Title: Apparatus for and method of determining flow
IPC: G01F1/66
Filed: 1972-02-10
Abstract: 1417115 Ultrasonic Doppler flow-meter HAWKER SIDDELEY DYNAMICS Ltd 8 Dec 1972 [9 Dec 1971 10 Feb 1972 28 April 1972] 57168/71 6313/72 and 19820/72 Heading H4D [Also in Division G4]  Simultaneous signals, obtained using an ultrasonic Doppler fluid flow meter and representing the received ultrasonic energy q in each of several discrete Doppler-shift frequency ranges, are separated by filtering, the separated signals are cyclically and sequentially sampled, and the samples are applied to a common signal channel for further processing and/or display. Each signal is associated with a respective flow velocity Vn. In the Fig. 6 blood-flowmeter embodiment, for producing a pseudo-threedimensional display in "rucked carpet" form (as shown in Fig. 2) on a long-persistence C.R.T. oscilloscope 11, the signals are sampled by multiplexer 18 whose output is multiplied separately at 21 by the sine and cosine of a preset angle #. The outputs from 21 are summed at 22, 23 with X and Y ramp waveforms from 13, 14 to provide the display deflection signals. The resulting display traces are staggered in both the X (time) and Y (velocity) directions. By varying # the apparent angle of view of the "ruck" can be varied. The ruck represents the occurrence of a heart pulse and its apparent height represents q. To suppress noise in or to enhance the display, the spot brightness or q signal may be reduced or blanked when q is of low amplitude. Electro-cardiograph or other marker signals may be added to the display via channel 20. In the Fig. 10 embodiment, for displaying an approximate profile of flow velocity V as a function of radial distance r from the centre of a duct of radius a, the q signal samples from multiplexer 38 are integrated at 39, and the integration result is summed at 41 with a fixed signal representing -a<SP>2</SP> and with a feedback signal representing r<SP>2</SP> from a squaring unit 42. The summation signal then represents r and provides the Y deflection for C.R.T. 44, the X deflection of which represents V and is synchronized with the multiplexer sampling. In further embodiments (a) a C.B.T. display of q against velocity V is formed and may be photographed, (b) each individual q signal, q n , is weighted by a factor proportional to V n  before multiplexing so that the multiplexer output represents momentum rather than velocity, the momentum signal being either integrated (Fig. 11, not shown) or used to form the "rucked carpet" type of display or passed to a computer or printer, or (c) a measure of the distance moved per blood pulse by a slug of blood in the aorta is obtained by determining during one pulse the highest value of V n  for which a q signal exists lasting more than a predetermined time (thereby eliminating short-duration spurious signals), determining during the next pulse the duration of the pulse (i.e. width of the "ruck"), and multiplying the duration by the determined V n  to give a signal which can be fed to chart recorder.

Title: The manufacture of aminoanthraquinone nitriles
IPC: C09B1/22
Filed: 1931-02-28
Abstract: Anthraquinone nitriles are made by heating 1 : 4-diaminoanthraquinone-2-sulphonic acid or a salt or substitution product thereof with an aqueous solution of a salt of hydrocyanic acid.  The sulpho group is split off.  In some cases 2 : 3-dinitriles are formed, in others 3- or 2-nitriles.  The 2-nitriles can be made from the 3-nitriles by further reaction with aqueous cyanides.  In examples, (1) 1-amino-4-hexahydroanilidoanthraquinone-2-sulphonic acid is heated with aqueous potassium cyanide under pressure and the 2-nitrile separated by means of its sulphate; on heating with acid in a sealed tube the nitrile yields a carboxylic acid identical with the product from 1-amino-4-bromoanthraquinone-2-carboxylic acid and hexahydroaniline; when saponified with sulphuric acid the nitrile yields the corresponding carboxylic acid amide which dyes acetate silk bright greenish-blue; (2) 1-amino-4-hexahydroanilidoanthraquinone-2-sulpho acid and potassium cyanide are heated as in (1) using smaller amounts of cyanide and a shorter time of heating and the product similarly isolated; it is probably 1-amino - 3 - cyano - 4 - hexahydroanilidoanthraquinone; the corresponding amide obtained by hydrolysis dyes acetate silk bluish-violet shades; by heating the 3-nitrile with potassium cyanide (aqueous) the 2-nitrile is obtained; (3) the 3-nitrile of (2) is obtained by refluxing instead of under pressure as in (2); (4) 1-amino-4-p-tolylaminoanthraquinone-2-sulphonic acid is heated with aqueous potassium cyanide under pressure; the product is identical with the 1-amino-2-cyano-4-p-tolylaminoanthraquinone of Specification 306,963, [Class 2 (iii), Dyes &c.]; (5) another nitrile is obtained from the starting materials in (4) using smaller amounts of cyanide; (6) 1-amino-2-cyano-4-anilidoanthraquinone is made from the 2-sulpho acid by heating with potassium cyanide with or without pressure; (7) 1-amino-4-n-butylaminoanthraquinone-2-sulphonic acid yields on heating with aqueous potassium cyanide the corresponding 2 : 3-dinitrile and the 2- or 3-nitrile which may be separated by means of their sulphates; (8) 1-amino-4-methylaminoanthraquinone-2-sulphonic acid is heated with aqueous potassium cyanide; by fractionating the product from sulphuric acid the corresponding 2 : 3-dicyano and 2-cyano compounds are obtained; (9) 1 : 4-diaminoanthraquinone-2-sulphonic acid is heated with sodium cyanide and the 2 : 3-dicyano body separated by means of its sulphate.  The Specification as open to inspection under Sect. 91 (3) (a) refers to the formation of intermediate products of unknown structure containing a nitrile group which products yield 2-nitriles on further heating with cyanide and to the formation of 1 : 4-diamino-2-cyanoanthraquinone from the corresponding 2-sulphonic acid.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements relating to the manufacture of transparent phosphor layer screens on glass substrates
Inventor: WOODCOCK STEWART
IPC: H01J9/22
Filed: 1959-02-25
Abstract: 866,150. Luminescent materials and screens; cathode-ray tubes. FERRANTI Ltd. Feb. 9, 1960 [Feb. 25, 1959], No. 6510/59. Class 39(1). Method of forming a layer of transparent phosphor material, comprising a base material and an activator material, on a glass substrate such as the face-plate of a C.R.T., includes the steps of forming a transparent layer of the base material on the glass substrate, forming ions of the activator material, and accelerating the ions sufficiently to cause them to impinge on the layer of base material with sufficient energy to diffuse or penetrate into the lattice sites of the base material. In the apparatus shown in the Figure the glass substrate 1 carrying a layer 2 of potassium magnesium fluoride is mounted in a chamber 3 which includes an electrically heated crucible 4 containing manganese chloride 5. An electron gun assembly 6 with associated anodes 7 is mounted in an extension 8 of the chamber 3, a collector electrode 9 being mounted on the opposite side of the chamber, and a grid electrode 10 extending across the chamber. The chamber 3 is evacuated and the crucible 4 is heated to cause the manganese chloride to fill the lower part of the chamber with manganese chloride vapour. The dissociated manganese ions are accelerated towards the layer 2 of potassium magnesium fluoride by the grid electrode 10 which is maintained at a negative potential with respect to the crucible 4 by the battery 11. The glass substrate so treated may be fitted on the glass screen of a C.R.T. Alternatively the transparent phosphor layer may be applied directly to the glass screen of a C.R.T. by applying a transparent layer of the phosphor base material to the screen of the C.R.T. and thereafter introducing a beam of ions of the activator material through the neck of the tube and causing the beam to diverge and strike the base material by means of an electrostatic lens mounted in the neck of the tube.

Title: Method of coating electric lamp envelopes
IPC: H01J9/20
Filed: 1957-02-28
Abstract: 813,732. Coating electric lamps internaly. SYLVANIA ELECTRIC PRODUCTS Inc. Feb. 28, 1957 [March 30, 1956(2)], No. 6800/57. Class 39(2) [Also in Group XL(a)] The inside walls of electric lamp envelopes are provided with either a lightdiffus:ing or phosphor coating by electrostatically precipitating thereon particles comprising a mechanical mixture of a light diffusing medium, or a phosphor, and an inert additive. The applied coating is subjected to a humid atmosphere, such as from a steam jet, to remove any residual charge on the particles and is subsequently dried. Alternatively in the case of a light-diffusing coating, removal of the slight residual charge may be effected by high temperature baking. An example of a light-diffusing medium that may be applied comprises an intimate mechanical mixture of wollastonite (calcium silicate) of a high degree of purity, with superfine alumina in the proportion by weight of sixteen to one. A colouring pigment may be added if required. Alternatively the coating mixture may comprise finely powdered bone ash (calcium phosphate) mixed with superfine alumina, also in the proportion of sixteen to one. Similarly, superfine silica may be employed as the inert additive. The coating apparatus comprises a rotatable bulb-supporting head 10 mounted on a shaft 12 driven by a motor 14 and coupling belt 20. Resilient fingers 36 engaging within the bulb neck retain the latter in position on the head 10, whilst a stationary feeder tube 40 extending upwardly through the head and connected by a tube 46 furnishes a supply of powder particles suspended in air and derived from a smoke-generator of known type. An insulating standard 22 on a table 24 supporting the rotatable head 10 supports a metal burner tube 26 provided with an end burner 28 and connected to a supply of combustible gaseous mixture through tube 30, and a metal plate 32 mounted on the insulating standard 22 is connected to the burner tube 26 and also to a source of high voltage D.C. supply. The bulb is first heated to a temperature of between 225‹ and 275‹F., and air is circulated through it to remove dirt and any moisture that may be liberated by the heat. An example of a phosphor coating that may be applied by the apparatus comprises tin-activated calcium zinc orthophosphate that has been ground in acetone for two hours, filtered and then dried at about 105‹C. Five hundred grams of this phosphor were mixed with about thirty grams of superfine alumina, this mixture being next placed in a smoke generator for application to the inside surface of an outer glass envelope for a 400 watt H.P.M.V. lamp. In another example manganese activated magnesium fluogermanate was ground in acetone-denatured ethyl alcohol and, after filtering and drying, was dry-blended with about 2 per cent of superfine silica. This mixture was employed in the electrostatic coating of a 100 watt H.P.M.V. lamp. The envelope used in each example was of soft lime glass heated to a temperature of between about 100‹-125‹C. to make it conductive during the electrostatic precipitation.

Abstract: 1408540 Controlling converters CONTRAVES AG 14 Feb 1974 [16 Feb 1973] 6862/74 Heading H2F [Also in Division H3] A circuit for producing a D.C. control signal for a controlled rectifier (e.g. in an A.C. to D.C. converter) comprises a device 11 for converting input signals to rectangular waves, negative feedback means R 7 , C 2 , 12 for feeding back the mean D.C. level and phase adjusting means R 1 , R 2 , R 3 , C 1  for bringing the output signal into phase with the input signal. As described, the input signal is derived from an engine driven A.C. power supply and the D.C. feedback reduces changes in timing of the zero crossing and thus maintains unity mark-space ratio of the rectangular waves when the engine is suddenly loaded. The phase adjuster compensates for phase shift due to R 7  and C 2 . The output wave is used to produce a sawtooth wave used for the control signal for the A.C.-D.C. converter.
