Abstract: A pressure regulating valve adapted to be interposed between a pressurized liquid supply whose pressure varies and a spray nozzle or other liquid applicator from which the liquid is discharged. The valve, actuated only when the pressure of the incoming liquid exceeds a predetermined minimum level, functions to maintain the flow of liquid fed to the applicator at a substantially constant pressure level regardless of variations in the pressure of the liquid supply, and to cut off flow automatically should the supply pressure fall below an acceptable level.

Abstract: A sealing assembly for a rotary drive shaft that extends through the hull of a boat, the outboard end of the shaft being coupled to a propeller and the inboard end to a marine engine for rotating the propeller. The assembly includes a cylindrical housing joined by a flexible hose to a tube in the stern of the boat through which the shaft passes. Received within the housing is an annular bearing whose bore diameter depends on the size of the shaft whereby the bearing installed in the housing has an internal diameter appropriate to the size of the shaft being sealed by the assembly. Coupled to one end of the housing is an annular cap having an elastomeric lip seal therein that frictionally engages the shaft to prevent sea water from leaking into the boat. A reservoir defined by an annular space within the housing between the lip seal and the bearing is continuously fed with water to cool and lubricate the lip seal.

Abstract: The present invention is concerned with a training device which can be worn by a user to teach the correct body position when hitting a baseball comprising: an adjustable sensing mechanism fitted on the batter's helmet to sense the movement in three mutually perpendicular axes of the batter's head in relation to his shoulder during a swing; an audible sound device connected to the sensing mechanism to alert the batter when his head is not correctly positioned in relation to his shoulders during the swing; and an electrical power supply integrated with the sensing mechanism and said audible device and wherein said electrical power supply has sufficient voltage to activate the audible device.

Abstract: The present invention is concerned with a training device which can be worn by a user to teach the correct body position when hitting a baseball comprising: an adjustable sensing mechanism fitted on the batters helmet to sense the vertical movement of the batters's head in relation to his shoulder during a swing; an audible sound device connected to the sensing mechanism to alert the batter when his head is not correctly positioned in relation to his shoulders during the swing; and an electrical power supply integrated with the sensing mechanism and said audible device and wherein said electrical power supply has sufficient voltage to activate the audible device.

Abstract: A device for securing a catheter or like instrument to a patient comprises a first portion having an adhesive surface for securing that portion to the skin of a patient. A second portion is hingedly connected to the first portion and is adapted to fold thereover. The second portion has an adhesive surface to provide securement to the first portion when folded thereover. A slot and a hole are preferably associated with the first and second portions, respectively, for operably positioning the second portion around a catheter, which has been previously connected to the patient, so that the catheter extends through the plane formed by the second portion. This arrangement thereby facilitates the securement of the catheter in place on the patient.A method of securing a previously connected catheter or like instrument to a patient includes securing a device substantially as described above to a patient.
