Title: Process for the synthesis of a layered clay-like material as well as its use
Inventor: HOOYKAAS CAREL W J
IPC: C01B33/40
Filed: 1993-12-06
Abstract: ABSTRACT OF THE DISCLOSURE            A process for the synthesis of a layered, clay-like material as well as its use.      The invention relates to a process for the synthesis of a layered, clay-like material starting from a silicon oxide containing material in a finely divided state by reacting a glass phase containing material at a pH from 5 to 8, in the presence of water, with a source of layer-forming metal ions and an activator for the formation of clay under atmospheric conditions to obtain a material with a stable structure. Preferably aluminium and/or magnesium ions are employed as layer-forming metal ions. Furthermore, according to a suitable embodiment, boron glass or cullet is employed as a material containing silicon oxide. The conversion of the mixture of materials into a substance having an ordered structure takes place preferably at a pH of approximately 7 and a temperature of 30-45 °C, in which the starting materials appropriately have a particle size of approximately 100 microns. An activator for the formation of clay is added to accelerate the process of conversion. Moreover, if desired, a clay modifier can be added. As starting mixture, a hearth ash containing a glass fraction obtained by incinerating household and industrial waste can be employed; this hearth ash proves to be a useful secondary raw material. By means of the present process waste material, whether subjected to incineration or not, that has been polluted with inorganic material can be immobilized.

Title: Method of high mass resolution scanning of an ion trap mass spectrometer
Inventor: WELLS GREGORY J
IPC: H01J49/42
Filed: 1994-05-19
Abstract: A method of using a quadrupole ion trap mass spectrometer for high resolution mass spectroscopy is disclosed. High resolution of a mass spectrum of a desired species is achieved by first using a slow scanning rate and by first ridding the trap of unwanted ions. Accurate mass calibration is achieved by using a reference compound of known mass and using a second supplemental AC dipole voltage to eject the reference ions at nearly the same time as the sample ions of interest are ejected from the trap. This eliminates the need to scan the trap between the masses of the sample and reference ions. Space charge in the trap is held constant, thereby eliminating a major source of mass axis instability, by using the results of one scan to control the ionization time during the next scan. Preferably, during ionization a broadband supplemental dipole voltage is applied to the ion trap to rid it of unwanted ions. During a portion of the ionization time the broadband signal is constructed to retain only sample ions in the ion trap, and during the remainder of the ionization time the broadband signal is constructed to retain both sample and reference ions in the ion trap. By adjusting the relative lengths of the two portions of the ionization time the total space charge in the ion trap can be held constant notwithstanding variations in sample ion concentration.

Title: Jaw builder
Inventor: MCGUNIGAL GREGORY T
IPC: A63B21/02
Filed: 1994-07-18
Abstract: In other tools for muscle building it is known that a muscle must be worked through the fullest range of movement/motion as possible against resistance.  In this invention the device/tool is to work the mandible muscles through opening and closing the mouth as far apart as possible.  This device allows this as the lower mouthpiece may be executed through a large range of motion.  This mouthpiece moves the metal rod and the sliding metal piece connected to it in harmony creating resistance from the separation of the stationary metal rods resistance band attachment against the sliding vertical metal pieces resistance band attachment.  Progressive resistance is also fundamental to building muscles and the different strength resistance bands (in designated positions) should supply this necessary requirement.  The metals connected to the lower mouthpiece may be elongated to further this effect.     In essence, as the mouth closes (with the mouthpieces in place) it activates the other parts of the device whereby specialized resistance bands are stretched simulating resistance loads.  Springs or cords might be used in place of resistance bands.

Title: Method of determining the zero dispersion wavelength of an optical waveguide
Inventor: VEITH GUSTAV
IPC: G01M11/00
Filed: 1995-03-29
Abstract: It is necessary to know the zero dispersion wavelength .lambda.0, to ensure the reliable transmission of high bit-rate frequency signals via remote transmissionpaths. The method for determining the zero dispersion wavelength of an optical waveguide knowingly utilizes a disturbing effect that is undesirable in optical communications transmission techniques, which is able to lower the transmission quality. This effect is the so-called four-wave mixing, or in special cases a partially degenerated four-wave mixing. The method couples two light signals of different wavelengths (.lambda.1, .lambda.2) into an optical waveguide (4). A mixing product which occurs in the optical waveguide as a result of a partially degenerated four-wave mixing is evaluated by an analyzer (3). The wavelength of one of the two light signals is selectively varied until the optical output of the mixing product reaches a maximum. At that point the wavelength of this light signal coincides with the zero dispersion wavelength .lambdaØ

Abstract: COMPOSITE POLYMER DEVICES FOR CONTROLLED        RELEASE OF SEMIOCHEMICALS                ABSTRACT OF THE DISCLOSURE           Composite   polymer   dispensers   capable   of controlled release of semiochemicals have been developed. The  dispensers  make  use  of  a  solid  elasomer  matrix reservoir which is at least partially surrounded by release rate controlling polymer membrane.   The matrix materials are   polyurethanes   compatible   with  many   types   of semiochemicals  and  additives.    The  release  rates  of semiochemicals from the dispensers can be varied over a wide range by manipulation of the reservoir conditions and by selection  of the type of polymer membrane surrounding the device.  The dispensers can have a variety of forms and can be produced by a simple process.   The semiochemical devices produced by this method are useful for managing insect and other pests through attraction to traps,  for population monitoring or for mass trapping.  The devices may also be used to dispense anti-aggregation pheromones or repellents in addition to use for mating confusion or disruption.
