Title: Process for making titanium dioxide
IPC: C01G23/07
Filed: 1962-05-15
Abstract: A continuous process for obtaining a TiO2 pigment essentially spherical and having an average particle diameter between 0.2 and 0.4 microns comprises (a) continuously reacting in a first reaction zone, at temperatures above about 650 DEG  F., vapours of a titanium halide, a free-oxygen-containing gas, and a hydrogen-containing gas, said hydrogen-containing gas being present in at least sufficient quantities to provide enough hydrogen to react with 50 mole per cent of said titanium halide and said oxygen sufficient to maintain an oxidizing flame, in accordance with the stoichiometry of the reaction. TiX4+2H2+O2-->TiO2(S)+4HX wherein X is a halogen, to produce TiO2 which is spherical and has an average particle diameter below about 0.1 micron, and (b) continuously reacting at a temperature above about 1200 DEG  F. in a second reaction zone, the TiO2 product of the first reaction zone in aerosol form, a free-oxygen-containing gas, and at least 19 times as much vaporized titanium halide as is introduced to said first reaction zone, in accordance with the reaction.  TiO2(s)(<0.1m )+MTiX4(g)+MO2(g) -->(M+1)TiO2(s)(>0.2m )+2MX2(g) wherein X is a halogen and M is at least 19 in each case, and recovering the resultant TiO2 product. The free-oxygen-containing gas may be pure oxygen and/or air.  The hydrogen-containing gas may be pure hydrogen and/or ammonia, methane, ethane or other hydrocarbon-containing gas.  The titanium halide may be a mixture of titanium halides, a component of the mixture being titanium tetrachloride. The process may be carried out in a single, two-zone reaction chamber, or in two separate but adjacent reaction chambers.  The reaction, which is effected at above about 1200 DEG F., may be aided by preheating the reactants or by supplying heat by a combustion involving the oxidation of a fuel, for example carbon monoxide which is substantially free of hydrogen.  In an example, 2 lb./hr. TiCl4 vapour and 138 s.c.f.h. oxygen, preheated to 300 DEG F., is fed concurrently with 16 s.c.f.h. hydrogen at ambient temperature to a 4 inch diameter by 12 inches long ceramic reaction chamber, thereby producing gaseous hydrogen chloride and spherical titanium dioxide particles of 0.03 microns diameter.  The hot products are led to a 2 ft. diameter by 8 ft. long ceramic reaction chamber, to which there is fed continuously a mixture of 998 lb./hr. of titanium tetrachloride vapour and 1860 s.c.f.h. oxygen, preheated to 700 DEG  F.  The resulting reaction at 2000 DEG  F. produces 421 lb/hr. titanium dioxide, 744 lb./hr. chlorine, which is recycled to produce additional titanium tetrachloride, and 3 lb./hr. gaseous hydrogen chloride.  The product is spherical in shape, with 90% in rutile crystal form, and of 0.24 microns particle size. Specifications 707,389 and 707,560 are referred to.

Filed: 1947-07-14
Abstract: 650,310. Cutting-machines. GOSS PRINTING PRESS CO., Ltd. July 14, 1947, No. 18670. Convention date, Nov. 27, 1946. [Class 31 (i)] In mechanism for cutting sheets from a travelling web 14 by means of a pair of cutting cylinders 10, 11 provided with co-operating longitudinally extending cutting blades 12, 13, each cylinder is provided at spaced points along its length with rings of sprocket teeth 40 around which an endless chain 23, 24 passes, the cutting blades are formed with cut-away portions or recesses adapted to allow passage of the links of the chains, and the chains are so arranged as to be in pairs with adjacent reaches which form a confined path along which the cut sheets are conveyed from the cylinders to further guide or forwarding means. The cut sheets are thus prevented from following the cutting cylinders or bunching and jamming in the mechanism. Where the blades 12, 13 intersect with the rings of sprocket teeth, a tooth 40 is omitted to accommodate the blade, the latter being provided with a pair of spaced slots to receive the chain links and an intervening blade portion filling the space between the links (see Fig. 4, not shown). The chains pass around guide rollers or sprockets 31 so as to convey the cut sheets between guides 17, 18 to forwarding tapes 19, 20 which pass around roller portions of the sprockets 31. The cylinders 10, 11 are preferably driven rollers. The chains also pass round further sprockets 30 or rollers mounted at the end of arms 33 pivotally mounted at 34, and the tension of the chain may be adjusted by means of a set screw 36. A plurality of blades may be provided on each cutting cylinder. The cut-away portions of the blades leave uncut tabs between adjacent sheets and these, if not immediately torn, contribute to the guiding of the sheets. The Specification as open to inspection under Sect. 91 comprises also the elimination of the sprocket teeth 40 by providing grooves in the cylinders 10 and 11 for the chains 23, 24 and in this case the sprockets 31 are driven to drive the chains. This subject-matter does not appear in the Specification as accepted.

Title: Process and apparatus for volume range expansion applied to the reproduction of electric oscillations
IPC: H03G7/02
Filed: 1937-07-07
Abstract: 498,235. Automatic volume control. KOLB, O. K. (Schlegel, K. H. F.) July 7, 1937, No. 18889. [Class 40 (iv)] [Also in Group XL] In a soundreproducing circuit giving volume-range expansion, the degree of expansion is adjustable without affecting the maximum volume by means of a linear potentiometer P1, which controls the proportion of a biassing voltage, derived from the acoustic signals or from a pilot signal, to be applied to a variable gain or loss device having an exponential or logarithmic law, and is ganged to a logarithmic potentiometer P2 controlling the over-all gain independently of the amplitude of the signals, e.g. by adjusting the acoustic signal input. Additional potentiometers P3, P4 are connected as shown, the former being adjusted initially to ensure correct relations between the effects of PI and P2, and the latter being adjusted to control the maximum volume. When compression has been effected so that a1/a2=k.log t1/t2 where a1, a2 are the signal amplitudes corresponding respectively to coefficients of transmission t1, t2 in the compressor, the control voltage for the expander can be obtained by direct rectification of a portion of the signal currents. When, however, the compression is such that log a1/a2=k.logt1/t2, a portion of the signal currents must be passed through a logarithmic compressor before rectification to furnish the control voltage. Specification 354,605, [Group XL], is referred to.

Abstract: 240,598. Spearing, K. A., and Bock, J. Kerr-. Aug. 9, 1924. No Patent granted (Sealing fee not paid). Purifying liquids.-In water-softening apparatus in which the water is brought into contact with a substance such as zeolite or natrolite capable of reacting with the minerals in the water, a substance such as rock salt for regenerating the active substance is introduced in solid form, and a solution of this substance is formed during the normal operation of the apparatus, means being provided to introduce the solution to the active substance. A cylindrival tank 1 is divided into compartments 3, 4, 5 by perforated partitions 6, 7, and supports a eistern 2 divided by a partition 10 with holes 10<a> into compartments 8, 9. The zeolite &c. is contained in the compartment 4 and the regenerating substance is placed in the compartment 8. Water enters by the pipe 27 and passes through the cook 11, pipe 28, and chamber 5 into the compartment 4. The softened water leaves the chamber 3. in which a filtering medium may be placed, by a pipe 32 and non-return valve 33. A branch 34 leads some of the water through a float-operated valve 35 into the chamber 8. A solution of rock salt, is formed which passes through the holes 10<a> into the chamber 9, whereupon the valve 35 closes. When it is desired to regenerate the substance in the chamber 4, the cock 11 is operated to put the chamber 9 into communication with the chamber 5 through a pipe 30 and a passage 18 in the cock, the main water supply being cut off. The solution in the chamber 9 passes through the compartment 4, the displaced water in the chamber 3 passing by a pipe 31 and the cock 11 to a discharge pipe 29. On the active substance being regenerated, the cock 11 is turned to put the chamber 3 into communication with the atmosphere through the pipes 31, 30 and the compartment 9, and the compartment 4 is drained through the passage 18, cock 11, and pipe 29. On the cock 11 being turned to its original position, the apparatus again is ready to soften the water. A pointer 25 on the cock handle 24 registers with markings on a plate 26. Wire gauze may be placed over the holes 10<a>. According to the Provisional Specification, a flow of air from the compartment 9 may follow the salt solution, assisting the mixing of the solution with the active substance, and the solution may be delivered from the compartment 9 by means of a syphon.

Filed: 1922-07-12
Abstract: 195,585. Lanhoffer, I. E. April 3, 1922, [Convention date]. Rotary furnaces for roasting or calcining cement. Relates to furnaces of the kind comprising two elements or sections, operating at different temperatures, through which the material is passed in succession. Part of the gases from the high-temperature section are utilized for removing dust or powder from, and for heating, the material during its passage from the lowtemperature section to the high-temperature section, the remainder of such gases being freed from dust and powder and passed through a heatrecovery apparatus, after which they may be delivered wholly or in part to the low-temperature section or utilized elsewhere. As shown, the gases leaving the high-temperature section a are in part passed through a tube i, through which the material from the low-temperature section b is transferred to the high-temperature section, and are discharged into the low-temperature section around a central tube u. The remainder of the gases is passed through the tubes e of a steam boiler or other heat-recovery apparatus, after which they may be further divided, a part being delivered to the low-temperature section through the tube u, while the remainder is passed through a feed-water heater r and led away for utilization in drying the raw material or the coal, or otherwise. The proportions of the gases at each division may be regulated by dampers. Dust carried by the gases is deposited in chambers c and d. The gases are drawn through the furnace and heat-recovery apparatus by fans t and q. The furnace may be regulated also by varying the speed of rotation of the sections a and b and by varying the intensity of the flame issuing from the burner a<1> into the high-temperature section. The high temperature section and the discharge end of the low-temperature section are lined with refractory material, while the remainder of the low-temperature section may have a metallic lining to take up heat from the gases. The furnace sections are shown horizontal, but they may be suitably inclined. Specification 195,612 is referred to.

Title: Data processing apparatus
IPC: G06F7/02
Filed: 1960-06-01
Abstract: 938,573. Digital electric calculating apparatus. RESEARCH CORPORATION. June 1, 1960 [June 30, 1959], No. 19360/60. Class 106 (1). In data-processing apparatus a single instruction cycle can result in the comparison of specified orders of two data words, the other orders being excluded by masking. The apparatus can perform all arithmetical operations but is particularly concerned with comparison and the optional feature of subtraction. Assuming that the first word to be compared is already in accumulator 16, an instruction word extracted from memory 10 and stored in instruction control 24 comprises left and right-hand portions, Fig. 2. Bits L10, L11 in combination indicate whether all, the left or the right half, or none of the word is to be compared and mask the corresponding parts of the B register 18. The right-hand part of the instruction contains the address in the memory 10 of the second word to be compared. This word is then stored in A register 14 and those digit positions in the A register 14 and the accumulator 16 which correspond to the masked positions in the B register 18 are then set to O. If the comparison is true, programme counter 28 steps on. If the comparison fails the programme counter 28 is stepped to a branch instruction to enable an immediate return to a second comparison test using a different address. If the instruction in Fig. 2 contains 1 in bit L12 then after a successful comparison subtraction is effected in the same cycle by complementary addition in known manner. The several possible operations in one cycle are time-spaced and enabled where required by the presence of a pulse in a timed sequence (Fig. 3, not shown). The hardware is as described in Specification 802,656.
