Title: Computer system with real-time compilation
Inventor: REIFFIN MARTIN G
IPC: G06F9/44
Filed: 1983-09-07
Abstract: A computer system provides real- time compilation of a high-level language source program contemporaneously as the program is entered or edited at the console. The compiler normally performs lexical and syntactical analyses upon the source code stored in a memory buffer. A video terminal and an editor are provided for entry and editing of the source code. Actuating the terminal keyboard activates interrupt hardware to pass control of the central processor unit from the compiler to the editor. After the latter completes its entry or editing function corresponding to the struck key, control returns to the compiler for resumption of its compilation. The editor controls the advance of the compiler through the source code. The editor also controls the reinitialization of the compiler to cause the latter to recompile the source code, in the event that the editor performs forms operations which may result in changes to source code previously compiled. <IMAGE>

Patent GB-2149605-A (GB)
Title: Image processing
Inventor: MCEWEN ROBERT KENNEDY
IPC: H04N5/217
Filed: 1983-11-04
Abstract: The more modern imaging systems employ solid state detector area arrays which "stare" at the viewed scene (and are thus known as "staring arrays") Unfortunately, these arrays are not very uniform, and the sensitivity and the output absolute value of the detector elements can vary significantly over the array. A normalisation process can be employed, but if such a process is based on the assumption that each element's output is a linear function of its input there may be problems. The present invention suggests a solution to this difficulty; it proposes dividing the operating range of the elements into a plurality of adjacent regions, calculating the gain and offset correction factors for each region separately (upon the basis that the input/output relationship in that region is linear), and then in operation correcting the element's output in accordance to which region it is in. <IMAGE>

Patent GB-2187035-A (GB)
Title: Pyrolysis mass spectrometer disease diagnosis aid
Inventor: SJOBERG ERIC JAMES
IPC: C12M1/34
Filed: 1986-01-27
Abstract: Micro-organisms may be rapidly identified by comparing the mass distribution of molecular fragments of the micro-organisms with those of known organisms. In one embodiment, a pyrolysis process produces the fragments which undergo an ionisation process to enable a mass distribution of the fragments to be distinguished by a quadrupole mass spectrometer and recorded to form a mass spectrogram of primary fragments. An integral computer is used to unravel the composition of the sample spectrogram by taking reference to a data bank of species spectrograms and using an algorithm to elicit the identities of the constituent micro-organism species. In a preferred embodiment, secondary fragmentation generated by collision activated dissociation augments the first fragmentation stage and serves to reveal the structure of the primary fragments, thus enabling complex medical samples to be analysed for their constituent micro-organisms. The invention is capable of identifying micro-organisms embedded in tissue material together with antibiotic, antigenic, toxin and other biological materials.

Title: Optimisation of reactive power regulator operation
Inventor: KUSCHE PETER
IPC: H02J3/18
Filed: 1987-02-27
Abstract: In a method of operating a reactive power compensation regulator having n discrete capacitor stages, the optimum setting of the insensitivity area (C/K value, where C is capacitance and K is the transmission ratio of an associated transformer) is determined in dependence on state of the regulator by the automatic switching-on and -off of the capacitor stages. Repetition of a switching pattern after 2<n> directly following state-charger is used as a criterion for adjusting the C/K value and the procedure is controlled until the C/K value reaches a limiting value which is deposited in a first register as the present optimum value. The method may commence with a maximum C/K value which is reduced until the effect of the first capacitor stage is greater than the C/K value. An average value of a plurality of the determines optimum C/K values may be stored in a second register. A third register may store the number of averagings.

Patent GB-2208150-A (GB)
Title: Water soluble wood preservative
Inventor: DAVIDSON JAMES
IPC: B27K3/52
Filed: 1987-06-27
Abstract: There is provided a water soluble wood preservative, which is also an excellent fire retardant, consisting of a strong solution of sodium octaborate which has been compounded in aqueous solution with non-ionic surfactants and thickeners, e.g. sodium carboxymethyl cellulose, the latter allowing for thick film application by brush but primarily present so that the preservative layer on the wood is self-skimming and is therefore evaporation retarded or slow drying. Such water soluble wood preservatives can also contain other fungicides like sodium fluoride or sodium pentachlorophenate but the main reason for the presence of the octaborate is bifunctional in that it is both a wood preservcative and a flame retardant.
