Abstract: Disclosed is a metallic transporting appliance, such as a flat pallet, a skid or a box pallet, designed in such a way that a thin metal plate is used entirely for the former two and for the side wall of the box pallet and the thin metal plate is subjected to special burring so as to have a sufficient durability, thereby contributing to the reduction of the amount of wood for conventionally popular wooden pallets in order to preserve natural resources. The metallic transporting appliance comprises a main plate (1) made from a thin metal plate having plural pairs of bores (2, 2) each formed at a predetermined interval (L) therebetween in a flat surface thereof, with a slit (3) formed between each pair of bores (2, 2) to couple the bore pair. The main plate (1) has a plurality of elongated hole portions (4) each having a bottom hole (6) with a flange (5) provided by burring those portions where the bore pairs are coupled with the associated slits. This main plate is adapted for the deck board of a skid. In the above metallic transporting appliance, lengthwise extending portions (1₁) of the main plate are bent downward and then bent inward toward each other with a predetermined thickness, both end portions (1₂, 1₂)) are joined at a center portion, and the flanges (5) of the elongated hole portions are welded to the extending portion by spot welding. This main plate is adapted for the deck board of a flat pallet or the side plate (12) of a box pallet.

Abstract: A virtual control apparatus emulates a video mixer through a computer (600, 360). The computer (600) can receive data and command information from its own command input means (610). The data and command information are mapped into data in a format recognisable by a CPU (630) within the computer. The resulting data and command information are stored in a memory (640) of the computer (600) and/or transferred to the video mixer (660, 300) for immediate video manipulation. Data transfer between the video mixer (660) and the computer (600) is implemented through a video communication tool (650, 10), which establishes a protocol of communication between the computer and the video mixer. Edit decisions from the video mixer can be transferred to and saved in the computer memory (640) for subsequent use. In the video communication tool (10) provided between the video mixer (300) and the computer (360), when serial data and control signals are transferred from the video mixer to the computer the serial data are converted into parallel data through a state machine and control logic unit (320), upon the beginning of a new frame. The parallel data are transferred to a FIFO (340). Upon the end of the frame the FIFO (340) is ported to the computer (360). When parallel data and control signals are transferred from the computer (360) to the video mixer (300), parallel data are stored in a FIFO (380). Upon an appropriate control signal from the state machine and control logic unit (320), parallel data are converted (370) into serial data. The serial data are clocked to the video mixer (300) on the rising edge of the clock signal.

wherein R 3  signifies an alkyl radical of 1 to 5 carbon atoms and R 1 =R 2 =methylene bridge from compounds of formula I
       
     In said patent, compounds of formula I are prepared by a three-step synthesis (Scheme 1) involving:
     a. nitration of 1,2-methylenedioxybenzene (MDB) (3a) to produce the nitro compound (4a) ;   b. subsequent reduction of 4a with hydrogen and a suitable catalyst (e.g. palladium on carbon) to produce 3,4-methylenedioxyaniline (MDA) (2b); and   c. alkylation of 2b to Produce N-alkyl MDA (I, R 3 =alkyl).   
     The following scheme illustrates the known synthesis of N-alkyl MDA.

Filed: 1991-05-27
Abstract: A distance sensing system (10) includes an ultrasonic transducer (XM1), a transceiver (12) and a microcontroller-based signal processing unit (14). The transducer (12) periodically generates and directs towards the terrain a dual frequency ultrasonic signal. Echo signals from the ground and/or any intervening crop or trash are reflected back to the transducer (12) and are processed. The system generates amplified and filtered echo envelope signals. Leading and trailing edge times are determined as the times the echo signals cross a threshold value which is a certain proportion of a maximum echo amplitude value. A near distance value is derived from the leading edge time of the first echo which exceeds a minimum amplitude. A far distance value is determined as the trailing edge time of the last echo signal which has an amplitude which exceeds a certain value. Multiple echo time and amplitude values are derived from the maximum amplitude echo. These values are used to prevent echoes which occur after the multiple echo time with less than a certain amplitude from being used in the determination of the far distance value. This far distance value represents the distance to ground and weaker, earlier echoes from trash or crop and later, multiple echoes may be ignored.
