Abstract: A direct-sequence multiple-access code division (DS-CDMA) communication system accommodates a multiplicity of separate transmitters (12) and at least one base-station receiver (14). Each transmitter generates a transmitted signal (16) at a common carrier frequency. Each transmitter has an assigned spreading code. Each bit time within the transmitted signal includes a unique signature waveform (21) generated from the spreading code that identifies the source of the transmitted signal. For a given transmitter, the transmitted signals from the other transmitters represent "multi-access noise" that may adversely degrade the signal-to-noise ratio (SNR) of that transmitter's signal at the receiver. Each transmitter operates using a spectrally inefficient power spectrum, i.e., a non-flat power spectrum, that simplifies the transmitter circuits.

Abstract: Crystalline aluminumphosphate compositions having three-dimensional microporous crystal framework structures whose chemical composition expressed in terms of mole ratios is Al.sub.2 O.sub.3 :1.0.+-.P.sub.2 O.sub.5 are disclosed. These compositions have an X-ray diffraction pattern characterized by d spacings at less than about 40 degrees two-theta as measured using copper K-alpha radiation that are substantially as shown in Table 1. The compositions can further comprise a structure-directing agent. Preparation is by admixing an aluminum source, a phosphorus source and 10-100 moles of water per mole of Al.sub.2 O.sub.3 to form a precursor mixture, admixing the precursor mixture with the structure-directing agent to form a reaction mixture, and reacting the reaction mixture under conditions such that an aluminumphosphate composition of the given X-ray diffraction pattern is formed.

Abstract: A method and recording for use in achieving Alpha and Theta brain wave states and effecting positive emotional states in humans to enhance learning and self-improvement, is provided which includes a medium having a musical composition recorded thereon with an initial tempo decreasing to a final tempo and verbal phrases, comprising between approximately 4 and approximately 8 words, recorded in synchrony with the decreasing initial tempo.

Abstract: A substantially nitrate-free solution for milling products of refractory metals, especially titanium, which milling solution comprises: (a) about 20-100 g/l hydrofluoric acid; (b) a hydrogen inhibitor selected from the group comprising of: about 55-650 g/l of sodium chlorate, about 180-650 g/l of ammonium peroxysulfate, and at least about 10 g/l of hydrogen peroxide; and (c) a balance of water and impurities. A method for chemically milling, etching and/or pickling metal products, such as titanium alloy forgings, with the aforementioned solution is also disclosed.

Abstract: A bowling lane maintenance machine (10) performs selected maintenance operations on the surface of the bowling lane, shifts itself to the approach area spanning a plurality of lanes behind the foul line end of the lanes, indexes to another lane, and then shifts to the lane to again perform a maintenance operation thereon. The machine (10) includes structural housing (12) cleaning maintenance assembly (14), propulsion assembly (16), and electronic control system (18); which cooperate for controlled maintenance operations as described above.

Abstract: The oil pattern laid down by the automatic machine across the width of the lane and along the length of the lane can be precisely controlled and varied through the use of a series of independently controllable wick assemblies that are individually movable into and out of contacting engagement with the oil applicator of the machine. A programmable controller for the wick assemblies determines which of the wick assemblies will be in oil-transferring contact with the applicator and when.

Abstract: Crystalline compositions, e.g. zincosilicates, which contain 3-membered rings and have a framework density (FD) of less than 21 tetrahedral atoms per cubic nanometer, and their method of preparation are disclosed. The compositions may be used as ion-exchangers, adsorbents, catalysts, e.g. hydrocarbon conversion catalysts, and catalyst supports.

Abstract: Crystalline metalloaluminophosphate compositions having pore windows formed by 18 tetrahedral members are prepared from a forming mixture containing sources of aluminum, phosphorus and a non-aluminum, non-phosphorus element, e.g. boron or boron and silicon. The forming mixture further contains a directing agent comprising a mixture of quaternary nitrogen compound and amine in a molar ratio of 0.01 to 0.025.

Abstract: Crystalline aluminophosphate compositions having pore windows formed by 18 tetrahedral members are prepared from a forming mixture containing sources of aluminum, phosphorus and optionally, silicon. The forming mixture further contains a directing agent comprising a mixture of quaternary nitrogen compound and amine in a molar ratio of 0.01 to 0.025. The resulting product exhibits greater stability than compositions made from amine directing agent.

Abstract: This invention relates to a catalyst comprising a solid surface having immobilized thereon an aqueous solution of one or more organic complexes of rhodium. The catalyst is useful for promoting hydroformylation, hydrogenation and other chemical reactions in essentially water-immiscible organic liquid reactant phases.

Abstract: A process for the hydroformylation of alkenes and other olefinically unsaturated reactants by reaction with carbon monoxide and hydrogen in the presence of a heterogeneous catalyst comprising a solid surface having immobilized thereon a solution of one or more rhodium complexes which is essentially immiscible with the organic reactant. Catalyst is subsequently recovered from the resulting hydroformylation product by one or more solid-liquid separation techniques.

Abstract: A tray for a child's car seat, wherein tension coil springs are used to retain the tray in a position spanning the space between the car seat arm rests. Two laterally spaced leg structures depend from the tray to engage upper surfaces of the arm rests in such fashion as to prevent lateral dislocation of the tray from its installed position. The tray may be quickly removed from the car seat without special tools.

Abstract: Powdered detergent compositions containing a surfactant, fillers, builders and the like, can be prepared by removing water from the detergent composition to form the powder. Frequently, such powdered detergent compositions are hygroscopic and lose the free-flowing characteristics upon storage. According to the present invention, a detergent composition which comprises at least 5 percent by weight of a mixture of alkyl benzene sulfonates wherein greater than 55 mole percent of the alkyl benzene sulfonates have alkyl chains of greater than 11 carbon atoms, the alkyl chains having 12 or more carbon atoms have a 2-phenyl content greater than 60 percent of the total 2-phenyl content, along with other detergent ingredients are provided which provides a free-flowing dry composition that is less hygroscopic than prior art products.
