Abstract: A method of treating waste water is characterized in that it includes phases, in which sludge particles included in the waste water are caused by filtering to attach (10) to hydrophobic organic grains (24), like hydrophobic grains of peat, grains are carbonized by composting (17), and carbonized grains are used as a substrate and carbon source (32, 34) in biological phases (11, 12) of the treatment of waste water. Grains are hydrophobized by drying (18) after composting (17). Grains may be circulated in the process (39, 29) 5 to 10 times, for example. The method may be applied to biological purification of waste water and production of biogas from waste water sludge in a digester. In the method of the invention, sludge is treated and destroyed meanly by means of itself, and the remaining part of it is in solid form and, as hygienized, non-hazardous and suitable for many uses.

As described, the edges 3a of a selected panel are engaged by a selected one of six plungers 21 riding in a block 20 under friction caused by spring 22. As block 20 rises on cables 7 the chosen panel is thus raised; as it falls, cam block 25 disengages the plunger 21; and an arm 23 operated by a solenoid 24 (there is one for each plunger 21) actuates the next plunger to pick up the next panel on rising. During changing of the panels, a Venetian blind 11 is lowered by a motor 12, its slats are inclined by motor 13. Control circuit (Fig. 5, not shown).-Over a period of a week the announcements are changed every half hour. This is achieved by a timer (T) in series with a 30-min.

Abstract: 1,233,544. Semi-conductor devices. MINISTER OF AVIATION SUPPLY. 16 July, 1968 [18 July, 1967], No. 32885/67. Heading H1K. [Also in Division H3] A solid state high-frequency oscillator comprises a body of semi-conductor material in which the interaction between free carriers and lattice waves is sufficiently strong to give an increase in amplitude of the lattice waves to produce oscillation, a sufficiently high voltage gradient being applied across the body to maintain these lattice waves. The frequency of the lattice waves can be varied by varying the applied voltage gradient either continuously or in discrete steps. The semi-conductor material is preferably a piezo-electric material such as cadmium sulphide and the voltage gradient is applied via indium contacts. The oscillation initially builds up from the thermally excited lattice vibrations in the material, these vibrations being of such a wavelength in the body that it is an integral number of half wavelengths in thickness, the body forming an acoustic cavity with internal gain. Circuits are shown wherein the oscillator is used as a frequency modulated transmitter, Fig. 3 (not shown), or a frequency modulated electro-acoustic transducer, Fig. 4 (not shown), wherein the body is bonded to an acoustic medium. The device can be used to measure light intensity, heat, mechanical strain or magnetic flux, and also can be used as a gramophone pick-up or a transmitting microphone.

Abstract: 1,238,011. Radio direction finders. MARCONI CO. Ltd. 22 Nov., 1963 [23 Jan., 1963], No. 2872/63. Heading H4D. In a radio direction finder a number of pairs of aerials are arranged in a circle with the aerials of each pair spaced apart a predetermined distance along a different radius. Each aerial pair is connected to a cardioid forming network and the output from each network is fed to a rotary switching system, associated with a tapped delay line, so that a given number of adjacent aerial pairs have their cardioid signals combined simultaneously to provide the angular direction of the incoming signals. The number of adjacent aerial pairs is selected in sequence round the circle by the rotary switch. The rotor of the latter consists of an inductive-capacitor delay line the tappings along the length of which are each connected to condenser plates at the rotor circumference, the condenser fixed plates, is the stator being supplied from the cardioid networks. The delay line parameters are such that a planar wave front, incident upon the aerial array produces simultaneous output signals from those aerial pairs connected to the rotary switch or a given instant. The required direction is indicated by the angular displacement of a CRT beam.
