Abstract: 1336778 Fluid-pressure control of liquid level BENDIX CORP 30 Sept 1971 [30 Sept 1970] 45650/71 Heading G3P A valve 34 in a passage 30 through which liquid, such as fuel, is supplied to a container 12 is closed when a level sensor 166 restricts the flow of liquid through a passage 128 to cause the jet from a monostable amplifier 26 to be switched from an outlet 256 to an outlet 254. The supply port 246 to the amplifier is fed from the inlet to the valve 30 by a pair of conduits 258, 262 and a valve 24 having a diaphragm actuator 228 in the form of a Belleville washer. The conduit 262 also feeds the passage 128 through a restriction 268. With the valve 34 open, the pressure from the outlet 256 is applied to a space 56 at the right hand side of a diaphragm actuator for the valve 34 while the space 56 at the left hand side is connected to a vent line 126 through conduits 278, 284. When the liquid reaches the required level increased pressure at port 249 due to restricted flow in the passage 128 switches the jet to outlet 254 reversing the pressure differential across the actuator for the valve 34 to close it. Pressure from the outlet 254 is also applied to opposite sides of the Belleville washer 228 through conduits 276 and 282 which are separated by a restriction so that the valve 24 closes. This valve is opened manually when a further container is to be filled and a further manually operated valve 22 enables the valve 34 to be opened when the fluid supply pressure is insufficient to create a high enough pressure differential to operate the device. The system is constructed as a compact unit with a known latching mechanism to connect it with the container to be filled, the air vent from the container extending through the centre of the main valve spindle and being surrounded by an annular space forming the sensing passage.

Abstract: 1,269,450. Solution mining. OCCIDENTAL PETROLEUM CORP. 25 Sept., 1970 [2 Oct., 1969], No. 45691/70. Heading E1F. A solution mine is formed by sinking a well 10 into a soluble formation, injecting fluid into the well to form a fracture pool 22 in the formation and after determining the extent of the pool sinking a further well 24 into the pool while maintaining the pool under a positive pressure. Where the formation is a salt deposit the fluid may be water, brines, acidic or caustic solutions, inert hydrocarbon liquids, or inert gases, the hydrocarbon liquids and the inert gases being replaced by a salt solvent when communication between the wells is established. If the pool drifts upwardly a fracture pool 32 extending from the well 24 may be formed and the flow through the formation may be reversed. If brine or water is the fluid it can be loaded with a heavy salt component to increase its density to avoid preferential dissolving of the roof of the fracture.

[Class 38 (iv)] [See also Group XII] Fluid level, temperature, &c.-An apparatus for the continuous melting of metal ingots comprises means for automatically controlling the rate of melting in accordance with the rate at which the molten metal is withdrawn, and the supply of fresh ingots in accordance with the rate of melting. The apparatus shown comprises three independently-heated sections 3, 2 and 30, of which the first is a preheating- chamber, the second the melting-chamber, and the third for maintaining the molten metal at a desired constant temperature, e.g. by thermostatic control of the heating. The heating of the melting-chamber is controlled in accordance with the level of molten material therein through a float 18 which, when the level in the float chamber deviates from normal, actuates a valve 24 in an auxiliary gas supply through a mercury switch 20 and a relay. The upper end of the preheating-chamber 2 is closed by a flap door 8, and below this is a weighted arm 40 which normally rests on an ingot 16 but drops when the last ingot in the preheating chamber slides past it, to close a switch and energize an electromagnet 48, which opens the door 8 and simultaneously releases an ingot 44 from the feed chamber 43. The ingots are preferably fed automatically to the feed-chamber by an elevator 56 driven by a motor 59 which is started by the fall of the arm 40, the starting circuit being maintained after the lifting of the arm by a self-locking relay. In its upward movement the last empty cradle 57 lifts the slide 55 as the next cradle passes the end of the feed chamber an ingot is discharged. The slide 55 is then released and as it falls a switch in the maintaining circuit of the relay is momentarily opened and the circuit of the motor 59 is broken.

Abstract: 1280934 Transistor switching circuits LUCIFER SA 2 Oct 1970 [24 Oct 1969] 46907/70 Heading H3T A circuit for controlling the energization of separate pull-in and hold windings of an electromagnet comprises a semi-conductor element in series with each winding, that which is associated with the hold winding being made conductive after a predetermined time from closure of a main switch while that associated with the pullin winding is conductive when the other is not and vice-versa. As shown, the semi-conductive elements are thyristors, T1 for the hold winding 4 and T2 for the pull-in winding 5. When a main switch S is closed rectified but unsmoothed power on line e, f turns on T2 and hence energizes winding 5 immediately because the potential on a trigger electrode resistor R2 is close to that of line e to which it is connected via the unenergized hold winding 4. A capacitor C1 begins to charge via R1 and when its voltage reaches the breakdown level of a gas-filled tube 6 T1 is triggered on, energizing winding 4 and hence lowering the potential on R2 so that T2 turns off at the next current zero. Turn-off of T1, T2 is assisted by diodes D2, D4. Further diodes D1, D3, D5, D6 together with capacitors C2 ... C5 limit the overvoltage due to interrupting current in an inductive load. In Fig. 2 (not shown) the thyristors are replaced by transistors, the tube 6 by a semi-conductor device having a threshold voltage which acts as a Zener diode and the main switch S by a triac so that this circuit is all "solid state".
