor 10; when 15 is conductive the current in field winding 10a drives motor 10 in the opposite direction. At equilibrium, 12 and 15 conduct alternately, the frequency of oscillation being increased by a feedback circuit comprising a resistor 20 and a capacitor 21 from the collector of 15 to the base of 12, so that the motor 10 is maintained stationary by its inertia. In one modification, field windings 10a, 10b are replaced by oppositely acting electromagnets; in another, the armature or a single field winding of the motor is connected between the collectors of two alternately conducting transistors, the direction of rotation depending on which transistor is conducting.

Abstract: In the hydrogenation of carbon monoxide in the presence of a catalyst suspended in an oil at elevated temperature and pressure, the oil and catalyst are divided into a number of partial amounts and the synthesis gas is collected after passage through each amount before passing together with the products through the next amount and cooling the gas before passing through the next portion to maintain the most favourable reaction temperature.  In the embodiment of Fig. 1, the gas entering by line 4 is mixed in mixer 8 with contact oil drawn by line 9 from the first partial amount.  The mixture is cooled by cooler 10 and delivered to the first stage.  Similarly gas drawn from above the first partial amount by line 18 is mixed in mixer 8a with oil from the next stage, cooled and delivered to the next stage. Product after further cooling is obtained by line 26.  Fresh contact oil may be added by line 31 and spent oil removed by line 32.  In a second embodiment <PICT:0930656/III/1> <PICT:0930656/III/2> (Fig. 2, not shown), the oil is drawn from the top of each portion, cooled, mixed with gas from the preceding portion and injected back into the bottom of the portion.  In Fig. 3, each portion is partially contiguous with the next but has a gas space above it, the gas passing from stage to stage through openings 60. Cooling is effected by internal coolers 63.  Different catalyst concentrations and temperatures may be maintained in each stage.
