    Abstract: Apparatus in which the photographic images on a strip roll of silver halide film are duplicated upon a strip roll of electrophotographic film. The apparatus feeds the strips of the two rolls into contact with one another, emulsion side of the photographic film against the coating side of the electrophotographic film. At the projection station there is a projected light beam passing through the contacting films. A charging station is provided for charging the electrophotographic film just before it contacts the photographic film and a toning station and a fixing station respectively are located to act upon the electrophotographic film after exposure.Alternatively, the toned image may be transferred to a strip of clear base film from the coated surface of the electrophotographic film followed by fixing of the transferred image. The electrophotographic film then is reused while the clear base film becomes the duplicate of the original.The method involves the use of an electrophotographic film which will not lose charge by virtue of contact or by static electricity because of the separation of the films after contact. The electrophotographic film is coated with a very thin layer of insulating hydrocarbon before the contact occurs to prevent static discharge when the films separate and for other reasons.Background density of the original film is measured by photometric means and compared with preset density standards or used to adjust the sensitivity of the electrophotographic film through charging to provide optimum duplicated quality.

    Abstract: A system for impressing images on electrophotographic film provides apparatus for charging each film frame rapidly to a peak voltage determined by the prevailing light conditions of the image to be produced or recorded. After charging, means are provided for immediately exposing the frame to an image. In the preferred apparatus, means are provided for adjusting the time of exposure to a fixed period which is predetermined. Means are provided for applying toner to the exposed frame immediately after exposure in the presence of a bias field which propels the toner particles toward the film. Thereafter excess toner is removed from the film or leaves the frame and the remaining toner is fused to the surface of the film to form a permanent visible image on the film frame. An alternate form of the invention provides means for transferring the toned image to an acceptor member where it is fixed.The apparatus includes structure which enables the processes above described to be carried out along a line or in a rotary arrangement. Electronic and electrical circuitry are provided for accomplishing the various functions in proper sequence and timing.The apparatus is arranged to carry out the processes at points on the dark decay portion of the characteristic discharge curve for the particular film so that the resultant image has high resolution, optimum contrast and a substantially continuous gray scale. The quality is as good as if not better than photographic quality. The sensitivity of the film is controlled by the level to which it is charged and circuitry provided enables this to be automatically accomplished. The level in turn is chosen on the basis of the average light of the image or scene to be recorded and means are provided to accomplish this automatically or manually.

    Abstract: An electrophotographic film member is exposed to an image source, such as a cathode ray tube display unit, and the latent image toned to form a temporary visible image on said film member at a first station. The film member carrying the temporary visible image is stepwise translated to a projection station where it is projected in an enlarged display upon a suitable receptor surface. Thereafter, the film member is stepwise translated to an erase station where the toner is removed and the film member made ready for reuse to receive another image. The first station includes suitable structure for charging the film member, a selectively operable blind or shutter for exposing the charged film member to the image source and an applicator for applying suitable toner from a toner source to the exposed film member. The toner particles adhere tenaceously but removably to the exposed film member without any fixing or fusing process and hence, the toner can be removed from the film member afer projection. During charging and toning, the film member is maintained in darkness.The electrophotographic film member is mounted in a window formed in a disc arranged for stepwise rotary translation from station to station. The electrophotographic film member comprises a thin film coating of an inorganic, photoconductive, electronically anisotropic material, one example of which is a specially sputtered cadmium sulfide bonded to a thin film layer of ohmic material which in turn is bonded to a thin stable substrate member preferably formed of plastic sheeting. The total thickness of the photoconductive coating is about 3,000 Angstroms and the ohmic layer is about 500 Angstroms. The film is durable with a hard abrasive resistant surface, is highly transparent and has high photoelectric gain. Its speed and sensitivity are such that a projectable transparency is formed almost immediately to enable projection of the received image almost as soon as it is received from the image source. The speed of the stepwise translation preferably is sufficient to provide successive projectable transparencies to the projection station fast enough to fall within the image retention capabilities of the human eye, thereby effecting a cinematographiclike display.

    Abstract: An electrical motor includes a stator housing having a toroidally shaped inner cavity. A plurality of stator electromagnets are mounted along the cavity wall in a plurality of parallel helical paths. A plurality of rotor members are rotatively mounted at fixed, spaced-apart angular positions around a ring shaft whose axis is coincident with the axis of the toroidal cavity. Each rotor member includes a plurality of permanent magnets mounted around its circumference. A linear output shaft has one end connected to the ring shaft and its other end extending out of the stator housing. By properly energizing the stator electromagnets, electromagnetic fields set up by them and the rotor magnets interact to produce torque which causes the rotor members to rotate about the ring shaft and to precess laterally causing the ring shaft, and attached linear output shaft, to rotate relative to the stator housing. The toroidal configuration of the motor provides a larger volume electromagnetic field interaction space than conventional cylindrical motors which yields higher output powers and higher torques. The motor, which also has an inherent speed reduction feature, may be operated in reverse as an electrical generator.

    Abstract: Small particles are produced by supporting a pair of elongated consumable electrodes coaxially in a housing so that corresponding ends of the electrodes are spaced apart across a gap. A potential difference is applied to the electrodes so that an arc ignited in the gap between the electrode ends gasifies the electrode material at the end. The gas is then cooled so that the gas condenses into small droplets which solidify into solid particles which are collected at a collection site.

    Abstract: A toroidal drive system includes a housing composed of first and second mating housing sections having interior walls which cooperate to define a plurality of parallel, helix-like races inscribed in a torus having a circular axis. The two mating housing sections are secured together and a plurality of rotary elements are fixedly spaced apart along that axis, the elements each having an axle fixed at the axis and a plurality of removable, radially extending teeth rotatably encircling the corresponding axle, each tooth of each rotary element engaging in a different one of the plurality of races. A worm is mounted for rotation in the housing about an axis substantially perpendicular to the circular axis, that worm engaging at least one tooth of each of the plurality of rotary elements. Power take off means are connected to all of the axles and extend without the housing. Access holes are provided in the housing section walls at the bottoms of the races, the holes being larger than the teeth engaged in the races so that the housing sections can be mated around the rotary elements while the elements are missing some teeth and secured together after which the missing teeth may be installed on the rotary elements through the access holes by rotating the worm to align the missing tooth positions of the elements with the holes. Methods of making and assembling the drive system are also disclosed.
