Abstract: CARBURETOR FOR INTERNAL COMBUSTION ENGINES                     ABSTRACT OF THE DISCLOSURE      A carburetor for internal combustion engines having a housing including a generally discoidal wall and a hub ex-tending axially from the central portion thereof, an air valve having a relatively flat radially extending surface directed toward and concentric with said discoidal wall and with a central conoidal portion having its apex directed toward the interior of said hub portion.  The housing wall and the radially extending surface of the valve define an air passage converging radially inwardly to form an annular valving construction and thence diverge into the interior of said hub.  The hub includes an annular fuel passage terminating at its upper end in a circumferential series of micro-passages for directing liquid fuel uniformly distributed into said air passage substantially at said valving constriction at right angles to the direction of air flow.  The air valve is adjustable axially toward and away from the discoidal wall of the carburetor housing to regulate the volume of air drawn into the engine with which said carburetor is associated.  Fuel is delivered under pressure to the fuel metering valve and from there through said micro-passages and controlled cams simultaneously regulate the axial adjustment of said air valve and the rate of delivery of fuel through said micro-passages according to a predetermined ratio pattern.  A third jointly controlled cam simultaneously regulates the ignition timing in accordance with various air and fuel supply settings.  The air valve, fuel supply and ignition timing settings are all independent of the existing degree of engine vacuum.

A flow restricting device is located in the through passage for restricting the flow of water through the through passage to a flow capacity of the downspout whereby than the unrestricted flow capacity of the downspout whereby the rate at which water is conveyed to the municipal sewer drainage system in storm conditions is limited to that which the sewer drainage system can accommodate from each pitched roofed structure.  The flow restricting device includes a cover proportioned to fit within the eavestrough and adapted to be mounted in a position overlying the input end of the downspout.  A drainage passage opens through the cover to permit water to pass therethrough.  The drainage passage is proportioned to permit a restricted flow of water from the eavestrough to the downspout in use thereby to achieve the required flow restriction.

Abstract: INTERLOCKING REFRACTORY FOR COVERING A PIPE             Abstract A light-weight, thermally resistant, shock-resistant refractory for covering a water pipe in a high-temperature environment.  The refractory shape is a partial cylinder in-cluding a body segment, two protuberances spaced apart from and on either side of the body segment by corresponding recesses and terminating in a void between the two protuberances.  Two identical segments, when axially aligned in juxtaposition, are fitted together around a pipe such that the body segment of each refractory shape is intimately received by the corres-ponding void of the opposite refractory shape and the pair of protuberances of one shape are closely received and interlocked with the corresponding pair of recesses in the opposing shape to form a substantially cylindrical refractory covering around the pipe.  The shape requires no additional means to support itself around the pipe.

The controls have a brake demand valve providing a brake demand pressure. retarder valve is biased by brake demand pressure from brake-off position to brake-on position for switching the retarder circuit to fill the retarder and to connect low and high speed regulator valves to regulate retarder inlet pressure respectively to increase in the low speed range and to decrease in the high speed range with increasing speed, and to limit retarder inlet pressure proportionally to brake demand.  The controls, in the low speed range, provide friction brake apply pressure proportional to brake demand, so the friction brake net apply pressure and torque decrease to zero and retarder torque increases as speed increases.  In the high speed range, retarder torque decreases with increasing speed.  Total brake power increases in an approximately straight line relation to speed.
