Abstract: S P E C I F I C A T I O N                       AN IMPROVED CONCAVE FOR AN   AXIAL FLOW TYPE COMBINE                         ABSTRACT OF THE DISCLOSURE         In an axial flow type combine, an improved concave is provided which remains open in the most adverse corn harvesting conditions, thereby increasing the overall efficiency of the machine.  The improved concave comprises a frame formed by a plurality of spaced-apart transversely extending arcuate shaped support members joined together at their respective ends by a pair of spaced-apart longitudinally extending support elements.          The frame supports a plurality of spaced apart longitudinally extending rod-like members which are generally linear throughout a substantial portion of their longitudinal extent, the linear portions of the respective rod-like members being generally parallel to the axis of a rotor positioned above the concave in the combine.  The rod-like members are provided with rotatably mounted sleeves which freely rotate about the rod-like members as crop material moves over the concave.  These rotatable sleeves facilitate the passage of threshed crop material though the openings in the concave defined between the sleeves and further serve to reduce the impact of the crop material against the concave, thereby resulting in less crop damage.

Abstract: METHOD OF MAKING A TRIM STRIP            ABSTRACT OF THE DISCLOSURE            The disclosure relates to a method of making a trim strip comprising the extrusion of a vinyl material to form a body which is so shaped that it can be confined in a peripheral slot in a roll, thereby to permit substantial pressure to be applied on the extruded body and a decorative strip by a mating roll. The top portion of the extruded body has side extensions which are supported by the edges of the recessed roll; thus, substantial pressure can be applied on the entire top of the decorative surface strip and the body to produce an adhesive bond or a bond by heat sealing. After the body is cooled, it is advanced through a number of aligned milling cutters to machine aligned recesses in the sides of the body to produce a retention cutout. After being machined to depth, the trim strip is advanced through a pair of grinding wheels to accurately form and space the recesses. During the extruding operation, a coated wire may be embedded within the body in the conventional manner.

Abstract: ABSTRACT OF THE DISCLOSURE      In this method of bleeding, hydraulic fluid is withdrawn from the master cylinder, and fluid is introduced into the system via the slave cylinder to flow to the master cylinder.          Air escapes at the master cylinder. Spent fluid can be withdrawn completely from the system but good fluid can be recirculated if the only problem is to get rid of air. Slave cylinders can be bled by connecting them in succession to a single set of conduits leading from the apparatus.  The flow along the conduits will then be controlled by operating valves manually. Alternatively the apparatus may be provided with as many sets of conduits as there are slave cylinders requiring bleeding. The apparatus is then arranged to operate automatically via each set of conduits in turn.  A novel bleed screw or bleed nipple facilitates bleeding with the present method and apparatus.  Furthermore, for preferred bleeding by this method, a slave cylinder advantageously has a bleed screw at a low level and a hydraulic pressure connection at a high level.

Abstract: Abstract of the Disclosure An adaptive equalizer and echo canceller jointly respond to a common error difference between the analog output and the quantized digital output of a data receiver in a two-wire digital data transmission system to achieve simultaneous full-bandwidth full-duplex operation.  Two-wire transmission channels are typically terminated in hybrid balancing networks which because of their fixed impedances permit "echoes" of the transmitted signal to interfere with reception of the much weaker incoming signal.  Both the equalizer and canceller are adaptively adjustable transversal structures.

Abstract: ABSTRACT OF THE DISCLOSURE           A process is provided for the removal of sulphur dioxide from a combustion gas stream containing said SO2 and particulate solids including flyash, in a wet scrubber having an aqueous slurry-containing sump zone.  The process includes the first steps of:  (a) passing the gas stream through the wet scrubber to effect SO2 removal.  The second step is (b) separ-ately and directly injecting a calcium-containing reactant into the wet scrubber to mix with the aqueous slurry in the sump zone to form, inter alia, calcium sulphite and calcium sulphate, the slurry having a pH maintained in the range of approximately 6.0 to 8.5.  The third step is (c)discharging at least a portion of the slurry from the wet scrubber.  The fourth step is (d) bleeding off a portion of the discharged slurry to maintain a controlled quantity of slurry having a solids content of ap-proximately 5 to 40% by weight, of which at least approximately 5 to 25% comprises flyash.  The fifth step is (e) recycling the flyash containing controlled quantity of slurry to the wet scrubber, and contacting the controlled quantity of slurry with the aqueous slurry to provide nucleation sites for the formation of calcium sulphite and calcium suphate crystals.  The final step is (f) co-precipitating calcium sulphite and calcium sul-phate crystals on the flyash, thereby maintaining a substantially unsaturated calcium sulphate level in the aqueous slurry, and thus minimizing scale deposition on the surfaces of the wet scrubber.  This procedure purifies combustion gases by reducing emissions of sulphur dioxide and particulate material.  The process avoids the necessity of reaction mix tanks, and elaborate wash systems.

Abstract: ABSTRACT OF THE DISCLOSURE     The invention disclosed is a liquid constant flow, drainable solar energy collector system in which a manifold feeds several evacuated glass tube solar collectors disposed on an upward side of the manifold.  The collectors are fed in parallel through an individual orifice which restricts flow rate to each solar tube.  The normal outlet of each solar tube is via an axial glass pipe which extends to its top region.  The orifices are all connected to a common header pipe in the manifold and the glass outlet pipes are all connected to a separate common header pipe in the manifold.  For each solar tube the outlet pipe is of sufficient diameter in relation to the orifice so liquid that overflows the pipe does not completely fill it and allowing an air vent passage via the same pipe.  The restricted orifices are provided by inserts removably installed between their common header pipe and the solar tubes.  The manifold is sloped to its drain and the collectors are sloped to the manifold providing full drainability; and the collectors may use pure water without danger of freeze up or need for anti-freeze mixture.
