Abstract: A process for the fabrication of metal in shapes of long length and relatively thin cross section by deposition of molten metal on to a substrate and subsequent removal of the shaped metal article therefrom, in which a stream of gas-atomized particles of molten metal is directed on to a substrate, and caused to coalesce and form a coherent layer which is subjected while still hot to hot working, hot working being carried out either (a) before or after removal from a non-deformable substrate or (b) after removal from a deformable substrate.

Abstract: A so-called A.F. or ''''alternating flow'''' hydraulic system comprises a power line interconnecting a generator and a pressure chamber of a receiver, a return line, control valve means at the receiver end of the system and operative to interconnect said power and return lines whereby to produce a return hydraulic flow through the return line, and control means at the generator end of the system. The control means sense the change of flow conditions consequent upon operation of the valve means and substantially preventing pressure pulses from the generator reaching at least a major length of the power line connected to the receiver.

Abstract: In a pacer for artificial heart stimulation, the stimulating pulses produced are inhibited when the pacer detects that natural heartbeats are present. If the pacer detects electrical pulses at a frequency higher than a predetermined threshold frequency, resulting from external interference, the inhibition is suspended, and stimulating pulses are supplied. When interference is detected, the pacer may be arranged to generate stimulating pulses at a frequency higher than normal to avoid the possibility of the artificial pulses competing with natural stimulating pulses.

Abstract: A tachogenerator for measuring the speed of a rotating shaft is described. The tachogenerator has two discs each with spaced peripheral slots; one disc is rotated at a constant speed and the other at the speed to be measured. A light beam is projected through the slots to a light sensitive device coupled to an electrical filter and a signal indicative of speed is obtained from the filter. Electrical noise in the signal from the light sensitive device is reduced by the filter. A further reduction in noise is obtained by using one or more pairs of light beams, with the beams diametrically opposed with respect to the discs. A light sensitive device is provided for each beam and these devices are coupled to the filter input. Instead the devices may be coupled to means for combining the pulse trains generated, to provide the output signal.

Abstract: THE DEWATERING TIME OF A SLUDGE OBTAINED BY ANAEROBIC DIGESTION OF A PRIMARY SEWAGE SLUDGE IS REDUCED SUBSTANTIALLY BY SUBJECTING THE DIGESTED SLUDGE TO AERATION WITH AIR OR OTHER SUITABLE OXYGEN CONTAINING GAS. TYPICALLY, AERATION IS CARRIED OUT FOR AT LEAST 4 HOURS, THE SLUDGE IS ALLOWED TO SETTLE, AND THEN DEWATERED WITHIN TWO DAYS. AERATION MAY BE CARRIED OUT BY MEANS OF DIFFUSED AIR OR, PREFERABLY, BY MECHANICAL MEANS USING A SURFACE AERATOR.
