Abstract: A process for the treatment of effluent which contains solid, sedimentable, colloidal and truly dissolved substances and whose impurities are at least partially of an organic nature, with a reduction in the chemical and biochemical oxygen demand, is characterised in that flocculation aids are added to the effluent and the solids-containing effluent is passed by gravity through a supporting fabric located in a suspending device. During the filtration step, a combination filter composed of a) this supporting fabric and b) a primary filter layer of the solids separated off is formed, by means of which the further effluent introduced is freed of the major part of the solid particles. The filtration through this combination filter has the effect that not only the sedimentable and also a substantial part of the colloidally dissolved substances, but also a major part of the truly dissolved substances are separated off, so that a filtrate is obtained, for the treatment of which a biological oxygen demand is required which is reduced by up to 90 %, relative to a municipal effluent freed of solids. The process can be combined with equipment for biological and/or chemical-physical treatment. Equipment in which the process according to the invention is carried out is described.

IPC: F02B1/06

Abstract: A piston type internal combustion engine is arranged to use, in a time dependent process, the shock compression and expansion waves generated by the combustion of the fuel to pump highly energized compressed air from a reservoir chamber adjacent the combustion chamber and in communication with the latter through a restricted passageway into the combustion zone during the entire combustion process.  The combustion chamber, reservoir chamber and passageway are configured to promote controlled pumping of air from the reservoir into the combustion chamber throughout combustion due to the interaction of the compression and expansion waves.  The air in the reservoir is fuel-free and is preferably placed in the reservoir during an aspirated intake event by controlling the timing of fuel flow during intake and the mixture of the charge at the intake port.  The preferred embodiment provides the reservoir chamber in the piston near its working face and the passageway is an annular gap between a radial lip of an annular member supported above the piston and the cylinder wall.

Abstract: A component for use in a toy construction kit comprises plastics building elements having groove and/ or tenon joining means and plastics sheets for forming cut out parts. With such kits it is possible to make up shaped models by cutting up the sheets and securing them together. The component is injection-moulded in one piece from plastics material and has an undercut tenon 5 and a thin flexible base 6 for adhesively securing the tenon to a supporting surface. When so secured - for example to a surface 2 of a shaped model - the tenon can releasably engage a groove or slot on a building element 3. <IMAGE>

Abstract: A sling fastening buckle comprising a buckle frame in the form of a bottom plate in which is formed an aperture, the marginal portions of said plate being angularly bent to form two channels, in which two bars are displaceable. The bars have an essentially oblong cross-sectional shape with rounded edges. A sling is placed about a load so as to encircle the latter while the two end parts of the sling are passed through the aperture, between the bars and arranged around the associated bar. The end parts of the sling are then passed between the bars and the edge limiting the aperture. After tightening the sling about the load, the bars are forced outwards towards the edges of the aperture, thus applying a clamping action on the sling which is thus locked in position. The locking ceases when a pulling force is applied on the end parts of the sling and the sling may then be further tightened. The sling is released by positioning the buckle frame at an angle relative to the support.

Abstract: The invention relates to the field of automotive engineering. The aim of the invention is to use combined relative travel limitation in the case of a tilting driver's cab to avoid, in particular, oscillations about its diagonal, vertical movements and transverse movements at the rear end of the driver's cab. The object of the invention is to provide an asymmetrical three-point mounting for tilting driver's cabs which permits a combination of the relative travel limitation in the vertical and horizontal directions. The essence of the invention consists in the fact that, with the use of rubber-metal-spring elements, known per se, and a main lock which is known per se and combined with a buffer, the rear, asymmetrical bearing is arranged in a horizontal plane with the corresponding front bearing. The horizontal distance of the rear bearing from the outer edge of the frame side member is smaller than/equal to the distance of the front bearing from the outer edge of the frame side member. The invention is used in tilting driver's cabs on utility vehicles together with hydraulic or mechanical tilting-force assistance. <IMAGE>

In relatively small individual telephone networks using digital transmission techniques and comprising a few intermediate stations and terminal stations, a need has arisen to branch groups having less than 30 channels. To branch such groups in a digital manner, i.e., without first decoding the signals to voice-frequency signals, a phase compensating device includes four switches, four time multiplexers, and two frame phasers and two control units for controlling the switches and time multiplexers. The device comprises two identical units, and is suitable for branching other digital information, besides data signals having a standard frame structure. Moreover, the transmission rate of the branched line may differ from that of the main line by using a rate modifier.

Abstract: The metering system and method provides an electronic power meter for simultaneously producing digital pulse trains proportional to power and to VARS or Q. In the preferred embodiment, the metering system employs delta-minus-sigma modulation of the voltage signal which produces a modulated output signal used for gating the analog current signal, multiplying voltage and current. The product of voltage and current is then supplied to another delta-minus-sigma modulator (90), which serves as a convertor outputting a pulse train. The converter (90) produces separate pulse trains for each polarity of the power being measured. VARS or Q readings are produced by delaying the output of the modulator (30) by a selected amount to produce the necessary voltage lag, after which the delayed modulated signal is supplied to another multiplying gate. A second converter (90) is used to output VARS and Q. A metering method is also disclosed, as well as an offset compensation system (70, C1) for use with metering systems.
