The heat exchanger (2a) is connected to the heat source (5) by means of the hot water supply pipeline (16) and the hot water discharge pipeline (17). The sorbent bed (2) is connected by means of a vapor channel (8) to the PEM electrolyser (3) from which the hydrogen discharge pipeline (21) and the oxygen discharge pipeline (20) are led. The method according to the invention consists in that in the first stage, sea water is sucked into the evaporator (1). After filling the evaporator, the seawater intake water valve (22) closes and the pump set (12) stops. In the second stage, the evaporator shut-off valve (7) opens and the sorbent bed (2) is cooled with sea water, whereby in the evaporator (1) clean water boils and is sucked in by the sorbent bed (2) as a result of the vacuum it generates. In the sorbent bed (2), the process of adsorption of vapor takes place until the sorbent bed (2) is saturated with vapor. In the third stage, the sorbent bed (2) is cut off from the evaporator (1) and the sorbent bed (2) is heated with hot water from a heat source (5) enabling desorption of water vapor from the sorbent bed (2) towards the anode of the PEM electrolyser (3). Pure hydrogen is produced by the reaction of water electrolysis.

Abstract
A non-transferred arc plasma torch with a method for the generation of plasma jet at high temperatures are disclosed. The main constituents of the torch assembly are a multiple-arc-producing cathode, a coolant distributing cell and an adjustable anode. The cathode comprises primary and secondary annular rods pointing towards the anode. The primary rod is pointing towards the center of the anode and is higher in length and diameter than the secondary ones. The secondary rods are similar in length and width. An internal coolant distribution cell was designed for internal cooling of the rods. The anode was configured to allow external adjustment of the gap between the electrodes. The electrodes were mounted into a jacketed cylindrical housing consisting an internal path within the jacket for efficient recycling of the coolant. The system is initiated by forming multiple arcs between the cathode and the anode leading to the ionization of the forming plasma gas that passed continuously through the torch. Thus, the power efficiency of the torch enhanced and the lifetime of the electrodes increased. Eventually, a thermal plasma jet exits the torch through the anode nozzle.

Abstract
An apparatus consisting of hierarchically elaborated antenna modules is calibrated by steps. Although the AWV can be calculated mathematically based on the required phase shift values of each antenna element for a beam direction to compensate for signal delay. However, in practice, due to hardware implementation imperfection, coupling in signal path for each antenna element within hardware, inaccuracies of implementations, physical misalignment, the mathematically generated AWV does not necessarily provide alignment between transmit beam and receive beam. This subset is sufficient is all practical operation. The subset of AWVs are typically called codebook and the receiver beam points to different direction by using a AWV within the codebook.

Abstract
A gate bias circuit for a plurality of GaAs amplifier stages is a transistor coupled to a temperature compensation current received from a CMOS control stage. A plurality of pHEMPT amplifier stages are coupled to the gate bias circuit and to a control voltage which switches the amplifier stage. A selectively controlled stage pass transistor enables a current mirror between the gate bias circuit and each stage amplifying transistor. The penultimate pHEMPT amplifier stage is coupled to a CMOS amplifier. A CMOS circuit provides both the temperature compensation current by a proportional to absolute temperature (PTAT) circuit and the control voltage enabling each pHEMPT transistor to receive its input signal in combination with the gate bias voltage.

Abstract
A process for the preparation of thermal insulation sheets fashioned from certain unseparated mixtures of post-consumer plastic articles and the article, itself, is disclosed. The mixtures of such articles contain polyethylene terephthalate (PET) and polystyrene (PS) and optionally also articles made of high density polyethylene (HDPE). An unseparated mixture of such articles is provided. This mixture is crushed and shredded to form plastic flakes, and these plastic flakes are then homogenized. Homogenization of the flakes can be carried out either by melt-blending them or by further comminution to produce very fine particles of the mixed plastics. The resulting homogenized mixture of plastic types is then compression molded into sheets ranging in thickness from about 3 to 10 mm.

Resonance fluorescence localization microscopy with sub-wavelength resolution

Zubairy, Muhammad Suhail
Liao, Zeyang

Abstract
The resonance fluorescence spectrum of a number of two-level atoms is driven by a gradient coherent laser field. In the weak dipole-dipole interaction region (separation less than λ/50), a very strong laser field may be applied such that the Rabi frequency is much larger than the dipole-dipole interaction energy. From the spectrum, the positions of each atom may be determined by just a few measurements. This sub-wavelength microscopy scheme is entirely based on far-field technique and it does not require point-by-point scanning, which makes the method more time-efficient. When two atoms are very close to each other (less than λ/50), the position information for each atom may still be obtained with very high accuracy provided that they are not too close to other atoms. The method may be extended to an arbitrarily large region without requiring more peak laser power and only a few measurements are required.
