Filed: 1972-03-28
Abstract: 1397611 Fire safety system K G SMOKE DISPERSAL Ltd 26 March 1973 [28 March 1972] 14354/72 Heading A5A A fire safety system for a building comprising accommodation units and communal access units includes a plurality of smoke detectors associated with the units, and means responsive to the detection of smoke in one of said units to admit air under pressure to said unit, to restrict the passage of smoke from that unit to other units, and to permit egress of smoke from that unit to the exterior of the building. The building shown in plan in Fig. 1 consists of accommodation units 1 surrounding a central service area comprising staircases 2, lifts 3 and vertical shafts 4, 5, 6, 7, and having access thereto via main corridors 8, 9, 10, 11 provided with self-closing fire doors 14-20 normally held open by electromagnetic locks. Each shaft 4, 5, 6, 7 is pressurised by a fan in the basement, is closed at the top of the building, includes vents opening into the staircases, and has a closable opening on each floor for the passage of air into one of 8, 9, 10 or 11. Smoke detectors are provided in main corridors 8-11, and also in subsidiary corridors 12 and 13 which have smoke vents 21, 22 in their external walls. If smoke is detected in 12 or 13, for example, the speed of the fans in shafts 4-7 increases to increase the air pressure on staircase 2; a vent from shaft 7 to floor level in corridor 9 opens; selfclosing fire-doors 14, 15 close; and vents 21, 22 open. Thus fresh air from 7 drives the smoke along corridors 12, 13 to vents 21, 22 and escapees can reach and use staircase 2 via doors 23, 24. The main corridors 8, 11 and half of 9 and 10 will be safely isloated from those parts of 9 and 10 between closed fire doors 14, 15 and even the latter parts will be usable by escapees heading for doors 23, 24 via fire doors 14, 15. In the modified building of Fig. 2 subsidiary corridors 12 are omitted and four smoke vents are provided in the outer walls of corridors 13. In the Fig. 3 building corridors 13 are also omitted and trunking is included to supply pressurised air to the accommodation units and to clear smoke from the main corridors; each accommodation unit is provided with a smoke vent in an external wall and smoke vents are also provided at the end of the trunking. Fig. 4 illustrates the application of the invention to a building of elongate rectangular floor plan with accommodation units on either side of a single central corridor. Reference is made to divisional Specification 1397612.

Title: Improvements in polymeric materials
IPC: C08G18/82
Filed: 1941-11-10
Abstract: Organic di-isocyanate modified polyesters or polyester-amides are given improved physical properties by mechanically working them whilst in a plastic condition.  The products have increased solubility in organic liquids and a decreased plasticity, while their solutions are progressively less viscous as they are made from polymers which have been subjected to progressively longer periods of working.  The mechanical working may be performed on a two-roll, differentially-geared rubber mill, at a temperature such that the polymer forms a running band on the slow-moving roll, or an internal-mixer may be used.  Working for 1/2 to 1 hour is usually sufficient, and temperatures of 60 DEG  C. and 85 DEG  C. are mentioned.  Other ingredients may be incorporated with the polymers during or after the working, and specified optional additions are carbon black, clay, asbestos, blanc fixe, whiting, lithopone, mica, ethanol, benzene, acetone, trichlorethylene, tetrachlorethylene, methyl ethyl ketone, natural or synthetic rubbers, vulcanized vegetable oils, white substitute, dark substitute, "Cumar" (Registered Trade Mark) resin, wood rosin, pitch, stearic acid, paraffin wax, oleic acid, lauric acid, tricresyl phosphate, dibutyl ammonium oleate, dibutyl phthalate, butylphthalyl butyl glycollate, N-alkyl-toluenesulphonamides, pigments, hydroquinone, N : N1-hexamethylene bis - ortho - hydroxybenzamide, and other anti-oxidants customarily used in rubber technology.

Patent GB-734812-A (GB)
Title: A process for separating 3- and 4-picoline from mixtures thereof
Filed: 1953-05-27
Abstract: 3- and 4-Picoline are separated from a mixture thereof which may contain 2 : 6-lutidine by adding water and sulphur dioxide to the mixture, fractionating it, collecting a fraction highly enriched in 3-picoline and a fraction highly enriched in 4-picoline, and removing water and sulphur dioxide from these fractions.  This removal may be effected (1) by distilling the fractions with a liquid which forms an azeotrope with water, e.g. benzene or toluene or (2) by adding NH3 or NaOH and an auxiliary liquid immiscible with water to the fractions (e.g. benzene or toluene), separating the picoline auxiliary liquid layer, and distilling it.  2 : 6-Lutidine, if present, may be separated from the mixture before adding the water and sulphur dioxide, or it may be separated from the isomer fractions.  In an example water and sulphur dioxide were added to a mixture of 3- and 4-picoline and the mixture distilled in a column of 18 theoretical plates, at a reflux ratio of 20 : 1 and at a head of column temperature of 97-98 DEG  C. whilst adding further sulphur dioxide to the mixture.  The first 35 per cent and the last 30 per cent of the distillate were separately collected and distilled with toluene to obtain 3-and 4-picoline respectively.  The rest of the distillate was recycled.  Specifications 580,048 and 585,108 are referred to.
