Abstract: 627,539. Liquid fuel burners. LITTLE, H. C. March 7, 1947, No. 6487. Convention date, March 18, 1946. [Class 75(i)] A natural draft oil burner wherein a casing is provided in its top wall with a burner orifice through which a stream of fuel vapour and primary air formed in said casing is discharged, is provided with means for introducing secondary air into the fuel and air mixture stream as it passes through the orifice, such that portions of said secondary air are directed in the form of narrow jets diametrically through the fuel and air mixture stream. As shown a flow of fuel is maintained over the bottom 13 of chamber 7, vaporisation being commenced by an electrically heated coil 14, and continued by the heat radiated downwards from the ignited fuel mixture, primary air being drawn through openings 12. Attached to the top wall 8 of chamber 7 is a base ring 17 provided with a central passage 18 coterminous with orifice 9. Secondary air flows through passage 28 formed between flanges 17 and 24, and passes upwards inside a slightly conical cylinder 26. Wings 31, concave on their underside and extending radially upwards and inwards from the cylinder 26 project a portion of this air in the form of narrow jets across the main stream of fuel vapour and primary air. The base ring 17 has ribs 21 which serve to heat the secondary air stream. The deflector wings 31 are arranged in opposing pairs at an approximate angle of 24 degrees to the horizontal plane intersecting the vertical axis. The pressure area created over the centre of the main fuel vapour stream causes the flame to be diverted radially outwards into spaces 35, giving a well spread flame.

Title: Improvements in or relating to delay action or timing devices, particularly suitable for use in connection with electric control apparatus
IPC: H01H50/86
Filed: 1931-03-03
Abstract: 370,148. Electromagnetic switches ; interrupters and controllers. SCOTT, W. H., Gothic Works, Norwich. March 3, 1931, No. 6616. [Classes 38 (iii) and 38 (v).] An electromagnetic switch, which may operate as an interrupter, impulse transmitter, or as a reversing motor controller has a pivoted armature or a pair of mechanically interconnected armatures under the control of a pair of alternately-energized electromagnets the movements of the armature or armatures being retarded by short-circuited windings or conducting bands arranged on the cores and in inductive relation to the energizing windings, the armature or armatures controlling contacts for changing the conditions of an external circuit or circuits. As shown in Fig. 1, for a self-interrupting impulse transmitter the armature 3 is pivoted on a knife edge 4 on an upright member of a magnetic frame 4<1> which carries the cores 1, 2 of the energizing windings 5, 3. These windings surround heavy copper bands 6 on their cores 1, 2 and are energized alternately through contacts 8, 81 and 9, 91 completed alternately by the movements of the armature. Thus current impulses are produced in a coil 7 and the frequency of these impulses is reduced by the inductive action of the short-circuited bands 6. Adjustment of the frequency may be effected by varying the number and size of these bands or by varying a resistance 15 in the circuits of the electromagnet windings. The interrupter may be made self-starting on closure of the external supply circuit by the armature being lightly biased to one side by a spring 10. In the modification shown in Fig. 2 in which the movements of the armature are controlled by a manually-operated switch 11<1> to vary the direction of rotation of a lift &c. motor the coils 5 are in series with corresponding contactors 16, 17 and the contacts 8, 8<1> and 9, 91 are arranged so as to short-circuit the contactor which is out of action. The action of the retarding bands 6 on the electromagnets prevents a too-sudden reversal of current in the motor windings.

IPC: G03C7/34
Filed: 1944-04-13
Abstract: Disulphonamides of the general formula <FORM:0577387/IV/1> wherein positions ortho or para to the hydroxyl groups are reactive and A represents a divalent radicle of at least 8 carbon atoms and includes at least one benzene ring, are made by condensing an appropriate naphthalene sulphonyl chloride containing an acyloxy or oxycarbalkoxy (i.e. -O-COO Alkyl) group in the 1-position with an appropriate aromatic diamine and hydrolysing the acyloxy or oxycarbalkoxy group. The positions ortho or para to the hydroxyl groups may be unsubstituted or they may contain an atom or group, e.g. a chlorine or bromine atom or a sulphonic or carboxylic acid group, which does not inhibit dye-coupling reactions, and which is generally split off during such reactions.  Condensation may be effected in aqueous or non-aqueous media, e.g. in ether, acetone, acetic acid or dioxane, and a basic agent such as pyridine, a trialkylamine, triethanolamine or sodium carbonate, hydroxide or acetate, may be present.  In an example, 1 - oxycarbethoxynaphthalene - 2 - sulphonyl chloride is condensed with 4 : 41-diaminodiphenyl ether, 1 : 4-bis-(aminomethyl)-benzene, 1 : 5 - naphthylenediamine, 4 : 41 - diaminodi - phenylmethane, 4 : 41-diaminodiphenylmethane-3 : 31-dicarboxylic acid or p-bis-(b -aminoethyl)-benzene, and the product hydrolysed with an aqueous-alcoholic solution of potassium hydroxide.  Additional diamines specified are 2 : 21-, 2 : 41-and 4 : 41-diaminostilbenes and benzidine.  The nuclei of such diamines may be substituted by groups which do not enter into dye-coupling reactions, e.g. by hydrocarbon radicles (e.g. alkyl, aryl or aralkyl), halogen atoms or ether, nitro, hydroxy, amino, hydrocarbon-substituted amino, carboxy, nitrile, sulphonic, sulphone, sulphinic or sulphide groups.  Specifications 497,698, 544,189, 545,433, [Group XX], 554,302 and 556,858, [Group XX], are referred to.  Naphthalene sulphonyl chlorides used as starting materials above are prepared by treating 1-hydroxynaphthalene sulphonic acids, such as the 1 : 2- and 1 : 5-isomers, with a chloroformic ester or with an acylating agent, such as acetic anhydride or acetyl p  chloride, and treating the products with phosphorus pentachloride.
