Patent GB-654521-A (GB)
Title: Manufacture of phenoxy-acetamidines
Filed: 1948-06-23
Abstract: Phenoxyacetamidines, useful as cardiac stimulants and of the general formula <FORM:0654521/IV (b)/1> (wherein the two R's occupy two of the positions 2, 3 and 4 and represent hydrogen or halogen atoms or methyl groups), are manufactured by reacting an imido-ether, thioimido-ether or thioamide, unsubstituted at the nitrogen, of the corresponding phenoxyacetic acids with ammonia, or the imido-ether or thioimido-ether with an ammonium salt, or a salt of the imido-ether or thioimido-ether with ammonia; or by reacting the corresponding nitriles with ammonia in the presence of hydrogen sulphide (which may be formed in the course of the reaction from an agent yielding it, such as carbon disulphide, phosphorus pentasulphide, an alkali sulphide, ammonium sulphide, iron sulphide or aluminium sulphide, if desired in the presence of a small quantity of water), or with an ammonium salt (especially of thiocyanic acid or an organic sulphonic acid), if desired in the presence of ammonia, or with sodamide; or by treating the corresponding amidoximes, unsubstituted at the nitrogen, with a reducing agent (e.g. hydrogen in the presence of Raney nickel). The products, if not obtained in the form of salts, may be converted into salts such as those of hydrohalic acids, sulphuric, phosphoric or nitric acid, or aliphatic, aromatic, alicyclic or araliphatic sulphonic acids (e.g. methane-, hydroxyethane-or p - toluene - sulphonic acid).  Examples describe the preparation of phenoxyacetamidine and its 4-chloro-, 2-, 3- and 4-methyl-, 2 : 4- and 3 : 4-dimethyl- and 3-methyl-4-chloro-derivatives.  Specification 476,611 is referred to.  Phenoxyacetonitriles employed as starting materials are obtainable by treating the appropriate phenol with chloroacetonitrile, or with chloroacetic acid or an ester or the amide thereof, followed by conversion of the product into the nitrile, e.g. by dehydration of the amide.  The conversion of certain of the nitriles into imido-ether and thioimido-ether hydrohalides is described in the examples.

IPC: G01N33/20
Filed: 1967-04-13
Abstract: 1,149,452. Sym - octahydroanthracene; anthracene. KOPPERS CO. Inc. 13 April, 1967 [22 April, 1966], No. 17105/67. Heading C5E. Sym-octahydroanthracene is produced by isomerizing sym - octahydrophenanthrene at 190-350‹ C. over a solid phase silica-alumina catalyst, e.g. 87% SiO 2 -13% Al 2 O 3 . The process may be conducted in the vapour or liquid phase, the pressure being varied as necessary, and the contact time being 0À01- 0À1 sees. or 10-180 minutes respectively. The equilibrium mixture of isomers produced may be cooled to precipitate most of the symoctahydroanthracene, which is separated, the residual mixture being recycled. The process may be used as one stage in an overall process for converting phenanthrene to anthracene. Phenanthrene is hydrogenated to sym-octahydrophenanthrene (e.g. using a nickel catalyst), the above isomerization carried out, and the sym-octahydroanthracene product then dehydrogenated to anthracene (e.g. using a Pd/carbon catalyst).

Title: Improved target locating and course steering means for use in the navigation of bomber and like aircraft
IPC: B64D1/04
Filed: 1942-12-03
Abstract: 560,706. Course-recording apparatus ; setting-out instruments for angles. MAY, W. J. Dec. 3, 1942, No. 17178. [Class 97 (ii)] [Also in Group XXI] Relates to course - recording apparatus for aircraft to enable a course to a target to be steered and to alter such course when about to make an approach for dropping bombs, flares, parachutists, &c. as well as to predetermine accurately points over the ground for releasing the bombs; flares, &c. when the target is obscured. The device comprising the invention consists of a transparent scale ruled by a number of lines representing altitudes and intersected by lines representing wind or ground speeds and having compass graduations to enable the scale to be set against a chart or course marked disc in a predetermined direction. As shown in Fig. 2, the transparent scale 17 is marked with longitudinal lines 18 representing altitudes, transverse lines 19 representing distances as indicated on part 10 of a course marked disc 7a, Fig. 1, such as is described in Specification 542,792. The scale is also provided with inclined lines 22 representing ground speeds. The end of the scale is provided with an aperture to enable it to be clamped between two rings, one of which, 28, is provided with compass graduations. Within the rings' a disc having an aperture 27 is provided. The course marked disc 7a is rotated in unison with a vector triangle apparatus and is provided with a direction pointer 9 which remains parallel to the direction bar of the vector triangle apparatus embodying vectors representing air, wind and ground speeds. In use, the scale is placed on the course marked disc 7a with the aperture over the target and the scale along the run-up course, as shown in Fig. 4. The bomb release point would then be that point on the chart indicated by the point on the mid-line x which is on the transverse plane of the point where the altitude line crosses the ground speed line on the scale. Fig. 5 shows a modification in which the scale is intended for dropping parachutists or flares, wind speed lines 34 replace the ground speed lines, and the scale is placed on the chart in the direction of the wind, as shown in Fig. 7. The point of dropping is determined as before, but a compensation for varying ground speeds is introduced in the shape of a disc 37 having concentric lines 38 representing ground speeds. Travelling with the wind the point of release is the part of the appropriate circle 38 most remote from the target. Against a head wind the point of release would be that part nearest the target and for other wind directions the release point will be where the appropriate circle 38 intersects a radial line parallel with the bearing of the course of the aircraft.

Title: Improvements in or relating to coating filaments
Inventor: WINDEBANK WILLIAM
IPC: C03C25/42
Filed: 1959-05-25
Abstract: <PICT:0896236/IV (c)/1> A method of coating a filament 5, e.g. a fibre thread, braid or tape, of glass or quartz, with an electrically conducting metal oxide, e.g. of Sn, Sb, In, Bi, or Cd, comprises passing the filament through a heated furnace limb 1 to preheat the filament, and then through a furnace limb 2 containing oxygen, where deposition of the oxide coating is effected, coating medium 9, which may be in liquid, gaseous, or vapour form, being introduced into the furnace 1, 2 at a point between the limbs, and the atmosphere in the limbs being moved in the same direction as the filament, e.g. by means of a suction pump connected to an outlet 4.  The medium 9, which may be an aqueous solution of a metal halide, e.g. of Sn or Sb, which at elevated temperatures in an oxygen-containing atmosphere deposits an oxide coating, enters the furnace via a heated limb 3 containing an air-operated spray gun 8.  The medium 9 may be an organo-metallic compound in alcohol, e.g. diphenyl tin dichloride or dibutyl tin acetate.  Baffles may protect the filament from direct impact of the medium 9, which may be intermittently delivered.  In an example in which boro-silicate glass is coated with an Sn-Sb chloride solution, the temperatures of the limbs, 1, 2, 3 are respectively 600 DEG C.-650 DEG C., 600 DEG C.-650 DEG C., and 400 DEG C.  The speed of passage of the filament through the apparatus may be automatically controlled in accordance with the resistivity of the applied coating (see Group XXXV).

Abstract: 1431905 Automatic control of bulk flow NATIONAL RESEARCH DEVELOPMENT CORP 13 April 1973 [19 April 1972] 18127/72 Heading G3R [Also in Division Gl ] The invention relates to optimizing the rate of feed of mixed objects e.g. potatoes and stones, to a sorting machine (such as that described in Specification 984232), responsive to their effect on a radiation beam. As shown schematically Fig. 3, the prior sorter comprises a feed conveyer-belt 11 from which material falls through a radiation beam directed on to a plurality of detectors 19, controlling deflectors according to the absorption of the object. According to this invention the detector outputs are also applied to a counter 29, through a comparator 27 with a threshold reference 28, so that a total count of all objects (potatoes and stones) is obtained. Since one object may obscure two detectors this count represents the cross-sectional (projected area) feed density rather than the number of objects. The count per unit time, may be displayed or compared at 32 with an optimum reference 33 to control the supply to the feed-conveyer 11 as by varying the speed-governor on the harvestortractor.  Details: (i) the system may operate by reflection instead of absorption (ii) the detector units may comprise a calcium tungstate luminophore and cooperating photo-electrons multiplier).
