Title: Method of and machine for centrifugal compression of gases
IPC: F04D21/00
Filed: 1956-03-02
Abstract: 786,702. Centrifugal compressors. ANCIENS ETABLISSEMENTS BRISSONNEAU ET LOTZ. March 2, 1956 [March 2, 1955], No. 6665/56. Class 110 (1). A method of compressing, a gas comprises the use of centrifugal force to impart a supersonic speed to the gas, then expanding it to increase its speed for the purpose of straightening the flow towards the radial direction, and then increasing its pressure by shock waves and by diffusion. Gas entering the compressor inlet 5 is deflected by a fixed core 16 towards the eye of the impeller A, and leaves the impeller with a supersonic absolute velocity at a small angle to the peripheral direction. The gas then passes through a vaneless annular passage B which converges slightly over an initial part of very small radial extent and thereafter diverges, so that the velocity of the gas increases, preferably to a value between 1.5 and 2.3 times the local speed of sound, and the flow is turned towards the radial direction, at an angle of the order of 50 to 70 degrees to the peripheral direction. A shock wave occurs at the outlet of the passage B, considerably increasing the pressure of the gas and reducing the velocity to a subsonic value. A further pressure increase occurs in a bladed diffuser C. The shaft bearings 8 are carried by a sleeve 7 which is fitted into a cylindrical barrel 6.

Title: Supplying gas from compressed gas cylinders
IPC: F17C13/04
Filed: 1948-03-04
Abstract: 658,516. Storing gases under pressure. SMITH, H. ELWELL-. March 4, 1948, No. 6790. [Class 8(ii)] [Also in Group XXIX] A device for ensuring continuity of supply of gas from cylinders including a valve for each of two cylinders and a diaphragm or piston which operates to close the valve of the cylinder in use and open the valve of the other cylinder when the cylinder in use is nearly exhausted is also provided with two superimposed signs the upper one 17 being operated automatically with the supply valves and showing which cylinder is in use, and the lower one 20 being operated when an empty cylinder is replaced by a full one to bring an "EMPTY" sign beneath a visible "IN USE" sign. Fig. 1 shows a cylinder 1 with connections 3, 4 to the two gas cylinders, a central connection 2 to the consuming apparatus, and a connection 5 to a fluid pressure operated indicator 12, Fig. 5. The cylinder 1 contains a piston 6 with cup leathers 7 and rubber sealing rings 8, which seat alternately on rims 9, 10 projecting from the connections 3, 4. Springs 11 tend to hold the valves or sealing rings 8 from the seating rims 9, 10. Fig. 2 shows a modification comprising a casing with a chamber 22 divided by a diaphragm 23 carrying valves 33, 34 on its opposite sides. The valves seat alternately so as to close the connection 25 to one of the gas cylinders and a passage 29 leading to a connection 24 to the consuming apparatus and open a connection 26 to the other gas cylinder and a passage 30 also leading to the connection 24, or to open the connection 25 and passage 29 and close the connection 26 and passage 30. The casing has a connection 35 to a fiuid-pressure operated indicator. The indicator Fig. 5 comprises a casing 12 with a conduit 14 opening into a spring- loaded bellows 13 which rocks a spindle 16 carrying an indicator plate 17. The plate 17 has arms at an angle somewhat less than 180 degrees and each bearing the legend " IN USE so that the legends are alternately visible through diametrically opposite windows 18, 19. A further indicator plate 20 bearing on opposite sides reversely arranged legends " FULL," " EMPTY " may be rocked about the spindle 16 by a finger lever 21. When a cylinder is exhausted, the indicator plate 17 is automatically rocked so that the " IN USE " legend disappears from one of the windows say 18, revealing an " EMPTY " legend, whilst the other " IN USE " legend obscures the " FULL legend in the other window 19. When the used cylinder is replaced the operator switches over the lever 21 to show the " FULL" legend in the window 18. The indicator may be operated magnetically. Thus the piston 6 may be a magnet operating in a cylinder 1 of non-magnetic material and co-operating with an armature on the spindle 16. Alternately the piston may form the armature of a magnet pivoted outside the cylinder.
