Title: Slabs and blocks of granulated stone with cementitious binder - cast from mix having binder slurry of defined water:cement ratio in amount to give specific mini-slump test result followed by vacuum treatment and vibration
Inventor: TONCELLI MARCELLO
IPC: B28B/
Filed: 1996-01-29
Granted: 1998-09-23
Abstract: Blocks or slabs of artificial stone are produced from a mixture containing natural stone granulated to a controlled particle size and a water - cement slurry. having a water content of 0.25 - 0.36 parts by weight of water per part of cement together with a conventional plasticiser to give the slurry a fluidity such that when subjected to a mini-slump test it forms a very thin layer with rounded shape of diameter about 20 cm. The components are mixed with the amount of slurry being slightly in excess of the void fraction of the granulated stone, mixing being carried out under vacuum when the product is to have a thickness of 5 cm or more. The mixture is spread into a layer in a mould, still under vacuum if applied during mixing, and a very high vacuum applied for a very short time to effect complete de-aeration. The mould is then vibrated at 2000 - 4800 cycles/min under a vacuum lower than that of the preceding operation but not less than 80 mm of mercury. If the thickness is not more than 5 cm vibration is continued for at least 60 secs. Finally the mould is transferred to a setting and initial hardening station after which the product is removed and stored on shelves for final hardening. Also claimed is a plant for manufacturing cementitious slab products which includes an array of hoppers and silos with associated measuring devices for discharging materials to a mixer and a section for filling moulds together with the apparatus necessary to carry out the above operations.

Abstract: The present invention relates to a method and device for conducting a search in a codebook. This codebook consists of a set of pulse amplitude/position combinations each defining a number L of positions p and comprising both zero-amplitude pulses and non-zero-amplitude pulses assigned to respective positions p = 1, 2, ...L of the combination. Also, each non-zero-amplitude pulse assumes one of q possible amplitudes. According to the method, a subset of combinations is pre-selected from the codebook, and the search is limited to this subset to reduce complexity thereof. To pre-select the subset, an amplitude/position function is pre-established in relation to the sound signal. Pre-establishing the amplitude/position function includes pre-assigning one of the q possible amplitudes to each position p by (i) processing the sound signal to produce a backward-filtered target signal D and a pitch-removed residual signal R', (ii) calculating an amplitude estimate vector B in response to the signals D and R', and (iii) for each position p, quantizing an amplitude estimate Bp of the vector B to obtain the amplitude to be selected for that particular position p.

Abstract: Effektreguleringsmekanisme for signaler i en foroverkanal, for en fjerntliggende stasjon (6) i et kommunikasjonsnett hvor det også er basestasjoner (4a, 4b, 4n). Effektreguleringsbit som bestemmer effekten i en returkanal sendes av en av disse basestasjoner (4) i en foroverkanal (10a). I den fjerntliggende stasjon (6) måles disse bit fra basestasjonene eller via flere signalveier som kan ha innbyrdes forsinkelse, bit-ene kombineres, filtreres og gir et forbedret mål på kvaliteten i foroverkanalen. De kommandobit som gjelder effektregulering i returkanalen (12a, 12b) anses å være mer upålitelige og tas ut fra reguleringssløyfen. Stasjonen (6) frembringer et sett kommandobit for foroverkanalen ut fra målingene og sender disse bit til samtlige basestasjoner som står i forbindelse med den. Hver av disse basestasjoner innregulerer forsterkningen for overføringen i foroverkanalen (10a) i samsvar med målinger av kommandobit-et for denne kanal. Forsterkningen korrigeres periodisk slik at feilmottak av bit-ene for foroverkanalens effektregulering ikke samler seg opp.

The latter is controlled by a gate 29 and is directed by guide surfaces through a central opening in a member 33 to a dished member 17; the members 17, 33 form an assembly rotating coaxially with but independently of the rotor 15. The sand is upwardly directed by the dished member 17 to strike the lip 44 of member 33, by which is it redirected downwardly and falls along the inner surface of the housing 54A, 54B. The path of the sand thus passes three times through the zone of projection of the liquid binder, at 71A, 71B and 71C. The dished member 17 carries a fan blade 157 to prevent material adhering to the inner surface of the housing. Air or other gas may also be supplied through a hollow support 56A and passages 118 to fan blades 109 mounted on the member 17, and through apertures 119, 126 to the interior of the rotor 15.
