Abstract: An urban transportation system which comprises a pool of rental urban vehicles all having the same size and physical configuration and having a range of driving which is limited as compared to the range of vehicles that are powered by internal combustion engines. The system includes a computer-controlled mechanized facility for delivering, receiving, processing, servicing and storing the vehicles. Vehicles are automatically recharged while in storage. The system includes areas for on-street parking of the vehicles. There are also several features to combat theft of the vehicles. A user may obtain the most readily available vehicle from any place in the system and return the vehicle to any other place within the system.

Abstract: An apparatus for destroying mosquitoes by luring them into the apparatus where they are killed and their remains are incinerated. In order to lure the mosquitoes to the apparatus a mixture is emitted that attracts mosquitoes. The mixture contains a chemical attractant for mosquitoes that is stored in a container and metered out automatically. The mixture also contains carbon dioxide that is produced by the incineration of the mosquitoes and the chemical attractant. The apparatus includes an electric heater that heats the apparatus so that its skin temperature approximates the temperature of human skin. Once the mosquitoes are within the apparatus, a high velocity stream of recirculated air captures and carries them to a fan where they are killed and shredded. The shredded remains are incinerated to produce the carbon dioxide and to avoid the disposal of captured mosquitoes. Only a small portion of the recirculated air is emitted to the atmosphere thereby minimizing the consumption of electrical energy.

Abstract: A pollution control system for capturing and incinerating the emissions to the atmosphere which arise when incandescent coke is pushed from a coke oven, includes a hood for capturing the emissions and a stack mounted on top of the hood for incinerating the emissions and in which a natural draft is produced for pulling the emissions into the hood. The hood is mounted on a railroad car which may be self-propelled or towed by a locomotive. The stack has a combustion system for producing heat therein, a damper for regulating the draft and a venturi section for mixing the particulates with the gasses. The mounting of the hood incorporates a power-operator for moving the hood into or away from contact with the coke guide of the coke ovens.

Abstract: A process and apparatus for absorbing heat from the cooling of metal slabs and other metal products following rolling, casting, or other heating to shape the metal products, and the converting of the heat to a useful form of energy. During the process of cooling the metal products, heat from the metal is transferred to an absorbing medium by means of radiant and convective or conductive heat transfer. The absorbing medium may be water which is converted to steam. The apparatus includes necessary piping, circulating fan, steam drum, pumps and heat insulation.

Abstract: A waste liquor treatment system comprising an evaporator in combination with a gas cooler, the evaporator providing fractional distillation of waste liquor, thereby separating the liquor into its several components of gaseous vapors, purified water and concentrated brine. Condensed liquor from the gas cooler or flushing liquor used to spray an industrial process gas in the collecting mains of the gas-producing plant provides thermal energy from its waste heat to run the evaporator. The evaporator consists of a boiler section, a condenser section, a vacuum pump, a liquor circulating pump, and nozzles for extracting the products. The gas cooler may be one or two stage. In the one stage cooler, the hot liquor which condenses in the gas cooling process or flushing liquor from the collecting mains of the gas-producing plant provides energy for the evaporator through means of a heat exchanger.

In the two stage gas cooler, the hot liquor in the first stage is circulated directly to the boiler section of the evaporator. The hot liquor from the second stage is circulated through a separate heat exchanger.

Abstract: A machinery locating device comprising power-activated clamps which are restrained within a housing and which engage with one or more adjustably positioned stops. The clamps are secured to a moving piece of machinery such as a crane and the stops are secured to a fixed structure. When the clamps are open, the machinery can move freely past the stops. When the clamps are closed on the stops, the machinery is accurately positioned with respect to the structure. Interlocking is provided to insure that the machinery drive is disconnected before the clamps may be applied to the stops, and to insure that the clamps are opened before the machinery drive may be engaged.The locating device is especially suited to the accurate, repetitive positioning of massive moving machines such as travelling cranes, charging machines for the coke ovens and so forth.

Abstract: A coke quenching steam generator comprising a vertical, refractory-lined pressure vessel for quenching of incandescent coke and producing useful steam from the sensible heat in the coke. Included in the pressure vessel are pressure-tight doors for receiving and discharging the coke, water sprays for quenching the coke, a hopper for receiving the coke and a gate and feeder for controlling the discharge of the quenched coke. External to the pressure vessel are a crane for lifting containers of incandescent coke to the receiving hopper of the pressure vessel, valves for controlling the flow of steam and water, a high efficiency cyclone for cleaning the steam, a belt conveyor for receiving the quenched coke, pumps, water storage tank, piping and controls.

Abstract: A gun for repairing the refractory walls of a coke oven comprising an air-cooled, pressurized, insulated tube which contains an internal pipe for conveying refractory repair material. The tube is mounted in a support at one end, so arranged that the tube can be rotated about its axis and tilted. The other end of the tube has a nozzle for spraying the refractory repair material at right angles to the axis of the tube. The operator is stationed at the support end and can observe the deposition of repair material by looking through a telescope at the support end which is directed to an angled mirror and open sight port at the other end. Air is blown through the tube to keep it cool and out of the sight port at high velocity in order to prevent the refractory repair material from entering the port and coating the mirror.

Abstract: A process for absorbing the heat from the cooling and solidification of metallurgical slags and converting of said heat into a useful form of energy such as steam. The molten slag is poured against a moving heat-transfer surface and is cooled by contact with said surface. Energy is released to said heat-transfer surface during the cooling process and is, in turn, transmitted to water which is converted to steam. Included with the process are necessary piping, steam drum, pumps and heat insulation.
