Abstract: A control system especially but not exclusively for use downhole in a well bore during drill stem testing, includes first means (38) for producing a first response to a changing stimulus (eg. well bore pressure changing at a varying rate); second means (58) for producing a second response to the stimulus, which response is initially masked by the first response; and signal producing means (6) arranged to produce a signal when the second response exceeds the first response. In one embodiment, two components (38,58) are moved in different directions, but in a net first direction, until the rate of change of the pressure is sufficiently low (e.g. near steady state), at which time the rates of movement of the two components produce net movement in a second direction which initiates a control valve (6) to produce a signal.

Abstract: The invention relates to a device for extruding rubber blends and rubber-like materials, consisting of a screw extruder and an injection head shaping the extrudate in a strand-shaped manner. The object of the invention is to provide an extruder/gear pump combination suitable for processing rubber blends. The invention consists in that in the device for extruding rubber materials a gear pump is disposed between the extruder and the injection head, and that the screw tip extends into the housing of the gear pump or up to a plane extending in a parallel manner to the axes of the gears of equal diameter or tangentially to the gear of larger diameter or beyond this plane into the gap between the two gears. For processing extremely sensitive rubber blends, it is expedient if the length of the extruder screw is dimensioned solely for an adequate plastication of the rubber materials to be extruded and if a two-screw extruder, the screws of which rotate in mutually opposite directions and the flights of which intermesh, is connected to this single screw extruder to build up the extrusion pressure.

Abstract: The invention relates to a method for connecting at least one electrical winding (14, 16) to an iron core (12), especially of ignition coils, by means of an adhesive which can be cured by heat. It is proposed that the windings (14, 16) and core (12) be subjected to a high-frequency alternating field, in such a manner that the winding (14, 16) and the core (12) are heated. This results in the unit (10) of the winding formers (14, 16) and the core (12) being rapidly and uniformly heated, as a result of which mechanical stresses are avoided and better adhesion can be achieved. <IMAGE>

Abstract: The present invention form overlapping regions on the boundaries of neighbour image regions in a block copy image. In the method of the invention, region numbers are allocated to separate image regions in an original image, and overlapping regions or frame regions of a predetermined width are created on the boundaries of the neighbour image regions while alternately applying an eight-neighbour window and a four-neighbour window (S52 and S57). Each window includes a center pixel and neighbour pixels with a predetermined priority. Region numbers are allocated to the frame regions based on the region numbers of the center pixel and the neighbour pixels and on the priorities. The color of each frame region is determined according to a predetermined method, which depends on printing types such as offset printing and gravure printing. Color components of each frame region are determined according to the color of the target frame region and the color of another frame region neighbour to the target frame region across the boundary of the original image regions.

Abstract: A speaker driving device applies a constant voltage of a constant voltage source (3) a pair of voice coils (5) alternatively by switching the direction of applying the constant voltage based on a binary PDM signal. A AE modulator (2) produces the binary PDM signal by △∑ - modulating a digital audio signal from a digital low - pass filter (1). The constant volt - age is applied to a first voice coil in one direction and is applied to a second voice coil in the reverse direction by switching (4) the direction of applying the constant voltage. The first and second voice coils forms the pair of voice coils. This arrangement causes a current to flow through the first and second voice coils in opposite directions and a diaphragm of a speaker to be driven in two directions opposite to each other. As a result, the speaker is driven more efficiently. Moreover, since the switching of the di - rection of applying the constant voltage is performed by changing the connections between the constant voltage source and the pair of voice coils, a switch - ing circuit (4) with a simplified structure is used.

Abstract: Terephthalic acid is produced by oxidation of para xylene, purified in an aqueous phase and recovered by precipitating a purified product from the aqueous phase, the aqueous phase mother liquor is then cooled or evaporated to produce a further less pure precipitate and a second mother liquor and the less pure precipitate is returned to the reaction medium and/or the water of the second mother liquor is used to dissolve the crude solid and/or the second mother liquor is treated to recover water which is used to wash the precipitate recovered from the aqueous solution. The process produces better yields of terephthalic acid, reduces the use of water and reduces problems in the disposal of polluted waste water.

Abstract: A Tape Automated Bonding (TAB) process prepared Multi-Chip Module (MCM) having semiconductor dice embedded into the substrate (20) of the MCM through its top face. A heatsink (28), which in a preferred embodiment is a copper slug, is emplaced into the underside of the substrate so that the bottom surfaces of the dice engage the heatsink. A compliant, heat-conducting thermoplastic material is used to secure the dice to the heatsink and to maintain a good heat flow path. According to the present invention, the TAB formed component (22) has beam leads that do not require bending to facilitate assembly. Rather, the beam leads are trimmed to length, leaving straight outer beam leads that, after the die is installed in the substrate, extend parallel to and overlie the top face (26) of the substrate. The beam leads are thus positioned for convenient bonding to signal paths laid out on the top face of the substrate.

Abstract: A portion of a sufficiently thick insulating layer formed on a substrate is removed so that a recessed device region is formed and surrounded by masking wall portions left at both ends of the recessed device region. A first oxide superconducting thin film is deposited at angle of 30 to the substrate so as to ensure that a c-axis oriented oxide superconducting thin film grows in such a way that a portion of the recessed device region is masked by one of the masking wall portions so that no thin film grows over the masked portion of the recessed device region. Then, another oxide superconducting thin film is deposited at angle of -30 to the substrate so as to ensure that an a-axis oriented oxide superconducting thin film grows in such a way that another portion fo the recessed device region is masked by the other of the masking wall portions, so that no thin film grows over the masked portion, but the a-axis oriented oxide superconducting thin film is in contact with the c-axis oriented oxide superconducting thin film, with the result that a grain boundary functioning a weak link is formed between the a-axis oriented oxide superconducting, thin film and the c-axis oriented oxide superconducting thin film.

Abstract: A digital video editing apparatus in which the frame number information that is encoded in non-visible portions of frames in an analog video signal is utilized to ensure that there are no missing frames of corresponding digital video information. The frames of analog video information are digitized and stored in the editing apparatus using a two-pass procedure. In the first pass, as many analog video frames as possible are digitized and stored, and the frame numbers from the frames are utilized to form a list of missing frames. In the second pass, the missing frame list is utilized to reposition the analog video source and to read in the missing frames. If desired, a digital frame trap may be provided such that the contents of a temporary frame memory are frozen until computer processing apparatus has enough time permanently to store the trapped frame. Once a complete set of digital frames has been converted and stored, digital video editing may be undertaken, and the edited digital frames may be outputted in analog form.
