Abstract: The specification discloses an improved method and apparatus for determining the time angle of a diesel engine which, in contrast to the present day method, is one which is fast, accurate, and can be readily used on a production line basis. There is disclosed a method and apparatus which, by the utilization of pulses of fixed angular frequency produced by an encoder, and counted between the moment the pressure in the injector line of the cylinder, whose timing angle you are measuring, reaches a predetermined pressure and the moment the piston in the same cylinder reaches top dead center, a number of pulses representing the timing angle of the engine is obtained, which can easily be converted into a reading of the timing angle.

Abstract: This application discloses a method for making a candle with stones, or other desired articles, cast into the candle about the periphery thereof. This is accomplished by the use of a two step casting process, wherein a smaller core of the candle is first cast, and this core is then placed in a larger mold of substantially identical shape. The stones or other articles are then placed in the larger mold between the smaller core and the inner wall of said mold until the space therein is completely filled. Wax is then poured into the larger mold to cast these articles into the surface of the candle. Since the wax at this point will almost completely cover the articles, which are of a decorative nature and of which more of the surface should be exposed, the candle, after it has cooled, is repeatedly dipped in hot wax to remove some of the surface wax from the candle with each dipping, and then cooled by dipping the candle in water.

Abstract: This invention relates to a method and apparatus for reproducing operating conditions in induced flow devices, such as carburetors and the like, and more particularly to a system for reproducing such operating conditions which may be used in testing systems designed to test induced flow devices.In operation in such a test system, the apparatus of the present invention would cause a given air flow to flow through an induced flow device such as a carburetor, and then would cause the throttle plate of the carburetor to be rotated until the desired manifold vacuum in the carburetor is obtained, at which time the test of the carburetor could take place.

Abstract: An improved column mounted tool holder for mounting on typical basement or factory support columns of varying sizes. The tool holder includes a pair of complementay structural members that are bolted to each other about a support column to define a work surface on all sides of the column, and each structural member mounts an associated clamp member with a V-shaped clamping surface for adjusting movement to allow the clamping of different size columns. The structural members preferably are of elongated configurations with U-shaped cross sections that open sideways toward each other so as to provide upper and lower walls between which the clamp members are slidably mounted. This configuration of the structural members allows drawers to be received by the ends of the structural members to hold small parts.

Abstract: This application discloses an improved quill feed unit of the type used in automatic or semi-automatic machines for holding and advancing the tool during the machining operation, wherein the rapid advance, feed, and rapid retract movements present in each machine cycle are performed entirely mechanically.Previously, substantially all of such guill feed units have been operated by the use of a hydraulic or pneumatic power, or a combination thereof, i.e., a hydraulic or pneumatic cylinder would advance and retract the tool, while a suitable motor would rotate the tool.Despite efforts to solve them, severe problems were and are still encountered with these units. Problems such as leakage, poor start up, tool breakage and ease of tampering are commonplace.

Abstract: A method and apparatus for hot testing on a production basis, automobile engines as they come off the assembly line for performing a final check on such engines before they are installed in the automobile. The engines are tested for exhaust emissions at three points or KEY MODES of operation at which emission related engine malfunctions are most likely to appear. These points of operation are high cruise, low cruise, and idle. The engine, after it comes off the assembly line is placed in a production test stand wherein the connections for water, oil and exhaust are made, the engine is started, accelarated to the high cruise speed, and allowed to warm up for a predetermined time, after which time, measurements of hydrocarbons and carbon monoxide are taken and an appropriate indicator light lit to indicate that the engine either is within limits at this speed, or does not pass for some reason. The same procedure is followed in the low cruise and idle speeds.

Abstract: This application discloses a method and apparatus for measuring and/or adjusting the timing angle of internal combustion engines. The method of measuring the timing angle comprises the steps of running the engine and producing voltage pulsations of uniform time frequency against which are simultaneously taken measurements of two values: first, the measurements of engine speed by counting the number of pulsations for one full and precise revolution of the engine from top dead center to top dead center of one selected cylinder, and simultaneously counting the number of pulsations from the moment the spark plug of the selected cylinder fires to the top dead center (for advanced firing), or from the top dead center to the moment of firing of the spark plug (for retarded firing). Counting two of such values enables the testing personnel to express the timing angle in degrees and to have the RPM of the engine at the time of testing, neither of which would be available if only one of such two values was measured.
