Abstract
Abstract A language teaching device which includes an open-ended holder in which can be received a card having intelligence in a first foreign language provided on the opposite faces of the card. The intelligence is arranged on the card in a column of successive linear entries extending longitudinally of the card and corresponding intelligence in the language of the user is provided in like manner on portions of the sides of the holder, the holder being of a transparent material which is masked in respect of the portions thereof carrying intelligence so that the card may be viewed through the unmasked portions. The card and holder further are provided with cooperating indicia means for assuring that the corresponding side of the card appears through the unmasked portion of the holder and for aligning the intelligence on the card and that on the holder registrably thereby associating any given entry in the language of the card with its corresponding equivalent in the language of the holder.

Claim 4
Dependent Claim
102 words
The language teaching device of claim 2 wherein the area on one face surface of said card having intelligence thereon is disposed at one side of said medial longitudinal axis, the area on the other face surface of said card having intelligence thereon being disposed at the other side of said medial axis, the areal portion of one of said holder sides masked by said masking means being disposed at one side of the medial longitudinal axis of said holder, the areal portion of the other of said holder sides being disposed at the other side of said holder medial longitudinal axis.
Claim 5
Dependent Claim
46 words
The language teaching device of claim 3 wherein said card has transverse margins at opposite ends thereof, the intelligence on the said one area of each of said face surfaces of said card being arranged to be upright readable relative to one of said transverse margins.
Claim 6
Dependent Claim
128 words
The language teaching device of claim 4 wherein additional intelligence is provided on the other areas of each of said face surfaces of the card, said additional intelligence being arranged in a column of successive linear entries extending longitudinally of the respective other face areas and such to be upright readable relative to the other of said transverse margins, the additional intelligence on said other face areas being registrably alignable with the intelligence on said holder when said card is received in said holder in a disposition in which it has been rotated in a plane 180* in respect of the disposition of said card in said holder when the intelligence on said one area of each face surface is registrably aligned with the intelligence on said holder.
Claim 7
Dependent Claim
