Title: Gatling jet
Inventor: LOIZEAUX PHILLIP D
IPC: A61H33/02
Filed: 1997-08-08
Abstract: A jet for use in spas and hydrotherapeutic reservoirs having a first set of nozzles aligned in a plane at the water entrance side of the jet and a second set of nozzles aligned one-to-one with the first set of nozzles at the water exit side of the jet. A chamber separates the two sets of nozzles and includes a slot which is used tointroduce air into the fluid stream. The amount of air introduced into the chamber is controlled by the user by rotating the jet within its housing from a maximum air intake position to a "no-air" intake position, air being introduced through a slot surrounded by a rectangular seal structure. A housing is provided to mount the jet within the wall of a spa comprising a rear wall mounting, an end cap, and a front wall mounting.Water is introduced to the multiple jet structure via a single horizontal water inlet. The servicing of multiple jets by the single water inlet and air line improves plumbing reliability and further reduces labor by minimizing the number of plumbing joints.

IPC: G01B21/28
Filed: 1998-12-04
Abstract: The effective flow area of a restriction in a gas flow passage, such as that of a gas turbine nozzle or vane, is determined by use of a large reservoir containing pressurised gas which is discharged through the passage in a blowdown operation in which the ratio of back pressure of the restriction to gas pressure in the reservoir is maintained below critical for sonic flow. Timer means may be used to measure the time for a predetermined fall of pressure in the reservoir whilst there is sonic flow through the restriction.

Abstract: A method and apparatus to repair dents formed by a golf ball impacting the surface of a golf green.  A restoring tool is mounted to the top of the handle of a putter, and this tool comprises a base member and a ground penetrating portion which is formed as a pair of tines and which is rotatably mounted to move from a stowed position flush against the base, to an operating position where it extends at right angles to the base.   The putter is inverted so that the end of the handle can be positioned against the raised edge of the dent.  The tines (outwardly extending) are moved to penetrate into the soil at a location outwardly of the raised edge of the dent, and the compression surface of the base member presses the sod layer downwardly and displaces the underlying ground layer laterally to fill into the recess portion of the dent.  This also causes the displaced portion of the sod laterally over the dent.
