Title: Monitoring fluid pressure in a flexible pipe
Inventor: SHARPE JOHN ERNEST ELSOM
IPC: G01L9/00
Filed: 1986-11-27
Abstract: In order to measure fluid pressure in a flexible pipe (20), the pipe is squashed between two jaws (12, 14) joined by a bridge (16). The compression of the pipe between the jaws causes a strain to be set up in the bridge which can be measured by a strain gauge (28, 30) connected to the bridge. As the internal pressure in the pipe changes, so the strain detected by the strain gauge will change and this produces an output representative of the pressure variations in the pipe. The temperature of the pipe contents can also be monitored by temperature readings taken from the pipe exterior.

Title: Non-contact measurement of distance to and between surfaces of an object
Inventor: VELTZE JANUSZ ANDREW
IPC: G01B11/02
Filed: 1987-05-11
Abstract: Non-contact measurement of the distance of the surface 110 of an object 103 is made by observing the lateral offset of a spot of light on the surface projected obliquely on to the surface from a light source 101. The distance between the light source and the surface of the object in the direction to be measured is adjusted, e.g. by means of a carriage on which the source is mounted, until the light spot appears in a predetermined lateral position on a plane 114 when the position of the light source relative to the surface is known, e.g. by means of a transducer 104. The difference between the outputs of two adjacent light sensitive devices observing an image of the light spot provides an indication of the lateral offset. The light may be led to the detectors via optical fibres and the outputs of the detectors fed to a comparator 108. Two additional light sensitive devices having the same field of view except for a central opaque spot may be used effectively to restrict the response of the first-mentioned devices to only the area of the central opaque spot. <IMAGE>

Title: Delivery systems for pharmacological agents
Inventor: STEINER SOLOMON S
IPC: A61K9/16
Filed: 1988-12-30
Abstract: Methods for targeting the release of an active pharmacological agent in an animal by administering that agent encapsulated in proteinoid microspheres which are stable to the environment encountered from the point of introduction until they migrate to the targeted body organs, fluids or cells and are there unstable. Orally administered delivery systems for insulin, heparin and physostigmine utilize encapsulating microspheres which are predominantly of less than about 10 microns in diameter and pass readily through the stomach wall and which are made of an acidic proteinoid that is stable and unaffected by stomach enzymes and acid, but which releases the microencapsulated agent in pharmacologically active form in the near neutral blood stream. Basic proteinoid microspheres encapsulating a dopamine redox carrier system are administered in the lower gastrointestinal tract, where they are stable, and then enter the blood stream, where the encapsulated agent is similarly released.

Title: Stabilisation of an element against oxidation during a solvent extraction process
Inventor: MILES JOHN HEDLEY
IPC: C22B3/06
Filed: 1989-04-06
Abstract: An element (e.g. Pu) is dissolved in a first oxidation state (e.g. as Pu (III)) in a mixed phase system comprising an aqueous nitric acid phase and an organic liquid phase. The element in that state is only partly extractable or is not extractable from the aqueous phase into the organic phase, and is oxidisable in aqueous nitric acid to a higher oxidation state (e.g. as Pu(IV)) in which it is extractable from the aqueous phase into the organic phase. The element is stabilised in its first oxidation state by a substituted urea dissolved in the aqueous phase. Such stabilisation may be used to separate the element from other elements (such as U) which are readily extractable from the aqueous phase into the organic phase in certain oxidation states.
