Abstract: ABSTRACT OF THE DISCLOSURE         When burning black liquor obtained during cellulose pulp manufacture it is desirable to maintain a constant atomizing pressure.  Mere throttling of the liquor supply in order to adjust the combustion to actual heat demand will alter the spray pattern.  A pressurized gaseous fluid is injected into the liquor supply conduit, and the amount of this gaseous fluid is governed in response to the actual heat demand.  A monitoring device senses the pressure in the supply conduit downstream of the throttle valve, and adjusts the position of the latter in response to the activity caused by the gaseous fluid, so the resulting pressure is maintained at the desired level.

Abstract: DUSTLESS ROUTER     Abstract of the Disclosure.  A dustless portable electric router comprising a base having a dust chamber formed below a motor mounted to the base to be axially adjustable there-in.  A pair of handles are connected to the base with a passage formed in one of the handles in communication with the dust chamber.  A blower is formed on the top side of the motor with the router connected to and driven by an ex-tension from the motor armature shaft.  A flexible conduit interconnects the handle passage and the blower, and a dust bag collects the dust and debris from the blower discharge.    The dust chamber has side openings which are enclosed by detachably connected plastic shrouds that provide opera-tor visibility.  A light is connected in the other handle and serves to illuminate the dust chamber and the surrounding work.  The dust bag is hung from the blower at the "back" of the router housing, and the blower is positioned remote from the work engaging flat bottom of the router base.  The conduit which interconnects the handle and blower is flexible to per-mit axial adjustment of the motor within the base.

Abstract: ABSTRACT OF THE DISCLOSURE        A transmission line is established between two distant points utilizing a pair of pipelines, one of which is insert-able within the other.  The outer or larger diameter pipe-line is first installed or laid between the two distant points and the pipe is filled with a suitable high density lubricating liquid.  The other pipeline which carries and houses the transmission line is initially filled with an inert gas and in this condition the pipeline and trans-mission line are "floated" into and through the outer pipeline.  After both the inner pipeline and transmission line are in place inside the outer pipeline, the high density lubricating liquid between the pipes may be removed and substituted with a high thermal-conducting non-polluting fluid.  The inert gas within the inner pipeline is also replaced with a standard electrical grade insulating oil.      The transmission line and inner pipeline may be retreived from within the outer pipeline for maintenance or repair by reversing the floatation process and pulling the inner pipeline as required.  During retreival operation, the inner pipeline and transmission line are withdrawn into a storage pipeline.

Abstract: A B S T R A C T Directional valve means position machine units such as rock drill-ing machines by the aid of pressure fluid driven positioning motor means and a directional valve for controlling the pressure fluid supply thereto.  A machine unit is to be angularly positioned about a first pivot axis relative to an outlying boom frame means which in its turn is angularly adjustable about a second axis relative to supporting means.  The directional valve is included in an angle setting servo system incorporating n control unit which under movement of the boom frame means automatically governs the positioning motor 50 as to cause the machine unit to maintain its direction in the sur-rounding space in relation to a predetermined set angle value therefor.  The directional valve comprises a first element incorporating valve housing means and as a second element incorporating cooperating valve body means which are adjustable relative to said valve housing means.  These elements are syngonously (uniangularly) related one of them to the actual angle value of the machine unit and the other to the set angle value therefor.  The direc-tional valve in itself forms the control unit in that its elements have a fe?d back position defined by cooperating valve surfaces thereof.  In the feed back position the pressure fluid supply to the positioning motor is cut down or cut off when the actual angle value coincides with the set angle value. The syngonous relationship is provided by an angle transmission for trans-mitting the actual angle value or the set angle value to the directional valve to or from a fixed position in the surrounding space remote from the machine unit.

Abstract: ABSTRACT OF THE DISCLOSURE       The specification discloses a method of stabilizing aqueous alkali metal aluminate solutions against pre-cipitation of solids and/or the development of a cloudy appearance over a period of standing.  The method comprises dissolving hydrated alumina and an alkali metal hydroxide in an aqueous medium in an amount sufficient to produce an aqueous solution containing at least 30% by weight of dissolved solids.  The dissolved solids are then reacted in the presence of at least 0.02% by weight of an oligomeric or monomeric surfactant containing groups capable of bonding chemically to the aluminate thus produced.  The resulting aluminate solution is found to be stable for a period of several months at least, and thus has a long shelf life making it attractive for use in a variety of industries.

Abstract: ABSTRACT OF THE DISCLOSURE      The device for feeding filter plugs to a demand drum comprises, in combination, a gravity-feed hopper containing a supply of multiple length filter rods, said hopper being closed, in correspondence of its bottom end, by a rotating fluted drum wherein each flute of the drum is capable of housing a filter rod.  The filter rods, thus removed from the hopper, are cut into three filter plugs, which are delivered, axially aligned, onto a horizontal conveyer belt subdivided into three tracks.  As a continuation of the conveyor belt there is provided a horizontal fixed sliding surface onto which the articles slide in three rows, each leading article of the  three rows being pushed by the subsequent ones, until the leading article reaches an abutment member, where it is firmly positioned.  Also the sliding surface is subdivided into three tracks. In correspondence of the abutment member there is arranged a collecting and offsetting drum, which presents angularly spaced pick-up elements, and is subdivided into three sections (one for each track of the sliding surface), each section being angularly offset with respect to the adjacent one.  In this manner, the filter plugs are individually and sequentially collected by the collecting drum and are transferred, the one after the other, onto a demand drum.
