IPC: G01N33/557
Filed: 1992-07-28
Abstract: ABSTRACT OF THE DISCLOSURE    A specific binding assay process which is useful for quick qualitative or quantitative measurement and can be used for various purposes, and a specific binding assay device suitable for the practice of the process, in which a substance to be assayed in a liquid test sample is determined qualitatively or quantitatively by developing the substance in a liquid test sample in a matrix, which comprises the steps of for example: allowing the substance to be assayed to react with a specific binding substance which has specific affinity for the substance to be assayed; allowing a signal substance generator (a substance which competes with the substance to be assayed for the specific binding substance and which generates a signal) to change its distribution in the matrix in response to the reaction of the above step, and; detecting resulting distributional changes at a detection means as changes of signals which are rate-limited by the mass transfer of a signal substance generated from the signal substance generator.

Abstract: A swinging drawbar (32) is provided for a driven device, in particular for an agricultural vehicle or utility vehicle, in which drawbar (32) the coupling point can be adjusted to at least two different working lengths. In order to permit simple adjustment to different working lengths and to permit the coupling point to be conveniently seen from the driver's seat during the coupling process, optional locking means (86, 88, 110) which correspond to the different working lengths are attached at positions (78, 80, 82, 84) in such a way that during the longitudinal displacement of the swinging drawbar (32) automatic locking takes place when the selected working length is achieved. Preferably, a cartridge (22) is used which can be attached to the vehicle, and has transverse grooves (110) and into which the swinging drawbar (32) can be inserted. Locking noses (102, 104) which are formed onto claws (86, 88) engage in the transverse grooves (110). The claws (86, 88) can be mounted at different positions of the swinging drawbar (32).

Abstract: A method of seasoning lumber without the occurrence of cracks or warps by raising the turnover ratio of the dryer. In the first step, the lumber is placed into a pressure vessel, and after unifying the temperature within the lumber by charging and discharging of saturated steam in the vessel and fluctuating the steam pressure for pressurizing, the saturated steam maintaining the unified temperature in the vessel is discharged, and by boiling and evaporating the water contained in every tissue of the lumber, it is formed into a state that can be seasoned uniformly. Secondly, the lumber is seasoned by discharging the free water contained in the lumber removed from the pressure vessel. Thirdly, the lumber of which free water is evaporated is placed back into the pressure vessel, and by forming the current of the superheated steam within the vessel, the lumber is pressurized and heated, thus eliminating the contained water.          The invention provides no moisture content gradient and no tendency to form moisture content gradient in the lumber.

IPC: A61M16/04
Filed: 1992-12-21
Abstract: A laryngeal mask has an inflatable ring configured, upon inflation, to establish a peripheral seal around a patient's laryngeal inlet.  Installation (insertion) is made in the fully deflated state, wherein the structural relation between the body of the mask and the inflatable ring is such that deflated ring surfaces become tightly opposed to each other so as to form a thin flange which peripherally surrounds the body of the mask and is concave on the posterior side of the mask; the concave flange effectively displaces all ring material away from the aperture of the mask, in the manner of the upturned brim of a hat.  The concave flange is softly yieldable in its confinement by local body structures encountered in the course of mask insertion.  And it is an important feature that the distal end of the deflated ring is adapted not only to smoothly ride posterior contours of the throat and pharynx but also to gently cam the epiglottis out of the path of insertial displacement of the mask while also assuring that the distal end of the deflated mask smoothly enters the upper sphinctral region of the oesophagus.  Once thus insertionally located, ring inflation will assuredly establish the desired peripheral seal of the mask around the laryngeal inlet.
