摘要： 8614. Ehrhart, R. N. April 21, 1905, [date applied for under Patents Act, 1901]. Elastic-fluid turbines.-The fixed and moving blades of a turbine or compressor are secured by means of a corrugated shank 12, Fig. 6, held against the wheel 14, Fig. 3, by a ring 19. A screw passes through the screw holes 20, 11, 15. The wheel and holding - piece 19 are suitably grooved to hold the shank, the end 10 of which is, in the case of the moving blades, bent as shown. Spacing-pieces 31 are provided, which, in a modified form, fit into holes in the blades.

摘要： 14,793. Ehrhart, R. N. July 2, 1913, [Convention date]. Straight tubes between headers or connecting- boxes. -The condenser is horizontally disposed and comprises the nest of tubes 4 within the casing 1 to which the fluid to be condensed, for instance steam, is admitted by the inlet 6 d, when condensed, is discharged by the outlet 9. The nest of tubes is situated eccentrically so that the steam is admitted substantially around the entire perimeter and that any liquid of condensation falling from the tubes passes through uncondensed steam in the steam space on its way to the outlet 9. Condensing-water entering the chamber 15 passes through the central tubes 20 and returns by the outer rings of tubes 21 to the annular chamber, which opens to the discharge port 14. Air or non-condensable fluid passes away by the upwardly extending chamber 7 which extends the length of the condenser, any liquid which may be entrapped there in passing away by the pipe 10.

摘要： 8489. Ehrhart, R. N. April 12, 1905, [date applied for under Patents Act, 1901]. Elastic-fluid turbines.-An elastic-fluid turbine in which the high-pressure stage is a velocity element and the low pressure stage a pressure element is shown in Figs. 1 and 2. Duplex admission nozzles 1 expand the steam down to the exhaust pressure, and a fraction of its velocity - energy is absorbed by a row of impulse blades 2. The steam is then guided by blades 5 into a transforming-chamber 3, where its velocity-energy is converted into pressure-energy, and it is then fractionally expanded as it passes through a series of ordinary reaction blades 6. Between the transforming chamber 3 and the impulse and reaction blading 6 a section of blading may be interposed to utilize a portion of the fluid energy in the form of velocity.

摘要： 1,159,306. Discharge lamps. J. W. HARRISON and R. N. FOXGORD. 24 April, 1967 [2 Aug., 1966], No. 18854/67. Heading H1D. [Also in Division H5] In fluid sterilization apparatus (see Division H5) comprising a chamber through which fluid to be sterilized passes, having a lamp projecting into the chamber and being adapted to emit ultra-violet rays to irradiate the fluid, the lamp projecting through a wall of the chamber, a fluid tight sealing means is fitted between the wall and the lamp and comprises a mouldedin-place seal of resilent material which adheres to the surface of the lamp. The preferred material is silicone rubber. Preferably as shown the lamp is tubular, the chamber 11 being elongated with the lamp 12 supported centrally in it by the interaction of mouldedin-place gaskets 48 and annular elements 49, 52 which by means of screws 53 are tightly clamped on the gasket. In alternative sealing arrangements, Figs. 9 to 11 (not shown), the moulded-on seal is provided on its face facing away from the chamber 11 with an apertured disc bonded to it. A locating means comprising a removable retaining ring is provided in a groove in the housing to locate the lamp. The seal may have concave or cup-shaped inner surfaces so that the pressure of the fluid in the chamber tends to force the seal against the wall. Alternative locating means (Fig. 10) comprises a sleeve which co-operates with a threaded cap 54 to locate the tube 12. An 0 ring may be fitted in to a groove around the sleeve and disc to complete the seal. In Fig. 11, the disc is replaced by a cylindrical member into a central orifice in which the moulded-in-place seal fits. The cylindrical member is positioned by means of a sleeve and threaded cap and sealed by an 0 ring as in the previous alternative.

摘要： 6408. Ehrhart, R. N. March 19,1906, [date applied for under Patents Act, 1901]. Elastic fluid turbines.-A governing-mechanism for elastic-fluid turbines is shown in the Figure. A governor-controlled puff-action throttle valve 9 supplies steam to the steam-chest 5. The nozzles are arranged in groups, the first group 6 opening into the steam-chest ; the second group 7, the third group 8, and other groups, if there are any, are controlled by valves 19. The first valve 19 is normally closed but is opened when, owing to a diminution in the speed of the turbine, the more fully opened throttle valve supplies more steam than can be readily passed through the first group of nozzles, so that the increased pressure in the steam-chest, passing through a pipe 29, acts underneath the piston 24 of the valve 19 and raises the valve. The top of the piston 24 is ac'ed on by a spring 28, and by a reduced pressure introduced through a pipe 26. A second piston 23 on the valve-rod 20 is acted on underneath by the pressure in the steam-chest, and on the top by the pressure in the nozzle chamber 17 passing through a pipe 31. The second valve 19 is actuated in a similar way except that its actuating-fluid is supplied by a pipe 33 connected to the first nozzle chamber 17, and the valve comes into action when the first valve is overloaded. Subsequent valves are similarly actuated. The valves close in the reverse order.
