Abstract: A detachable ramp carrying system for moving containers including a pair of securement brackets coupled with the horizontal lower segments of opposed L-shaped brackets of the moving container. The securement brackets support the ramp thereon disposed below the closed lower end of the container.

Abstract: A prefabricated modular wall element (20) comprises a precast reinforced concrete wall panel (21) having a front face (24). A plurality of spaced-apart individual slabs (33) of stone or brick are partially embedded in the front face (24) of the panel (21) during casting of the panel (21) and project outwardly of the front face (24) with channels being formed between the slabs (33). The slabs are arranged on the front face (24) such that the front face (24) simulates a wall constructed of stone. A pair of spaced-apart support legs (38) are provided at a bottom (27) of the wall panel (21) for keying into a concrete foundation (42) to support the wall element (1) in an upright position.

Abstract: Apparatus for and method of determining the brake torque and horsepower of an internal combustion engine without connecting an external load. Means are provided to operate the engine at full throttle and with all but one out of n of successive ignitions inhibited, the value n being selected so that the engine operates with just enough power to equal the frictional load of the engine and maintain an equilibrium speed at the upper end of the engine speed range. The engine is then operated momentarily with full ignition, and then with no ignition, during which a determination is made of the rate at which the engine decelerates through the equilibrium speed. The deceleration rate is multiplied by the known inertia of the engine to determine the friction torque of the engine at the equilibrium speed. The friction torque is multiplied by n - 1 to predict the brake torque of the engine at the equilibrium speed when operated normally with external load. Horsepower is determined by multiplying torque and speed.

Abstract: Satisfactory or unsatisfactory engine compression is diagnosed by comparing the amplitude of the starter motor current, when cranking an engine having its ignition inhibited, with a reference value. The reference value is adjusted in accordance with the intake manifold absolute pressure, as determined from measurements during the test of ambient pressure and intake manifold vacuum.

Abstract: Means for and method of testing the power of an internal combustion engine. A tachometer means coupled to the engine generates one electrical pulse per engine cycle of the engine. While the engine is full-throttle accelerated, a computer means measures the time periods between successive pulses, each time period constituting the reciprocal of the average engine speed during the particular engine cycle. One-half of the time period corresponding with a low speed and one-half of the time period corresponding with a high speed are added to the intermediate time periods to determine an acceleration time period which is a measure of engine power. The acceleration rate is determined by subtracting the reciprocal of the time period corresponding with the low speed from the reciprocal of the time period corresponding with the high speed to determine the speed change, and dividing the speed change by the acceleration time period.
