Abstract: 555,757. Refractory materials. GOLDSCHMIDT, V. M. Oct. 6, 1939, No. 27412. [Class 22] A bonded highly refractory material contains 40-75 per cent. by weight, preferably 55-70 per cent. of granular material rich in magnesium orthosilicate, such as natural olivine or dunite rock, and at least about 25 per cent. by weight of a more finely comminuted refractory substance which is free from or is poor in alumina, such as refractory spinels, the porosity of the bonded material being less than 24 (preferably less than 20) per cent. by volume. At least two of the following steps are included in the manufacture : (1) selection of raw materials which do not contain more than about 5 per cent. by weight in aggregate of such hydrates and easily hydratable compounds as clay, magnesium hydroxide or caustic magnesium oxide, (2) limitation of the amount of liquid used for plasticizing the batch to less than 6 per cent. by weight of the batch, and (3) firing the bonded refractory at a high temperature so that a shrinkage of not less than 2 per cent. by volume takes place. In cold bonding the material to shaped products such as bricks, cellulose waste liquor, solutions of molasses, boric acid, sodium silicate, or magnesium chloride may be used.

Title: Process for the production of phosphorus- and sulphur-containing organic compounds
IPC: C07F9/50
Filed: 1954-09-24
Abstract: Phosphorus- and sulphur-containing organic compounds are obtained by reacting a phosphine with a sultone, the reaction being carried out in the presence of an acid combining agent, e.g. anhydrous sodium carbonate, when the phosphine is a primary or secondary phosphine. Specified sultones (cyclic anhydrides of organic hydroxy sulphonic acids preferably with 5 or 6 ring atoms) are propanesultone, butanesultone, isobutanesultone, tolylsultone and 1,8-naphthsultone. The phosphines are defined as those having the general formula R.PH2, (R)2PH, and (R)3P, in which R is an organic residue attached to the phosphorus atom by means of a carbon atom and which in the case of the secondary and tertiary phosphines may be the same or different residue.  The reaction may be carried out in the presence of an inert organic solvent or diluent.  In the case of the primary and secondary phosphines the products are phosphorus-containing sulphonic acids, e.g. from propane sultone and a phosphine (R)(R1).PH the product is (R)(R1).P.CH2.CH2.CH2. SO3H, whilst in the case of the tertiary phosphines the products are probably internal phosphonium salts. Specified phosphines are mono-, di- or tri-alkyl phosphines, mixed di- and tri-alkylarylphosphines, arylphosphines, and cycloalkylphosphines.  Examples are given for the reaction of triphenylphosphine with propanesultone to form a crystalline product, the reaction being carried out by heating at 70-170 DEG  C. in the absence of a solvent or by refluxing the reactants in xylene solution.

Title: Improvements relating to pulse coding systems
IPC: H04L9/18
Filed: 1970-06-08
Abstract: 1282184 Adder C W NELSON Jnr 8 June 1970 [13 Aug 1969] 27634/70 Headings G4A and G4H The invention relates to an adder for producing ternary coded signals from data coded in " signed binary," i.e. where " 1 " and " 0 " are represented by " + + " and " - - ." Digital binary data is stored in registers A and B in signed binary as shown in Fig. 9. The + and - signs are added according to the table of contents shown in Fig. 9, the contents of one register being added to the corresponding contents of the other register shifted by one half bit position. The registers A and B are coupled by a loop of resistors as shown, the resistors also being coupled to register C. Voltages applied to the resistors by contacts at the registers A, B determine the voltages at register C. For A 1  = -, B 1 = - therefore C 2 = -. For A 2 = +, B 1 = - C 3 = 0 and for A 2 = + B 2 = 0, C 4 =+. C 1  for which no position in the B register corresponds to the A register is obtained by adding B8 to A1 and C17 is arranged to be identical to B8. The sum in the C register can be easily decoded into its component parts and a decoder is illustrated in Figs. 10, 10a, 10b, 10c, Fig. 10, of which is shown. C17 is directly connected to B8 via a contact 121 and the value of C17 is used to operate relay 124 and contact 125. The value of C16 closes or opens contact 126 to operate relay 127 and as shown contact 128 to supply a voltage to contact 125. This feeds terminal 130 A8 and relay 131. In a similar manner C15 operates relay 134 so that a voltage is fed via contacts 135 and 132 to terminal 137 B7 and relay 138.
