Abstract: INJECTION MOLDING APPARATUS WITH IMPROVED COOLING     ABSTRACT OF THE DISCLOSURE      This invention cools the blowing mold and the plastic article blown therein to shorten the time that a core rod must remain at a blowing station of a blow molding machine for making plastic articles.  The cooling is performed by conditioned air that is dried to lower its dew point.  An air curtain is used to prevent other air from contacting with and depositing mositure on the mold.  In order to take advantage of the shorter time at the blowing station, an auxiliary injection device is used to also shorten the time required for the injection operation; and auxiliary cooling is supplied to the core rod at the stripper station.

Abstract: ABSTRACT OF THE DISCLOSURE           The specification describes an improved method and apparatus for measuring the density of an aerosol. The apparatus generally includes a housing containing a planar surface, whose resonant frequency is dependent upon a deposit of aerosol particles, and a metallic point whose axis is perpendicular to the planar surface.  The deposit of moving aerosol particles on the surface is normally caused by a high voltage electric current between the surface and point but rather than connecting the point to a negative terminal it is connected to a positive terminal.  This has been found to provide unexpected advantages and overcomes draw-backs of prior art devices as described in the specification.

Abstract: ABSTRACT OF THE DISCLOSURE           The tendency of a rounded tablet to rotate when travelling in an upright or erect position along an inclined transferring path and its tendency not to do so when the tablet is broken or specked, are advantageously utilized by the present invention for detecting flaws in tablet and for selecting the defective tablets from normal ones.  According to the present invention, transferring path bridging equipment in tablet processing lines comprises sloped parallel spaced rails having shoulders on sight opposed faces thereof and upper side plates above said shoulders.  The shoulders are capable of carrying the tablets thereon or therebetween and are sufficiently inclined such that an undamaged tablet rotates freely along the equipment while a defective or damaged tablet tends to stop along the path and block the tablets behind it.  The upper side plates permit unobstructed passage of the tablet in its erect position but inhibit or preclude travel along the path when it is in a reclined or fallen position.

Abstract: PROCESS CONTROL APPARATUS FOR CONTROLLING    A PARTICLEBOARD MANUFACTURING SYSTEM        Abstract of the Disclosure An improved particleboard manufacturing system wherein the weight of each mat for forming a particleboard is continuously monitored and controlled by a process controller as the mats are formed on a moving conveyor. The actual weight of each mat is determined and utilized by the process controller to selectively control the speed of the conveyor and the rate at which wood particles are deposited by a series of formed that are located along the conveyor system to thereby control the weight of mats currently being produced. The process controller includes a control system for continuously controlling mat weight by supplying former speed control signals that are related to a predicted weight error signal developed with the control system, and A measured weight error signal equal to the difference between a desired or target weight and the actual weight of each mat. A signal, equal to the difference between the measured error and the predicted error, is conditioned by a transfer function unit to supply a signal suitable for driving each former of the particleboard manufacturing system. To provide a nearoptimal control system, the signal conditioning supplied by the transfer function unit is adaptively in the process controller to provide automatic mat weight control whenever the system operator changes the production rate by altering the speed of the conveyor system. During such changes in production rate, this control system modifies the former speed based on changes in conveyor speed. A third control system contained within the process controller, permits the controlled particleboard manufacturing system to be efficiently changed form the production of one grade of particleboard to another grade whileminimizing the number of unacceptable mats that are produced. The process controller also includes a fourth control system that allows control controller particleboard manufacturing system to be reactivated after a brief interruption in production without producing a large number of mats of an unacceptable weight.
