Title: New disazo dyestuffs and their application
IPC: C09B31/02
Filed: 1931-09-30
Abstract: Disazo dyestuffs are manufactured by coupling a diazotized nitroamino compound of the benzene or naphthalene series, including derivatives thereof devoid of hydroxy, sulphonic or carboxylic groups, with a 2 : 5-dialkoxyaniline similarly devoid of hydroxy, sulphonic and carboxylic groups and capable of rediazotization after coupling, rediazotizing and coupling with amines of the benzene or naphthalene series devoid of hydroxy, carboxylic or sulphonic groups in the aryl nucleus and customarily used as end components.  The rediazotization should be performed at elevated temperatures, preferably 50-60 DEG C.; lower temperatures can be employed but in this case diazotization tends to be incomplete.  The products dye cellulose esters and ethers clear blue to violet shades.  The dyestuffs are applied in the form of an aqueous emulsion.  Examples describe the preparation of the dyestuffs: (1) p-nitroaniline --> 2 : 5-dimethoxyaniline --> m-phenylenediamine, which gives navy blue shades on cellulose acetate; if the m-phenylenediamine is replaced by a -naphthylamine the product gives a somewhat redder shade; (2) o-nitroaniline --> 2 : 5-dimethoxyaniline --> 4 - chloro - m - phenylenediamine, which dyes cellulose acetate violet shades; (3) p-chloro-o - nitroaniline --> 2 : 5-dimethoxyaniline --> 4-chloro-m-phenylenediamine, which dyes cellulose acetate violet shades; (4) p-nitroaniline --> 2 : 5-dimethoxyaniline --> m-aminodimethylaniline, which dyes cellulose acetate navy blue shades.  In an example of dyeing, the products are applied to cellulose acetate from a bath containing a naphthalene sulphonic acid-formaldehyde condensation product.  Other components specified are: first components: o-chloro-p-nitroaniline and 2 : 4-dinitroaniline; end components: m - toluylenediamine and ethyl-a -naphthylamine.

IPC: G21C1/22
Filed: 1964-07-02
Abstract: 1,035,864. Reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. June 25, 1965 [July 2, 1964], No. 27359/64. Heading G6C. In a fluidized-bed nuclear reactor the fluidizing gas passes vertically upwards through the fuel bed particles which counterflow downwards to the point of withdrawal at the bed base. To facilitate the fuel particle counterflow, horizontal zones are formed across the fuel mass where the particle agitation due to the gas is reduced and the particles flow downwards. Each of the horizontal zones is formed by vertical tubes, secured to an open framework. The tubes permit the free upwards flow of the fluidizing gas and thus prevent agitation, or bubbling, of the fuel particles at that level. Passage of the particles downwards through the tubes is prevented by wire screens of mesh smaller than fuel particles. Each tube may be provided with valve to adjust the gas flow.

Abstract: 634,457. Drilling-machines. FIFLDING & PLATT, Ltd., and PHILPOTTS, A. V. Oct. 13, 1947, No. 27408. [Class 83 (iii)] A power-driven drilling machine for deep drilling, e.g. drilling holes in platens required for plywood presses, comprises a support 5 in which the drill is free to rotate and which is disposed, prior to drilling, at a distance from the workpiece 17 greater than the depth of the hole to be drilled, and a second support 14 disposed adjacent the workpiece and incorporating rotational driving means for the drill, the latter means being arranged to discontinue the rotational drive should the drill jam in the workpiece. One or more drills 7 are mounted on a frame 1, Fig. 1, which has guiding bars for the supports 14, 15 and a further support 4 for the rear ends of the drills. The supports 4, 5, 14 are in the form of saddles provided with mountings for the drills, the spacing between the mountings in each saddle being adjustable when more than one drill is provided. The saddle 14 is provided with a driving head 12 for each drill, and such head comprises a hollow oil-filled casing 24, Fig. 3, which surrounds the drill shank 36 and has spring-pressed balls or rollers 29 housed in a hub 26 within the casing for firmly engaging flutes in the shank. Each hub 26 is driven to rotate the drill from an electric motor 19 through a chain drive 20 leading to a sprocket 48 keyed on a drive casing 42. Four spring- pressed balls 43 in the casing 42 engage recesses in a hollow spindle 41 which loosely surrounds the drill shank and is attached to the hub 26. Should the drill jam in the work, the spring- loaded balls 43 will slip. The support 5 is actuated to feed the drill by hydraulic mechanism, the feed motion being transmitted to each drill shank through four thrust pads 63, Fig. 4, engaging flutes in the shank and housed in the central part 62 of a bearing race 55 mounted in the support. By this means, the drill rotates as it is fed, and axial slip is permitted should the drill jam. The support 4 is linked to a ram (not shown) of the hydraulic feeding means for the support 5 so as to move therewith and comprises lubricant supply connections to each drill which is provided with an axial hole extending throughout its length. The drills are adjusted, initially, by a hand-lever 23 and, if desired, they may be withdrawn automatically after a selected drilling period for the removal of swarf. In a modification, the support 5 may be stationary, while the driving heads 12 are mounted on the work-support table for movement therewith in a horizontal plane, or, in the case of a vertical machine, in a vertical plane. In this case, the workpiece is fed on to axially-stationary drills. The Provisional Specification describes a modification of the drive means shown in Fig. 3, wherein the drive casing 42 is omitted and the sprocket 48, spindle 41, and casing 24 are connected together.

Abstract: 519,426. Repeating systems. STANDARD TELEPHONES & CABLES, Ltd., HODGSON, K. G., and JACOBSEN, B. B. Sept. 20, 1938, No. 27423. [Class 40 (iv)] 'In a multi-channel system in which each intermediate repeater is provided with frequency dependent networks 15, 16, 20, 21 in the line circuit and in the feed-back circuit of the amplifier 12, 13 to compensate the variable attenuation of a line section, so as to give uniform overall transmission for all the channels, the relative levels of the channels are adjusted at the terminal amplifier 11 at the transmitting end by means of a network 14 in the line circuit or 19 in the feed-back circuit or both in order to reduce the total noise interference. A restoring network 22 may be employed at the receiving end if necessary. In practice, the adjustment is made so as to reduce to a minimum the total noise in the channel which suffers most interference. It is then found that the noise generated in or picked up by the line is equal to the noise due to inter-modulation in one particular channel, generally a higher frequency channel, and that the total noise is substantially equal in all the channels. Auxiliary amplifiers may be inserted before the networks 15, 16. When thermal or valve noise is the dominant factor, the networks 15, 16 may be placed immediately after the amplifiers 11, 12 respectively. The amplifiers may be of the feed-back type described in Specification 371,887, [Group XL], the line networks being- employed in addition to the feed-back networkson account of stability requirements.

Abstract: 154,178. Frenier, A. B. Nov. 17, 1919, [Convention date]. Spray burners; oil supply and overflow fittings. -For the purpose of heating boilers or furnaces, liquid fuel is sprayed by air into a combustion chamber in the boiler within which chamber the flame is substantially confined, the air and oil supply being controlled by electrically operated means dependent upon the temperature either of the boiler or of the surrounding atmosphere. The burner comprises a combustion chamber 1, Figs. 4 and 5, into which projects a venturi tube 9 within which is a venturi fuel nozzle 11 supplied with liquid fuel from a float chamber 12 by pipes 12<d>, 11<k> and an annular passage 11<d> having openings 11<g> into the throat of the venturi tube 11. Air from a fan 5 driven by an electric motor passes by a pipe 3 to the burner and sprays the oil into the combustion chamber in which the spray is directed against a wedge-shaped part 1<b> and caused to circulate in the chamber being retained therein by inwardly extending flanges 1<a> while combustion is taking place. A gas pilot light 14 serves to ignite the fuel. Should the fuel not be ignited it will collect in the combustion chamber and overflow through a pipe 20b into a receptacle 20 suspended from an arm 17f which is caused by the weight of oil in the receptacle 20 to fall and close the valve 12<c>, cutting off the fuel supply by means of a safety switch and valve operating device 17 secured to the blower housing 4. An overflow pipe 20<c> from the float chamber 12 operates in a similar manner. A member 17<b> Fig. 9, at one end attached to the arm 17<f>, is also enabled, aided by the weight of the recep tacle, to throw a knife switch 18d open cutting off the current from the blower motor. When a thermostat B, Fig. 20, operates, owing to a drop in temperature, to close a circuit through the electrical device controlling the oil supply so as to promote a flow of oil a plug valve 14<c>, Fig. 19 controlling the gas supply to the pilot light which is kept burning by a screw-controlled by-pass 14<g>, is also opened and a full flame is produced the blower motor for the air supply being started.
