Apparatus and method for the visual display of an object, such as an aircraft, at continuously variable attitudes comprising two hologram films of the object made in wrap-around 360.degree. fashion on axes through the object and normal to each other to store object images comprising a complete spherical view of the object and the provision of scanners, a laser beam source, reflectors and an instructor's control panel of amplifiers and switching circuits to direct the laser beam to the film havin...

Fluidic apparatus which is simple, accurate and inexpensive, for checking whether a dimension of an object, such as the thickness of a bottle stopper, is within a predetermined range of values. A cylinder is provided with a pair of axially spaced-apart ports, and a piston is mounted reciprocably within the cylinder and provided with a spool having a length exceeding the length required to block off both ports by an amount substantially equal to the magnitude of the permissible range of dimension...

A method for preparing and an apparatus for supporting appliances thereon, the support being a pair of base members with means on the top side thereof for mounting an appliance thereto. Each of the base members is comprised of a hollow member having disposed at preselected portions therein resilient foam materials which maintain the base members in a preselected configuration and support the appliance mounted thereto.

Small objects, such as pharmaceutical capsules from a production stream, are counted with speed and accuracy. The objects are delivered to a hopper from which they are picked up by a rotating suction drum and transported through an orientation means to an object pick-off or drum stripping means. Following separation from the drum, the objects pass sequentially through an electro-optical sensing device which delivers electrical pulses to an electronic counter means which has the ability to displa...

Apparatus and circuitry for positioning a mirror at a desired position includes an electric to rotary motion transducer means connected with the mirror which is controlled by a signal obtained in response to an electrical positioning signal and a feedback signal derived from the actual mirror position. An electro-optical sensing means responsive to the actual position of the mirror provides the feedback signal. The circuitry is automatically calibrated.

The invention is directed to a system for routing assorted items to preselected destinations. The items to be routed are deposited at any of various reception areas and automatically routed to a particular final destination depending upon the nature of the item. Each item carries a machine readable label, such as a bar coded label, which is scanned by an appropriate scanning mechanism. Information encoded onto the label is then obtained by the scanning mechanism and is injected into appropriate ...

An apparatus for projecting an object is described. By installing in the apparatus a number of electric bulbs of comparatively lower voltage and larger current, this new type of apparatus for projecting an object can be used in the daytime by illuminating uniformly the overall face of the object capable of placing on the top of the apparatus with a very large volume of rays. Also, in order to eliminate the increased temperature in the apparatus, the ventilating arrangement is provided.

3. An object locator system comprising, means emitting signals, means for ceiving signals returned by distant objects, means for storing received signals, a narrow bandwidth analysis channel, means for controlling the playback of stored signals whereby signals stored intermittently for a selected range are played back continuously without substantial intervening time interruptions, and means for varying the frequency of playback signals whereby they are held within the bandwidth of the analysis ...

A device for testing the contour of an object by determining the relative locations of test portions on the contour. In this device means are provided for moving the object to be tested through the idle path at a high speed and for bringing about the testing contact at a considerably lower speed. To this end, a first and a second sensor are so moved into the range of the object that the second sensor is within the range of the object contour and the first sensor is within the range of the test p...

Apparatus is disclosed for measuring the movement of an object comprising an optical imaging device for producing an image of said object, a grating structure positioned to receive the image of said object produced by said imaging device, drive means for producing a periodic relative movement between said grating structure and the image formed thereon, means for generating reference signals corresponding to said periodic relative movement, photoelectric receiving means positioned for receiving l...
