Title: Titanium dioxide nacreous pigments and process for the preparatin thereof
IPC: A61K8/18
Filed: 1973-06-19
Abstract: 1416960 Platelike CaSO 4  coated with TiO 2  MEARL CORP 19 June 1973 [21 July 1972] 29040/73 Headings C1A and C1N [Also in Division C4] Platelike CaSO 4  particles, 5-70 Á long and 0À1-1 Á thick, having a coating of crystalline TiO 2 , 5-500 nm. thick, are prepared by depositing amorphous TiO 2  on platelike gypsum particles and calcining to dehydrate the CaSO 4  and crystallize the coating. The CaSO 4  may then be dissolved out to give TiO 2  platelets. The gypsum may be produced by precipitation from soluble Ca and sulphate salts in the presence of an organic modifier, e.g. succinic, gluconic, citric, malic or oxalic acid or their salts, glycine, glycylglycine, alanine, gelatine, polyacryle acid or polyacrylamide. Preferred salts are CaCl 2  and Na 2 SO 4 ; others are listed. Alternatively the gypsum may be obtained from CaSO 4 À¢H 2 O or natural selenite (by grinding and classifying). The TiO 2  coating may be produced by hydrolysis at 70-103‹ C., preferably under reflux, of TiOSO 4  (partially neutralized with NaOH, KOH, NH 4 OH, NaHCO 3  or (NH 4 ) 2 CO 3 ) or TiCl 4 , in the presence of the gypsum. To produce rutile, the gypsum is treated with a solution of a tin salt, e.g. SnCl 2  or SnCl 4  in aqueous HCl, before or during TiO 2  precipitation, and optionally also with a solution of an Al compound, AlCl 3 , Al 2 (SO 4 ) 3  or NaAlO 2 , after TiO 2  precipitation the product then being calcined at 600-950 C. To produce anatase, the TiO 2 -coated gypsum may be treated with a solution of an Si compound, e.g. Na 4 SiO 4 , and the pH then reduced with HCl, calcination being effected at 800-950‹ C.; or the untreated coated gypsum may be calcined at 600-760‹ C. The unsupported TiO 2  may be obtained by dissolving the CaSO 4  with HCl, HNO 3 , H 2 SO 4 , acetic acid, NaOH, NH 4 OH, KOH, or EDTA or its Na salts. The product still contains up to 20% CaSO 4 , and Sn, Al or Si oxides, if used.

IPC: H01Q5/40
Filed: 1953-10-23
Abstract: 741,911. Aerials. BELLING & LEE, Ltd. Oct. 25, 1954 [Oct. 23, 1953], No. 29357/53. Class 40 (7). An aerial assembly comprising two aerials which are mechanically inter-related for mounting on a single support, the aerials being capable of receiving signals in different frequency bands and having only a small effect on each other, includes a halfwave dipole for operation at the lower frequency and a plurality of closely spaced conductors forming a reflective surface which is part of the higher frequency aerial. Each conductor is arranged to lie wholly in a plane perpendicular to the half-wave dipole. In a first embodiment a half-wave dipole 1 backed by a parasitic reflector 2 is provided for operation at the lower frequency and the conductors 6 forming the reflective surface are supported by but insulated from the upper parts of the elements 1 and 2. A stouter conductor 7 forms the support bar for a broadside array 5 of elements working at the higher frequency. These elements are spaced a quarter of a wavelength in front of reflective surface by members 8. Where the half-wave dipole 1 is specially mounted in a rotatable coupling 10 and the conductive rods 6 supported through insulators at their centres the whole higher frequency aerial may be rotated for directional adjustment. The ends of the conductors 6 are held in vertical insulating supports 11 and the reflecting surface may be a plane one (Fig. 2, not shown) or parabolic as in Fig. 3. The array of elements 5 may be stacked vertically so as to lie along the focal line of the parabolic reflector. In Fig. 4 the lower frequency dipole 1 is horizontal and the conductors 6 are insulated and mounted so as to extend horizontally in a vertical plane, an array of higher frequency elements 5 being arranged as described with reference to Fig. 1. The top and bottom of the reflecting surface may extend forward so that a parabolic reflector with a horizontal focal line is formed (Fig. 5, not shown). In a modification of the Fig. 4 embodiment the conductors 6 and elements 5 may be arranged to extend vertically and in this case the reflector surface need not be a plane perpendicular to the dipole 1 but may make an angle other than 90 degrees with it in the horizontal direction. In the modification, too, the reflector may be parabolic.

Title: Improvements in bis-quaternary salts and processes for their preparation
Inventor: SLACK RONALD
IPC: C07D295/02
Filed: 1950-12-15
Abstract: The invention comprises heptamethylene-bis-N-(N-methylmorpholinium) salts.  They may be made by reacting a compound X-(CH2)7-X and a compound Y, X representing an N-morpholino group or the acid residue of a reactive ester and when X is the morpholino group Y is a reactive methyl ester and when X is the acid residue of a reactive ester, e.g. a halogen atom, Y is an N-methyl-morpholine followed by conversion to the required salt if necessary by metathesis or via the hydroxide.  In the case of salts in which the anion corresponds to that of a reactive ester, e.g. halide or p-toluene-sulphonate, it is preferred to either form the corresponding heptamethylene bismorpholine and treat the free base with a reactive methyl ester, e.g. methyl chloride, bromide, iodide or sulphate, or condense a corresponding reactive heptamethylene di-ester, e.g. dihalide, with N-methyl morpholine. Other specified salts are tartrates, citrates and phosphates. The compounds have a selective paralyzing action upon parasympathetic ganglia.  In an example, 4-methylmorpholine is treated with 1,7-dibromoheptane to yield heptamethylene - 1,7 - bis - N - N - methyl - morpholinium) di-iodide.
