Abstract: ABSTRACT OF THE DISCLOSURE           Sudden accidental unintended movement of an automatic transmission into reverse with the engine running is prevented by modifying the usual control rod to provide a cam surface so positioned thereon that as the control rod is moved a pre-determined distance from reverse towards park a spring loaded member engages the cam surface and both restrains unintended movement of the control rod back to reverse and positively drives the control rod into its full park position as soon as the parking pawl aligns with a space between teeth of a parking gear.  The invention may be assembled as original equipment in conventional transmissions or added to existing transmissions with little or no modification in design.

Abstract: A B S T R A C T     Contiguous metal plates are welded together without special edge preparation or beveling e.g. of cut edges from one side using a focused high intensity laser beam  . To ensure maintenance of welding conditions even when the plate edges are spaced apart by cutting imperfections or the like a wire    is fed to, or near, the beam focus    to intercept the beam and give rise to a plasma. This plasma is kept in place by gas supply means  , the gas supply through dueling        of which (a) prevents plasma building up above the weld zone (which would decrease the beam intensity at the weld) but (b) holds some plasma in the region of the beam impingement on the  wire so as to allow energy transfer to the adjacent walls.       Butt welds or T welds can be made in this way, even in plate material, in a single pass from one side. The technique thus permits the arrangement of work stations on a production line to be simplified and rationalized when making up multiweld repeat structural units e.g. in shipbuilding.

Abstract: SYSTEM, METHOD, AND STATION INTERFACE ARRANGEMENT FOR PLAYING VIDEO GAMES OVER TELEPHONE NETWORKS Abstract A system, method and station interface arrangement which permits video games to be played over a telephone network is disclosed. Communications delay between the games can be mitigated by transmitting local player position data to a remote game, the position data being detected at a local game during a current "generation" but the position data not being used by the local and remote games until the next generation and the transmission occurring during the time interval in which the current generation is being run at the local game. The position data can be encoded so that errors, e.g. transmission errors, may be detected. Detected errors may be corrected by retransmitting the priorly transmitted local position data. In addition, the games may be synchronized or resynchronized by transmitting a frame count along with the position data. The frame count may identify by order of succession the respective local and remote position data so that the games obtain and remain synchronized.

Abstract: A TECHNIQUE FOR SYNCHRONOUS NEAR-INSTANTANEOUS CODING            Abstract The present invention relates to a near instantaneous companding coder wherein the peak a-c amplitude of an input signal is measured over a block of K samples.  Each of the K samples is coded into an n-bit quantized sample code word based on a step size quantizing control signal determined from the measured peak a-c amplitude.  The step size quantizing control signal, and other overhead information such as parity, sync, etc., are formed into a K-bit overhead word and transmitted serially by adding a separate bit of K-bit overhead word to each of the corresponding K n-bit quantized sample code words associated with an immediately prior block of K sample code words.  At the remote decoder, the received K-bit overhead information word is stored and used to decode the next subsequent block of K received n-bit quantized sample code words.
