摘要:
A bottle support with clutch includes a tray (1), a small gear (2), a shell (3) and a rotary table (5). The shaft sleeve of the small gear (2) is connected with the shell (3) through a bearing (7). The shell (3) is connected with the rotary table (5). The shaft sleeve of the tray (1) is sleeved in the shaft sleeve of the small gear (2), and a clutch (8) is provided between the shaft sleeve of the tray (1) and the shaft sleeve of the small gear (2). The bottle support of the invention has a simple structure, and works in a reliable manner. The revolution and rotation of the tray (1) are completely consistent with that of the capping head during working, thus improving cover rolling quality.
摘要:
Human obesity is a health problem affecting a significant proportion of the American population. Numerous methods of treating obesity have been developed, but all have serious drawbacks. The present invention discloses a novel class of polymers with either a sulfur atom or an electron withdrawing group between a polymer backbone and a pendant aryl boronic acid group. Polymers having such an electron withdrawing group have been found to be particularly effective in inhibiting lipase in vitro and in vivo. Methods of treating obesity and reducing absorption of fat are also disclosed.

Disclosed are polymers comprising one or more phenyl boronate ester, boronamide or boronate thioester groups. The phenyl boronate ester, boronamide and boronate thioester groups are represented by one of the following structural formulas: Ar in Structural Formulas (I) and (II) is substituted or unsubstituted; and each Z is —O—, —NH— or —S— and is independently selected. Pharmaceutically acceptable salts of the polymer are also included. The aryl boronate ester, boronamide or boronate thioester can be cleaved to release the corresponding aryl boronic acid.Also disclosed are pharmaceutical compositions comprising the polymers of the present invention and a pharmaceutically acceptable carrier or diluent; and methods of treating a subject for obesity with the polymers of the present invention.

Each —NH— in —[NH—(CH2)q]r—NH2 is optionally N-alkylated or N,N-dialkylated and —NH2 in —[NH—(CH2)q]r—NH2 is optionally N-alkylated, N,N-dialkylated or N,N,N-trialkylated. q is an integer from 2 to about 10 and r is an integer from 1 to about 5. R1 and R1′ are independently —H, an aliphatic group, a substituted aliphatic group, an aryl group or a substituted aryl group, or, taken together, are a C2-C5 substituted or unsubstituted alkylene group optionally comprising an amine linking group [—N+(R1a)—]. Each R1 is Structural Formula (I) is preferably —H. R1a is —H, alkyl, substituted alkyl, phenyl or substituted phenyl. Also disclosed is a method of treating obesity in a subject by administering an effective amount of a compound represented by Structural Formula (I) and a pharmaceutical composition comprising the compound and a pharmaceutically acceptable carrier or diluent.
摘要:
The invention relates to oil recovery equipment improved from existing chain oil-well pumping units. Double suspending cables, double balance flexible cables and a counterweight structure without inertial load are used in the invention. There are guide buffer devices and a buffer eccentric regulation shaft coupling in the apparatus according to the invention. Consequently, the load distribution and the stressed condition are more reasonable, the structure is simplified and reliable, and power is obviously economized. The invention has the striking strong points mentioned above in recovering condensed oil, high-condensed oil and bathhypelagic oil.
