The Family

For the family embarrassment and annoyance brought by the replacement of slippers when someone pays a visit, a cutting paper tape machine for sole coating was designed. Based on the detailed calculation and preliminary drafted general design scheme, the electric motor was chosen, the transmission ratio was distributed reasonably, the structural style and related parameters of worm gear were designed, and the stress strength was checked. Based on these, the three-dimensional model was established, through simply simulation, the scheme was verified and improved, and the parametric design was realized. Thus, one kind of convenient and practical cutting paper tape machine for sole coating is provided for families and high-grade places, which is greatly convenient to visitors.

Reduction of magnetic anomalies to the magnetic pole and magnetic equator can be regarded as a linear transformation. The Hermitian transfer function characteristics of these transformations are discussed and improved using the Gaussian band‐pass window. This procedure is of use in one‐ and two‐dimensional cases. The application of the Gaussian band‐pass window eliminates the finite discontinuity of the transfer function of reductions at zero frequency in all cases. The frequency band passed by the Gaussian window can be controlled by its parameters. Reduction to the equator can be used at low magnetic latitudes where reduction of two‐dimensional anomalies to the pole has some instabilities caused by the infinite discontinuities of its transfer function. The windowed reductions are illustrated by their application to magnetic anomalies produced by two‐dimensional and three‐dimensional prisms.

Resonance Relation

The paper presents a summary of the results obtained by C. J. Cohen and E. C. Hubbard, who established by numerical integration that a resonance relation exists between the orbits of Neptune and Pluto. The problem may be explored further by approximating the motion of Pluto by that of a particle with negligible mass in the three-dimensional (circular) restricted problem. The mass of Pluto and the eccentricity of Neptune's orbit are ignored in this approximation. Significant features of the problem appear to be the presence of two critical arguments and the possibility that the orbit may be related to a periodic orbit of the third kind.
