Title: Calculating-apparatus for the solution of triangles
IPC: G06G3/06
Filed: 1926-11-19
Abstract: 284,804. Barr & Stroud, Ltd., and French, J. W. Nov. 19, 1926. Plane trigonometry calculators.- Apparatus for solving a triangle by utilizing the relationship between the squares on the sides of a right-angled triangle, comprises a differential gear for summing the squares of the containing sides, conversion apparatus being employed to derive the squares and to extract the square root of the sum. Fig. 3 shows an apparatus for solving the usual gunnery triangle GHK, Fig. 1, the sides B and C of which are known. The value of the perpendicular E is obtained from B sin e by means of known mechanism such as that described in Specifications 1510/11 and 18546/14, [botb in Class 97 ..(i), Optical systems &c.], and being set up at 2, Fig. 3, is squared by conversion mechanism 3 that transsquared by conversion mechanism 3 that transmits the result to one element of a differential gear 7. The conversion mechanism may be as described in Specification 15294/14 or Specification 18546/14, [both in Class 97 (i). Optical systems &c.]. The second value, F, is derived from the sum or difference of C and D, the latter being obtained from B cos e, and is set up at 5 and its square transmitted to the gear 7. A third conversion gear 8 extracts the square root of the sum formed by the gear 7 and gives the result, A, at 9. In a second application of the invention the range B, Fig. 2, of an aircraft at K, the angle e and the distance C traversed by the craft in the time of flight of the shell are known and it is desired to flnd the future range A. As shown in Fig. 4, the values B cos e (= D) and B sin e (= E) are obtained at M and the former is added at 11 to the value C set at 13. The sum is then converted at 6 into its square and conveyed to the gear 7. The value E is similarly squared and added at 7 and is also continuously indicated at 17 in order that the constancy of this value may be checked by comparison with the initially-set marker 16.

Title: Improvements in submarine sound receivers
IPC: G01S1/72
Filed: 1920-10-16
Abstract: 152,616. Baron, H., (Signal Ges.). Oct. 16, 1920. Subaqueous audible signals.-The diaphragms and microphones of subaqueous sound signal receivers are separately tuned before coupling. The microphones are constructed, as described in Specification 14210/15, so as to have uniformly reproducible acoustic properties. For this purpose, the flanges k which grip the diaphragm a are ground on to each other, and the electrodes b, f and nut g are made with concave faces so as to grip the diaphragm and the back of the casing at their peripheries. The diaphragm a is preferably of bronze. The stem s of the electrode f serves for bolting the microphone as a whole to the main diaphragm m, the nut n being covered by a metal seal u. The receiver as a whole has two resonance frequencies depending on the natural frequencies of the diaphragm m and of the microphone and on the coupling between them; it is preferred to make the natural frequency of the diaphragm m higher than the signalling frequency and the natural frequency of the microphone higher still, the lower of the two resultant frequencies being made to coincide with the signalling frequency.
Patent GB-445208-A (GB)
Title: Process for the manufacture of agglomerates of carbonaceous material without addition of pitch
IPC: C10L5/08
Filed: 1934-10-13
Abstract: Carbonaceous materials subjected to globulation according to the process described in the parent Specification are pressed at about the temperature at which they issue from the oven and are retained in the moulds or passes for a period, found by tests for each coal, sufficiently long to allow cooling and solidifying to occur and to impart an internal crystalline structure similar to that of coal.  In a modification the globulation process is arrested at a moment shortly preceding or following that at which it is properly effected and a higher agglomerating pressure is applied for a shorter or longer time.  Modifications in the usual presses comprise an increase in the distance between the compressing and discharging members and in the number of cavities in the rotary table, also an increased stroke of compressing piston and depth of moulding cavity.  The moulds may be artificially cooled.  The agglomerates may be crushed and graded. The globulation process may be performed as described in Specification 445,207, [Group XII], by mixing a small proportion of globulable coal with other material which has been heated sufficiently to effect the globulation.  Specification 357,330, [Group XII], also is referred to.

Title: Improvements in or relating to absorption refrigerating apparatus
IPC: F25B15/10
Filed: 1937-10-27
Abstract: 496,323. Refrigerating. ELECTROLUX, Ltd. Oct. 27, 1937, No. 29343. Convention date, Dec. 31, 1936. [Class 29] Absorption systems.-In a continuous-cycle inert gas system a store of liquefied refrigerant is provided in a vessel 19, Fig. 1, thermally separated from the evaporator 14, and is delivered to the evaporator as soon as the vessel 19 receives heat from a warm part of the apparatus, such as the vapour expulsion pipe of the generator 10, during a starting period or when quick freezing or accelerated cooling is required. Heat may be transmitted to the vessel through a metal connecting member 24. This may have a wide aperture in it to receive a metal plug whereby heat conduction may be promoted or diminished by inserting or removing the plug. The storage vessel is filled by the flow of condensate thereto through a pipe 23 cooled by the fins of the condenser 12, and an overflow U-seal pipe 22, 21 connects its upper part with the end of the condenser, which is connected in the usual way to the evaporator by a U-pipe 13. Assuming the vessel to be full, as soon as the generator is heated, the vessel becomes warm and pressure is developed to force the contents through a U-pipe 20 into the pipe 13, and eventually to break the seal in pipe 21 and establish vapour communication between the vessel and the condenser. These assume the same vapour temperature and pressure and the vessel is gradually filled again by the flow of condensate through pipe 23. An alternative heating connection at 24 is described, Figs. 3, 5 (not shown), comprising an air jacket surrounding the hot vapour pipe and part of the vessel and provided with controllable openings to the outer air, whereby delivery of liquid to the evaporator may be regulated. The application of the storage vessel to a system with a two temperature evaporator and a double condenser is described, Fig. 2 (not shown), in which the storage vessel delivers to a jacket of a rectifier or to a junction vessel between the condenser parts. In another system, Fig. 6, heat is applied to vessel 19 through a pipe 53 conveying rich liquor raised from the absorber 16 by a pumping coil 52, which may be heated independently of the generator 10. The Specification as open to inspection under Sect. 91 comprises also the following : instead of a finned condenser a sinuous smooth coil bent into different superposed inclined planes may be used, the stretches being located so that no pipes are screened from the cooling air by those below. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in and relating to vat dyestuffs
IPC: C09B47/06
Filed: 1948-11-12
Abstract: Vat dyeings are obtained by treating the material in an alkaline vat with a cobalt phthalocyanine and a water-soluble reducing agent; the phthalocyanine may be substituted with sulphonic acid, sulphonamide, sulphinic acid, carboxylic acid, carboxylic amide, cyano, hydroxy, alkoxy, mercapto, alkylthio, nitro, amino, alkylamino or acylamino groups.  There may be used a mixture of a hydrophilic-substituted phthalocyanine and cobalt phthalocyanine itself or a non-hydrophilic substituted compound. A preferred mixture is one containing 15-40 per cent of cobalt phthalocyanine sulphonic acids, calculated as monosulphonic acid. Examples are given of the dyeing of cotton with cobalt phthalocyanines vatted with sodium hydrosulphite and caustic soda; after dyeing, the cotton is hung in the air to develop the colour.  A further example shows the similar treatment of wool, the dyestuff containing as substituent the trimethylamino-acetamido (quaternary chloride) group.  Other suitable dyestuffs are mentioned. Pyridine and bis- (hydroxyethyl) sulphide are specified as vat auxiliaries. The phthalocyanines may be obtained as described in Specification 704,310.  The Provisional Specification includes the subject-matter of the above specification and in addition contains further examples of the preparation of substituted cobalt phthalocyanines: (1) 4-nitrophthalic acid is heated with cobalt sulphate and the usual additions; the nitro groups are reduced to amino during vatting and the dyeings can be diazotized and coupled on the fibre; (2) 4-acetylaminophthalic acid and (3) 4-methoxyphthalic acid are heated with cobalt sulphate and the usual additions; (4) cobalt phthalocyanine is treated with sulphur chloride and aluminium chloride; (5) mononitro cobalt phthalocyanine is obtained by heating phthalic anhydride, 4-nitrophthalic acid and cobalt sulphate with the usual additions; the product is reduced to amino, diazotized, treated with potassium thiocyanate and hydrolysed to give monomercapto cobalt phthalocyanine; the di-, tri- and tetra-mercapto compounds are obtained similarly; (6) 4-phenylphthalic acid is heated with phthalimide - 4 - sulphomethylamide, cobalt sulphate and the usual additions; 4-methoxyphthalic acid may be used in place of the second reactant; (7) a mixture of anthraquinone-2-carboxylic 3\sv : 4\sv - dicyano - p - xenylamide, benzophenone, phthalonitrile and cobalt chloride is heated; (8) the chloride of 4-(trimethylamino-acetylamino)-phthalimide is heated with urea, benzamide, cobalt sulphate and ammonium salts.

Title: Improvements in or relating to power supply systems
Inventor: PEASE WILLIAM EDWARD
IPC: G05F1/32
Filed: 1956-09-27
Abstract: 827,750. Automatic voltage-control systems. STANDARD TELEPHONES AND CABLES Ltd. Sept. 27, 1956, No. 29500/56. Class 38 (4). Relates to circuits in which an A.C. source feeds a D.C. load through a transformer fed bridge-rectifier, the output voltage being stabilized for changes of load or input voltage. In one embodiment, in series with the primary winding of transformer 4 is the load winding 5 of a transductor 6 and an auxiliary bridge rectifier 7, the D.C. output of which operates the control winding of said transductor. Variation of the input A.C. voltage varies correctively the control current of transductor 6, but response is also achieved to change of output voltage by shunting rectifier 7 with the load winding 13 of a further transductor 14. Control winding 17, supplied by a reference D.C. source and control winding 15, energized by the load voltage, have opposing magnetization, rheostat 16 being adjusted so that magnetization from winding 15 just predominates with the minimum acceptable output voltage, i.e. minimum input voltage and maximum D.C. load. Reduction of load tending to increase the output voltage raises the magnetization of transductor 14 to reduce the impedance of winding 13, thus reducing control current in winding 12 and raising the impedance of winding 5 to oppose any change of output voltage. The reference voltage applied at terminals 18, 19 may be derived from the A.C. source by means of the circuits of Specification 745,796 or 754,325. Alternatively the circuit of Specification 792,654 may be substituted for control winding 17 of transductor 14 to provide directly a reference magnetization from the A.C. source, Fig. 2 (not shown). Specifications 599,018 and 665,335 also are referred to.
