IPC: A61P33/00
Filed: 2020-07-20
Abstract: The invention provides a method for manufacturing nanop articles of total alkaloids from Eomecon chionantha Hance. The steps for the preparation are as follows: a) Comminuting the medicinal parts of Eomecon chionantha Hance and mixing with an alkaline substance, adding water to mix uniformly, and then standing overnight; b) adjusting the pH of the mixture, collecting and drying the resulting precipitate, and then extracting with an alcohol, followed by concentrating and filtrating; c) refrigerating the filtrate and spraying into a supercritical crystallization kettle countercurrently to prepare nanoparticles; d) collecting nanoparticles at the bottom as the nanometer particles of total alkaloids from Eomecon chionantha Hance. This method is mainly to extract and purify the alkaloids from the active parts in the Eomecon chionantha Hance, wherein the alkaloids are converted into ion pairs and filtered. The content of the total alkaloids in the product reaches 60% or more, and the diameter of the main portion of the obtained nanoparticles is 1-15 11m and the smallest diameter is 500nm. The process is environmentally friendly and non-pollution, simple and suitable for large-scale production. Nanoparticles of the total alkaloids have high absorptivity and high bioavailability, and will be more widely used in the ﬁelds of feed additives, medicine and food.

Title: Machine for drawing poultry - on a continuous transporter with minimal damage to the rest of the bird especially the liver
IPC: A22C21/06
Filed: 1976-06-23
Abstract: Machine for drawing poultry, hung by the ankles on a continuous transporter. An opening between the breastbone and the tail has been made previously. A tool enters the bird through the opening. The tool is a unit moving back and forwards in a straight line. It has a pivoted extension which has a tapered split for gripping the gullet. The extension is in line with the unit during the inward stroke and at the end of the stroke it swings in the direction of the wind-pipe. The split grips the gullet and the ends of the extension a pressed against the ribs. As the unit is withdrawn the pressure against the ribs is maintained. An external support is placed behind the bird. As the unit withdraws the extension brings the intestines and lungs with it. The ends of the extension are two balls one on each side of the split. The removal of the lungs is ensured. The absence of sharp projections and the position of the extension during the inward stroke reduce damage to the rest of the bird, esp. the liver. Changes in the size of the birds are not important and do not affect the operation.

Title: Greenhouse solar heating system - pumps air around circuit with heat storage vessel and water heater to vary heat output
IPC: F24S10/55
Filed: 1980-03-19
Abstract: The solar heating system using air as a heat exchange medium, has the heat collectors arranged in parallel, and interconnected by ducts across their ends. Between the building to be heated such as a greenhouse (1) and the heat collectors (3) is a fan (2) which forces the air through the ducts (6b, 6c). The air then passes from the collector to a hot air storage vessel (4) and a heat exchanger (5) before travelling along a return line (7) to the greenhouse. The storage vessel has a high capacity, the heat exchanger can be used for hot water. There is a bypass line (9) connecting the output side of the collectors with the greenhouse, and for rapid heating up this line is used disconnecting the remainder (4, 5) of the circuit. Then this line is shut off, and heat is stored in the storage vessel. The output of the pump can then be varied to maintain a required temperature.
