A magnetic encoder, which comprises a stainless steel sheet; and an under coat adhesive containing epoxy resin and organopolysiloxane, a top coat adhesive containing phenol resin, or phenol resin and epoxy resin, and a rubber magnet, as successively laid one upon another on the stainless steel sheet, has distinguished water resistance and saline water resistance, and thus can be effectively used particularly as a magnetic encoder in wheel speed sensors.

A multiple-color tampon printing machine with a tampon carrier member is rotatable in a step-by-step movement about a first axis. A stereotype plate carrier member is rotatably mounted about a second axis which extends parallel to the first axis. The stereotype plate carrier member carries out a step-by-step rotating movement synchronously with the tampon carrier member. The tampon carrier member additionally carries out an up-and-down movement at predetermined fixed positions of rotation. A surface of a stereotype plate, a printing material holding device, and a tampon cleaning device are arranged in a common plane and in a circle around the tampon carrier member, such that, when the printing material is held stationary, a first tampon picks up a printing image from the respective stereotype plate surface, a second tampon preceding the first tampon prints the printing image onto the printing material, and a third tampon following the first tampon is cleaned by the tampon cleaning device. This procedure is carried out cyclically until all tampons have transferred the respective printing image to the printing material. A cyclically operating stereotype plate inking device applies printing ink on each stereotype plate prior to the transfer of the printing image by the respective tampon.

A mirror formed from a generally sheet-like unbreakable body having opposite surfaces, one of the surfaces being a reflective surface, a first removable transparent protective sheet covering and protecting the reflective surface, a magnetic adhesively bonded to a second of the surfaces whereby the mirror can be removably attached to magnetically attractive support surfaces, and a strip of double-faced pressure-sensitive tape adhered to the magnetic but removable therefrom whereby the mirror can be adhesively secured to a non-magnetically attractive support surface.

A pad printing apparatus is provided with a sealed ink cup for the printing of long images having a length greater than the diameter of the ink cup. The ink cup is caused to move lengthwise of the image and the movement of the image transfer pad is in a direction perpendicular to the lengthwise direction of the image.

Disclosed is a drafting implement to aid a draftsman in drawing curves. The implement may be called a Curve Stripe. The implement includes an elongated soft metal core having a plurality of openings formed therein at intervals along the core. Magnetic beads are disposed in the openings and have at least one flat surface which is disposed normal to the elongated axis of the core and projects outwardly therefrom. A rectangular strip element is disposed adjacent to the core and arranged to inhibit motion thereof in a direction normal to the at least one surface of the beads. A pliable plastic jacket is provided to surround the core, the strip element and the beads, the jacket having openings therein matching the at least one surface of the beads.
