Title: Improvements in or relating to safety devices for fire arms
IPC: F41A17/64
Filed: 1935-08-20
Abstract: 453,672. Safety device for firearms. MAUSER-WERKE AKT.-GES., Oberndorfon-Neckar, Germany. Aug. 20, 1935, No. 23407. Convention date, Aug. 20, 1934. [Class 119] The firing-pin 3 of a firearm is adapted to be displaced transversely or at an angle to its axis to put it out of reach of the cock 5 In the pistol shown, a shoulder 6 on the firing-pin engages a notch 7, when the firing-pin is deflected, and positively prevents operation of firing-pin. The rear end of the firing-pin passes between shoulders 1, 2 in a transverse bolt 4, the rotational position of which determines the position of the firing-pin. A safety catch 9 for the cock 5 has arms 8, 10 and 13 co-operating with the transverse bolt 4. When this bolt is in the safe position shown, the arm 8 is depressed and a lug 9<a> on the safety catch prevents the cocking of the cock. The pistol may however be loaded by the retraction of the breech-block. During the opening movement, the arm 8 is released and the cock cocked ; and on the return of the breech-block, the arm 10 is deflected by the transverse bolt and releases the cock, but the arm 8 is immediately afterwards again depressed and the cock locked by the lug 9<a>. When the transverse bolt is set to the firing- position, slots in this bolt come in the path of the arms 8, 10 which are thus made free ; but a return of the transverse bolt to the safe position deflects the arm 13 and again causes the return of the safety catch 9 and cock 5 to the safe position. The Specification as open to inspection under Sect. 91 also comprised the subject-matter of Specification 451,466. This subject-matter does not appear in the Specification as accepted.

Abstract: 1388379 Reducing drag on aircraft HAWKER SIDDELEY AVIATION Ltd 10 June 1969 [21 May 1963] 24246/68 Heading F2R An aircraft fuselage, or like aerodynamic body, for supersonic flight but having a comparitively short rear end fairing suitable merely for subsonic flight has the excessive drag penalty that would otherwise occur in supersonic flight overcome by burning fuel at the exterior of the fuselage in the region of the forward end of the tail fairing. In the preferred form, the external burning starts just ahead of the region where expansion shock and breakaway of the boundary layer would take place during supersonic flight in the absence of such burning. By this means it is possible to provide the necessary space for the installation of direct lift engines in an aircraft capable of supersonic flight over a reasonable range. Quite simple burners can be employed situated at intervals in a line around the fuselage with the appropriate fuel supply lines and fuel rate control valves within the fuselage.
