Abstract: ABSTRACT OF THE DISCLOSURE         The apparatus comprises an explosion chamber in the form of a tube closed at one end and communicating through a discharge pipe with a powdered coating batcher while a safety pipe communicates it with a mixing chamber which prepares the explosive mixture ignited in the explosion chamber by a spark plug.  Installed between the safety pipe and the explosion chamber is a circular precombustion chamber which surrounds said explosion chamber and communicates with its space through holes in its walls.  The end of the discharge pipe mounts a jet nozzle which in installed in the face of the closed end of the explosion chamber coaxially with the latter so that its outlet section is arranged ahead of the holes in the walls of the explosion chamber relative to the open end of the latter.  Due to such an arrangement, the process of discharge of the explosive mixture from the precombustion chamber through the holes in the walls of the explosion chamber into the space around the nozzle is accompanied by drawing in the powdered coating from the nozzle and its intensive mixing with the explosive mixture which pro-duces a homogeneous two-phase mixture and a more uniform coat-ing and ensures a more economical operation of the apparatus due to a more rational utilization of the coating materials.  As a result of the precombustion chamber ignition and ejector-type mixing of an explosive mixture with a powder material to be applied, the apparatus guarantees that the process parameters are maintained with a high degree of stability, allowing high-quality coatings having constant physical, mechanical and op-erational properties to be produced.

Abstract: Inventor:  Samuel C. Scott and David R  Wells Title   :  STRIPPABLE FORM FOR CONCRETE BEAMS AND BEAM-DECK            CONSTRUCTION     Abstract of the Disclosure A lightweight, very strong from for a concrete beam in-cludes a plurality of U-shaped brace members having vertical, light-weight steel deck sheets secured to the uprights thereof, a strippable, non-stick, plastic liner for contacting the concrete of the beam and a rigid foamed plastic filling the space between the liner and the steel sheets, so that is supports the weight of the concrete poured onto the strippable, plastic liner.  A column form is arranged to mate with the beam form, and the beam form may be used to mate with flying deck forms producing an integral, combined column, beam and deck structure.  The forms are arranged for easily joining short beam sections to make long beam forms, and to join columns and floor decks with a smooth joint requiring no finishing.  The strength of the beam forms reduces the quan-tity of supports necessary to hold the weight of the forms and poured concrete, and their configuration provides easy and quick stripping of the forms from the set concrete.

Abstract: ABSTRACT OF THE DISCLOSURE         An enduring cage for fish or other aquatic animals is provided.  The structure of the cage is such that it can be made of deterioration-resistant materials at a reasonable cost.  The cage has a top frame made of bent aluminum tubing or pipe.  The tubing is slit so that it has a horizontal gap or slot into which are inserted the upper edges of flexible netting side walls.  The top frame is strengthened by the use of: an aluminum top sheet inserted into the same slot as the upper edges of the netting and forming a partial  cover for the top of the cage.  The tubing then is clamped, by means of bolts inserted through holes in the tubing, and the edges of the netting and the top sheet.  The netting and top sheet are held tightly and evenly in place.  The side walls and bottom of the cage are made of netting panels which are fastened together at their edges to form seams.  The seams are formed by slitting conventional polyethylene tubing, inserting the edges of two side walls into the tubing, and stapling through the tubing.  The cage preferably has flotation material to support the cage on a body of water with the top above water. The cage also preferably has a hinged aluminum lid with a hole through which feed can be deposited into the cage.

Abstract: FLOW COMPENSATING EMERGENCY  HYDRAULIC  SYSTEM           ABSTRACT OF THE DISCLOSURE      An Emergency or back-up Hydraulic System for use with a primary hydraulic system in motor operated equipment is dis-closed.  The system illustrated is a steering system for a vehicle and includes a motor driven pump and wheel driven pump for supplying hydraulic fluid to the steering system of the vehicle.  The motor driven pump and the wheel driven pump are connected in series so that the fluid discharged from the motor driven pump is supplied to the inlet of the wheel driven pump.          The inlet of the wheel driven pump also communicates with the reservoir as for example through the anticavitation check for the engine driven pump.  By-pass connections are provided around the wheel driven pump so that fluid in excess of the demands of that pump are channelled to the steering circuit when the engine driven pump is in operation.  The system disclosed pro-vides that the demands of the wheel driven pump are met by the engine driven pump and/or the reservoir depending upon the relative speeds and capacities of the engine and the wheel driven pumps.  The system disclosed is flow limiting so that the steering or other hydraulic system is not overwhelmed when both pumps are in operation.

Abstract: ABSTRACT OF THE DISCLOSURE          A method and apparatus far sequentially feeding elongated bodies, such as beams, timber, planks, or the like, one after the other from an uninterrupted layer of the bodies, wherein they are arranged in a row extending transversely of the row and directly engaging each other, to a conveyer.  The layer of bodies are supported in such a way that the row of bodies is urged forwardly with an end body situated at the leading end of the row and engaged by the next body which in turn is engaged by the third body and so on.  A stop structure engages the end body for temporarily holding the row against forward movement, and a moving structure is operatively connected with the stop structure for temporarily displacing the stop structure away from the end body at the leading end of the row to release the end body for movement away from the next body so as to create at least a small clearance between the end body and the next body.  While this clearance exists a lifting structure engages the end body and lifts it away from the layer and deposits it on the conveyer.          The moving structure then returns the stop structure back to its initial position for engaging the next body when it occupies the position previously occupied by the end body.  These operations are repeated with respect to the next body, and so on.  The apparatus is useful for feeding timber beams into a sorting machine.

Abstract: Patent Application Papers of Fred K. Broyan For:  Gas Compressor Valve Case 116 Abstract of the Disclosure The invention essentially comprises a compressor valve wherein the area of the tapered port in the inlet seat is larger than the area of the exhaust ports in the plate and guard.  In addition, the exhaust ports are formed in the plate and guard around the respective inlet ports in the form of a staggered annulus.  The larger open area in the seat enables the plate to be opened with lower pressure and the staggered annulus configuration produces substantially more open area through the valve for reduced plate lift and improved breathing.     There is also disclosed a second embodiment of the invention which utilizes tabs for aligning and guiding a movable and flexible disc between the seat and guard with-out the use of alignment pins and valve springs.

Abstract: Abstract of the Disclosure The invention relates to solutions which are stable on storage and which contain curable mixtures of polymaleimides, comonomers for these polymaleimides and, optionally, polymeri-sation catalysts and compounds which contain at least one furyl radical, preferably furfuryl alcohol.     The solu-tions are used for the manufacture of crosslinked polymers containing imide groups.     Usually a substrate is impreg-nated with the solution.    After drying, curing is carried out at 100 to 300°C.    Using a known method, for example, glass fibre fabric is subjected to hot pressing together with a copper foil, curing being effected.    This gives corres-pondingly copper-coated laminated sheets which are outstand-ingly suitable for the manufacture of printed circuits.
