Abstract: A novel light wherein the source of illumination is an array of light emitting diodes mounted on a printed circuit board. The board is contained within an impact resistant housing. Several different embodiments are disclosed for the housing, including injection molded and extruded variants.

Abstract: An annular locking ring for use on an aircraft wheel that has a pair of separable wheel sections wherein the locking ring has a lobe section and a leg section. The cross-sectional shape of the leg section has a pair of spaced linear portions that are interconnected at their one ends while the cross-sectional shape of the lobe section has a curvilinear portion and a linearly extending portion that intersects one of the linear portions of the leg section. The curvilinear portion of the lobe section has one end that merges with the other one of the spaced linear portions. The extension of the one linear portion of the leg section makes an acute angle with the linear portion of the lobe portion. Alternatively, the lobe section may have two spaced linear portions separated by the curvilinear portion with one of such linear portions merging with one linear portion of the leg section and with the other one of such linear portions of the lobe section intersecting the other linear portion of the leg section.

Abstract: An improved torque lug drive for a multidisc brake and wheel assembly having greater resistance to torque loading than earlier designs at lower weight. The torque transmitting beam is mechanically secured to the radially inner surface of the wheel rim adjacent the wheel rim flange, for example, by a threaded fastener. A shear pin transmits torque load from the torque beam to a boss provided on the radially inner surface of the rim at a point between the wheel rim flange and the web of the wheel.

Abstract: A device for both entering and displaying information includes imaging circuitry in which a plurality of elements each has a visual characteristic which is visible at a writing surface and which depends on electrically stimulating the element via conductive circuitry, the imaging circuitry is arranged to produce electrical manifestations at the conductive circuitry in response to writing stimuli, and the device also includes control circuitry which delivers electrical signals to the conductive circuitry to form an image and converts the electrical manifestations into digital form.
