  • Patent number: 4242313
    Abstract: Processes for the production of alumina and cement constituents from fly ash, in which the fly ash is subjected to magnetic separation removing magnetic constituents; the remaining non-magnetic fraction of fly ash is then mixed with a calcining agent and water, pelletized, dried and calcined, cooled, and then either acid cured or subjected to a hydrothermic shock treatment in sulfuric acid; the mixture is then diluted with water, filtrated, purified by a solvent extraction process, and evaporated yielding aluminum sulfate, which is then subjected to liquid-solid separation and decomposed at an increased temperature at which the sulfur in the form of sulfur oxide gases and the water vapor is driven off, alumina remains. The leach residue of the alumina extraction yields useful material for cement production.

  • Patent number: 4217809
    Abstract: In a system which sizes and lubricates lead bullets, an indexing plate, being chain driven, and having an indexing post, is mounted horizontally and in such a manner that the indexing post engages indexing detents in a transfer plate, having a plurality of bullet receiving holes. The transfer plate also mounted horizontally, and which has circular scallops whose radii and centers of curvature are coincident with the contacting surface of the indexing plate, providing an indexing to the transfer plate and a positive lock in between index positions; and a lubricating mechanism using a harmonic motion thus providing a lubricating piston with a long time in which to exert nearly maximum pressure on the lubricant and thereby optimizing the lubricating stroke; all being properly timed with the proper movement of the punch; so as to provide simultaneous and high speed sizing and lubricating of bullets.

  • Patent number: 4205683
    Abstract: An adapter for use with a coaxial activating syringe balloon catheter assembly is provided with a simplified slide valve which permits a precise amount of fluid to be introduced into the balloon and held therein. The fluid is injected by means of a metering syringe which can thereafter be removed without deflating the balloon. A simple longitudinal movement of the adapter will release the fluid pressure in the balloon for deflation when desired.

  • Patent number: 4159490
    Abstract: This invention discloses a system whereby a recorded magnetic tape is played on a tape recorder presenting information in audio format to the driver and passengers of vehicles. The tape recorder may be automatically controlled so that particular descriptive, informative, or instructional passages are played at appropriate locations along a determined route. The recording is correlated to distance traveled by a device which senses the operation of the cable which drives the vehicle odometer, and by corrective information regarding tire diameter and cable to wheel rotation ratio. The correlation is correctable to correspond to an external reference system, specifically mileage markers along interstate or other highways which have standard mileage markers, thus insuring a high degree of continuous synchronization between the location of the vehicle and the particular passage played.

  • Patent number: 4151849
    Abstract: In a tobacco pipe, a tobacco storage chamber is integrally formed as a part of what otherwise would be the pipe stem, and the bowl is rotatably attached to the tobacco chamber so that to refill the empty bowl, the bowl is rotated from its normal position to a position where it faces the tobacco chamber; the bowl is refilled by tapping the chamber or the entire pipe, and then being rotated back to its normal position. Attachment of the bowl to the tobacco chambers is accomplished by means of a bail wire passing through eyelits on the tobacco chamber and hooking over ears on the bowl.

  • Patent number: 4138099
    Abstract: A materials handling device for handling sheets of plywood, sheet rock, plate glass or other flat materials. The device has a padded channel base, which supports the material, over a substantial length, thus eliminating problem of dents, and breakage in the material. At approximately the mid-point of the length of the channel base is affixed a padded broad clamp, which secures the material in the base channel. The securing of the material in the device, along the length of the base channel utilizes the inherent rigidity of the material to add to the rigidity of the device. The broad clamp is affixed to the base channel in such a manner that the broad clamp is high enough above the base channel to provide superior stability, minimizing tipping. At one end of the base channel is affixed a cross member, supporting floor engaging wheels, of sufficient width to insure stability. At the other end of the base channel is affixed, a handle to facilitate moving from one location to another.

  • Patent number: 4110988
    Abstract: A method for forming domes from subterranian diapiric material, especially salt to facilitate the genesis and extraction of oil therefrom, and therearound, characterized by the following process. First, a series of continuous wellbores having vertical first section in the area in which is desired to create the dome, penetrating the overburden layer to near the layer of diapiric material is drilled and a second section thereof contained in the salt formation and a third section thereof rising vertically from the distal end of the second section to the ground surface, is formed. Each of the wellbores is arranged with respect to the others so that the second sections emanate from the desired dome area in a radial-like pattern. Next, a steel well casing sealed at all joints and connections when complete, is inserted into each of the wellbores extending the entire length thereof.
