IPC: C07C51/56
Filed: 1964-12-04
Abstract: The three compounds of formula <FORM:1088774/C3/1> in which the methyl groups and the anhydride group connecting two benzene rings are attached to the 3- and 4-positions of these rings may be used as curing agents for epoxy resins.  An example (Example V) is given of the use of a mixture of the three compounds in curing an epoxy resin.ALSO:A benzophenone-3 or 4-methyl tricarboxylic acid having the general formula <FORM:1088774/C2/1> in which the methyl and carboxylic groups occupy the 3 and 4 positions of the benzene ring indicated is made by oxidizing 3,4,31,41-tetramethylbenzophenone in the presence of an oxidizing agent and a solvent at 50-150 DEG  C. for 0.1-10 hrs. If the product mixture is heated at 150-250 DEG  C. for 0.5-24 hrs. a mixture of benzophenone-4-methyl-3,31,41-tricarboxyli anhydride and benzophenone-3-methyl-4,31,41 -tricarboxylic anhydride of formula <FORM:1088774/C2/2> is obtained.  By reacting these anhydrides with acetic anhydride the corresponding mixed anhydrides of formula <FORM:1088774/C2/3> are obtained and on further heating trianhydrides of the formula <FORM:1088774/C2/4> are obtained.  In all the derivatives the methyl group and the anhydride group in the second benzene ring are in either of the 3 and 4-positions.

Title: Arming mechanism for a projectile fuse
IPC: F42C15/285
Filed: 1968-10-17
Abstract: 1,249,875. Projectile fuzes. HONEYWELL Inc. 17 Oct., 1968 [30 Oct., 1967], No. 49388/68. Heading F3A. An arming mechanism for a spinning projectile comprises a housing 12 with a cavity 20 containing both a liquid and an arming member 14 which has buoyancy in respect of the liquid, and, by virtue of liquid pressure arising as a consequence of centrifugal force is movable perpendicularly towards the spin axis against the force of biasing means 15. The arming member comprises a hollow piston provided with a seal 17 and carrying a detonator 18. Centrifugal locking means 24 and 25 or a set-back lock-pin (not shown) secures the piston in its safe position. On firing a projectile fitted with the mechanism, the locking means are released and centrifugal force pushes the liquid through an orifice 19 and to the rear face of the piston, whereby the piston slowly moves towards the spin axis. This movement is accelerated when the seal 17 reaches grooves 40 and 41 and permits more rapid fluid flow to the rear face of the piston. In the armed position the detonator 18 is aligned with a firing pin. The fluid in the cavity may be silicone.

The container comes into juxtaposition with a further work holder 12 which carries the container 2' having a plastics coating to the entrance of equipment 11 where the coating is cured. Work holders 5 after releasing containers 2 may be cleaned by spraying with, air or other gas or a suitable solvent, at 30.
