Title: Flexible ducting
Inventor: WALTERS ALBERT EDWARD DAVID
IPC: F16L11/12
Filed: 1987-12-07
Abstract: Flexible ducting (11) formed by bending a length of plastics sheet into tubular form with overlapping edge portions (12, 13) bonded, as by adhesive, solvent or welding (14), to form a longitudinal seam (10) has a strengthening strip (15) of plastics material extending across the seam, with marginal portions (16, 17) bonded, as by adhesive, solvent or welding (18, 19) to the ducting (11) at both sides of the seam (10). Marginal welding (18, 19) preferably does not extend to the longitudinal edges (20, 21) of the strip (15), so that no bulging is caused if pressure is applied during welding, but preferably only slightly in from those edges so that they are not liable to be caught and torn by handling equipment. A strengthening strip may be similarly applied to a circumferential seam between two such lengths of flexible ducting. <IMAGE>

Title: Measuring devices
Inventor: BRADSTREET DEREK
IPC: G01B5/18
Filed: 1988-11-04
Abstract: A device for measuring the depth of irregularities or pits in the surface of a bore comprises a head 10 provided with an inflatable bladder 56 which when inflated engages a surface of the bore to displace the head laterally and bring a datum surface 60 at the opposite side of the head into contact with the bore surface 16.

Patent GB-2236292-A (GB)
Title: Boat towing arrangement
Inventor: MELVIN EDWARD
IPC: B63B21/56
Filed: 1989-09-15
Abstract: A device for attachment of a towing line (39) to a lifeboat (10) or the like is disclosed. It includes a swivel eye assembly (15) at the bow of the boat below the water dine (20). Secured to the swivel eye assembly is a normally lower end of a towing cable (17). The second end of the towing cable (7) is releasably secured to a bracket (21) above the water line. When connected to a towing line (39), the pull of the towing boat releases the upper end of the towing cable (17) from the mount above the water line. The towing force is then applied to the hull well below the water line, at a level which is more favourable from the standpoint of stability of the towed craft compared with the usual location of the towing line near the top of the fore end-of the towed boat. The invention presents a simple, inexpensive and safe way of attaching to the boat a towing line. The swivel eye assembly can be secured to the skeg of the boat. In boats which do not have a skeg, an eye bolt is secured to the hull of the boat to form the securement point for the swivel eye assembly. <IMAGE>

Title: Splicing paper webs
Inventor: BOWMAN KENNETH ALBERT
IPC: B65H19/12
Filed: 1990-04-12
Abstract: In an arrangement for splicing the start of a new roll of web-stock to the end of an old roll, both rolls are supported with their rotation axes horizontal on respective identical mobile reelstands or trollies which can be moved freely to and from the splicer, but which are accurately positioned (both mutually and with respect to the splicer) during splicing by a rail system associated with the splicer. As described, the top surfaces of a first pair of rails (37) (one each side of the trolley) are engaged by lateral projections (35) on the trolley, the said rail surfaces being configured to raise the trolley from at least some of its wheels as it is progressed towards the splicing station, whereby to ensure that the reel rotation axis is in correct horizontal alignment.

Filed: 1990-07-27
Abstract: Threaded tubular interference fit interconnections and related production techniques are disclosed that are for example useful with large diameter tubular members, including pipe bodies, that can for example function as casing for oil, gas, geothermal, disposal and other wells. In a preferred aspect of the invention there is root-to-crest and/or flank-to-flank interference between nose and inner portions (45, 64) of male and female threads (6, 14) of the disclosed interconnections, such as substantially to seal them against leakage at the maximum internal and/or external pressure rating of the pipe body, and a run-out portion (47) of the male thread and a corresponding portion (67) of the female thread (14) engage one another with interference to retain threaded engagement between said run-out and corresponding portions at the maximum axial force rating of the pipe body and also at the maximum internal and/or external pressure rating of the pipe body. These connections, when applied to API line pipe or other tubular products, can allow them to properly function as large diameter casing.

Title: Priority-oriented bus allotment system
Inventor: WERGEN GERHARD
IPC: G06F13/364
Filed: 1990-08-15
Abstract: A priority-oriented bus allotment system is designed with low circuitry expenditure for high flexibility and arbitration speed. For this, the lines a of the data bus D are initially fixedly associated with the individual bus participants N for the transmission of an instantaneous priority message P. In each participant N a check is made as to whether its own instantaneous bus access information-dependent priority P is of higher weight than that of all the simultaneously received priority messages P an from the other bus participants N. In this case, for the duration of the exchange of data blocks IB by way of the data bus D the issuance of priority messages P in all the participants N is blocked. Upon simultaneous presence of equally high variable (software) priority in several participants N a circuitrywise predetermined participant priority PK decides the bus access between these participants N. <IMAGE>

Title: Compound helicopters
Inventor: BALMFORD DAVID ERNEST HALL
IPC: B64C27/26
Filed: 1990-12-05
Abstract: A compound helicopter having a lift rotor assembly (13) for providing lift in vertical take-off/landing, hover and slow speed flight and a fixed wing (15) for providing lift in high speed forward flight, has its operating efficiency improved by a combination of features. Air is blown through slots (24, 25) in a tail boom structure to control circulation of lift rotor downwash air whereby a lateral force is obtained on the tail boom (12) for counteracting the effect of lift rotor torque. Air is selectively vented from air outlet ports (27) provided at either side of the tail boom (12) to provide lateral forces for yaw control. In high speed flight yaw control is obtained from a fin (31) and rudder (32) mounted on the tail boom. An engine driven fan (20), which may be an engine by-pass fan, provides low pressure ratio air to the interior of the tail boom structure during vertical take-off/landing, hover and slow speed flight, and provides higher pressure ratio air for propulsion in high speed forward flight. The higher pressure ratio air may be vented from the aft end (29) of the tail boom structure and may be mixed with engine exhaust gases. in an embodiment of the invention (Figures 5 and 6) gas turbine engines (51) having engine by-pass fans (53) are mounted on the fixed wing (15) and in high speed forward flight higher pressure ratio air is delivered rearwardly of the engines for propulsion, <IMAGE>

Title: Optical multiplexing
Inventor: TAYLOR ROBERT MYLES
IPC: H01S3/10
Filed: 1991-03-27
Abstract: An optical multiplexing system has a source 1, 3 of depolarized radiation at one end of a non-birefringent optical fibre 4 that extends to a decoding interferometer 5. Sensors 11 to 13 in series (or parallel) along the fibre induce birefringence so that the radiation is superimposed onto two polarization modes producing two output wave trains from each sensor with different time separations. The interferometer 5 measures the time separations of the wave trains to identify the sensor and its output. The sensors may be accelerometers, switches or lengths of fibre which are subjected to twist or lateral pressure. <IMAGE>
