Patent ES-473132-A1 (ES)
Title: PCM codec using common d/a converter for encoding and decoding
IPC: H04B14/04
Filed: 1978-09-06
Abstract: A coder/decoder in a PCM communications system, employs a common digital-to-analog converter. In a basic sampling interval the incoming PCM signal is decoded at a decision level on one side of the desired reconstruction level then modified and again decoded at a different decision level on the other side of the desired level. The average of the two decoded signals then lies on the desired level giving a decoding characteristic having decision levels between those of the encoding characteristics. As used in a conventional PCM system, the two PCM samples differ by only one least significant bit. In a preferred embodiment, separate storage registers R1 R2 are used for encoding and decoding, plus a selector 262 for switching between the two registers during the decoding intervals. Thus, encoding may be effected during a substantial portion of the basic sampling cycle, being interrupted only to generate decoded samples. The invention is applicable to PCM systems generally, including compressed pulse code modulation systems.

Title: Railway freight wagon.
IPC: B61D17/04
Filed: 1984-02-29
Abstract: A freight car is constructed with an undercarriage having a flat cargo floor and with an upright fixed end wall at each end of the floor. A gantry in the form of an arch extends upwardly from the floor substantially centrally between the end walls and a hood support rail extends between the fixed end walls on each side of the floor. The space above the floor is covered by a hood which is of a length to extend between the gantry and one end wall and which includes a roof portion which overlies the gantry and the one end wall and side wall portions which extend downwardly from each side of the roof. The side wall portions carry rollers or casters which are engageable with the rail for supporting the hood for movement along the rail. The hood may be moved when it is in an open position along the rail for example to completely uncover the space between the gantry and one end wall. Two hoods are advantageously employed, each of which is movable along the rail when they are positioned in an opened position but only alternatively. When they are in a closed position an actuator lifts the side wall of the hood upwardly to move the casters off the rail and to move the side wall inwardly toward the edge of the floor into a closed position.
