Abstract: By means of reverse transcription of mRNA coding for a desired polypeptide, there is obtained a set of overlapping fragments of duplex cDNA, which together correspond to the whole mRNA molecule. The fragments have overlapping regions bearing sites for restriction enzymes, such that cutting and ligation gives DNA corresponding to the polypeptide. This is introduced into a vector in reading frame with a promoter. Transformation of a microorganism enables expression of the polypeptide. The construction via fragments enables large molecules to be made. Thus, human serum albumin (HSA) is produced by E. coil transformed with plasmid pHSAI. This includes DNA made from fragments derived from reverse transcription of mRNA from human liver.

Abstract: A lateral acceleration control method for a missile permits short response times to commands even of great amplitude. It comprises the association of an aerodynamic control system having large lateral acceleration capability, called PAF, with a force control system close to the center of gravity, having a moderate lateral acceleration capability, but with very short response time, called PIF. The overall response to a command includes the usual response of the aerodynamic automatic pilot to which there is added the response from the force control system, such that in the presence of a constant order, after a delay equal to the response time of the PAF, the PIF is entirely available for a new action.

Abstract: The invention provides a travelling wave tube having a directly heated cathode. Cathode material is applied in a depression in one U-shaped member of a high resistance alloy material and the return path for heater current is provided by another U-shaped strip member beneath the first. The configurations of the two strip members are similar so that stray magnetic fields generated by the equal but opposite currents flowing therein, tend to neutralize one another. In another embodiment the two strip members are replaced by generally cylindrical members, one member being within the other. The surface of the member providing the return path for heater current is polished where it faces the member carrying the cathode material so as to reflect back heat radiated by the last-mentioned member.

Abstract: The guide system for a thread entering a stocking knitting machine having a cylindrical array of needles which rotates constantly and a supplementary thread guide which can skip over selected groups of needles to form the heel of the stocking is complemented by a supplementary concentric array of guide plates backed by an annular cam above the level of the plates alongside the tops of the needles but below the level of the cap through which the filament enters coaxially. The cam is shaped to induce a centripetal movement of the plates to be followed by a centrifugal recoil at appropriate intervals controlled by interruption of the motions of a pair of concentric toothed racks having an intermediate pinion and pins which can be intercepted by deployment of radial check rods. Slows the main array of needles to rotate continuously while causing the amount of thread deployed to be varied to suit the shape of a heel or other modification of the stacking profile so that the circumferential threads do not exhibit excessive residual tension.
