摘要： A smart water pump includes a housing (5). An outlet box cover (13) is arranged on the top of the housing (5), and a power plug (1) is arranged at an upper part of the outlet box cover (13). A circuit board (2) is arranged within the housing (5); a rotor (4) and a stator (6) are arranged under the circuit board (2). A motor front cover (7) is arranged at a lower part of the housing (5); a turbine housing (8) is arranged under the motor front cover (7); an impeller (10) is arranged within the turbine housing (8), and the impeller (10) shares a rotary shaft (3) with the rotor (4). A water outflow pipe (14) is arranged on one side of the housing (5), and a water level sensor (12) is arranged on the other side of the housing (5). The water level sensor (12) includes a sensor box (15). A sensing probe is arranged on the sensor box (15), and includes a high water level probe (16), a low water level probe (17), and a ground probe (18). The high water level probe (16) is shorter than the low water level probe (17), and the low water level probe (17) is shorter than the ground probe (18). Water pumps employing the water level sensor (12) can control the rotation of the water pump on the basis of the water level, ameliorating a common scenario with existing water pumps in which the water pump does not work when water is available and works when water is unavailable.

摘要： An industrially acceptable process for the preparation and purification of cis-2-methylspiro(1,3-oxathiolane-5,3′)quiniclidine from a cisitrans mixture of isomers. Treatment of the mixture with an organic sulfonice acid generates a less soluble acid addition salt that is enriched in the cis-isomer. Recrystallization or pulping using various organic solvents allows for enrichment of the cis-isomer by filtration. These new sulfonic acid salts of the cis-isomer of 2-methylspiro(1,3-oxathiolane-5,3′)quiniclidine prepared according to the present invention could be further converted into the hydrochloride salt by any known procedures such as treatment with a base and then hydrochloric acid salt formation or exchange of the sulfonic acid salt with hydrochloric acid.

摘要： A computer enclosure includes a cage with a pair of brackets fixed therein for rotatably supporting a mother board tray to which a mother board is fixed. The cage includes a front panel, a rear panel, a top panel and a bottom panel forming a receiving space for receiving the mother board tray. The brackets support shafts that are rotatably received in bores defined in the mother board tray allowing the mother board to be mounted to and/or removed from the mother board tray at a position outside the cage thereby reducing the size of the cage and thus facilitating miniaturization of the computer enclosure.
