Title: Process for preparing an aroma product containing alpha-acetolactic acid
Inventor: VERHUE WALTER M M
IPC: A23L27/24
Filed: 1991-08-12
Granted: 2000-10-31
Abstract: A process is provided for preparing an aroma product containing a high concentration of .alpha.-acetolactic acid, a precursor of the flavour component diacetyl, by subjecting at least one food product constituent to lactic acid bacteria which are in their stationary growth phase, particularly to a cell-free extract or cell lysate of lactic acid bacteria. The food product constituent can be citric acid, lactic acid and especially pyruvic acid or mixtures thereof. The pyruvic acid can be obtained by culturing a bacterium of the genus Propionibacterium, e.g. Propionibacterium freudenreichii.     Suitable lactic acid bacteria include Lactococcus lactis, particularly subspecies lactis and its biovar diacetilactis, and Leuconostoc cremoris.

Title: Earthing switch for a metal-encapsulated high-voltage switchboard plant insulated by pressurised gas
Inventor: LORENZ DIETER
IPC: H01H31/00
Filed: 1990-08-14
Granted: 1997-06-10
Abstract: In a grounding switch for an encased high-voltage switching system, the movable switching piece is moved by a rotating drive shaft, which passes through the housing of the grounding switch.  In order to design the contact elements, which transfer the ground potential to the movable switching piece, in as simple a manner as possible, the drive shaft consists of electrically conductive material and is introduced into the housing in an insulated manner.  The drive shaft is connected with means to transfer the ground potential, e.g. a current strip, outside the housing.  The drive shaft therefore serves both to transfer force and to transfer potential.  A switch blade is designed to be elastically deformable in part and serves as the movable switching piece.  Such a grounding switch for an encased, compressed-gas-insulated high-voltage switching system can thus be used also as an insulated grounding switch, to carry out measurements.

Title: Gps precision approach and landing system for aircraft
Inventor: BROWN ALISON K
IPC: B64D45/04
Filed: 1993-09-09
Granted: 2002-11-19
Abstract: A GPS precision approach and landing system for aircraft employs a fixed ground facility and a single satellite navigation receiver on board the aircraft. The fixed ground facility includes a reference receiver that measures differential corrections to the satellite code and carrier measurements and a pseudolite that is employed to transmit these corrections to a broadband GPS receiver on board the aircraft and to provide an additional code and carrier measurement to assist in the navigation solution. The pseudolite signal is broadcast at a frequency offset from the L1 GPS frequency in order to prevent interference with the satellite navigation system. The broadband GPS receiver on board the aircraft is capable of making phase coherent measurements from the GPS satellites, the pseudolite signal, and the GLONASS satellites. These phase coherent measurements are combined to form a precise differential carrier ranging (DCR) solution that is used to provide three-dimensional position guidance of the aircraft throughout a precision approach and landing procedure.

Granted: 2004-08-03
Abstract: An erase unit for an ion deposition web-fed print engine includes a plenum extending the width of the electrostatic image on the image cylinder and defining an information chamber with the image cylinder surface. The plenum has first and second electrodes separated by a dielectric. Upon application of a time-varying potential having a frequency of 0.2 to 50 mHz across the electrodes, ionization occurs, causing an ion current flowing in relation to the image surface until the image surface and the biasing electrode are at the same potential, thus erasing any residual electrostatic image on the cylindrical surface. By providing a DC biasing voltage, the residual electrostatic image may be erased when equalization occurs, with the image cylinder maintaining a pre-charged potential.

Title: Method and apparatus for non-invasive measurement of blood sugar level
Inventor: KOASHI KATSUE
IPC: A61B5/00
Filed: 1993-08-12
Granted: 2004-04-06
Abstract: Laser light is periodically intensity and wavelength modulated. This light is separated into two optical paths.      One irradiates an examined portion of skin for assessing blood sugar. A first detector detects the intensity of transmitted or reflected light from examined portion, while the intensity of the laser light passing through the second path is detected by a second detector. The ratio of the former intensity to the latter intensity is determined by a logarithmic ratio amplifier. The rate of change in the ratio with respect to the change in wavelength of the wavelength modulation is determined by a lock-in amplifier to obtain a derivative spectral signal of the absorption spectrum of glucose. An arithmetic processor detects the blood sugar in the examined portion from the derivative spectrum.

Abstract: T-DNA tagging with a promoterless .beta.-glucuronidase (GUS) gene generated a transgenic Nicotiana tabacum plant that expressed GUS activity only in developing seed coats. Cloning and deletion analysis of the GUS fusion revealed that the promoter responsible for seed coat specificity was located in the plant DNA proximal to the GUS gene.      Analysis of the region demonstrated that the seed coat-specificity of GUS expression in this transgenic plant resulted from T DNA insertion next to a cryptic promoter. This promotor is useful in controlling the expression of genes to the developing seed coat in plant seeds.
