...Since the combustion gases start their work cycle at extremely high pressure and temperature, the thermal efficiency of the engine (the amount of mechanical energy that it gets out of the fuel) can be very good. It has no flywheel, crankshaft or connecting rods. It has many valves to shunt air through the various chambers, but they are all self-operating, and none are exposed to high temperature. The engine can be made to run on almost any combustible liquid, even thick black bunker oil. Since the gases that spin the turbine have been mixed with scavenging air, they...
...Blue babies. The Blalock-Taussig operation, with later modifications, is relatively safe but does not correct the underlying defects; it merely seeks to counteract them by adding an abnormal blood shunt. Young enthusiasts believe that an effort should be made to correct the abnormalities (open the pulmonary valve, close the interventricular defect and thus correct the overriding of the aorta). But deaths during and soon after operations of this type, with the heart-lung machine...
Another coronary operation, as practiced by Washington's Hufnagel, involves cutting and tying off both mammary arteries-the chest wall can get along without their blood supply-and thus shunt their contents over into the coronaries. Hufnagel hit on this theory by chance when, during different cardiac operations, mammary arteries were cut accidentally, and patients made better recoveries. Hufnagel has been doing this type of operation for years, is still patiently compiling data on his patients' progress before making claims of its effectiveness. Virtually the same operation, though done in execution of a different theory, attracted wide...
Instead of the old four-track main line, the Central's electronic system needs just two tracks, will be able to shunt swift express trains around rumbling freights by cross-over switches every seven miles, also step up the speed of freight trains from 30 to 60 m.p.h. The dispatchers can also send passenger trains hurtling east and west at 80 m.p.h. on the same track, switch one to the opposite track to pass. Cost of the Central's electronic progress: $6,238,000 for the first step, as much as $50 million by the time it extends...
...most damaging of the sales tricks is auto bootlegging. While comparatively few dealers resort to it, it has a widespread effect on the trade. To get rid of unsold cars, bootlegging dealers shunt them off to used-car dealers at bargain prices (as much as 24% below list). The cars are then put on sale at near-wholesale prices, thus undercutting new-car sales. In the resulting price chaos, local new-car dealers are forced to whack their own prices drastically or offer fantastic lures to sell their goods...
