Title: Manufacture of optical fibre preforms
Inventor: PILKINGTON CHRISTOPHER EDWARD
IPC: C03B37/012
Filed: 1989-11-29

Patent GB-2298538-A (GB)
Title: Dual Mode Radar System
Inventor: TAIT PETER D F
IPC: G01S13/72
Filed: 1990-02-28
Abstract: The system operates in low resolution tracking mode as well as a high resolution mode. In the low resolution mode, a region of space is repeatedly scanned with a transmitting beam of radar pulses using a plurality (A-D fig 4) of PRF's and a receiving beam to receive the radar returns. The returns are processed to obtain bearing range and radial velocity data for detected targets. After a target has been detected, on subsequent scans, higher resolution modulated pulses at one of the PRF's (fig 5) are transmitted in the vicinity of the target, and the range gating in store 19 only takes place in the region of the target range obtained from the lower resolution mode, and successive radar returns are motioned compensated using the radial velocity obtained during the lower resolution mode, before the returns are processed to obtain range and Doppler or radial velocity data. Processing demands are thus reduced and high resolution is available in real time.

Title: Cover for bladed rotor
Inventor: KIRKMAN BRIAN GEORGE
IPC: F04D27/00
Filed: 1990-05-12
Abstract: A cover 1 for covering a bladed rotor 3 during a testing operation has a face plate 10 of solid sheet like material having a centrally positioned orifice 11 through which air is drawn by the action of the parts of blades 4 adjacent to the orifice 11. The remaining parts of the blades 4 are in a stalled condition and therefore relatively unloaded. The power required to turn the rotor 3 is therefore reduced in comparison to that required if the cover 1 was not present which makes testing easier. The cover 1 also acts as a safety shroud preventing personnel coming into contact with the blades 4 as they rotate and containing the rotor 3 in the event of its disintegration.   <IMAGE>

Patent GB-2247792-A (GB)
Title: Sinewave generators
Inventor: PALMER KEITH JOHN
IPC: H03K4/02
Filed: 1990-08-31
Abstract: In a sinewave generator, the output of a square wave generator 30 at three times the desired frequency is frequency divided at 34 and at least one square wave signal at an odd integer multiple (greater than two) frequency is attenuated at 40 and subtracted at 18 from the divided signal before low pass filtering at 26, to produce the sine wave. By altering the division factor x of a counter/divider 32, a range of output frequencies is obtainable. By performing the harmonic generation in hardware, a considerable saving in processing time over systems using software control is achievable. Mark space ratios of unity of the waveforms applied to the subtractor 18 is assured by using divide by two circuits 36, 38 preceding the subtractor 18 or by use of specific logic circuitry with dividers 32, 34. The sinewave generator may be used as a tone generator with microprocessor circuitry. <IMAGE>

Title: Stator construction to permit increased heat transfer
Inventor: OVERTON BERNARD P
IPC: H02K1/27
Filed: 1990-10-05
Abstract: An electric motor is disclosed including heat spikes (36) within the stator slots (34). The heat spike (36) extend radially inward from the stator back iron into the slot (34) between the stator teeth (32). The heat spikes (35) placed within the stator slots reduce the heat path length and increases the heat transfer area to the iron. Together, these allow the winding heat to dissipate quicker and, at the same time, reduce the winding hot spot temperature and improve the motor's load rating. <IMAGE>

Title: Fraud control system
Inventor: VENN DAVID THOMAS
IPC: H04M1/673
Filed: 1990-11-06
Abstract: A method for detecting unauthorised access to a telephone system involves the transmission by a user of a security code on each occasion of access to the system. The code is incremented on successive occasions of access. The system memorises the sequence of codes ascribed to the user and subsequently displays this sequence so that unauthorised access to the network may be detected as a difference between the anticipated and ascribed sequences of codes. Preferably, the sequence of codes is displayed as part of an itemised call log which may, for example, be a customer's printed telephone bill. <IMAGE>
