Abstract: ABSTRACT OF THE DISCLOSURE        A safety circuit for a marine signal device adapted to be fired after being dropped into sea water.  The device has a casing which will allow the water to enter when ready for firing. A salt water battery, a water pressure operated switch and an electric blasting cap are all connected in series within the casing.  A resistor of selected value is connected across the terminals of the battery so that the battery will be discharged in a predetermined time if the blasting cap fails to be detonated by the action of water pressure on the switch at a predetermined depth.  Furthermore, a shunt is provided between the leads of the blasting cap to reduce the hazards during handling due to static charges or radio frequencies.  The shunt may be manually removed prior to firing or in one embodiment the pressure operated switch automatically disconnects the shunt when the switch is operated by water pressure.

Abstract: ABSTRACT OF THE DISCLOSURE           A fuel injection control apparatus of the kind in which an auxiliary throttle air flow monitor responds to flow of air through an air passage, and by that response influences switching means for the injectors such that the injector on-time is determined by the flow monitor.  It is a feature of the apparatus that a control element is arranged to intrude into the air passage to form a restriction to flow of air and thereby influence the flow monitor position, and to also provide a stop which is engageable by the flow monitor to determine a minimum flow position of that monitor. The control element position is regulated by a device which responds to changes in engine temperature so that the control element intrusion is at a maximum under cold conditions and is at a minimum or is non-existent at normal operating temperature of the engine.

Abstract: ABSTRACT OF THE DISCLOSURE A semiconductor image sensor as a sensing structure divided into vertical columns and horizontal rows of elemental sections.  Each element includes a photo-sensor and a portion to receive charge overflow.  The photo-sensors and portions to receive overflow are covered by a transparent electrode. Each elemental section in each vertical column is connected to a vertical shift register by a separate charge transfer section covered by a shift electrode structure to which two-phase clock pulses are applied.  One end of all of the verti-cal shift registers is connected to a three-phase horizontal shift register.  When the potential of a given photo-sensor is higher than that of the transfer section connected to it, light-generated carriers in the photo-sensor are transferred to the vertical shift register to which that transfer section is connected.

Abstract: Abstract of the Disclosure Hydrogen sulfide is removed from a gas stream in an oxidation-reduction system by contacting the gas stream with an aqueous alkaline chelated iron solution in which the iron is in the ferric state to absorb hydrogen sulfide and convert it to elemental sulfur which is recovered. The solution is regenerated by aeration. The chelated iron solu-tion contains two different types of chelating agents, on of which is selected to bind ferrous ions so as to prevent precipitation of ferrous sulfide, and the other of which is selected to bind ferric ions so as to prevent precipitation of ferric hydroxide. The absorption step of the process may be operated under either aerobic or anaerobic conditions.

Abstract: Abstract of the Disclosure A non-silver halide photothermographic element comprises a conbination of certain energy sensitive organic dyes capable of forming or destroying an active species upon selective exposure to actinic radiation to give a positive or negative image after heat development of the element.  The element also comprises an oxidation-reduction image-forming composition comprising a silver salt oxidizing agent and a non-radiation sensitive  organic reducing agent.  A method of developing a latent image in the photothermographic element to a negative image comprises overall heating the element. Alternatively a positive image can be produced in the photo-thermographic element by imagewise exposure of the element to ultr violet light and subsequent overall exposure to tungsten light followed by overall heating.  None of the prior non-silver halide photothermographic materials provided such a capability.

Abstract: ABSTRACT OF THE DISCLOSURE         Each car on a freight train is equipped with what is called a brake control valve.  This valve is in the automatic air brake system and causes the air brake on the individual car to be applied when the pressure in the main brake pipe which runs throughout the train is reduced by the engineer or by any other cause.  Sometimes, the brake control valve will malfunction, thereby causing it to go into the emergency brake position, either during normal service braking or at other times.  When it goes into the emergency position, the brake pipe opens to the atmosphere and the resulting sudden reduction in pressure at that point causes all of the brake control valves on the train to go into emergency position causing a full emergency brake application throughout the train.  With long trains, quickly finding the malfunctioning brake control valve is quite a chore. This invention provides a method and means of almost immediately indicating the location of a defective brake control valve by timing a pressure wave front propagated by the malfunctioning valve to the front and rear ends of the train in response to separate transducers which transmit radio frequency (RF) signals to a receiver and separate counters which count clock pulses from the time of receipt of respective RF signals to determine difference in the time for the pressure wave to reach the ends of the train to determine the location of malfunction from one end or the center of the train, depend-ing upon the clock pulse rate used.
