Abstract: There is described a method of communicating over a public data network, for example the Internet. A user of a public PC, for example one located in an Internet café, uses the Internet browser provided on the public PC to downloaded from a remote trusted web site a secure Internet browser that then runs within the browser provided on the public PC. The user uses the secure Internet browser to browse the Internet. The secure browser has been configured so that no copy of information transmitted into the network or downloaded from the network is cached or otherwise recorded on the hard disc of the terminal. The user may thus browse the Internet without leaving a record of sensitive information (e.g. credit card details) used in the browsing session at the public terminal.

Abstract: The present invention discloses a method, apparatus and system for electromechanical liquid dispensing. The system includes a bottle for holding liquid to be dispensed, the bottle having an inlet port and an outlet port, a one-way outlet valve on the outlet port through which liquid is dispensed from the bottle, and an electronic control system for controlling dispensement of the liquid from the outlet port such that a controlled quantity of liquid is dispensed.

Abstract: The blood sampling assembly includes a retractable double-ended needle so that a vial may be passed through an opposed end of the needle to obtain a blood sample. The assembly includes a hollow cylinder including circumferentially spaced seat tabs which allow a needle seat and the needle supported thereon to be released upon rotation of tube with respect to hollow cylinder. The extractor assembly includes a stopper for maintaining a vacuum within tube to withdraw the needle to a retracted position within the tube upon rotation of the tube, the end cap, and the stopper retainer. A stopper tab positioner rotationally connects the stopper to the cylinder.

Abstract: The blood sampling assembly includes a retractable double-ended needle 26 so that a vial may be passed through an opposed end 30 of the needle to obtain a blood sample. The assembly includes a hollow cylinder 10 including circumferentially spaced seat tabs 20 which allow a needle seat 40 and the needle 26 supported thereon to be released upon rotation of tube 62 with respect to hollow cylinder 10. The extractor assembly includes a stopper 66 for maintaining a vacuum within tube 62 to withdraw the needle to a retracted position within the tube 62 upon rotation of the tube 62, the end cap 92, and the stopper retainer 70. A stopper tab positioner 84 rotationally connects the stopper 66 to the cylinder 10.

Abstract: A hose sprayer assembly in accordance with the present invention includes a trigger body which is rotatably mounted within a housing. The housing is formed with an inlet orifice, an outlet aperture and an aspiration orifice, and further includes a deflector plate which is fixed to the outer surface of the housing proximate the outlet aperture. The trigger body includes a inlet port, an outlet port in fluid communication with the inlet port, and an aspiration port in fluid communication with the outlet port. Selective alignment of the trigger body places the inlet port and outlet port in fluid communication with the respective inlet orifice and outlet aperture of the housing. This yields a water only stream out the housing outlet aperture when water is forced through the assembly. Similarly, the body can be aligned to place the aspiration port in fluid communication with the aspiration orifice of the housing.
