Abstract:
A substance with sedative effect comprises a therapeutically effective amount of a gamma-pyrone such as comenic acid, meconic acid, chelidonic acid, and alike in a pharmaceutically acceptable carrier. When administered at a daily dosage of between 5 and 200 mg of active ingredient per kilogram of a body weight of a patient, the substance can be used to treat various neurotic disorders such as insomnia, anxiety, neurosis, depression as well as withdrawal symptoms for drug addiction patients, especially for patients addicted to opioid-based drugs. The substance can be delivered in a number of ways of systemic administration of a pharmaceutical agent including oral, parenteral, transdermal, and transmucosal administration. For drug addicted patients, the preferred method of administration involves a subcutaneous implant providing a continuous release of an active ingredient at an effective daily rate over the entire treatment period ranging from 5 to 30 days, and preferably from 13 to 20 days.
Abstract:
A method and device for reducing or eliminating axial thrust in a rotary machine such as a centrifugal pump or compressor by altering the fluid pressure in a cavity (31) or (32) formed between a rotor (20) and a housing (10). The device contains a disk (40) placed along the rotor (20) for subdividing the fluid in the cavity (32) in such a way that all annular gap leakage flow is channeled and pumped through the space (42) between that disk and the rotor from the center of the pump towards the periphery. As a result, the pressure in the cavity (32) is altered to reduce and control the axial thrust on the rotor (20) which becomes independent of the wear state of the shaft seals (61). In another embodiment, the step of flow subdividing is achieved by providing a set of braking vanes (56) along the periphery of the cavity (31) for reducing the rotational speed of the fluid coming from the cavity as well as from the annular gap and a stationary disk (50) is placed along the interior wall (11) of the housing (10) for directing the radial flow of that fluid towards the center of the pump.

Abstract:
A method and system are presented for the combustion of hydrogen sulfide mixed with other gases for simultaneous recovery of sulfur and energy from hydrogen sulfide at higher efficiency. The amounts and velocity of the hydrogen sulfide into the reactor is selected in such a way that it is not possible to burn the hydrogen sulfide in a normal thin reaction zone during its combustion that normally prevails in almost all flame combustion devices. The injected hydrogen sulfide gas is mixed in a thermal reactor with fresh air and hot active combustion gases in the reactor on account of internal jet pump effect and self-induced entrainment. The reaction is exothermic so that the chemical energy present in hydrogen sulfide is recovered together with the sulfur that is tapped off from he process. The reactor process can also be used for other gas and chemicals that require controlled reactor thermo-chemical environment. Various reactors are shown capable of controlling the formation of a thermal distribution flow pattern based on the position and position and direction (and other factors) regarding fluid introduction within a combustion chamber of the reactors.
Abstract:
A new rapid optical specific absorption rate (SAR) system is disclosed. The rapid optical SAR system has ability to measure and map the power deposited in a flat phantom or other phantom filled with a transparent simulant fluid. Absolute rates of temperature increase in the phantom by photo thermal techniques are measured. For example, the temperature increase and gradients in the phantom bend the path of a laser beam, which may be aimed at a position sensitive detector. The spatial SAR may be mapped and SAR differences between different telephones and telephone orientations, for example, can be distinguished. The system is non-invasive and non-perturbing of the SAR distribution in the phantom, can measure at locations up to the interior surface of the phantom, and provides thermally-based SAR measurements that do not necessarily require constant calibration.
