Abstract: A semiconductor laser comprising spaced apart optical cavities (3, 5) which are mutually optically coupled through cleaved mirror surfaces at facing ends of the cavities. Each cavity is provided with electrode mean (7, 9) whereby the optical characteristics of the laser can be tuned to provide a high intensity, singlefrequency mode light output. The frequency of the output mode can be shifted in precise amounts allowing use of the device in a frequency shift keying communications system. Also, greater stability of the light output is obtained by means of a feedback system (Fig. 20) utilizing certain detected characteristics of the output light.

Abstract: In an encode method in which a binary data stream is divided into data words each of three bits. Each of the data words is encoded into a binary code word of 9 bits. In the method, a code word to be encoded is encoded in consideration of a code word preceding the code word and two code words succeeding the code word. Then, one of the first two code bits in each code word and two of the last five code bits in the preceeding code word are inverted according to a pattern of code bits «0» and «1» in both the code words. As a result, consecutive 5 to 19 code bits «0» are arrayed between two adjacent code bits «1» in the code word stream.

Abstract: An encoder/decoder for detecting and correcting a burst error of a cyclic code uses a two-way feedback shift register including a chain of pieces of flip flops and exclusive OR gates corresponding to generator polynomials. A received code word is provided to the two-way feedback shift register in a forward shift direction during a decoding mode, After inputting the received code word into the feedback shift register, if a syndrome is not equal to zero, the shifting direction of the feedback shift register is ehanged over, so that the shifting of the contents of the flip flops is repeated until a zero tester detects that outputs of selected (ℓ-m) pieces of the flip flops become all-zero. When the zero tester detects the all-zero, the contents of remained m pieces of the flip flops are provided as an error pattern of the received code word.

Abstract: A valveless, variable displacement, reversible, fixed dead volume metering pump formed with a cylinder (26) having ports (25, 27) through which to pump fluid. A rotatable piston (24) is in the cylinder (26) with a duct thereon communicable with the ports (25, 27) to transfer fluid to and from the cylinder (26). A drive coupling (12, 14) is provided for the piston. The piston reciprocates in the cylinder while rotating in a timed relation with respect to the ports (25, 27) and the timed relationship is reversible. The relative angularity between the axis of the piston and the axis of the drive coupling (12, 14) is reversible to obtain reversal of fluid flow with the degree of relative angularity determining the volume of luid being pumped. A substantially constant dead-volume is maintained throughout the range of relative angularity between the axes through the use of a pair of floating swivel axes (86, 87) with a cam to restrict one or both of the axes and free the other depending upon direction of relative angular movement of the axis of the piston (24) with respect to the axis of the drive coupling (12, 14).

Abstract: Gas mixtures are purified, especially for removal of gases which pollute the environment, such as nitrogen oxides, carbon monoxide, hydrocarbons and/or sulphur oxides from exhaust gases and flue gases, in the liquid phase by means of catalysts. According to the invention, substantial activation of the catalysts used in such processes is achieved by bringing the gases into intensive phase contact with a contact fluid containing a catalyst suspended or dissolved therein, by forming a foam from the gases and the contact fluid and allowing the reaction to proceed in the foam phase thus formed. In this way, it is possible to remove 90 to 99% of the polluting gases, present in the exhaust gases, in one working step.
