Abstract: The invention relates to a control system for adjusting the setting of a damper (9) in a ventilation duct (8) and maintaining a substantially constant pressure at a selected region in the ventilation duct, the system com­prising a cylinder (1) having a vertical cylinder axis and housing a readily movable, pressure-responsive device (2), which together with the cylinder defines a pressure space. The pressure space (22) communicates with the ventilation duct at the aforementioned selected region, and drive means (11, 12) are provided for adjusting the damper setting in response to the position of the pres­sure-responsive device, so as to maintain a constant pressure. The inventive system is characterized in that the pressure-sensitive device (2) has a mass which cor­responds to a selected pressure at the aforementioned region in the duct and is intended to balance the pres­sure force acting on the device.

Abstract: Borate crosslinking of hydrated galactomannan gums in fracturing fluids is delayed by adjusting the release of particulate basic material which is slurried in a hydrophobic carrier. The hydrophobic carrier containing base and a surfactant is dispersed into an aqueous, acidic mixture of the galactomannan gum and a borate-releasing compound. The surfactant effects the slow release of particulate basic material from the hydrophobic slurry thereby gradually raising the pH, allowing time for hydration of the gum prior to activation of the borate crosslinking in the solution when it reaches a basic pH.

Abstract: A method for defining an array of light-emitting pixels in a thin film electroluminescent edge emitter structure includes the steps of moving the structure in proximity to a stationary first laser source as the first laser source is operated to generate a plurality of first laser pulses. The plurality of first laser pulses are focused into "lines" of light energy that strike the structure at a plurality of spaced apart locations in succession to ablate a predetermined number of layers of the structure. This ablation process forms a plurality of spaced apart channels in the structure. The portions of the structure remaining between each pair of adjacent channels define an array of pixels in the structure. The structure having the pixels formed therein is moved in proximity to a second laser source. The second laser source is movable in a selected direction substantially perpendicular to the direction of movement of the struc­ture. The second laser source provides a second laser beam that is focused to a "point" of light energy which strikes the end portion of each pixel at an area inward of the pixel edge surface to ablate a predetermined number of layers at each pixel end portion. The movement of the second laser beam is controlled relative to the movement of the structure to correspondingly control the amount of material ablated inward of the edge surface of each pixel to remove the pixel edge surface and form a new pixel edge surface shaped to a preselected contour.

Abstract: In a method for reading optical information items picture element by picture element, picture sensor elements connected in parallel to a common read-out circuit are successively exposed to the picture element information items to be detected by them, in which arrangement in each case the photocurrents of all picture sensor elements are detected as sum signal by means of the read-out circuit. The sum signal contains the illumination current of the picture sensor element in each case exposed as useful signal component and the sum of all dark currents of the remaining unexposed picture sensor elements as noise component, so that the signal/noise ratio becomes worse with an increasing number of picture sensor elements. To improve the signal/noise ratio, photodiodes (23) are used as picture sensor elements and the open-circuit voltage common to them is detected as evaluatable signal by means of the read-out circuit (25). <IMAGE>

Abstract: A test instrument for uniformly spreading a collected specimen on a reagent layer has a first opening for collecting the specimen, a specimen spreading layer having an upper surface a portion of which is exposed to the first opening, the reagent layer provided so that an upper surface thereof is in contact with the lower surface of the specimen spreading layer, and a support layer provided on a lower surface of the reagent layer. Even if the specimen does not attached itself in a uniform distribution over the large area of the first opening, it will be evenly distributed at the second opening, the opening area of which is smaller than that of the first opening at which measurement is performed. When an adsorbing layer provided in the proximity of the edge portion of the first opening is supplied with an excess amount of the specimen, a direct path to the adsorbing layer is blocked by the inner peripheral region of the first opening so that the adsorbing layer is soaked via the spreading layer. Consequently, the specimen is distributed on the reagent layer uniformly and at a fixed concentration irrespective of the amount thereof.
