Patent GB-2204640-A (GB)
Title: I.C. engine fuel injection nozzle
Inventor: GASKELL DAVID JOHN
IPC: F02M61/16
Filed: 1988-05-05
Abstract: The valve member (16) is biased by a pair of springs 26, 27 which act against the opposite ends of a beam 24 which is pivotally mounted on the valve member. The stronger spring 27 is a preloaded spring and the initial movement of the valve member away from the seating is against the action of the weaker spring 26. A stop 29 limits the initial movement of the valve member so that a restricted flow of fuel takes place. The valve member moves further against the stronger spring alone when the fuel pressure is further increased. Alternative arrangements for varying the spring load and maximum spring compression by valve lift are described (Figs. 2 to 4). <IMAGE>

Patent GB-2223176-A (GB)
Title: A roller skate
Inventor: YU CHUNG-HSIUNG
IPC: A63C17/04
Filed: 1988-09-30
Abstract: This invention discloses a roller skate comprising at least one front roller (30, 31), a middle roller (40) longitudinally aligned with the front roller (30, 31), and a pair of rear rollers (50). The lowest point of the front roller (30, 31) is substantially higher than the middle roller (40) and the pair of rear rollers (50) so that a skater can skate only with the front roller (30, 31) and the middle roller (40). Alternatively, a hinge member (11) connects pivotally the front portion (45) and the middle portion (55) of the roller skate so that the pair of rear rollers (50) can be lifted up, thereby, allowing the skater to skate only with the front roller (30, 31) and the middle roller (40). In this way, the skater can gyrate smoothly at a radius smaller than that of a conventional roller skate.

Title: Enantiomer enrichment by membrane processes
Inventor: LINDER CHARLES
IPC: C07C51/42
Filed: 1989-06-07
Abstract: A continuous membrane adsorption/desorption or permeation process is provided which involves the enrichment/ separation of enantiomers from racemic mixtures. Suitable membranes used are of essentially chiral polymers, such as optionally chemically modified chiral polysaccharides or chiral acrylic polymers. The process is effected by the selective interaction between the chirality centers of the polymer membrane and the enantiomers, and further by transmembrane concentration and pressure differences. The process can be used for the treatment of any racemic mixtures and leads to high rates of enrichment/separation of the optical isomers. <IMAGE>

Title: System for separating speech from background noise
Inventor: HUNT MELVYN
IPC: G10L21/0208
Filed: 1989-12-06
Abstract: A digital signal processing system applies an adaptive filtering technique to sequences of energy estimates in each of two signal channels, one channel 1, 4, 6, 7, containing speech and environmental noise and the other channel 2, 5, 6, 7, containing primarily the same environmental noise. From the channel containing primarily environmental noise, a prediction is made of the energy of that noise in the channel containing both the speech and that noise, so that the noise can be extracted from the mixture of speech and noise. The result is that the speech will be more easily recognizable by either human listeners or speech recognition systems. <IMAGE>

Title: Focus detection
Inventor: PRIKRYL IVAN
IPC: G11B7/135
Filed: 1991-08-07
Abstract: An apparatus for evaluation of radiation beam geometry that finds application in determining the focus of an illuminating beam relative to an optical disk is disclosed herein. in one preferred embodiment, a light source generates a linearly polarized beam B which is collimated by a collimating lens 18. The collimated beam is then converged by an objective lens 24 onto the surface of the optical disk 14. The disk reflects the illuminating beam focused thereon back through the objective lens to a beam splitter 20. A portion of the optical energy incident on the beam splitter is then redirected to form a servo beam, wherein the degree of collimation of the servo beam is indicative of the focus position of the illuminating beam. A beam separation module 30, based on frustrated total reflection, having a reflectivity which varies in response to the angle of incidence of optical energy thereon is positioned to intercept the servo beam. The beam separation module is operative to separate the servo beam into transmitted T and reflected R beams of substantially similar shape and intensity. Electrical signals produced by photodetective elements 32, 34 in response to incidence of the transmitted and reflected beams thereon may then be used to generate a focus error signal. <IMAGE>
