Title: A submersible nano-bubble generating device and method
Inventor: Scholten Bruce
IPC: B01F23/2373
Filed: 2020-03-13
Abstract: An apparatus for producing nano-bubbles in a volume of liquid is described. The apparatus includes a motor having a rotatable shaft, an axially rotatable permeable member couplable to a gas inlet, and a rotatable tube support coupled to the rotatable shaft of the motor and having an inner cavity that houses the axially rotatable permeable member. When rotated, the axially rotatable permeable member is rotated so that the surface velocity of the rotatable permeable member simulates axial turbulent flow above the turbulent threshold in the liquid that allows the liquid to shear gas from the outer surface of the axially rotatable permeable member, thereby forming nano-bubbles in the liquid.

Abstract: A reciprocating external combustion engine wherein energy is transfered to air acting as a working gas by injection into the air of liquid water at a high temperature and pressure. The liquid water is injected either directly into the cylinder or into a preliminary mixing chamber. The water acts as a heat-transfer medium for heating the air. Spontaneous vaporization of the liquid water on injection increases the pressure of the air which drives the piston before being exhausted. The exhaust water is recovered and recycled. The cylinder is scavenged and refilled with a fresh charge of air.

Abstract: A method of reducing curling in pressed sheet material is disclosed. The undeformed sheet material is pressed to sequentially form opposite and separated bend radii. During such pressing, the separating section between the bend radii is subjected to a sliding fulcrum to bend and unbend said section as well as rub one side of the panel to impart a first strain. The panel is counter rubbed on its opposite side to impart a strain opposite to the first strain to reduce or eliminate curling.

Abstract: A semiconductor memory device comprises a sense amplifier (1) formed on a semiconductor substrate (10), paired bit lines (BL) connected to the sense amplifier and memory cells (MC) connected to the bit lines. A predetermined bias voltage is applied to the semi-conductor substrate, and a reading operation is performed by amplifying, by means of the sense amplifier, a voltage difference produced between the paired bit lines due to accessing the memory cells. A voltage of reverse phase relative to noise on the bias voltage applied to the substrate is fed to the semiconductor substrate via a capacitance (21 formed on the substrate, to cancel the noise. By virtue of this feature, the influence of such noise can be minimised in the semiconductor memory device of the present invention.

Abstract: Bei einer Analog-Anzeigeeinrichtung ist ein Zeiger (1) durch einen Schrittmotor (2) rückstellbar, der nach einem Rückstellbefehl eine konstante Anzahl von Impulsen erhält. Damit erreicht der Zeiger aus jeder Stellung mit Sicherheit den Anschlag, der der Null-Stellung entspricht. Um dabei die mechanische Belastung des Anschlages (6) und von Getriebeelementen (3 und 4) zwischen dem Zeiger und dem Schrittmotor gering zu halten, werden die Impulse zur Rückstellung zunächst mit einer verhältnismäßig niedrigen Pulsfrequenz und dann mit einer höheren Pulsfrequenz erzeugt. Dadurch läuft der Schrittmotor mit einem verhältnismäßig großen Antriebsmoment sicher an, gibt aber nur noch ein kleineres Antriebsmoment ab, wenn der Anschlag in der Null-Stellung erreicht wird.

Abstract: In accordance with the principles for transcutaneous measurement of a blood parameter, such as the partial pressure of a blood gas, an electrochemical measuring electrode device (1) is applied to the skin surface (2) of a person. The electrode device comprises a body (10), e.g. a thick film substrate, which is thermostated to a predetermined temperature and, furthermore, includes sensor means (11) together with a membrane (14) confining an electrolyte solution within an electrolyte reservoir (15). Furthermore, the electrode device includes a jacket comprising an annular metallic body (16), a metallic body (4) and a thick film substrate (8) which is thermostated to the same temperature as the body (10) of the electrode device. When the body is brought into contact with the skin surface, an annular surface part of the jacket is also brought into contact with the skin surface so that a virtual heating jacket is established in the skin beneath the annular surface part so as to substantially direct all heat flow from the body to tissue directly beneath the skin surface. By measuring the power supplied for thermostating the body to the predetermined temperature, the local capillary blood flow in the tissue (2) beneath the skin is measured, and the blood parameter in question is measured by means of the sensor means (11). In an alternative operational mode, the electrode device is adapted to measure deep body temperature by thermostating the jacket to a temperature so that the temperature registered by a temperature sensor of the body and the temperature registered by a temperature sensor of the jacket are identical to one another and, consequently, identical to the deep body temperature.

Abstract: An impedance matching stripline transition for microwave signals which are conducted from a stripline circuit on one laminate (2) to another laminate (4) through a number of intermediate laminates (3). The connection between an incoming stripline circuit (21) on one laminate (2) to the outgoing stripline circuit (41) on the other laminate is performed as a short coaxial line. The outer conductor of the coaxial line is formed by a number of through-plated holes (12, 13, 23, 33, 43) in horseshoe form around a central conductor of through-plated holes (24, 34). The outer conductor is connected with the earth plane (31, 11, 45) of the laminates. They serve simultaneously as suppressor of not desired modes in the microwave signals which is supplied to the transition via the conductor (21).

Abstract: An assembly (10) of a rigid shell expansible blood reservoir (20), heater (40), and hollow fibre membrane oxygenator (60) is integrated into a self-supporting unit. A visible concavity (22) closed by a flexible membrane (24) forms a variable volume liquid and air-tight blood reservoir (20) attached to a blood heater (40) which in turn is attached to a hollow fibre membrane oxygenator (60). The assembly stores, heats, oxygenates and purifies blood by passing oxygen through the lumens of a mat (70) of small diameter gas-permeable hollow fibres supported on a cylindrical core (68) as blood flows over the outside surfaces of the fibres in a small, easy to use, safe, integrated oxygenator (60) which avoids blood contact with ambient air as blood circulates through the assembly.

A spool is mounted for rotation in the first handle jaw and includes a forward flange and a rearward flange between which the front clip of the row of clips may be positioned. An L-shaped rod extends from the spool and is pivoted in one direction by one of the handles when the handles are closed to rotate the spool to permit passage of the closed clip from the jaws after the jaws are subsequently partially opened. The rod is also pivoted in a second. opposite direction after the handles are partially opened to orient the spool to block feeding of the next clip beyond the jaw region.

Abstract: Process for improving the fillability of tobacco, such as cut tobacco leaves or ribs and tobacco additives by treating the tobacco in an autoclave with a containing nitrogen and/or argon at pressures up to 1000 bar, with subsequent decompression and a gas heat treatment. The tobacco or the treatment gas supplied to the reactor and/or the decompression step are carried out in such a way that the discharged tobacco which is thereafter supplied to a subsequent heat treatment has a temperature, at introduction to the heat treatment step, below 0 DEG  C. This is achieved by precooling the treatment gas prior to supplying it to the autoclave or cooling the treatment gas while supplying it to the autoclave and/or additionally cooling the autoclave and/or precooling the tobacco and/or injecting subcooled or liquefied treatment gas into the autoclave. The process includes multistage treatment gas whereby supply and decompression steps are carried out in a cascade-like manner.
