Title: System and method for synchronization of rotary head magnetic recording/reproducing devices
Inventor: HANDLEY KIRK H
IPC: G11B27/13
Filed: 1984-04-03
Abstract: A timing error between consecutive tracks of reproduced data from a rotary scan recording/reproducing device is detected as a difference between a normal and actual occurrence of a synchronization signal. A correction signal is provided to reduce the timing error and it is stored, updated and utilized to offset a bit counter synchronous with the reproduced data in the absence of the synchronization signal. The effect of short term dynamic errors is reduced by accumulating occurrences of the timing error in the same direction and updating the stored correction signal only when a predetermined number of occurrences in one direction is obtained.

Patent GB-2176274-A (GB)
Title: Combustor for gas turbine engine
Inventor: CANNON MICHAEL FRANCIS
IPC: F23R3/06
Filed: 1985-06-20
Abstract: The combustor employs an array of fuel injectors arranged in the mouth plane of the combustor flame tube. Each injector has a baffle plate 44 through which the injector nozzle projects, the baffle plate having axial holes 49 for atomisation air to intercept and atomise radial fuel jets from the injector nozzle. Cooling of the flame tube is performed by full coverage impingement and effusion without disturbing the cooling film by entry and penetration of transverse air jets. Flame stabilisation is achieved under all required operating conditions by the radial-fuel/axial-air atomisation in conjunction with the baffle plates. Comprehensive combustion mixing and dilution is achieved by the uniformly distributed supply of up to 90% of the total air supplied to the combustor around and through the baffle plates. There is a resultant economy in the air used for cooling, a uniformity of temperature distribution, stability of operation, and minimal emission of oxides of nitrogen. <IMAGE>

Patent GB-2163493-A (GB)
Title: Radial piston device
Inventor: BUDECKER LUDWIG
IPC: F04B1/107
Filed: 1985-08-07
Abstract: A radial piston device (especially a pump) has pistons (25) slidably guided directly in respective cylinder bores (14) of a rotary cylinder body (7), the pistons carrying balls (15) for co-operating with the inner surface of an eccentrically mounted cam ring (8). The cylinder body (7) is rotatable around a pintle (20) provided with inflow and outflow passages (21, 22). The cam ring (8) is rotatably mounted on the casing (1) via roll bodies (30). If due to high friction in the cylinder bore (14) the balls (15) tend to slide on the cam ring (8) instead of rolling, the cam ring (8) can rotate. Thus sliding of the balls (15) on the running surface of the cam ring (8), which is unfavourable with regard to efficiency, is prevented by the rotation of the cam ring (8). <IMAGE>

Patent GB-2180381-A (GB)
Title: Communication systems for use with AC power lines
Inventor: WHITE ALFRED KENNETH
IPC: H02J13/00
Filed: 1986-08-18
Abstract: Electronic switches (7) are switched on and off in response to coded signals generated by a transmitter (5) which feeds the signals to AC power lines (1,2,3 and 4) of a three-phase power supply. The signal intended for any one electronic switch is fed only to the power line associated with that switch and starts with a phase identifier characteristic of that particular power line. Signals fed to the power lines are received by receivers (6) which are individually associated with the power lines and control associated electronic switches. Each receiver can respond only to a signal starting with the associated phase identifier. This avoids errors from echoes or vestiges of signals that tend to occur on the other power lines. Each of the receivers associated with any one of the power lines has a different address, and responds only to a signal including its own address. Each signal also includes an instruction which causes the addressed receiver to operate the associated electronic switch in a predetermined manner. A supervisor is described for programming the transmitter. <IMAGE>

Title: Determining alignment in optical fibre fusion splicing
Inventor: LOU LOUIS PETER
IPC: G02B6/38
Filed: 1987-04-02
Abstract: A method of determining when the end faces of two optical fibres 1, 11 abut comprises arranging the two optical fibres in approximately axial alignment and with their end faces 4, 14 spaced apart, causing one of the fibres 1 to oscillate transversely of its axis with respect to the other 11 and causing it to move in a direction towards the other optical fibre, and monitoring the approaching optical fibres to determine the position at which there is substantially no relative transverse movement between the two optical fibres, at which position their end faces will be abutting. Preferably, light is injected into the core of one of the optical fibres 1 and the intensity of light which is transferred into the core of the other optical fibre 11 and which oscillates between maximum and minimum values due to the relative transverse movement is monitored to determine the position at which the intensity of the transferred light is constant, thereby indicating that there is no relative transverse movement between the two optical fibres and that their end faces are abutting. <IMAGE>
