Title: Introducing additive into a closed container
Inventor: GROVES MICHAEL HOWARD
IPC: B65D81/32
Filed: 1987-02-12
Abstract: A system for introducing a flowable additive (3) from a capsule (1) to paint (4), varnish, woodstain or the like in a closed (preferably lidded) container (2)(for example a paint container) modified by the provision of a relatively easily openable inlet (9) into the container. Preferably the inlet is located in a lid (6). The Capsule comprises a chamber (23) which defines a volume which contains the additive. The system is provided with means (25 and 34) for creating an opening in the chamber which can communicate with the inlet and means (preferably a compressible chamber) for positively expelling additive through the opening by contracting the volume which contains the additive. The capsule and container are also provided with co-operable locating means (10 and 30 with 25) which can co-operate to assist in locating the opening created in the chamber in communication with the inlet. Also a capsule and a closed container for use in the system and a method of introducing additive using the system. Use of the system reduces the risk of spillage and splashing and permits more controlled tinting of paint and therefore is more suitable for use by inexperienced people.

Title: Ion beam source
Inventor: EVANS ANTHONY CYRIL
IPC: H01J27/16
Filed: 1989-06-01
Abstract: An ion beam source comprises an RF excited plasma with means to extract the ions from the envelope of the plasma, the RF energy being applied capacitatively to the plasma. The extraction can be by means of extraction electrodes or by magnetic fields or both and the capacitor for applying the RF energy may have plates spaced along or transverse to the direction of the beam. As shown in Fig. 1, two semi-cylindrical capacitor plates 1, 2 are mounted externally either side of a silica tube plasma chamber, ions being extracted by virtue of the field between electrodes 3, 4. Alternatively, as in Fig. 3, the RF is applied to alternate spaced bands 2 and the plasma may be enhanced by a magnetic field formed by sets of magnets, neighbouring sets having the opposite polarity. <IMAGE>

Patent GB-2240867-A (GB)
Title: Speech analysis
Inventor: HOLMES JOHN NICHOLAS
IPC: G10L11/00
Filed: 1990-02-08
Abstract: In automatic speech recognition it is usual to make a spectral analysis of the incoming speech signal and it can be useful to detect the frequencies and intensities of the formants. However although the formants are mostly quite well defined during vowel sounds there are frequent occasions when this is not so and it is not so during a high proportion of consonant sounds. The present invention determines the frequencies at which the centroids of respective frequency versus power distributions occur in a plurality of frequency bands of a signal representing speech (approximately corresponding to the ranges of individual formants). The centroids have most of the desirable properties of formants but also carry significant information for those sounds for which the conventional definition of formants does not seem appropriate. Preferably the powers in the bands in which the centroids are measured are also determined. The incoming signal is filtered (2) into separate frequency bands and the power in each band is measured (4). The output signal in each band is weighted by 3 dB per octave (5) and then the power in that band is measured (6). The power ratio obtained (7) for a band from the power after 3 dB weighting divided by the power before weighting gives an indication of the position of the centroid of that band in the frequency spectrum. <IMAGE>
Patent GB-2243010-A (GB)
Title: Fluidic pressure loss warning system
Inventor: BADER STANLEIGH
IPC: B60C23/04
Filed: 1990-04-10
Abstract: The system comprises a detector/transmitter(s) 1 and a receiver 2. The detector/transmitter(s) comprises a spring loaded switch which remains in a closed (off) position until the pressure which it's in contact with decreases below a pre-set threshold, allowing switch to assume an "on" position, causing a coded signal to be emitted either electro-magnetically or sonically to the receiver which, in a vehicle-based situation, would be mounted within view of the driver, presenting a visual and/or audible warning of air pressure loss at the pneumatic wherein or whereon the detector/transmitter(s) is sited. In its simplest application, the detector/transmitter(s) in a vehicle-based situation would be mounted on each tyre valve, the tyre air pressure keeping the detector/transmitter spring loaded switch in "off" position until there's a critical pressure loss, activating the system aided by the integral battery and transmitting a pre-set coded signal. <IMAGE>

Abstract: The tooth flanks of a hardened gearwheel (W) are fine machined by a tool resembling a gearwheel, whose tooth flanks have an abrasive surface and which rotates in meshing engagement with the workpiece. In order to avoid instances of damage to the tool, resulting from residual burrs and the like, in the toothing of the workpiece, a double tool is used, similarly toothed tool elements (T1, T2) which are axially spaced-apart and which come into use one after the other. In this method, firstly the residual burrs and the like are removed by the first tool element (T1), and subsequently the actual fine-machining is performed with the second tool element (T2). The second tool element (T2) is rigidly mounted on a hub or like carrying member whereas the first tool element (T1) is mounted on the hub in radially yielding manner. <IMAGE>

Title: RF applicator for magnetic resonance imaging
Inventor: EHNHOLM GOSTA JAKOB
IPC: G01R33/62
Filed: 1991-04-04
Abstract: An applicator for coupling an rf field to or from a sample during magnetic resonance imaging comprises an electrical periodic structure which oscillates with substantially the same phase over its whole length at its operating frequency (NMR or ESR). The simplified version shown has two sections 2, 3 twisted relative to each other by 90 DEG  to give a helical field pattern and connected to quadrature oscillators to give a rotating field. The latter effect may also be obtained using pairs of coils tuned to slightly different frequencies. The field may be focussed to reduce external noise. The arrangement is particularly useful in apparatus employing dynamic polarisation, i.e. for exciting ESR coupled to NMR spins (Overhauser effect) to enhance the NMR signal (ESREMRI). <IMAGE>
