Abstract: An apparatus to selectively introduce a fluid from one of a plurality of containers into a stream of water flowing through a shower head. The apparatus comprises a housing, a main water passageway therethrough, a plurality of bottles containing fluid to be fed therefrom, supplemental passageways coupling the bottles and the main water passageway whereby fluid from the container may flow to the main passageway by venturi forces created by flowing water, a valve mechanism means movable between open and closed positions by the venturi forces to allow or preclude the feeding of fluid to the flow of water, and user controlled means to selectively allow the valve mechanism to be coupled with the venturi force. Also disclosed is the method for selectively introducing a fluid from a container into a stream of water flowing through a shower head by venturi forces of the flowing water.

Abstract: A speed reducing device for use from a fishing boat when fishing in a boat moving with the wind and/or a current comprising a rearward portion formed as an essentially circular end panel of water impervious material having the buoyancy to float in water; an intermediate portion formed of a plurality of similarly shaped mesh panels adapted to allow the flow of water therethrough while precluding the passage of debris into the device, each panel having a generally triangular configuration with a rearward edge and side edges converging and meeting at the forwardmost position, the panels being stitched together along the side edges into the general configuration of a cone with the small end of the cone constituting the forward end of the device and with the large end of the cone constituting the rearward end of the device, the end panel being stitched along its periphery to the rearward end of the mesh panels; and a forward portion being formed by the folded midpoints of cords jointly coupled together at the smal

Abstract: A device for condensing steam, the device including a bundle of long heat-exchange tubes extending from first and lower header means to second and upper header means defining paths for the steam as it moves from the lower header means toward the upper header means and for effecting a flow of steam upwardly and a flow of steam condensate downwardly within the tubes, and new baffling installed inside some of the tubes of the bundle to channel and separate the upward bulk flow of stream and the downward bulk flow of condensate so as to prevent interaction between the two fluids that disrupts normal flow and heat transfer.

Abstract: An improved compression hip screw system including a lag screw having a first end with external threads insertable into the proximal end of a femur head and broken fragments thereof and having a second end with an axial bore; a barrel/side plate having a plate-like member attachable at its distal end to a femur and having a barrel at its proximal end for receiving the second end of the lag screw; a compression screw within the barrel and extending into the bore of the lag screw, a supplemental set screw threaded through the barrel/side plate to secure the compression screw in a fixed position with respect to the barrel/side plate; and a coupling device joining the lag screw and compression screw to allow a telescoping motion between the lag screw and the compression screw in the event of axial movement of the broken fragment and lag screw with respect to the proximal end of the femur and the barrel/side plate.
