Abstract: A dental implant unit includes a layer of synthetically created titanium dioxide. The dental implant unit has one end for connection and a lateral surface covering the implant unit except for the end for connection. The lateral surface includes a layer of synthetically created titanium dioxide while the end for connection is free from synthetically created titanium dioxide. Also, a method produces a whitened implantable dental unit. The method includes thermal oxidation of a dental implant unit that includes titanium.

Abstract: The present invention describes a medical device comprising a set of particles of titanium oxide, wherein at least a substantial amount of the particles are of micrometer—millimeter size, and wherein at least 10 wt % of the titanium oxide is in the amorphous form.

Abstract: The present invention describes particles of titanium, titanium alloy, at least one type of titanium oxide or a combination thereof, wherein at least a substantial amount of the particles are of micrometer-millimeter size and are non-spherical, for use as an X-ray contrast agent. The irregular shapes and/or internal pores and cavities of said particles lead to a prolonged retention time in the gastrointestinal tract leading to a longer time period available for X-ray examination. Further, the particles are not only chemically inert, they also exhibit an anti-inflammatory and anti-bacterial effect on the surrounding tissue.

Abstract: A method for hemoglobin determination is described which includes the steps of introducing a sample of undiluted whole blood by capillary action into a disposable microcuvette having at least one cavity for receiving the sample. The cavity includes a dry essentially non-hygroscopic hemolysing agent, which is dissolved by the blood, hemolyses the red blood cells and releases the haemoglobin contained in the blood cells. A first absorption measurement at a wavelength range 490-520 nm is then performed directly on the sample in the microcuvette, and a second absorption measurement is performed to compensate for background interference.

Abstract: A method is provided for monitoring the cooking temperature of meat patties. More specifically, a method is provided for monitoring the cooking temperature of meat patties by determining the concentration of colored compounds, such as myoglobin, in meat juice.

Abstract: A switching device (5) is arranged in a junction element (1), which is to be used in a toy railway and is in the form of a reversible plate. On each flat side, this plate is formed with depressions (2, 2', 2"), which in pairs form an incoming railway track (2) and two outgoing railway tracks (2', 2") extending therefrom. On each flat side, the switching device (5) has a switch plate (6) which is arranged in a recess (7) formed in the respective flat sides and which is pivotable between a first position and a second position, in which it produces a track connection between the incoming railway track (2) and the one or the other of the outgoing railway tracks (2', 2"). The switch plates (6) are interconnected by means of a connecting element (12), which extends through a profile hole (16) in the junction element (1) and which, when the switch plates (6) occupy the first and the second position, engages a first and a second portion (16', 16"), respectively, of a wall delimiting the profile hole (16).

Abstract: The present invention is related to an integral capillary microcuvette comprising a body member and a cavity including a measuring zone within the body member. The cavity is defined by two opposite, substantially parallel inner surfaces of the body member and includes an outer peripheral edge comprising a sample inlet and an inner peripheral zone having a channel of higher capillary force than the measuring zone. The channel extends around the entire inner peripheral zone with ends of the channel communicating with the atmosphere at the exterior of the microcuvette.

Abstract: The present invention is a cuvette provided with at least two cavities. The first or inlet cavity takes up fluid by capillary action. The second cavity is a reception cavity which communicates with the first cavity through a first channel. The second cavity preferably is constructed and arranged to not exert a capillary action, although it could be constructed to exert a capillary action. The first channel which is in fluid communication with the first cavity and the second cavity exerts a non-capillary and non-spontaneous fluid transporting function that is operative only under an external influence, such as by application of a centrifugal force on the cuvette. The cuvette is well suited for a variety of analyses, particularly upon whole blood.

Abstract: A device for rapidly performing a sedimentation-rate test is described. A tube (17) containing a given amount of blood specimen is placed in a holder (13, 21, 22) which rotates (23) the tube (17) a predetermined number of revolutions at a given speed about an axis perpendicular to the longitudinal axis of the tube while rotating (24) the tube about its longitudinal axis, to then stop the tube for a given period of time about 60.degree. from the vertical, and to finally turn the tube (17) to the vertical position at a speed which is but a fraction of the first-mentioned speed also while turning the tube about the longitudinal axis. Means (26) are arranged to monitor the rotational movements of the tube, preferably by means of markings on a plug (18) closing the tube end.

Abstract: A cuvette for taking up a fluid and mixing the fluid with a reagent for analyzing the mixture consists of a body (10) of glass or polymeric material having a first cavity (12) in which the fluid can be taken up, preferably by capillary action, through an inlet (13), and at least one further cavity (21) exerting capillary force on fluid which is transported from the first cavity (12) into a reception cavity (17) by subjecting the cuvette to centrifugal force. The further cavity (21) preferably exerts capillary force through a wick (19) which does not extend as far as the bottom of the reception cavity (17), and a capillary channel (20). In those cases where more than one further cavity (21) is provided, each such cavity (21) communicates with a further reception cavity into which the fluid can be transported from the cavity (21) by the exertion of centrifugal force. The cuvette may also have cavities for receiving washing or diluting liquid, which are connected in series or in parallel with the cavity (12).

Abstract: A device for self-administration of physiologically active substances without the occurrence of overdosing, includes a container accommodating at least one substance and propellant means for propelling the substances out of the container, nozzle means connected to the container for discharging a substance, a valve connected between the nozzle and the container such that a predetermined amount of the substance is propelled from the container each time the valve has been opened, and manually activated electronic control means for opening the valve in response to manual activation of the electronic control means and for preventing opening of the valve greater than a predetermined number of times within a predetermined time period.
