Abstract: A number of anchoring elements (4), consisting of an annular body (5) and a spacer (14), are arranged in a row on the shank (1) of the fastening element. These anchoring elements (4) are fixed in an axially immovable manner between a stop (9) of the shank and a locking section (12) of the same. The anchoring elements (4) exist as components separated from the shank (1) and are merely arranged in a row on the shank (1). In consequence, by means of one embodiment of the shank (1), a large number of differently constructed anchoring elements (4) can be used, which considerably reduces the cost of production and increases the universal applicability of the fastening element. In particular, the shank (1) and the anchoring elements (4) can be produced from metal, so that the fastening element can overall have much greater strength in comparison with previous plastic elements.

Abstract: A dry-state iontophoretic drug delivery device (10, 20) is provided. The device has drug and electrolyte reservoirs (15, 16) which are initially in a non-hydrated condition. In one embodiment of the invention, a passageway (21, 22) is provided through the backing layer (13) and the electrode layer (11, 12) of both the donor electrode assembly (8) and the counter electrode assembly (9). Water or other liquid can be introduced through these passageways (21, 22) in order to hydrate the drug and electrolyte reservoirs (15, 16) and activate the device (10). In another embodiment of the device (20), the drug and electrolyte reservoirs (15, 16) are initially separated from their respective electrodes (11, 12). After the reservoirs (15, 16) are hydrated, they are placed in electrical contact with their respective electrodes (11, 12). By joining the reservoir (15, 16) to the electrode (11, 12) after hydration occurs, delamination problems are reduced.

Abstract: An immunogen for eliciting an immune response to antigens, particularly normally weakly-immunogenic viral antigens, such as the haemagglutinin antigen (HA) from influenza virus contains the antigen in two different physio-chemical forms. The immunogen may comprise one composition containing the two antigen forms or there may be two compositions containing respective antigen forms. Administration of the immunogen to an animal at one or more sites gives an enhanced immune response compared to the immunogen comprising only one of the two antigen forms.

Abstract: An oil filter utilizes a thermoplastic material having oil oxidation and acidification arresting additives mounted in a casing between a particle filtering material (such as cotton fibers) and a felt pad. The thermoplastic material is desirably high molecular polypropylene in the form of rice-shaped pellets, or spaghetti-shaped strands. The additives comprise about 10-17 weight % of the thermoplastic material/additive combination, and as the thermoplastic material is dissolved by above ambient temperature oil, the additives are released. The thermoplastic material pellets or strands are formed by mixing anti-oxidation and anti-acidification additives with liquid thermoplastic material to form a mixture, extruding the mixture into spaghetti like strands having a thickness of about 0.0625-0.125 inches, cooling the strands, cutting the strands into discrete elements, and then placing the discrete elements into an oil filter held in place to contact oil and to gradually dissolve to release the additives.

An aircraft has at least one forward propulsion engine and an additional propulsion unit which is mounted so as to be movable between a position in which it is disposed within the fuselage of the aircraft, and a further position in which it is disposed externally of the aircraft so as to be capable of producing lift forces on the aircraft independently of those produced by the aerodynamic surfaces of the aircraft, during forward flight thereof or forward propulsion. the arrangement being such that the thrust produced by the or each additional propulsion unit can be directed rearwardly of the aircraft to enable transition of the aircraft from vertical to forward flight to be effected. The fuselage 10 houses two by-pass jet propulsion engines 12 having a jet deflector 29 in each jet pipe 28 for deflecting gases into pipes 26 which lead to a plenum chamber 30. Further, vertical, jet propulsion engines 25 exhaust into a plenum chamber 31 connected to chamber 30 by conduits 34.
