Title: Improvements in or relating to furnaces
IPC: F23K3/10
Filed: 1933-12-01
Abstract: 429,836. Furnace grates; underfeed stokers. WATERLOW, E. O., The Limes, West Molesey, Surrey. Dec. 1, 1933, No. 33851. [Class 51 (i)] A furnace grate comprises a number of transverse grate sections or bars adapted to be angularly movable about substantially vertical axes to enable the air spaces between the bars to be cleaned, the continuity of the grate surface being preserved during the angular movement. As applied to a furnace of the underfeed type having a fuel retort 6 disposed to one side of the flue between a relatively narrow grate 12 and a main grate 13, the bars of the main grate are supported at one end on a longitudinal edge 16 of the retort and at the other end on a reciprocable rod 18. The end bars 20 of the main grate and if desired intermediate bars also, are pivoted at 21 to the retort and are actuated by the engagement therewith of stops 22 on the rod 18, the angular movement producing a shearing action between adjacent bars. The rod 18 is reciprocated from a fuel feeding ram, (not shown), operating in a casing 7 by means of a rocking lever 24 coupled to a rod 27 having spaced collars 29 adapted to be moved by an arm 28 projecting from the ram. The amount of movement may be varied by adjusting the collars 29 or by hanging U-shaped washers on the rod 27. Beyond the grate 13 is a clinker bed comprising plates 33<a> over which reciprocate plates 32 of triangular form in cross section carried by a plate 33 which extends through the front of the furnace for manual operation by means of a lever 34 or for connection with the fuel feeding ram. Ash and clinker fed forwardly by the plates 32 is discharged through a door 31 horizontally pivoted at its upper edge to a larger vertically pivoted door 30. Fuel fed to the retort by the reciprocating ram or by other means is distributed by reciprocating elements 8 driven from the ram by a rod 9. The lower surface of each element is shaped to fit the retort and the upper surface at the front is obliquely inclined and is of substantially triangular shape in plane having a rounded apex disposed to one side of the longitudinal centre of the retort and at the rear is relatively steeply inclined. The effect of the elements is to feed the fuel upwardly and over the grate susbtantially at right angles to the retort. Several retorts and grates may be included in a single furnace.

Title: Process for the production of condensation products from 1:8-naphthosultone, and theresulting products
IPC: C07D327/02
Filed: 1945-12-18
Abstract: 4 - Halogenmethyl - 1 : 8 - naphthosultones are made by treating naphthosultone with formaldehyde and a halogen hydracid in presence of a condensing agent, e.g. in glacial acetic acid or in formic acid, in the presence of zinc chloride.  The halogenmethyl bodies may be (1) converted to 4-methyl derivatives by reduction; (2) treated with a hydrolysing agent to convert to 4-hydroxymethyl bodies by replacement of the halogen by hydroxy; (3) treated with ammonia or a primary or secondary amine to replace the halogen by amino or substituted amino; (4) treated with salts of organic sulphinic acids to replace the halogen by a sulphonyl group; (5) treated with an aromatic or substituted aromatic compound by a Friedel-Craft reaction to replace halogen by an aromatic or substituted aromatic group; (6) treated with an alkali sulphite so as to replace the halogen atom by a sulphonic acid group.  Any of the above reaction products may be converted to salts of 1-hydroxynaphthalene-8-sulphonic acids by boiling with dilute alkalies or ammonia.  Examples describe (1) the formation of 4-chloromethyl- and 4-bromomethylnaphthosultone from naphthosultone, paraformaldehyde and zinc chloride in glacial acetic acid, and hydrochloric or hydrobromic acid gas, and also the reaction of 4-chlormethylnaphthosultone with (2) hydrochloric acid, and zinc dust in alcohol to give 4-methyl-1,8-naphthosultone, which is heated with caustic soda solution to give 4 - methyl - 1 - hydroxynaphthalene - 8 - sulphonic acid; (3) with water to give 4-methylol-1.8-naphthosultone; (4) sodium p-toluenesulphinate in water to give a sulphone; (5) benzene (or toluene, xylene, pseudocumene, mesitylene, or anisole) in presence of aluminium chloride, to give the corresponding 4-benzyl (or substituted benzyl body), which is boiled with caustic potash solution to give the potassium salt of the 4-benzyl (or substituted benzyl)-1-hydroxynaphthalene - 8 - sulphonic acids; (6) with methyl salicylate in presence of aluminium chloride and trichlorbenzene to give 4-(41-hydroxy - 31 - carbomethoxy) - benzyl - 1.8 - naphthosultone, which is heated with caustic potash solution to give potassium salt of the sulphonic acid; (7) phenol, to give the 4-(41-hydroxy)-benzyl-1.8-naphthosultone, which is boiled with caustic potash solution; (8) piperidine, to give the 4-piperidinomethyl body, or dimethylamine to give the 4-dimethylamino body; (9) sodium sulphite solution to give sodium naphthosultone-4-o -methanesulphonate.

Abstract: 921,209. Gyratory crushers. ARBRA VERKSTADS A.B. Sept. 25, 1961 [Sept. 24, 1960 (3)], No. 34320/61. Class 59. [Also in Groups XXIX and XXXII] In a gyratory crusher, the inner crushing member 3 is supported for axial movement by a plunger 11 enlarged at its lower end to form an hydraulically -actuated piston 12 slidable in a cylinder 13b supplied at inlet 16 with pressurized liquid. The inlet 16 is connected via a shut-off valve and hand pump to a graduated tank containing liquid which may be pumped from the tank to the cylinder 13b or returned to the tank from the cylinder to raise or lower the member 3 to vary the crushing space, the liquid level in the tank indicating the variation made. The inlet 16 is also connected to a safety device 20, Fig. 2, comprising a differential valve 25 loaded on its underside by the liquid pressure and on the top by a constant air pressure. Uncrushable objects larger than the normal crushing space are thus allowed to pass through the crusher by pushing down the member 3 to temporarily increase the space; excess liquid being forced momentarily into the cylinder 23 of the device 20. The crushing pressure may be controlled by the air pressure in the cylinder 20. Air bled from the cylinder 20 through a throttle 34 and pipe 36 may be utilized to flush off stone dust in the crusher. To obviate the piston 12 striking the bottom of the cylinder an increasing throttling action takes place between a tapered projection 18 and a recess 17 in the piston so that increasing braking action is provided as the piston moves downwards.

Abstract: 605,253. Electric resonators. SPERRY GYROSCOPE CO., Inc. Dec. 21, 1945, No. 34771. Convention date, Dec. 21, 1944. [Class 40 (viii)] The inner conductor of a concentric trans-, mission line is supported by an annular disc including an electrical conductor, continuous between the two boundaries of the annulus but covering only part of its area, and forming an oscillatory circuit which is resonant at a particular frequency in the normal operational frequency band of the line. The bead will then not produce undesirable reflections in the operation of the line. For example, the inner conductor 12 of a line 10 may be supported by thin metal discs 13 and 14 in which a slot has been cut so that they each form a resonant circuit. The length of the slot is roughly inversely proportional to the resonant frequency and for low'frequencies a spiral slot may be required. Alternatively, as shown in Fig. 5, the slot may end in holes 20, which may be countersunk, which give a lower resonant frequency to the slot. The construction of Fig. 9 is suitable for still lower frequencies and comprises two conducting rings 25 and 26 forming a capacity, spaced by dielectric rings 28 and 29 and connected by a spirally wound conducting wire 30. An impedance transformer may be formed with these discs as shown in Fig. 15. The discs are adjusted by screws 48 and 49 extending through slots in the line. Disc 44 is rotated and disc 45 is moved axially along the inner conductor.
