Abstract: There is disclosed a fluid motor composed of a helical gear pair wherein an inner chamber has an external helical thread and a cooperating outer member has one more internal helical thread than the number of external helical threads on the inner member. The outer member is secured to one of the sections of a water swivel which is conventional except that it has an axial intake, radial tube and inner member supporting guide, and means are associated with an end of the inner member and with the other section of the water swivel to prevent relative rotation between said inner and outer members while permitting gyration of the inner member in relation to the outer member. Each end of the device has a tapered female thread. The motor may be used either end up. A drill pipe or suitable sub is threaded into one end of the device and a tool is threaded into the other end of the device, directly or with the sub between.

An electromagnetic radiation of which the frequency range is 8800 Mc/s .+-. 10% corresponding to the maximum motion which may be imparted to the reactants of the molecules is directed at the reactants, by an antenna whose axis intersects the axis of the burner inside the reaction zone. A dissociable substance, preferably water with a surface active agent, is used as an additive and injected towards the reaction zone. An electrostatic field is provided around the spray of fuel leaving the burner by a metal ring at a potential of 300 to 25,000 V.

Abstract: An automatic snag grinder having conveyor means to feed a succession of parts to be ground into position before a ram. The ram pushes a part to be ground onto a tilting table whereafter the ram returns. The table tilts to about a 30.degree. angle at which point a pivoted arm moves so as to clamp the part against a stop pad whereafter the table returns to its horizontal position. A main arm swings from a retracted position to one of about 30.degree. so that it is properly positioned with respect to the clamped part, the main arm having a platen which will then be disposed immediately beneath the part and a centering mechanism which is then disposed immediately about the part. A ram for the main arm then fires so that the centering mechanism will clamp and center the part on the platen. Thereafter the main arm moves towards its retracted position and as it so moves it brings the part into contact with a rotating grinding wheel which effectively grinds off protruding gates and the like.

Abstract: Apparatus for selectively conserving water used in association with a commode flush tank is disclosed. The apparatus comprises a generally rectangular plate having ratchet means for wedging the plate between two opposed walls of the tank. The plate further includes a series of longitudinally disposed circular apertures for carrying an elongated stem member downwardly into the tank. The stem member, which slidably receives an elongated float, is carried by the plate so as to maintain the float disposed relative to the buoyant outlet valve of the flush tank. Whereby upon only partial emptying of the tank in response to operating the flush lever, the float contacts the buoyant valve to effect premature closure thereof. In another embodiment, the stem and float may be disposed to one side of the buoyant valve such that a transversely extending retainer clip carried by the float applies a vertical uniform pressure to the top of the buoyant valve in order to achieve premature closure.
