Abstract: ABSTRACT OF THE DISCLOSURE           An automatic control for a clothes dryer embodying microcumputer controlled apparatus adapted to maintain optimum drying efficiency with minimum risk to the clothes fabrics.  The control operates the dryer at maximum heat in-put rate and a minimum or normal low air flow rate through the drum during the initial warm-up period and the ensuing period during which the moisture removal rate is relatively constant.  During these periods, the inlet temperature is monitored and when it exceeds a "fabric-safe" level, the air flow rate is increased and the heat input is reduced preferably after an established time delay to allow conditions to stabilize in the drum after the air flow rate is increased.  The control is responsive to outlet air temperature to sense when the moisture removal begins declining to maintain the air flow at the normal low rate, selectively reducing the heat input rate only as needed as determined by the inlet air temperature for safe fabric conditions until the clothes are dry and the drying cycle is terminated.

Abstract: ABSTRACT OF THE DISCLOSURE      A switching circuit turns on at the beginning of a first clock signal and turns off in response to a gyroscope shaft detector signal.  During the time the switching circuit remains on, a counter counts the cycles of a second clock signal.  This resultant count is employed as an error signal for adjusting the output frequency of a pulse generator which is connected to a gyroscope motor.  A feedback loop is created between the aforementioned components for achieving a preselected constant gyroscope motor speed.

Abstract: ABSTRACT OF THE DISCLOSURE     This specification provides a simple closure device which is free from the disadvantages of the known closure devices but has the same reliability as that required in conventional devices of the same kind for use in ultra-centrifuges.  The specification discloses a closure device for centrifuge test tubes, comprising an insertion piece extending partially from the opening into the interior of the test tube, whereby the outer diameter of the lower part of the portion to be inserted into the tube, corresponds to the inner diameter of the tube.  The upper portion of the insertion piece, which is substantially outside the tube, has an outer diameter greater than the inner diameter of the tube and an abutment is provided outside the tube and, under the action of centrifugal force, the insertion piece presses the test-tube edge against the abutment.  Preferably, the abutment has a conical or flat annular surface concentric with the container axis.  In an embodiment of the invention, the abutment can comprise a ring which is slid from beneath over the test-tube.  In another embodiment, the abutment can be formed in the rotor itself.

Abstract: ABSTRACT OF THE DISCLOSURE          A conveying and collection system adapted for drilling rigs for conveying drill cuttings entrained with a bailing air flow stream emanating from the drillhole includes a generally tubular head fitted around the drillhole having a flow deflecting surface portion adapted to deflect the flow stream of drill cuttings into a conveying enclosure whereby velocity reduction and change of direction of the flow stream will separate relatively coarse cuttings. A mechinical conveyor may be disposed in the enclosure to convey the cuttings to a point remote from the drillhole. The head may be extended and retracted with respect to the drill rig deck plate by actuators controlled in accordance with the conduction of bailing air to the drill stem. One embodiment of the head comprises an enclosure formed by overlapping helical convolutions of a flat spirally coiled band. The head may be provided with retractable gate members remotely actuated to move clear of an opening in the head which is of sufficient size to permit movement of drill stem coupling members and/or the drill bit through the head during drilling operations. A filter unit has a plurality of separate filter element chambers in which are disposes porous media filter elements arranged side by side along the path of a bailing air flow stream entering the filter unit housing so that the lower velocity portions of the flow stream are diverted into the filter element chambers and forced to flow in a vortical manner to provide inertial separation prior to flow through the filter elements. A suction pump on the filter unit is operable to vary its inlet volumetric capacity to provide a partial vacuum condition throughout the collection system to minimize leakage flow of dust laden bailing air out of the system.
