Abstract: ABSTRACT A power controller arrangement employs a digital processor to mon-itor and control plural loads, e.g.,   to monitor and maintain at prescribed levels the temperatures of plural missiles. During each load data processing cycle of operation, the processor presets a down-counter which governs load (e.g., missile heater) energizing power by duty factor modulation.  The value preset into the counter is dependent upon any measured temperature error, and the then obtaining load power level.  In accordance with one aspect of the present invention, the modulation governing counter is periodically decri-mented to progressively reduce power delivered to a load absent sufficiently frequent processor updating of the load-associated regulating circuitry. This provides fail-safe load passivation upon processor failure or overload.

Abstract: ABSTRACT       An adjusting device for an electronic digital display which has a first pulse generator for producing counting pulses is described.  The ad-justing device includes a 'second' pulse generator which can be adjusted over a range of frequencies and a 'third' pulse generator which operates at a higher frequency.  A discriminator determines whether the pulse frequency of the second pulse generator exceeds a predetermined value and if it does, the third pulse generator is switched in.  This has the advantage that, of the display of a chronometer has to be adjusted by several hours, this can be done much more quickly.

Abstract: AN OPTICAL READER FOR INFORMATION DISCS EQUIPPED WITH MEANS       FOR AUTOMATIC ACCESS TO THE INFORMATION            ABSTRACT OF THE DISCLOSURE:         The optical reader, for information discs of which the items of information are locatable by addresses previously recorded on each of the grooves forming the track, comprises a device for counting the number of grooves traversed during search phases which simultaneously uses the envelope of the reading signal and the signal representing the radial error in the position of the head relative to the nearest track, for algebraically counting the number of tracks traversed.  After comparison with the number of grooves to be traversed, the counting device controls the deceleration of the radial advance when the spot is at a predetermined distance from the groove to be reached and also its total stoppage and the closure of the radial servocontrol loop when the groove is reached.

Abstract: METHOD OF HIGH SENSITIVITY IMAGING     AND IMAGING FILM THEREFOR                        Abstract of Disclosure A dry process high sensitivity imaging film includes a solid, high optical density and substantially opaque film of dispersion imaging material deposited on a substrate.  The film of dispersion imaging material comprises a plurality of separate layers of different and substantially mutually insoluble components having relatively high melting points and relatively low melting point eutectics, and interfaces between said layers having re-latively low melting points.  Energy is applied to the film of dispersion imaging material, in an amount above a certain critical value sufficient to increase the absorbed energy in the film material above a certain critical temperature value related to the relatively low melting points of the interfaces, to substan-tially melt the low melting point interfaces and incorporate the different and substantially mutually insoluble components of the separate layers into the substantially molten interfaces and, hence, to change the film to a substantially fluid state in which the surface tension of the film material acts to cause the sub-stantially opaque film, where subject to said energy, to disperse and change to a discontinuous film comprising openings and deformed material which are frozen in place following the application of energy and through which openings light can pass for decreasing the optical density thereat.  Also, means may be associated with the film of dispersion imaging material for retarding the disper-sion and change to the discontinuous film, caused by the surface tension, and for controlling the amount of such dispersion and change in accordance with the intensity of the applied energy above said certain critical value to provide continuous tone imaging of the dry process imaging film.
