Title: Improvements in and relating to the drying of nylon 6 polymer
Inventor: ROWSON HENRY MAURICE
IPC: C08G69/46
Filed: 1960-09-15
Abstract: Nylon-6 polymer to be dried is introduced into a container 4 as a layer 12 above a gas-permeable support 8 and gas distributer 9 and is there fluidized by an inert gas, e.g. nitrogen, which is circulated in a closed circuit by a pump 1 and dried and heated at 2 and 3 respectively until the polymer has a water content of less than 0,075% by weight.  The gas is introduced into the circuit under superatmospheric pressure from a cylinder 6 and an inlet 15 for purging gas and a vent 14 are provided in the container.  A small quantity of hydrogen may be mixed with the gas and the mixture brought into contact with a platinum catalyst <PICT:0913542/IV(a)/1> to form water from the hydrogen and any molecular oxygen present in the circuit once in each cycle of the gas.
Patent GB-1112629-A (GB)
Title: A method and apparatus for treating attenuated fibres of heat-softened mineral material
IPC: F02M69/46
Filed: 1965-07-26
Abstract: Attenuated fibres of heat-softened mineral material are produced at one or more fibre-forming stations, have an aqueous binder applied to them at the fibre-forming station, and are collected on a moving foraminous collector.  Waste binder is continuously removed from the collector by recirculating wash water to which an alkaline detergent is added.  Some of this wash water is diverted for use in the binder composition, for which purpose its alkalinity is reduced, and it is mixed with binder ingredients.  In the embodiment described, the mineral material is glass and is formed into fibres in each of several rotary apparatus, from which the fibres are attenuated by and entrained in a blast of gas which carries them to a foraminous conveyor belt beneath which is a suction box.  The gas from this suction box is washed by a spray of water.  The return run of the conveyor belt is also washed by water.  The water from both of these washing operations together with water draining from the material on the conveyor and any binder and fibres entrained therein are passed through a screen to a tank where are added sufficient fresh water to maintain a constant volume and sufficient barium hydroxide to maintain a constant alkalinity.  The water in this tank is heated and recirculated by pumps to both washing points.  Part of it is also circulated to another tank, maintained at constant level by an overflow, where it is cooled.  It is drawn off as required from this tank to a mixing vessel where it is mixed with ammonium sulphate, to reduce the alkalinity and precipitate barium sulphate, and with ammonia, resin and oil to form the binder composition.  When there is more than one fibre-forming station, the rate of flow of binder to a binder applicator associated with each may be independently variable, to give a varying distribution of binder through the thickness of the product, e.g. to give a low binder content near each surface and a higher binder content in the middle of the mass.

Abstract: A grease composition consists of a major portion of a soap and a heavy hydrocarbon oil, preferably over 40 per cent of each, and a minor proportion of an organic oxygenated plasticizing agent consisting of pitch or a mixture of pitch and glycerol.  The pitch preferred is fatty acid pitch such as cottonseed oil pitch.  Soft stearine pitch and the residue obtained by distilling natural or synthetic fatty acids such as those obtained by the limited oxidation of paraffin wax may be used.  In the example, 51 1/2 lb. of steam-refined cylinder oil is heated to about 160 DEG  F. and 3 lb. of cottonseed oil pitch of m.pt. 86 DEG  F. added. After stirring, 21,9 lb. of free tallow acids and 20 lb. of prime tallow are added and a 40 B<\>ae. solution of NaOH containing 6,75 lb. of NaOH is added, the temperature being gradually raised from 160 to 225 DEG  F.
