Title: Improvements in explosives
IPC: C07C317/14
Filed: 1959-07-02
Abstract: The invention comprises dipicryl sulphone in the form of monoclinic crystals, and a process for the production of such crystals by crystallizing the sulphone from nitric acid, of concentration above 88%, at a temperature above 38 DEG C., and separating the crystals from the mother-liquor at a temperature above 38 DEG C.  The monoclinic form of dipicryl sulphone is free-flowing and has a higher bulk-density than the well-known orthorhombic form.  Furthermore, the monoclinic form has a greater explosive strength, and a higher thermal-stability.  In an example, a mixture of dipicryl sulphide, chromium trioxide and 95% nitric acid was heated at reflux temperature for half-hour, during which dipicryl sulphone was precipitated to give a suspension.  A small quantity of water was added to the suspension ; and it was cooled to 40 DEG C., and then filtered.  The solid sulphone was washed with hot water, and dried. The product consisted of dipyramidal crystals melting (with decomposition) at 335 DEG  C.-345 DEG  C., and having a bulk-density of 1,1 gram per cubic centimetre.

Abstract: 712,611. Windscreen cleaners. O'SHEI, W. E. Dec. 5, 1951 [Sept. 18, 1950], No. 22916/50. Class 138 (1) A windscreen wiper blade squeegee element, more particularly for wiping curved windscreens is constructed from one or more strips of rubber-like material of a width approximately twice the depth of the final squeegee element, said strip or strips being folded to a U-shaped form around a flexor which is positioned within the fold and is flexible at least in the plane of the folded element. In one construction, Fig. 1, the squeegee is formed by folding two strips, 1, 2, of rubber symmetrically about a flexible strip of metal 3 riveted at 4 to the strips. In the construction shown in Figs. 4 and 5 a central ply having an edge 6, is obtained by folding rubber strips 7 and 9 and a half width strip 8 about a flexible metal strip 5 connected by rivets 4 to the strips. The rear bulbous portion of the squeegee is held in channelled members 9a, 9b and 15 having inturned flanges 13, 14, and 17 respectively which retain the strips in folded positions. The members 9a, 9b, have end stops 16 to prevent longitudinal displacement therefrom of the squeegee. The arched portions of the channels permit upward flexing of the squeegee. The members 9a, 9b, are connected to a bridge piece 11 having an aperture 12 to receive the wiper arm. In operation the member 15 merely floats up and down with the squeegee. The plies of the squeegee may be stuck together except at their edges. If desired the flexible strip 5 may be of rectangular or circular cross-section strip rubber or thermo-plastic synthetic resin material. When made of rubber it may be stuck, vulcanized or otherwise secured to the rubber strips of the squeegee. In the case of a thermo-plastic strip the squeegee after formation may be heated to cause the strip 5 to adhere to the squeegee or to open through apertures therein to hold the rubber strips in their folded state. Other means of connecting the squeegee to a wiper arm are also disclosed. Specifications 544,841, 666,473, 666,474, 675,757, 679,540, 683,201, 712,603 and 712,610 are referred to.
