Abstract: ABSTRACT OF THE DISCLOSURE Fibrous materials and manufactured articles which are washable, preferably in the form of damp laundry, are softened by being tumbled against a fabric conditioning article comprising a base and a coating thereon which includes either a nonionic surface active conditioning agent or a water soluble anionic surface active conditioning agent or a mixture thereof.  The coating is transferable to the fibrous materials under the conditions of operation, usually in the presence of moisture and heat in an automatic laundry dryer, and the tumbling is continued for a period of time long enough to apply to the fibrous materials to be treated a coating of the conditioning substance sufficient to accomplish the desired conditioning.  A portion of the softening substance penetrates the base and constitutes 10 to 30% of the portion exterior of the base.  Preferred compositions of the coating include poly-lower alkoxy-containing compounds of molecular weights of from 300 to 6,000, which contain hydrophilic and lipophilic groups in balance and which are surface active, together with alkali metal higher fatty alcohol sulfates. Particularly preferred compositions comprise higher fatty acid mono-lower alkanolamides and higher fatty acid di-lower alkanolamides.  These compositions are preferably coated onto form-retaining bases.

Abstract: ABSTRACT OF THE DISCLOSURE          An electrically powered, two wheeled hand truck having telescoping frame parts, the inner frame part being raised and lowered by electric power means in the form of a rotatable screw shaft which engages a bearing nut fixed to the inner movable frame part.  Rotation of the screw in a particular direction either lowers or raise  the inner frame part. A DC motor is carried by the hand truck and powered by a battery voltage source also carried by the hand truck.  Electrical switching means select the direction of rotation of the screw shaft for lowering or raising the inner movable frame part.  Rapid and accurately controlled raising and lowering allows moving a load carried on the movable frame part from a raised position to a lowered position and vice-versa.  A braking means holds the screw shaft when the motor is turned off so that the load does not slip. Starting the motor overrides the braking means to either raise or lower the load.

A second comparison means is arranged to compare signal intensities received on the right-hand and left-hand lobe systems. A second indicator is arranged to indicate the output signals of said second comparison means. Said right-hand and left-hand lobes comprising said lobe systems are arranged to partly overlap each other so that the maximum common signal intensity received exceeds the corresponding signal intensity received on the main antenna in the same direction.

Abstract: ABSTRACT OF THE DISCLOSURE            A meter for measuring the brightness and/or consistency of pulp slurry.  An optical probe introduces light energy into the slurry, which energy is transmitted and back-scattered, and reflected orthogonally.  Three signals are provided which correspond to the back-scattered, reflected, and transmitted energy.  Each of the signals is ratioed against a reference signal which corresponds to the intensity of the energy introduced into the slurry to provide three outputs proportional to the difference between the reference signal and the received signals.  The output corresponding to the back-scattered energy is multiplied by the log of the output corre-sponding to the transmitted energy to produce a measurement of brightness independent of consistency.  The output corre-sponding to the back-scattered energy is divided by the log of the output corresponding to the reflected energy to produce a measurement of consistency which is independent of the pulp brightness.
