Abstract: An apparatus for butt splicing webs is provided, wherein the splicing accuracy can be improved and the cost can be decreased since the webs can be spliced without an accumulator and the splicing mechanism can be simplified. 
     When the remainder length of the old roll (28) becomes short, the splicing unit (36) is moved to be abutted to the outer peripheral surface of the new roll (30) and stopped and the new roll (30) is rotated previously at the same speed as the conveying speed of the old roll (28). Then, when the forward end portion (32) of the rotating new roll (30) is detected by the sensor (68) while splicing webs, the cutting drum (42), the cutting-splicing drum (44) and the splicing drum (46) are started to run based on the detected signals and are rotated at the same speed as the conveying speed of the web, and then the forward end portion (32) is stuck and drawn out by the suction pad (42C) of the cutting drum (42), and the webs are cut and spliced in the state that the tail end of the old roll (28) and the forward end of the new roll (30) are held by the respective drums (42), (44) and (46). And, when the splicing of the webs is completed, the splicing unit (36) is retracted from the outer peripheral surface of the new roll and returns to the former position. Therefore, the webs can be spliced without decreasing the rewinding speed of the old roll (28) and the splicing mechanism can be simplified.

Abstract: It is known that perturbations caused by scattered-radiation in an x-ray image can be partially avoided by employing a scattered-radiation grid. A device for further improvement of an x-ray image, in that real-time correction of scattered-radiation effects is achieved, is provided according to the invention. 
     Behind x-ray absorbing parts of the scattered-radiation grid only scattered-radiation appears, whereas both scattered-radiation and primary radiation appear behind transparent channels of the scattered-radiation grid. The scattered-radiation grid gives rise to a high-frequency intensity modulation in the x-ray image. From the high-frequency component of the corresponding video signal produced by the x-ray detector, selection signals are generated by a double pulse generator for distinguishing signal amplitudes of the video signal, corresponding to intensities behind absorbing parts and transparent parts , respectively, of the scattered-radiation grid. The selection signals are supplied to a synchronous detector to split the video signal from the x-ray detector into separated video signals corresponding to scattered-radiation and primary radiation and to scattered-radiation only, respectively. A video signal corresponding to a corrected image is obtained by subtraction of the separated video signals.

Abstract: Complications of timing recovery in an ATM receiver (200) are overcome by employing a first phase lock loop (208) including a phase comparator (210), filter (211), voltage controlled oscillator (212) and output counter (214) to lock to systems clock reference (SCR) values which are asynchronously received from a remote ATM transmitter. The SCR values represent the instantaneous values of a system timing clock (STC) at the instant of transmission of the asynchronous SCR values. In the receiver, the output counter (214) is first set to the value of the initial received SCR value so that the derived STC is available for decoding data cells in the initial received packets. Then. so-called Presentation/Decode Time Stamps (PTS/DTS) included in the audio and video data are advantageously employed in conjunction with STC to display properly the received data. Underflow of the receiver data buffers (202,205) is alleviated by the addition of a "jitter-delay (D j )" value which causes an extra accumulation of data in the data buffers prior to decoding. Dynamic tracking of the jitter-delay of the channel is obtained (217) by monitoring the fullness of the data buffers and controllably adjusting the jitter-delay, accordingly. The stability of the video decoder (204) timing is enhanced by employing an additional phase locked loop in a video display control (203) which is supplied with a timing error signal. The additional phase locked loop includes a switch, filter, clipper and voltage controlled oscillator (VCO). The switch is enabled in response to output pulses from the VCO to supply the instantaneous error signal input to the filter for each so-called video presentation unit. The VCO has a very stable center frquency in which variation is limited by clipping an input control voltage to some small voltage range. Output pulses from the VCO are employed to enable decoding of the presentation units. Faster synchronization is provided at start-up by increasing, via control of the clipper, the allowable voltage range of the VCO.

Abstract: A sine wave signal generated in synchronism with a pulse signal determining a frequency of vibrations and noises generated by a vibration/noise source is input to a W filter and a C filter. The C filter selects filter coefficients dependent on the rotational speed of an engine, and generates a transfer characteristic-dependent reference signal R dependent on a transfer characteristic of a vibration/noise-transmitting transmitting path, based on the filter coefficients. Alternatively, a divisional signal is prepared by dividing a repetition period of vibrations and noises by a predetermined number, and values of a sine wave generated in synchronism with occurrence of said divisional signal is delivered to a W filter, while the transfer characteristic-dependent reference signal is delivered from the C filter storing data of the transfer characteristic identified in advance to the W filter. Alternatively, a sine wave signal and a delayed sine wave signal delayed by a quarter of a repetition period of the sine wave relative to the sine wave, as well as phase and amplitude-related information of the transfer characteristic of the path are generated and delivered in synchronism with generation of the divisional signal. These sine wave signals and the transfer characteristic-dependent reference signal (phase and amplitude-related information) are used to actively control the vibrations and noises.

Abstract: The amount of Group-V element included in a melt 6 has the close relationship with the oxygen concentration of the melt 6. This relationship is utilized for controlling the oxygen concentration of a single crystal 8 at a high level. The content of Group-V element is calculated from the weight of the melt 6 gauged by a gravimeter 11 and compared with a preset value in a control unit 12. When the calculated content is smaller than the preset value, the control signal to additionally supply Group-V element to the melt 6 is outputted from the control unit 12 to a feeder 14. When the calculated content is larger than the preset value, the control signal to supply a raw material to the melt 6 is outputted to another feeder 13.

Abstract: Plasticized safety document provided with a passport photo, such as admission passes, bank passes, credit cards, should be fraud proof as good as possible. According to the invention, a passport photo having knurled or toothed edges is used. Such a safety document can be obtained e.g. by applying a passport photo onto a document of cardboard or plastic provided with identification particulars, and subsequently cutting out the passport photo with a passport photo cutter, provided with a cutting window having knurled edges, and inserting the knurled passport photo (2') with knurled edge (3'), cut to the appropriate size, into the likewise knurled opening (4') formed in the document by cutting-out. This assembly is laminated on two sides with polyester sheet (5) provided with an adhesive layer by means of hot-pressing. Thus, one obtains a safety document that meets the highest requirements of protection against fraud, and from which the passport photo can not be removed undamaged on opening the lamination. Furthermore, it is extremely difficult to insert a new passport photo, because it should have the appropriate knurl pattern.

Abstract: A token ring local area network includes workstations running both conventional data and multimedia applications. The latter, which generally require a minimum throughput in order to be viable, can be split into two further categories: those which cannot tolerate excessive latency (end to end delay), typically interactive applications such as voice communications, and those which are less sensitive to latency, typically playback operations. the network recognises three priority levels: (1) for latency-sensitive multimedia applications, (2) for latency-insensitive multimedia applications, and (3) conventional applications. All multimedia applications prior to commencement of any communications over the LAN must request an allocation of throughput from a LAN segment resource manager (LSRM), which will only be awarded if there is currently sufficient available throughput on the LAN to support the attended communication. Furthermore, first priority level applications are also given a maximum token holding time, thereby ensuring rapid circulation of the token, and controlling latency.

Abstract: A microwave crosspoint blocking switch matrix and assembly (1) employing multilayer stripline and pin diode switching elements is employed to selectively electrically couple and decouple input transmission lines (2) to output transmission lines (4) without severance of the transmission lines and insertion of a series switch. The microwave crosspoint blocking switch matrix assembly employs pin diode arrays (6) coupled to input and output transmission lines at respective crosspoints (8). In order to route a signal from a specific input line to a selected output line, the pin diode array at the input/output transmission line crosspoint is activated and each transmission line is shorted at points one-quarter wavelength distant from the crosspoint to reflect, ideally, an infinite impedance at the interconnection point. Therefore, a desired signal cannot propagate in any direction except from the selected input line to the desired output line.
