Title: Improvements in process for chromizing and product
IPC: C23C10/12
Filed: 1962-05-24
Abstract: In a process of chromizing ferrous material in a closed retort at 1500 - 2300  DEG F. a gas containing at least 2% by volume of a halogen, preferably in a hydrogen carrier, is continuously circulated through a source of chromium and the ferrous material, which is out of contact with the chromium source.  The chromizing gas <PICT:0975202/C6-C7/1> is preferably hydrogen bromide, chromous bromide or bromine or a mixture of halides and the chromium source may be chromium or ferrochromium in the form of minus 1/4 inch plus 60 mesh pieces.  The dew point of the exit gases from the retort should not be more than +5  DEG F. and preferably should be lower than -40  DEG F.  The ferrous material treated should have a maximum carbon content of 0.03% and may be silicon steel, chromium and nickel stainless steel or steels stabilized with titanium, niobium, vanadium or tantalum.  Prior to chromizing the steel may be decarburized in the retort by treating at 1300 - 1400  DEG F. with wet hydrogen.  In one embodiment, Fig. 1, of a batch process, open coil steel strip 38 is supported by a grid 35 of plenum chamber 31 in a bell type furnace retort 54.  The chromium source is supported in stacked trays 40 and the halogen gas is supplied via inlet 61 and circulated by fan 25 through the chromium and the coil, a series of baffles directing the gas through the coil in the direction of the arrows.  The source of chromium may alternatively be in the form of a porous bell, Fig. 8 (not shown), or as a filling in the hollow core of the ferrous coil, Fig. 9 (not shown).  In a continuous process shown in Fig. 4 steel strip or wire is continuously passed through perforated tubes 75 enclosed in a sealed retort 74 the space between the tubes being packed with the source of chromium 85.  The circulating gas is supplied via inlet 96 and the treated wires are removed from plugs 92.  In another embodiment, Fig. 6 <PICT:0975202/C6-C7/2> (not shown), a shaker hearth extends into the retort and conveys the workpieces into the retort for continuous treatment with the chromizing atmosphere and the treated pieces are then quenched directly in a quenching tank.  In the batch type process the chromized work may be given a heat treatment in the same retort, the halogen gas being first purged and the heat treatment effected in hydrogen or other carrier gas.  In the continuous process the heat treatment is effected in a separate furnace free of halogen gas or a non-chromizing flushing gas may be introduced into the discharge end of the continuous retort.

Title: Improved means for maintaining constant differential pressure on valves, particularly for use in the gravity dosing of chemical solutions
IPC: F16K31/18
Filed: 1943-12-07
Abstract: 574,952. Regulating pressure of fluids on valves. MOORE, R. P. Dec. 7, 1943, No. 20468. [Class 135] To maintain a constant differential pressure between the inlet and outlet of a valve fed from a tank, the valve is located outside the tank and-below the lowest level assumed by the liquid therein, and the liquid passing through the valve is led over a weir situated in a float in the tank. Liquid in the tank can pass through a strainer 10 in the bottom of the float 1, Figs. 1 and 2, and along a passage 14 and a flexible tube 16 to the valve 20. From the valve, the liquid is led through another flexible tube 32 to a passage 34 in the float, over a knife-edge weir 36, and out through a passage 37, flexible tube 41, and a drip funnel and tube 45 to a weir chamber 46. The weir 36 is situated at the centre of gravity of the float and may be adjustable in height. Vents 60, 61 prevent syphonic action in the system. The valve consists of a hard rubber body with inlet and outlet passages 19, 29, Fig. 5, respectively, and an orifice defined by a knife-edge 23 and a mercury or other liquid surface 26. The knife-edge is arched upwardly and the level of the mercury can be adjusted by a screw plunger 27 to vary the area of the orifice. If the knifeedge is situated off-centre, the orifice can also be regulated automatically in accordance with the height of the liquid in chamber 46 by means of a float 57, Fig. 1. The latter is connected to a lever 52, the other end carrying an adjustable tappet 50 supporting a weighted arm 48 attached to the valve which, in this case, is pivoted at 47. Movement of the float 57 tilts the valve and allows the mercury to flow to the side and thus alter the area of the orifice. Specification 565,726 is referred to.
