Title: Improvements in apparatus for igniting cartridges for generating motive fluid for driving machinery
IPC: F02B45/02
Filed: 1938-06-15
Abstract: 515,951. Generating combustion products under pressure ; gun breech mechanism ; gun cartridges. CLEVELAND, F. J. (Eclipse Aviation Corporation). June 15, 1938, No. 17830. [A Specification was laid open to inspection under Sect. 91 of the Acts, Dec. 19, 1938.] [Class 51 (i)] [Also in Group XXI] Relates to apparatus for generating gases under pressure for power purposes of the kind in which the gases are generated by the ignition of a cartridge 11 in a chamber 71. According to the invention, a device is provided which simultaneously locks the breech mechanism and moves the firing pin to ignite the cartridge. In the construction shown, the breech mechanism comprises a cover plate made in two sections 27, 28, which are secured together at 29. The section 27 houses a spring 23 which bears on the head of the firing pin 21 and urges the latter towards the cartridge. The ignition of the cartridge is effected by an electric current which passes through the spring 23 and firing pin. The latter is mounted in a sleeve 24 of non-conducting material and the sliding movements of the sleeve are controlled by a screw 32 which is slidably mounted on pins 34. The screw is mounted in a nut. 31 geared to a handle 41, whereby, on rotating the handle, the screw 32 and the spring-urged sleeve and'firing pin receive a sliding movement. The handle is mounted in a shaft 52 which carries a detent 53 adapted to engage behind a lug 61 of the breech-casing 62 and thereby to effect the locking of the breech mechanism. The locking movement occurs simultaneously with the movement of the pin 21 towards its firing position. A recess 83 in the detent is adapted, when the detent is in the locked position, to receive one end of a rod 82 the other end of which co-acts with a ball-valve 77. In this position of the rod, the valve closes a passage 73 leading to the atmosphere. When the detent is moved to the unlocked position, the rod 82 is moved to lift the valve from its seating and the gases in the chamber 71 are exhausted via passages 72, 73. As shown in Fig. 6, the opening of the breech cover plate about its pivot 96 is prevented until the chamber 71 is exhausted by means of a piston 103 the rod 101 engages beneath a nose 97 of the cover plate so long as any gases remain in the chamber. This nose also co-acts with a cartridge-ejecting device 98. The cartridge contains a slow-burning charge 11 which is separated from the primer charge 13 by a cup-shaped partition 14 of inflammable material. In order to convey the electric current from the firing pin to the charge 13, a strip 16 bent to the shape shown is provided, one edge of the strip extending along the outer metallic cap 17 which fits over the end of the cartridge.

Title: Improvements in method and apparatus for the purification of crystals
IPC: C07C201/16
Filed: 1955-06-21
Abstract: <PICT:0771038/III/1> A process for the purification of cystals such as for the separation and purification of at least one of the components of a mixture having at least one but not all of its components in crystalline form, comprises heating the crystals, introducing the heated crystals into an upstream portion (with respect to crystal movement) of an elongated purification zone, moving the crystals as a compact mass toward one end of the zone, melting at least a portion of the compact mass in the downstream end portion of the zone, displacing a portion of the resulting melt countercurrently through at least a portion of the length of the crystal mass to displace occluded impurities therefrom, removing displaced liquid from an upstream end portion (with respect to crystal movement) of the zone, and removing a purified product from the downstream end portion of the zone.  A mixture of materials is fed by a conduit 11 (Fig. 1) to a heat exchanger such as a chiller 12 to obtain crystals of at least a portion of at least one constituent of the mixture.  The slurry so obtained is fed to a filter 14 where uncrystallized material is removed.  Crystals are then passed by a conduit 16 to a heating chamber 17 to melt a portion of the crystals to obtain a slurry, preferably containing 35 to 45 per cent by weight of solids, which is passed by a conduit 22 to a column 23.  A piston 25 compacts the crystal mass and moves it downstream towards a heating element 28.  A filter 29 removes liquid from the crystal mass, or the piston 25 may have a perforate lower face through which liquid may be removed.  A portion of the material melted by heater 28 is displaced upstream through the compact crystal mass, thereby displacing occluded impurities from the crystals, the liquid being removed by filter 29, or through piston 25 when it is perforate. Purified material, which may be molten or partially solid, is removed through a conduit 32.  In modifications conduits 16 and 22 may be heated and conduit 22 may be inclined.  In a further modification material from heater 17 is passed through a chiller to cause further crystalliation before entering column 23.  In examples para-xylene is separated from a mixture also containing ortho- and meta-xylenes, ethyl benzene and toluene.  Lists are given of compounds which may be separated by the process.
