Abstract:
A high asphalt content paving material containing diatomite. The diatomite stabilizes the additional asphalt preventing bleeding, rutting and shoving. The diatomite must be present in sufficient quantity to adsorb at least the excess asphalt and, preferably, all of the asphalt present in the mix. A method of calculating this optimum diatomite content is presented. Further, a method of adding the diatomite to the mix in order to minimize damage to the diatoms is disclosed.
Abstract:
A composition for forming a high temperature, alkali resistant refractory fiber. The compositional formulation, by weight, is 45-76% silica, 12-32% alumina, 5-30% zirconia with a silica to alumina ratio in the range from 1.8 to 4.0. These fibers are chemically resistant in both acidic and alkaline environments even when heat treated to temperatures exceeding 500o (260oC) in such environments. The fibers are suitable for reinforcing calcium silicate cementitious products, which products are also claimed. Another compositional formulation, by weight, is 46-52% silica, 32-38% alumina, 13-18% zirconia with a silica to zirconia ratio in the range from 2.6 to 3.8. These fibers have a maximum service temperature in the range of 2550oF (1400oC) to 2650oF (1455oC) and exhibit better shrinkage resistance than similarly rated commercially available refractory fiber.
Abstract:
An improved luminar having an adjustable lamp socket. The adjustable socket comprises a generally cylindrical shaped socket shield (48) which is fixed to the ballast housing (14) of the luminar and is positioned around the lamp socket (20) with the socket shield having formed therein a bracket channel and a guide channel. A generally U-shaped bracket is fixedly attached to the socket (20) and has identification means formed thereon designating the relative position of the socket within the socket shield. The bracket also has formed thereon at least one protuberance for positioning in the guide channel means formed on the socket shield. The generally U-shaped bracket is positioned within the bracket channel means and is designed for movement within the channel in the desired position of the lamp in the reflector of the luminar. Locking means are provided for locking the U-shaped bracket within the socket shield at the desired pre-determined position.
Abstract:
A wrap-around style beverage package and production blank having new and improved locking features. The novel locking features comprise primary adjustable locking means (56, 58, 60, 62), secondary punch-style locking means (64, 66) and tertiary locking means (68, 70, 96, 98) located on the overlapping margins of the package.
Abstract:
A carton (10) for packaging a plurality of articles (56) having rectangular or square bases and sides such as aseptic packages and the carton blank therefor. In one embodiment the carton includes a base (14), side panels (16, 18), inner and outer top panels (20, 22) with handle straps (40, 42) and partial end panels (24, 26) held in an upright position by tuck flaps (60, 62, 64, 66, 78, 80, 82, 84). In other embodiment the carton includes a base (98), side panels flaps (100, 102), inner and outer top panels (104, 106), partial end panels (108, 110) and tear strips (120, 122) on the side panels to convert the carton to a display.
Abstract:
The luminaire (10) is capable of being ceiling mounted and has a through-way electrical connection formed in a fixed housing (12) which is mounted on the ceiling or suspended from the ceiling by an attached pipe (34). The top fixed housing (12) contains a finger-safe female terminal block and a through-way means allowing building wire to be pulled straight through the housing. A pivotable housing (14) is pivotably connected to the fixed housing (12) and contains a mating male terminal block (42) which is positioned within the housing. The fixed housing and the pivotable housing may be locked together by means of a locking latch (44) so that upon release of the latch, the intermediate pivotable housing is capable of pivoting away from the fixed housing to electrically disconnect the fixture from the electrical circuit. The new and novel luminaire may be fused as desired adjacent to one or two of the male terminal connections.
Abstract:
Un procédé et un appareil permettent de récupérer les fibres inorganiques de bandes continues de rebut en fibres inorganiques. Un liant, tel qu'un liant organique, doit être enlevé avant que les fibres puissent être ré-utilisées ou subir un traitement supplémentaire. Une ou plusieurs couches de bandes continues sont transmises à une zone de chauffage où les bandes (42) sont maintenues dans une voie prédéterminée à mesure qu'un fluide de chauffage passe rapidement à travers des bandes. La température, la pression et le débit volumétrique du fluide de chauffage sont réglés de façon à assurer de façon appropriée la décomposition du liant et l'évacuation rapide des produits de décomposition loin des bandes afin d'empêcher une accumulation de chaleur qui pourrait augmenter la température jusqu'au point de fusion des fibres. Les températures de traitement sont ainsi maintenues de façon appropriée au-dessous de la température de fusion du matériau des fibres. Les fibres récupérées peuvent être directement recyclées, recevoir un traitement supplémentaire si souhaité ou, dans le cas où des niveauxinacceptables de liant soient encore présents sur les fibres, ces fibres non-récupérables peuvent être déchargées afin d'être jetées ultérieurement. Les produits de la décomposition du liant sont incinérés et forment une partie du fluide de chauffage passant à travers les bandes.
Abstract:
A method and apparatus for directing a stream (15) of bulk fibers while simultaneously spraying an inorganic temperature resistant tacky binder material into the stream (15) of fibers. A layer of high temperature insulating fibers may thus be formed. The binder may be a phosphate tackifying agent mixture or a colloidal suspension of materials with the tackifying agent. The takifying agent is preferably montmorillonite clay. Spray gun (14) is employed to direct the refractory fiber stream (24) through conduit (23) so as to emerge from an annular path defined by deflector body (25) and manifold (26).
Abstract:
A method of making and the resulting diatomite-modified pavement. The addition of small amounts (0.5 to 2%) diatomite by weight to conventional pavement mixes, serves to increase density, viscosity, aggregate interlock and temporarily volumetrically extends the asphalt improving compactability resulting in an emplaced pavement that has lower air and water permeability without increased instability. The improved strength of the mixed and abrasion resistance of the mastic enable the thickness of wearing course overlays to be reduced without detrimental effects of wear life. The addition of diatomite makes the pavement mix more forgiving of errors in asphalt and aggregate amounts and can result in significant reduction of cost/sq. yard of pavement.
