Title: Alpha-methylstyrene derivatives and method of making same
IPC: C07C25/24
Filed: 1948-11-18
Abstract: 3 - Chloro - 4 - methylisopropenylbenzene is prepared by passing chlorine into contact with p-cymene in the presence of a nuclear chlorination catalyst and in the substantial absence of light to give 3-chloro-4-methylisopropylbenzene, and then dehydrogenating this. The dehydrogenation step is preferably carried out at 550-700 DEG  C. in the presence of an excess of a gaseous diluent, e.g. steam or o-chlorotoluene, which may be superheated.  The product is separated and purified by fractional distillation.  In an example, p-cymene is chlorinated in the presence of iron filings and the product dehydrogenated. Specification 687,265, [Group IV (a)], is referred to.  The Specification as open to inspection under Sect. 91 comprises the statement that alkylation of toluene with, for example, propene or isopropyl chloride or alcohol affords meta- or paracymene or mixtures of the two depending on the conditions. The m-cymene and mixtures of m- and p-cymene may be chlorinated and dehydrogenated to give 3-methyl-4-chloroisopropenylbenzene and mixtures of this with the 3-chloro-4-methyl isomer respectively.  Two examples are given of this aspect of the invention.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in and relating to the projection of projectiles
Inventor: TUMBER CLIFFORD FREDERIC
IPC: F41B11/57
Filed: 1949-11-28
Abstract: 679,269. Ordnance; projectiles. MINISTER OF SUPPLY. Nov. 28, 1950. [Nov. 28, 1949] No. 30398/49. Classes 9 (i) and 92 (ii). Projectiles are fired at high velocity by apparatus comprising a chamber of unvarying capacity, the chamber being sealed from the barrel bore by the projectile which is temporarily restrained from passage along the bore, and means being provided for supplying the chamber with a precompressed gas and for increasing the pressure of the gas when in the chamber by heating alone, or by heating and the development of additional gas. In the construction shown in Fig. 2 the barrel 9 screwed into a member 8 which screws into a main steel body 1. A second member 4 screwed into the body 1 is spaced from the member 8 to form a cylindrical chamber 3 which houses a cordite charge 5 and a resistance wire 6. Between the barrel and the chamber there are arranged a frangible support 12 for the projectile 11, copper packing 13, and a high tensile steel insert 14. In operation a gas, such as hydrogen, under pressure is introduced into the chamber 3 through a valve 18 in the member 4, and the charge 5 is then fired by a current passing through a lead 7 and the resistance 6. The consequential high increase in pressure causes the projectile 11 to overcome the resistance of the thin supporting section 12a of the support 12 and to pass down the barrel. The expansion of the gas may alternatively be effected by heating alone. In a modification, Fig. 3, the rear end of the projectile is formed with a flange 19 which ruptures at 19a when high pressure exists in the chamber 3, thus enabling the projectile proper to be fired through the barrel.
