Abstract:
A wall mounted vertical, gravity fed dispensing container for use with a blister pack includes a pair of perforated sheets defining a holder portion for receiving and supporting the blister pack while holding the blister pack parallel to the wall. The holder portion is formed as a separate element which can be snapped into the container. The two sheets are hinged at the bottom. Behind the holder portion is a catching container fixed to the holder portion and to the wall such that medication expelled from the blisters through the openings by a manually movable punch is caught in the catching container. A bottom wall of the catching container converges the medications to a bottom chute with a manually movable press lever operating a flap valve to discharge the medications into a cup. A front door covers the holder and the blister pack and contains a receptacle for the punch.
Abstract:
A composite article and its method of manufacture are disclosed. The composite article includes a matrix formed of a mixture of glass particles and a cured polymer, and a layer of cured polymer material that is substantially free of the glass particles, said layer being formed on at least one surface of the cast article whereby the glass particles are not surface exposed on the at least one surface.
Abstract:
A method for joining components comprises locating a region, such as an end region 24, of a shape memory alloy (SMA) material component 10 adjacent to a further component 12, and generating localised plastic deformation of the aforesaid region to create a joint between the components 10, 12. The localised plastic deformation of the shape memory alloy material component 10 is preferably generated by applying a shock load to the shape memory alloy material component 10.
Abstract:
A method and a system (10) for exhausting gas via a nozzle (19, 21) of a gas turbine engine, for example. The system (10) comprises a nozzle (19, 21) comprising a nozzle body portion (32, 33, 74) defining a nozzle exit (42, 43), characterised in that the nozzle body portion (32, 33, 74) comprises fluid injection means (60), positioned upstream of the exit (42, 43) relative to a fluid flow (F1, F2) created by the operation of the system, for injecting fluid (68) upstream of the exit (42, 43).
Abstract:
A seal (40) provides sealing between two pressure zones (60, 62) and a rotating and non-rotating member (42, 52) by providing a first sealing member (46) between two seal lands (48, 50). A second seal (64) is mounted between the non-rotating member (52, 58) and one of the seal lands (50, 66) so as to control pressure around the seal lands (48, 50).
Abstract:
An anchorless boat positioning system for establishing and maintaining a boat at a selected geographic location without the use of a conventional anchor. In one embodiment, a steerable thruster is used whose thrust and steering direction are determined and controlled on the basis of position information signals received from global positioning system (GPS) satellites, relative steering angle between the boat and the thruster and boat heading indication signals from a magnetic compass. The system continuously monitors the position and heading of the boat and compares it with the stored coordinates of the selected anchoring location(s) to generate control signals for the steerable motor. Several modes of operation are disclosed and Euler transformations for offset antenna placement for error reduction are taught. Proportional, integral, and derivative control (PID) of four constants of vessel control is also provided. Multiple thrusters in various arrangements are also provided to control either the orientation of the boat or a second point of interest on the boat at a second geographic location.
Abstract:
An electronic assembly is provided that has a housing receiving a motherboard arranged, in use, to carry control circuit components, and a circuit board carrying a lightning strike protection circuit, said circuit board including a first electrical connector, and the assembly further including a flexible cable electrically connected to the motherboard, the cable including a second electrical connector arranged to cooperate with said first electrical connector to electrically connect the lightning strike protection circuit to the motherboard, said first and second connectors being accessible from outside of the housing. The assembly may be used in aerospace applications.
Abstract:
An apparatus and system are disclosed for indicating relative positions of elements in a surgical apparatus. The indicating elements can include electrical circuitry for activating visual, audible or tactile indicators, thereby alerting the user that an event has occured with respect to the instrument.
Abstract:
A method of fighting fires which comprises applying to the fire a foam produced from an aqueous composition comprising as a surface-active agent the residue of a branched oligomer of tetrafluoroethylene (C.sub.2 F.sub.4).sub.n wherein n is 4, 5, or 6 having a hydrophilic group attached to the residue of the oligomer, said oligomer having at least three CF.sub.3 groups and being characterized by a formula selected from the group consisting of: ##STR1## The surfactants are particularly effective when incorporated in foams derived from other foam-producing materials.
