An apparatus for use in teaching comprises a carrier (10,20) of information that is to form the subject-matter of a lesson; a keyboard (12) having its keys marked with symbols which include those related to the said information; a visual display unit (14) having a screen (15); a computer (13) which is programmed in relation to said information to check the accuracy of a student's transcription of at least part of the information by indicating on the screen and/or audibly, the performance of the ...

A process of teaching the use of keyboards thereby enabling keyboard operators to produce large quantities of printed material in a much shorter time at higher accuracy. The process instructs keyboard students to associate printed material with four specific finger movements rather than keyboard memorization, thereby securing proficiency for keyboard students in as little as four hours rather than the usual six to thirty six weeks.

A toy or model aircraft with motions that can reproduce the operational status and flight attitude of the corresponding real aircraft. Model aircraft include a vertical motion device for enabling the aircraft body to ascend or descend in order to reproduce changes in position from a state in which the aircraft is set at a lower position so as to copy the attitude of the corresponding real aircraft during a halt on the ground to a state in which the aircraft is set at a higher position so as to c...

A structure for selectively displaying markers, or crayons, such selectivity being controlled by a keyboard whereby a user, on depressing an activator, may cause the selected marker to be elevated.

Disclosed is a system and method for measuring the emotional response of a subject to a chosen focus in order to reliably produce objective data representing that emotional response. The subject is put in contact with the chosen focus, and the emotional response of that subject to the chosen focus is determined in order to provide initial response emotions and the intensities of these emotions. The intensity of these same emotions without attention directed to the chosen focus is also evaluated ...

A teaching device, for use in a classroom, comprising a hand-held size calculator adapted to normally include a display for showing the numerical output of the calculator, and adapted to include a face plate having a plurality of keys which are arranged in a particular pattern and which bear indicia indicating the calculator function of the keys. The calculator does include a circuit for producing a signal in response to depression of the face plate keys of the hand-held size calculator. The tea...

Method of teaching keyboarding by providing a first simulated keyboard which is substantially the same size as a standard keyboard and which has means for dividing the keys into appropriate standard finger grouping columns and providing a second simulated keyboard which has means for visually dividing the keys into the same finger grouping columns as the first simulated keyboard. The invention also consists of first and second simulated keyboards for carrying out the above method.

To permit easy insertion and removal of a compact fluorescent lamp (2) in and from a socket, the socket is formed with a body (3) having an engagement surface wall (5) from which a shelf (4) projects bounded by side walls (22, 23) to define a base reception cavity (25). The engagement wall (5) is formed with slits (11) to permit terminal pins (13) from the lamp to pass therethrough, for engagement with electrical terminal contacts (T). The lamp is held in position by a resilient catch or latch o...

An improved method of inserting a coin return into an opening in a telephone paystation enclosure including the steps of inserting the housing of the coin return into an opening until a pivot area of the housing is aligned with and placed over a lower part of the opening; then pivoting the housing around the pivot area into the interior of the enclosure until a portion of an outer lip of the housing contacts a portion of the exterior surface of the enclosure and an upper slotted opening formed i...

A method of playing a game that includes the steps of providing a plurality of categories, selecting a category from the plurality of categories and communicating the categories to one or more teams of two or more players. Other steps include two or more of the players of one of more of the teams recording one or more responses to the category and ranking the one or more responses in an order, comparing the ranked responses between two or more of the players on the one or more teams, and determi...
