Abstract: A two element lens system provides a close up lens system which may be installed on a camera either above or under water, and allows the camera to be used in air and underwater without a means for lens position adjustment. The system uses two meniscus elements in a holder attachable to a receptacle on a camera body over an opening closed by a transparent window element. The lenses define therebetween a sealed compartment and a compartment which is located between one of the lenses and the window element having a vent which allows the water or air to flow into or out of that compartment. The curvatures of the lenses are selected so that the lens system has the same focusing power and focuses an image in an object space at the same image plane (the film plane with the aid of the camera's lens) when the vented compartment is filled with air or with water.

Abstract: The invention is generally accomplished by providing a method of forming prints with colored borders. This is generally accomplished by exposing a color imaging substrate to colored light in a pattern at least partially encircling a central image. In a preferred form of the invention, the image is a color photographic image that is surrounded with a color image that is printed peripherally of the colored image on the same sheet of photographic paper. The colored border may suitably be a color such as gold, silver, or a color contrasting with the color print.

Abstract: A boundary layer disturber for removing heat from the platen of a copier is in the form of an improved scanning reflector which has a portion thereof in the form of a "scoop". During scanning motion, the reflector entrains air flow which disturbs and peels the thermal boundary layer from underneath the platen glass, thus passively improving platen glass cooling. Also, the reflector is contoured to allow air to entrain over the lamp assembly, resulting in enhanced cooling. As a result of changing the form of the reflector there is increased cooling characteristics in the optics cavity, thus allowing blowers with lower power and noise levels to be utilized in the optics cavity.

Abstract: A novel type of liquid filled kaleidoscope with a dual housing that offers the experience of viewing first, a multiplicity of brilliant and symmetrical patterns visible through the eyehole of the kaleidoscopic instrument and second, a kinetic decoration visible from a vantage outside the kaleidoscope along its entire length. Both these effects are created by the same suspended particles flowing freely in a liquid which fills not only the object cell, but also the adjoining chamber located between the inner casing and the interior wall of the transparent main cylinder. This design also allows the viewer to systematically increase or decrease the number of particles visible in the mirrors, by raising or lowering the distal end of the kaleidoscope thus allowing particles to flow into or out of the object cell and the adjoining area. An optical illusion that there is no mirror chamber inside the kaleidoscope can also be created by the dispersion of the same particles against the backrop of a reflective surface.

Abstract: A copying apparatus has a receiving station, an exposure unit, a developing unit, an inspection station and a pricing unit with a memory. A master to be reproduced arrives at the receiving station together with an order for the reproduction thereof. The order has a coded order number which is read by a scanner at the receiving station and entered in the memory to establish a data set. The exposure unit is inoperative upon arrival of the master at the receiving station and is activated only upon entry of the order number. The master is then drawn into the exposure unit where copy material is exposed to light which has illuminated the master. The copy material is developed in the developing unit and the resulting copies are delivered to the inspection station where they are inspected for quality. The number of copies made is entered in the memory and incorporated in the data set with the order number.

Abstract: A dome-shaped motion picture projection screen is constructed from an external supporting frame and a plurality of panels that are clipped to the frame by a series of individual fasteners that are hooked into the perforations in the panel and clamped to the frame. Each fastener has a L-shaped fastener body with a pair of hook-shaped pins that project from one end of one limb so that they can be hooked into the perforations in the panel. A screw extends through the other limb parallel to the first limb and can be tightened against a supporting frame member to secure the panel to the frame. By carefully controlling tightening of the screw, localized flattening of the panel at the positions of the hooks can be avoided. The ends of the hooks are so small as to be virtually invisible to the audience.
