    Abstract: A learning device comprises a receptacle for holding an information bearing card. The information bearing cards include a problem and a coded answer. The receptacle of the learning device includes a decoding display window with a movable writing screen which may be moved to cover or uncover the decoding display window. The user can insert the information bearing cards into the receptacle, write down a response on the writing screen with the display window covered, and compare their response with the correct answer by moving the movable writing screen to reveal the decoded answer through the decoding display window.

    Abstract: A calendar display includes a flat support defining a plurality of scored lines of structural weakness. A plurality of stacked sheets bearing weekly and monthly time indicia are removably connected to a front surface of the support adjacent to a first, upper edge of the support. An adhesive strip is located adjacent to the first, upper edge on a back surface of the support. Manipulation of the support by bending the support in predetermined directions about the scored lines of structural weakness and contacting the adhesive strip with the back surface of the support adjacent to a second, lower edge of the support permits the support to be configured as a self-supporting stand for displaying the sheets on a horizontal surface. The support also can be severed along a predetermined one of the scored lines of structural weakness to provide a display of the sheets which can be attached to a vertical surface by means of the adhesive strip or by a magnet connected to the back surface of the support adjacent to the first, upper edge of the support.

    Abstract: Disclosed is a ball point ink pen, its ink and its eradicator. The ink is carried at one end of the pen and the eradicator portion is carried at the other. If an error is made, the pen can be reversed and the eradicator used to neutralize the ink. The ink also neutralizes the eradicator so that when one rewrites with the same ink, any remaining eradicator on the paper is neutralized and the original ink acts as fresh ink.

    Abstract: A secure contest card which is not susceptible to compromise by both simple and sophisticated techniques comprises printed indicia disposed on the upper surface of card stock material, a patterned intermediate layer disposed over the printed indicia and an opaque removable mask disposed over the intermediate layer and over the printed indicia. In a second embodiment of the invention a patterned background layer is disposed between the card stock and the printed indicia and the patterned intermediate layer is eliminated. In a third and preferred embodiment, the patterned background layer and the patterned intermediate layer are both employed. It has been found that the pattern in the background and intermediate layers creates an irregular relationship with the indicia and defeats certain new techniques for compromise of apparently secure contest cards.

    Abstract: A device for the application and recording of written tests such as word or idea association; question and answer; evocative or suggestive tests; aptitude etc. Pre-printed tests on paper rolls are inserted into the machine and the tests sequentially appear in a slot or window which remains open for a predetermined length of time during which an answer may be written on the test paper. A timer control adjusts the timing for the slot opening and closing. A control button allows an examinee to move on to the next question should he be able to reply in less than the alloted time and the length of time taken to reply is automatically recorded on the test paper. An attachment is available for ink blot or other visual tests.
