In a cylinder block of an internal combustion engine, a water jacket in which coolant is circulated is formed around cylinder bores. The pickup includes a pair of large crop converging augers situated along a common axis, one each on opposing sides of the crop inlet, and forwardly adjacent to the bale chamber infeed throat. The logic circuit section includes an IO power consuming circuit which uses the IO power source cell as a power source. In the second laminated portion, the refractive indices of the high refractive index layers are substantially equal to the highest refractive index of the high refractive index layers constituting the first laminated portion. Additionally, a fully cured material can be used to generate thermal energy and thereby serve as a heat blanket that can be used to de-ice aircraft. The plunger may include a plunger head located at a first end of the plunger, where the plunger is in the first position if the viscous fluid impinges against the plunger head.
