Abstract: For a compatible color television system suitable for high and low definition on display, a MAC-system is taken as an example. Herein use is made of a digitally assisted DATV. To effect a bandwidth reduction encoding and bandwidth reduction decoding, use is made, in addition to the MAC-coding and MAC-decoding, of at least three picture signal channels (PC) each having a different picture signal refresh period equal to, for example, 80, 40 and 20 ms which are coupled via a time-division multiplex circuit (MUX). For with the diversity of picture signal sources, it was found that distinguishing during the picture signal processing between a film mode (SW1, T40) and a non-film mode (SW1, T20) results in a significantly improved high-definition picture resolution. This distinction is expressed at the DATV by one information bit (FM min ). During the non-film mode (SW1, T20) three Y-luminance channels (PC11, PC13 and PC12) of 80, 40 and 20 ms and two U and V-chrominance channels (PC21 and PC22) of 80 and 20 ms are operative. During the film mode (SW11, T40) the Y-channels (PC11 and PC13) and the U and V-channels (PC21 and PC23) of 80 and 40 ms are only operative. <IMAGE>

Abstract: A device for conducting the electric current from the cathode of a hooded, transverse electrolytic cell to the anode of a neighboring cell via cathodically polarized carbon blocks in the pot of a cell, cathode bars and individual conductor bars wherein the current from each cathode bar is passed under a cell to a compensating conductor bar which runs around the neighboring cell. This compensating conductor bar is connected to each anode of the cell it runs around via a flexible conductor strip. Each anode is provided on its uppermost side with a yoke which is inserted and firmly secured in place, together with the conductor strip, in a notch or recess provided in a device for holding the anode in place. The anode holding device remains in place during anode changes and can be adjusted vertically by means of a motor or the like as a function of the voltage or the desired interpolar distance between anode and cathode.

Abstract: A constant motion pipe swivel joint having a greatly improved useful life without leakage of fluid from the joint. The swivel joint includes a plurality of sealing discs rotatably positioned between an outer joint member and an inner joint member. One side of each disc is coated with a material having a low coefficient of friction and the other side of each disc is bonded to a layer of elastomeric material such as rubber. The discs are pressed together by the inner and outer members to provide a seal which prevents leakage of fluid from the joint. The rubber stretches to allow small degrees of rotation of the joint without any slippage of one disc over another, and the surfaces of the discs are free to slip over each other to allow a large amount of rotation of the outer joint member relative to the inner joint member.

Title: Call control system in atm switch
Inventor: KAKUMA SATOSHI
IPC: H04L12/911
Filed: 1990-08-06
Granted: 1995-02-07
Abstract: Abstract of the Disclosure Disclosed is a call control method for use with an ATM switch for integrating and switching various types of information which differ in traffic characteristics, such as voice, data and motion images, using an asynchronous transmission mode (ATM).          When a call is made to the ATM switch, it is accepted only when it is possible to set a path that can guarantee the service requested by the call.  When a call is made to the ATM switch, a load representing how much of the capacity of input links and output links of a self-routing module (SRM) constituting the ATM switch is obtained from the average value and peak value of the bit rate of the call.  The load is added to each of current loads of the input and output links and buffers of the self-routing module which form a path in the ATM switch.  A determination is made as to whether or not the result of the addition exceeds the maximum load of each of the input and output links and buffers.  On determination that the maximum value is not exceeded, the call is accepted.

Title: Integrated optics chip and method of connecting optical fiber thereto
Inventor: CHANG CHIN-LUNG
IPC: G02B6/30
Filed: 1990-08-16
Granted: 1994-12-27
Abstract: An integrated optics chip eliminates problems caused by polarization cross coupling in fiber optic rotation sensors without requiring time consuming and expensive alignment of the axes of the optical fiber sensing coil and the optical waveguides formed in the integrated optics chip. A substrate formed of an optically active material has slots formed therein for mounting optical fibers to the substrate. An optical waveguide is formed in the integrated optics chip to guide optical signals along a selected axis of propagation such that an end wall of the slot includes an end surface of the optical waveguide The end surface of the optical waveguide is formed to make an angle with the direction of propagation of light in the optical waveguide to reduce the amount of light reflected at the end surface of the optical waveguide. The angle of the end of the optical waveguide is formed such that light reflected at the interface back into the optical fiber impinges on the core/cladding boundary at an angle that permits refraction from the core into the cladding. The angle of the end of the optical waveguide preferably is in the range of 5° to 25°.

Title: Fiber optic sagnac interferometer with digital phase ramp resetting for measurement of rate of rotation
Inventor: GROELLMANN PETER
IPC: G01C19/72
Filed: 1990-10-04
Granted: 1995-11-21
Abstract: In order to avoid a lock-in effect, and in order to avoid scale factor nonlinearities, particularly in the case of low rates  of  rotation,  it  is  proposed  for  a  fiber  optic interferometer rate-of-rotation sensor which is reset by phase ramp via a digital control circuit to undertake the reversal, necessary to obtain the scale factor error information, of a reciprocal, alternating phase shift not as a function of the angle  of  rotation,  but  with  a fixed  timing,  which  can advantageously be synchronized with the gyroscope modulation frequency.  The advantage of the invention is that even in the case of low rates of rotation, in particular, a scale factor error correction is possible and a lock-in effect, caused by variations in bias in the case of the modulation deviation reversal, is avoided.
