Abstract: A system for automatically inspecting matter for varying composition includes one or more detection stations through which one or more streams of matter are advanced and particular materials therein are detected through their diffusely reflected IR spectra, if any, and/or through their variation of an electromagnetic field by their metallic portions, if any. A row of light sources distributed across the overall width of one or more belt conveyors may cause desired portions of the stream to reflect light diffusely onto a part-toroidal mirror extending over that overall width, whence the light is reflected, by a rotating, polygonal mirror through optical filters dedicated to differing IR wavelengths, onto detectors the data output of which is utilized in controlling solenoid valves operating air jet nozzles which separate-out the desired portions.

Abstract: A carburetor for a two stroke engine with an air passage and a separate fuel and air mixing passage in a carburetor body and the passages having an air valve and a throttle valve, respectively. A coupling connects a valve shaft of the air valve with a valve shaft of the throttle valve and has an area wherein the valves are rotatable relative to each other corresponding to a difference between an opening and closing angle of the air valve and an opening and closing angle of the throttle valve. Preferably, when the throttle valve is in an idle position, the air valve is closed and the throttle valve can be opened through at least some angle from its idle position before the air valve is moved from its closed position. Also, the air valve is preferably fully opened when the throttle valve is moved to its fully or wide open position.

Abstract: A carburetor for providing a fuel and air mixture and a scavenging air supply to a two stroke internal combustion engine has a throttle valve received in a fuel and air mixing passage and connected to a throttle drive for controlling engine operation and an air valve received in an air passage and selectively operably connected to the throttle valve by a lost motion coupling. Preferably, the throttle valve and the air valve are barrel-type valves each comprising an opening formed through a shaft extending transversely through and rotatable within an associated bore of the carburetor body.

The fuel passage includes a fuel passage bore (24), an air passage bore (19), a threaded bore (18) and an outlet passage (16) which has subsequently reduced diameters. A stepped portion between the threaded bore (18) and outlet passage (16) is tapered. The fuel jet body (25) has a middle portion forming an emulsion tube (26) and a downstream threaded portion (28) which engages the threaded bore (18). A downstream end (27) is tapered and abuts the tapered section in the bore to form a seal.

Abstract: An underground storage tank with backfill deflectors is provided to permit installation of the storage tank underground without requiring any workers to enter the excavation. The backfill deflectors are preferably elongate, and generally the same length as or longer than the storage tanks with which they are used and are installed on the bottom of the excavation on either side of the tank. The deflectors have walls which are sloped or inclined in a direction which tends to direct backfill dumped thereon underneath the storage tank. Desirably, the deflectors direct the backfill under the tank without requiring any of the workers to enter the excavation to shovel the backfill underneath the lower portion or haunches of the tank. After a sufficient level of backfill is introduced into the excavation and directed under the tank by the deflectors, the backfill is vibrated to achieve a compacted backfill under the tank which is sufficient to support the tank.

Abstract: A fuel pressure regulator is provided between the outlet of the fuel pump and an inlet of a jet pump to control the flow of fuel to the jet pump. Desirably, during low voltage conditions in a vehicle, the flow of fuel to the jet pump may be temporarily restricted or terminated to decrease the amount of fuel diverted from the engine and thereby increase the flow rate of fuel to the engine and improve the performance of the engine. The regulator may also function to bypass fuel delivered from the fuel pump in excess of the engine fuel demand to control the pressure of and limit the maximum pressure of fuel supplied to the engine.

Abstract: A protective member for an archer's fingers has a cylindrical sleeve terminating at one end in an enlarged head having an arcuately convex surface. Two of the members are arranged on an archer's bowstring so that the heads confront one another and are capable of engaging the nock end of an arrow shaft on opposite sides of the latter. The archer's fingers engage the undersurfaces of the heads, rather than the arrow shaft, thereby preventing injury to the archer's fingers.

Abstract: A carburetor for a stratified type scavenging engine has a scavenging air supply passage with an air valve therein, a fuel and air mixture passage having a throttle valve therein, a diaphragm which defines a negative pressure chamber on one side and an atmospheric chamber on its other side, and a low pressure passage that communicates a venturi portion of the fuel and air mixing passage with the negative pressure chamber. The air valve is responsive to movement of the diaphragm caused by the pressure differential across it to move the air valve between open and closed positions and a spring yieldably biases the air valve towards its closed position. The air valve is not directly mechanically connected or linked to the throttle valve. Thus, when the throttle valve is rapidly opened during engine acceleration, the air valve is not immediately rapidly opened and is not significantly opened until a sufficient pressure differential exists across the diaphragm.

Abstract: A thermosensitive wire (15), including a pair of phosphor bronze round wires which cause a short-circuit when the ambient temperature exceeds a predetermined temperature, is laid along an induction line (14), and a protective device (25) including a DC power supply unit (33) for applying a DC voltage and a meter relay (35) for detecting that the thermosensitive wire (15) has caused a short-circuit is provided on both ends of the thermosensitive wire (15). An alarm output (35A) of the meter relay (35) is outputted to a high-frequency generating circuit (24) so as to shut down a high-frequency current to be supplied to the induction line (14). With this structure, even when a metal such as a tool made of iron is erroneously set near the induction line (14), the heating thereof may be detected by using the thermosensitive wire (15) and the high-frequency current flowing through the induction line (14) may be shut down.

Abstract: A method and apparatus for dispensing multi-component foamable fluid plastic materials such as polyurethane foams. The apparatus includes a mixing chamber defined by an axial passage in a support body structure. The mixing chamber receives reactant fluids for mixing then allows the fluids to exit through an opening at one end of the axial passage. Two fluid inlet openings in a wall of the axial passage admit reactant fluid into the mixing chamber. Two mixing chamber fluid inlets formed in the support body structure communicate reactant fluid sources with the mixing chamber through the inlet openings. When retracted, a valve needle in the axial passage exposes the inlet openings to admit reactant fluids into the mixing chamber. When advanced, the needle closes off the inlet openings and pushes the mixed fluids from the mixing chamber. The valve needle includes three parallel helical grooves that help purge the mixing chamber of unreacted and reacted fluids.
