Abstract: A B S T R A C T          Fail safe electromagnetic clutch (10) includes a driving member (12) and a driven member (16).  Engagement structure (30) cushions engagement between the driving member (12) and driven member (16) when the clutch is engaged.  The engagement structure (30) includes a pair of elements (36, 34) and a resilient wave washer (42) located therebetween.  The waver washer (42) biases the element (36) into driving engagement with the driving member (12) and biases the element (34) into driving engagement with the driven member (16). When the clutch is disengaged, a magnetic coil (22) forces the element (34) away from the driven member (16), thereby collapsing the wave washer (42).  When the clutch is to be re-engaged, the coil (22) is de-energized, thereby permitting the wave washer (42) to drive the element (34) back into driving engagement with the driven member (16). Accordingly, there is a conical clutching surface between the engage-ment structure (30) and the driven member (16) and a disc engagement surface between the engagement structure (30) and the driving member (12).  Therefore, upon engagement of the clutch, the conical engage-ment surface (50, 52) slips briefly, and the disc engagement surfaces (37, 39) slip until the clutch is fully engaged, thereby cushioning engagement of the clutch to minimize the inertial shock that would otherwise occur when the clutch (10) is engaged.

Abstract: Method and apparatus for regulating the heat transfer coefficient between a granular material and an exchange surface inside a heat exchanger in which a descending flow of a charge of material is arranged in the form of a mobile bed in contact with an elongated exchange member extending between lower and upper levels of the tank of the exchanger. The latter is provided with injection means for a gas into the charge of material. The flow conditions of the gas passing through the charge from below upwards are regulated so that the ascending flow speed is initially less than, at the base of the tank, the critical fluidization speed and then increases gradually to reach such critical speed at an adjustable level comprised between the lower and upper levels of the exchange member. The invention is especially applicable to heat exchangers used for cooling a granular material and/or for the heating of a heat transfer fluid.

Abstract: ABSTRACT      The control loading system described is capable of higher performance than anything available hereto-for because of certain described features built in.          The control loading system that is described includes a force transducer to develop an electrical signal corresponding to the force applied to the manually-operable controls of a vehicle simulator to develop a "feel" as sensed by an operator that matches the real world response of actual controls.  A computer generates an electrical signal corresponding to the force required for these controls to give these realistic cues.  A compare circuit generates a signal corresponding to the difference between the applied force and the re-quired force, and the usual actuator device develops a force on the manually-operable vehicle controls in response to this difference signal.  One of the more significant features of the invention is the monitor which detects deviations in force magnitude to disable the control loading system when the force detected exceeds a pre-set limit.
