摘要:
Light source with a pleasant light, similar to natural light, for LEDs, such as LED Arrays, SingleChip or Multichip LEDs, OLEDs and remote phosphor LEDs, having an emission spectrum (10) defined by a curve that is a function of the wavelength (λ) and light intensity (I) and provided with three emission peaks (R, G, B) disposed in correspondence to the wavelengths (λ) that are at least relative respectively to the colors red, green and blue.
摘要:
Containing structure (10) for a lift machinery, the structure being made of metal or other suitable material, consisting of a housing (18) in which at least one of the constituent walls is defined by leaves hinged to a permanent wall (14) of the building or to another wall of the housing (18). The object of the present invention is to provide a containing room or structure for lift machinery, occupying very little space and at the same time providing enough space for maintenance work. A permanent fixed room within the building for the lift machinery is not required.

Luminous source with pleasing light having a light emission spectrum with color temperatures comprised between 2500K and 6500K and provided with three peaks of light emission (R, G, B) situated in correspondence to the red, green and blue colors.
摘要:
The sponge production process consists of heating a mould (3) of Teflon or silicone to a temperature between 60°C and 70°C, feeding a mixture comprising a plastic material and a reagent into the mould, allowing the mixture to rise for a time less than 30 minutes, and extracting the finished sponge (10) from the mould. In this manner an absorbent sponge is obtained without an impermeable surface skin. The plant comprises a conveyor (2) for conveying a mould (3) to mould heating means (4), followed by feeding means (5). The plant then comprises rising means (7) arranged to retain the mould for a time such that the mixture contained in the mould undergoes rising, followed by means for discharging the sponge (10).
摘要:
The present invention relates to a process for the preparation of a biodegradable composite substrate for the growth of plants with gamic or agamic propagation, which comprises mixing for a short period of time a matrix of a natural origin, water and a selected polyurethane prepolymer with a low reactivity to form a paste which rapidly hardens forming open cells (macroporosity) and binds the natural matrix.
摘要:
The process for manufacturing a multi-element sponge consists of mixing together a polymer (1) and a reagent (2) to form a mixture (3) to be expanded to produce a spongy mass (4), casting the mixture (3) in a mould (6), depositing an insert (7) onto said mixture (3) and allowing the mixture (3) to expand while maintaining the insert (7) pressed against it, so that on termination of expansion the insert (7) is directly connected to the spongy mass (4).

摘要:
Hydraulic circuit for passenger and freight elevators and the like with intrinsic safety comprising substantially a flow control valve (10), a magnetic descent valve (12), a check valve (14), an overpressure valve (16) and a magnetic starting valve (18) in which said magnetic starting valve (18) is controlled electrically only during the descent phase and the overpressure valve (16) is closed in the absence of an electric command.
