摘要:
Attenuated respiratory syncytial virus (RSV) and vaccine compositions thereof are produced by introducing specific mutations associated with attenuating phenotypes into wild-type or RSV which is incompletely attenuated by cold-passage or introduction of mutations which produce virus having a temperature sensitive (ts) or cold adapted (ca) phenotype. Alternatively, recombinant RSV and vaccine compositions thereof incorporate attenuating and other mutations specifying desired structural and or phenotypic characteristics in an infectious RSV. Recombinant RSV incorporate desired mutations specified by insertion, deletion, substitution or rearrangement of a selected nucleotide sequence, gene, or gene segment in an infectious RSV clone. The immune system of an individual is stimulated to induce protection against natural RSV infection, or multivalently against infection by RSV and another pathogen, such as PlV, by administration of attenuated, biologically derived or recombinant RSV.

The present invention concerns an article holder for a child seat, the holder comprising a holder portion (6) for holding one or more articles, and a mounting (7) in relation to which said holder portion is movably mounted. The holder portion and said mounting are configured for relative sliding movement there-between along an arcuate path.

The present invention relates to a ground anchorage head assembly (10) for an anchorage tendon (15), the head assembly comprising a bearing plate (11); and a resilient coupling (11, 12), for coupling the bearing plate to said tendon, said resilient coupling having a non-linear stiffness characteristic.

A single lever valve for mixing hot and cold liquids has a mixer which can internally impose an upper limit on the temperature of any liquid emerging from it. The means used may enable the upper limit to be changed by exchange of a component so that the mixer can be used in any location in an installation even though different locations might have different upper limit requirements. The mixer may take the form of a cartridge able to be exchanged with an existing cartridge to convert an 'unsafe' mixer to a 'safe' one. There is a cylindrical mixing chamber with hot and cold liquid entry through ports through the side walls at opposite ends. A piston sealingly slidable within the chamber effects opening and closing of the ports.

A child safety seat (100) and support (30) are provided where a connector (38) between the seat (100) and the support (30) allows the seat to pivot relative to the support to change the pitch of the seat (100) . The connector (38) may¬ be locked in a chosen position thereby fixing the pitch of the seat . A further connector (58,70) attaches the seat to the support and fixes the position of the seat relative to the support. The further connector (58, 70) may move in a linear fashion to accommodate the change in pitch. The seat (100) can be connected to the support (30) in a rearwards or forwards facing orientation.

A child safety seat (1) for a vehicle, such as a car or bicycle, comprising a seat base (5); two side supports (3), provided respectively on opposing sides of the seat (1), said side supports (3) and seat base (5) defining a user area for receiving a user; and a moveable panel (4) provided on at least one of the side supports (3); wherein the or each moveable panel (4) is adjustably extendable from its respective side support (3) into the user area for supporting the user at the sides.

The present invention concerns a tension indicator (10) for a strap; the tension indicator comprising a first part (11) for receiving a length of the strap, a second part (12) movably mounted with respect to the first part between open and closed positions, the second part having strap engagement means (23) for engaging said length of strap. The strap engagement means is biassed relative to the first part for pulling any slack in the strap into the first part, thereby allowing the second part to move to said open position.

A tension indicator comprises a housing (1) mountable on a strap S which passes through mouths (5) and (6) of the housing. Within the housing, a barrel (11) is rotatably mounted upon a transverse axis (A). The barrel has a cross-passage (12) for strap (S). Towards its ends barrel (11) has discs (14), carrying slot (15) defining formations (16). The slots engage springs (21). The arrangement is such that in the relaxed state of the springs, barrel passage (12) is out of alignment with mouths (5) and (6), so that a strap (S) passing through the tension indictor is deflected to a lazy Z path . The housing has a window (23), through which barrel (11) can be seen. When springs (21) are relaxed, a “SLACK” portion (24) of barrel (11) can be seen through window (23). When strap (S) is tensioned it is straightened by abutting on ends (25) of passage (12). A different “TENSIONED” portion (26) of barrel (11) now becomes visible in window (23). Thus the tension is strap (S) can be assessed according to which of the portions (24) and (26) is visible in window (23).

This invention relates to a novel process of making of a positive image producing film by using an inkjet printer commercially available in the market and using a clear film coated with an ink receiving layer as described in this invention. It further describes the method of producing such a clear film for the purpose of using it as a positive for making printing masters for various printing applications.
