Patent GB-2325778-A (GB)
Title: Device for extracting energy using radiation pressure of virtual particles
Inventor: HUGHES JOHN
IPC: F03G7/00
Filed: 1997-05-29
Abstract: The device utilizes the Casimir effect whereby two flat parallel conducting plates are pushed together by a small force because of the pressure of virtual photons. The pressure arises because the photons between the plates with a wavelength longer than the gap between the plates are shorted out and thus the pressure in the cavity is less than that outside. As the plates move parallelly together they do useful work. One plate is fixed to an axis and the other is rotated away horizontally, no energy input being required, is pushed up and away from the first plate, and continues to rotate until the plates overlap again. Two plates may be secured to the axis so that a double action is obtained in each cycle of the rotating plate.
Patent GB-2325898-A (GB)
Title: Retractor
Inventor: MCCULLOCH JIM
IPC: B60R22/44
Filed: 1997-06-04
Abstract: A safety restraint seat belt retractor comprising a spool (8) about which seat belt webbing is wound. The spool (8) is tensioned in the webbing rewind direction by a coil spring (3) mounted between the spool (8) and the retractor housing (1). The spring (3) is arranged such that when the webbing is fully rewound, the spring abuts the spool shaft (8) only over a portion of the circumference thereof. Thus only a small amount of tension is applied when the webbing is unwound, which provides a larger zone of comfort for the occupant. In another aspect of the invention, a simple and secure fastening for the end of the spring (3) is provided, whereby the end passes through a diametric gag in the spool shaft. The two sections (8a, 8b) of the shaft are offset, and the end (7) of the spring (3) is bent at each end of the gap away from the extending diametric surfaces.

Title: Apparatus and methods for creating and using portable fonts
Inventor: COLLINS JOHN S
IPC: G06F40/143
Filed: 1997-06-10
Abstract: A computer system can translate original font descriptions, often from text contained on one computer, into new font descriptions which use different outline segmentation, and then install the new font descriptions into a computer operating system, often on a second computer, so operating system calls can be used to render the text. The system can send a first message over a network to request a text, and a second message to request a set of font descriptions for rendering the text. Preferably the text includes an identifier which can be used in the second message to identify the particular font descriptions desired. The system can receive a body of text and an old set of font resources and can derive a customized new set of font resource from the old set based on the particular character-font shapes in the text, eliminating multiple font descriptions for the same character-font shape and font descriptions for character-font shapes which do no currently occur in the text. The system can also render the character font shapes of a text from a plurality of portable font resources, each of which can have different characters from the same fonts, Such systems can receive and cache separate portable font resources.
Patent GB-2320295-A (GB)
Title: Injecting cooling air into stator vane wake
Inventor: GLEZER BORIS
IPC: F01D11/00
Filed: 1997-07-09
Abstract: For restricting the ingress of hot combustion gases into a turbine disc plenum 60 of a gas turbine engine, as the hot gases flow from turbine nozzle vanes 39 into the turbine blades 43, a jet of engine cooling air is injected via upwardly and tangentially inclined passages 52 in an inner shroud 36 into a wake region (75)(fig.5) immediately behind and downstream of the vanes 39, thereby reducing the static pressure recovery otherwise occurring within the wake region. Thus, a lessor amount of buffering air is required within the turbine disc plenum to prevent the ingress of hot gases thereby resulting in an increased efficiency of the engine's cooling air delivery system and over all engine performance. The cooling air is tapped from the engine's compressor via a discharge plenum.

Title: Semiconductor device and digital delay circuit
Inventor: KAWASAKI KENICHI
IPC: H03K5/13
Filed: 1997-07-17
Abstract: In a semiconductor device for maintaining the timing of an output signal at a constant phase difference relative to an external clock signal, independent of differences in characteristic, changes in temperature and/or fluctuations in supply voltage, an input circuit 13 receives a clock signal from an external clock 11 and outputs a reference signal, an output circuit 14 receives an output timing signal and outputs an output signal according to the timing of the output timing signal and an output timing control circuit 20 controls the output timing so that the output signal exhibits a given phase relative to the signal from the external clock 11. The output timing control circuit 20 includes a delay circuit 21, a phase comparison circuit 22 and a delay control circuit 23 for specifying the magnitude of a delay to be produced by the delay circuit 21. A dummy input circuit 24 produces a delay of the same magnitude as that of the input circuit 13, and receives as input the output timing signal from the delay circuit 21 and supplies an output to the phase comparison circuit 22. Further aspects relate to inputting or outputting data synchronously (Figs 3 and 82), a digital delay circuit and a digital delay circuit including a shift register (fig 41). Embodiments of timing control circuits are described (Figs 10, 29, 34, 40, 48, 49, 54, 56, 57, 65, 86, 88, and 90). The delay control 23 may use an up/down counter (526, Fig 41 and 531, Fig 54). The timing control circuits may be used with synchronous semiconductor memory circuits.

Title: Ion source for a mass analyser and method of cleaning an ion source
Inventor: BAJIC STEVAN
IPC: H01J49/04
Filed: 1997-08-06
Abstract: An ion source for a low pressure mass spectrometer has an atmospheric pressure sample ioniser operative at relatively higher pressure to provide a sample flow containing desired sample ions to the mass spectrometer via an inlet orifice 38. The sample flow invariably contains involatile components that are infused either as chromatographic buffers or which appear in the analyte as sample extraction byproducts. As the sample ions pass from the high pressure to the low pressure regions 36 through the orifice 38, these involatile components are deposited on the peripheral regions of the inlet orifice. The invention provides a conduit 48 for the transportation of a cleaning fluid which has an opening 50 adjacent to the inlet orifice for dispensing the cleaning fluid onto at least a portion of a surface of the orifice member during operation of the ion source.

Title: Self tuning and compensating turn fault detector
Inventor: PREMERLANI WILLIAM JAMES
IPC: G01R31/06
Filed: 1997-03-26
Abstract: A method for detecting turn faults in an induction motor includes obtaining motor current and voltage waveforms and converting the motor current and voltage waveforms to digitized current and voltage waveforms. Fundamental phasors of the digitized current and voltage waveforms are extracted and, a symmetrical component transform is applied to the fundamental phasors to obtain symmetrical component current and voltage phasors including a negative sequence voltage phasor (V_) and negative sequence current phasor (I_). A fault injected negative sequence current (Ii_) is estimated according to the following equation Ii_ = I_ - V_/Z_ - Ir, wherein Z_ is a characteristic negative sequence impedance and Ir is a residual injected negative sequence current. The existence of a turn fault is determined by comparing the estimated fault injected negative sequence current with a threshold fault injected negative sequence current.

Title: Embedding digital watermarks in compressed image data
Inventor: YAMADAJI SHINJI
IPC: H04N1/32
Filed: 1998-05-08
Abstract: A digital watermark, which may be generated by scanning, 101, and held in a memory, 105, or may be held in an external memory 103 is inserted into a block transformed image signal in a processor, 102 (Figure 5). The image signal, which may also originate from the scanner, is divided into blocks and then undergoes DCT, quantisation and scanning to 1-D format. The digital watermark, which is also coded, is inserted into a zero-run section immediately preceding and End Of Block in each of the quantised, scanned blocks of image data. Thus, the digital watermark occupies positions in the coded signal which would otherwise be occupied by high frequency image data and appears in the reproduced image as high frequency noise and maynot be significantly perceptible. An authorised decoder removes the digital watermark data from the coded image signal and replaces it by zeroes, thus returning the image signal exactly to its original, unmarked, form.
