摘要： A teaching system comprising a console furnished with a tape recorder and a graphic recorder, each adapted to be controlled from recorded signals produced by the tape recorder. Control apparatus is provided for enabling the user to address recorded lecture material, or recorded answer material, at will, under the guidance of a lecture map. The student can listen to a recorded lecture without interruption, or can interrupt it at will in response to suggestions on the lecture map of questions that may be raised by the lecture. When the lecture is interrupted, the recorded answer material may be addressed to produce a recorded answer to the question selected from the map. At appropriate intervals during the lecture or answer recordings, the graphic recorder may be utilized to present visual material supplementing the recorded audio material.

摘要： A thin battery of the Le Clanche type incorporating a multiplicity of electrically conductive layers arranged to cooperate in conjunction with electrochemical material to form a multicell battery. Continuous frametype sheet seals are thermally bonded to the periphery of each of the conductive layers to provide an insulative sealing arrangement. The outer peripheries of these frames also are heat sealed to provide a rigid, secure border seal for the battery assembly. Sheet separators are positioned intermediate superpositioned ones of the electrically conductive layers and extend beyond openings within the frametype seals.

摘要： Photographic apparatus and a remote control system therefor which functions to carry out a series of operational events in response to the brief manual depression of a remote start switch. The control system incorporates an electronic latch which is activated only after select initial ones of these operational events are carried out. Additionally, the control system incorporates a feature insuring the successful commencement of a photographic cycle by delaying the deactuation of the start switch after a brief depression thereof.

摘要： This invention is an improved landscape lens for a simple photographic camera. The improvement is achieved by placing a vignetting stop midway between the lens element and its regular aperture stop. It reduces the amount of blur otherwise found in the image at points removed from the center of the field. An aspheric refracting surface on the lens element further improves the image.
