Patent number: 4163499Abstract: Apparatus for opening a cassette, of the type which carries a sheet of X-ray film, to allow the film to move into processing equipment, without requiring a darkroom. The apparatus includes a lighttight housing containing inclined guides for receiving the cassette, and pins at the bottom of the space between the guides, that can engage latches on the cassette to open it. The cassette is forced against the pins by a cover on the housing, which pushes on the cassette as the cover approaches its fully closed position, so the pins unlatch the cassette which opens to allow the film sheet to drop out.Type: GrantFiled: June 13, 1977Date of Patent: August 7, 1979Assignee: E.

Patent number: 4018033Abstract: A system for enabling X-ray films, of the type primarily used in the dental and medical fields, to be handled in daylight for exposure to X-rays. The system utilizes identical film sheets emulsion coated on one or both faces, each sheet having a notch, displaced from the sheet center line, formed in one edge thereof. A stack of sheets is packed in an opaque envelope with the sheets being alternated so that all of the notches lie along a common stack edge arranged in two parallel rows, the notches in adjacent sheets lying in different rows. The system includes a light tight dispenser which receives the envelope and is capable of being operated to strip the envelope from the film sheet stack. The dispenser includes a pair of rotatable selector cams, each aligned with a different row of notches. A spring mounted back-up plate urges the film sheet stack against the selector cams with the two selector cams respectively bearing against notched and unnotched portions of the top sheet.Type: GrantFiled: October 9, 1975Date of Patent: April 19, 1977Assignee: Cubic Productron Inc.Inventor: Gunter Schmidt

Patent number: 4012753Abstract: A reliable machine for developing film, which minimizes the possibility of damage to the film surface and which provides close control of processing conditions. A film strip is pulled by a detachable member attached at the front end of the strip, and is guided along the machine by rollers spaced along the film path, with each roller having a film-supporting surface at each end and a wide cutaway portion between the film-supporting surfaces so that each roller touches only edge portions of the film. Chemicals in the tank are replenished by a system which includes a plunger that moves down into the tank to cause some of the chemicals to overflow into a drain and which then moves up out of the tank to lower the fluid level therein, and a bottle with an open lower end which supplies chemicals to restore the fluid to its original level.Type: GrantFiled: May 2, 1975Date of Patent: March 15, 1977Assignee: Cubic Productron, Inc.Inventor: Gunter Schmidt

Patent number: 3950103Abstract: A method and apparatus for numerical determination of the distribution of magnitude and phase of a time harmonic electromagnetic, particularly an optical, wave field by using the wavefront of a reference wave as the optical reference surface and by introducing additional information to the recording process such that the field becomes uniquely determined and this is realized by the recording of three interference fringe patterns which belong to variations of the reference field distribution. A reference field is chosen whose spatial distribution is similar to the unknown field whereby fringes are obtained the position of which varies slowly with the recording coordinates. The recorded data are numerically evaluated and this may be done conveniently in a computer. After these measurements are made the reference beam is shifted by an optical element e.g. a prism, gaseous wedge, electro-optical diffraction device placed in the reference optical path and a second set of measurements is made.Type: GrantFiled: June 21, 1974Date of Patent: April 13, 1976Assignee: Canadian Patents and Development LimitedInventor: Heinz Gunter Schmidt-Weinmar
