Abstract: The present invention is directed to a thermosetting coating composition for improving the scratch resistance, blush resistance, and lubricity of glass surfaces (e.g., glass bottles), and in certain instances also improving the label adhesion of coatings derived therefrom which comprises as functional ingredients a polyamine terminated polyepoxide adduct salt, an epoxy crosslinker, a reactive silane, a surfactant, and a natural or synthetic wax. The coating composition is carried in a vehicle which comprises water and a suitable co-solvent. The combination of the adduct salt and co-solvent permits the microemulsification of the epoxy crosslinker. The wax is also present in the emulsified state.

Abstract: Concretes containing a hydratable cementitious binder such as Portland cement and a high strength aggregate material are described. The high strength aggregate material is produced from hydrated cementitious compositions which contain relatively low proportions of Portland cement and relatively high proportions of a select fly ash component. The high strength aggregate material is produced by mixing the aforementioned Portland cement and fly ash components with water and allowing such to hydrate. The hydrated aggregate product may then be reduced in size (e.g. by crushing) and screened prior to combination with the cementitious binder to produce concrete compositions. Concretes can be prepared with such aggregate which have at least comparable compressive strengths to concrete prepared using conventional crushed stone aggregate.

Abstract: Vandalism and robbery of parking meters have become big problems. The unauthorized entry into the coin box area or striking of the housing as well as bending the support pipe makes it desirable to apprehend the robbers and/or vandals. Repair of the parking meter or support may be required due to such vandalism. A radio transmitter is adapted to send simultaneously two signals to a receiver which is constantly "on". The received signal indicates unauthorized entry or vandalism to a parking meter and to the particular parking meter from which the signal is sent. Switches are actuated at an opening of the timer compartment and/or coin box area. A switch is also actuated when the supporting post is bent. A timer is placed in this circuit so that only after a determined time interval is a signal sent of the bending of a post. On new installations a tensioned wire is placed in the pipe and is actuated when the pipe is cut or severely bent.

Abstract: Concretes containing Portland cement, fly ash and aggregate are disclosed which are capable of attaining high compressive strength and which contain relatively low proportions of Portland cement and relatively high proportions of a select fly ash component. The inventive concretes may be formulated as highly dense masses particularly suited for use in the manner of conventional structural concretes in buildings, bridges, dams, etc. Comparatively low density concrete masses may also be produced which are light in weight and have thermal insulation value rendering them particularly suited for use as thermal insulating components of roofs and as protective coatings for a variety of substrates.

Abstract: A remote sensor for the measurement of the amount of gas present in the drilling fluid or "mud" in an offshore well-drilling operation, for the purpose of giving prompt warning of geologic conditions conducive to the occurrence of a blow-out. An acoustic projector projects an acoustic wave of fixed wavelength through the mud returning upwardly from the borehole. The wave is received by a first array of acoustic receivers locked in a known phase relationship with the projector. Changes in the speed of sound due to changing relative amounts of mud and gas produce a shift in frequency of the acoustic wave which is proportional to the speed of sound in the mud/gas mixture. The change in frequency is electronically detected and scaled to yield the value of the speed of sound, from which the mud to gas mass ratio is calculated by means of a computer.

Abstract: Stimulation of oleoresin production associated with living cells can be chemically induced with dilute systemic application of ethylene or ethylene-releasing compounds. One such ethylene-releasing compound is 2-chloroethylphosphonic acid. A further increase in oleoresin production can be accomplished by using ethylene-releasing chemicals in combination with the bipyridilium salts, diquat or paraquat. Through the application of ethylene-releasing chemicals in combination with a bipyridilium salt, the effect of lightwood inducing chemicals is expanded over a larger portion of the treated tree, and more oleoresin is produced. Oleoresins are extracted from the trees by known methods, and the naval stores products are recovered therefrom.

Abstract: A medium density, high strength lignocellulose composition board comprises on a dry weight basis from 60 to 95% lignocellulose particles and from 5 to 40% exhaustively hydrated cellulosic gel binder, the gel binder being characterized in its gel condition by a TAPPI drain time of at least 350 seconds.

Abstract: Cellulosic pulp is made in 85% yield by mechanically defiberizing lignocellulose in a steam atmosphere, mixing the resulting aqueous fibrous pulp with a lignocellulose-pulping quantity of finely divided lime, and digesting the pulp in the presence of the lime to a predetermined degree of pulp digestion. The resulting digested fiber can then be mechanically beated in aqueous medium until it is substantially converted to a hydrated cellulosic gel product.

Abstract: A fire resistant bauxite composition board comprises, in percent by weight, from 10 to 85% lignocellulose particles, from 65 to 20% bauxite particles, and from 5 to 25% binder, particularly a hydrated cellulosic gel binder. The bauxite, (aluminum oxide dihydrate), is characterized by containing a large amount of water of hydration, by stability below 200.degree. C., and by release of its water of hydration at above 200.degree. C. Accordingly, the bauxite-containing board is stable during its manufacture, storage and use. However, in a fire situation the substantial amount of released water of hydration materially supplements the inherent non-combustible character of the bauxite in increasing the fire resistance of the board.

Abstract: A system is disclosed for marketing merchandise or services by telephone using brief prerecorded audio demonstrations stored in an audio program repeater and connected to a customer's telephone line by a switching system under control of a data processor in response to a code entered by a customer service operator via the switching system or a code entered directly by the customer through his push-button telephone. In the latter case the data processor is in direct communication with the customer who uses the telephone push buttons to respond to prerecorded messages transmitted from the audio program repeater under control of the data processor. Otherwise the customer communicates with a customer service operator through the switching system and the customer service operator in turn selects the demonstration through the data processor.

Abstract: A collimated hole structure formed by constricting a plurality of tubular elements each provided with a core for supporting the tubular element during the constricting operation. The bundle of elements is constricted to a point where the elements effectively fuse into a substantially monolithic body. The cores are then removed, leaving a plurality of extremely small diameter, generally parallel passages in a solid body. The tubular elements may be arranged in any desired array, and thus the passages may be provided similarly in any desired array. The passages may have high aspect ratios and may be closely juxtaposed. In one illustrative application, the collimated hole structure is provided with dielectric film and utilized as an anode portion of an electrolytic capacitor. In another illustrative application, the collimated hole structure is utilized as a tip for a drilling device.

Abstract: A fire resistant vermiculite composition board comprises, in percent by weight, from 40 to 90% heat expanded vermiculite particles; from 5 to 20% ceramic clay particles; from 10 to 30% hydrated cellulosic gel having a TAPPI drainage time of at least 900 seconds; from 1 to 20% defiberized wood; and from 1 to 20% starch. The vermiculite is in an incompletely expanded condition of a degree predetermined to permit its further expansion upon subsequent exposure to heat. This results in a corresponding expansion of the composition board of which it is a component when the board is exposed to fire, preventing the formation of cracks and insuring continued fire protecting coverage of the area across which the board is applied.
