Abstract: A method for quality control of spot welding in a welding machine, consisting in estimating the energy of the welding spot through the integral of the welding power, the integration extremes of which are determined by the time interval between two successive zero crossings of the welding current.

Abstract: A packaging device, particularly for foodstuffs or technical materials, comprising a bell-shaped vacuum chamber. A single-folded film can be placed in the vacuum chamber and the foodstuff can be inserted from the open longitudinal side of the film. Inside the bell-shaped vacuum chamber there is also provided a first transverse thermal bonding bar, which is laterally adjacent to a cutting blade, and a second thermal bonding bar, both bars being L-shaped. At least one nozzle for introducing gas is furthermore provided so as to face the longitudinal or transverse open side of the single-folded film.

Abstract: An adjustment and control unit for gas burner valves provided with a bimetal rod-and-tube thermostat which is arranged on a rocker supporting the flow control element of a valve. A translational motion actuator is arranged so as to push on the rocker, on the opposite side with respect to the thermostat, and is kinematically connected to a knob by way of coupling elements which convert rotary motion into a translational motion. The coupling elements provide two distinct transmission ratios, each at specific rotation positions.

Abstract: A device for program-controlled variation of the composition of a gaseous mixture for inflating a tire for performing the method, comprising a first source of at least one main gas, a second source of at least one additional gas, at least one first compressor suitable for compressing to a preset pressure a gaseous mixture of at least said main gas and additional gas, at least one dispenser of compressed mixture which is connected to the delivery of said compressor, and further comprising at least one mixer for said at least one main gas and said at least one additional gas which is suitable for delivering a gaseous mixture having a desired composition, a gas analyzer means arranged downstream of said mixer, valve means for controlling the flow between said mixer and said first and second gas sources, and program control means arranged to control said valve means in response to control signals from said analyzer means.

Abstract: Polyester resin foamed sheet, mono e biaxially stretched usable for the production of containers for beverages and foods, having a density lower than 700 kg/m3 and a crystallization rate such that, when the sheet is heated at 120° C. for 5 minutes, the crystallinity does not exceeds 15%. The aromatic polyester resin used for preparing the foamed sheet can be mixed with an aliphatic polyester resin to impart biodegradability and/or compostability to the sheet or with 1-10% by weight of a polyamide.

Abstract: A motor wheel for driving the driving wheel of an industrial vehicle and the like, comprising upstream of a two-stage rotary-ring reduction unit, a gearbox with fixed-ring epicyclic gear train, with at least two positions which respectively correspond to the high or travel speed and to the low or working speed. A parking brake is further provided downstream of the gearbox with respect to the motion input.

Abstract: A prefabricated concrete panel for building floors in civil or industrial structures, comprising a concrete body with a reinforcement provided with portions which protrude from one of the larger faces of the body of the panel which constitutes extrados of a floor and are designed to be embedded in the casting of the topping of the floor. At least one first shaped sheet is provided inside the body of the panel, is made of thermally insulating material, is interposed between the two larger faces of the panel body and forms, between the two larger faces of the panel body, a ventilation chamber which is composed of a plurality of mutually connected cells.

Abstract: A process for synthesizing complexes of platinum(II) with iminoethers having the formula: [PtIIX2(L)(L′)], where X is a monoanionic ligand, L is an iminoether ligand and L′ is an amine group or, exclusively for the case of cyclic iminoethers, a second iminoether ligand. The platinum(II) complexes according to the present invention are suitable for the production of medical remedies having a broad antitumoral spectrum. The complexes of platinum(II) with iminoethers according to the invention are furthermore suitable as agents for modifying nucleotide bases into antisense and/or antigene oligonucleotides.

Abstract: A massager to be inserted in the back of massage chairs, comprising a frame which supports a massage assembly constituted by a plurality of massage wheels actuated by at least one gearmotor; the frame is movable in a vertical direction, and the massage assembly is independent of the frame and can move at right angles to a plane in which the frame is formed.

Abstract: A stator for synchronous motors with more than two poles, comprising a plurality of sectors formed by lamination packs which are joined at their ends, forming as a whole a closed annular structure, at least one pole shoe protruding from each one of the sectors. The ends of the stator define, at each connecting region, thanks to respective facing shaped portions, at least one tab with mutually opposite undercuts, one for each end; the tabs accommodate corresponding portions of an elastic connecting element which surrounds the tab and rigidly couples the sectors.

Abstract: A fluid control valve with a butterfly-type flow control element, with high operating reliability, comprising a valve body which is crossed by a passage with an inlet and an outlet which can be connected to two branches of a duct for a fluid to be controlled by means of the valve. The valve body accommodates, in an intermediate region of the passage, a butterfly-type flow control element which can be actuated in order to open or close the passage. The valve body supports, in the intermediate region of the passage, an annular gasket which can be engaged by the flow control element in the closure position. The valve body is provided in at least two parts which are mutually coupled at the region that is occupied by the annular gasket and lock the annular gasket between the parts in a mutual coupling position.
