Title: Improvements in hot blast stove installations
IPC: C21B7/00
Filed: 1926-04-07
Abstract: 275,289. Marks, E. C. R., (Freyn Engineering Co.). April 7, 1926. Hot-blast stoves; gas-heating furnaces.-In order to minimize choking of hot-blast stoves fired by washed blast-furnace gas, the gas is passed through a heater before admission to the stoves with the result that the dust which escapes the washer is deposited in the heater (whence it can readily be removed) and the flame temperature in the stoves is increased owing to the gas being dried in the heater. The heater comprises header chambers 31, 32 connected by relatively long narrow tubes through which the gas is passed and which are exposed to hot waste gas from the stoves or other units. The headers have sludge outlets 34 and manholes. A bye-pass for cutting out the washer and heater is provided, also a water seal to prevent backflow of gas when the blast furnace is shut down.
Patent GB-401334-A (GB)
Title: Improvements in or in connection with the use of electric fuses
IPC: H01H85/40
Filed: 1932-03-31
Abstract: 401,334. Fusible cut-outs. ABELL, R. H. 253F, Cromwell Road, Kensington, London. March 31, 1932. No. 9256. [Class 38 (i).] A fusible element enclosed in a frangible container is immersed in insulating liquid contained in an explosion pot, the pot having an opening for relief of pressure therein and the assembly being arranged so that when the fusible element blows. the frangible container is destroyed and the terminals are separated, the arc if not previously extinguished being thus drawn through the opening in the pot. As shewn in the Figure, the fusible element 1, enclosed in a frangible container 9, is held under the insulating liquid 2 between elements 5 and 6, the element 6 being under tension from the compressed spring 8. When the fuse blows the container 9 is destroyed and the spring 8 lifts element 6 to elongate the arc, the arc being withdrawn through the opening 4 so that, if not already extinguished, it is put out by the blast of oil and vapour deflected to the opening by baffle 10. The oil or other liquid 2 has access to the interior of the container 9 to provide a vapour producing substance which vaporises on the blowing of the fuse and causes the shattering of container 9. Specification 303,090, [Class 38 (i), Electric couplings &c.], is referred to. Reference has been directed by the Comptroller to Specification 397,234.

Title: Improvements in the cold separation of air
IPC: F25J3/04
Filed: 1954-03-30
Abstract: 747,298. Cold separation of air. BRITISH OXYGEN CO., Ltd. March 30, 1954 [April 9, 1953], No. 9260/54. Class 8(2). In an air rectification process for the production of liquid oxygen and wherein said oxygen is pumped and vaporized by heat exchange with a process stream e.g., warm incoming air, any cold so recovered which is in excess of the refrigeration requirements of the process is used to produce a reserve of liquid nitrogen which in turn is used to augment the supply of nitrogen reflux during periods when said recovered cold is less than the refrigeration requirements of the process. In operation the major portion of air at 170 atmospheres pressure in a duct 11 is cooled in an exchanger 13 by returning nitrogen gas, a portion thereof is further cooled by an expansion engine 21, a second portion is liquefied by returning nitrogen in an exchanger 27 and is then joined by the minor portion of incoming air after the latter has been cooled in an exchanger 33 through which liquid oxygen from the low pressure column 101, and a float chamber 117 is forced by a pump 131 at 2,700 p.s.i. to a container vehicle 139 in the gaseous phase and at atmospheric temperature. Cold wet air then traverses a recycle nitrogen liquefier 43, a scrubber 47 and a duct 53 to the high pressure column 57 at 75 p.s.i. Impure gaseous nitrogen therefrom passes through a duct 63 to a nitrogen rectifier 65 which discharges pure nitrogen gas through a heat exchanger 67 where it is warmed to atmos. pheric temperature and is compressed to about 120 p.s.i. by a compressor 68 driven by a variable speed motor 69 controlled by a pressure responsive device 70. The compressed nitrogen is then returned to the rectifier 65 as reflux through the exchanger 67, a duct 73, the nitrogen liquefier 43, a float chamber 74 and ducts 75, 81 an expansion valve 79 and a conventional automatic constant flow device comprising an orifice 95 controlled by an automatic valve 96. Liquid nitrogen from the liquefier in excess of the requirements of the rectifier 65 passes to a storage tank 87 from which product may be discharged through a valve 89. The tank 87 supplies the rectifier 65 when the supply through duct 75 falls below that required by the control device 95, 96, e.g. towards the completion of the oxygen container charging operation when due to the high pressure in duct 135 the heat exchanger 33 provides less refrigeration than in the initial and intermediate stages of charging. When no tank 139 is available liquid oxygen from column 101 is stored in a tank 125 or is withdrawn through a valved duct 127.

Title: Stabilisation of formaldehyde
Inventor: AINSWORTH WILLIAM FORSYTH
IPC: C07C47/058
Filed: 1961-03-14
Abstract: The invention comprises a stabilised formaldehyde solution comprising formaldehyde, a solvent therefor and 2-500 parts by weight per million calculated as basic nitrogen of one or more non-aromatic tertiary amines other than hexamine, and which is weakly acid, neutral or weakly basic corresponding to a free acid content up to 0.2% by weight of formic acid or a free base content by moles equivalent to up to 0.12 by weight of formic acid.  These compositions may be obtained by adding to the solution of formaldehyde the required quantity of a non-aromatic primary, secondary or tertiary amine, other than hexamine.  If primary or secondary amines are used they are converted by the formaldehyde to tertiary amines.  The "non-aromatic" amines are defined as amines in which no aromatic nucleus is directly linked to an amine group.  The amines which may be used include alkylamines, hydroxyalkylamines, cyclic amines and alkylene diamines.  The preferred ones are trimethylamine, triethylamine, diethanolamine, triethanolamine and 2-diethylaminoethanol.  In addition to the amines present there may be present other formaldehyde stabilising agents, for example metal sequestering agents such as hexamine.

Title: Apparatus for sealing ampoules and the like
IPC: C03B23/18
Filed: 1932-04-01
Abstract: 380,384. Sealing glass ampoules. MEYER, A., 50, Rue du Moulin, Puteaux, Seine, France. April 1, 1932, No. 9465. [Class 56.] A machine for sealing by fusion the necks of ampoules, such as are used for containing vaccines or other pharmaceutical liquids, comprises a number of gas burners mounted on a fixed base, an horizontal table which is rotated step by step, and a number of supports on the table for holding the ampoules, the supports being rotatable in relation to the table when in front of the burners. Nippers are also provided for gripping the neck of each ampoule and for drawing away the excess glass when the neck is fused. The machine comprises a base 1, Fig. 1, on which a number of burners 2 are mounted. A table 3 rotates on an axle 4 secured to the base and carries a number of holders 8 which are mounted on small rotatable discs 18. The discs are rotated, when in position beneath the burners 2, by means of pulleys 39. The table is rotated step by step by means of a lever 53 which engages pins 38 secured to the underside of the table. The lever is rocked by means of a cam 52 and a spring 60, and it also reciprocates a vertical rod 67 that slides through the axle 4. A vertical rod 74, secured to the rod 67, rocks a lever 76 which engages a sleeve 80 that slides over, and turns upon, the rod 67. The sleeve carries at its lower end an arm 83 which is engaged, in the lowest position of the sleeve, by one of a number of vertical pins 34 fixed to the table 3. The sleeve also carries at its upper end a nipper 87 comprising a bifurcated member 89, Fig. 4, and a movable member 92 which is pivoted on the member 89 and has an extended arm 90. In operation, a filled ampoule Z, inserted in a holder 8, first has its neck exposed to a jet of warm air from a tube 94 to evaporate any of the contained liquid that may be located in the part of the neck to be sealed. The ampoule is then carried around by the table until its neck is engaged by the nipper 87, the member 92 being held open by a stop 96. In the next movement of the table, a pin 34 engages and moves the arm 83 and the sleeve 80, and thus moves the nipper onwards. The member 92 moves away from the stop 96 and is closed by a spring 93. When the table comes to rest, the neck of the ampoule is heated at 99, Fig. 1, the ampoule being rotated by the pulley 39. After an interval, the rod 67 is raised, thus raising the nippers and drawing out the heated neck of the ampoule, the sealing being completed by the flame from the burner. Near the limit of the upward movement of the rod 67, the arm 83 becomes disengaged from the pin 34, and the sleeve 80 with the nipper is drawn backwards to its original position by a spring 84. In succeeding stopping positions of the table, the ampoule is allowed to cool. When sealing ampoules with short necks, the nipper is replaced by a horizontal plate which is pressed on to the heated neck to ensure sealing.

Title: Improvements in the production of pattern effects on textile materials made of or containing organic derivatives of cellulose
IPC: D06P5/12
Filed: 1931-03-31
Abstract: Coloured pattern effects on materials made of or containing water-insoluble cellulose esters and ethers are produced by locally resisting by means of oxidizing agents the fixation of leuco compounds of vat dyestuffs thereon or of vat dyestuffs in conjunction with reducing agents.  Yarn impregnated with an oxidizing agent and yarn not so impregnated may be incorporated in a fabric and the latter uniformly or locally treated with the colouring agent which may be applied by mechanical impregnation or otherwise and fixed on the unresisted portions by steaming or ageing.  The resists may contain suitable colouring matters a list of which is given in the Specification.  Mild oxidizing are preferably employed, e.g. sulphonated aromatic nitro compounds. Chlorates, chromates, and persulphates are specified.  The vat-dyestuffs of Specification 374,839 and 374,884 may be used and where the free leuco compounds have direct affinity for the material the proces of Specification 341,408 may be applied.  The cellulose ester materials may also be partially saponified to facilitate the fixation of the vat-dyestuff thereon.  In examples (1) A woven fabric of cellulose acetate is printed in a four-colour pattern, the printing pastes containing (a) sodium nitrobenzene-m-sulphonate without a resisting dyestuff and the same oxidizing agent in conjunction with the following dyestuffs respectively, (b) 1 : 4-dimethydiamino-anthraquinone, (c) 1 : 4 - diamino - anthraquinone, (d) benzeneazo-1-phenyl - 3 - methyl - 5 - pyrazolone and after steaming is over-printed with a paste containing Ciba Scarlet G. and Formosul; after steaming and oxidation a design in white, blue, heliotrope and yellow with a scarlet overprint showing on the ground only is obtained.  (2) The vat-dyestuff paste in (1) is padded instead of being printed.  (3) After printing with the four-colour pattern as in (1) the fabric is padded uniformly with a paste containing Caledon Jade Green and Formosul; a green ground is obtained.  (4) Cellulose acetate warp yarns dyed with 1 : 4-dimethyl diaminoanthraquinone are treated with sodium nitrobenzene-m-sulphonate, dried and woven into a fabric with a weft of plain cellulose acetate; the fabric is then printed with Ciba Scarlet G. and a reducing agent whereby a fabric having a blue warp and scarlet design on the weft only is obtained.  (5) 1 : 4-Diaminoanthraquinone is used instead of the 1 : 4-dimethyl derivative in (4) and the fabric padded uniformly instead of printed. Specification 306,611, [Class 15 (ii), Dyeing, Processes &c. for], also is referred to.  The Provisional Specification also describes a process in which a fabric is printed only with colouring matters which are dischargeable by reducing agents and then over-printing with a composition containing a vat-dyestuff and a reducing agent.
