In the production of granules, e.g. of fertilizer, from a solution, slurry or melt by contacting droplets of the solution, slurry or melt in tower 1 with hot or cold gas supplied through ducts 5, fine granules separated from the product are introduced into the upper end of the tower and evenly distributed over its cross-sectional area by vibrating screen 2, while the solution. slurry or melt is projected through sprayers 3, 3' onto the fines as they fall down the tower. The granules which collect at the base of the tower are carried pneumatically up pipe 9 to separator 10 from which the gas is discharged by blower 7. The separated granules are sized on sieve 14, the marketable product being withdrawn by screwconveyor 16, and the fines being returned to tower 1 through pipe 18. The hot or cold gas supplied through ducts 5 enters the tower through regularly -disposed openings 6 at the bottom of annular chamber 4. Additional hot or cold gas may be injected through pipe 21. Sprayers 3, 3' may be mounted on sliding supports. Reference is used to cooling melts of urea, evaporating concentrated solutions of ammonium nitrate, and drying slurries of complex fertilizers obtained by the nitrosulphuric, nitrophosphoric and nitro carbonic processes.

Abstract: 1366619 Blasting apparatus comprising D.C. to D.C. conversion BENDIX CORP 15 Nov 1972 [23 Nov 1971] 52783/72 Headings H2H and H2F A blasting machine for detonating blasting caps or squibs connected to terminals 190 comprises a capacitor 153 which is charged from a D.C. supply 140 by way of a solid state oscillator 1 and a transformer 150 a pulse generator 5 having a gaseous breakdown device 170 being provided to generate a plurality of pulses when the capacitor 153 has been charged to a first predetermined level, the pulses being fed to a triggered gaseous breakdown device 180, breakdown of which allows the capacitor 153 to discharge and fire the blasting caps, the machine being provided with a further gaseous breakdown device 160 having a somewhat higher breakdown value than that of the device 170 so that the charge acquired by the capacitor 153 is prevented from exceeding a second predetermined level, higher than the first predetermined level. In the OFF position a switch 9 has a lower contact by means of which the capacitor 153 is discharged when the machine is switched off. A manually operated switch 181 may be provided whereby triggering of the device 180 by the trigger circuit 5 may be controlled manually and the switch 181 may be provided with a lower contact which is in series with the lower contact of the switch 9. When the switch 9 is in the ON position the short circuit is removed from the capacitor 153 and the battery 140 is connected to the oscillator 1. Transistor 121 then conducts with the subsequent conduction of transistor 103 whereupon current flows in the primary winding 101 of transformer 150. With current flowing in winding 101 the transistor 121 gradually returns to the non-conductive state, at which the transistor 103 becomes non-conductive. The energy in the winding 101 then discharges through diodes 104, 106, 110 and resistors 111, 112 thus inducing an output pulse in the secondary winding 151 which charges the capacitor 153 by way of a diode 152.

Abstract: 1381615 Grinding SOC NOUVELLE DE ROULEMENTS 16 Nov 1972 [27 Dec 1971] 52956/72 Heading B3D  Means for feeding a workpiece against a grinding wheel on a centreless grinder comprises a cylinder housing two pistons separated by resilient means and connected for limited maximum separation by a member telescoping in one of them, one piston carrying a radial workpiece support and the other being connected to feed control means, the resilient means enabling the force transmitted between the pistons to be varied. The workpiece 20, an annulus as shown, is fed against the wheel 4 by a support shoe 1, being additionally supported by a magnetic plate 3 and a shoe 2. The shoe 1 is pivoted to a piston 5 having secured to it a connecting member 7. The member 7 slides within a second piston 6, the maximum separation between the pistons being determined by stops 15. The space 19 between the pistons is connected to a variable pressure compressed air source.  To advance the workpiece, the piston 6 is advanced, the cushion of air between the pistons maintaining them at their maximum separation so that the piston 5 also advances when the latter presses the workpiece against the wheel. Further advance of the piston 6 to the limit of stop 10 brings stops 15 clear of the member 7 so that the piston 5 is influenced only by the air cushion in applying grinding pressure. The latter is arranged to be low initially and to increase as grinding progresses. Forward movement of the piston 5 is limited by an eccentric 8 on a shaft 23 running in slots 22 permitting external adjustment. The member 7  abuts the eccentric with depression of a slideable feeler 28. This permits control means to allow a dwell period for smoothing and then effect withdrawal of the shoe 1.
