Abstract: A speed measuring device for measuring the speed of a water craft is disclosed which includes first and second transducers (T1, T2) mountable on the water craft below the water line thereof so as to face one another across an acoustic path (figure 2). An acoustic pulse transmission circuit (140-240) energises a selected transducer for transmission of an acoustic signal along the acoustic path. A receiver circuit (270, 290, 350) for processing the acoustic signal as received at the nonselected transducer and for determining the arrival time of the acoustic signal is provided with the transmitter and receiver circuits being under the control of a micro processor and associated circuitory (130-140). The micro processor also changes the selection of the transducer means so as to change the direction of the transmission so that transmit times in both directions may be obtained, the difference between these transmit times being related to the speed of the craft throught the water. 
     In order to improve accuracy the micro processor controls the transmission circuitry to send a plurality of pulses in one direction and then the other, with the arrival of a subsequent pulse triggering the   transmission of the next and means are provided for adjusting the number of pulses generated in each direction independence upon sea conditions. An automatic gain control circuit is also disclosed for automatically adjusting the gain of the received signal.

Abstract: A dual containment channel for fluids comprises a plurality of channel segments arranged end-to-end to define a channel run of a predetermined desired length. Each channel segment comprises two spaced-apart opposing channel segment side walls connected by an integrally-formed bottom wall to define a generally U-shaped structure having a top opening and a void therein for carrying afluid and a cover for being positioned between and supported by the side walls to enclose the open top of the channel run and retain any fluid within the channel. The channel run thereby serves as an outer containment channel. Supporting means are positioned in spaced-apart relation within the channel along its predetermined length for supporting at least one elongate, closed wall, fluid carrying conduit therein. Any fluid leaking from the conduit is contained within the outer containment channel for ease of removal. Any leaks in or damage to the conduit can be easily located and repaired by removing the cover. Any leaks in or damage to the outer containment channel can be repaired by replacing only that channel segment or segments which are actually damaged.

Abstract: The demodulation circuit includes a Schmitt trigger circuit(2), first and second monostable multivibrators (31, 32), a quartz oscillator (5), first and second low-pass filters (4, 6), and a comparator (7). The Schmitt trigger circuit (2) converts a modulated signal modulated by data into a pulse signal. The first monostable multivibrator (31) converts an output from the Schmitt trigger circuit (2) into a PPM signal. The quartz oscillator (5) oscillates at the same frequency as the center frequency of the modulated signal. The second monostable multivibrator (32) is formed on the same chip as the first monostable multivibrator (31) and responsive to an output signal from the quartz oscillator (5). The second monostable multivibrator (32) generates a signal comprising a pulse train having the same pulse width as that of the PPM signal output from the first monostable multivibrator (31) and a constant pulse separation. The first low-pass filter (4) receives an output from the first monostable multivibrator (31). The second low-pass filter (6) receives an output from the second monostable multivibrator (32). The comparator (7) compares an output signal from the first low-pass filter (4) with an output signal from the second low-pass filter (6) as a threshold level, and obtains modulation data.

Abstract: The control unit (40) comprises a program memory (41) and a random- access memory (42). The program memory exhibits for each measurement input (1-8) a separate memory area (1'-8') into which the analog measuring range associated with the respective measurement input and the type of the analog measurement quantity is programmed. The memory area (1'-8') is programmed by the user before the measuring event as a result of which the semiconductor switches (11-28) are correspondingly activated for each measurement. 
<??>If the type of analog measurement quantity is changed or the analog measuring range is changed, only the memory content (1'-8') of the program memory (41) has to be changed in accordance with the new measurement values. This does not require any hardware modification of the measurement inputs.

Abstract: A method and apparatus for presenting a serial succession of cut sheet portions to a work station. The sheet portions are cut from a continuous webbing which is processed by a cutting station and a web-breaking station. The cutting station partially severs the web downstream of its leading free end so as to define a first sheet portion between that free end and the point of cutting, with the first sheet portion connected to the web by one or more tab connectors. The webbing is then advanced downstream to the tab-breaking station where the tabs are broken to free the first sheet portion for independent movement further downstream. A vacuum belt engages the webbing, and particularly the downstream edge adjacent the partial severing, with a vacuum belt. The vacuum belt engages the webbing by bridging the partially-severed cut portion, so as not to interfere with the downstream tab-breaking apparatus. A continuous control over the cut sheet portions is provided prior to the breaking of the tab portion, and continues to the final delivery of the cut sheets.

Abstract: The interruption of an alternating pulse train (for example that produced by an open collector transistor driven on and off by a fan rotation sensor) is detected by a circuit comprising: 
an input node (13) to receive the pulse train; 
voltage conversion means (15, 18, 22, 26 and 28) connected to the input node for converting the pulses of the pulse train to a steady state DC signal level higher than the voltage level of the alternating pulses; and 
comparator means (36) connected to the conversion means for comparing the DC signal level with a reference voltage, 
the comparator means producing an output when the DC level of the conversion means falls below the reference voltage level as a result of the absence of pulses from the pulse train regardless of the state in which the pulse train is interrupted. 
     The circuit design ensures that the steady state voltage level decays to an under voltage value when the pulse train stops regardless of whether the fan output stops in a high or low state.

Abstract: Apparatus for detecting the speed with which a light beam emitted by an optical head accesses a target record track on an optical disc in which record track traverse data indicating track number are recorded previously. The traverse data is read and traverse data signals indicative of the scanning position of the light beam are produced. Deviations in the traverse data signals obtained at predetermined time intervals are detected to form upper order data bits representing access speed. At the same time, tracking error data signals proportionate to the deviation of the light beam from a record track on the disc are produced and a deviation in the tracking error data signals is detected to form the lower data bits of the access speed.
