Patent GB-2070326-A (GB)
Title: Improvements in or relating to electron tubes
IPC: H01J31/50
Filed: 1981-01-16
Abstract: In streak tubes it has been found that a glow discharge can develop, possibly caused by ionization of alkali from the processing of the photocathode. It has been suggested that a D.C. bias on the R.F. deflection plates (10) can prevent the glow but this disturbs symmetry of the image. It is proposed to prevent the glow by applying equal opposing D.C. biasses (16, 17). Bias can be applied to separate, split, bias plates, but it is preferred to apply it between the deflection plates. One or both (10a, b, 10c, d) of the deflection plates may be split but split plates are treated as one for the purposes of the R.F. deflection. <IMAGE>

Title: Magnetic coil apparatus for metal working and welding
IPC: B21D26/14
Filed: 1981-08-07
Abstract: A magnetic coil assembly B comprises an insulating body (1) (9) and a conductor (2) (10). The assembly B is such that it can be located around a section of a component to be treated without having to be passed over the adjacent sections of the component.

Patent GB-2092779-A (GB)
Title: Device for controlling the engine revolutions of an i.c. engine
IPC: F02D31/00
Filed: 1982-01-04
Abstract: A desired value transmitter (1) coupled to an accelerator pedal (2) supplies a comparator (3) with a desired signal corresponding to an engine speed. A speed transmitter (4) supplies the comparator (3) with an actual signal corresponding to the instantaneous actual engine speed. An electronic control system (6) receives a signal representative of the difference of desired and actual signals. A driver circuit (7) is controlled from the control system such that in the event of the desired signal being equal to the actual signal a throttle valve (8) is retained in a position proportional to the desired signal. In the event of a higher desired signal than actual signal, the throttle valve (8) is opened further. In the event of a higher actual signal than the desired signal, the comparator (3) supplies a closure signal to magnetically operated valves (9) in the fuel supply lines (11) to injection nozzles (10) associated with respective cylinders of the internal combustion engine. <IMAGE>

Title: A process for the production of a polypeptide
Inventor: CAREY NORMAN HENRY
IPC: C12R1/865
Filed: 1982-06-11
Abstract: A process is described for the production of the proteolytic enzyme chymosin. The process involves cleaving chymosin the precursor polypeptides methionine-prochymosin, preprochymosin or methionine- chymosin expressed from a host organism which has been transformed with a vector system carrying the relevant gene. The gene sequence of preprochymosin is given. The vector systems used are plasmids adapted for the transformation of either bacterial or eukaryotic host organisms. E. Coli and Saccharomyces cerevisiae are specific examples of suitable host organisms. There is also described an oligonucleotide capable of being used as a specific hybridisation probe or transcription primer for mRNA containing the nucleotide sequence coding for chymosin. A microassay for chymosin activity is also described.
