Title: Improvements in mechanically operated furnaces for roasting pyrites or like ores
IPC: F27B1/20
Filed: 1921-06-27
Abstract: 167,464. Manufacturers de Produits Chimiques du Nord Etablissements Kuhlmann. Aug. 5, 1920, [Convention date]. Roasting-furnaces; charges, agitating; charging and discharging.-In a superposed hearth roasting furnace having rabble arms carried by a central rotary shaft, the rabble teeth are in the form of the mould board of a plough, the leading edge of a tooth being vertical and the following edge inclined at the angle of repose of the material. The teeth are set on the arm at an angle of 60‹ and are so spaced that the whole hearth is covered without any overlapping of the teeth. For the hearths on which the ore is moved from the centre outwards, the edges of the teeth in contact with the hearth may be curved concavely to the centre of the furnace. The Specification as open to inspection under Sect. 91 (3) (a) describes the complete furnace with the charging and discharging arrangements. The charging-hopper 9, Fig. 1 (Cancelled), is provided, beneath its outlet 10, with a swinging trough 15 suspended by links 17 from the casing 11 which is provided with a door 12, an outlet 14, and a slidable spring-pressed member 19, which abuts against the trough 15. A weighted member 22, pivoted at 23, is elevated and released by a revolving cam 26, and in falling on the member 19 operates the trough 15 and prevents the ore from jamming. The ore is discharged through the outlets 14 on to helical guides 27, 28, which are oppositely disposed and are secured to the shaft 4, the ore being thus deposited at regular intervals on the upper hearth 2. The peripheral ore openings 36 are helical and are designed to minimize the liberation of dust during the descent. An inclined plane 35, Fig. 8 (Cancelled), leads to each opening and a raised portion 37 is situated adjacent to the exit. A cleaning- hole 38 is provided. The central openings 39 may be provided with apertures on the shaft 4 for conducting ore to the lower hearths. The driving-wheel is provided with an annular receptacle 41 in which the ore is received previous to its discharge through peripheral apertures. The air for combustion is admitted at 8 and the hot gas passes through interconnecting passages 40. Fig. 7 (Cancelled) shows the manner in which a rabble tooth for a hearth on which the ore is moved from the centre outwards is cut from a solid block of wood, and also the special form of such a tooth. The angle at the leading edge of the tooth between a radial line and the tangent at that point to the curve of the tooth is 60‹, and the similar angle at other parts of the tooth is of constant value and substantially equal to 45‹. This subject-matter does not appear in the Specification as accepted.

Abstract: 387,909. Wrapping-machines. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(American Machine & Foundry Co.; 511, 5th Avenue, New York, U.S.A.) June 21, 1932, No. 17582. [Class 94 (i).] Articles are wrapped in transparent cellulosic sheet material, unwaxed paper, or other material not susceptible to sealing by heat alone, and adhesive is applied across the web during the wrapping operation, to seal the bottom seam of the finished package. The articles A arrive lengthwise on an inclined runway 28 and the foremost is transferred by a pusher 29 to position A<1> on a lifting table 30, then in the lower position 30<1>. The article carries with it a web from position W to position W<1>, the free end being turned up between the article and the table. The table rises about its pivot 32 and carries the article and wrapper to positions All, W<11>, the wrapper passing from the right-hand edge of the article past control rollers 45, 49. During the ascent, arms 39, carrying adhesive-applying rollers 42 move into the position shown in full lines to cause the rollers to apply adhesive to the wrapper. The arms 39 are actuated by rods 58 passing through apertured rotary studs 59, and move from the lower position shown in broken lines, where the roller at position 421 contacts with a drum 15 rotating in a receptacle 14 of adhesive, to the upper applying position. Rollers 47 press the wrapper against rubber blocks 48 on the table 30 and a knife 52 cooperates with a stationary ledger plate 54 to sever the wrapper. The action of the knife is such as to press the web into more efficient contact with the roller 42. The roller has salient paste applying portions corresponding to the spaces between the rubber blocks 48 to eliminate the possibility of mis-application of adhesive. The end folding is commenced by blades 55 mounted on the table 30 and adapted to close in upon the package. Resiliently mounted stationary folders 56 turn down the top flaps as the package approaches its upper position. On moving to position A<111> on a runway 31, folders 57 turn in the forward flaps, and the completed package is shown at position A<111>.

The values are held in a Read Only Store 10 addressed by the characters. Words on line 2 from, e.g. an OCR reader, a keyboard or a speech analyser, are fed to a Word Separation Detector determining the start and finish positions of the word, ot a numeric detector 6 deciding whether letters or numbers are received and to a gate 8 disabled if numbers are detected. The characters are serially fed to ROS 10 which produces the allotted values L N . The characters are also fed to a counter 18 which determines the position N of the character in the word. The values L E  are fed to a multiplier 12 and adder 14 to produce a sum Y = #L<SP>2</SP> N  which is held in register 16. The values L N  and the character position N are fed to multiplier 20 and adder 22 to produce a sum #L N N which is held in register 24. The character position values are fed to multiplier 30 and adder 32 to produce a sum R<SP>2</SP> = #N<SP>2</SP> which is held in register 34 and fed to a square root circuit to produce value R. The values R and Y are multiplied and are divided by the value #L N N and the result is fed to an Arcsecant table. The value Y and the angle produced from the Table 29 are then used as the two address to a two dimensional ROS to address a one bit location which contains '1' if the word supplied on line 2 is correct and a '0' if the wordis incorrect. If the allotted values are suitably chosen the area of ROS 38 addressed by words having a large probability of being incorrect contains many more zeros than ones and the probability of an incorrect word addressing a '1' location is reduced.
