Abstract: An electronic control circuit for actuating a solenoid-operated air-diverter valve or valves connected with the exhaust manifold of an internal combustion engine, to supply supplemental air thereto. The supplemental air reacts with some of the hot exhaust gases, producing other gases which are in general less toxic than those coming directly from the engine. The circuit responds to engine speed in such a manner that, after a predetermined period of operation has elapsed during which the speed was continuously above a predetermined value, the normally energized solenoids are shut off to thus close the diverter valves and thereby interrupt the flow of supplemental air to the exhaust manifold. This prevents overheating of the exhaust system at high engine speeds.

Abstract: A device for the recovery of fuel vapors originating in the fuel system of a vehicle, particularly at the gas tank thereof or in the carburetor float bowl. In one arrangement, a fuel vapor line connects the fuel tank to an input port of a fuel vapor storage and recovery canister containing activated carbon or charcoal, with another port thereof, referred to as a "purge" port, being connected with either the engine intake manifold or else a vacuum port of the carburetor. Carried by the canister is a self-regulating electric heater assemblage adapted to heat air flowing into the canister through a large air port, thereby to also heat the charcoal. When the vehicle is idle, fumes from the gasoline tank can enter the input port of the canister to be adsorbed and stored by the charcoal. When the vehicle is operated, vacuum from the intake manifold draws air into the canister, causing the heated charcoal to release its stored fuel which is then burned in the engine.

Abstract: Apparatus for radiation curing of decorative and protective coatings on the exterior of a can or other tubular article is constructed with a plurality of ultraviolet lamps, each of which is disposed between two runs or flights of a conveyor chain having pins that carry the articles so that each article makes two passes at each lamp to receive radiation therefrom on opposite sides of each article. Two runs of the chain are at right angles to another two runs thereof so that curing radiation impinges on the entire outer surface of the tubular article. Each lamp is disposed within an individual baffle unit including a stationary shield that surrounds a cylindrical shutter that is pivotable about its cylindrical axis between normal and standby positions. In the normal position, diametrically opposed windows of the shutter are aligned with diametrically opposed windows of the shield so that radiation from a single lamp is directed toward two flights of the conveyor chain.

Abstract: A composite clamping shell for securing the socket of an electric cigar lighter to a panel of an automobile, has a rolled sheet-metal body of tubular shape, with open ends and a clinched seam. Attached to the body is a drawn, sheet metal sleeve having a rolled screw thread. The body has inwardly displaced stop shoulders to position the sleeve, which latter has an annular out-turned flange abutting the stop shoulders. Edge portions of the body end are laid over the out-turned flange of the sleeve to hold it captive and prevent relative movement. The body is stamped out of a piece of flat sheet metal stock and thereafter rolled into the desired cylindrical shape. The sleeve is produced by drawing operations, from flat stock. Reduced manufacturing cost is thus realized.

The rear edge of the body part is engaged by the abutments on the nut part during the clamping.

Abstract: An adjustable encoder includes a source generating a first signal and transmitting it to a transducer element for generating an electrical signal responsive to the first signal. An object is rotated between the source and the transducer element so as alternately to block and to permit or unblock the path of the first signal from its source to the transducer element. The transducer element and the source are simultaneously movable parallel to the plane of rotation of the rotatable object, so that the exact timing of interruption of the first signal can be adjusted while the encoder is in operation.

Abstract: Apparatus for applying a plurality of color images to cylindrical or frustoconical articles includes a turret mounting radially extending angularly spaced shafts, each of which mounts a mandrel.

Abstract: A power door lock control for vehicles includes a manually operable member which may be the conventional lock-unlock button. One door contains an electrically powered mechanism which operates a locking bolt. Connected to the mechanism is a contact which is cooperable with a second contact on the vehicle body when the door is closed. A pulse circuit in the vehicle is actuated when the driver presses the lock button toward its "locking" position, and supplies spaced pulses to the body contact. The pulses continue at a very low duty cycle, so as to draw minimal current, until the door is closed at which time the door contact and body contact engage one another, thereby completing a circuit from the pulse generator to the powered mechanism. This in turn operates the locking bolt to secure the door. At the same time, a current sensing circuit in the vehicle detects that a pulse of current has flowed through the powered mechanism.
