A drainpipe (4), for hot or cold water, which passes through a thin wall (1), is supported on the wall by a fitting (5) which is enclosed in a housing (9). This housing is made in two parts (10,11) which are fastened to each other by the nails or screws which attach the housing to the wall. The housing is so shaped that it grips the corrugated tube (3) which protects the drain pipe. The housing is...

"Improvements Relating to the Manufacture of Tobacco Smoke Filters" A particulate plastics material, a polysaccharide and water are fed to an extruder which is operated under such heat and pressure conditions that upon emergence of the extrudate from the extruder die, the extrudate assumes a cross-section greater than that of the exit orifice of the die.

The use of falling-film evaporation and a concentration means such as centrifugal separation to dehydrate and concentrate a water-in-oil polymer emulsion or suspension is disclosed. In a preferred embodiment, a water-in-oil polymer composition containing less than about 25% active polymer solids is dehydrated in falling-film evaporator to produce an evaporator concentrate containing less than abou...

The present invention relates to chimeric neurotrophic factors which comprise at least a portion of a naturally occurring cellular factor and a portion of at least one other molecule such that the resulting chimeric molecule has neurotrophic activity. It is based, in part, on the discovery that chimeric molecules comprising portions of both NGF and BDNF are likely to possess neurotrotrophic activi...

A coder assembles bursts of blocks of image data (eg transform coded coefficients) and associated overhead data into a sequence of data which are then transmitted. Both the transform coded coefficients and the overhead data are initially stored in separate FIFO memory stores (21)(22). The blocks of transform coded coefficients have a 'last coefficient' flag accompanying the last coefficient, and t...

A fixation element for securing a prosthesis in a bone, whereby the effective diameter of the fixation element can be increased by increasing the temperature of at least one element of a material which shrinks or expands when heated, such as shape memory metal, by means of an inductive magnetic field, whereby the change in shape generated with the shrinkage or expansion of the material is converte...

(-)-Cis-4-amino-1- (2-hydroxymethyl-1,3 -oxathiolan-5-yl)-(1H)- pyrimidin-2-one (I) and its derivs. are new. (I) contg. max. 5 wt% of (+)-enantiomer (pref. below 1 wt%) is also claimed. (I) is prepd. by sepn. from a racemic mixt., preferably by chiral HPLC. The stationary phase used is preferably beta-cyclodextrin or cellulose triacetate. Alternatively sepn. is by enzyme-mediated enantioselective ...

Process and apparatus for heat regulation of fluidised or moving catalyst beds, the apparatus comprising a heat exchanger with a fluidised or moving bed. According to the invention a pulverulent solid is circulated essentially from the base of a vessel (1) in a heat exchanger (6) comprising an internal separating partition (22) which defines two elongate and adjacent compartments (23, 24) com...

To reduce the nitrate content in groundwater, drinking water or surface water, bark mulch (12) is introduced into the ground (10). To achieve a large surface area, bark mulch is used in a particle size of smaller than 20 mm, and it is further proposed that bark mulch is mixed with granulated clay and lava. The bark mulch, or bark mulch mixture, results in nitrogen being bound and stored in the gro...

The invention relates to an endoprosthesis which has at least one hollow structure implantable in a bone bed and provided with openings, the hollow structure containing a filling which promotes bone growth and comprises a material which forms a porous matrix and contains one or more peptide growth factors. Such a prosthesis displays improved settling-in behaviour and has a longer life.

An SIR door and instrument panel are formed by adhering a single, unitary cover material over a preformed door insert member and separate preformed panel insert member. The insert members are sprayed with an adhesive and placed on a support member with the door insert member aligned with and raised above an opening in the panel insert member. The single, unitary cover material is laid over the ins...

The present invention relates to a water-resistant building material which comprises: 0.2 to 6 % by weight of water-proofing additive; 0.5 to 10 % by weight of fly ash; 0 to 5 % by weight of Portland cement; and the balance being gypsum and optionally at least one other additive, all of the above percentages by weight being based on the weight of the total composition. The present invention also p...

A prosthetic intramedullary femoral prosthesis (1) provided with a separate preformed sheath (9) made from an acrylic material which is dimensioned to enclose the prosthesis stem (4) from the distal tip (10) to a location on the stem (4) which will be adjacent the proximal cut end (6) of the femur (5) with which it will be used.

Compounds represented by the general formula (I), wherein R<1> is a saturated or unsaturated, straight or branched hydrocarbon radical [wherein the number of carbon atoms in the longest straight chain of this hydrocarbon radical ranges from three to seven], or a radical of the formula -(CH2)n-Y [in which n is an integer from 0 to 4, when Y is a cyclohexyl radical, or n is an integer from 2 ...

The compound of formula (I> has antiparasitic activity and is a useful intermediate in the preparation of other compounds having antibiotic activity.

A method of producing double-stranded nucleic acid derivatives having RNA as the parent body (the total molecular size distribution of which is from 4S to 13S expressed as sedimentation constant value of, alternatively, is such that the derivatives have base numbers in the range 50 to 10,000) including sizing nucleic acid polymers and subsequently combining them. Before combination the sized polym...

The invention relates to a plastic sleeve-joint tube comprising a tube element (1) of generally cylindrical shape, of specified, possibly standard, length, of constant diameter and having a ribbed outer structure with, in its outer surface (4), a succession of raised circular corrugations (5) which are separated by hollow grooves (6), one (7) of the ends of the element comprising, attached to this...
