Title: Improvements in or relating to crucible furnaces
IPC: F27B14/14
Filed: 1929-06-17
Abstract: 332,701. Penicud, J. W. June 17, 1929. Tilting furnaces; covers; linings.-In a tilting concave furnace the lining is formed by two or more complete rings 16, 16<1> of refractory material, and the cover consists of a domed member 4 having plugged openings 21 for the insertion of fuel in the case of a coal-fired furnace, or of an ignition device where oil burners are used, the cover being held in position by a strap 6 and arms 61 adapted to coact with securing bolts, which may be of the hooked form shown in Fig. 1, or straight as shown in Fig. 2. A central opening in the cover accommodates a feed funnel 22 for the metal, and openings 24 in this are inclined downwards towards the interior so that the metal will not pass to the fuel space. The lining ring 16<1> is formed with an external pouring-tip 19, and with an internal notch 18 to take the external lip 17 of the crucible, and the pouring space is covered by a plate 40 to prevent access of fuel to the crucible. When the crucible is unlipped an internal lip is formed on the ring 16<1>. The lower part of the furnace is closed by a casing 7 having an inlet 8 for combustion air, and a discharge opening for split metal closed by a fusible plate 9. The crucible is supported on a cross-bar 12, and the fuel on two hinged grates 13, the free edges of which are supported by a pin 12<1> on the bar 12. The hinges are protected by the annulus 15. The furnace is tilted by a hand lever 25 pivoted to the furnace trunnion so that its inturned end can be positioned to engage notches 41 in a sector plate 37. Alternatively, the tilting axis may be in line with the pouring mouth, and in this case the tilting is effected by chain tackle. When the furnace is oil fired the casing 7 and grate 13 are unnecessary and an inlet conduit for the flame is fitted to the body of the furnace.

Title: Improvements in methods of and means for knitting fabric
IPC: D04B1/18
Filed: 1939-06-27
Abstract: 530,502. Knitted fabrics. BLANK, W. June 27, 1939, No. 18615. Drawings to Specification. [Class 74 (ii)] Relates to a puckered knitted fabric and to the method of knitting it on an 8-feeder dial machine fitted with welting devices on both beds. The alternate cylinder needles are removed. Two adjacent feeders knit elastic thread on cylinder needles only, while five adjacent feeders knit relatively inelastic yarn on dial needles only. One feeder knits inelastic yarn on both sets of needles. This feeder may be provided with a patterning wheel operative on cylinder needles only. The elastic component of the fabric is stretched while on the machine and the subsequent release of tension causes the fabric to pucker. The fabric is suitable for bathing costumes and garments for beach wear.

Title: Production of shrink-resistant wool
Inventor: GOLDBERG ALAN AUGUST
IPC: D06M11/50
Filed: 1964-05-07
Abstract: Wool and wool-containing materials in the form of continuous lengths, e.g. yarns, tops and woven and knitted fabrics, are shrink-proofed by wetting them out with an aqueous liquor containing (a) a wetting agent, e.g. an anionic or nonionic wetting agent, and (b) at least two shrink-resistance-imparting oxidising agents for wool which react with woollen fibres at markedly different rates and together produce a shrink-resistant effect thereon, immediately after wetting-out passing the wetted-out material through the nip between a pair of rollers to ensure that the material is uniformly impregnated with a controlled amount of the aqueous liquor and maintaining the controlled amount of liquor in contact with the material until at least a desired amount of each of the chemical reagents has reacted with the wool.  Metered quantities of aqueous solutions of each of the oxidising agents and wetting agent may be fed into the aqueous liquor to maintain the desired composition thereof, the quantities being correlated with the rate of pickup of liquor by the woollen materials being treated so that (a) the volume of liquor remains substantially constant and (b) complete renewal of liquor takes place in 1-15 minutes.  The oxidising agents may be an alkali metal permanganate and an alkali metal or calcium hypochlorite at pH values of 5-10, permonosulphuric acid and an alkali metal dichloroisocyanurate at pH values below 5, permonosulphuric acid and sodium or potassium hypochlorite or peracetic acid and sodium or potassium hypochlorite.  The pick-up of aqueous liquor at the nip may be 50 -250% by weight.  The material may be wetted with the aqueous liquor which may also contain magnesium sulphate either by immersion for 1-2 seconds or by spraying.  The treated material may subsequently be washed with water, passed through a dilute aqueous solution of a reducing agent, e.g. sodium sulphite or sodium bisulphite which may also contain formic acid, again washed with water and finally dried.
