Patent GB-2328018-A (GB)
Title: DSP technique for photo-acoustic spectroscopy (PAS)
Inventor: CURBELO RAUL
IPC: G01N21/00
Filed: 1998-08-05
Abstract: A technique for extracting the impulse response of a sample of interest includes corresponding measurements made with the sample of interest and a reference sample. At each of a series of steps in an FT-IR spectrometer, the sample of interest is illuminated with an excitation pulse of infrared radiation, acoustic signals having a time dependence os(t) arising from the excitation pulse are captured, and a Fourier transform Os of os(t) is computed. At each of a series of steps in the FT-IR spectrometer, the reference sample is illuminated with an excitation pulse of analytic radiation, acoustic signals having a time dependence OR(t) arising from the excitation pulse are captured, and a Fourier transform OR of OR(t) is computed. For each step, an inverse Fourier transform of the ratio OS/OR is computed to provide a series of values s(ti) for a series of times ti. These values s(ti) represent the impulse response s(t) of the sample of interest for the mix of optical frequencies for that retardation value. Interferograms are processed to provide photoacoustic spectra.

Title: Speed control system for vehicle
Inventor: BEEVER PAUL ADRIAN
IPC: B60W10/18
Filed: 1999-09-01
Abstract: When the system is activated by switch 38, drive means 34, 36 and brake system 16, 18, 20 are controlled by speed control unit 22 to provide the level of acceleration or retardation demanded by accelerator pedal 30 or brake pedal 32, both of which are connected to the speed control unit 22. Each of a range of positions of the accelerator has an associated target speed, and the drive means or brake system are controlled to bring the vehicle speed towards the target speed at a rate which depends on the difference between the actual speed and the desired speed, with a greater difference being associated with a greater rate of change. The system may also control the transmission and may disconnect the engine from the vehicle wheels to enable the speed control to reduce the vehicle speed to zero while the engine is running. The target speed may vary with the drive ratio selected. The system may be used to control the descent of hills, particularly for off-road vehicles.

Title: Adhesion promotion
Inventor: LEACH ROGER JOHN
IPC: C03C23/00
Filed: 1999-10-08
Abstract: Adhesion of a thermosetting powder coating to a glass substrate surface using a silane adhesion promoter, is enhanced by modifying the pH of the glass surface to between 3.5 and 5, prior to, or during, the action of the promoter. The pH-modification may be effected during washing of the surface prior to spray-application of the promoter, or by including an acid or alkali modifier in the silane solution. Alternatively, the silane, or the silane and the modifier, may be included in the thermosetting powder to become active during fusing of the powder to the glass surface. An acid or alkali solution dried on the surface prior to application of the promoter for activation with the promoter on heating, may be used instead or in addition.

Title: Method and apparatus for increasing efficiency and productivity in a power generation cycle
Inventor: KAKOVITCH THOMAS
IPC: F01K25/06
Filed: 1993-08-12
Abstract: A method and apparatus for converting heat energy to mechanical energy with greater efficiency. According to the method, heat energy is applied to a working fluid in a reservoir sufficient to convert the working fluid to a vapor and the working fluid is passed in vapor form to means such as a generator for converting the energy therein to mechanical work. The working fluid is then recycled to the reservoir. In order to increase the efficiency of this process, a gas having a molecular weight no greater than the approximate molecular weight of the working fluid is added to the working fluid in the reservoir, separated from the working fluid downstream from the reservoir, compressed and returned to the reservoir.

Title: Specifically crosslinked hemoglobin with free functionality
Inventor: KLUGER RONALD
IPC: A61K47/48
Filed: 1993-11-12
Abstract: Hemoglobin is site-specifically crosslinked into its tetrameric form by reaction with a trifunctional reagent which combines electrostatic effects, steric effects and the presence of functional groups so that two of the functional groups react with specific sites on the hemoglobin whilst the third site is left free for reaction with endogenous nucleophilic compounds. A specific example of such a crosslinking reagent is trimesoyl tris(3,5-dibromosalicylate), TTDS, which effects specific crosslinking between the amino groups of lysine-82 on each respective  beta  sub-unit. While the crosslinking reagent TTDS has three available carboxyl groups for the crosslinking reaction, only two so react, leaving one free carboxyl for reaction with exogenous nucleophiles, e.g. to render the hemoglobin product useful as a carrier for nucleophilic compounds through the body's circulatory system.
