Abstract: A needle syringe has a plunger and a needle for filling and dispensing liquid from the cavity. The cavity has finger clip with movable locking pins. The plunger has at least one set of grooves corresponding to a specific dosage for the needle syringe, the specific dosage of the groove being demarked by a marking ledge that indicates a change to a deeper depth section of the groove. The locking pins are configured to rest in the at least one set of grooves, such that when the plunger is removed, the locking pins pass within a first shallow section of the groove, pass over the ledge, and continue to pass in the deeper depth section of the groove. When the plunger is depressed in a first partial dispensing movement, the locking pins pass in the deeper depth section of the groove until the plunger depression is temporarily locked when the locking pins reach the ledge, where the dose remaining in the cavity is the specific dosage.

Abstract: Hot water heater system (such as, for example, a gas-powered hot water heater system) that includes a self-powered automatic pilot light and which is not connected to any external source of electrical power.

Abstract: An automatically actuated regulation system for a natural gas pipeline having flow control unit, a vibration sensor, a gas flow meter, a trigger unit, and a microprocessor. The microprocessor actuates the flow control unit when two conditions are met. First, there must be a vibration which surpasses a predetermined threshold. Second, flow in the natural gas pipeline must have increased over the flow rate before the vibration. The system can be configured to store gas usage data and, in one embodiment, transmit the data to another location through the use of a modem or other communication means.
