Abstract: Abstract A motion compensator for disposition between an offshore support and an offshore well string or the like movable with respect to the support comprises first and second compensator bodies interconnected with the support and the well string such that relative movement between the support and well string causes relative movement between the compensator bodies.  The compensator bodies are further interconnected with each other for relative movement in generally vertical directional modes. A compressible fluid or the like is associated with the com-pensator bodies for resiliently resisting relative movement therebetween in a first directional mode. A position indicator associated with the compensator bodies comprises a flexible vessel having one end connected to one of the compensator bodies and the other end connected to the other compensator body generally below the one end. The vessel is filled with a liquid between its two ends, and a pressure sensitive transmitter is associated with the lower end and operative to produce a signal which is a function of the hydraulic head at said lower end

Abstract: ABSTRACT     The invention concerns a cigarette having an external-heat-deformable, paper wrapper comprising a proportion of thermoplastic fibres or filaments, the peripheral conform-ation of the cigarette having been modified by the applic-ation of heat to the wrapper.  The proportion of thermo-plastic fibres or filament  in the wrapper is suitably not less than 40% by weight.  The modification of the conform-ation of the wrapper may have been such as to provide an embossed-pattern effect over a portion or portions of the surface thereof or to produce a groove or grooves extending around and/or along the cigarette.  In the case of a tipped cigarette, the modification of the conformation of the wrapper may comprise such deformation of a tipping wrapper as to improve the grip thereof on the tip and/or cigarette or to form flats on opposite sides of the tip.    The invention also includes a method for modifying the peripheral conformation of a cigarette in which the cigarette, which has an external, heat-deformable, wrapper comprising a proportion of thermoplastic fibres or filaments, and a heated forming means are relatively moved in contact with each other in a direction transverse to the longitud-inal axis of the cigarette.  If the cigarette moved in contact with the heated forming means is a double-length filter-tipped cigarette, a tipping wrapper enwrapping the full length of the filter element and a short length of each of the cigarette rods may thereby interattach the same.

Abstract: FLUID LEVEL MEASURING SYSTEM          ABSTRACT A system for measuring the level or volume of a fluid within a fluid storage vessel which comprises: a multi-capacitor  type fluid level sensor formed of a pair of capacitors of fixed and substantially like capacitive value and two capacitors having like open dielectric spaces for receiving varying levels of the fluid within the vessel and with the fluid in the spaces consisting of a pair of capacitors of variable capacitive value.  The four capacitors of the sensor are connected together to form the four capacitive sides of a Wheatstone bridge circuit  the pair of fixed value capacitors connected as two opposing sides of the bridge and the pair of variable value capacitors connected as the remaining two opposing sides of the bridge.  A source of alternating current of constant voltage and set frequency is applied across the bridge circuit to a first set of bridge terminals at opposite corners of the bridge  each of such terminals located between a fixed capacitor and a variable capacitor of the sensor. A detection circuit is connected across the bridge to a second set of bridge terminals (independent of said first set of terminals) and at opposite corners of the bridge  each of such terminals located between a fixed capacitor and a variable capacitor of the sensor.  The current value in the detection circuit is measured and indicates the value as a fluid level or fluid volume measurement in direct linear relationship with the current value.  The system is not limited to fluid level or fluid volume measurements -i-of liquids in vessels and may be used for volume measurement with respect to a wide variety of multi-component systems (including liquid/liquid, liquid/gas, liquid/solid, solid/gas, etc.) as long as the dielectric constants for the two or more components are different.     The invention also encompasses a method for measuring the level or volume of a fluid within the fluid storage vessel, and further encompasses a fluid level or fluid volume sensor or probe for mounting in the fluid storage vessel for sensing the level or volume of the fluid within that vessel.          -ii-

Abstract: RAFT INFLATION VALVE A raft inflation valve includes a valve body having an inlet, an outlet, an internal cylinder open at one end to the valve outlet, and an inlet passage leading from the valve inlet to and intersecting with the midsection of the internal cylinder. A double-ended balanced piston with O-ring seals on both ends is positioned in the internal cylinder so that one end blocks the passage to the outlet. In this position (valve closed) the O-ring seals are on opposite sides of the intersection of the inlet passage which results in a balancing of the gas pressure forces acting on the piston. When the valve is actuated, a firing mechanism causes the piston to move away from the outlet end of the internal cylinder so that the piston head partially uncovers the outlet passage. Once the outlet passage is partially uncovered, the gas pressure forces on the piston become unbalanced and the pressure rapidly accelerates the movement of the piston the remaining distance out of the passage, which then allows the inflation gas to flow freely through the valve to the raft.
