摘要： A journal bearing for a rotating mass, wherein a lubricating fluid is disposed in a bearing cavity defined between an inner bearing member and an outer bearing member. One of the bearing surfaces is provided with at least two sets of grooves, the grooves of each set adapted to impel said fluid axially with respect to said cavity towards a common point.

摘要： A device for retracting and aligning the brush members of a brush block assembly with respect to a slipring assembly, wherein a cylindrical member provided between the brush lock assembly and the slipring assembly has a plurality of slots for receiving the brush members, and an arcuate groove registering with each slot. The cylindrical member is rotatable with respect to the brush block assembly so that each brush member can be transferred into said groove to uniformly retract the brush members.

摘要： The disclosed embodiment of the present invention is a method of storing pictorial information on and retrieving pictorial information from a movable storage media to permit rapid access and retrieval of such information for displaying either the whole or a submultiple of the whole of the pictorial information in a minimum of time. The disclosed method comprises writing blocks of such information on a magnetic drum, with each block being formed of one or more lines of the scanned information. The blocks are arranged in step fashion on the drum with each successive block being spaced along the direction of travel of the drum a distance equal to the line length of the smallest picture to be displayed. In the disclosed embodiment, each block is formed of four scan lines written in 16-bit parallel format on the drum, and the spacing of each block is equal to the distance occupied by onefourth of a scan line of information. Since the scanned information is greater than the displayed information, that portion of the information which is to be displayed is read from the drum, compressed by means of logic circuits, and supplied to a display storage. The information in the display storage is continuously read and supplied to a CRT for display to an operator.

摘要： A rotating disc memory assembly is provided for electronic digital computers, data processors and the like, which is simple and inexpensive to construct, which requires a minimum number of parts, and yet which provides for a precisely determined spacing between the inner ends of the electromagnetic transducer heads carried by the housing of the assembly and the surface of the rotating memory disc. The assembly to be described includes a rotating hub, which is precisely positioned with respect to the inner surface of the housing mounting plate for the aforesaid heads, and a wedge-shaped annular C-clamp which holds the disc memory firmly against a peripheral shoulder of the hub in an accurately spaced relationship with respect to the inner ends of the heads mounted in the aforesaid mounting plate.

摘要： A system for recovering the drift coefficients of two navigational gyros for a vehicle, each of the gyros having a rotatable outer casing and two input axes, wherein the gyros are positioned so that their spin axes extend at an angle to each other and a precession torque is applied to the gyros to maintain their spin axes in a predetermined spatial position. The casing of each gyro is rotated about an axis parallel to its spin axis to predetermined angular positions, so that a drift coefficient can be established for each input axis.

摘要： The disclosed embodiment of the present invention is a motion picture projector which includes a simplified threading and loading apparatus and several novel failsafe devices. The projector is provided with a film trap gate, a plurality of sprockets for forming loops in the film on opposite sides of the gate, and tensioning means on opposite sides of the gate for maintaining a predetermined tension in the film strip. The tensioning means are moveable to a ''''load'''' position with respect to the associated sprockets on opposite sides of the gate to form a substantially straight line path between an associated reel and the sprocket adjacent the film trap gate to permit simplified loading and threading of the film on the projector. In addition, several failsafe switches are provided which maintain the drive system of the projector inoperative until all of the sprockets, pressure rollers, and film trap gate are in the operating position. Each of the reels are provided with a tensioning motor associated with the tensioning means and are further provided with brakes which engage the reel shafts upon the occurrence of a power failure or in the event that one of the interlock switches is actuated.

摘要： Apparatus for generating a realistic wide-screen visual display for an aircraft simulator with realistic perspective throughout plural widely different phases of simulated flight by scanning a plurality of different successive types of transparencies with a flying spot scanner to derive video signals to drive television display projectors, including the scanning of a pair of transparencies to provide a background terrain elevation image without topographical features, scanning of a second type of transparency to provide an image of an airport or the like to be inset into the background image and distorting the inset image as simulated range and elevation angle from the airport vary, scanning a third type of transparency to provide a different type of inset image during simulated approach and landing and distorting that inset image in accordance with deviation of the simulated aircraft from a reference glideslope, and scanning a fourth type of transparency to provide a panoramic view of the airport during simulated taxiing and parking maneuvers, with means for automatically controlling the successive scanning modes with signals from a flight computer.

摘要： A seal assembly for a hydraulically operated cylinder comprising a pair of sealing members acting between the cylinder end cap and the operating shaft to seal the hydraulic operating fluid from the ambient fluid. A pressurized fluid is disposed between the sealing members and acts on the shaft to control the pressure differentials across each of the sealing members.
