IPC: B27N3/14
Filed: 1979-06-15
Abstract: A method for supplying a liquid to a mat (11) of wood particles to be pressed to boards and a device for carrying out the method. Finely divided liquid, e.g. water or a wax dispersion, is supplied to the mat (11) synchronous with the deposition of wood particles from the forming station (10). The same amount of liquid per unit of surface of the mat will be supplied as the liquid is fed to the mat (11) synchronous with the deposition of wood particles from the forming station (10). A device for carrying out the process comprises a forming station (10), equipped with nozzles (17a, 17b)for liquid and outlet means, which are arranged in such a manner, that liquid will be fed from the nozzles (17a, 17b) simultaneously with the operation of the forming station (10).

Abstract: The PN juncture in a silicon chip and an oxide coating on its surface are simultaneously formed from clear solution derived from titanium alkoxides, water, alcohol, a suitable acid, and a P or N dopant by partial hydrolysis and polymerization. The solution is applied to the surface of a silicon chip. The chip is then heated which converts the solution to a solid oxide coating which meets the antireflective optical film requirements and induces the migration of the dopants into the chip, forming a PN junction in the chip. The method also provides deep and uniform junction formation or diffusion without resulting in excessive carrier concentration.

Abstract: A method and apparatus is provided for injection molding a closed tubular parison while rotating an injection molding surface and then transferring the still warm parison to a blow mold and blowing the parison to form a finished article, such as a bottle. The apparatus comprises a first platen (19) having at least one core pin (86) mounted thereon and laterally and axially movable relative to corresponding injection molding cavity (172) and a blow molding cavity (12) associated with a second platen (236). The surfaces of the core pin member (86) and injection molding cavity (172) are made relatively rotatable so that injection molding of the parison imparts longitudinal and transverse orientation to the parison, various layers of material being axially differently oriented. The pin (86) and cavity (172) are cooled to more rapidly form the parison The parison, still on the core pin 1186), isthen transferred to the blow molding cavity, and, after a penod of time for the parison temperature to equilibrate through the parison wall, is blow molded through a central passage (118) in the core pin to form a finished article. The present apparatus may comprise an array of core pins displaceable between corresponding injection molding and blow molding cavities and may further comprise improved core pin valve means (20) for releasing blow pressure prior to pin disengagement; secondary pin cooling (108), to insure axially uniform pin cooling; pin coolant cycling to prevent parison cooling below a suitable blow molding temperature rotatable bearing and sealing means (26) for sealing the pin relative to the injection cavity; and a fluid polymer passage for directing fluid polymer under injection pressure into the rotating cavity. The presently preferred method includes injecting and rotating at maximum rates to maximize orientation, and blow molding to a stretch ratio of less than 4:1 to produce small articles.

Abstract: Although carbonic anhydrase inhibitors (C.A.I.) can be administered systemically by oral or intravenous routes, attempts to administer them topically have been ineffective and inactive in the treatment of intraocular hypertension. The alkali metal salts, especially the sodium and potassium salts, of salt-forming C.A.I. are now found to be remarkably effective in lowering intraocular pressure, even in normotensive hosts, but especially in those hosts having an elevated intraocular pressure.

Abstract: in a digital speech detector, a first detector (601) produces an output signal if any sample of a voice channel signal has a magnitude (T) exceeding a fixed threshold (TF) above noise levels. A second detector (602) produces a second threshold (TL) which is adaptively adjusted to noise levels on the channel by being set to a level above the current sample magnitude (T) each time that this does not exceed the preceding sample's magnitude (TP). When the sample magnitude (T) rises above the second threshold (TL), and for each subsequent sample of successively increasing magnitude, the second detector (602) produces an output signal. A speech decision for the voice channel is reached if either detector (601, 602) produces its output signal. The output signals of the first and second detectors (601, 602) are maintained for fixed and variable, respectively, hangover periods to maintain the speech decision during intersyllabic pauses in speech. The samples are supplied to the speech detector by an offset remover and averaging circuit.

Abstract: System for the remote measurement of the relative speeds within a moving fluid, in particular water and air and comprising:   - an emission of acoustic wavetrains along at least one specified direction   - a reception of the waves diffused in particular by the turbulence remote from the emission    - a measurement of the frequency of the waves received   - a determination of the frequency deviation, equal to the difference of the emitted and received frequencies   - an evaluation of the velocity component of the fluid by the DOPPLER formula. The determination of the value of the real Doppler component is undertaken by a global frequency measurement in a so-called "working" pass band substantially centred on the emission frequency and by a simultaneous estimate of the ratio between the powers of the background noise and of the useful signal which are sensed; this permits this global measurement to be corrected. <IMAGE>
