Title: Improvements in or relating to valve amplifiers
IPC: G05D3/14
Filed: 1949-07-01
Abstract: 658,167. Valve amplifying circuits. BRITISH THOMSON-HOUSTON CO., Ltd. July 1, 1949, No. 17485. Convention date, July 1, 1948. [Class 40 (vi)] An A.C. operated push-pull amplifier is arranged to discriminate against signals occurring in quadrature with the supply by employing as bias for the valves either a large A.C. in phase with the supply plus a large D.C. or rectified A.C. in quadrature with the supply. The circuits are particularly applicable to systems employing amplifiers where the desired signal varies in amplitude but is either in phase or 180 degrees out of phase with the supply. The valves 1, 2, Fig. 7, are given a large negative bias by battery Ec which is neutralized by a corresponding alternating potential developed across the secondary of transformer 24. The valves are thus sensitized only near the peak of the anode potential, Figs. 8, 9 and 10 (not shown). In a modification, Fig. 11 (not shown), the alternating potential across the secondary of the transformer is rectified to supply the D.C. bias. In a further modification, Fig. 12, the A.C. fed to transformer 30 is in quadrature to that used for the anode supply. The valves 1, 2 are thus sensitized at the peak of the cusps formed by the diodes 35 conducting, which occur at the peaks of the anode supply, Fig. 13 (not shown).

Title: Method and apparatus for controlling the injection of flux into a steelmaking vessel
IPC: C21C5/52
Filed: 1974-04-24
Abstract: 1467143 Controlling injection of flux into a steel making vessel USS ENGS & CONSULTANTS Inc 24 April 1974 [25 April 1973] 17944/74 Heading F4B [Also in Division C7] Flux from a tank 12a is injected into a steel making vessel 210 at a controlled rate. An oxygen source 2 supplies oxygen through a main line 4 to the bottom of the vessel 210. The source 2 also supplies a branch line 6, 6<SP>1</SP>, 6 which rejoins the main line at C. The branch line is supplied with flux from the tank 12a through an injection nozzle 16. Pressure to force the flux from the tank is provided by oxygen supplied through a pressurizing line 22. The difference between the pressure in the flux tank and in the main line 4 is measured by a device 40. A voltage output from the device is fed to a control 42 which controls the pressure in the flux tank as a function of the pressure differential. The pressure differential may be kept constant to provide a constant flux injection rate. The pressure in the tank is adjusted by control of valves 26, 32 in the pressurizing and vent lines 22, 28. The weight of flux in the tank is measured by load cells 34. A signal (I), Fig. 4 (not shown), indicative of the weight is fed both to (a) circuitry illustrated in Fig. 5 (not shown) concerned with controlling the total amount of flux supplied from the tank through valve 20 and (b) circuitry illustrated in Fig. 6 (not shown) concerned with controlling the flux flow rate. A signal (O 3 ) from the Fig. 6 circuitry is fed to the differential pressure flow control 42; the control 42 being illustrated in more detail in Fig. 3 (not shown). Operation of valves is such that the flux tank is pressurized and oxygen flow is established in the branch line before the flux is supplied to the branch line. The apparatus includes flux tanks additional to the tank 12a all of which are connected to the same steel making vessel. For shutting off one tank and actuating another, there is a remote switching control device as illustrated in Figs. 7 and 7a (not shown) at 70A and 70B. The steel making process may be carried out in a converter, electric furnace, open hearth or hot metal mixer.

Title: Improvements in or relating to distributors for delivering liquids or semi-liquids under pressure to a number of points
Inventor: MOORES JOHN ROBERT
IPC: F16N25/02
Filed: 1950-07-20
Abstract: 689,058. Lubricating. WAKEFIELD & CO., C. C. May 18, 1951 [July 20, 1950], No. 18110/50. Class 12 (iii). A distributer is provided with two cylinders 10, 11, in which plungers 12 and 13 reciprocate, and an inlet passage communicating by means of branch supply passages 46, 47 with ports 18, 19 in the cylinder 10, and by means of similar passages with ports 20, 21 in cylinder 11. In operation, Fig. 5, the supply port 19 communicates through a groove 15 in the plunger 12 with the top of cylinder 11 so that the plunger 13 is urged downwardly to force liquid in the bottom of the cylinder 11 through passages 28 and groove 14 to the delivery port 22. The plunger 13 at the end of its stroke, Fig. 6, opens up supply of liquid from port 21 to the port 60 in the'bottom of cylinder 10. At the same time the conduit 34 at the top of cylinder 10 is placed in communication with the delivery port 24. When the plunger 12 moves upwardly to the Fig. 7 position under the pressure of liquid in the bottom of 10, the liquid in the top of that cylinder is forced out along 34 to the port 24. The movement of the plunger 12 brings the supply port 18 into register with the crosspassage 14 whereby fluid under pressure is delivered via 28 to the bottom of cylinder 11. At the same time the passage 31 is opened to the delivery port 23. Thus the plunger 13 is caused to move upwardly to discharge liquid through 31 and port 23. The plunger in so moving places the supply port 20 in register with the conduit 34, and the bottom of the cylinder 10 is placed in communication via conduit 37 with the delivery port 25, whereupon the plunger 12 moves into position to repeat the cycle. Detent means 66 are provided for retaining a plunger at an end of its cylinder until such time as the pressure is built up at that end sufficient to overcome the detent, or alternatively a plunger may be locked at one end of the cylinder by a device controlled by movement of the other plunger.
