Abstract: With an auxiliary lock operated by a built-in battery, it is desired to prevent the door from being kept locked even if the battery dies. The auxiliary lock body is provided with first and second voltage detecting means for detecting that the voltage of the battery has lowered to predetermined voltages. If the first voltage detecting means detects that the voltage of the battery has dropped to a predetermined voltage, the fact is alarmed. Then, if the second voltage detecting means detects that the voltage of the battery has dropped further, the actuator is activated to open the lock by pushing down the bolt inside the lock surface before the battery dies, thereby preventing the door from being kept locked even if the battery dies.

Abstract: A sustained release pharmaceutical composition which includes a pharmacological material; a biological binding agent for the pharmacological material; and a matrix of a water-insoluble but water-swellable hydrophilic polymer.

Abstract: A movable base jack includes a jack pad, a guideway integrally connected to the pad and a jack column connected to a wheel assembly which rolls in the guideway. The wheel assembly can move in a longitudinal, rotational and arcuate direction in the guideway and is captivated to the pad.

Abstract: Material is fed into a revolving drum which has an interior configuration, preferably in the form of a helical blade, to convey the material at a controlled rate through the drum. A low temperature gas, such as nitrogen, is introduced into the drum downstream when viewed in the direction of travel of the material, in a liquid state at a controlled rate through a spray nozzle system, thereby continuously exposing the material to the cooling effect of the gas. A portion of the gas is recirculated from the upstream end to the downstream end of the drum. The material is pre-cooled in the upstream portion of the drum. After exiting from the drum, the material may be crushed or impacted and separated.

Abstract: A sustained release pesticidal composition which includes a pesticide; a biological binding agent for the pesticide; and a matrix of a water-insoluble but water-swellable hydrophilic polymer.
