Liquid regenerative filtration equipment with a pressurized tank (2) with lower inlet (3), upper outlet (4), candles (7) hanging from a plate (8) separating the upper part (2.1) from the lower part (2.2), where a filter medium (6) forms a precoat (6.1) on the candles (7), and a vibrator (9) and a propeller (10) for agitating the filter medium (6) and regenerating the precoat (6. 1), where each candle (7) incorporates a one-way check valve (12), which prevents the filtered liquid from flowing in the opposite direction. There is a free space (7.2) between the valve (12) and the plate (8) so that it can flow backwards towards the lower part (2. 2) of the tank (2) and clean the candles (7) by regenerating the precoat (6.1). The lower inlet (3) of the liquid to be filtered incorporates a diffuser (13) that distributes the flow to the inner base of the tank (2).

A fabric cutting machine capable of a straight cut or chamfer cut, comprising a cutting module (4) with upper cutting bridge (4.1) and lower support (4.2) with at least one saw for cutting the fabric (t), once arranged and tensioned, either with a straight cut (r) or chamfer cut (c). This bridge comprises: either a single moving saw (4.10), tilting, which can be positioned vertically or inclined; or a single vertical saw (4.11) with horizontal sliding; or two saws, one vertical (4.11) and one inclined (4.11'); or two vertical saw types, one single (4.11) and one double saw (4.12). Rollers (4.13) tension the fabric (t) over a head (4.21) of the lower support (4.2) with a flat portion (t1) and two inclined (t2) for straight (r) or chamfer cutting (c).

Multipack bottle carrier, intended for transporting groups of two or more bottles (b), held by their caps (t), being formed from a laminar piece (1) made of cardboard or similar material, die-cut with circular holes (2) provided with tabs (3), arranged on both sides of a set of parallel fold lines (4, 5) and two openings (6) which, when folded, define a central vertical fold (7) incorporating a carrying handle, characterised in that the laminar piece (1), in addition to the parallel fold lines (4, 5) one central (4) and two lateral (5) between which the handle openings (6) are interspersed, comprises diagonal fold lines (8) extending from the handle openings (6) towards the respective ends of the laminar piece (1), which, when folded, define respective triangular areas (9) that rest on both sides of the central vertical fold (7), fitting onto the shoulders of the bottles (b), at least those located at the ends of the grouping. The laminar piece (1) comprises four diagonal fold lines (8), two on each side, extending symmetrically from the respective handle openings (6) to the opposite lateral ends (1.1) of the laminar piece (1), passing tangentially through the circular holes (2) located at the outermost positions on both sides of the piece. (1) Comprises moreover three circular holes (2) arranged symmetrically on either side of the parallel fold lines (4, 5) and the diagonal fold lines (8), which collectively define the central vertical fold (7) The circular holes (2) of the laminar piece (1) include tabs (3) only along a portion of their inner contour, located solely on the portion opposite the position of said central vertical fold (7) and its carrying handle.

The invention relates to a power regulation method for a heating element and control system for implementing said method, the method comprising the application of the cycle stealing technique to adjust the power supplied to the resistive load at multiple levels, such that the modulation period is enlarged, reducing the frequency of the current signal that modulates the carrier, in order to reduce the generation of harmonics. The control system comprises a controller (2) connected to a power regulator (3) acting on the heating element (1), such that said controller (2) adjusts the power supplied by the regulator (3) to the resistive load of the heating element (1) by the cycle stealing technique in fine steps.
