Abstract: Disclosed is a pump for controllably dispensing an additive into a stream of liquid and mixing therewith, the pump comprising: a pump body having a passage into which a liquid stream is introduced, and from which a combination mixture of the additive and the liquid stream is discharged; a turbine supported for rotation within the passage, the incoming liquid stream striking the turbine in a manner as to impart rotation thereon; an auger housing connected to the pump body, and having an entrance end into which an additive is introduced and an exit end from which the additive is discharged into the passage, such that the additive mixes with the incoming liquid stream; and a helical lifting auger mounted on a supporting drive shaft fixedly attached to the turbine, the auger rotatably disposed within the auger housing so as to produce a fluid flow through the auger housing, the lifting auger configured to accept the additive from the auger housing entrance end; and move the additive through the auger housing to t

Abstract: An automatic shut-off valve is used at the inlet point of a fuel line carrying a gaseous or liquid fuel into a house or the like, the valve being adapted to terminate the flow of gas or liquid upon the experiencing of a shock or vibration by the valve as would be produced by an earthquake, with the valve head being so positioned to be actuated by a sudden surge of flow to shut the valve in the event a ruptured gas line causes a quick inordinately rapid gas or liquid flow in the system. The principle utilized to actuate the closing of the valve as a function of a certain minimum amplitude of vibration or shock is a ball weight which in normal use rests on a pedestal which in turn maintains the valve head away from the valve seat in the supply line, this ball being designed to topple from its supporting pedestal during an earthquake or other vibration, thus freeing the valve head to seat under spring tension such as to block the fluid flow.
