Abstract: A spin tuned magnetron has a spinner the axially facing end of which lies in an inclined plane and an anode vane ring having an annular flange the end face of which lies in an inclined plane so that the amount of overlap of the flange and spinner varies as the spinner rotates. (In the FIG. 4A the spinner and the ring are shown spaced far apart; in practice they are spaced so that the planes coincide when parallel).

Abstract: A lithographic printing process wherein an illuminated image on a document is scanned in a series of parallel sweeps with a photocell, applying an electric wave signal to a magnetic recording head with the amplitude of said signal determined by the output of the photocell and a function of the optical density of the image being scanned. The magnetic head has a width of from about 0.5 mils to about 5 mils and traverses a magnetic recording medium in a series of aligned parallel paths analogous to those scanned by the photocell to form a latent magnetic image in the magnetic recording medium, which image is a replica of the image being scanned. The horizontal spatial frequency is from about 200 to 1000 cycles/inch. The thus formed latent magnetic image is decorated with an oleophilic magnetic toner. The oleophilic magnetic image is transferred under pressure to a smooth heated lithographic substrate. If necessary, the toner is further heated to effect complete coalescence thereof.

Abstract: An improved locking mechanism is provided with a fixed outer cylinder and at least two side-by-side rows of resiliently urged pins disposed in a staggered relation therein. A face plate contains a nonrotatable key slot in angular disorientation to the pins and a key is provided with a plurality of biased grooves forming inclined planes to depress the pins as the key, imposed in an inner cylinder, are rotated together through the plane of the pins.

Abstract: The invention provides an NMR machine capable of a volume scan. Initial data is provided for a plurality of planes in the body, instead of a plurality of lines as previously, and this is repeated at different positions rotated about an axis parallel to the plane. Convolution processing thus yields data for a matrix of lines parallel to that axis. Further rotation about the z-axis and repetition of the previous analysis at each stage yields data for such matrices of lines at different angles to the z-axis and further convolution processing provides data for a three-dimensional matrix of elements in the body. The last mentioned processing may be done in individual ones of parallel planes.

The ratio of average particle diameter of the carrier particles to average particle diameter of the particulate material is greater than 2 and the weight ratio of particulate material to carrier particles is less than 1. A durable matte finish is obtained that is nonblocking, is capable of being written on, and is noncracking over extended storage periods.
