Abstract: An interactive display arrangement in a telephone terminal permits direct movement between unrelated child menu screens in a menu hierarchy. The arrangement is configured such that a user may advance directly from a displayedfirst child menu screen to an unrelated second child menu screen in the menu hierarchy, in order to perform specific tasks at the second child menu screen. Once the tasks at the second menu screen are completed or the user elects not to perform such tasks, the arrangement permits the user to return directly to the first child menu screen. The user of the telephone terminal thus is able to easily complete specific tasks at selected menu screens in the interactive display arrangement without the need for excessive movement in the menu hierarchy.

Title: Method for capturing ecologically harmful substances from material polluted with such substances
Inventor: HOOYKAAS CAREL W J
IPC: B01J20/12
Filed: 1994-05-27
Abstract: ABSTRACT OF THE DISCLOSURE         A method is described for capturing ecologically harmful substances, both of organic and inorganic nature, by absorbing these substances on a zeolite or on a swellable, layered clay which has been modified with hydroxyaluminium to form an aluminium-rich zeolite or a pillared clay containing pillars of aluminium hydroxide complexes, said aluminium-rich zeolite or aluminium-pillared cationic or anionic clay having been treated, prior to the absorption, with a salt of an inorganic acid, preferably with a phosphate. If the treatment is carried out with a salt of a rare earth element, superpillars are formed in the clay, as a result of which a clay having a great absorbency in addition to a large rate of flow is obtained. By treating the pillared clay with a quaternary ammonium compound, a doubly modified clay is formed which is exceedingly suitable for treating material which has been polluted with a combination of organic and inorganic ecologically harmful substances, and in particular polluted with heavy metals.

Title: Method for producing a precise alloy composition from input variables under nonlinear incorporation conditions
Inventor: CUNNINGHAM JOHN E
IPC: H01L21/20
Filed: 1994-06-06
Abstract: A Method for Producing a Precise Alloy Composition From Input Variables Under Nonlinear Incorporation Conditions Abstract:   A process for manufacturing precise alloy compositions in nonlinear alloy systems. The invention implements a new quadratic fitting function that relates alloy composition CA for a variable A to input fluxes fA and fB, as cA=fA2/(fA2+.beta.fB2). .beta. is a parameter that is used to modify the incorporation of the Group V input variable B. This modification is necessary because of different surface populations of Group V dimer species. This new fitting function precisely predicts alloy compositions in nonlinear systems, such as the GaAs1-yPy system, where y is set equal to the composition cA.

Title: Method of synchronization for code division multiple access radiotelephone communications
Inventor: LUCAS PHILIPPE
IPC: H04B1/707
Filed: 1994-06-14
Abstract: The synchronization method consists in selecting, at a mobile station, at least one periodic pseudorandom sequence (PN) which corresponds to and is synchronized with the reference sequence transmitted by a base station on a pilot channel, and received by the mobile station over a propagation path, with this being done regardless of the frequency deviation between the transmitter and the receiver. Various possible sequences are tested by calculating the quantities E[s(t).s*(t-~)] and E[s(t).s*(t)], where E(.] designates the mean value calculated over a predetermined integration time, ~ designates a predetermined delay, and s(t) = r(t).c(t) designates the product of the received base band signal r(t) by the value (c(t)} of the tested sequence, and by calculating the ratio ¦E[s(t).s*(t-~)]¦ / E(s(t).s*(t)]. The sequence under test is selected if said ratio exceeds a predetermined threshold.

Abstract: A preamplification and impedance matching circuit for an electromagnetic acoustic transducer includes an impedance matching section of the circuit having input terminals for receiving radio frequency power from a radio frequency power source.  A matching transformer, which is a step-down transformer, is operatively connected to the input terminals.  Diode networks are operatively connected to the matching transformer and output terminals which lead to the coil of the transducer.  Signal responses emitted by the transducer coil are transmitted to a preamplifier section of the circuit.  Choke coils or resistors are used to limit radio frequency power entry into the preamplifier section of the circuit.  The preamplifier section has a preamplifier which is operatively connected to a first transformer and a second transformer such that the transformer are located on opposite sides of the preamplifier for increasing the amplitude of the coil signal response prior to transmission to detectors located in the instrumentation of the transducer.

Title: Somatotropin modifications
Inventor: LEHRMAN S RUSS
IPC: C12N15/09
Filed: 1993-10-04
Abstract: Somatotropin modifications are described that have unexpected enhancements in conformational and chemical stability without loss of bioactivity. Alterations of these characteristics are obtained via modification of somatotropins by site-directed mu-tagenesis. These changes increase the storage stability of these proteins. Exemplary modifications include poreine somatotropins having histidine and arginine substitutions for glutamine and histidine at positions 19 and 20, respectively (Q19H, H20R), having glutamic acid substituted for phenylalanine at position 52 (F52E), and having glutamic acid substituted for leucine at position 137 (1137E). The modified somatotropins are useful to enhance growth characteristics in animal species, e.g., to increase the lean-to-fat ratio in pigs and milk production in cows.

Title: Improved liquid decontamination apparatus and method

Filed: 1994-01-21
Abstract: In a multi-pass system for purifying oil or other liquids, an improved apparatus and method for mixing air with the contaminated liquid for separation after a phase change from liquid to gas. The contaminated liquid is drawn from areservoir (10) by a pump (14), filtered (18), and heated (20), and atmospheric air is induced into the contaminated liquid downstream of the heater by an eductor (22,50) which promotes the phase change from liquid to vapor. The liquid/contaminant mix, which now includes entrained air, is passed immediately through a second eductor (22,60), the compressibility of the air in the mix, followed by expansion of the compressed air as the mix exits the second eductor,causing intimate contact of air and contaminant, thereby promoting the strippingof the contaminant from the liquid. The air/liquid/contaminant mix is then routed to a level controlled separation tank (24), water vapor, contaminants, and condensate being released from the tank in the space above the pooled liquid. Purified, dry liquid is drawn from the tank by a second pump (14) and delivered back to the reservoir.
