    Abstract: The apparatus comprises a turntable carrying, in a circular array centered on a central rotational axis of the turntable, a plurality of vials extending below the underside of the turntable. A stepper motor imparts stepwise rotational motion to the turntable so that during dwell periods of the turntable, specimens in the vials can be investigated optically.Air in a space below the turntable and bounded laterally and at the bottom by an enclosure is circulated by a rotating vane, and a thermistor, responsive to the temperature in the region of the vials, controls a heater in the space below the turntable so as to maintain the temperature of the vials substantially at a predetermined value.In order to dispense liquids into the vessels at predetermined temperatures, the apparatus additionally includes a liquid dispenser mounted adjacent the turntable and comprising a tubular body with an electric heating coil and a dispensing device which dispenses liquid from the outlet of the tubular body in predetermined quantities, the heating coil being supplied with the necessary quantity of power to maintain the temperature of the dispensed liquid substantially at a predetermined value.Preferably, the apparatus is used for analysing blood specimens.

    Abstract: A Cassegrain-type concentrating solar collector cell includes primary and secondary mirrors disposed on opposing convex and concave surfaces of a light-transparent (e.g., glass) optical element. Light enters an aperture surface surrounding the secondary mirror, and is reflected by the primary mirror and the secondary mirror onto a photovoltaic cell, which is disposed in a central cavity formed in the optical element. A resilient, optically transmissive material is disposed in the central cavity between the PV cell and the optical element. The photovoltaic cell has a squarish upper surface including metal electrical contact structures disposed on each of the four corners of the upper surface and arranged to define a circular active area. The PV cell is mounted on a heat slug that is disposed in the central cavity during assembly. The heat slug includes resilient fingers that contact the surface of the cavity to facilitate self-alignment of the PV cell.

    Abstract: A flexible media transport system includes a director element having articulating tips that provide access to selected media paths. The director element(s) can be incorporated into a director module. Multiple director modules can then be combined into a highly flexible and reconfigurable media transport system. By implementing the joints between the articulating tips and the body of the director element such that a continuous surface is provided in the path of the flexible media, stubbing of the moving media can be avoided. The continuous-surface joint interface can be provided via flexible skins, monolithic articulating tip-director element structures, and preconfigured resilient plate structures, among others.
