Abstract: 1,122,270. Machinery guards. PACKAGE MACHINERY CO. 3 March, 1967 [31 May, 1966], No. 10094/67. Heading F2J. In a plastic injection moulding machine comprising a movable stock 14 carrying one die and a rigidly mounted support plate 24 carrying another die, operator access between the dies is prevented by a gate 38 which operates cam mechanism which allows movement of the movable die towards the fixed die only when the gate 38 is in the closed position. The gate 38 is slidably mounted on fixed rails 34, 36 by means of rollers 44, one of which is mounted on a bracket 46 carrying a cam 58. A pivotally mounted follower 60 carries a plunger 64 which is adapted to engage a block 66 threaded on to one end of a shaft 70, the other end of which carries a cam 74 which is adapted to co-operate with a roller 76 on a latch member 78. A guide rod 30 attached to the movable die has a series of teeth 82 which are adapted to be engaged by latch member 78 to prevent movement of the movable die towards the fixed die when the gate 38 is open. When the gate 38 is moved to its closed position, an arm 84, secured to bracket 44, engages block 66, thereby moving shaft 70 to the right, as seen in Fig. 1, and causing cam 74 to engage roller 76 and lift latch 78 clear of teeth 82. When the initial position of the movable stock 14 is adjusted, by rotation of nuts 18 or threaded beams 16, the shaft 70 is also moved axially by rotation of a chainwheel 86 mounted thereon. An additional safety device comprises a limit switch 48 in the control circuit of a motor driving a pump providing hydraulic pressure for die movement. A further safety device comprises a valve 52 controlling the flow of fluid for die operation, the valve being opened by the engagement of a cam 56 on the gate 38 with a member 54 on the valve 52.

Title: Purification of titanium tetrachloride
IPC: C01G23/02
Filed: 1958-04-01
Abstract: <PICT:0874551/III/1> Titanium tetrachloride is purified by introducing a stream of superheated titanium tetrachloride into a pool of liquid titanium tetrachloride containing a carbonisable organic reducing agent at a point below the surface thereof to agitate and heat said pool and to distil purified titanium tetrachloride therefrom, said stream of liquid titanium tetrachloride prior to its release into said pool being at a temperature above the boiling point of titanium tetrachloride at the pressure imposed on said stream after its release into said pool.  In an example using the illustrated flow diagram, titanium tetrachloride containing 0.25% by weight of vanadium, measured as V2O5, is supplied from a tank 1 to treatment tank 2, preferably made of iron or steel and insulated with cellular glass, and continuously removed therefrom by line 6 by means of pump 4 through indirect heat exchanger 5 and back to the treatment tank through a pipe 3 having a bend 15 and constricted end 18.  Pipe 3 can be replaced by multiple pipes or a pipe having multiple openings.  In the heat exchanger the titanium tetrachloride is superheated by reason of the back pressure due to the constriction. When the whole of the pool reaches the desired temperature as indicated by the appearance of distillate in the reflux tank 13 (v.i.), a high grade lubricating oil is introduced from tank 7 into the treatment tank.  Reducing agents mentioned are other animal, vegetable or mineral oils and soap.  In general 0.5, preferably 0.75, lbs. of reducing agent per lb. of vanadium present, is added.  The distillate passes through a still 9 of the plate or packed column type and thence to a condenser 10.  A further condenser 11 recovers uncondensed material before venting the gases to the atmosphere or elsewhere, and returns said material to condenser 10.  Condensed titanium tetrachloride is passed to reflux tank 13 and is partly recycled to the still and partly removed as product.  When two-thirds of the impure titanium tetrachloride has distilled off, a portion of the remaining amount (containing thixotropic material) is removed into collecting tank 17 and the treatment tank is refilled from tank 1 for a repetition of the treatment.  Other impurities referred to are iron, zirconium, calcium and chromium.

Title: Improvements in and connected with apparatus for feeding water to boilers under pressure
IPC: F22D5/04
Filed: 1921-04-09
Abstract: 181,179. Siciliano, A. April 9, 1921. Feed-water, supplying and controlling.-In feedwater-regulators of the type in which the feed inlet valve is controlled by the movement of a hollow vessel or receptacle such as D in communication with the interior of the boiler O and mounted on a counter-weighted lever as B1, communication between the hollow vessel and the interior of the boiler is established at the normal water level through a tubular pivotal connection A, Fig. 2, on the boiler front and about which the lever is pivoted. The movement of the receptacle due to its change in weight. according as it is filled with water or steam, is utilized to operate directly on the feed-inlet valve or to open or close a reservoir H, through a valve X, to the pressure of steam in the boiler so that on opening, water flows into the boiler past the check valve K2, the reservoir H being maintained full from a main, back flow being prevented by a check valve K. As the water-level falls below normal, steam fills the receptacle D via the connection A and hollow arm B of the lever and the adjustable counterweight C drops, pushing up the rod V and opening the feed check valve. Feed-water then enters the boiler until the tubular connection A is sealed, whereupon the steam in the receptacle D condenses and the feed check valve is closed, the length of the rod V being so adjusted that the receptacle D when full of water is in its horizontal position. Equilibrium of boiler pressure is established on the water in the receptacle by means of a connection U, which may be flexible, from an opening M in the steamtight sleeve B on the tubular pivot A to the highest point of the receptacle D, so that as the water-level again falls, water flows out from the receptacle D back into the boiler and the cycles of operations is repeated.
