NEW EQUIPMENT mechanical-power takeoff, and marine pro pulsion. At shown, design Is marked by (all enclosure. Cylinder heads art cast o! Meehaafte, cylinder block la welded steel, furnace stress-relieved, sod liners are wearresisting Iron. Pistons are forged of 'aluminum and crankshaft of alloy steel. Bearings are precision type. Jumpers be tween head and block are claimed to pre vent leaks into the combustion space; eooling water pataca around liner over entire area of piston-ring travel. . . Intake and exhaust valves are all aame size; valve gear ia arranged so It doesn't have to be removed for cylinder-head lightening. Rods can be taken out with out removing cylinder liners. All working ports ere. readily accessible through crankpit covers. Over-all height Is 6 It 7$ in., width 4 (t 3} in,, and length 11 (t 2) in. (or 6 cylinder* and 13 ft 5} in. for 8 cylinders.

Oil-Well Meter E306 A 3-phase. squirrel-cage Life-Line induc tion motor is provided with self-sealed, pre lubricated ball bearings offering protec tive lubrication for five years or longer without repacking. Typo CSP motor is available for 60 cycles, 3 phases, 220440 v, 900-1800 rpm, from | to 15 hp. WestInghouse Eleetrie Corp, P O Box 868, Pittsburgh 30, Pa. AlJ-Weether Turbine E507 New all-weather general-purpose turbine Types for driving industrial pumps, ions, blowers, paper machinery and email gen erators is available in 16-, 20- and 2S-in. wheel sites to develop S to 1SOO hp with steam up to 600 prig, 750 F, and speeds from 1000 to 7000 rptn. With heavy-duty parts turbine can use 1500-prig 950-F steam. Many pans are interchangeable between wheel tites. Combination felt and labyrinth bearing seals protect lubricating system from con tamination by heavy rain and abrasive dust Corrosion-resistant materials are used throughout An overspeed trip simultaneously controls governor valve and a heavy butterfly valve. An improved fiee-espanston center-line support transmits pipeline reaction to the foundation. Entire governor assembly mounted on shaft end protected by caring can be replaced without disturbing shaft. . Governor Is interchongeable between wheel site*. Specie! wide-speed-renge governors are available. Westlnghouse * Electric Corp, P O Box 866, Pittsburgh 30, Pa.

However, this much can be stated autborita- finely; there are three Revere Metals which deserve ? fpecial consideration in cases of limited or unsatis* factory tube life. Here they are: Cupro-Nickel, 30%. Withstands high operating temperatures. A tenacious surface fUm forms on this metal, which resists impingement attack and erosion, salt water, and waters containing organic material. Widely used In marine and seaboord installations, the tropics ond sub tropics. Cupro-NIdtel, 30%. Similar to Cupro-Nickel, 30%, but lower In price and somewhat less resistant to certain types of corrosion. lisa.convenient reply cords on page 202o to sacuro additional Information on those now oqnlpment Items- N**** ^ sara to identify your request with th* naw-equlpment hey Uttar, ff, ond number, os shown on tha Item* she*** Revalon (Aluminum 8rati).
