Fluid mattresses
An air inflatable mattress (10) for medical and hospital use is formed from upper (12) and lower (14) layers of flexible, air impervious material joined at a peripheral air impervious seam (20); laterally extending, elongate, spaced apart pillows (18) extend between side edges of the mattress (10) and are defined by lateral folds formed in the material of the upper layer; the pillows (18) communicate at their opposed ends with longitudinally extending side plenums (16); the inflated pillows (18) billow against each other in stress relieving contact effective to relieve air pressure bursting forces generated in the mattress.

Arrangements for treating drilling fluids outside the borehole
Drill cuttings contaminated with hydrocarbon, such as diesel oil, kerosene or mineral oil, from residual drilling mud are cleaned up to a solid particulate form containing very low amounts of residual hydrocarbon by means of an integrated four-step treatment process. In the first step (10), the cuttings are conditioned to destroy the complex fluid structure of the material and to break up agglomerations and clumps of solid particles into individual particles. Preferably this is accomplished by addition of a compatible hydrocarbon diluent under shearing agitation. Secondly, the destabilized contaminated cuttings are subjected to centrifugation (12) to separate excess liquid. Thirdly, the residual solids are treated, preferably under shearing agitation, with water and an appropriate wetting agent at low concentration (14) to displace residual surface hydrocarbon contamination. Fourthly, the treated cuttings are subjected to a final phase separation step (16), e.g. by centrifugation of the total stream, or by screening and washing the coarse fraction followed by washing and filtration of the fines fraction. The resultant solid material has a residual hydrocarbon content of less than about 6 grams per 100 grams of dry cuttings, largely in a form where it is unlikely to migrate out of the solids to harm the environment, under normal environmentally experienced conditions.

Writing-tables
An office desk system or work station is based on a structural supporting frame or chassis made up of two spaced parallel end gables and a beam extending between the gables at the rear edge of a work top. Each gable is a welded assembly of steel channels and the beam is a steel generally box section member. Decorative cladding is attached to the frame to provide the desk with the required external appearance. The beam has two internal wiring channels so that electrical power and telecommunication services can be provided directly at the work surface of the desk. Disconnectable couplings are provided between the beam and gables and each gable is provided with several coupling points so that many different desk system or work station configurations can be assembled from the same basic components.

Transferases (2.)
Specific sialyl transferases (ST) are important enzymes in the manufacture of carbohydrate moieties useful for pharmacological purposes and for diagnostic and clinical procedures. The invention offers simplified methods to isolate highly specific forms of these ST enzymes by taking advantage of the affinity of the ST for its acceptor substrate in the presence of the sialyl-CMP analogs, such as CDP. Specifically exemplified are isolation of the alpha 2,3-ST, specific for Lec or LacNAc, and alpha 2,6-ST, specific for LacNAc.

A floor covering element designed particularly for attachment to a decking plank comprises a narrow strip (19) of a textile carpet material. Needle punch material is preferred in view of its stability. The needle punch material carries a plurality of staples (24) at the side edges of the strip arranged transverse to the length of the strip and carried by a layer of adhesive film (27, 28, 29) through which the prongs of the staples project for engagement with the wooden surface of the plank (14).

An ice skate runner which may be removeably secured to a blade holder which forms part of an ice skate blade assembly. The runner is formed as a thin replaceable flexible strip arranged to be secured to said holder. The top surface of the strip has a configuration which is complementary to the lower surface of the holder so as to prevent lateral displacement of the strip with respect to the holder. Means are provided in the front and the rear of said holder to hold the strip in place and to create tension along the entire length thereof.

An angioplasty catheter (20) having a body (22) formed initially from an extrusion having dual lumens (34, 36) and which is then drawn through a die to reduce the cross-section thereby enhancing the surface finish and molecular orientation of the body. The result is a catheter having a main body of minimized crossed-section with good strength, torque, stiffness and resistance to kinking characteristics.

A colour calibration sheet, colour vignettes and transitions for use in calibrating a colour system. The sheet, vignettes and transitions may be in reflective or transparency print reflective or transparency proof, or digital or film separation form. An original of the calibration sheet is compared to an output from the colour system to determine errors in calibration of the system. The vignettes are visually continuous transitions from one colour to another. The vignettes may be linear or circular. Other transitions are juxtaposed pairs of transitions from a primary or secondary colour to the colour black where one transition uses the colour black and the other uses a secondary or primary colour, respectively.
