Title: Tube flaring tool
IPC: B21D41/02
Filed: 1957-05-29
Abstract: 822,092. Tube expanders and flangers; spinning. IMPERIAL BRASS MANUFACTURING CO. May 29, 1957 [Aug. 10, 1956], No. 17026/57. Class 83 (4). A tube end is flared and burnished by means which may rotate and at the same time move axially of the tube to effect the flaring and may then rotate without moving axially to effect the burnishing. A chrome-plated, faceted flaring and burnishing cone 14 is rotated and moved towards a tube end 20 held in a clamp 13 of a frame 11. This is effected by rotation, by a handle 16, of a sleeve 12 threaded in the frame 11 and carrying the cone 14 which has limited axial movement relative to the sleeve 12. A square-sectioned extension 14c of the cone extends through a square-bore 12c of the sleeve, and a head 15a of a stud on said extension 14c is urged by a spring 17 to abut a shoulder 12d to limit outward movement of the cone 14 relative to the sleeve 12. Upon engagement of the cone 14 with the tube end 20, the cone 14 continues to rotate, but stops moving forward, the spring 17 being compressed, until a face 12f of the sleeve 12 abuts the cone. Thereafter the cone 14 moves forwards and rotates with the sleeve 12 to flare the tube end 20. Reverse rotation of the handle 16 then rotates the cone 14 and moves the sleeve 12 back, the spring 17 keeping the cone in contact with the now flared tube end to burnish it, until the sleeve shoulder 12d abuts the stud head 15a to move the cone 14 away from the flared tube end.

Patent GB-564833-A (GB)
Title: Improvements in processes for the production of pulp and other products from fibre-bearing vegetable materials
IPC: D21C1/00
Filed: 1942-12-02
Abstract: Cellulosic pulp suitable for the production of artificial fibres, explosives, plastics, or cellulose derivatives, is obtained by subjecting fibrous vegetable material to a continuous pretreatment with a weak alkaline solution or chlorine-containing solution, removing excess of solution and washing the pretreated material, and subjecting the washed material to an independent process of discontinuous digestion under pressure with an alkaline or acid solution.  The materials may be pretreated with a dilute caustic soda solution or with chlorine water, or a solution of a hypochlorite, chlorite or other chlorine compound having a bleaching or oxidising action.  A metal compound, which combines with organic matters and silica present with the cellulose, may be added to the pretreatment or digestion liquor or both.  Aluminium salts, hydroxide, or aluminates, may be used.  The insoluble silicates thus formed are readily separated from the black liquors.  The separation is facilitated by increasing the acidity of the liquor by adding sulphuric or sulphurous acid or an acid salt.  The liquor is passed to a recovery plant where the sodium salts are reduced to sulphide and then caustified.  The continuous pre-treatment may take place in towers or apparatus similar to wool-washing machines of the continuous type.  The pre-treatment liquor may be fresh caustic alkali solution, or black liquor from the digester.  Proteins, vitamins, and other products of food value or suitable as adhesives, may be obtained from the effluent liquor of the pre-treatment.  The digesters may have perforated plates or grids spaced from the bottom for supporting the charge of pre-treated material.  They may have tubes communicating the spaces above and below the grids.  High pressure is preferably used only in the first stages of the digestion.  Instead of an alkali digestion, the sulphite process may be used.  The pulp may be bleached with chlorine gas, chlorine water, hypochlorites, or chlorites, in one, two or more stages.  A treatment with alkali may be interposed between the bleaching stages.  The pulp may be subjected to washing with solutions of acids, e.g. nitric acid. In an example, cut cereal straw is passed continuously through a tank containing a 1 per cent warm caustic soda solution and through a tower where it is cooked for 30-40 minutes.  It is washed, pressed, and placed in a digester where it is heated under pressure with a 2-3 per cent caustic soda solution.  Seaweeds, grasses, straws, woods, and other cellulosic materials may be treated.  When seaweeds are treated, the pretreatment may be carried out in two or more stages starting with cold or hot water only, in order to remove inorganic salts, e.g. halogen salts and enable them to be isolated.

Title: Improvements in mechanical stokers
IPC: F23K3/10
Filed: 1920-06-26
Abstract: 160,110. Skelly, J. S. June 26, 1920. Stoking; air supply, regulating; grates. - An underfeed stoker comprises a retort to which fuel is fed by a plunger, together with two overfeed sections between the retort and the rear of the furnace, one of which receives the fuel from the retort and discharges it on to the other. In the stoker shown, fuel is fed by the plunger 14 to a retort 5, from the top of which it is discharged to an over-feed section formed of moving bars 7 alternating with stationary bars. A second over-feed section is formed of similar alternate moving bars 9; beyond this is a dumping-grate 11. The bars are reciprocated by rocker bars 24, 37 having arms 69, 71, to which are adjustably connected links 64, 70 operated from the mechanism that drives the plunger 14. By altering the points of connection of the links to the arms 69, 71, the rates of feed of fuel over each grate section may be adjusted so as to secure a correct distribution of the fuel. Air is supplied to a chamber 29 beneath the front grate section, thence through passages 34 in the bars to a chamber 32, whence it passes between the bars to the fire. Similar means deliver an independently-controlled air supply to the rear grate section. The forward ends of the bars in the front grate section are provided with openings through which air is delivered to the fuel issuing from the retort. To adapt the stoker to furnaces of varying sizes, the retort 5 and dumping-grate 11 are each made in sections, a number of which are used to make up the required width; whilst the use of fire-bars of appropriate length in the rear grate section in conjunction with fire-bars of standard length in the front section enables the total length of the stoker to be varied.
