Patent GB-2146724-A (GB)
Title: Torque-limited screw-thread locking fastener
Inventor: WILLIAMSON HERMAN L
IPC: F16B39/02
Filed: 1983-08-12
Abstract: A torque-limited screw-threaded locking fastener comprises an externally threaded shank (41) and an internally threaded collar (20). At least one convolution of the shank threads (43) is non-circular. The collar (20) has a nut section (25) connected by a shear section (35) to a drive section (21). The shear section (35) fractures when a predetermined torque is exerted between the two sections (21,25). The nut section (25) has an external rib(s) (33) engageable by a swaging tool (60) to radially inwardly displace the rib (33) so as to displace nut section material into the non-circular convolution (45) whereby to lock the nut (25) to the shank (41) after the drive section (21) is torqued off. The swaging of the rib to a lesser radial dimension does not change the torque level which was applied when the drive section (21) was torqued off. <IMAGE>

Title: Jitter circuits; assessing jitter performance
Inventor: WANT TREVOR LESLIE BARRY
IPC: H04L1/20
Filed: 1983-09-03
Abstract: The jitter circuits comprise a jitter generator and a jitter detector in which jitter signals are synchronously associated with transmitted or received data patterns. This permits the performance of data transmission systems to be assessed with particular regard to the way in which particular data patterns affect the systems tolerance to jitter. In Fig. 1, jitter information from a store 1 is used to impart jitter to a reference frequency which clocks data from a further store 6. The "jittered" data pattern is applied to a transmission system under test. <IMAGE>

Title: Improvements relating to the manufacture of porous articles
Inventor: PARRY RONALD
IPC: B29C67/24
Filed: 1984-04-19
Abstract: The present specification discloses a method of manufacturing porous articles for use in the garden, such as ornamental flower pots and shaped tiles. The method first requires dust free and lime-free stone chippings to be mixed with a resin so that the chippings each become coated with the resin. The coated chippings are then compacted in a suitably shaped mould, around an internal core if required, and the resin is allowed to cure at a constant temperature. The mould is subsequently opened to allow the finished article to be extracted. The irregular shapes of the chippings results in the finished article being porous due to the interstitial spaces unavoidably formed between adjacent chippings.

Title: Treatment of cementitious products
Inventor: ATKINSON ALAN WILLIAM
IPC: C04B41/50
Filed: 1984-12-15
Abstract: Shaped products (e.g. sheets) comprising a matrix of water-insolubilised organic polymeric material (e.g. a hydrolysed vinyl acetate polymer) filled with water-insoluble inorganic material (for example, a set hydraulic cement), as described for example in European Patent Publication 55 035 (ICI), have an unusually high flexural strength, above 40 MPa, but this falls considerably when the products remain in prolonged contact with water. By the invention, the extent to which flexural strength of such products is lost on contact with water is reduced by treatment with an aqueous solution of boric acid or a borate.

Title: Temperature indication
Inventor: LEVIN DANIEL
IPC: G01K11/06
Filed: 1987-09-04
Abstract: A temperature indicator (10) comprises a material which changes state at a predetermined temperature causing an indication which remains even if the temperature returns to its original value. A resettable indicator 10 includes containers 12, 14 and 16 in the upper ends 12A, 12B and 12C of which are located coloured frozen substances. When the temperature rises above one or more of the different freezing temperatures of the substances they melt and flow to the lower ends 12B, 14B and 16B. Those substances which have melted will then be visible at the lower ends even though the temperature may return below the freezing point. The indicator can be reset by melting all of the substances and freezing them at a common end before inverting the indicator to be ready for reuse. Another embodiment comprises an indicator giving an irrevocable indication that a temperature threshold has been exceeded. The indicator 20 comprises a substance 22 normally frozen, a membrane 23 perforated by external pressure or the freezing of the substance, a layer 24 of tissue paper or gelatine which retains the substance 22 when frozen but allows it to pass on melting, and a material 25 e.g. hydrous CoCl2 which changes appearance when contacted by the melted substance 22. <IMAGE>

Title: Signal processing circuit
Inventor: ARAMBEPOLA BERNARD
IPC: G06F17/15
Filed: 1988-02-09
Abstract: In order to correlate or convolute two complex valued sequences x(i), h(i) of samples using correlators or convolvers for use with real valued sequences, four such correlators or convolvers have been needed because the real and imaginary parts of each complex valued sequence have been each separately correlated or convolved with the real and imaginary parts of the other complex valued sequence. According to the invention, at least one such real correlator or convolver 17 has as one of its sequences the sum hR(i) + RI(i) or difference RR(i) - hI(i) of the real and imaginary parts of one of the complex valued sequences, and the amount of processing is thereby reduced. The whole operation may now be performed with three correlators or convolvers or a single correlator or convolver used three times in sequence. <IMAGE>
