Abstract: A discharge cone casting for the discharge end of a rotary mill is disclosed which is integrally cast in a single component. The casting specifically consists of a generally flat base member adapted to conform to the discharge end of the mill and having converging sides, a top member having converging sides similar to those of the base member and disposed in overlying relation but also including a portion that extends beyond the base member and curving toward its plane, and an interconnecting web extending transversely between the base and top member to define a generally I-shaped cross section. Mounting bolt holes are formed through the upstanding web to enable the discharge cone casting to be bolted directly to the mill end as a single unit.

Abstract: An improved hammer comprises a hammer body with a substantially bell-shaped profile having a larger end and sides converging to a smaller end with front and back faces that are substantially flat. A large mounting bore extends through the body closer to the smaller end to receive a pivot shaft from which the hammer may pivotally swing. A lifting eye is integrally formed with the hammer body, and includes sides that extend from the sides of the hammer body, converging to a rounded apex.

Abstract: The temperature controller employs a single thermistor temperature sensor providing an analog signal indicative of engine system temperature. The analog signal is compared with a plurality of separate threshold temperatures to produce a multiplicity of separate temperature signals representing different temperature ranges across the operating temperature spectrum of the engine system. These separate temperature signals are processed through digital logic gating circuitry to provide sequentially occurring outputs on parallel output leads. The sequentially occurring outputs sequentially activate different heat dissipating mechanisms within the engine system to maintain a substantially constant temperature.

Abstract: A splice rail assembly for joining two adjacent panels in a coplanar relationship having two parallel tongues extending perpendicularly therefrom, the first of which tongues is located substantially in the mid-portion of the splice rail, the second being offset therefrom a distance substantially equal to the thickness of the first tongue. When two such rails are appropriately positioned with their tongues facing each other, the mid-portion tongues of each can be inserted into the space between the two tongues of the opposite rail in an interlocking relationship. The sides or ends of two panels fit, respectively, into the spaces formed between two such interlocked splice rails outwardly of the tongues and the resulting assembly can be fastened together with suitable fastening members.
