  • Patent number: 3944381
    Abstract: Valve means for use in a reciprocating compressor having cylinder means with a piston operable therein. The valve means include an inlet body and a discharge valve assembly, with the inlet body having a base incorporating an inner wall member and an outer wall member extending therefrom in spaced, concentric relationship. The wall members have a plurality of spaced recesses therein and a top is secured to the wall members remote from the base so as to define a passageway having a plurality of openings in both the inner wall member and the outer wall member. The volume of internal flow passages is relatively large and thus there is reduced pressure drop of gas passing through the inlet body. The base and the top are bonded to one another by brazing to form the inlet body. The construction is simple, is readily fabricated by mass production techniques, and is relatively inexpensive.

  • Patent number: 3940977
    Abstract: The disclosure describes apparatus for disabling selected cylinders of an internal combustion engine operated by periodic cycles of ignition signals. The apparatus prevents one or more predetermined ignition signals in each cycle from energizing engine components, such as spark plugs, which normally receive the ignition signals. In order to achieve this purpose, a clock pulse generator generates a uniform pulse in response to the receipt of each ignition signal from the engine. Three bistable flipflop circuits are used to produce output signals having states representative of the number of clock pulses received from the clock pulse generator. Gating circuitry returns the output signals to an initial state after receipt of a predetermined number of clock pulses, such as the number of cylinders in the engine being diagnosed. As the apparatus commences operation, removable setting means set the output signals to their initial state by means of a setting pulse generated by one of the ignition signals.

  • Patent number: 3939624
    Abstract: A process and apparatus for packaging articles, particularly fresh meat pieces, in a substantially gas impermeable flexible container. In the packaging of fresh meat, the process enables the meat to be held for extended periods of time, and yet the natural color of fresh meat is maintained and the bacteria growth does not exceed limits which would cause the meat to be considered inedible. The fresh meat is first placed in an open, substantially gas impermeable flexible container. Hollow passage defining means are inserted through the open portion of the flexible container, and while the top is being temporarily sealed, the container is vacuumized for removing substantially all the air and oxygen therefrom. After the air is removed, carbon dioxide is added to the container, the concentration of the carbon dioxide being such as to avoid significant bacterial growth on or in the meat over extended periods of time, while avoiding discoloration of the meat.

  • Patent number: 3935825
    Abstract: An improved apparatus for withdrawing agglomerated solids from a fluidizing chamber housing a main, fluidized bed of finely divided solids which comprises at least one withdrawal chamber having a width less than the fluidizing chamber and positioned below the fluidized bed. This withdrawal chamber has sufficient dimensions (width (or diameter when cylindrical) and depth) to contain a second fluidized or semi-fixed bed within said chamber when a high velocity gas stream is introduced into the bottom portion of the withdrawal chamber. This high velocity gas stream forms an inverted cone in the withdrawal chamber, wherein the walls of the cone are defined by the fluidized or semi-fixed bed within the withdrawal chamber. The velocity of the gas stream is adjusted to selectively remove high density agglomerates downward from the main fluidized bed without removing the fluidized solids in admixture therewith.
