The cock is especially applicable to the fuel systems of aircraft and may be fitted in a cavity in the fuel tank to minimize the risk of damage thereto when a crash occurs. The main plug 8 is pressed to its seating 9 in the cock casing 2, by a spring 10 retained by a flanged ring 11. The casing 2 has threaded pipe connections 3, 4 and a reduced part 5 internally threaded to receive a packing gland 6. The base of the casing is closed by a screwed cover member 12 which receives a cap-shaped device 15 containing the fuse 16. The auxiliary plug 14 is screwed on to the exterior of the device 15, the threads being automatically stripped when the explosive charge which is placed above the fuse 16 and the device 15 is detonated. The plug 14 and the recess 18 are tapered at an angle less than the friction angle between the material of the two parts so that the plug is self-jamming. The electric leads 17 to the fuse 16 pass through the member 15 to terminals 22 in an insulating base 19 secured to the cover 12 by studs. Nuts 25 on these studs secure a cover 24 to the base 19. The fuse 16 may be energized by an inertia operated switch or by a switch operated by the pilot. The stem 7 of the. main plug 8 is fitted with an operating handle 26 and is made hollow to facilitate release of the auxiliary plug 14 from the recess 18. The Provisional Specification describes a form in which the plug cock is dispensed with and also a form having a plug with a screwed stem which is weakened at one point for fracture by an explosive charge. Forms are also described in which the explosive charge closes the valve by fracturing a flange on a hollow plug or by shearing a pin on the valve stem. Sleeved wires or other remote control means for re-setting the cocks are also referred to. Inertia operated valves are also referred to. A fuel feed system having non- return valves in the supply and return lines between a fuel tank and a force pump is described.

Patent GB-600303-A (GB)
Title: Alloy
IPC: C22C9/01
Filed: 1943-07-05
Abstract: A fine grain beryllium-copper base alloy capable of being cast and of being work-hardened on the surface in use and having a tensile strength comparable to that of steel, consists of: Cu 60-93 per cent, Be .10-11 per cent, Ni .55-7 per cent, Al 1-20 per cent, As .10-2 per cent.  The alloy may contain Hg not exceeding .15 per cent and the As may be omitted when Hg is present.  In making the alloy, pure copper is placed in the bottom of the melting pot, arsenic, if to be present, is placed on the copper, then copper-nickel shot, then more copper.  Graphite is generally added, and heat is applied, slowly at first, to melt the mixture. Preheated beryllium-copper concentrate is then slowly added, the mixture being agitated when molten.  The temperature is then allowed to drop to about 50 degrees C. over the freezing point of the melt.  If no mercury is to be included, the aluminium is then added.  If mercury is to be included, it is added in the form of an aluminium-mercury alloy formed by placing aluminium foil in contact with mercury for at least 24 hours.  Before the aluminium-mercury alloy is melted, the temperature is preferably increased and held for a period to allow the mercury to act as a deoxidant, and to allow the escape of gases from the melt.

Abstract: 108,521. Jerram, A. E., Ricks, F., and British United Shoe Machinery Co. Aug 8, 1916. Slugging.-Fastener-inserting or other machines for operating upon boots or shoes or parts thereof having mechanism adapted to perform the same operation repeatedly on a work piece fed through the machine and provided with means controlled by a change in contour of the work to effect automatic interruption of the action of this mechanism upon the work at a pre-determined distance from such change, such as described in Specifications 28,927/09, 12,539/10, and 16,481/15, are provided with further means adapted to render the first means insensitive to any change in contour other than the predetermined controlling change. The invention is described with reference to the device described in Specification 12,539/10. The work-engaging member 450 has the forward portion of that part of it forward of its horizontal pivot 452 cut away and replaced by a short arm 479, which is mounted to swing through a limited amount on a vertical pivot 480. The arm is provided with a lug 450* to engage the top surface of the work a, and with a vertical lug 486 or pin &c. which engages the edge of the work, and is urged normally to its forward position by a spring 481. This construction prevents the lug 450* from passing off the face of the work except when the end of the work piece is reached, even should the operator fail to swing the work sufficiently towards the machine as slugging proceeds round a sharp curve. In a second construction, the work-engaging member 450 is prevented from downward movement by a locking member in connexion with the starting treadle, the member remaining operative so long as the operator keeps the treadle depressed. When, however, the operator releases the treadle, the locking-member releases the member 450 which then operates automatically to stop slugging as described in Specification 12,539/10.
