Patent GB-1083081-A (GB)
Title: Granulation process
Inventor: MONKS IRENE HUDSON
IPC: B01J2/12
Filed: 1965-02-19
Abstract: Ammonium nitrate, or a composition comprising ammonium nitrate and at least one other component, is granulated in a process characterized in that the liquid phase required for granulation consists of a solution of ammonium nitrate in anhydrous liquid ammonia.  The granulation is preferably carried out at temperatures between - 10 DEG  and 40 DEG  C.  The liquid ammonia preferably contains at least 60% by weight ammonium nitrate in solution.  The liquid ammonia is subsequently removed by evaporation and excessive ingress of damp air is prevented.  The invention is particularly applicable to the granulation process of Specification 968,751.

Abstract: 728,825. Circlips. WALDES KOH-I-NOOR, Inc. March 25, 1952, No. 7612/52. Class 89(2). To enable circlips to be used in relatively deep grooves and yet to have a considerable projection they are made of soft metal and are assembled by deformation in the plastic range. The circlips have progressively decreasing section height from the mid-section to the free ends so that the circlip maintains circularity when deformed. The free ends are provided with lugs for engagement with a plier-like tool to affect assembly and removal. To ensure a tight non-slip fit of the circlip in its groove the groove is made with its front wall 33, Fig. 3, slightly inclined relatively to its straight rear wall 34, resulting in the clip wedging into its groove. In some forms the circlip has a surface 30c, Fig. 5, bevelled to suit the taper 33b of the grooves. In other forms parts of the circlip are bent as shown at 83, Fig. 17, to impart the wedging effect. Specifications 619,078, 623,584 and 674,514 are referred to.
