Abstract: ABSTRACT OF THE DISCLOSURE       Pellets of predetermined size are produced from a finely-divided material by pelleting a damp, finely-divided material, sieving the pellets, recycling the underflow obtained by sieving to the pelleting, and feeding the overflow to a continuous-working hardening operation.  In order to even out the quantity and size distribution of the pellets a portion of the pellets is recycled, before sieving, to the pelleting;  at least a portion of the pellets separated before the sieving is directed to a storage silo before being recycled to the pelleting;  and a portion of the overflow obtained from the sieving is also recycled to the pelleting.

Abstract: PATENT APPLICATION         of RICHARD R. ERNST       for SELECTIVE DETECTION OF MULTIPLE QUANTUM TRANSISTIONS           IN NUCLEAR MAGNETIC RESONANCE               ABSTRACT OF THE DISCLOSURE    Selected orders of multiple quantum transitions may be detected by preparing a statistical non-equilibrium state of an assembly of gyromagnetic resonators of selected phase with respect to a subsequent mixing pulse.  After an evolution period, t1, a 90°  mixing pulse is applied and the free induction decay is sampled as a function of time, t2,  The signal functions Si (t1 , t2, .PHI.i) is developed for systematically varied values of t1 and specially selected values of .PHI.i.  Linear combinations of the signal functions Si yield, after Fourier transformation a two dimensioanl spectrum of multiple quantum transitions limited by the choice of phase and linear combination.          In another embodiment, a magnetic gradient pulse is applied during the evolution period and resulting multiple quantum transitions yield spectral peaks of width dependent upon the order of such transitions. In particular, all spectral peaks may be removed from resulting spectra save only zero order transitions.

Abstract: VARIABLE SIZE, MULTI-SECTION ARTICLE FOR CONDITIONING FABRICS IN A CLOTHES DRYER                           ABSTRACT           A variable size article for conditioning of fabrics in a laundry dryer comprising a multi-section, sheet-like flexible sub-strate carrying one or more conditioning agents transferable to fabrics when tumbled therewith in a clothes dryer.  The dryer operator varies the size of the multi-section flexible substrate to match the amount of fabric conditioning agent to be used to the load size, or quantity of clothes, loaded in the dryer.     The fabric conditioning article may comprise synthetics such as polyesters and rayon, or natural materials such as cotton, wool felt, or any cellulosic or non-cellulosic material, and com-binations of any of these, in combination with fabric conditioning substance.  The substrate material is preferably in sheet form, and may be woven, non-woven, carded web, or formed as a continuous film.          Non-woven fibrous  materials may be water-laid, air-laid or other-wise formed into sheets.  The conditioning materials may be incor-porated during fabrication of the article, or may be subsequently combined with the substrate by immersion, padding, spraying, roller contact, brush contact or any convenient means.         Typical fabric conditioning agents include cationic fabric softeners, nonionic and anionic surfactants, perfumes, brighteners, crisping agents, sizing materials and combinations of these.  The preferred mode of use is in the clothes dryer, but the article may also be used in the washing machine, preferably in the rinse cycle.

Abstract: 46,446 SYMMETRICAL COMPONENT SEQUENCE FILTER                          ABSTRACT OF THE DISCLOSURE                            A symmetrical component sequence filter which provides a signal responsive to a predetermined sequence quantity of an electrical power system, while using only one phase shift other than 180 degrees. A single reactive element provides the phase shift. A single adjustable resistor calibrates the filter when the reactive element is non-precision.  Selecting a precision reactive element eliminates even the single adjustment.  The symmetrical component sequence filter enables both a positive and a negative sequence component to be simultaneously derived from common processing circuitry, requiring only one addi-tional reactive element.

Abstract: MICROPROCESSOR TONE SYNTHESIZER WITH      REDUCED QUANTIZATION ERROR            Abstract The accuracy of a required tone set, digitally synthesized by a microprocessor, is improved beyond the theoretical limit of the microprocessor circuitry by producing each tone at a frequency which is a sub-multiple of the desired frequency, then multiplying to provide the desired frequency.  With the addition of a multiplier such as a doubler, a better choice of oscillator frequency becomes possible which further increases the tone frequency accuracy.  The microprocessor can also reduced the start up time and the time between tones, eliminating delays in transmitting a series of coded tones.
