Abstract: A compact device projects Standard 8 and Super 8 film on a self contained screen. The films are continuous and are contained in individual film cartridges. Insertion of the film cartridge serves to adjust the viewer for the particular film contained therein. The adjustments include setting of mask size, mask position, image position on screen, stopping point of the film advance claw, adjustment of film advance stroke and lateral position of the film advance claw. The viewer will advance the film even when the film advance opening is damaged.

Abstract: In a pulse generating circuit, such as an implantable cardiac pacer having parallel connected batteries as its power supply, additional resistors are connected between the power supply and the pulse generating circuit of the pacer and form a part of the pulse generating circuit to indicate by a change in pulse rate when one or more cells of the batteries of the power supply fail prematurely.

Abstract: Apparatus is provided for sensing physiological potentials of a living body. There is provided a first band for at least partially encircling a part of the living body and having a first electrode mounted thereon. The first electrode is adapted for connection to an instrument for amplifying the physiological potentials of the living body. A second band is provided for at least partially encirling another part of the living body and has a second and a third electrode located thereon. The second and third electrodes each are adapted for connection to the instrument for amplifying the physiological potentials of the living body.

Abstract: A system for rapidly substituting one source of AC power for another. A solid-state gated electronic valve is coupled in circuit with a principal power source or "line" and the current through the valve is monitored. Line voltage is also monitored and a timing signal produced to keep the system in synchronism with the principal power source. When the source voltage decreases or changes abruptly, or if its phase drifts unacceptably, the difference detected between the source and a reference effects the termination of valve gating signals, and allows the application of synchronous enabling signals to a standby power source. If the solid-state valve is non-conducting the standby source starts immediately in synchronism with the previously-supplied load voltage. If current is flowing in the valve, however, a commutating signal is produced which overrides the synchronous standby enabling signal to energize the standby power source with the proper polarity to extinguish current through the valve. When the current decreases below the holding current value the standby source is caused to enter the synchronous mode.
