Abstract: A land irrigation system in which a continuously traveling sprinkler line is supplied with water from spaced risers mounted on a stationary water supply conduit extending in the direction of the movement of the sprinkler line to continuously supply water to the sprinkler conveyance, carrying a rotating water manifold with three rigid water carrying arms extending from the manifold at 120.degree. to each other for successive connection to water outlet valves on the risers, moves along the water supply conduit. The outlet from the manifold is connected to the inlet of the sprinkler line through a conduit having a swivel joint whereby the manifold and rigid arms can rotate through 360.degree. relative to the inlet of the sprinkler line. The inlet end of each rigid arm has a coupling device for coupling with outlet valve of a riser and for opening and closing the riser outlet valve. One rigid arm is fluidly coupled to the supply line at all times.

Abstract: A lightweight apparatus for lowering a load at a controlled rate utilizes an elongated load-carrying strand and a slider assembly mounted on the strand to support a load for controlled downward sliding movement along the strand. The slider assembly includes a brake which is manually operable to control movement of the slider from a complete stop to substantially free fall conditions. In a preferred embodiment, the brake is spring-loaded to an intermediate position to permit a load to be lowered at a safe, relatively slow rate without actuation of the brake. When such preferred embodiment is used by a person to lower himself, a brake control lever may be manually displaced from the intermediate position to increase or decrease the rate of descent.

Abstract: An improved sheet steel suitable for the production of containers and the like has a thin composite coating of nickel and zinc plated on both sides thereof. The steel substrate may be flat rolled blackplate and the composite nickel-zinc coating may be plated thereon by drawing a running length or strip of the steel through a nickel electroplating bath to which has been added the necessary concentration of zinc, and electrodepositing the two coating metals simultaneously and in the desired proportions. The coated steel sheet is particularly useful in forming drawn and ironed cans although it may be used for other purposes.

Abstract: A plurality of sole flue-heated, non-recovery coke ovens constructed in side-by-side relation in a battery have their chimney uptake outlets connected to a common combustion tunnel extending longitudinally of and above the battery and connected to stacks at spaced intervals along its length. Each oven has a bypass flue directly connecting the top of its coking chamber to the combustion tunnel, and a normally closed valve in each bypass is operable to selectively connect the coking chamber to the tunnel to permit charging gases to be drawn from the chambers to be burned in the tunnel and stack. The bypass valve is closed during coking so that the partially burned gases from the crown of the coking chambers are led through downcomers in the oven walls to the sole flues where a controlled amount of combustion air can be admitted to promote the continued burning process and provide maximum heat in the sole flues.

Abstract: An alarm system, particularly for use on a train, responsive to a plurality of different alarm conditions for providing outputs for indicating which one or ones of the alarm conditions have been detected. A signal having at least as many frequency components as there are alarm conditions is generated on a transmission line which runs the length of the area over which the conditions are to be detected. Alarm sensing switches are connected to taps of the transmission line, and each switch is connected to a frequency dependent impedance means which is resonant and has a low impedance at one of the frequencies. A filter is provided for each alarm condition to be detected, each such filter having a band pass at one of said resonant frequencies. The presence of an alarm condition causes an alarm switch to change state, which causes one of the impedance means to short circuit a frequency which otherwise would have been passed by one of the filters, thus indicating the presence of an alarm condition.

Abstract: A system and method for providing entertainment and/or information to vehicles travelling along a roadway. The system of the invention enables the driver to tune his car radio to a single station while travelling on a specific long-distance road, and to receive high quality and continuous radio reception for the duration of his trip on the road. An antenna comprised of at least one conductor is strung adjacent to the roadway and parallel thereto, and is excited with an amplitude modulated radio frequency signal within 550 to 1650 khz broadcast band so that each vertical slice through the antenna is effective as an electrical multipole. The antenna excitation signal is arranged to be large enough so that the vehicles on the roadway, which are substantially within the near field of the antenna, receive substantial and usable radio signals, but small enough so that radiation at distances beyond the roadway is negligible, so as not to interfere with broadcast reception beyond the highway.
