A CRT shadow mask 9 is made by clamping the outer periphery of a blank, stretch or draw-forming the main spherical surface 9a of the mask, releasing the clamping and wipe-forming the skirt 9c of the mask, and finally press-forming a peripheral spherical border 9e inward of the skirt and having a sharper angle of inclination. The border prevents the spring-back of the high yield strength mask material and the attendant formation of creases and dimples in the mask surface. The die press for implementing the process features an inner pad 32 surrounded by an outer pad 31, both defining spherical surfaces configured to mate with those of a punch 1 for individually forming the main surface and border of the mask. The components are arranged such that a single downward stroke of the press successively implements all of the forming steps.
The present invention provides an improved color picture tube having a viewing screen and a shadow mask mounted adjacent to the screen. The mask has an apertured contoured portion and a peripheral skirt. The improvement comprises the skirt having a reverse bend therein, wherein a first portion of the skirt that connects with the apertured contoured portion extends away from the screen and a second portion of the skirt more remote from the apertured contoured portion extends towards the screen.
The present invention provides an improved method of forming a shadow mask for a color picture tube from a flat apertured mask. The mask has an central apertured portion, a solid border portion and a skirt portion. The improved method comprises several steps. First, a flat apertured mask is placed beneath an upper punch. Next, the periphery of the mask at the skirt portion is clamped. The punch then is pressed against the mask to contour the mask in its central apertured and solid border portions. Thereafter, the periphery of the mask at the skirt portion is unclamped, and the solid border portion of the mask is pressed between a bead die and the punch to form a peripheral bead in the solid border portion of the mask. Finally, the skirt portion is swept back to substantially parallel a central longitudinal axis of the formed mask, while the border portion is held between the bead die and the punch.
A multi-compartment pill container constructed to hold a week's worth of medication for a user. The container has a housing having a top surface, a number of removable compartments held within the rectangular openings in the top surface of the housing, and a lid attached to the housing and extending over the compartments. Each compartment is divided into chambers by separation walls. Each chamber has a chamber cover on which indicia is printed. The indicia includes abbreviations for the days of the week for each of the compartments, as well as times of the day for each of the chambers. At the correct time, the user ingests the medication from the appropriate chamber. The container also includes a telescopic drinking cup to aid in the taking of medication and a timer to notify the user to take the medication. Each compartment may be completely removed from the housing to allow the user to carry the compartment separate from the entire container.
A method for forming a constant geometry and non-turbulent stream inducing pouring spout in the rim portion of an annular side-walled vessel. The method comprises the steps of: a) positioning the vessel within a clamp possessing a groove whose centerline forms a 90.degree. angle with the annular side wall of the vessel when the clamp is in place; b) placing inside the vessel a center plug possessing a radially extending groove whose centerline forms a 90.degree. angle with the annular side wall when the center plug is in place; c) aligning the centerlines of the grooves of the clamp and the center plug to form a straight line travel path; d) placing a pour spout former in the center plug portion's groove and causing the former to travel along the travel path and into contact with the rim portion of the vessel; and, e) further causing the former to travel along the travel path to yieldably deform the rim portion of the annular wall into the desired shape pouring spout. The actual deformation of the rim takes place in three stages. The first stage and third stages involve deforming the rim portion by the former in an outward and upward direction and an outward and downward direction, respectively, while the second stage involves deforming the rim portion in only an outward direction.
