Abstract: An apparatus and method for acquiring and storing video picture frames at a first rate and for reading and displaying said frames at a second rate which is a selectable integral of the first rate implements the steps of: converting analog picture elements to digital words, storing at least one frame of digital words in a first memory at the first rate, reading the frame of digital words out of the first memory at the first rate in interlaced scan format, storing the frame of digital words read out of the first memory in a second memory at the first rate, reading said frame of digital words out of the second memory at a second rate which is a selectable integral multiple of the first rate, converting the digital words read out of the first memory to analog picture values and putting out said converted analog picture values in interlaced scan format, and converting the digital words read out of the second memory to analog picture values and putting out the converted analog picture values at the second rate.

Abstract: A memory stores and repetitively plays back for display an continuously repeating, consecutive sequence of picture frames derived from a source. The memory includes an input for receiving digitized picture element values in a serial bit stream and for framing the stream into consecutive constant length pluralities of digital picture element words. A read/write solid state semiconductor frame memory array is arranged as a ring for storing and playing back a predetermined number of the consecutive video picture image frames. An output receives constant length pluralities of digital picture element words read from the memory array and converts them into an analog picture signal for display. A read/write memory array control controls writing to and reading from the frame memory array so that a selected segment of consecutive video picture frames may be repeatedly played back without interruption at a real time image display rate.

Abstract: An analog data stream is monitored as a series of blocks. A ring memory array digitally stores the blocks and repetitively loads and unloads the blocks. A freeze switch disables loading of the latest blocks. A block identifier puts out a unique block identification value for each block put out by the memory and is responsive to the freeze switch, so that when loading stops, each block put out bears the same identification value. The invention is particularly well suited to handling of television frames.

Abstract: Apparatus for forming the rim on a foam plastic container such as a cup by use of a segmented rim former. The cavity in the rim former is contoured so as to produce a curled rim that is flat on the top. The flat top of the rim is parallel to the bottom of the cup.The apparatus comprises a segmented rim former with a combination of linear and curved surfaces that form a noncircular container rim.

Abstract: A video recorder and playback system for storing video information consisting of video frames successively presented at a standard frame rate, each frame having first and second interlaced video fields, and for playing back the video information in a desired sequence to produce a video output signal, providing either slow motion or normal motion effects when viewed on a monitor, includes a frame recorder. The frame recorder has a rotatable recording medium, first and second transducer means for recording and playing back video frames in recording tracks on the recording medium, and means for rotating the medium at the standard frame rate such that a video frame is recorded in each of the recording tracks. A field store is responsive to the recorder for storing a field of video information replayed from the recorder. A switch is connected to a field store and to the recorder for providing at the switch output video information from the field store or the recorder in response to a delay field signal.
