The present invention provides a rotary seal including a first part having an axial sealing lip and a second part having an axial counterface against which the axial sealing lip bears. According to the invention, a rotational one of the first part and the second part is provided with a reservoir for retaining a volume of grease at a location radially inward of the axial sealing lip. The reservoir is designed such that the movement of grease under the action of centrifugal force is prevented, while the movement of base oil, which bleeds from the volume of grease retained in the reservoir, is allowed. As a result, the supply of base oil to the sealing contact takes place for a longer period of time, which extends the life of the seal.

In a method for preparing bio-oil by catalytic pyrolysis of microalgae with high fat content by a molecular sieve, HZSM-5, MCM-48 or HY molecular sieve is taken as a catalyst, and the catalytic pyrolysis of the microalgae with high fat content is realized in a down-flow fixed bed reactor. Compared with lignocellulose biomass, the temperature for the catalytic pyrolysis of the microalgae with highfat content is lower, and the yield and the quality of the obtained bio-oil are higher, thereby being very conductive to energy-saving and high efficient production of the bio-oil; furthermore, the composition of the bio-oil can be changed by changing the catalyst, thereby meeting the different market demands and having great market application prospect.

It is a cage that is formed of a resin and that holds balls serving as rolling elements. The cage includes an annular base portion, and a plurality of claw portions that are formed to be arranged at constant intervals on the circumference of the base portion and to protrude therefrom. A pocket for accommodating the ball is formed between each pair of adjacent ones of the claw portions. In the resin cage for a ball bearing, thinning recesses are formed in end parts 11a of the claw portions and a rear surface of the base portion, respectively.

The invention discloses a feeding method of high-quality pork of Laiwu black pigs. The feeding method comprises the following steps: firstly dividing the growth and development period of the Laiwu black pigs into a nursing period, a growing period and a fattening period, wherein the weight in the nursing period is 15 to 30 kg, the weight in the growing period is 30 to 60 kg, and the weight in the fattening period is 60 to 90 kg; setting amino acid models according to different periods, wherein in the nursing period, an energy-protein ratio is 19.98 to 21.54, DE (Digestible Energy) / lysine is 296 to 409, DE / methionine is 900 to 1701, DE / methionine + cystine is 450 to 850, DE / threonine is 415 to 785, and DE / tryptophan is 1500 to 2835; in the growing period, the energy-protein ratio is 21.11 to 22.79, DE / lysine is 326 to 464, DE / methionine is 1004 to 1378, DE / methionine + cystine is 525 to 624, DE / threonine is 488 to 581, and DE / tryptophan is 1693 to 2268; in the fattening period, the energy-protein ratio is 22.40 to 24.25, DE / lysine is 362 to 534, DE / methionine is 1116 to 1456, DE / methionine + cystine is 563 to 651, DE / threonine is 518 to 624, and DE / tryptophan is 1915 to 2485; designing a formula according to the ratio between the amino acids in the models, preparing daily ration, and feeding in stages. According to the feeding method disclosed by the invention, the lean meat percentage of the black pigs is increased, the content of intermuscular fat of the pigs is improved, and the pork yield and the evaluation score of the pork are increased.

The invention relates to a protein-saving compound feed for young megalobrama amblycephalas and a preparation method of the protein-saving compound feed. The feed is mainly prepared from the following raw materials: 3-5% of fish meal, 17-22% of soybean meal, 10-15% of rapeseed meal, 10-15% of cottonseed meal, 8-10% of peanut meal, 3-5% of whole-milk extruded soybean, 5-8% of whole-milk vegetable seed, 5-8% fermented cottonseed meal, 3-5% of corn lee protein, 8-10% of wheat bran, 8-10% of wheat shorts, 1-2% of alpha-starch, 0.05-0.1% of bile acid and salt emulsifying agent, 0.015-0.03% of glycyrrhetinic acid, 1% of monocalcium phosphate and 1% of compound-premix for intensively-cultured fishes. The preparation method comprises the following steps of: stirring the raw materials in a stirring machine and introducing steam to prepare grains with the grain size of 1-2mm, and then, dewatering and cooling to the room temperature. By using the protein-saving compound feed for the young megalobrama amblycephalas, provided by the invention, the problem of unbalanced nutrition of the compound feed in the current culture of the young megalobrama amblycephalas is solved, the physical condition of the of the young megalobrama amblycephalas is improved, the growth speed of the young megalobrama amblycephalas and the feed utilization ratio are increased, and the feed production cost and the pollution to a water body in the culture process can be reduced.

The invention discloses a feed additive for improving the flavor of livestock meat and prolonging the shelf life of the livestock meat. The feed additive comprises the following main raw material components in part by weight: 1 to 5 parts of magnesium methionine, 4 to 8 parts of insect chitosan or / and selenoprotein, 1 to 5 parts of sodium glutamate, 1 to 5 parts of premix for use in livestock latter fattening period and 0.5 to 1 part of vitamin. The feed additive prepared by the invention can be added into livestock feed directly. When the livestock are fed by the feed containing the additive, the normal metabolic function of the digestive system, particularly the liver tissue, of the livestock can be maintained; the accumulation amount and position of the metabolic reactions of the fat, proteins, micro elements and the like can be regulated; and finally, the flavor of the livestock meat can be improved and the shelf life of the livestock meat can be prolonged. The raw materials of the invention are widely available and can be purchased in market easily; the preparation process is simple; and the feed additive is convenient to use and environmentally-friendly, and avoids any harmful residue.
