Abstract: A puncture resistant pneumatic tire has a tread portion and a pair of lateral tread edges. A belt package is located radially inward of the tread portion and a carcass structure has at least one body ply which extends between and is turned up around a pair of bead cores. A protective band extends circumferentially about the tire radially beneath the tread portion and includes a plurality of circumferentially spaced metal rods, each of which extends in a lateral direction between the tread edges. The protective band may be located radially inward or outward of a spiral ply layer and the rods may be arranged in a staggered laterally offset layered relationship. The rods have a circular cross-section with a diameter of between 1/16 inch and ¼ inch and a length of between 7 inches and 8 inches and will deflect and dislodge the pointed end of road debris before it completely punctures the tire.

Abstract: A plastic container having enhanced insulation is made from a partially-laminated billet having a laminated outer periphery and gas trapped between the unlaminated portion of the billet layers, by heating the billet to a temperature below the softening point of at least one of the layers, which expands the gas trapped between the layers and separates the unlaminated layers. The billet is then clamped about its outer periphery and drawn into the shape of the container using solid-phase forming techniques. The separated layers insulate the contents of the container from the surrounding environment.

Abstract: A process is disclosed for the fabrication of a thermoplastic container having a lid bonded thereto. The container and lid are formed from laminated thermoplastics wherein at least one of the layers that forms the laminate is dielectrically heatable. The heatable layers of the cup and lid are placed in contact with one another, dielectrically heated, and melt together to form a continuous bonded area or lid seam between the cup and lid. The materials of the cup and lid are selected such that the resultant bonded area forms an exygen barrier between the contents of the container and the outside environment. The strength of the bonded area is selected such that the lid may be manually-removed from the container.

Abstract: Four different versions of multi-position selector switches can be assembled from a kit of parts by selecting various combinations of the parts and assembling them into a housing consisting of an insulating case and cover. Inventory of parts is reduced by mutual use of some parts in two or more versions. The possible selector switch versions are a three position selector switch having three momentary pushbuttons for selectively closing two normally open contacts and opening a normally closed contact a two-position slector switch having two momentary pushbuttons for selectably closing a normally open contact or opening a normally closed contact, a three-position selector switch having three maintainable pushbuttons for selectively closing two normally open contacts and opening the same, and a three-position selector switch having three pushbuttons including a momentary pushbutton and two maintainable pushbuttons for selectively closing two normally open contacts and for opening the maintained contact. The third and fourth versions described above which have maintainable pushbuttons comprise one or two sliding interlock members having cam surfaces cooperating with respective pushbuttons for preventing depression of more than one pushbutton at a time, and a holding plate for releasably retaining the pushbuttons depressed until the latter are returned to an extended position by one of the sliding interlock members.

Abstract: A method and system for purifying production water obtained from oil and gas operations so that the purified water need not be disposed of by forced injection back into the geological formation but can be put to a beneficial use such as agriculture, irrigation, industrial or municipal or potable applications. The production water is treated in a ceramic microfilter after it has been pretreated (preferably by aeration and with a walnut shell filter) to remove volatile hydrocarbons and heavier oils, such as paraffins and asphaltenes, that could foul the ceramic filter. The permeate from the ceramic microfiltration can then be treated with activated charcoal or otherwise treated to meet the specific requirements for the intended beneficial use.

Abstract: A thermoplastic laminated billet is made by dielectrically heating a stack of thermoplastic layers within a mold press, wherein the sequence of dielectrically heatable and non-heatable individual layers is such that no more than a tie layer separates a heatable and non-heatable layer so that only that portion of the non-heatable layer nearest the heatable layer or layer melts. The laminated billet is formed within the mold press that has electrodes formed therein, the electrodes capable of impressing on the dielectrically heatable layers used to form the laminated billet sufficient energy to melt the heatable layers and at least a portion of the adjacent non-heatable layers.
