Title: Improvements in the preparation of titanium dioxide pigments
IPC: C01G23/053
Filed: 1961-08-17
Abstract: Rutile is prepared by calcination at or above about 1000 DEG C., of a hydrous titanium dioxide containing prior to calcination, rutile seeds, (in addition to those used in the initial hydrolysis) a water-soluble aluminium salt, a water-soluble phosphate and a basic potassium salt. The calcination is continued until the titanium dioxide is substantially completely converted into the rutile form. Ordinarily, the calcination is effected in the presence of 1-6% rutile seeds, 0.3-2.5% of a water-soluble aluminium salt (calculated as Al2O3) 0.1-0.5% of a watersolubl phosphate (calculated as P2O5) and 0.1-1.0% of a basic potassium salt (calculated as K2O) based by weight on the titanium dioxide. However, if the ore from which the titanium sulphate solution is obtained contains phosphorus, then the addition of extra phosphorus compounds may not be required. The seeds added before hydrolysis can be those obtained according to Example 1 of Specification 513,867, by halide hydrolysis in caustic soda and the seeds added after hydrolysis and before calcination, can be obtained by boiling washed hydrous titanium dioxide in a caustic soda solution for 4 hours, washing the precipitate, resuspending it in HCl solution and heating the suspension for 3 hours. In Example II, the rutile seeds are obtained by treating TiCl4 solution with a solution of caustic soda, neutralizing the suspension obtained, and then washing out 75% of the soluble salts present. The suspension thus obtained is added to titanium sulphate solution prior to hydrolysis to obtain hydrous titanium dioxide. The product is separated, washed and reslurried in water, to which is added rutile seeds as prepared in Specification 513,867, and an aluminium sulphate, mono-ammonium phosphate and potassium carbonate. The resulting mixture is dried and calcined at or above about 1000 DEG C.

Patent ES-347350-A1 (ES)
Title: Descaling process and material
IPC: C21D1/70
Filed: 1967-11-18
Abstract: A ferrous metal or alloy member is heattreated, whilst preventing and removing scale formation on the member, by applying to the member, e.g. by brushing, spraying or dipping, a descaling coating composition comprising a KC1 + NaCl salt mixture with refractory cement and water, heating the coated member above the critical (austenitizing) temperature e.g. to 1200 F., and quenching e.g. with air or water the heated coated member. The process is particularly for martensitic hardening without transformation to bainite, pearlite or ferrite. The composition comprises by weight 67-83% of the salt mixture and 17-33% of refractory cement (dry basis), equivalent to 63-80% of the salt mixture and 20-37% of refractory cement (wet basis e.g. containing 16-20% water). Preferably the salt mixture comprises by weight 30-55% KC1 and 45-70% NaCl, and the cement is an aluminium silicate based refractory. The coating composition may also contain boric acid and/or Na 2 B 4 O 7 , e.g. in amount of 3% by weight of the slurry.
Patent ES-352036-A1 (ES)
Title: Means for delivering measured quantities of semiliquid or pasty materials
IPC: B65B3/32
Filed: 1968-03-27
Abstract: A pump for dispensing adjustable measured quantities of semi-liquid material, e. g. mascara, into containers, comprises a cylinder 31, Fig. 3 with an inlet port 29 connected to a supply container 10, Fig. 2, with a compressed air-actuated piston 18, and an outlet port 44 connected to a containerreceiving nozzle 45, a piston 32 being reciprocated in cylinder 31 by a double-acting compressed air motor and having a piston-rod 35 slidably extending through a piston 36 and carrying an axiallyadjustable, threaded sleeve 41. Adjustment of sleeve 41 by wheel 39 determines the axial spacing between pistons 32 and 36, and hence the quantity discharged. In the left-hand position of the pistons shown, the space between the pistons is filled with material through the inlet port, the piston assembly then being moved to the right to close the inlet port and open the outlet port. Piston 36 abuts plate 37 at the end of its movement to the right, the continued rightward movement of piston 32 discharging the material through outlet port 44. The supply container 10 is filled by releasing nuts 15, and removing cover 14 and the piston assembly. On replacing the piston assembly, trapped air is vented through piston-rod 21 and a vent valve, Fig. 1 (not shown). When the container is nearly empty, a collar 25 on piston-rod 21 actuates a switch 26 controlling a solenoid valve to shut-off the compressed air supply to the space above piston 18. Reciprocation of the air motor driving the pump is controlled by a pedal-operated air valve. A pair of pump assemblies is mounted on a stand with a common air supply.
Patent ES-353111-A1 (ES)
Title: Key-operated teleprinter
IPC: H04L25/40
Filed: 1968-04-24
Abstract: A keyboard transmitter has a separate key for each symbol and includes means for automatically inserting case shift signals in to the stream of transmitted characters. On depression of a key To is closed, T1-T5 are selectively closed to represent the character, and T6 is closed if the character is a Figures case character. On closure of To the character represented by T1-T6 is transferred via stores A1-A6 and B1-B6 to store C1-C6. Two further characters can be stored in A1-A6 and B1-B6, whereupon electromagnet Ms is energized to prevent further key operation. When Co is at 1 (i.e. when a character is in C1-C6) a time base unit I generates successive pulses t 1 -t 7 . During t 1 the character in C1-C6 is passed to store S1-S6, the characters in A1-A6 and B1-B6 passed to B1-B6 and C1-C6 respectively, and start polarity applied to the transmission line L. During t 2 -t 6 the content of S1-S5 is passed serially to line, and during t 7 Stop polarity is applied to the line. Subsequently stored characters are transmitted in the same way. When no character is to be transmitted the line is held at Stop polarity. The case bit (from T6) stored in S6 of a character to be transmitted from S1-S5 is passed to store K, and any change in state of K, indicating that the character to be transmitted is not in the same case as the character just transmitted, causes H to prevent read out of S1-S5 and a LTRS or FIGS character as appropriate to be automatically transmitted by way of gates UL2, 3, 5, 6. Should C1-C5 contain a character which has the same significance in either case (e.g. Carriage Return) store S6 is prevented from changing state when the character in C1-C5 is passed to S1-S5, and consequently no case shift character is inserted prior to transmission of this character. Repetition of a character is initiated by closure of T7. This sets W to inhibit gate UZ so that read out from C1-C6 to S1-S6 is prevented. Time base 1 now generates t 1 -t 7 continuously and the character in S1-S6 is passed to line repeatedly until T7 is released.
