Patent GB-190311221-A (GB)
Title: Improved Process and Apparatus for Obtaining Nitrogen from Liquid Air.
Inventor: LIGHTFOOT THOMAS BELL
Filed: 1903-05-16
Granted: 1903-06-25
Abstract: 11,221. Lightfoot, T. B., [Ges. f³r Linde's Eismaschinen]. May 16. Nitrogen; oxygen.-Relates to the production of approximately-pure nitrogen by a modification of the process described in Specification No. 12,528, A.D. 1895, for the production of gases rich in oxygen by the fractional distillation of liquid air. The process consists in the rectification of the vapours from liquid air at atmospheric pressure by a liquid obtained by condensing these vapours. As the vapour of this liquid contains a smaller proportion of oxygen than the liquid itself, and therefore than the liquid-air vapours, oxygen is extracted from the liquid-air vapours, and a purer nitrogen vapour passes off. This vapour is recondensed and used in subsequent rectification, the effect of continuous working being that the liquid finally obtained yields vapour of the same purity as the vapours from which it was condensed. In one method of working, the air to be treated, after compression and cooling in suitable apparatus a, b, Fig. 1, is passed between the two tubes of the double coil c, and is there further cooled by the evaporation of another liquid in the inner passage final condensation taking place in a coil d. The impure liquid (containing 60 per cent. of oxygen) surrounding the coil d evaporates, and is partially rectified in the column g by liquid discharged from the coil d through the pipe f. Some of the impure liquid is drawn by an exhauster k through a coil i and the inner passage of the coil c, the effect of its evaporation being to condense some of the vapours at the top of the column l and also to cool the entering air in the coil c. The condensed liquid in the column l further rectifies the ascending vapour in this column. The purified vapour is cooled by the coil c as it flows out of the apparatus, and a mixture of oxygen and nitrogen is obtained in the vessel e. When it is desired to produce pure oxygen in addition to pure nitrogen, the apparatus shown in Fig. 2 is used. The air from the compressor a and cooler b flows through two cooling- coils m, n to two condensers d, o which discharge into the top of the column g. The nitrogen vapours escaping from the column l pass out through the casings of the coils m, n, and return through a compressor s, cooler t, and coil r to a condenser q from which the condensed liquid is discharged for rectifying purposes into the column l. The overflow liquid from the vessels e, p evaporates and passes out through the casing c of the coil n as pure oxygen. Liquid air for starting the process and making good losses during working is supplied through a pipe v.

Title: Improvements in Machines for Automatically Weighing Tea or the like.
Inventor: APJOHN JAMES HENRY
Filed: 1905-10-10
Granted: 1906-10-10
Abstract: 20,514. Apjohn, J. H. Oct. 10. Automatic -feed weighers; feeding- devices.-In apparatus in which tea orlike coherent material is delivered at a constant rate from a vibrating hopper, a special pivoted receptacle and platform are provided for feeding and dumping, and electric arrangements are provided for intermitting the vibration to suit the weighing. The vibration is conveyed from an electromotor 3, by an eccentric 4 of very small pitch, to an elastic framework 2, carrying the hopper. The tea, which is at a constant level in the hopper, falls into the pivoted receptacle 5, which is open at the bottom, and thence over a platform 7. The platform and the bottom of the receptacle are #-shaped and are separated by a small adjustable distance so that tea dribbles over the platform into the scale-pan. As more tea enters the pivoted receptacle than escapes over the platform, the receptacle rapidly fills and the major portion of the load may thus be made np quickly. By a flexible connexion and a lever 15 the receptacle when full is tipped into the position shown in dotted lines and closes the hopper. As the scalepan descends, contact is broken at 10, 11 and the motor is rapidly brought to rest by the wind vanes 14. The flow of tea ceases with the vibration. A lever 12 empties the scale-pan. The tilting of the receptacle and the discharge of the material from the scale-pan may be brought about by a packing-apparatus.
