A method for molding is disclosed in which a fluent molding material is flowed into a cavity of a mold, which is then shaped into a configuration defined by the mold. Control signals which are applied by operating a master controller to control the transfer of heat with respect to the molding material, in order to predeterminately control the temperature of the molding material as it flows into and is retained within the mold. The temperature of the molding material flowed into the cavity is sensed, and feedback signals are generated relating to the sensed temperature. The feedback signals are compared to reference signals indicative of a desired molding material temperature and a further control signal is generated which is applied to control the variables of the molding operation, including the temperature of the molding material.
摘要:
An automatic scanning apparatus and method for detecting the presence of one or more objects in an image field under investigation or inspection. Electro-optical scanning means, such as a television camera, is employed to scan an image field and generate output electrical signals which vary in accordance with variations in the optical characteristics of the matter and objects in the image field scanned. Such signals are computer processed and analyzed to generate coded electrical signals which define optical characteristics of portion of the image field scanned, such as objects or the images of objects scanned, their shape, color of a combination of color and shape. Electronic means is provided to generate further coded electrical signals which indicate the presence of one or more objects in the image field scanned and may be used to effect intelligent indications thereof, to control one or more devices such as a motor or motors, and/or to provide information for computational purposes to be processed and utilized by a computer. In one form, that shape of an object or objects is detected and coded signals generated are employed to effect a comparison of such shape with information relating to the shapes of known objects to identify the object or objects scanned. In another form, the color or surface characteristics of an object is detected and resulting signals indicative thereof are compared with information derived from a memory to identify either the object or its color or surface characteristics. In a third form both shape and color are detected and compared with recorded information for identification purposes.

High density recording systems and methods are disclosed which employ a radiation beam to form spot-like recordings in record members such as discs, tapes and cards. The angle, offset or cross-sectional shape of the recording beam can be varied so as to vary the angle, offset or shape of the corresponding recordings in the record member. The recorded information can be electro-optically or magnetically detected and discriminated from each other to provide high density recordings of alpha-numeric characters or digital data. Enhanced detection scanning is effected by ultrasonically vibrating the laser or an optical element, such as a prism or mirror receiving the reading light beam, in a manner to cause it to scan back and forth laterally to the record track as a longitudinal scanning movement is effected parallel to the longitudinal axis or centerline of the track. The reflected light is detected, computer processed and analyzed to effect proper detection of the recordings to generate correct data therefrom.
摘要:
An automatic scanning and control apparatus determines the location of a predetermined segment of an image field being scanned. The predetermined segment presents an image which is optically differentiatable from the surrounding area of the image field. The apparatus includes a beam device for selectively scanning the image field and producing an output signal thereof. The beam device includes means for modulating the output signal in accordance with variations in the image field. The predetermined segment of the image field causes modulation of the output signal of the beam device by providing an inflection therein when the beam scans across the segment. An analyzing circuit is adapted to accept the output signal from the beam device. Means generate a locating signal in predetermined time relation to the scanning. Comparator means compare the inflection in the output signal with the locating signal so that the location of the predetermined segment of the image field can be determined. A method compares an image field to be inspected with a standard image field. A standard image field is scanned with a beam and a video signal is modulated in accordance with intensity variations in the standard field. The video signal is recorded on a recording member. The field to be inspected is then scanned by the beam and a second video signal is generated. Both the video signals are reproduced and passed to a comparator means. A point to point comparison is made between the inflections and variations in each signal resulting from the scanning image areas of contrasting intensity by generating pulse signals during the intervals that the areas do not coincide. The pulse signals are then automatically analyzed.
