Title: Optical amplifier or image intensifier - minimises distortion due to pump heating using shaped amplifier surface with contour changing with increasing temp
IPC: H01S3/23
Filed: 1974-11-22
Abstract: Optical amplifier is intended to provide a minimum distortion effect arising from the light pump. The amplifier element receiving the output from the light pump is shaped to concave surface (11), and this concave surface is arranged facing the pump, the curvature becoming modified as a result of heating due to the pump output, such that it presents during some interval of time a plane mirror surface for the light amplifier. The incident surface for the amplifier, also shaped, has a surface layer (13) which is transparent to the amplifier light and is reflecting to the pump light. A further filter (14) may be placed between the concave surface and the pump source.

Title: Gas meter with built in error correcting system using digital counters - multiplies pulses by factor taking account of Reynolds number temperature pressure
IPC: G01F15/04
Filed: 1975-04-17

Title: Electronic control for tariff instruments - utilises two clock controlled preprogrammed binary counters to change pulse rate
IPC: G01R21/133
Filed: 1975-08-26
Abstract: An electronic regulator is used in tariff instruments such as maximum indicator counters and totalisors. An electronic regulator is able to operate without wear and without requiring maintenance. An electronic regulator uses two clock controlled binary counters (4, 5) to change the pulse rate.

Title: Submersible columns for supporting platforms above water level - which rest on ball connectors to allow racking but maintain vertical alignment
Inventor: MICHEL DOMINIQUE
IPC: B63B35/44
Filed: 1976-07-23
Abstract: The structure capable of rocking is submerged into deep water. The column shaped structure rests on a ball connector on a heavy base and the column top carried a platform above water level. The centre line of the column remains vertical although the column may follow rocking movements caused by ocean currents. The pivoted joint at the bottom of the column is formed of two hemispherical seats. The column is loaded with ballast near its base. The whole weight of the arrangement consisting of ballast, column and platform is greater than the maximum buoyancy force acting on the column in case of maximum swell. The ball joint is at all times subjected to the compression. The contacting elements of the pivoted connection are made of cast, non-machined metal. The contacting surfaces are ground in situ. and a flushing liquid together with the abraded metal particles is injected into the two components in contact. The process is carried out due to the metal to metal contact.

Title: Crane for transferring cargo from ship to shore - has computer controlled auxiliary drum to maintain cable tension despite rough sea (NO 20.11.78)
Inventor: HAVARD JEAN FRANCOIS
IPC: B66D1/52
Filed: 1977-04-26
Abstract: The transfer of cargo from ship to shore by a crane is difficult during a heavy swell which causes the ship to rise and fall. This is solved by fitting the crane (1) with an auxiliary winding drum (4) which receives one end of the main lifting cable (9). The other end of this cable is wound on the main drum (3). A computer measures the tension in the cable (9) and controls the auxiliary drum so that this tension equals the weight of the lifting hook and pulley block (12). As soon as this tension is exceeded the auxiliary drum is braked and the main winding drum is set in motion to lift the load (10).
