The Universal Book Holder permits a person to read from supine, sideways facing, sideways-upward facing as well as from the usual forward and downward facing postures. The book holder accepts hard cover books, paperbacks, magazines and newspapers. Insertion and removal of books is done by the user without changing his/her reading position and does not require any manual dexterity whatever.

Universal book holder

A book holding structure is provided having means to position a book in two positions, one for turning the pages of the book the other for reading from a supine position, means to flatten and to illuminate it and to convert it into a conventional easel.

Inverted book holder

A book holding structure is provided having means to position the book in two positions, one for turning the pages of the book and the other for reading.

An extended life incandescent lamp which employs thermal, voltage, or radiation activated differential switching to substitute a series-connected reserve filament for an inoperative primary filament without increasing the normal in-rush current.

A compressed data display system. There is disclosed a system for recording over extended periods of time EKG and other vital signs of a patient and for automatically displaying the waveforms in a compressed and readily interpretable manner. The EKG waveform is recorded on looped paper supported by and/or wrapped around rotatable drum or drums which may have cylindrical shape. The EKG is recorded in helical or spiral fashion by simultaneously rotating the drum and transversely moving a galvanometer pen in the direction of the axis of rotation of the drum or cylinder. After the paper is removed, if it is a continuous or closed loop, it can be slit and opened into a single sheet. The recorded EKG waveforms are thus displayed compressed in a line-over-line manner and provide the physician with a clear picture of the patient's heart activity for extended periods of time.
