Abstract: An audio signal processor treats a digitally encoded signal. Units (3, 12) sample the encoded signal and units (8, 13) calculate from the sampled values a correlation function relevant to a particular time frame. The function value serves to control an adaptive echo cancellation algorithm. The sampled signal portions are truncated (2, 5) so that only the arithmetic sign bit of each signal portion contributes to the function calculation. An incoming signal sample is initially treated in an extraction block arranged to determine the arithmetic sign relevant to that signal, the resulting sign bits being fed in sequence to a shift register arranged to store a predetermined number of sign bits. Outputs are provided from selected locations in the register in accordance with a control logic select circuit.

Abstract: Dense cultures of cellulose-producing microorganisms may be produced and used for various purposes by the processes of the present invention. Initially a nutrient medium for cellulose-producing microorganism is prepared which comprises a cellulase preparation. The nutrient medium is then inoculated with cellulose-producing microorganism. The inoculated medium is then incubated under aerobic conditions to facilitate microorganism growth and the production of a dense microorganism culture substantially free of cellulose pellicle. This dense culture may used as an inoculum for a large volume of suitable nutrient medium or may be harvested and the harvested microorganisms utilized, for example as a source of cellular components, for example, such as DNA or enzymes. When a larger volume of nutrient medium is inoculated, a subsequent aerobic incubation of the inoculated medium facilitates the large scale production of cellulose.

Flash-bulbs 69, Fig.6, are wired in parallel with a high voltage source, e.g. a pulse transformer 64, 68, such that on closure of a switch 66 upon actuation of a camera shutter one of the lamps 69 is fired. Further actuations, cause firing of the lamps in sequence according to the voltage required to do so, the lamp requiring the least voltage being fired first. The high voltage source may be provided by a dynamo or Piezo-electro crystal which may be incorporated in the camera. The lamps are filled with a gas which, after ignition, reacts exothermally with the filling, e.g. zirconium. The gas may be oxygen or a volatile fluoro compound on a small quantity of a hydrocarbon. For example, the gas may be mainly oxygen at least 5À4% by volume of CH 4  or 2À1% of C 3 H 6 . A suitable combustible filling is 34À2% by weight of zirconium powder, 25À4% of potassium perchlorate, 1À9% of red phosphorous, 25À8% of lanthanum cobaltite in which part of the lanthanum is replaced by strontium, and 2À7% by weight of nitrocellulose. Electrodes 23, 24, Fig.2, are connected by a glass bead 25. Flash over between electrodes 23, 24 results in explosive combustion of the hydrocarbon when provided, which in turn gives rise to ignition of the zirconium.
