Abstract: A fast low angle shot ("FLASH") NMR method is described, which uses radio frequency excitation pulses having a flip angle substantially less than 90 degrees, and subsequent reading gradient reversal for producing a gradient echo signal. The small flip angle pulses create an equilibrium state between longitudinal and transverse magnetization, which allows to apply the radio frequency pulses repeatedly with high repetition rate to produce gradient echo signals of essentially equal strength, without any intervening delay for magnetization restoration or recovery.

Abstract: Organic waste, especially organic household garbage, is leached in a leaching apparatus for washing out any water soluble organic substances and water soluble heavy metal salts. Air is supplied into the apparatus during the leaching for aerobically decomposing or rotting the organic substances. Non-soluble substances are discharged from the leaching apparatus for further treatment. A liquid flow-off component containing solved substances is withdrawn from the leaching apparatus, collected in an intermediate tank and introduced into an anaerobic solid bed reactor wherein anaerobic bacteria reduce or decompose the liquid flow-off component to form bio-gas which is withdrawn from the solid bed reactor for use or storage in a low pressure tank. The heavy metal salts are precipitated into water non-soluble sulfides and the flow-off is returned for further leaching to the leaching apparatus in a substantially closed circuit in which any lost leaching liquid is replenished.

Abstract: Air is extracted by a collection zone (3) (fig. 3) through duct (8) and four holes (7) from chamber (4) located between the wearer's head and the polystyrene; the resulting low pressure that is created pulls other air through openings (5) at the sides of the front; the entry of the air by such openings is aided by the fact that a slight pressure is present inside the helmet in the front zone by dynamic effects, and this entry generates a true and real circulation that, preventing stagnation of the hot air, creates a real inside conditioning effect. Further the air, which enters by the lower part of the helmet and by the openings to eliminate the condensation on the visor, is sucked upward by chimney effect which also contributes to reducing the steaming of the visor itself.

Abstract: During a heating operation, the absorption heat generated when a condensed solution absorbs refrigerant vapour is imparted to circulated cold or hot water flowing through a first cold/hot water heat exchanger to convert the water into hot water. Condensation heat necessary for condensation of refrigerant vapour by a water heating device is supplied to circulated cold or hot water flowing through a second cold/hot water heat exchanger to convert the water into hot water for heating. At this time, since the refrigerant solution evaporates on an inner wall surface of a cylinder by absorbing the heat of the air, the heat obtained from the air is added to the heat obtained from the high-temperature regenerator. A heat pump effect can be obtained.

The structure of the opener is mainly based on a firm cylindrical body (1) inside which there has been installed pressing parts (2) which functions as the gripping means of the screw cap. The device functions so that when it is pressed against the top of the screw cap to be opened the pressing parts start to close strongly squeezing the screw cap from its sides. When the device is twisted, the cap either opens or closes. Structurally the functioning of the device is based on pressing parts which have been installed against the inside surface of the body with an axle so that they can turn vertically at an angle of approx. 25 DEG  in a downwardly slanting position close to a horizontal plane. The pressing parts are designed so that above the squeezing section there is an outwardly projecting tip (7), which when pressed against the top of the cap turns the pressing parts upwards so that the distance between them diminishes, the screw cap is squeezed between the pressing parts, and the device is ready for use.

Abstract: The method of the present invention comprises contacting a suspension of viable lymphocytes with a solution containing a membrane potential sensitive fluorescent dye. The contact between the lymphocyte suspension and the MPS dye is maintained for sufficient time to permit labelling of the lymphocytes by the MPS dye material. The labelled lymphocytes are passed individually through a focused source of excitation energy causing any MPS dye material to fluoresce. The fluorescent emission from each cell is recorded as a pulse and the number of pulses of each intensity are recorded. The distribution of the number of pulses versus the intensity is prepared distribution is bimodal. A first peak includes pulses of low fluorescence intensity and a second peak comprises pulses of high fluorescence intensity. A ratio of the total counts of low fluorescence intensity to the total counts of high fluorescence intensity produces a factor which distinguishes lymphocytes derived from bodies afflicted with malignancy from bodies which are not afflicted with malignancy.

Abstract: A speech amplifier circuit increases the maximum perceived loudness at the speaker (412) and reduces distortion at high volume levels without increasing the power consumed by the speech powder amplifier (410). When a low volume is selected by the volume control (414), the microcomputer (418) sets the step attenuator (406) at a correspondingly high attenuation level and the high-pass filter (408) is bypassed. As the volume control (414) is advanced and the speech power amplifier (410) is 12 dB into clipping, the microcomputer (418) activates the high-pass filter (408) and simultaneously steps the gain of the step attenuator (406) by 6 dB.
