Abstract: METHOD OF OPTICALLY PRODUCING A REPRODUCIBLE    RECORDING OF VIDEO OR OTHER SIGNALS                ABSTRACT OF THE DISCLOSURE           In optically producing a reproducible recording of video or other signals, the intensity of at least one laser light beam is modulated by the signals to be recorded while such light beam scans a substantially flat surface on a photo-sensitive recording medium which is photo-reacted to a depth varying substantially linearly in correspondence with the intensity of the light impinging thereon over a predetermined range of light intensities, and the intensity of the light beam and the degree of modulation thereof by the signals are selected to maintain the maximum and minimum intensities of the modulated light beam within such predetermined range so as to form simultaneously on the record medium a tracking path portion and a recorded signal portion which is unified with the latter.  The photo-sensitive record medium is desir-ably constituted by a positive photo-resist so that the track-ing path portion is obtained in the form of a groove having the recorded signal portion defined by irregularities at the bottom of such groove.  The positive photo-resist or other photo-sensitive material may be conveniently applied as a layer on a base plate or disc which is rotated while the light beam and disc are moved relative to each other in a radial direction of the disc so that the groove or other tracking path portion forms a spiral.

Abstract: Abstract of the Disclosure The cutting edge of a scalpel blade is heated to an elevated preselected constant operating temperature for cutting tissue with simultaneous hemostasis by radiant heating of the blade in the region along the cutting edge.          Radiant energy is contained within the blade by a reflec-tive coating over the transparent or translucent blade material.  Heating along the cutting edge is provided by the disposition of a radiation-absorptive material beneath the reflective coating in the region along the cutting edge.  Selective heating of regions of the cutting edge that are locally cooled by contact with tissues during surgical cutting is provided for by fabricating the radia-tion-absorptive element of the blade of a thermochromic material that exhibits a substantial increase in absorp-tion coefficient for a temperature decrement within the operating temperature range.

Abstract: PHOTOELECTROPHORETIC CONCURRENT PROCESS CYCLING   APPARATUS                ABSTRACT OF THE DISCLOSURE           A photoelectrophoretic imaging machine for producing, in a preferred embodiment, full color copies from opaque originals or, alternatively, copies from transparencies.         In a preferred embodiment, the formation of photoelectro-phoretic images occurs between two thin injecting and blocking webs at least one of which is partially transparent and the image formed is transferred to a paper web.  The injecting and blocking webs may be disposable, thus, cleaning systems are not required.  The injecting web is provided with a conductive surface and is driven in a path to the inking station where a layer of photoelectrophoretic ink is applied to the conductive web surface.  The inked injecting web is driven in a path passing a deposition scorotron at the precharge station and into contact with the blocking web to form the ink-web sandwich at the imaging roller in the imaging zone.      The conductive surface of the injecting web is grounded and a high voltage is applied to the imaging roller subjecting the sandwich to a high electric field at the same time as the scanning optical image is focused on the nip or interface between the injecting and blocking webs, and development takes place.  The photoelectrophoretic image is carried by the injecting web to the transfer zone, into contact with the paper web at the transfer roller where the image is trans-ferred to the paper web giving the final copy.  In one preferred embodiment, machine components and subsystems are arranged and operated to accomplish the process steps of inking, imaging and transfer concurrently.
