Abstract: A film cartridge for enclosing a photosensitive film disk within a light-tight chamber defined by opposed walls which are sealed together to encapsulate the film disk. When the cartridge is positioned in opening apparatus, force-applying members inserted through passages in one of the walls of the cartridge are moved into contact with the opposed wall. Continued movement of the members displaces the opposed wall sufficiently to rupture it and/or a seal joining the walls. A wall-separating member of the opening apparatus is inserted into the rupture and moved between the opposed walls to extend the rupture and space the walls by a distance sufficient to permit the film disk to be removed from the cartridge.
Abstract: A photographic cartridge assembly includes a photosensitive film disk rotatably received between opposed parallel walls of a thin cartridge casing. The casing is adapted to be opened, to release the disk for processing and printing, by prying the casing apart until it fractures at one edge and then tearing the casing from the fracture toward the opposite edge. In order to insure that the resulting opening is at a predetermined location in the casing, and is large enough to remove the disk, channels are provided in a casing wall to lead the tear along two paths extending oppositely around the periphery of the disk from the one edge to the opposite edge.
Abstract: Method for sterilizing soft contact lenses and the like using methoxymethane while the lenses are in a liquid-wetted state. Methoxymethane on the water-wet surface for a sufficient time kills the microorganisms (bacteria, molds and yeasts) that invade and are entrapped in the pores and irregular surfaces of the hydrophilic materials from which such soft contact lenses are made. An easily portable apparatus for applying this sterilization technique to the lenses is also disclosed. It includes a lens holder that can be held in a chamber that can be pressure-isolated to receive the methoxymethane gas from portable sources. In one form, an indicator shows that the lenses are under sterilization pressure. This novel arrangement dispenses with the inconvenience of using prolonged steaming, or questionable sterilization in disinfecting fluids which may affect the composition of the soft contact lens.

Abstract: A preregistered instant-processing film unit including an internal dark slide and adapted for use in exposure apparatus having processing rollers. The film unit includes a leader that carries "saddle detents" or detent shims located on opposite sides of the dark slide and having a caliper greater than the thickness of the dark slide. The shims are positioned to receive the rollers, both to provide sufficient clearance for removal of the dark slide therebetween and to hold the rest of the film unit in position while the dark slide is removed.
Abstract: A splint to be applied by a policeman, paramedic, or fireman during rescue operation to a suspected cervical spine injury victim. The splint is designed for quick on-site installation to immobilize the head and cervical area before any attempt is made to move the victim.The splint is composed of two half sections. Each section is mounted on a shoulder harness and is designed to be fitted independently on either side of the head. The two sections are then connected to form a cage surrounding the victim's head. The head is secured within the cage by means of inflatable neck pillows. The splint may be fitted with an accessory designed to apply traction to the cervical vertebrae during emergency room treatment.
Abstract: Atomic hydrogen, for use as a fuel or as an explosive, is stored in the presence of a strong magnetic field in exfoliated layered compounds such as molybdenum disulfide or an elemental layer material such as graphite. The compound is maintained at liquid temperatures and the atomic hydrogen is collected on the surfaces of the layered compound which are exposed during delamination (exfoliation). The strong magnetic field and the low temperature combine to prevent the atoms of hydrogen from recombining to form molecules.

Abstract: A method for regulating vehicular traffic over a network of itineraries travelled by various vehicles such as railroad trains, or other public modes of transportation. On board, computer assisted vehicle control processes are advantageously combined with traditional time-table scheduling and modern centralized traffic control concepts. Simplified audio radio communications alleviate the need for intensive track equipment. Monitoring and signaling devices are limited to those dictated by safety rules and regulations. In order to limit to a minimum the exchange of data between each vehicle and the traffic control, a set of predetermined timetables are stored on board each vehicle. Traffic instructions are reduced to two elements, the identification of the assigned timetable and a time lag constant to be uniformly added to the time entries of the assigned time-table.
