Abstract: A bar-type display utilizing incandescent lamps stacked in a linear array in a metallic lamp block preferably of aluminum shaped to form a parabolic reflector configuration along its length and a tongue and groove configuration for attachment to an insulating connector block. Fins are provided on each side of the block for heat dissipation and grooves are formed transversely of the block through the parabolic reflector configuration at intervals into which barrier plates are inserted to sectionalize the block into separate reflectors for each lamp. To disperse the radiated and reflected light, a plastic diffuser is placed across the top of the reflector configuration, which may be colored to color the transmitted light, and to provide anti-reflective qualities for non-glare viewing.The insulator connecting block is molded to the lamp block and the lamp pins are arranged so that alternate lamps may be powered by separate power supplies for redundancy purposes.

Abstract: A hand-operated pyrotechnic device has a tubular handle and, slidable telescopically therein, a tubular striker supporting a firing pin. The striker is rotatable from a `Safe` position to an `Armed` position, and movable axially, by impact, from the `Armed` position to a `Fire` position. A resilient detent prevents movement from the `Armed` to the `Fire` position unless the applied impact force exceeds a predetermined value. Further resilient detents prevent unintentional arming of the device.

Abstract: The subterranean fragmented and pervious zone is formed beneath an overburden which, as a first step of the process, is lifted as a substantially monolithic land mass to produce a void space and a free space proximate the rock to be fragmented, the raised overburden thus providing a substantially impervious lid or closure for the fragmented zone as formed by the present invention. Explosive charges are then placed proximate to and for blasting against the free face formed on raising the overburden. The charges are exploded to fragment the rock to distribute the space, thus producing fractured, pervious rubble-ized rock in a defined and enclosed zone. Different techniques are disclosed for the critical raising of the overburden and subsequent fragmenting of the rock.

Abstract: An image converter is fabricated by processing its photocathode within an evacuated chamber free of harmful contaminants. The evacuated chamber, in turn, is housed along with the remaining structural components of the intensifier in a further closed chamber that may be evacuated at the proper time in the fabricating cycle. The proposed photocathode is released from its enclosing chamber for only that short period of time required to effect a transfer from that chamber into mating engagement with the remaining envelope portion of the intensifier. When these components have thus been assembled, they are integrated to complete the device.

Abstract: A weapons system is described in which an explosive shell, fired from a cannon or other launch device, is precisely guided to a target to ensure a sure hit and kill capability. A shell having no on-board guidance mechanisms or propulsion devices, but having its tail section coated with a material vaporizable by a laser is employed. A laser beam is directed toward a target, and the shell is fired into the beam toward the target. The vaporization of the coating on the tail of the shell by the laser beam generates forces which, due to the aerodynamic design of the shell and the shaping of the energy distribution within the laser beam, maintain the shell in the path defined by the laser beam to guide the shell into contact with the target.
