Abstract: An air return system for a rotatable rack baking oven having a heat source and a blower associated therewith for providing a flow of heated air across a baking chamber of the oven. The outlet end of the blower is connected via ductwork to an air outlet vent which introduces the heated air into the baking chamber. The air outlet vent includes a lattice of fixed vanes which are elongated in the direction of intended air flow. This arrangement channels the heated air to exit normal to the outlet vent to maintain a well defined column of air with less turbulence. An air return vent is located opposite the air inlet vent and is operatively associated with the heating means and the inlet side of the blower. The air return vent includes a panel having a plurality of holes through which the air may be drawn. A number of return holes in the return vent are blocked such that their numbers vary in inverse proportion to the drawing force produced by the inlet of the blower.

Abstract: The invention concerns a process for regulating a respiratory apparatus and the respiratory apparatus itself. The apparatus permits a succession of respiratory cycles depending on patient requirements, such as frequency FR (or respiratory rate RR). The succession of respiratory cycles consists of an inspiration phase, during which the patient is supplied with a current tidal volume (VT) of respirable gaseous fluid, and an expiration phase. The patient has his/her own natural spontaneous respiration, and the pressure in the patient's respiratory passages is defined as Paw. According to the the process, a theoretical respiration volume per minute value, called Vmn optical, is established as a function of the patient's condition and natural spontaneous respiration. Other values are also set or calculated. A minimum current tidal volume (VTmin) and a maximum allowable airway passage pressure, Paw max, are established.

Abstract: In an ophthalmological measurement method and apparatus, a laser beam of predetermined diameter is projected to the eye fundus and movement of a speckle pattern formed by light scattered by blood cells in blood vessel is detected by a photosensor as fluctuation in speckle light intensity to produce a speckle signal. The speckle light intensity will fluctuate more rapidly with a smaller output from the photosensor when cell velocities are high, while a low cell travel speed will decrease the lowering of the output therefrom. The speckle signal thus mirrors the travel speed of the blood cells in the eye tissues. The differences in the speckle signal are used to identify the blood vessel for automatic tracking of the blood vessel or for measurement of its diameter.

Abstract: A blender designed on aerodynamic principles produces a thorough mixing of a number of solute gases with a diluent gas, so that the output of the blender is homogeneous to a high degree. The solute gases are supplied at desired rates by a flow controller upstream of the blender, and the blender is designed to mix these solute gases without altering the desired composition. This is accomplished by discharging the solute gases into a region devoid of turbulence, namely, near the entrance of a compression chamber. As the discharged gases approach the constriction of the venturi, a violent turbulence takes place, thereby thoroughly mixing and blending the gases. After passing through the constriction of the venturi, the gases enter a second expansion chamber which slows the flow to permit further blending to occur by molecular diffusion.

Abstract: A system and method for selecting one of a plurality of liquid supply receptacles as a source of supply for a liquid dispensing apparatus is disclosed. As liquid is withdrawn from the supply receptacle the dielectric constant of the liquid is sensed in order to detect any undissolved gases (i.e., bubbles) which are present in the liquid. The presence of bubbles within the liquid indicates that a supply receptacle has become empty or indicates a failure of components associated with one of the supply receptacles. Upon the detection of undissolved gases within the liquid withdrawn from a supply receptacle, the present invention causes another liquid supply receptacle to be selected as a source of supply for the liquid dispensing apparatus.
