Title: Improvements in or relating to pyrophoric liquefied gas lighters
IPC: F23Q2/167
Filed: 1953-02-18
Abstract: 727,195. Lighters utilizing liquefied gas fuel. NATIONALE SOC. ANON. Feb. 18, 1953 [April 1, 1952], No. 4521/53. Class 75 (3). In a pyrophoric liquefied gas lighter having a portion of the fuel supply. tube of variable reduced cross-sectional area to control the flow of gas to the burner, a thermal resistance is located between the said portion and the burner and is so constituted that the heat transmitted to the said portion is at most equal to the heat of vaporization of the gas consumed. As shown this thermal resistance is constituted by the annular gas filled space 19 between an extension sleeve 15 of the fuel supply pipe 4 and the nozzle burner tube 16 which is slidably held in the sleeve by the turnedin end of the latter. The supply nozzle 14 on the end of the pipe 4 within the sleeve 15 is closed by a rubber member 20 on depression of the tube 16 by contact with the stop 25 on closure of the cover 24. The supply pipe 4 has a portion 13 of reduced cross-sectional area produced by flattening and then bending the tube and is adjustable by varying the free burner end position of the pipe by a screw actuated sleeve 21 against which the pipe is pressed by a spring 23. The nozzle tube 16 has a radial opening 18 communicating with the said annular space 19. The lower part of the pipe 4 is located in a fixing tube 5 with an enlargement 6 and internal recess larger than the external diameter of the pipe 4. The recess is connected with the storage chamber 2 by a passage 7. The pipe 4 is secured in the tube 5 by two rubber washers 8.compressed by a tightening screw 12 to form a fluid-tight joint and to clamp pipe 4 and between which washers is located a metal ring 9 loosely fitting over the pipe 4 and with a groove on its outer surface, and radial perforations 10. In another embodiment the thermal resistance is formed bv a small diameter tube with sufficiently thin walls welded in the end of tube 4 and forming the burner. The stop 25 on the cover is then of rubber, for example, to close the end of the burner tube on closure of the cover. Reference has been directed by the Comptroller to Specification 673,822.

IPC: B01D37/02
Filed: 1954-02-16
Abstract: 755,243. Filters. INFILCO, Inc. Feb. 16, 1954 [Feb. 16, 1953], No. 4539/54. Class 46. Liquid to be filtered is introduced at 21, Fig. 1, through a valve 19 and filters through filter aid material deposited on the pervious lower portion 34 of each of a number of filter units 30<SP>1</SP>, 302. Air is trapped in the top portion 12 of a casing 10 by introduction of the liquid, and the passage of filtrate into the units 301, 30<SP>2</SP>. causes air to be trapped in an impervious, upper portion 33 of each unit. Filtrate from the outer units 30<SP>2</SP> passes by pipes 45 into a central unit 301, the lower end of which has an outlet port 37 and fits in a socket 35 on an outlet pipe 25. When backwashing of the units is necessary an air release valve 28 (preferably quickacting) is opened, the "release air " hitherto trapped under the top portion 12 thereby escaping, and the " operating air " trapped in the upper impervious portion of each filter unit thereupon expanding and driving filtrate back through the pervious portion at high velocity. The filter cake is thereby broken off and the unit.interstices cleaned. Compressed air is then admitted at 29 to maintain the solids in suspension during discharge of the dirty liquid through a drain valve 23. In Fig. 3 (not shown), the pervious and impervious parts of each filter unit are made separately but clamped together in use. Withdrawal of filtrate may be by means of an upper header 56, Fig. 4, which also supports the weight of the units and communicates with each by a conduit 55 extending through the " operating air " space. In this arrangement the filtrate may be withdrawn from the outer units downwards through the central unit instead of from all units through the conduit 25b as shown. Each unit may in every case comprise two or more sections 60, 61, Fig. 5, each section comprising an upper impervious portion 33c and a lower pervious portion 34c, each section except the uppermost communicating with the one above it for discharge of filtrate by a pipe 62, and the filtrate from the compound unit being withdrawn at 45c. In Fig. 8, each unit may comprise a cylindrical element 30f, Fig. 11, including an open-bottomed "release air" trap 762 extending substantially the length of the unit. This trap may be omitted, in which case the impervious portion 33e of the cylindrical wall extends nearly half-way down on each side of the vertical. Specification 524,385 is referred to.

Title: Method for nitriding steel
Inventor: STAUFFER FRIEDRICH
IPC: C23C8/26
Filed: 1954-02-22
Abstract: A method for nitriding steel, in which in a part of the treating period the steel is exposed to the temperature necessary for nitriding, while in the other part of the treating period the steel is exposed to a higher temperature for preventing embrittlement of the core material, is characterized in that after the said treating period the temperature is at first lowered quickly to below the nitriding temperature and then lowered comparatively slowly, this temperature-lowering taking place in a gas atmosphere.  The steel may be exposed to the higher temperature before or after exposure to the lower nitriding temperature and this higher temperature is preferably chosen to be close below the re-annealing or tempering temperature of a preceding heat treatment.  The temperature-lowering make take place in the nitriding atmosphere or may be carried out partially or wholly in another gas, such as air.  One example relates to the nitriding of firearm barrels made of steel containing 0.3 per cent C., 1.5 per cent Cr, 1.5 per cent Al, 1.2 per cent Ni and 0.3 per cent Mo in which the work-pieces are first nitrided in ammonia gas at 450 DEG to 500 DEG C. for 50 hours, heated to 600 DEG  to 650 DEG C. for 10 hours, cooled for 5 hours to 200 DEG  to 300 DEG C. and then cooled more slowly for 19 hours to 70C'., the cooling taking place in the nitriding gas.  The other three examples similarly relate to the nitriding in ammonia gas of steels containing (a) 0.3 per cent C, 3 per cent Cr, 1.5 per cent Al, 1.2 per cent Ni and 0.3 per cent Mo, (b) 0.15 per cent C, 1 per cent Cr and 1 per cent Mo, (c) 0.15 per cent C, 3 per cent C and 1 per cent Mo and (d) 0.3 per cent C, 1 per cent Cr, 1 per cent Ni, 0.3 per cent Mo and 1 per cent Al.
