Title: Electrical switchgear
IPC: H01H33/18
Filed: 1981-10-09
Abstract: The flow of load current to a T- off circuit 12 of ring main equipment is controlled by a contact set CS3 including a pivotable contact arm 35 and a fixed contact 34. When the contacts 34 and 35 disengage to draw an arc therebetween, a field coil 37 surrounding an arcing electrode 36 is brought into circuit by transfer of the arc root from the contact 34 to the electrode 36 and generates a magnetic field which causes the arc to rotate and become extinguished. Such extinction is assisted by sulphur hexafluoride gas contained in a housing 13 within which the contact set CS3 is disposed. A contact assembly 41 is also disposed within the insulating environment of the housing 13, and includes a contact 44 which can be pivoted to earth the contact arm 35 when the contact set CS3 is open. Also contained within the housing 13 are further contact sets CS1 and CS2 which control the flow of current through respective ring main cables 10 and 11. <IMAGE>

Title: Producing textile or non-textile yarn structures
IPC: D04B39/00
Filed: 1981-10-23
Abstract: In the method, two individual yarns 3 and 4 are continuously interlinked with one another, on the principle of forming a seam on a sewing machine, using two tubular yarn-guiding interlinking instruments 1 and 2 and a pointed supporting plate 6. Each of the instruments 1, 2 has a rectilinear shank portion via which the instrument is connected to a moving part. The shank portion merges into a yarn guiding portion which is bent in the shape of an arc of a circle and which is slotted on the convex side to form a yarn passage aperture 1'. The moving parts serve successively to impart an oscillatory motion to the interlinking instruments 1, 2, the paths of motion of the instruments intersecting one another. The plate 6 is held at one end and converges to a point at the other end. It serves to support the yarn structure 7 on its pointed end portion and is mounted in the zone of intersection of the paths of motion of the interlinking instruments 1, 2. The method may be used to produce a yarn structure comprising only one individual yarn interlinked similarly to a chain stitch on a sewing machine. <IMAGE>

Title: Phase modulator
Inventor: CHUA LYE-WHATT
IPC: H03C7/02
Filed: 1981-11-13
Abstract: A phase modulator in a compact, generally planar form and suitable for fast phase-shift keying comprises a slot transmission line series T (3) having three branches of which one (4) forms one port of the modulator and of which the other two (5, 6) are in series with one another and are coupled by symmetrical microstrip lines (12, 13) to a common line (17) forming another port of the modulator. Two diodes (23, 24) respectively bridge the two series arms (5, 6) at the junction of the branches and are connected in opposite senses to a common terminal (21) to which a modulating signal can be applied so as substantially to short-circuit either one of the branches (5, 6) while leaving the other branch unaffected. Since signals in the two branches (5, 6) are in antiphase, modulation between phases differing by 180 DEG independent of frequency can be obtained; frequency- independent impedance matching at the two ports can also be obtained.   <IMAGE>

Title: Flash synchronising circuit
IPC: H05B41/30
Filed: 1982-03-02
Abstract: A flash synchronising circuit synchronises the flash discharge from a flash discharge tube 15, whereby an article subjected to cyclic phenomena, such as cyclic fatigue loading, is stroboscopically illuminated at any time instant during each cycle of the phenomena. A cyclic fatigue loading machine (11) supplies as an input to the synchronising circuit a ramp-shaped sync. signal which the circuit level-shifts prior to application to a comparator. When the comparator senses that the level on the ramp sync. signal is equal to a reference voltage a transistor (MPS 6515) is turned on to turn on an SCR (IR 1220) causing a 0.022MF capacitor to be discharged through the primary of a pulse transformer 23 having a secondary connected to a trigger electrode 25 of Xeron flash tube 21. The phase of the flash with respect to the sync. signal is varied by adjusting the reference voltage input to the comparator. <IMAGE>

Title: Improvements in anti-skid braking systems for vehicles
Inventor: FARR GLYN PHILLIP REGINALD
IPC: B60T8/42
Filed: 1982-03-19
Abstract: An anti-skid braking system for a vehicle incorporates a modulator (2) for modulating a supply (16) of operating fluid to produce a supply of brake-applying fluid (17) under pressure to apply the brake (67), and a flywheel mechanism (7) for emitting a skid signal to control operation of the modulator (2) in accordance with the deceleration of the braked wheel. The flywheel mechanism (7) incorporates a flywheel (50) which is so mounted for rotation relative to the braked wheel that relative rotation therebetween causes the skid signal to be emitted. A hydraulic pump (39) driven by rotation of the braked wheel only where there is a skid signal, is operative to control the increase in the pressure of the brake-applying fluid such that, irrespective of the status of the skid signal, the pressure of the brake-applying fluid can only be increased following a skid, if the wheel is rotating. <IMAGE>

Title: Noise Compensating Spectral Distance Processor
Inventor: BRIDLE JOHN SCOTT
IPC: G10L15/20
Filed: 1982-11-19
Abstract: A spectral distance processor for preparing an input speech spectrum and a template spectrum for comparison, as for example in pattern matching by spectral distance computation, has means for masking the input spectrum (x(f)) with an input noise spectrum estimate (m(f)), means for masking the template spectrum (y(f)) with a template noise spectrum estimate (n(f)) to give masked spectra (x(f), y(f)), and means for marking samples of each masked spectrum with a noise mark (MI, MT), for example 1(speech) or 0(noise), dependent upon whether the sample is estimated to be due to speech or noise. Such noise marked spectra may then be used in spectral distance pattern recognition algorithms. The noise mark may be used to adjust normalisation applied to the spectra before comparison or to recognize that a spectral distance may be due to noise by substituting a default distance for the actual distance should the greater of the masked spectrum samples be marked as noise. <IMAGE>
