Title: Mooring jib for use in loading an oil tanker - from an offshore prodn. platform
IPC: B63B22/02
Filed: 1973-05-21
Abstract: System for loading a ship with a fluid from an off-shore platform, partic. an articulated platform, comprises (a) a rigid elongated arm or jib articulated at one end to the platform above the surface of the water in such a way as to permit motion at least around a horizontal axis, while having at its other end a mechanism for connection to a mooring block fixed to the ship. (b) a rigid pipe supported along its whole length on the jib, connected at one end to a pipe fixed to the platform and at the other end to a flexible pipe having a coupling device at its free end for connecting it to a second fixed pipe on the ship. Avoids the adverse effects of waves on the flexible pipe where the free end of this is supported on a float and is picked up by the tanker for loading purposes, and eliminates the need for a slave mooring construction for the ship.

Title: Run roll for vehicle testing - with method of manufacture of run rolls for vehicle testing stands
IPC: G01M17/007
Filed: 1973-12-27

Patent FR-2230624-A1 (FR)
IPC: C07C31/02
Filed: 1974-03-01
Abstract: Isocyanates are produced in high yield by non-catalytic short contact time pyrolysis of the corresponding urethane at temperatures in the range of 350 DEG - 550 DEG C under conditions of controlled residence time and pressure, followed by two-stage condensation of the dissociation product vapors. The first stage is the rapid cooling of the product vapors to condense out the isocyanate product. The second stage effects cooling to the lower temperatures required to condense out the alcohol product of dissociation. Isocyanate yields in excess of 95 percent can be obtained by the thermal pyrolysis.

Title: Scintillation camera with plane regular scintillation crystal - has photomultipliers and computing circuits to provide spatially dependent output
IPC: A61B6/00
Filed: 1974-09-06
Abstract: The scintillation crystal reacts to radiation in a spatially limited zone corresponding to the place of generation by the generation of light flashes. Some photomultipliers have their optical axes at right angles to the plane of the scintillation crystal and have photocathodes to absorb the light emitted by the crystal. Computing circuits connected to the photomultipliers are used to determine the projection of a light flash in the crystal on a reference axis in the plane of the crystal. The circuits work together with aids to obtain an analytical function at the outputs of the photo-multipliers, which is dependent on the place of the light flash in the crystal.

Title: Multi-layer welding rods in alloys difficult to draw - made from composite clad strip
IPC: B23K35/02
Filed: 1974-11-15
Abstract: Electrode mfr. using different metal or alloys, starting from clad strip or a similar material which is formed into a roll and then drawn to the dia. of the welding rod required. Alternatively, the clad metal can be formed into a roll and filled with metal powders when the latter materials are difficult to draw; welding powders can also be included in the hollow core, after which the filled roll is drawn to size. Welding rods can also be made by winding a spiral of narrow clad-metal strip round a wire core, e.g. forming a 'thread' of different metals or alloys round the core. This process overcomes the difficulties which arise in attempting to draw welding wire in alloys very difficult to work (e.g. aluminium-bronzes) and where the low electric conductivity of the electrode causes problems in welding.
