Title: Improvements in or relating to wet gas meters
IPC: G01F3/30
Filed: 1929-03-09
Abstract: 329,069. Mautner, A., and Mautner, M., (trading as Mautner & Co., A.), Marischka, C., and Brandl, H. March 9, 1929. Gas meters.-In a wet gas meter of the type in which a tumbling or swash plate movement is imparted to a partitioned bell by the passage of the gas, the bell is divided by partitions in two groups of compartments into which pipes leading from chambers in the sealing liquid project, and inflow and outflow of the gas into the compartmonts is controlled by the movement of the bell. In the construction shown in Figs. 1 and 2, the bell is formed with three circular partitions 11, 12, 13 concentric with the curved outer wall 10, the space between the wall 10 and partitions 13 being divided by radial partitions into six compartments I, II - - VI and the space between the partitions 11, 13, being divided into twelve compartments I<1>, I<11>; II<1>, II<11> - - VI<1>, VI<11>. The gas inlet pipe 15 is surrounded by three annular chambers 21, 22, 23 each of which is divided into two sections by a central partition such as 25, Fig. 4. From each half of the chambers 21, 22, 23, three pipes extend upwardly, one pipe as d extending into one of the six compartments I - - VI and two pipes as d<1>, d<2> extending between the partitions 12, 13 into the compartments P, I<11>, - - VI<1>, VI". The bell is carried by an inclined spindle 5 supported in a ball and cup bearing 8 above the inlet pipe 15, the spindle moving over a conical surface during the operation of the bell and operating a crank 3 on the vertically adjustable driving spindle 2 of the counting mechanism. The partition 11 its formed with six apertures 27 allowing the passage of gas from the inlet pipe 15 to the compartments I" - - VI<11> and the top of the bell is formed with six apertures 28 allowing gas to issue from the compartments I<1> - - VI' into the space surrounding the bell, from which space the gas passes to the discharge pipe 29. The partition 12 is shorter than the partitions 11, 13 and the wall 10 so that while the latter always dip into the liquid seal the edge of the former is on one side of the meter above and on the other below the level of the liquid seal. In operation, gas flows from the inlet pipe through the apertures 27 into a compartment such as IV", Fig. 1, ir which the partition 12 is above the liquid seal and then passes under the partition' through the pipe d<2>, chamber 22 and pipes d, d<1> to the chambers IV, IV<1> thereby causing the movement of the bell. When the bell has moved so that the partition 12 is above the liquid seal in the compartment IV', it is below the liquid seal in the compartment IV<11> and gas passes from the compartments IV, IV" to the compartment IV<1> and under the partition 12 to the exit 28. The meter may be calibrated by altering the obliquity of the bell. The meter may be modified by providing pipes projecting upwards into the sectors and connected discharge piping instead of the holes 28 and by guiding the bell spindle in a vertically adjustable circular track arranged above the bearing 8.

Title: Improvement in electrostatic machines
IPC: H02N1/08
Filed: 1948-03-16
Abstract: 655,474. Electrostatic machines. CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE. March 16, 1948, No. 7911. Convention date, March 21, 1947. [Class 35] The movable charge carrying members of an electrostatic machine are formed of mutually insulated conducting bars whose cross-section is of uniformly convex outline and whose longitudinal axis extends perpendicularly to their direction of motion, at least two of the stationary charge inducing members being wide enough to span several movable members at once. The conducting bars, which may be of round, elliptical or oval section, may be arranged as a series of radially extending blades or they may lie axially to form a " squirrelcage ". A machine of the latter type, Fig. 2, comprises a series of round section bars a extending between two insulating end flanges b. The ends of the bars are contacted by brushes i, j. The stator comprises an insulating ring d having inserted, in its internal face, a pair of main charge inducing members f, g spanning several rotor bars, and a series of intermediate bars e of round or asymmetrical shape situated between them. Resistances h interconnect successive stationary bars so that the potential varies uniformly around the stator, the terminals f, g being maintained at different potentials, e.g. by auxiliary generators. Alternatively, the auxiliary inducing members e may be replaced by a number of plates of low conductivity material which may have a smooth or slotted inner face. The machine having radial bars, Fig. 4b, comprises three rows of bars m secured in an insulating hub k and connected to contact terminals o. The crosssection varies progressively along the bars, being an ellipse flattened in the direction of movement at the hub end, and elongated in that direction at the outer end. The stator comprises a series of semi-conducting plates p having diametrically opposite charge conducting inserts. It is advantageous to make the bar thickness at right angles to the direction of motion equal to twice the spacing between a bar and a stationary member and equal to this distance when influenced on one side only. Specification 637,434 is referred to.
