Abstract: ABSTRACT OF THE DISCLOSURE           A dryer for particulate material combines the drying effect of a stream of heated gas circulated by a blower in a closed duct system with that of a radiator structure which is in the drying chamber and is an a heat pump circuit.  The condenser of the heat pump circuit is in the duct system where it condenses moisture from the gas which has passed through the particulate material.  The heat pump compressor is driven by an internal combustion engine which is in a compartment in heat exchange relationship with the duct system.          The engine cooling system radiator is immediately downstream from the condensor and the engine exhaust system includes a heat exchanger which is in the duct downstream from the engine cooling radiator.

Abstract: FET LOAD GATE COMPENSATOR     Abstract of the Disclosure An FET load gate compensator employing feedback to control the load gate voltage holds the circuit delay and power dissipation of an integrated circuit nearly constant.  The integrated circuit chip is provided with several stages of inver-ters which act as a delay sensor to simulate the delay of the operational circuit on the chip.  The time delay of the delay sensor on the integrated circuit chip is compared with an ex-ternal clock reference by a delay comparator.  The delay com-parator generates an output voltage which is used to adjust the load gate voltage until the delay in the delay sensor is equal to the clock reference.  Since the same load gate voltage is distributed in the rest of the operational circuits in the in-tegrated circuit chip, the delay times of these circuits will track with that of the delay sensor and thus also tend to be held constant.

Abstract: SIGNAL DETECTION DURING VARIABLE       SPEED TAPE MOVEMENTS     Abstract of the Disclosure A signal detection arrangement is disclosed for detecting signals during variable speed tape movements such as during tape rewinding or fast forward speeds.  To elaborate, information encoded as multifrequency information tones is grouped in exercises on a recording tape, and at least two low frequency tones are provided at the beginning of each exercise.  Each of these low frequency tones has a frequency which is related to the frequency of a different one of the information tones by a multiple of the ratio of the rewind speed to the normal forward speed times a predetermined factor.          Accordingly, during normal playback these low frequency tones will not be detected.  However, during fast forward or rewind, each of these tones will be multiplied up to a detectable frequency.  Moreover, even over wide variations in these "fast" speeds, at least one of these low frequency tones will be detected.

The lower spindle includes a clamping mechanism having a screw means for drawing the upper spindle toward the lower spindle and the lower spindle toward the upper spindle to clamp the blank to be split therebetween.  Bearing means are disposed between the frame and the spindle assembly for supporting the spindle assembly for rotation.  The clamping means are operative to exert a clamping force between the upper and lower spindles which is isolated from the frame and the bearing means to clamp a blank therebetween.  A pair of rotatable tools are provided each of which has an axis of rotation parallel to the axis of rotation of the spindle assembly and each of which is associated with a motor means to effect rotation of the tools.  The tools are operable to move relative to the blank supported by the spindle assembly to effect sequential engagement between the tools and the peripheral edge of the blank to sequentially split and form the blank.  Control means is provided for controlling the speed of the spindle to match the peripheral speed of the rotating blank supporting by the spindle with the peripheral speed of the tool with which it is desired to engage the blank.  The control means senses the speed of the first tool to be engaged with the rotating blank and controls the speed of the s[indle in response to the speed of the first tool and subsequently senses the speed of the second tool to be engaged with the blank and controls the speed of the spindle in response to the speed of the second tool.  The speed con-trol of the peripheral speed of the tools and the rotatinf blank prevents skidding of the tools upon initial engagement of the blank with the tools,
