An ocular pointing and tracking device for complete hemispherical scan capability. The device may be used for receiving a sensor at a target and making necessary corrections for relative target motion.

An easy-to-use technique for specifying measurements of a document to be printed uses a pointing method, such as a cursor which is moved around a display screen by means of a pointing device having a select button. The pointing cursor is moved to each desired location in a predetermined sequence, and the select button is pressed. The values of the measurements so selected are calculated based on the relative position of the pointing cursor at the time the select button is pressed.

A pinch-pointing machine for forming pilot ends with screws or like fastening devices which comprises a pair of die-heads adapted to move toward and away with respect to each other, a pair of forging dies mounted respectively to the pair of die-heads so as to pinch-point shortly cut blanks therebetween, and a feed dial adjustably movable in three-dimensional directions for feeding the blanks to a center position between the forging dies by means of a plurality of regularly spaced engagement groo...

A pointing and control device for moving a cursor on a visual display and for controlling various operations, being operated by hand and finger movements, including both fine movement control and gross movement control; the assembly includes a graspable outer cover and an inner puck with a finger cup movably supported by a series of elements, a laser beam movement detector consisting of high and low frequency scanners, drivers, lower and upper photodetectors and signal amplifiers and processors....

Apparatus for providing accurate pointing of instruments on a carrier vehicle and for providing isolation of the instruments from the vehicle's motion disturbances. The apparatus includes two assemblies, with connecting interfaces, each assembly having a separate function. The first assembly is attached to the carrier vehicle and consists of an azimuth gimbal and an elevation gimbal which provide coarse pointing of the instruments by allowing two rotations of the instruments relative to the carr...

A positional transducer element and an orientation of two positional transducer elements within an X-Y position indicator for a display system. An X-Y position indicator which may control the movement of a cursor over a display on a cathode ray tube. Signals are generated from the indicator indicating its position to cause the cursor to be displayed on the tube at a corresponding position. X and Y position wheels are mounted within the indicator at a predetermined relationship to each other and ...

An articulated device to be used for pointing satellite antennas, especially of data relay or like telecommunication satellites. It comprises at least three articulations rotatable about their respective axes coupled in pairs by arms. These rotation axes intersect at a remote virtual rotation center coinciding with the antenna's focus. The device allows pointing of an antenna by moving its reflector, while maintaining the antenna feed at its focus, thus avoiding antenna radiation pattern distort...

Apparatus for grinding conical points on the ends of paper sticks. The sticks are fed one at a time in spaced relation to pockets on an endless carrier. The sticks have one end extending beyond a lateral edge of the carrier which are ground to a conical point by an abrasive belt supported at an acute angle to the axis of the carrier. The sticks are rotated counter to the direction of travel of the abrasive belt in the carrier pockets by upper and lower contact belts as they are ground to expedit...

The wire pointing machine comprises two grooved rolls which are supported in a gear ring pivotable about a horizontal axis. Teeth are provided on end trunnions of the grooved rolls which mesh with a common gear rack which is directly powerdriven.

A grinding machine with a high production rate for pre-pointing drill bodies and the like in automatic duty cycles wherein separate grinding heads and a chuck head are respectively shiftable to and from a working position to grind both ends of the drill body simultaneously. The chuck head includes a special through-feeding rotary chuck which is journalled at its periphery and through which the work pieces are loaded and unloaded sequentially and unidirectionally by a fast-acting loading plunger ...
