Disclosed herein is an improved instantaneous photography camera for use in the manufacture of photographic identification cards. The camera is of the type in which one or more masks are provided within the camera box of the camera to allow the sequential exposure of a portion of photosensitive film to an image containing credit information and an image of the subject of the credit identification to form a photographic identification card.

An instantaneous torque determining apparatus for obtaining the instantaneous torque value continuously of a shaft rotating at a high speed. The apparatus includes a pair of spaced gears mounted on the shaft, a torque detector having a pickup for each gear, a set of voltage comparators, a gate control circuit, an AND circuit, and a clock pulse generator. Further, the apparatus also includes a delay circuit for receiving pulses from a voltage comparator, a subtraction counter which receives a del...

An improved instantaneous floating point amplifier is provided having a plurality of cascaded amplifier stages, wherein the gain of a given stage of the amplifier is the square of the gain of the immediately succeeding stage of the amplifier. The number of amplifier stages which are required to implement the amplifier is minimized, and the control logic which is required to decide if a given stage is needed to amplify the input signal to a level within preselected limits is simplified. The ampli...

A heater for the rapid heating of water includes a main body having plural vertical upwardly opening chambers, combined with a molded cover plate that can be removably installed over the upper part of the main body. A plurality of combination heating and chamber partition assemblies extend downwardly from the bottom surface of the installed cover plate and one each of the assemblies resides in a main body chamber, each assembly including a generally flat and vertically elongated partition member...

A method and apparatus for processing the log video output of a receiver that can measure multiple time overlapped pulses on a nearly instantaneous basis. The receiver measures frequency, pulse modulation, time of arrival, amplitude, pulse width and phase difference when simultaneous pulses are present. To detect pulse parameters a given voltage threshold must be exceeded and M out of the last N data samples must fall within a given voltage window that is above the threshold voltage. Pulse detec...

A day disk cooperates with a storage of mechanical energy via a seven-position Maltese mechanism. A Maltese cross of said mechanism is rigidly coupled to and coaxial with the day disk. A transfer pin of the Maltese cross is set on an intermediate gear of the storage. A driven disk includes a projection for the transfer of a toothed date ring. The locking surfaces of the Maltese cross lock on the driven disk. Provision is made of a free unloaded lever with one arm locking in position the date rin...

Disclosed is a gas instantaneous water heater for use in boats or recreational vehicles comprising a housing divided into a large upper portion and a small lower portion. A gas valve and electric filament lighter are controlled by an electronic module which opens the gas valve and ignites the gas in response to a signal from a sensor capable of sensing water flow or a pressure drop. The heater employs a photoelectric flame sensor and a thermal override switch to shut off the gas in the event the...

Instantaneous intermittent feeding mechanism having a continuously rotating driving member and a driven member coaxial therewith. A spring resiliently couples the driven member with the driving member so that, when a relative rotation is established between the driving member and the driven member by temporarily holding the latter stationarily while the former is rotating, a rotational driving force is given to the driven member by the spring so as to instantaneously rotate the same. The driven ...

An apparatus for simultaneously and instantaneously determining direction and frequency of an unknown transmitted signal which is received by an omnidirectional antenna and mixed with a local oscillator, the output of which is again mixed in a plurality of mixers each fed by one of a plurality of directional antennas in a circular configuration. The output of the plurality of mixers, being the intermediate frequency, is fed into a vector resolver which controls deflection plates of a CRT and ind...
