Inventor: QINGSONG LI
IPC: B01D15/40
Filed: 2022-12-23
Abstract: Disclosed is high-efficiency supercritical equipment, and relates to the related technical field of chromatography. The high-efficiency 5 supercritical equipment comprises a gas-liquid separator and a carbon dioxide filter which are connected through a pipeline, wherein the gas- liquid separator is used for separating a gas-liquid mixture and conveying separated gas to the carbon dioxide filter, the carbon dioxide filter is used for filtering the gas, and the filtered carbon dioxide is cooled by a 10 refrigerator in a supercritical fluid chromatography system and then is reused. According to the high-efficiency supercritical equipment, pure carbon dioxide can be obtained at the component collection part of the industrial-grade supercritical fluid chromatography system, and the problems that the carbon dioxide consumption of the industrial-grade 15 supercritical fluid chromatography system is large and the carbon dioxide cannot be recycled are solved.

Title: Solid propellant charge assembly for rocket motors - has parallel cordite plates bonded to incombustible carrier preventing collapse
IPC: F02K9/14
Filed: 1969-05-29
Abstract: The assembly includes a carrier and a number of separate plates of propellant. The plates extend laterally from a surface of the carrier, which is of non-combustible material, and bonding agents secure an edge of each plate of propellant to the carrier. The plates may be separate elements attached individually by an edge to the carrier. Alternatively, the plates may be attached to each other by strips of propellant forming a continuous surface with the edges of the plates; this surface being bonded to the carrier. The bonding is effected by a duplex film comprising phenolformaldehyde resin in contact with the carrier and polyvinyl formal or cellulose acetate in contact with the propellant. The assembly forms a charge with less tendency to bending an collapse with consequent misfiring of the motor when differences in pressure are set up over the length of the charge.

Title: Down packaging machine for pillows - has container with paddle wheel discharging material into perforated compression and filling shaft (OE 15.12.77)
IPC: B68G7/06
Filed: 1976-09-28
Abstract: The machine for filling down into packages (12) has a chamber (10) filled with the down, inside which rotates a paddle wheel (16) so that the down is pushed through an opening (20) at one end into a perforated filling shaft (38) assisted by suction.

Title: Receiver input circuit with high signal=to=noise ratio - has mixer operated by VCO over control loop with coordinated frequency and phase
IPC: H03D7/18
Filed: 1980-02-12
Abstract: The input circuit replaces parametric receiver input stage circuits and has a higher signal-to-noise ratio in front of the demodulator. It consists of a parametric downstream mixer and a series-connected demodulator. The mixer is supplied by a V.C.O. synchronised in frequency and phase via a control circuit so that the following terms are met: p - 2z and p-z-3z, where p is the voltage control oscillator frequency and z the intermediate frequency. The mixer is terminated by real resistor at the mirror frequency to enable power amplification. Pref. a series-connected low noise preamplifier is provided for the mixer. For microwave range the parametric mixer may be used as a preamplifier at the signal frequency. With frequency modulated input signal the demodulator forms a phase detector, between which and the mixer, is incorporated an i.f. amplifier. A low pass filter is connected at the output of the demodulator, and the l.f. can be tapped at the same.

Title: Wind-powered generator using Darrieus rotors - coupled to common generator using universal joints ensuring synchronism
IPC: F03D3/02
Filed: 1982-05-13
Abstract: The turbine efficiently uses the available wind since it is more efficient to use several small rotors than one large one, the mass of a Darrieus rotor increasing in proportion to the cube of the dia., while the energy obtained increases only in proportion to the square. A four rotor version has the rotors mounted on axes which form a square with sides at 45 degrees to the vertical. The points of the square are supported by a mast and cross-member. The axes of the two rotors on each side are coupled together by universal joints, and the two sides are connected via a gearing system to the drive shaft of an electric generator. The coupling ensures that the four rotors are in synchronism, thus reducing vibration and air turbulence to a min.

Title: Chain structure for securing locked posts
IPC: E01F13/02
Filed: 1992-11-12
Abstract: The invention relates to a removable no-parking post (locked post) and associated ground anchor (foot piece), which are a widely recognized feature of our cities; they are used at entrances and exits, on market squares, in residential areas, in short wherever it is necessary for it to be possible to temporarily remove a post of this nature in order to temporarily allow traffic to pass through. Since the post is removable, many such posts are lost through theft, vandalism and carelessness; in a town such as Dordrecht in the Netherlands, approx. 50 of these posts disappear every year. This invention seeks to prevent this, specifically by on the one hand attaching a chain 1 around the rotatable pin 2 of the post and on the other hand by attaching the chain to the inside of the hollow shaft 4 of the ground anchor via a hole 3 which is to be made in the top base plate of the ground anchor. <IMAGE>

IPC: B01D35/143
Filed: 1993-01-28
Abstract: A filtration apparatus with exchangeable filters for hygienic filtration of contaminated fluids. A tubular filter housing (1) has a central bore (2) as a receiving chamber for a filter cartridge. O-shaped rings (5,6) are mounted at the ends and in the centre of the wall of the receiving chamber, and these prevent fluid from leaking around the filter. The filter housing has a fluid entrance opening (7), and, diametrically opposite to it, an exit (8) lying lower. A filter cartridge has a filter element (11) and two end caps (13 and 14). The rear end cap (13) has an annular opening (16) which is in connection with the filter chamber (12) within the filter element. In an assembled state, the fluid entrance (7) is in connection with the annular opening (16) in the filter chamber. Contaminated fluid is sucked in through entrance (7) and it proceeds through the filter to fluid exit (8). The replacement of the filter takes places by pressing in a new filter cartridge at the top of the filter housing, which causes the soiled filter to be pressed out at the underside without this needing to be contacted by hand. <IMAGE>
