Abstract: In a method for ultrasonic surveillance of spaces, an ultrasonic transmitter is used which radiates reproducible transmit pulses into the space, and an ultrasonic receiver which receives the reflection signals triggered by these pulses. Both processes occur simultaneously so that an interference field is produced in the surveillance space. With reference to the beginning of the transmitting period, measurement levels are recorded at defined measuring times and compared with one another. An alarm transmitter is activated or kept deactivated in accordance with the result of the comparison. To eliminate false alarms due to thermal effects in the surveillance space, it is proposed to allow the measuring periods for two measurement profiles to begin in each case only after the interference field has settled. During the evaluation, the measurement profiles are first superimposed above one another, with reference to the same measuring time, and then shifted in parallel with respect to one another step by step in the direction of their measurement level, with the aim of achieving the best-possible match between them. The deviations from matched measurement profiles obtained section by section are used as criterion for the case of an alarm. <IMAGE>

Abstract: Fibres used for insulation and absorption purposes can be optimally processed in a dust-free manner by mixing the absorption/insulation material shortly before leaving the injection hose or the spray gun with a special foam and then discharging it as a common mass. In this case, the foam can be produced as such beforehand from water, air and a special foaming agent or from binding agent, if necessary with water and air, with or without the addition of foaming agent, and then added to the fibre material and mixed with this. It is however also possible to combine the production process of the foam with the mixing with the fibres or to influence the foam by adding air. The injection hose (3) and the spray gun (7) have, at the outlet, a double tube (8), into which the foam tube (6) leads and whose inner tube (13) is equipped with sluices (10, 11), it being possible for the outer tube (9) to have bores (14, 15) for supplying air. <IMAGE>

Abstract: In magnetic resonance imaging various error sources lead to deterioration of the image quality. One class of errors is formed by errors which vary only slowly over the time required to sample a data line but vary substantially over the time required to acquire data for the complete magnetic resonance image. These error sources are, for example external magnetic fields, motion due to respiration, drift in amplifiers or drift phenomena in permanent magnets due to temperature influences. It is proposed to utilize mutually intersecting data lines in the Fourier domain so as to estimate these error sources and to use these estimates to correct the data sets obtained before execution of image reconstruction.

Abstract: A system is provided for removing acid gases from gaseous streams which has particular application in reducing the incidence of sulfide and other acid gas excursions. The present invention addresses the disadvantages of prior absorption techniques by cosely monitoring and maintaining a reaction zone temperature profile within a contactor to improve and control an exothermic reaction between acid gas components and an aqueous amine absorbent. A temperature profile is maintained by adjusting relative flow rates of the feed gas stream and aqueous amine in the process to reduce the incidence of excursions.

Abstract: The liquid jet recording head (701,101) comprises a plurality of arranged liquid discharge ports (704,111) for discharging the recording liquid, a plurality of liquid passages (110) each communicating with each liquid discharge port and a thermal energy generating means (103) provided in the liquid passage for acting thermal energy on the recording liquid therein. The discharge ports (704) are so arranged that the opening areas of the liquid discharge ports located at both end portions in the arrangement of the liquid discharge ports are larger than that of the liquid discharge port located at a central portion. The generation of change in liquid droplets discharged from the liquid discharge ports (704) can, therefore, be prevented, which arises due to the difference of viscosity that is caused because the temperature of the recording liquid is higher at the central portion of the liquid passages (110) and lower at both end portions thereof, depending on the arrangement relation of thermal energy generating means (103), and a recorded image having no unevenness in recording density can be formed.

Abstract: A high frequency SSB radio transmitter has an envelope amplitude modulator (3) for varying the envelope of an r.f. signal source based on an error signal from envelope detectors detecting the envelope of the input and output waveform. It also has a phase modulator (4) in a main feedback loop for varying the phase of the input waveform based on differences detected in phase detector (10) between the instantaneous phase of the input and output r.f. signal. To overcome the problem of spurious outputs from phase detector (10) resulting from the cross-over points of the SSB waveform when there are carrier breaks and other problems, a subsidiary, phase lock loop (12) feeds a signal derived from the error signal to phase modulator (13) to tend to hold the input A, B in such a phase relationship that the output is zero. To cope with large phase shift errors between input waveform and output resulting from when the power amplifier changes frequency or temperature variations e.g. at the antenna, a broadband phase shifting network (17) is brought into operation when a dual voltage comparator (19) senses that the signal fed to modulator (13) passes a value corresponding to its extremes of adjustment.
