Abstract: An infant seat (which is also called an infant carrier) includes a shell, a handle, and a spring. The handle has an arm hub coaxially aligned with, and rotatably attached to, a side hub of the shell. In one design, the side hub has notches, and the arm hub a projection. A spring has a longitudinal axis aligned substantially parallel to the hub axis and is positioned to radially bias the projection into engagement with a rotationally-aligned notch. The handle is movable in a direction substantially perpendicular to the hub axis to disengage the projection from the radially-aligned notch permitting the handle to be rotated to other notches corresponding to other handle positions. In another design, the arm hub has the notches, and the side hub has the projection.

Abstract: An isolation steam valve arrangement for use on the exhaust side of a steam urbine for directing exhaust steam therefrom to steam operated auxiliary equipment and for relieving or venting steam to the atmosphere. The valve arrangement includes a casing, or body provided with a single inlet and plural outlets. A main valve between the inlet and one of the outlets is selectively positionable from fully open to fully closed for controlling steam flow through one outlet for operating auxiliary equipment. A normally closed vent valve between the inlet and other outlet is adapted to open upon closure of the main valve to establish open communication between the inlet and other outlet in order to continuously vent to the atmosphere a low volume of steam from upstream of the main valve. A normally closed pressure operable relief valve is adapted to relieve to the atmosphere a high volume of pressurized steam from upstream of the main valve.

Abstract: A solar energy collector and heat exchanger assembly comprising a housing having a transparent top, a transparent wall within the housing parallel to the top to divide the housing into upper and lower chambers, the upper chamber having an air inlet and an air outlet, the lower chamber having a liquid inlet interconnected by a conduit to a liquid outlet, photo cells disposed in the lower chamber and adapted to provide heat to the conduit, and reflector structure disposed in the lower chamber for directing sunlight to the photo cells and for reflecting sunlight to the upper chamber.
