Abstract: A pulse-width modulated circuit applies a voltage (+V) across a load (32) in accordance with a command signal (I). The command signal is con­verted into first and second trains of pulses (x, x′), by electronically comparing the command signal, and its inverse, with a triangular dither signal (38). These two pulse trains (x, x′), and two more pulse trains ( y , y′) obtained by taking the complements of the original pulse trains, are applied to a pair of bridge circuits (48, 50). The load is connected to both bridge circuits. Both bridge circuits include electronic switch­ing devices (60, 62, 64, 66, 68, 70, 72, 74) actuated by the pulses. The bridge circuits are configured such that when a pulse is present, from either the first or the second pulse train, no net voltage appears across the load. At all other times, substantially the entire power supply voltage is applied across the load. Compared to pulse-width modulated circuits of the prior art, having similar pulse frequencies and power supplies, the present circuit reduces the undesirable effects of current ripple through the load by a factor of four. This reduction is due to the use of two alternating pulse trains, which doubles the effective fre­quency of pulses, and to the fact that the maximum voltage excursion of the signal across the load is no greater than the absolute value of the maximum power supply voltage available. As a result, the present circuit has a much higher bandwidth than circuits of the prior art having compa­rable voltage and frequency parameters.

Abstract: A transmitter using a gallium arsenide FET (27) in a power amplifier (26) and having a biassing circuit for generating a gate biassing voltage for the FET, a first power supply (29) for supplying a first power to the biassing circuit and a second power supply (30) for supplying a second power to the power amplifier, the second power being higher in voltage than the first power and being produced at a time delay from production of the first power at a start condition of the transmitter, wherein the first power is supplied to the biassing circuit through a first diode (31) with a voltage drop to thereby reduce the gate biassing voltage below a normal one so that an undesired signal is suppressed at the power amplifier. The second power is delivered to the biassing circuit through a second diode (32) so that the biassing circuit is driven by the second power to produce the normal biassing voltage. Although a multistage amplifier is used for signal amplification prior to the power amplifier and is supplied with a power from the second power supply, a number of stages of the multistage amplifer is not necessary to be increased for attenuating the undesired signal at the start condition because of the signal suppression of the power amplifier.

Abstract: A coating process can serve to encapsulate either solid particles or liquid droplets or both. The process comprises a first step of forming a melt of a coating material in which the solid particles or liquid droplets as a dispersed phase. This melt is then destabilised by adding solid particles and/or by cooling. This causes the melt to crumble to a particulate product consisting of dispersed phase encapsulated with the coating material. 
     Examples of coating material are organic polymers, soap fatty acid mixtures and non-soap surfactants. Materials which can be encapsulated include bleaching agents and perfume.

Abstract: The plastic bubble packaging film is manufactured by bonding together two sheets of high density polyethylene (F1, F2) along two sets of joint lines set at right angles to each other and forming a network of sealed envelopes (14) that encapsulate the bubbles. The bond is effected in two successive stages by two pairs of fluted rolls (1a-1b, 7a-7b), one profiled circumferentially, the other axially, between which the sandwiched sheets are caused to pass. The surfaces of the rolls are heated in order to soften the sheets along the joint lines and enable the bond. On passing through the first pair of rolls, lenghtwise seals are effected so as to form tubular envelopes (13) into which air is blown, whereupon the smaller envelopes (14) are sealed off and the bubbles encapsulated by the transverse action of the second pair of rolls.

Abstract: A scheduler provides for global (intra-loop) scheduling of instructions to enable better utilisation of machine resources, in particular for a range of superscalar processors. The scheduler uses control and data dependence information, which is summarised in a program dependence graph, to move instructions well beyond basic block boundaries. The scheduler can be tuned to schedule instructions for a range of superscalar machines through the use of a parametric machine description for the range of machines and a sets of heuristics for specific machines. The scheduler allows for the scheduling of both 'useful' and 'speculative' instructions.
