Patent GB-2285453-A (GB)
Title: Sintered articles
Inventor: PURNELL CHARLES GRANT
IPC: B22F5/12
Filed: 1993-09-21
Abstract: Digital data are encoded using an electromagnetic interference suppression method and apparatus. In the invention, nonreturn-to-zero signals (52) are input along with pseudorandom code signals (70) into a flip-flop circuit (53). The two output signals from the flip-flop circuit (53) are fed into a pair of AND gates (54, 55), which, in turn, produce output signals which are fed into a driver circuit (56). The driver circuit (56) produces a randomized MTL-3 signal (71) as its output. <IMAGE>

Title: Cryogenic vacuum pump with electronically controlled regeneration
Inventor: BARTLETT ALLEN J
IPC: F04B37/08
Filed: 1994-02-23
Abstract: In a fast partial regeneration process, the second stage of a cryopump is heated as purge gas is applied to the cyropump. In a test loop, the purge gas is turned off and the roughing valve is opened. If the cyropump is judged to be sufficiently empty of gases from the second stage by being roughed to a sufficiently low pressure in a short period of time the system proceeds to a reconditioning phase. If the system fails the test, however, it is repurged with a burst of warm purge gas and then retested. After passing the emptiness test, the pressure is further reduced by the roughing pump as heat is applied to the second stage. The heat is then turned off for cool down as the system continues to be rough pumped to a base pressure. At about the base pressure, the roughing valve is cycled to maintain the cryopump pressure at a level near to the base pressure. Where multiple cryopumps are coupled to a common roughing pump manifold, they are processed through a partial regeneration sequence in lock step to avoid cross contamination. <IMAGE>

Title: Terminating optic fibre bundle by compressing deformable ferrule
Inventor: TOMS CHRISTOPHER DAVID
IPC: G02B6/36
Filed: 1996-01-31
Abstract: A fibre optic bundle end is produced by placing the end in a deformable ferrule 6. The ferrule 6 and the fibres therein may be heated and whilst still in the furnace (22 Fig 6) are radially compressed by compression members 2,4 so that the fibres become lightly packed, after which the protruding fibre ends may be cut off and the cut surface polished. The compression is achieved by rotating the ferrule 6 and fibres back and forth about the bundle axis whilst the compression members which are bars passed through the furnace move together radially of the ferrule 6, the said members being mounted for reciprocation so as to allow the ferrule 6 to roll thereon as it rotates. The ferrule 6 is preferably stepped at 6A.

Title: Oil pump sprocket cover for i.c. engine
Inventor: OZEKI HISASHI
IPC: F02B67/06
Filed: 1996-07-03
Abstract: One side of an oil pump sprocket cover 34 is fixed to the crankcase and the other side of the cover 34 is fixed to the oil pump 20. The cover 34 thus assists in supporting the pump which reduces the number of bolts needed to attach the pump to a crankcase, and thereby achieves a reduction in weight, assembling manpower, and cost. The cover 34 may be attached to the oil pump 20 by a bracket 78 which receives oil flowing through a clearance 66 and allows the oil to flow down into the sump after aeration of the oil has decreased. The clearance between the sprocket cover 34 and the driving chain 32 may be greater (clearance S2, fig.15) where the chain 32 leaves the cover 34 than where it enters (clearance S1) to reduce the velocity of the oil, and hence the oil mist and aeration, where the chain 32 leaves the cover 32.

Title: Preventing discontinuities in electronically-interlocked parallel-multiplexed control system
Inventor: ATSUSHI MUKAI
IPC: B61L19/06
Filed: 1997-01-14
Abstract: An electronically-interlocked parallel-duplexed control system includes an inservice system l and a standby system 2. Both systems are operated constantly in a parallel duplexed manner and interlocked electronically so that upon occurrence of a fault in the in-service system, the standby system is put into operation to serve as the in-service system by change-over unit 3. The system is imparted with facility for ensuring continuity in the output control data to be supplied to a device under control 6 upon changing-over of the standby system to the service operation mode. The inservice system l transfers output control data and a CRC (cyclic redundancy code) value calculated on the basis of that data to the standby system 2 by way of mirror memories 7a, 7b serving as interface. The standby system compares the received CRC value with one calculated on the basis of output control data in the standby system. When the comparison results in discrepancy, a fault signal is generated for preventing unit 3 from changing over the in-service system to the standby system even when abnormality occurs in the in-service system. The control output may thus be prevented from becoming discontinuous.
