Abstract: Abstract of the Disclosure A battery charger employs an integrator and current switch in combination with a control circuit.  The control circuit receives a synchronizing signal at the start of each charging cycle as determined by a cyclical supply or pulse generator as well as information about the state of the integrator which is compared with the predetermined average current.  The aforementioned information determines the required control signals for the integrator and current switch so as to maintain the value of the charging current substantially constant throughout the charging time.  The charger also includes a current sensor for sensing the current flow through the battery being charged and which supplies the integrator with the value of sensed current.

Abstract: ABSTRACT OF THE DISCLOSURE           A method for preventing the dropping of individual bricks from a sprung arch roof employed in a continuous tank-type glass melting furnace, the dropping of the bricks normally occur-ring during heat-up of the furnace.  The slightly tapered bricks employed in constructing the roof are oriented with their long axis in the vertical direction and, as heating occurs and the structure differentially expands and the bricks dry out, some be-come sufficiently loose to drop from the roof into the tank of the furnace.  In visually observing the interior surface of the roof during heat-up, it can be seen which bricks are settling and likely to drop therefrom.  These bricks are pulled up through the roof from above by a suction cup and mortar is placed around the bricks.  The bricks are then dropped back into place with the mortar holding the bricks until they become wedged firmly in place as the temperature of the roof increases.

Abstract: 2.   Abstract of the Disclosure:    Improvements in a streophotographic process for producing works of sculpture by arranging a number of cameras and a number of projectors, each fitted with a screen having a number of parallel stripes, in a circle around an object so as to face the latter, taking pictures of the object simultaneously with the cameras while the striped screens are being projected thereon by the pro-jectors, replacing the projectors and cameras by an increased number of projectors arranged in similar posi-tions to face instead a mass of material to be modeled which is placed at the center, projecting the pictures as well as the screens fitted in the projectors on the mass of material, and then modeling the material until the stripes of the same sources on the screens and pictures projected are in coincidence on the material surface.  The improved process is characterized in that each pair of adjacent projectors are fitted with pictures, one for each, or a picture for one and a screen for the other to match, when projected, on the material surface, either picture or screen being positive and the other being negative, only such matchable projectors are lighted to project stripes s"' which combine the stripes s' and s" of the positives and negatives in coincidence and also fringelike pro-jections of unusual brightness and darkness appearing on both sides of the stripes s"' as indications of unmatched stripes, and then the material is modeled by eliminating the portions represented by the projections until an original model of uniform lightness is reached.

Abstract: DOUBLE VERNIER TIME INTERVAL MEASUREMENT USING TRIGGERED PHASE-LOCKED OSCILLATORS               Abstract of the Disclosure Measurement of a time interval between a start and a stop event is made by activating a start oscillator in response to the start event and activating a stop oscillator in response to the stop event.  The number of cycles of each respective oscillator signal which occur between the activation of each oscillator and the coincidence of the respective oscillator signal with that of an independent time base is determined.  The number of cycles of the time base signal between the coincident points of it and the start and stop oscillator signal is also determined.  These numbers, which are always integers, are used along with the values for the time base period and the difference in frequency between the time base oscillator and the start and stop oscillators to calculate the time interval.  Resolution of the measurement is dependent on the frequency difference bwtween the time base signal and the start and stop oscillator signals.  Two triggered-phase oscillators, which are phase-locked to the reference oscillator, are used to supply the start and stop frequencies.  The start trigger and stop signals are used for phase shifting, i.e., restarting of the oscillators rather than starting the  oscillators.  This allows for pre-trigger frequency control, and essentially eliminates post trigger frequency drift which usually occurs when an oscillator is first started.  The coincidence signals are provided by the phase cross-over between the phase locked oscillator and the reference by a digital mixer.
