Title: Tank for transporting liquified petroleum gas for ships holds - has thin walls of formed plates supported by surrounding structure
Inventor: LOPEZ JOSE DEUS
IPC: F17C3/02
Filed: 1976-01-02
Abstract: The tank is constructed from thin metal sheets, rectangular or any other geometic shape, their edges joined together by welding. The sheets are made from alloy steels containing nickel and chromium, or from special aluminium alloys, to withstand the cryogenic temperatures involved. Each plate has, formed into its surface, a number of concentric annular rings arranged about the geometric centre of the sheet. These rings have a rounded profile and are produced by standard sheet metal working techniques; their function is to absorb mechanical stresses and provide stiffening. Each sheet is anchored at its geometric centre to the surrounding structure.

Title: Controller for movement of drilling rig shaft train - enabling advance to be reduced in more difficult ground
IPC: E21B19/09
Filed: 1976-06-11
Abstract: Equipment for regulating the pressure and compensating for the movement of the shaft train of a drilling rig. The shaft train carrying the drilling tool is jointed to a hook, the vertical movement of which is controlled by a winch. The hook is mounted on a rigid frame inside a cage. The frame slides up and down relative to the cage, the upward movement being unhindered, the downward movement being against a force which is almost constant and which is predetermined dependent on the wt. of the shaft train. The equipment can be used at sea to compensate for the swell of the sea. It is advantageously used to compensate for variations in the speed of advancement of the drill due to variation in the composition of the strata. The equipment allows for immediate retardation of the lowering of the shaft train when the advancement of the drill slows, thus preventing damage to the drill. The automatic compensation by the equipment described gives time for the operator to make any necessary manual adjustments.

Title: pH indicator for use in aquarium - uses transparent receiver which is immersed in water and which contains liquid indicator
IPC: G01N31/22
Filed: 1976-09-06
Abstract: The device indicates the pH of the water in an aquarium. A transparent receiver (3) is immersed in the water (5) of the aquarium (1).

Title: PTFE insulation for an explosive collar for cutting pipes - to extend the pipe temp. range for collar applications
Inventor: TARRIEU CHRISTIAN JEAN HENRI
IPC: F42B15/38
Filed: 1976-09-17
Abstract: Explosive collars for cutting pipes or tubular structures where the explosive is contained in a compartment along the root of a 'V' section profile which is clamped with the mouth of the section towards the surface of the pipe to be cut. A sleeve of insulating material is interposed between the collar and the pipe: the charge size being increased sufficiently to sever the insulation as well as the enclosed pipe. Used for disengagement of spare rocket stages, activation of aircraft emergency systems etc., esp. involving pipes or conduits for transferring or circulating very hot or cold materials, i.e. outside the range -70 to +110 degrees C, e.g. up to 400 degrees C. The insulation and the gap between the explosive charge and the pipe wall prevents overheating or excessive chilling of the explosive or the detonator system.

Title: High pressure hydraulic hose mfr. - using induction heating of metallic wire reinforcement to bond inner and outer extruded tubes
IPC: F16L11/08
Filed: 1976-09-21
Abstract: Reinforced rubber or plastic hose consists of inner and outer layer tubes and metallic filament or strip reinforcement between the tubes. The assembly has been bonded together by electric induction heating. Such hose is made by wrapping the reinforcement, embedded in elastomeric material which is compatible with the tubes, round an extruded inner tube, applying the water tube, and passing the assembly through an induction device so that the elastomeric material reaches melt temp. to effect bonding. Used e.g. for high pressure hydraulic hose. The hose is simpler and less costly to make than where mandrel and autoclaving under constant are used. The hose will withstand pressure shock loading. "Cheese cutting" of the tubes and air entrapment are avoided.
