Title: Method of Applying Phosphor Stripes or Dots to a Cathode Ray Tube Faceplate.
IPC: H01J9/227
Filed: 1967-03-31
Abstract: 1,173,645. Luminescent screens. SONY CORP. 31 March, 1967 [2 April, 1966], No. 14882/67. Heading H1D. In a method of making a colour phosphor screen for a colour-switching grid or shadowmask tube involving exposure of photosensitive phosphor slurry material to light projected through an optical mask having opaque areas and transparent areas corresponding to the apertures or holes in the switching grid or shadow mask, the relative position between the optical mask and the tube face plate for the laying down of the phosphors is accurately determined by printing a shadow image of the switching grid or shadow-mask on the face plate (Figs. 5, 7), mounting the optical mask close to the face plate (Fig. 8) and projecting light through the optical mask and adjusting the position of the optical mask until observed moirÚ patterns become bilaterally symmetrical. The shadow image of the switching-grid or shadow-mask is printed on the face plate (Figs. 5, 7) by first coating the entire inner surface of the face plate with photo-sensitive material and then successively irradiating the material with light to raise the adhesion of the material to a maximum value, irradiating the face plate with light through the switching-grid or shadow-mask up to a value to reduce the adhesion of the photo-sensitive material to zero on those areas which have been exposed to light, coating an opaque material over the entire photo-sensitive material coated inner surface of the face plate and washing with water to remove the unwanted areas of material. After the accurate determination of the relative positions of optical mask and face plate by the observation of moirÚ patterns (Fig. 9) the printed areas are removed by rinsing with an acid solution. The colour phosphors are then successively applied (Fig. 11) by the exposure of photo-sensitive phosphor slurry to light projected through the optical mask. After each set of phosphor stripes or dots is formed the optical mask is shifted laterally. Earlier applied phosphors may be opaque or may include opaque material subsequently baked out so that the last phosphor set may be formed by exposure from the outside of the face plate. The pattern on the optical mask may be obtained by calculation or by an electron beam printing method (Figs. 3 and 4) involving (a) the printing step, (b) transfer of the pattern optically to a transparent flat sheet, and (c) formation of a negative of the pattern on a curved sheet forming the optical mask by projecting light through the flat sheet.

Title: Novel trifluoromethyl-phenyl compounds and a process for the manufacture thereof
IPC: A01P13/02
Filed: 1968-03-28
Abstract: 1,221,712. Trifluoro methyl phenyl acetic acid and derivatives. F. HOFFMANN-LA ROCHE & CO. A.G. 28 March, 1968 [30 March, 1967], No. 14968/68. Heading C2C. The invention comprises compounds of the Formula I wherein R represents a cyano, aminocarbonyl or carboxyl group the chlorine atom, being in the ortho or para position to either the trifluoromethyl or the -CH 2 R group. They are prepared by converting a benzyl halide of the Formula II wherein hal stands for a halogen atom, the chlorine atom being in the ortho or para position to either the trifluoromethyl or the -CH 2 R group, into the corresponding nitrile e.g. by reaction with an alkali metal cyanide, and, if desired, hydrolysing the nitrile to the corresponding amide or carboxylic acid. The compounds of Formula II are prepared by reacting a suitably chlorinated trifluoromethylbenzene with a halo-sulphonic acid and paraformaldehyde.

Abstract: 292,583. Forges et Ateliers de Constructions Electriques de Jeumont. June 23, 1927, [Convention date]. Alternating-current induction machines.-In a group comprising an induction motor and a cascaded commutator machine having displaceable brushes shunted bv a variable inductance for power factor and speed control, a relatively high power factor is obtained at low loads by providing an auxiliary winding in the slots of the stator winding of the commutator machine, the auxiliary winding being displaced from the main winding by a definite angle. In the form shown, the synchronous motor A is connected in series with the main stator winding B<1> to the brushes a, b of the commutator machine M. The auxiliary stator winding B<2> which, with the speed-adjusting inductance L, is shunted across the brushes, is displaced by an angle l with regard to the winding B<1>. Thus, the circuit a, B<2>, L, b constitutes in effect a secondary series machine with its brushes displaced by an angle # and operating as a self-excited generator superposed on the main machine. Specification 174,583 is referred to.

Title: Improvements in or relating to the drying of grain and apparatus therefore
IPC: F26B5/16
Filed: 1943-09-13
Abstract: 569,710. Drying systems. MORAN, T., and JONES, C. R. Sept. 13, 1943, No. 14993. [Class 34 (ii)] [Also in Group I] A process for drying grain consists in mixing therewith relatively small quantities ' of adsorbent materials such as silica gel or activated alumina, the adsorbent being '-removed from the grain after a relatively short time, then regenerated and again added to the grain, and so on in succession. The expression relatively small quantity" means a quantity which is small in comparison with that required to reduce the moisture content of the grain to any predetermined value in a given time, and " a relatively short time " means a period of time which is short in comparison with that required to reduce the moisture of a given quantity of the grain to any predetermined value. In one construction, shown diagrammatically in Fig 1, a grain drying plant comprises three bins a<1>, a2, a3, to which grain is fed by bucket or screw elevators b<1>, b<2>, b3, and to which adsorbent material is fed at d from a regenerator e. The contents of each bin passes over a series of sieves c<1>, c<2>, c<3>, which permit the adsorbent material to pass through them, such material being conveyed to the regenerator. The grain passes over the sieves to be fed to the next bin, the last sieve c<3> discharging into a bag h or like receptacle. The grain, before reaching the first bin a<1>,passes over a further sieve c which effects a preliminary cleaning. In a modification, Figs. 3 and 4, the grain is fed at t to a rotating drum u fitted with scoops v which carry the grain and adsorbent material up to drop them on to an inclined sieve w. The adsorbent material passes into the drum from regenerator 13 at 14 and is distributed over the grain by a screw conveyor x working in an apertured trough y. Sieve w permits the passage therethrough of the adsorbent mixture which is conveyed back to the regenerator by a screw conveyor 11. The grain falls back into the drum and eventually discharging into a bag 15. In a further modification, Fig. 2 (not shown), the grain and adsorbent material are fed to an inclined vibrating sieve arranged over a hopper, the latter serving to receive the adsorbent material which passes through the sieve and to deliver it to the regenerator. The grain passes down the sieve and is eventually discharged into bags or like receptacle. In the above processes any fine dust caused by the break-up of the adsorbent material, and which may adhere to the grain prior to its cleaning before milling, acts as an inhibitor to insect nests.
