Abstract: An assembly for retracting missile launch lugs out of the airstream, to reduce aerodynamic drag, after the missile has been launched from an aircraft. The assembly, which is integrated with the missile, includes: an aerodynamically configurated housing; a lug fitting that is positioned within the housing and is movable through an opening in the housing; and a spring, within the housing and attached to the lug fitting and to the housing, for biasing the lug fitting to remain within, or to return into, the housing. Unlike the prior art, the assembly: permits the automatic retraction of the exposed launch lugs after missile launch; does not result in the ejection of any element or component during or after launch, and therefore precludes potential damage to the missile or to the aircraft; and, is adaptable for use in combination with a left-hand or a right-hand missile.

Abstract: Hydraulically powered percussive apparatus for breaking rock, drilling etc. in which a combined spool valve and hammer reciprocates in the bore of a cylinder structure. A high pressure fluid inlet leads to the bore and a low pressure outlet leads from the bore. A fluid flow passage communicates with the bore at two axially spaced locations. As the hammer reciprocates, it cyclically connects, via the bore, the inlet to the passage and the outlet to the passage. Pressures in the inlet and outlet fluctuate between fairly narrow limits whereas the pressure in the passage fluctuates between a pressure approximating inlet pressure and a pressure approximating outlet pressure. The hammer has two operating faces. The first of these is exposed to the relatively steady inlet pressure and the second is subjected to the widely varying pressure in the passage.

Abstract: Better coffee is made in a conventional percolator when the percolator is heated on a metal heating plate having a planar top surface and a locating recess centered in the surface. A small metal spacer having two oppositely directed, substantially planer and parallel faces is provided with a fixed locating projection on one of its faces. The dimensions of the projection permit it to be slidably received in the locating recess of the plate so that the bottom face of the spacer makes heat-transmitting area contact with the surface of the plate. When a water-filled percolator is placed on the top surface of the heating plate in the absence of the spacer, the water may be quickly heated almost to a boil. When the spacer then is inserted and the percolator centered on the top face of the spacer, direct heating of the water in the percolator is limited to water in the pumping assembly of the percolator during coffee brewing.

Abstract: An electronic control for controlling the degree of toasting of a bread slice in a toaster. The control includes a thermocouple located within the passage of the toaster for the bread slice and responsive to the temperature of the toaster casing, the slice of bread and the air temperature within the passage to produce a voltage proportional to the resultant temperature. This voltage is integrated and actuates an electronic pulse generator with an adjustable pulse width which produces a triggering pulse. This pulse is used to actuate a solenoid which unlatches the support for the bread slice. The operational amplifier has a predetermined output voltage of reference defining the threshold of operation of the pulse generator. The electronic control is very stable and, therefore, produces uniform toasting, since it integrates the time required to obtain the desired degree of toasting as a function of the temperature variation to which the bread slice is subjected.

Abstract: A split four-cycle engine in which the cylinders are arranged in pairs. The intake and compression strokes take place in one cylinder. The power and exhaust strokes take place in the other cylinder. The cylinders are connected by a passageway which is controlled by valves. The valves permit gases which are compressed in one cylinder to be transferred to the second cylinder where they can be burned to produce power. The pistons in the two cylinders are connected to separate cranks. These cranks are connected by a set of differential gears in a manner which will cause any change in the angular position of the rotor of the gears to change the phase relation between the cranks. This will be converted into a change in the compression ratio of the engine in a manner which will be described in detail later.

Abstract: A pneumatic pressure control system which controls the ratio of fuel to air in the intake manifold of the engine includes a valve assembly which is operative in response to the combined action of the negative pressure existing in the intake manifold and positive pressure from an air pump operated by the engine. When the sum of the negative and positive pressures acting on opposite sides of a diaphragm are sufficient to overcome a spring force on the negative pressure side of the diaphragm the movement of the diaphragm will cause the operation of the valve to admit atmospheric air pressure either directly into the intake manifold or to a fuel regulating device to operate a further valve to reduce the supply of fuel to the carburetor.

Abstract: An EGR control valve is closably disposed in an EGR passageway connecting an intake passageway and an exhaust gas passageway which leads to an internal combustion engine. The EGR control valve is operated to control recirculated exhaust gas flow by varying the exhaust gas pressure in a chamber between a restriction disposed in the EGR passageway and the EGR valve, in accordance with variations in a venturi vacuum in the intake passageway to prevent the recirculated exhaust gas flow from being affected by the exhaust gas pressure in the EGR passageway upstream of the chamber. Furthermore, the EGR control valve is arranged to be controlled so that the amount of the recirculated exhaust gas flow is reduced during high engine speed and low load engine operation.
