Abstract: A simplified gear drive mechanism for an indicating device such as a clock. The output shaft of the indicator's drive motor carries an eccentric which orbits a multiple gear tooth orbiting gear. One gear on the orbiting gear engages a stationary ring gear having a different number of teeth while another gear on the orbiting gear engages an output ring gear having a different number of teeth. This output ring gear may, for example, be employed to drive the minute hand of a clock. To provide multiple indicators such as required in a clock, a second orbital gear train is provided having an eccentric on the output gear of the first gear train for the purpose of orbiting an orbiting gear in the second gear train. An output ring gear in the second orbiting gear train is employed to drive the hour hand of the clock. In another embodiment of the present invention, a similar orbiting gearing arrangement is employed for driving a digital indicator, such as a digital clock.

Abstract: An electric-motor-powered centrifugal fuel pump including a vacuum control device to achieve the initial priming of the centrifugal pump. The electric motor which drives a centrifugal impeller is housed within the pump itself and, as such, is immersed in the fuel being pumped. An associated filter bowl incorporates a float valve, thus becoming a filter and float bowl which controls the vacuum so that when the fuel level reaches a predetermined point, the float valve rises and engages its valve seat, thus shutting off the vacuum source. A secondary ball valve is also provided in the vacuum line so that, in the event of the vehicle's overturning, this ball valve will close the vacuum line and prevent gravitational fuel flow to the vacuum source. When the vacuum draws sufficient fuel into the centrifugal pump cavity, the centrifugal impeller is then capable of discharging this fuel under pressure through the filter to an outlet port that is connected to the carburetor.

Abstract: A large display system capable of displaying a video image receives video signals, quantizes those signals to produce a digital code capable of representing variations in the light content of the image and processes the digital code so to control individual display devices on a large matrix of such devices to have different levels of visibility to thereby reproduce the video image for viewing by a large audience. A data processor is utilized to store the digital representation of the video image in memory so that on line or off line presentations can be made.

Abstract: A timed buzzer assembly having a rectangular base with four terminals insert molded in the base and a generally cup-shaped cover member over the base providing the housing. All of the terminals project through the base member with the armature of the buzzer supported on one terminal and the coil assembly of the buzzer supported on a second terminal. For the purpose of timing the buzzer and also controlling a warning light, a bimetal timer is provided having bimetal elements one supported on a third terminal and the other supported on the above referred to second terminal. The fourth terminal is a ground to which a heating element for the bimetal timer is connected.

Abstract: An alarm device for use in a vehicle which utilizes an audio frequency oscillator to drive a buzzer or tone device audible to the occupants of the vehicle. The alarm includes a control circuit which automatically stops the alarm after a preselected interval and may include modulated or interrupted alarm.

Abstract: A warning system for detecting a burned out or defective bulb for a motor vehicle is disclosed. A transmitting circuit is connected to detect current flow through the bulb to be monitored. Failure of the bulb to draw current causes the transmitting circuit to produce a series of small voltage pulses on the battery line. These pulses are detected by a receiving circuit which causes an outage indicator light to be illuminated.

Abstract: A vehicular radiator having a core assembly consisting of a plurality of vertical rows of fluid carrying tubes separated by a plurality of rows of fins with the outer fin rows having mounting surfaces connected to side channels so that the core assembly may be suitably supported. To permit free expansion of the fluid carrying tubes and to reduce the supporting stresses for the core assembly, upper and lower header plates are provided carried by the tubes but unconnected to the side channels to permit free relative movement therebetween caused by thermal expansion and contraction. Upper and lower tanks are provided connected to the upper and lower header plates and these have suitable inlet and outlet fittings adapted to be connected to the cooling circuit of an associated engine.

Abstract: A large display system capable of displaying a color video image receives video signals, quantizes those signals to produce a digital code capable of representing variations in the light content of the image and processes the digital code so as to control individual display devices on a large matrix of such devices to have different levels of visibility to thereby reproduce the video image for viewing by a large audience. A data processor is optionally utilized to store the digital representation of the video image in memory so that on line or off line presentations can be made.

Abstract: An air core gauge is provided with a plurality of angularly oriented coils. Switching means are connected to the coils in order to control the flow of current therethrough. Pulse generators responsive to variations in frequency of electrical signals representative of a condition, such as vehicle speed or engine RPM, control the switching means so as to cause excitation of the coils to produce a resultant mmf vector, the angular position of which is related to the frequency of the signals. The resultant mmf vector causes a magnet and associated pointer to rotate to thereby provide an indication of the value of the condition.

Abstract: A bicycle speedometer tire drive gear adaptor assembly comprising a pair of helical gears engaging at an angle of substantially 120.degree.. The gears are supported in a unitary housing with one of the gears rotated by a friction wheel engaging the bicycle tire and the other, which utilizes its own teeth as a bearing, rotates at a substantially reduced speed to transmit movement through a flexible shaft to the speedometer. The angle of gear engagement aids in eliminating sharp corners or small radii in the flexible shaft. The housing is secured to the front bicycle fork by oppositely directed arcuate spring clip fingers having reverse bent ends nesting in and conforming to the shape of a pair of longitudinal grooves in the housing to securely hold the housing.

Abstract: A warning buzzer having an armature arranged to strike the wall of the cavity formed by the buzzer housing to increase the sound emitted thereby. The buzzer includes terminals molded in a base with one terminal having a coil core and magnetic return leg formed thereon with the coil bobbin received on the core having a pair of lugs on which the coil terminals are wrapped and dip soldered. The dip soldered lugs are then staked in the terminal and in a contact member for both supporting the coil and extending electrical connections thereto.

Abstract: A speedometer magnet shaft assembly having a plastic magnet shaft and integrally formed annular wall moldably secured to the magnet and flux collector. A helical gear is moulded on the annular wall for transmitting movement to the odometer. The molded magnet shaft also has a recess formed therein at each end and a peripheral recess formed therein intermediate the ends. The end recesses receive the speedometer pointer shaft and flexible shaft ends, respectively. The peripheral recess receives a portion of the speedometer frame bracket to prevent axial movement of the magnet shaft.
