Title: Improvements in and relating to ventilators for the ventilation of buildings
IPC: F04D27/02
Filed: 1968-01-26
Abstract: 1,218,530. Axial-flow fans. NORDISK VENTILATOR CO. A/S. Jan. 26, 1968 [May 24, 1967], No. 35861/70. Divided out of 1, 216, 703. Heading F1C. [Also in Division F4] A fan for ventilating buildings comprises a cylindrical intake duct 45 fitted coaxially around a cylindrical exhaust duct 44, air being impelled in opposite directions through the two ducts by respective impeller vanes 39, 38 driven by a common motor 37. A common damper for the two ducts 44, 45 comprises a pair of pivoted semi-cylindrical members 51 of the same diameter as the portions 49 of a cylindrical wall separating the two ducts. When the damper members 51 are pivoted into the fully open position in which they form a continuation of the wall portions 49, air is drawn from above the roof into the top of the intake duct 45 and discharged below the ceiling through twelve nozles 46, while air is withdrawn from the building through the exhaust duct 44. Guide vanes 68 allow independent control of the flow through the individual nozzles 46. The air is heated or cooled by passing warm or cold water through heat exchangers 47. When the damper members 51 are pivoted into the position in which their ends 52 abut, shaped edges 53 (56) abut the outer cylindrical wall 48. The ducts 44, 45 are then completely blocked in an upward direction, while an aperture 50 is then open to permit the air within the building to be recirculated. In the intermediate position shown, the damper members 51 permit both recirculation of air within the building and supply of fresh air from outside. Adjustment of the damper members 51 may be done manually or automatically in dependence on temperature or humidity.

Filed: 1937-12-30
Abstract: 507,081. Diaphragm air pumps. TAYLOR, J. T. Dec. 30, 1937, No. 36055. [Class 8 (i)] A diaphragm 4 acted on by suction from the inlet of an engine through a pipe 10 draws air into a chamber 15 and forces it through outlets 16, e.g. to clear the wind screen of a car ; when the diaphragm has nearly reached its limit of distension, the increasion vacuum applied through an aperture 11 withdraws a disc valve 7 from its seat 2 and allows air entry through an aperture 13, breaking the vacuum and allowing the diaphragm to be forced back by its elasticity. In a modification, the diaphragm actuates a suction breaking valve through a stem on the diaphragm carrying a stop coacting with a lever operating a cam which holds the valve. Additional blowers may be operated by connection to the suction space of the main blower.

Title: Process for the production of cast iron or steel
Inventor: CLEMENT CLAUDE
IPC: C21B13/00
Filed: 1961-10-09
Abstract: Cast iron or steel is produced from an iron ore or oxide by introducing natural gas or methane with the iron ore or oxide, preferably powdered and suspended therein, directly into a bath of molten iron containing dissolved carbon, e.g. cast iron or steel with 2-4% carbon at 1200-1300 DEG  C., below the molten slag layer, e.g. 10 to 100 cms. below the molten iron surface, and burning the escaping reducing gases H2 and CO by means of oxygen introduced above the surface of the molten iron, preferably air supplied at the top surface of the slag.  The quantity of natural gas or methane is at least sufficient to supply to the molten iron the amount of carbon being consumed in the ore reduction, i.e. one molecule of CH4 per atom of O combined with Fe.  A slag of sufficient thickness may be formed by the reaction of impurities in the ore with a flux, or if pure iron oxide is processed, by adding one or more easily melting ores.  The slag and cast iron or steel may be withdrawn continuously or intermittently.  Any unburnt CO and H2 gases may be used in a prereduction stage.

Abstract: 1298413 Spinning apparatus IMPERIAL CHEMICAL INDUSTRIES Ltd 4 Aug 1971 [4 Aug 1970] 37582/70 Heading B5B Spinning apparatus comprises a spinning pack 1 and a spinneret 2 with a face exposed to ambient atmosphere and associated in close proximity to, or contiguity therewith, a shield 7, disposed parallel to said face of substantially the same size and shape as the exposed spinneret face, and through an aperture or apertures in which shield the extruded filaments pass, so that in the melt-spinning of fibre-forming polymers through a plurality of such spinning packs, variation between the rates of loss of heat from the exposed faces of the various spinnerets is minimized, since at least the faces of said shields directed towards said exposed spinneret faces are maintained at substantially constant and substantially identical temperatures as a result of being supplied with a source of heat in common with that serving to maintain the spinnerets at the desired temperature. The source of heat is suitably a heattransfer fluid. Thus spinning pack 1 is heated by vapour jacket 3, and the pack and vapour jacket are insulated by a muff 4, an insulating lid 5 and insulation 6. The shield temperature should differ from that of the heat transfer medium by not more than 50‹ C, especially no more than 10‹ C. The shield is suitably constructed of material of high thermal conductivity e.g. copper, aluminium or silver, and may be movable or removable to permit wiping of the spinneret face. That face of the shield directed towards the spinneret face may be polished, and is suitably chrome plated. The other side of the shield 8 may be provided with a layer of low thermal conductivity e.g. asbestos, or a chamber containing air or which is evacuated. A shield may be in more than one part. Thus, where the pattern of spinneret holes constitutes a straight line the shield may be in two parts one each side of the straight line, the two parts of the shield delineating a narrow band free from shielding and in which the spinneret holes are situated. Figure 2 shows a view from below the spinneret of Fig. 1.
