Abstract: An arrangement for adjustments on carburetor control devices by which the adjustment is sealed to prevent unauthorized readjustment, leakage or accidental movement out of adjustment by the use of a heat shrinkable tube or cap shrunk into contact with both the adjustment and associated structure to prevent relative movement.

Abstract: A control system where the turbocharger of an internal combustion engine including a compressor and a turbine driven by exhaust gasses from the internal combustion engine in which exhaust gasses are bypassed to limit the speed of the turbine in proportion to the pressure of the compressor outlet above a predetermined absolute pressure which is determined by an aneroid control member.

Abstract: A vacuum motor for controlling a carburetor choke valve in which the stroke of the motor is limited to a predetermined length for a predetermined period of time after which the length of stroke is increased a predetermined amount.

Abstract: A control motor of the type used to control carburetor choke valves wherein the motor has an output member acted on by a pair of springs, one of which is effective to urge the choke valve towards its closed position when the engine is not operating and the other of which resiliently resists opening movement of the choke valve.

Abstract: A detachable quiver for bow mounting on a bow having a pair of mounting members mounted on the bow and formed integrally with a plastic quiver are maintained in connected condition by a resilient biasing arrangement formed integrally with one of the plastic mounting members.

Abstract: A fuel control system for a turbocharged engine having fuel delivered to the carburetor under the control of a vacuum operated device which is under the further control of a device sensing pressures upstream and downstream of the turbo charger compressor and delivering a vacuum signal to the fuel control device in proportion to the manifold pressure even though the latter pressure may be a positive pressure.

Abstract: A pressure regulator including a valve assembly in which a spherical valve closure element has a flat closure portion for engagement with an annular valve seat and the spherical element permits rotation and accurate alignment of the closure surface with the seat to avoid leakage.

Abstract: A carburetor choke control arrangement incorporating a temperature responsive bimetal coil and a diaphragm actuated vacuum motor supported jointly to operate on the choke valve. The length of stroke of the vacuum motor and adjustment of the bimetal coil are each achieved by a single screw adjustment.

Abstract: A two stage vacuum break or fluid motor device of the type used to control choke valves of internal combustion engine carburators. The motor uses a single diaphragm in which the fluid motor plunger operates in a first stage in response to movement of a portion of the diaphragm and in a second stage in response to movement of the entire diaphragm. The stages of movement are under the control of separate sources of manifold pressure which may be made available to the device independently of each other. The two stages of operation may be used to control one or more choke valves through a single output plunger or to control a pair of output plungers movable independently of each other.

Abstract: A fluid pressure motor having a movable diaphragm assembly and an output assembly housing a plurality of output members at least some of which can move relative to the diaphragm assembly and can be connected to separate devices for control by a single differential control pressure in the motor.

Abstract: A choke control device for delaying closing of a choke valve regulated by a temperature responsive bimetal coil after an internal combustion engine is turned off by employing a heat sink which stores the latent heat of fusion or vaporization that is delivered to the heat sink after the choke is open and the engine is operating at normal temperatures and which releases the latent heat after the engine has been turned off and cools to heat the bimetal coil and delay closing movement of the choke valve.

Abstract: A valve control mechanism for turbo-charged internal combustion engines having a plurality of valves controlling fluid flow paths to devices regulating engine operation and so arranged that when the pressure in the air fuel induction system increases from a vacuum to a positive pressure the control paths are closed to interrupt operation of the control devices.

Abstract: A time delay device for delaying movement in one direction and permitting relatively free movement in the opposite direction wherein alternate plate members and wall members in a housing are coated with a viscous grease and the plate members are rotated through a shaft connected by a one-way clutch to the control member whose motion is to be delayed.

Abstract: A control motor of the type used to control carburetor choke valves wherein the motor has an output member acted on by a pair of springs, one of which is effective to urge the choke valve towards its closed position when the engine is not operating and the other of which resiliently resists opening movement of the choke valve.

Abstract: A two stage vacuum break or fluid motor device of the type used to control choke valves of internal combustion engine carburetors.

The stages of movement are under the control of separate sources of manifold pressure which may be made available to the device independently of each other. The two stages of operation may be used to control one or more choke valves through a single output plunger or to control a pair of output plungers movable independently of each other.

Abstract: A fluid motor or vacuum break device for use with the carburetor of an internal combustion engine in which an output plunger of the motor moves in two stages in succession with a period of delay therebetween in response to variable pressure in the form of vacuum from the intake manifold of an engine. Upon admission of vacuum pressure to a variable pressure chamber a diaphragm assembly moves in a first stage after which there is a period of delay and the diaphragm assembly and plunger moves in a second stage together with a movable wall.

Abstract: A time delay valve of flexible material to be supported in an opening in a wall and having a body member provided with a recess permitting the use of a tool to position the valve in the opening in the wall from one side of the wall with the recess also accommodating displaced material during the time that the valve is being installed. The valve has an enlarged head which closes the opening and flexes away from the wall to open and permit relatively free fluid flow. A metering groove extends radially of an annular sealing surface formed on the perimeter of the head to restrict and delay fluid flow when the valve is in a closed position relative to the wall.

Abstract: A fluid motor or vacuum break for use with the carburetor of an internal combustion engine in which an output plunger of the motor moves in two stages and at different rates in each of the stages through means of an auxiliary housing supported within the main housing. Upon admission of vacuum pressure to the primary housing and output plunger moves in a first stage at the end of which vacuum pressure is admitted to the auxiliary housing causing it to collapse and move the plunger in a second stage.

Abstract: A method of forming a cup shaped housing member with an integral inlet tube extending radially to the axis of a cup shaped member from a flat strip of metallic material in progressive dies such that a tube is formed first to extend parallel to the axis of the cup shaped member and in subsequent progressive steps is moved first to a position extending at an angle to the axis and finally to a position extending radially to the axis of the cup shaped member. SUThis invention relates to a method and apparatus for forming metal parts in progressive dies and more particularly it relates to the method and apparatus of forming a dished housing member with a tube extending radially from the axis of the housing member.To provide a radially extending tube from a housing usually requires the welding of separate parts together or requires forming the assembly from molded materials such as plastic.

Abstract: A method and apparatus for making a housing member with a projecting bracket receiving adaptor from a sheet of flat material in which the material is formed in progressive dies by displacing material in the direction of die movement and also transversely thereof by a die arrangement movable into engagement with a portion of the material displaced in the direction of die movement to confine that portion while permitting displacement of the unconfined portion transversely.
