Abstract: A wide-field-of-view projection display comprises a circularly symmetric lens and an array of light emitters, positioned along the focal circumference of the circularly symmetric lens so that light from each of the light emitters is substantially collimated by the lens in a different direction. A ray-diverting means, such as a slab waveguide or a reflector, ejects the collimated light out of the plane of the lens to the viewer. The planar circularly symmetric lens has no aberration, allowing adjacent views to be seamlessly joined because they can all be diffused by the same angular amount.

Abstract: A clockspring driven permanent magnet generator comprising a bobbin-mounted coil, inner and outer frame members defining diametrically opposite pole pieces and a structure which cages or essentially surrounds the bobbin and coil combination. A rotor comprising the integral combination of disc and shaft portions carries a two-pole permanent magnet and is, in the assembled structure, located such that the shaft portion extends through the frame structure and the caged coil to place a permanent magnet between the pole pieces which are defined by the caging frame structure. A flat wound clockspring drives the shaft portion relative to the frame structure to induce a short duration voltage in the coil which can be used, by way of example, as an electronic fuse in an explosive device such as a hand grenade.

Abstract: An electric motor utilizing permanent magnets, wherein the permanent magnets produce a flux circuit in a first direction and shunt elements whereby the magnets and shunt elements rotate relative to each other wherein the shunt elements sequentially interrupt the magnet flux circuit to minimize generated flux circuits tending to rotate the motor in a direction opposite to the primary direction of motor rotation.

Abstract: An apparatus imparts movement to a fluid dispersing nozzle with a mechanism for converting rotational movement about an axis of rotation into orbital movement about the axis of rotation, and an elongate member is connectable to the mechanism at one end and is connectable to a fluid nozzle at an opposite end from the mechanism. The orbital member provides orbiting movement of the opposite end in response to rotation of the mechanism about the rotational axis, and provides stationary centered positioning of the opposite end in response to a non-rotating mechanism. A speed multiplier transmission or gearbox can be provided between the motor shaft and drive spindle if desired. A separate mixer is positionable within the member and is moveable longitudinally with respect to the member during use. The mixer includes a valve member connected to one end for movement relative to a valve seat defined by an inner surface of the cone.

The drive pin can be moved within the body to engage a cam follower of the locking arm. The drive pin can be supported during movement by one or more rollers mounted in the body. The drive pin can include a pin body and a pin member moveably associated with one another to selectively define the position of a cam surface.

Abstract: A sealing apparatus for effecting a temporary seal against an elongate object. The object is placed in a chamber(17) and supported between inlet and outlet apertures in the walls of the chamber. A resilient seal (32) is placed at the point where the object passes through one of the apertures. A piston (34) is located on the remote side of the seal being operable to compress the seal towards the relevant aperture thereby deforming the seal laterally into contact with the object to seal the periphery of the object. When the piston is released, the seal reverts to its relaxed condition thereby enabling the object to be moved between the two apertures.

Abstract: The architecture of an automotive wiring, power distribution and accessory control system is described. The system comprises semi-custom two-tier nodes which are distributed in locations around the vehicle to service load devices associated with or found in different regions of the automobile topology. A multiplexed control network interconnects the nodes along with a two-wire bus. Each node consists of a first common board carrying a microcontroller and a basic number of FET driver switches associated with a basic level of accessorization for that region of the vehicle. Each node further comprises a second larger pass through board which supports the first common board in spaced parallel relationship therewith and which carries terminal connectors. The larger pass through board has vacant locations for the addition of FET drivers needed for higher levels of accessorization. These locations are preconnected to the microcontroller but are unused in vehicles with lower levels of accessorization.

Abstract: The specification discloses a rapidly-opening hunting blind comprising a fabric enclosure including an opening and moveable side panels at least partially defined by a resilient framework. The moveable side panels at least partially define a closure for the opening. The hunting blind has a closed condition, wherein free ends of the side panels are releasably connected to at least partially define a tent-like closure for the opening, and an opened condition, wherein the side panels extend radially outwardly and expose the opening. The resilient framework is biased towards the opened condition of the hunting blind such that when, in the closed condition of the hunting blind, the connected free ends of the side panels are released, the side panels tend spontaneously away from each other towards their radially extending configuration.

Abstract: An apparatus and method for changing the volume of the watertight hull of a ship in the light or no cargo condition to achieve the required ballast drafts. At least one trunk extending longitudinally from a first end at a bow of the ship to a second end at a stern of the ship. The first and second ends of the trunk connectible to the water surrounding the ship by operation of an inlet valve and an outlet valve adjacent each end. When in the light condition, or no cargo condition, the valves at each end of the trunk or trunks are moved to an opened position to reduce the volume of the watertight hull in order to achieve the desired ballast draft. While the ship is in motion, sufficient pressure differential exits between the bow and the stern of the ship to exchange the volume of water in the trunks over a period of time. Preferably, the fluid flow through the trunks exchanges the water at least approximately every hour when the ship is moving at normal speed.
