Title: A process for the production of solid spheres and a furnace for carrying out the said process
IPC: C01B31/30
Filed: 1964-10-06
Abstract: <PICT:1080775/C6-C7/1> Spheres of 100-1000 micron diameter of material having a high melting point e.g. uranium, uranium carbide and oxide are formed by melting the material in ingot or powder form in an argon plasma furnace and subjecting the liquid as it forms to centrifugal force whereby droplets are ejected into a controlled inert atmosphere in which the solidify. As shown the plasma furnace comprises a cylindrical working chamber 1 having double, liquid cooled walls 1a, 1b and slightly curved ends 5, 6 through which extend axially a plasma burner 2 (see Division H5) and a rotatable spindle 3 supporting a container 26 in which the material is carried. The chamber has observation windows 74, an air lock for extracting samples and may have an orifice for passing through a handling gripper. The burner comprising a conical, tungsten cathode and an anode, both water cooled, is supplied with argon which ionizes to form plasma which is ejected through orifice 8 to form a flame 40-150mm long which impinges on the material in the container, its base 26 being of copper. The spindle, comprising five concentric tubes forming two separate water cooled circuits, is rotatably mounted on a slide 18 permitting axial movement, in addition the inner tubes slide axially to maintain constant the distance between the burner and the face of the material in the container. The chamber is first evacuated by a vacuum pump 17, then during operation, with the spindle rotating at 2000 r.p.m. the atmosphere is maintained oxygen free and slightly above atmospheric pressure by the incoming Argon which exhausts through a pipe 12 containing a heat exchanger 14. In a modification the material in powder form entrained in argon is introduced into the plasma by injecting it into the burner upstream of the orifice 8. The material then impinges on to the bottom 26 of the container which rotates and ejects droplets. The furnace may be arranged vertically with the burner at the top.ALSO:Spheres of 100-1000 micron diameter of uranium carbide are formed (see Div. B5) in an argon plasma furnace (see Div. F4) by heating a mixture of uranium oxide and carbon, melting the resultant carbide and subjecting the liquid to centrifugal force whereby droplets are ejected into an inert oxygen free atmosphere in which they solidify.

Title: Annealing lehr for glass sheets with reradiating side wall plates
IPC: C03B25/08
Filed: 1965-06-19
Abstract: A method of annealing a glass sheet supported upon its bottom marginal edge portions during its movement through an enclosed atmosphere through its annealing range wherein the remainder of the bottom surface, not in contact with the support, is directly exposed to the atmosphere and the exposed portion of the bottom surface of the glass sheet is cooler than the upper surface of said glass sheet as the glass sheet cools through the annealing range, comprises selectively imparting heat to a lower portion of the enclosed atmosphere facing the bottom surface of the sheet during its movement through the annealing range both to reduce the difference in cooling rate between the bottom marginal edge portions in contact with the support and the remaining exposed bottom surface, and to reduce the natural vertical temperature gradient from the bottom surface of the glass sheet to the top surface thereof. In a preferred embodiment a glass sheet is supported at its marginal edges by a skeleton-type bending mould 34 which is conveyed through heating, bending and annealing zones on stub rollers 12 (Fig. 2, not shown). Radiant heaters in the furnace roof bring the sheet to near its softening temperature. It is the conveyed through the bending zone where, having been brought to its softening temperature by roof radiant heaters 46 (Fig. 1, not shown) and "crease" heaters 48, it sags into and takes the shape of the supporting mould 34. The bent sheet supported upon its mould is then conveyed into and through the annealing lehr. In the zone the temperature of which decreases from just above to just below the annealing range 1/4 -inch cold rolled steel plates 56 (Figs. 2 and 3, not shown) are placed along the length of lehr floor and extend across the width of the floor. Similar plates 58 are fitted inwardly of the side walls of the lehr above the stub rollers 12 but below the top of the curved-up ends of the bent sheet. These plates 56, 58 serve to absorb and re-radiate some of the heat and thereby reduce the temperature gradients which may occur along the bottom surface of and through the glass sheet. In an alternative embodiment (Fig. 4, not shown) the steel plates 56, 58 may be dispensed with and horizontally movable gas burners inserted along the length of the lehr-side wall through the annealing range at such a height that the flames are directed towards the bottom surface of the glass sheet. If desired, only the side-wall plates 58 need be removed.

Title: Volume controlling means for hydraulic brakes
IPC: F16D65/22
Filed: 1966-03-03
Abstract: An hydraulic braking system for an automobile in which each of the two brakes 32, 321 of one axle has a double fluid-supply circuit and comprises a wheel cylinder 31 having a primary chamber 31, a primary piston 36, a secondary chamber 38 and a secondary piston 40, the pistons being associated with braking members 41, a master cylinder 10 supplying the said primary chambers, the secondary chambers being connected to a secondary circuit 58 which communicates on the one hand with a transfer chamber 21 of the master cylinder and on the other with the wheel cylinders 44, 441 of two brakes on a second axle, has means for reducing the demand for fluid when the brakes are applied during reverse running of the vehicle. When the brake pedal 15 is actuated during forward movement (arrow F) fluid is supplied to primary chamber 31 to actuate piston 36, the frictional drag on the shoes moving piste n 40 to decrease the volume of chamber 38, the increased pressure therein being transmitted by lines 58, 59 to the rear brake wheel cylinders 44, 441. In one embodiment (Fig. 2), of the wheel cylinders 32, 321, the secondary piston 40 has abutment means comprising a nut 54 on a tail of the piston which prevents the latter moving rightwards, thus preventing the volume of chamber 38, and hence the demand for fluid, increasing when the brakes are applied during reverse movement of the vehicle. In two other embodiments (Figs. 4 and 5, not shown), abutments between the outer end of the piston 40 and its cylinder serve the same purpose. In the second of these other embodiments the pressure in chamber 38 is also arranged to act on a tail of the primary piston. In the embodiment of Fig. 6, the piston 40 is free to move in the reverse running direction, a separation ring 83 with a fluid-tight joint 87 is provided to limit the volume of chamber 38 during braking in the course of reverse running. In a final embodiment, Figs. 7 and 8, the transfer chamber 21 is connected to an extension chamber 88 connected by conduit 92 to the secondary chambers 38 and 381 by a passage controlled by a valve 93 tiltable by a collar 94 on a plunger 89. The latter is subjected on one side to the pressure in chamber 88 and on the other to that in the master cylinder chamber 20. A further plunger 90 is subjected to the pressures in chamber 88 and master cylinder chamber 22. At rest and during braking in the forward running direction the plunger 89 is in a position where the valve 93 is open. During braking in the reverse running direction the pressure in chamber 88 is lower than that in chamber 20 and the plunger moves rightwards to permit valve 93 to close and cut off fluid communication with secondary chambers 38, 381. A pressure intensifier 60 is provided which allows communication between chamber 21 and lines 58, 59 until the pressure in line 57 reaches a predetermined value, when a valve in the intensifier closes to cut off line 57 from line 58 and establish an intensifier action.

IPC: B01D1/00
Filed: 1969-02-22
Abstract: A process for preparing a reverse osmosis membrane comprises preparing a dope containing a solvent, casting a film from the dope on a support, forming a skin on the film's free surface by allowing part of the solvent to evaporate from the free surface, and immersing the film on its support in a liquid so that the liquid advances over the free surface at a rate lying in the range of from 40 mm./sec. to 500 mm./sec. The process may further include heating the film while it is immersed in a liquid. The liquid's advance rate preferably lies within the range of from 50 mm./sec. to 100 mm./sec., and may throughout the immersion period vary by at most 10%, and preferably 3%, from the mean value. The advance rate may be substantially constant. The film may be cast on a support plate 1 which may be inclined to the horizontal and which may be immersed by fluidoperated jack 5 in liquid 4 to cause the liquid to flow over the free, inclined, film surface. The production of a membrane from a dope containing cellulose acetate, acetone, water, zinc chloride and hydrochloric acid is exemplified, the membrane being cast on a support plate inclined at 1 48' 12' to the horizontal, immersed in water, and subsequently heated in water.
