Abstract: The BASEBAND VIDEO/AUDIO/DATA TRANSCEIVER invention simultaneously transmits and receives baseband video signals, audio signals, and associated digital data and control signals within a single continuous signal over a single physical transmission line. The device is a single cohesive module, best embodied as an integrated circuit. The audio signals are sampled, and subsequently reconstructed. Audio samples and digital signals are multiplexed, then fed to a multirate elastic buffer. The multiplexed signals are extracted from the elastic buffer coincidentally with the video signal horizontal synchronization pulses and applied to these same pulses, then placed on a channel having a similar transceiver at the other end. The transceiver invention separates the received signals from the transmission line by canceling out its own transmitted signal. The received audio and digital data bursts are culled and reshaped.

Abstract: There is provided improvements in magnetic recording head arrangements, such as may employ multiplexing, which provide substantially higher speeds of recording and require fewer components. The recording head is comprised of a compact, four-layer laminate structure mountable on a supporting substrate, in which the entire array of recording elements forms a flexible, uniquely arranged first layer, the return paths of the recording elements comprise a flexible second layer which has the dual utility of substantially reducing the recording element circuit inductance, the third layer is a rigid printed circuit board structure providing a mount for the blocking diodes and the conductive paths of the associated multiplexing scheme, and the fourth layer is a ground plane located between the first and third layers and insulated therefrom for further reducing the inductance associated to the circuitry of the first layer and for substantially minimizing the circuit inductance of the third layer.

Abstract: A programmable industrial sewing machine adapted to learn and store, in Automatic Learn or Key Learn Modes of operation, a series of sewing machine operations for later automatic duplication. In both modes of operation provision is made for an operator to select the number of initial and final locking stitches prior to commencing stitching operations. Operator actuated controls, such as knee shift device and foot treadle, operate identically in both Learn Modes of operation and as they would operate in a normal manual industrial sewing machine. In the Automatic Learn Mode of operation, a record is compiled in segments, consisting each of a stitch count, a pivot delay time, and a speed copy. In appropriate circumstance, the pivot delay time may be zero.

Abstract: The carriage of a home knitting machine is provided with a reader operable independently of any movement of the carriage of the machine for reading out patterning instructions on a programmed card prior to knitting, an electronic memory for storing the signals read from the card, and means for recalling the stored signals from the memory in synchronization with movement of the carriage during knitting and for causing the operation of needle selectors on the carriage in accordance with the recalled signals to provide for the formation in a fabric of a pattern defined on the card.
