Abstract: An automated food-fryer system is configured to automatically move a food-fryer basket (4) from a food dispense (1)r to a cooking well (3) and then to a food dump (5); the system includes a basket transport system (2) that is made up of several, separate transport modules that are configured to automatically move baskets (4), and in which the movements (i) between the food dispenser (1) to the cooking well (3) and (ii) down into and up from a cooking well (3), are independent of, or asynchronous from, each other.

Abstract: A therapeutic level medical gas delivery system includes a pressure regulator with a control point for a flow of medical gas through a critical flow orifice; a variable flow restrictor; and a mixing chamber for the combination of fixed flows.

Abstract: A delivery system utilizing a diffusion membrane that regulates the concentration of medical gases that are administered to a patient. A storage vessel contains a neat or pure medical gas under pressure that is in fluid communication with a diffusion membrane. The medical gas is then dispensed at a specified rate by diffusion across a membrane into a carrier gas. The concentration is kept constant by regulating the pressure and carrier gas flow. Typical applications are for inhaled gases that are used in patient treatment and care.

Abstract: Systems and methods are disclosed for generating a gas at therapeutic levels to a subject by providing a pellet dispenser that delivers a predetermined amount of thermally labile compound to a furnace; controlling a rate of compound addition to allow controlled continuous evolution of the gas; and maintaining a predetermined concentration of the gas using temperature and dilution with an inert gas.

Abstract: The present invention relates to methods and apparatus useful for detecting and measuring flow of a fluid along a flow path. In a method according to the invention, the temperature of a flowing fluid is altered at a selected location for a selected duration so as to generate a pulse in the fluid moving in a downstream direction along a flow path, and the fluid is monitored at a sensing region to detect the pulse passing therethrough. An apparatus according to the present invention may comprise a conduit, a sensor element disposed therein, an energy source proximate to the conduit, and a controller operative to generate an on signal and an off signal respectively operative to activate and deactivate the energy source. The present invention also relates to a liquid chromatography device having a fluid flow detecting and measuring apparatus according to the present invention.

Abstract: This present invention relates to a ratchet wrench and a torque indicator combined concentrically in a single housing. The ratchet wrench is useful for driving a fastener used in dentistry, such as an abutment screw that holds an abutment on a dental implant. In operation, the handle of the wrench can be rotated in one direction (e.g. clockwise) to impart torque on the fastener. When the handle is rotated in the opposite direction (e.g. counterclockwise), no torque is applied to the fastener as the handle is returned to a position where it is easy for the clinician to again rotate the handle to apply additional torque to the fastener. The return motion of the handle (e.g. counterclockwise rotation) may be stepless in operation which is brought about through a coiled clutch spring located in an annular space within a housing between the housing and a concentric driver member. To provide an indication of torque, a rotor body is supported coaxially within the driver member.

Abstract: A method and apparatus for measuring optical properties of materials such as optical rotation, depolarization and absorption includes a light source emitting a primary beam of light that is monochromatic, collimated and plane-polarized and a sample cell through which this beam is passed. The primary beam is split into at least two components by a beam splitter and each component is passed through an analyzer, such as a prism. The two analyzers have polarizing axes oriented at a non-zero angle with respect to one another and at pre-selected angles with respect to the plane of polarization of the original beam. Signals corresponding to the intensities of the components are produced by detectors and then the signals are amplified, digitalized and processed to yield the optical properties. A third test component may alternately be split from the primary beam after it has been passed through the sample with this test component also being detected and processed.
