Abstract: ABSTRACT OF THE DISCLOSURE          A method is disclosed for heat treating a preheated pulverous raw material containing at least a portion of lime to produce a partial calcination prior to passing the raw material down through an inclined rotary kiln for further heat treatment. Partial calcining is accomplished by introducing into at least one end of a rotary kiln an amount of fuel sufficient for pre-heating, at least partially calcining, and substantially com-pletely sintering the raw material, at least part of the fuel being introduced into the lower material outlet end portion of the kiln.  An amount of oxygen containing gas sufficient for substantial combustion of the fuel introduced into the kiln is introduced into the lower end portion of the kiln, and preheated raw material is introduced into the mouth of the kiln in such a manner that the material is entrained in gases exiting from the kiln mouth.  The gas and entrained material exiting from the kiln are directed into a calcination chamber communicating with the upper material inlet end portion of the kiln such that the mater-ial is at least partially calcined by the contact with the kiln exit gases.  The material is thereafter separated from the kiln exit gases and reintroduced into the upper end of the kiln in a manner which permits it to pass through the kiln for further heat treatment while avoiding entrainment in the kiln exit gases.  A rotary kiln plant for practicing the method is also disclosed which provides for at least partial calcining of the material initially introduced into the kiln and thereafter reintroducing the partially calcined material in such a manner as to promote passage down through the kiln for further heat treatment.

Abstract: A B S T R A C T     A cylindrical lock has a casing mounted in a trans-verse opening in a door and includes an outer knob spindle sleeve which extends axially outwardly from the casing.  An outer rose liner received on the sleeve has spurs which engage the outer face of the door to secure it against rotation relative to the door.  A tab on the rose liner received in a groove in the sleeve prevents rotation of the sleeve and casing relative to the outer rose liner.  An outer thimble threaded onto the sleeve retains the outer rose liner and an outer rose, which covers it, in assembly with the sleeve.  A projection on the outer rose re-ceived in a recess in the outer rose liner prevents rotation of the rose relative to the rose liner.  The thimble conceals the latter connection and has a slot in its inner end which receives a portion of the locking tab to secure the thimble against ro-ration relative to the rose liner and the sleeve.

Abstract: ABSTRACT OF THE DISCLOSURE      The specification describes an improved motor control system for adjustable speed control of DC motors where the armature voltage is adjusted by phase controlled thyristors.  Previous systems have used a closed loop feedback system combined with IR compensation which require different compensation factors for high and low speeds in smaller inexpen-sive motors.  The present invention provides a pro-grammable compensation response more economically than in the prior art control circuit, and also achieves thermal compensation for holding set speeds during changing control temperatures.  This system is more immuned to malfunctions caused by momentary interruptions of supply voltages and reduces losses and heating incident to the powering of the control circuitry.  The major segements of the motor control circuitry include:  power semiconductor bridges, a pulse generator, an error comparator/amplifier, and a speed reference circuit.

Variation in output due to the variation in  ambient temperature may be minimized indepen-dently of ddrain current of MOS field-effect  transistor, and drifts due to variation in ambient temperature of equipment and instruments such as pollution detectors and recorders which are installed outdoors may be reduced to a minimum. This analog voltage memory device is used as peak hold memory, sample-and-hold memory, zero-point memory, etc. and can well hold signals for a long time to achieve a non-volatile memory in spite of no power supply.
