Abstract: A laminated film or sheet comprises poly-4-methyl-1-pentene laminated on a paper layer. By using poly-4-methyl-1-­pentene having a low melting point, formation of cracks and other defects in the resin layer is prevented and the oil and fat impermeability is improved. If an intermediate layer of a specific polymer is formed in addition to the poly-4-methyl-1-pentene layer, the oil and fat impermeability is further improved. A box-shaped vessel (carton) and a release paper for an artificial leather can be prepared from this laminated film or sheet.

Abstract: A short dwell coater apparatus (10A) is disclosed for coating a web (WA) with a coating material, the web moving contiguously with a rotating backing roll (26A). The appa­ratus (10A) includes a housing (12A) which is disposed on the opposite side of the web relative to the backing roll (26A). The housing defines a coating chamber (14A) having an upstream and a downstream end (18A,20A). The chamber is connected to a pressurized source (16A) of coating ma­terial. The chamber is exposed to the web such that the web supported by the backing roll (26A) is coated with the coating material during passage of the web past the coating chamber (14A). The upstream and downstream ends (18A,20A) of the coating chamber define first and second weirs (22A,28) respectively. Each of the weirs (22A,28) extend in a cross-machine direction such that the coating chamber (14A) is bounded by the weirs and the web moving between the weirs. The first and second weirs (22A,28) define respecti­vely first and second overflow gaps (30,32). The arrange­ment is such that during use of the apparatus (10A), when the web moves past the coating chamber, coating material is coated onto the web (WA) while excess coating material overflows through the first and second gaps (30,32) for recirculating through the coating chamber. A resilient blade (24A) is disposed downstream relative to the second weir. The blade (24A) cooperates with the coating material coated onto the web such that the pressure exerted by the coating material on the blade is less than the pressure of the coating material within the coating chamber, so that mottling and streaking of the resultant web (WA) is inhi­bited while maintaining minimum pressure on the blade (24A).

Abstract: This invention relates to a controller for control of transmission means in a signalling system. The controller comprising a keyboard (12), a data base (14), first and second translation means (18, 19) and transmission means (21 or 22). The data base has a structure which enables uniform design and operation for virtually any signalling scheme, e.g. MDC-1200, MDC-1600, Select 5, Quick Call 1, Quick Call 2, DTMF, Digital Dial, Prism, ZVEI Binary, POCSAG, Single Tone etc. The data base has a plurality of buffers, each having a first data field (30) for defining a signalling format, a second data field (31) for identifying a party or parties to be called, a third data field (32) for defining a physical communications path and a fourth data field (33, 34) for defining an operation code and optional data. 
     Upon initiation of a transmit command, a data buffer sets up a call. For that call the signalling format controls the first translation means (18) for defining the translation of data input at the keyboard into data in the second and fourth data fields and the signalling format for its transmission. The communications path data controls the transmission means set-up, and the format and operations code control the second translation means (19) for translation of the operations code and the optional data into the transmitted data package.

Abstract: A cable television measurement system uses a modified spectrum analyzer for determining both carrier-to-noise and triple beat ratios for a cable television (CATV) system. The modified spectrum analyzer is triggered for single sweep during the vertical interval of a selected channel, and the noise amplitude, peak sync tip amplitude and frequency of the channel are determined. The carrier-to-noise ratio is determined from the noise amplitude and the peak sync tip amplitude and the ratio and frequency are displayed. For triple beat ratio measurements a headerd unit coupled between a television signal source and a combiner in the CATV headend prior to distribution offsets a selected channel by a predetermined frequency for a specified number of lines in the vertical interval. The modified spectrum analyzer measures the peak sync tip amplitude and a triple beat amplitude at the end of the specified number of lines. The triple beat ratio is determined from the triple beat amplitude and the peak sync tip amplitude and displayed.

Abstract: An engine controller controls the ignition timing in response to engine operating conditions - here especially on determination of engine idle condition. Engine idle condition is determined after a delay time after detection of throttle fully closed position. The delay time is determined in response to operating conditions of the engine - here especially on an elapsed period, since start-up of the engine. The controller prevents the engine from causing a tapping noise during start-up, while the engine is not enough lubricated yet by fast determination of idle condition and thus reducing the ignition timing to the retard side thus removing torque from the engine.
