Abstract: Apparatus for administering a liquid formulation to a baby or child includes a bottle charged with water, a dispensing valve mounted on the bottle, and a dust cover that extends over and protects the dispensing valve. The dust cover is hollow and is charged with powder that is mixed with water in the bottle to produce the liquid formulation.

Abstract: A rotisserie cradle including a trough shaped cradle constructed entirely of a rod framework to be lighter, easier to clean, and cheaper to manufacture, with food hold down grates positionable by swing arms pivoted to the inside of the cradle framework so as to allow manually settable positioning of the grates against the food to hold the same against the inside of the cradle framework. Each hold down grate is tiltable in any direction to engage any contour of the food to be held, and the swing arm movement accommodates different sized food items. Friction snubbers can be used to maintain the swing arm positions. A pair of socket blocks for receiving the rotational support shafts are mounted by the rod members forming the cradle framework.

Abstract: A heat sink and method of manufacture is described. In the preferred embodiment, an array of tubes are extruded from a block of conductive metal, such as aluminum. A series of plugs or pins are extruded in a first stage, and the plugs are reverse extruded by tooling pins to form tubes of considerable or varying length, integral with the base plate. The tube closed ends are punched so as to form holes through the base plate which has a groove crossing pattern aligned with the holes to provide an air convection flow path. The tubes may be assembled to a base plate as separate elements, and a channel member can also be utilized to provide flow passages extending to each tube.

Abstract: A differential pressure indicator is disclosed, providing an indication upon detection of a predetermined level of differential pressure in a fluid pressure system. The device includes a piston mounted to a rolling lip diaphragm, with the differential pressure exerted across the piston, which is thereby moved against the resistance of a bias spring from a non-display position to a display position upon development of the predetermined differential pressure. The piston is viewable in the display position through a 360.degree. window formed integrally with the housing or by a separate transparent ring assembled into the housing. Valving may also be controlled by the piston movement, enabling communication of fluid pressure to an outlet port for activation of a fluid pressure operated audible signal or other indicator device.
