1917 Woods Twin Power
The primary hybrid gas electric automobile didn't come out in 1983, but in 1917. The Woods Twin Power was built by the Woods Motor Vehicle Company of Chicago. Because the gas engine was therefore rough, however supplied more power and electrical cars were smoother, but had limited vary, the Woods Motor Vehicle Company wanted to provide a automotive that gave you the most effective of each worlds.
The most effective half is, it was a full hybrid (listen up GM) with regenerative braking. The engine was a parallel hybrid that included a 12-hp, four-cylinder gasoline engine as an auxiliary drive system additionally to the electric drive train. The electric engine may propel the automotive up to twenty mph. Together with the gas engine, the twin wood power may stand up to 35 mph.
The gas engine and electric engine were connected using a magnetic clutch. The gas engine became magnetized when activated (by a lever controlled by the motive force). The copper disk was pulled against the flywheel connecting the electric motor to the gas engine.
Only the electric motor might be used whereas moving into reverse. Why? As a result of the engine had no clutch and thus the gas engine had no gears!
The automotive battery designed for this car was about half the dimensions of the batteries in different electric cars of the time. Once the automobile got up to twenty mph, the gas engine could be engaged, allowing the electric motor and gas motor to figure together. The battery could be recharged or discharged by another lever. Recharging was done by the gas motor (at speeds over 6 mph) or by braking on level ground or when coasting down hills. A typical brake pedal was only used at speeds of less than 6 mph.
Offered for solely $2650 (bear in mind this was 1917). Wire wheels were a luxury, costing an extra $25. Or you'll 'pimp' your vehicle out for another $100 (paint and trim).
Ultimately, the first hybrid was a commercial failure. It had been engineered solely in 1917 and 1918. It was too expensive, too slow, and too troublesome to service to be a commercial success.

what is the difference between Diaphragm and Bellow type differential Pressure gauges?
#In gauges intended to sense small pressures or pressure differences, or require that an absolute pressure be measured, the gear train and needle may be driven by an enclosed and sealed bellows chamber, called an aneroid, which means "without liquid". (Early barometers used a column of liquid such as water or the liquid metal mercury suspended by a vacuum.) This bellows configuration is used in aneroid barometers (barometers with an indicating needle and dial card), altimeters, altitude recording barographs, and the altitude telemetry instruments used in weather balloon radiosondes. These devices use the sealed chamber as a reference pressure and are driven by the external pressure. Other sensitive aircraft instruments such as air speed indicators and rate of climb indicators (variometers) have connections both to the internal part of the aneroid chamber and to an external enclosing chamber.
#The Diaphragm Pressure Gage uses the elastic deformation of a diaphragm (i.e. membrane) instead of a liquid level to measure the difference between an unknown pressure and a reference pressure.
A typical Diaphragm pressure gage contains a capsule divided by a diaphragm, One side of the diaphragm is open to the external targeted pressure, PExt, and the other side is connected to a known pressure, PRef,. The pressure difference, PExt - PRef, mechanically deflects the diaphragm.
*Pros:
- Much faster frequency response than U tubes.
- Accuracy up to ±0.5% of full scale.
- Good linearity when the deflection is no larger than the order of the diaphragm thickness.
