Abstract: TITLE OF THE INVENTION            SYSTEM FOR DISPENSING CURABLE COMPOSITIONS                 ABSTRACT OF THE DISCLOSURE        A system is provided for dispensing curable compositions formed by a mixture of first and second materials which, when mixed in prescribed ratio, interact with each other to provide a relatively rapidly curable composition, such as a polymerizable epoxy resin or the like.  The materials are individually pumped and metered through a first mixer and a dispensing valve to a dispensing nozzle. During start-up, the dispensing nozzle is closed, and the initial mixed composition is diverted through a bypass valve for dilution and mixture with a diluent stream of the first material in a second mixer and for return of the diluted mixture to the supply reservoir of the first material.  When a homogeneous mixture of prescribed ratio is achieved at the outlet of the first mixer, the bypass valve is closed and the dispensing valve can be opened to allow dispensing of the composition.  Upon shut-down, supply of the second material to the first mixer is ceased, and the dispensing valve and bypass valve are closed and opened, respectively, the first material is supplied to the first mixer and through the bypass valve to flush the composition therefrom and for dilution of the composition with the diluent stream in the second mixer.

Abstract: ABSTRACT OF THE DISCLOSURE         This invention relates to a valve gated injection molding system of the type where the melt passage enters the system on general alignment with the valve pin and cavity.  The system has a novel valve pin actuating mechanism which is pneumatically operated according to a predetermined timed cycle.          A piston which  reciprocates in a cylinder has an outer collar portion from which a tongue portion extends inwardly to operatively engage the driven end of the valve pin.  The melt passage extends through a portion of the back plate which, in turn, extends through the outer collar portion of the piston and is offset to leave room for the tongue portion of the piston to engage the driven end of the valve pin.  Piston rings are located between the piston, back plate and cylinder to prevent excessive air leakage.  This center entry system with a pneumatic actuating mechanism provides a more reliable mechanism which may be double acting.

Abstract: ABSTRACT    I have conceived of a wire puzzle made of four interlocking members, two members being essentially identical the other two members being unique.  Each is formed from its own length of wire rod.  My novel puzzle was adapted to allow one of the members to be threadingly engaged and disengaged from the other three members while maintaining all members rigid.  This task, when unknown, is perplexing.

Abstract: VIDEO DISPLAY RECORDING APPARATUS              Abstract Of The Disclosure Apparatus for recording a displayed frame of video data by storing the binary data bits from identical segments of each video scan line, thereafter supplying the stored bits of the segments to a traversing matrix print head for recording the bits in those segments, and repeating the process with data bits from a different series of scan line segments.  The number of data bits comprising a segment usually corresponds to the number of recording elements in the print head, and the number of print head excursions will vary inversely to the number of data bits in each segment.  A resulting recorded video frame thus appears rotated 90° with respect to the original frame orientation.

Abstract: ABSTRACT OF THE DISCLOSURE           In displaying on a viewing screen an image generated by output signals from a radiation-sensitive detector, e.g., an infrared detector, it may occur that weakly contrasting details in the image are lost when the light intensity of the image covers too great  an intensity range.  In one method of avoiding this loss of details, the amplification of the low-frequency por-tions of the video signals is regulated adaptively by calculat-ing two statistical parameters, characteristic for the statisti-cal properties of the signal values, and adjusting the amplifica-tion such that a selected image intensity corresponds to the calculated parameters.

Abstract: ABSTRACT            The invention relates to a method of recovering chemicals from chloride-containing green liquor by precarbonating the green liquor by means of flue gases into hydrosulfide and soda, by removing hydrosulfide from the precarbonated solution in the form of hydrogen sulfide, by evaporation crystallizing the chloride- and soda-containing solution in order to separate the soda in crystalline form, and by causticizing and evaporation crystallizing the chloride-containing solution in order to separate the chloride salt from the alkaline solution. In order to reduce releases of hydrogen sulfide, the produced hydrogen sulfide is absorbed into a soda solution and/or an alkaline solution in order to produce a solution suitable for the preparation of white liquor, whereas the hydrogen sulfide which remains unabsorbed is returned to the precarbonation stage, in which the hydrogen sulfide is absorbed substantially completely. By means of the invention it is possible to achieve a closed cycle of chemicals without the chloride load of the system increasing, and at the same time the chloride is recovered and returned to the bleaching.

Abstract: ABSTRACT      A metal from group IVb of the periodic table is used as the target in a reactive deposition process.  An inert gas such as argon is admitted within the chamber (12)  housing the target  (21)   Electrical power at a constant level is supplied to the target, ionizing the inert gas so that the ions bombard the metal target and initiate sputtering.   A controlled flow of a reactive gas such as nitrogen is then admitted to the chamber and controlled in such a way that the metal deposition rate is not lowered. The amount of the reactive gas  is constantly sampled to provide a control signal used to regulate admission of the reactive gas at the proper rate for most effective deposition of the metal onto the substrate.  Closed loop systems (45,29,31,43,44, 26,27, 39,62) regulate the level of electrical power supplied to the target, rate of admission of the inert gas, and rate of admission of the reactive gas.

Abstract: ABSTRACT:     "CAST CONCRETE ELEMENT FOR UNDERGROUND TUBULAR                     STRUCTURE"     A modular cast concrete element capable of being assembled with other, similar elements into a tubular underground installation (e.g. sewer duct, tunnel liner) has a well opening to each of its axially-facing end surfaces wherein a rod is received that is insertable in a like well in an axially adjacent element to guide one of the elements to a predetermined position relative to the other and lock it in that position. In each well is a tubular retainer containing a securement member having an annular radially outer marginal portion confined in a circumferential radially inwardly opening groove in the retainer  and having resilient radially inwardly projecting teeth. The teeth have radially inner edges on a circle of smaller diameter than the rod and are flexible axially to enable the rod to be easily inserted into the securement member but to engage it under convergent bias for holding it against withdrawal from the well. Each  retainer can be assembled from commercial plastic pipe fittings or may be formed from injection mouldings.
