Abstract: Abstract of the Disclosure A charging shaft in a furnace housing, communicating at its bottom with an adjoining combustion chamber, is topped by a sloping lid having an air-intake opening near its lower end, that opening registering with an underlying baffle defining with that lid a narrow rising channel for incoming air.  Distillation gases evolving in the shaft, admixed with some of the entering air but prevented by that air from es-caping through the channel, are recirculated through a port at the top of the shaft to an entrance near its bottom --just above a horizontal grate-- by way of an adjacent duct provided with a lateral air inlet, the duct narrowing at that inlet into a constricted throat from which the recirculated gases are aspirated by the entering additional air.  The connection between the charging shaft and the combustion chamber may be formed by an upright grill, or by a diverging passage accom-modating an ancillary combustion device such as an oil burner.          The channel and the duct are separated by a water-cooled partition.

Abstract: Patent Specification Entitled "COATING APPLICATOR"                   Abstract of the Disclosure A coating applicator for applying a layer of coating material around the circumference of a portion of an elon-gated shaft, such as a bolt.  The applicator includes a chamber which is filled with coating material and has an opening for receiving the elongated member.  The opening in the chamber has a cross-sectional dimension just slightly larger than the elongated member.  A cover arranged within the chamber in sealing contact with the opening prevents leakage of coating material.  This cover is retractable upon insertion of the elongated member into the chamber.  Coating material then totally surrounds and coats the entire circum-ference of a limited longitudinal portion of the elongated member.  The coated elongated member is subsequently removed from the chamber.  As the elongated member is removed, the inner walls of the chamber which define the opening serve to remove excess coating material from the member and to smooth the layer of coating material.

Abstract: ABSTRACT OF THE DISCLOSURE      A measuring-while-drilling system includes motor speed detection during encoding for returning control to a phase locked loop circuit when the rate of an acoustic signal generator has precisely returned to a carrier frequency producing rate.  The measuring-while-drilling system includes the acoustic generator which has a moveable member disposed within the flow of drilling fluid and which is driven at speeds for imparting to the drilling fluid an acoustic signal having phase states representative of encoded data signals derived from measured downhole conditions.  The phase locked loop circuit drives the moveable member at a substantially constant rate to thereby effect a substan-tially constant carrier frequency in the acoustic signal. A frequency changing control circuit is provided for tempo-rarily changing the rate of the member to effect a predeter-mined phase change in the carrier signal according to the data.  The rate of movement of the member is changed in a first direction until a prescribed amount of the predeter-mined phase change is achieved, and the rate of movement is changed in the opposite direction for accumulating the remainder of the predetermined phase change.  A rate detec-tion circuit monitors a signal representing the rate of movement of the member for generating an end-of-return signal which stops the rate of movement in the opposite direction precisely when the rate of the member has been returned to the constant frequency producing rate.
