Abstract: Disclosed is an improved printer and carriage drive mechanism. The carriage motor is mounted at a first side of the printer chassis, and an idler pulley is mounted at a second side of the chassis. The carriage also has a pair of idler pulleys. A single flat smooth belt is attached to the first side of the chassis. From there, it passes over to and around one of the idler pulleys on the carriage, back to and around the motor pulley, across the print zone and around the idler pulley on the second side of the chassis, back to and around the other carriage idler pulley, and then back to the second side of the chassis, where it is attached. The motor is movably attached to the chassis and is tensioned by a spring. This mechanism provides for substantial mechanical advantage over common simple carriage drive mechanisms. A smaller, less expensive motor and a quieter flat smooth belt can be used. The motor is allowed to run at more optimal speeds and expensive ball bearings can be avoided in the motor and pulleys.

Abstract: A printing head structure of calculator, including a belt type printing head the outer periphery of which is disposed with at least one group of fine characters and at least one group of coarse characters. The fine characters have the same symbols and numerals as the coarse ones, while having different thicknesses and letterforms. By means of a printing control program of the calculator, the printing head is able to print out a positive or negative result respectively by fine characters or coarse characters so as to apparently visually distinguish the positive result from the negative one and thus achieve a reliably reminding effect.

Abstract: An anti-barking and anti-biting muzzle for dogs includes a muzzle portion formed from a pair of generally trapezoidal flaps of elastic material sewn together along the converging edges thereof, with the flaps being further divided by a seam along the longitudinal centerline thereof to create four panel members of the elastic material. An elongated strap is connected at its ends to opposed seams of the muzzle portion. The muzzle can be slid onto the snout of a dog and the strap fitted over the dog's head behind its ears. The muzzle portion has a snug fit on the snout but the elasticity of the material allows the dog to open its jaws slightly for panting. If the dog tries to open its jaws wider to bark or bite the four elastic panel members apply a force to the jaws to prevent them from opening wide. The muzzle is not uncomfortable and it acts as a training aid since the animal associates the wearing of the muzzle as a form of punishment for barking or biting.

Abstract: A process for a production basis relief decorating of ceramic articles. In place of conventional, manual application of relief features, the process provides for a special technique for screen printing of relief features onto the surface of a transfer decal sheet, typically a decal sheet that has previously been printed with a conventional, two-dimensional primary design. The new process includes a screen printing stencil of unusual thickness, at least 0.015" and up to as much as 0.125", characterized by having unrestricted non-convergent through openings. Ceramic inks are formulated to heavy viscosity, having a characteristic comparable to peanut butter, with a viscosity in excess of one million cps. The ink is flow resistant in character, and is forced through the stencil openings by a slow-moving squeegee. The squeegee action is such as to provide increased dwell time of the ink with the surface of the transfer decal paper, before lifting of the stencil.
