Patent EP-0024295-A1 (EP)
Inventor: THOMAS JR JAMES W
IPC: H04L25/49
Filed: 1980-07-11
Abstract: Incoming diphase signals E which have base bit intervals delineated by spaced clocking signals with data information occurring between the clocking signals are fed to a four bit shift register (10) which in cooperation with an exclusive OR-gate (14) generates a pulse D for each diphase signal E transition. Upon receipt of a preamble comprising four diphase signal transitions, a shift register (16) provides a signal MSR which initiates the decoding of the following data information. A counter (24) stores counts related to the time intervals between each two successive clocking signals and counters (26 and 28) store a count related to an immediately subsequent time period which is three-fourths of the time interval. The occurrence of data information is sensed by a logic array (20) during successive time periods and a nonreturn to zero mark-space output signal K is stored in a flip-flop (22). The logic array (20) continually updates the counts stored by the counters (24, 26-28).

Abstract: The composition described herein is a hydrogenated polymer derived from a polybutadiene having 85-100%, preferably 95-100% 1,2-structure. The hydrogenated product is an elastomeric material which is oxidation-resistant and stable against ozone. Moreover, since the original high vinyl polymer may be made by a method which permits control of the molecular weight, the molecular weight of the ultimate hydrogenated products is also controllable. The control of molecular weight and microstructure give highly desirable properties in the ultimate elastomeric product, and also control of tacticity and crystallinity.

Abstract: A method for the production of alloyed steel products having substantially no ferrite matrix phase and having Md and Ms conversion temperatures (as herein defined) such that plastic deformation may cause phase transformation, comprises effecting plastic deformation partly at a cryogenic temperature of from 0°C to the Ms conversion temperature (as herein defined) and partly at a low temperature of from 0°C to the recrystallisation temperature, the plastic deformation at said cryogenic temperature being effected prior to plastic deformation at said low temperature. 
     The method enables heat transfer and cooling problems inherent in known methods to be overcome and may also be employed to produce alloyed steel products having improved properties e.g. tenacity, creep resistance and/or fatigue strength over similar products produced according to known methods.

Abstract: An optical waveguide device (140) is disclosed, which includes an optical waveguide member (11) for receiving a thin beam (Lin) of polarized light, modifying the beam, and emitting a differently polarized beam (Lout) from an output surface. The beam is modulated within the waveguide member (11) by the application of an electric field or a magnetic field. For a given supply voltage (V, 13), the greatest modulating effect is obtained with long and very thin waveguide members. In the device according to the invention, the top and bottom surfaces of the waveguide member (11) are coated with at least one phase-matching layer (141,141'). The thicknesses and refractive indices of the coatings are calculated so as to reduce substantially to zero the difference between the phase shifts experienced on reflection at each surface by P polarized and S polarized components of the light beam.
