Abstract: A system and method uses an appliance for delivery at a home or business when no one is home or without the need to disturb persons at the delivery site. The appliance is a locked storage container connected to remote computers such that access for particular delivery persons or companies is authorized when the owner of the appliance has placed an order. The appliance communicates, such as via the internet, with a remote delivery system computer having a scheduler that schedules deliveries during particular time intervals. Prior to scheduling the delivery, the delivery system computer compares the dimensions of the order with the available space within the appliance of the customer. After a delivery is made, the appliance communicates via the internet that the delivery has been made and the delivery system computer then charges or debits the customer's account for the cost associated with the delivery.

Abstract: Immunogenic compostions composed of poxvirus immunogens and related methods are disclosed. Specifically, immunogenic compostions useful in eliciting immune responses in animals are disclosed. In one embodiment the immunogenic compostions include viral antigens derived from vaccinia and/or variola that elicit cross-reactive immune responses. The immunogens can be made synthetically, by using recombinant DNA technology or derived from purified virus. Moreover, methods of using the immunogenic compostions are also disclosed.

Abstract: Methods and compositions are described for treating contaminants in material intended for in vivo use, and in particular blood and blood products for human use. Contaminants in blood cell preparations are inactivated prior to long term storage and transfusion. Inactivation is accomplished using a device having a unique temperature control design.

Abstract: The present invention relates to an apparatus and method for removal of arsenic or other metal salts from drinking water. The invention uses a bed of granulated ferric hydroxide to adsorp the metal in a pressurized adsorption chamber. The bed is sized to about 10 m3 and run with an EBCT of about 3 minutes which has been found to give an unprecedently long bed life of upto 200,000 bed volumes of treated water.

Abstract: In a safety razor a blade unit (1) is mounted on a carrying structure (2) for pivotal movement, and a delivery system (25,32,44) for conducting from a reservoir (21) a fluid, e.g. a lubricating fluid, which is to be applied to the skin during shaving, discharges the fluid at a port (45) which opens at or close to the pivot axis. The delivery system incorporates a valve (22,24) to control the supply of fluid to the blade unit (1) and the blade unit carrying structure (2) is coupled to the valve for the valve to eb actuated in response to the blade unit (1) being pressed against the skin during shaving. The blade unit carrying structured (2) is connected to a support structure (35) by a hinged coupling (36) and the valve is operated by a hinged movement of the blade unit carrying structure (2).

Abstract: The invention relates to shaving and is concerned with a blade formed from a single crystal ceramic material. The blade presents a sharp cutting edge and support elements are provided for mounting and positioning the blade (cutting element) in a blade unit. A guard element is disposed forwardly of the cutting edge and extends parallel thereto. A plurality of parallel cutting elements may be provided. The invention also concerns a method of making the cutting element.

Abstract: Methods and apparatuses for measuring visual acuity. In one embodiment, a moving fixation target is displayed. A series of optotype letters appearing offset from the moving fixation target is also displayed, and each optotype letter corresponds to a visual acuity. Each optotype letter appears in one of four possible random quadrant locations adjacent the moving fixation target, and each optotype appears only for a limited time.
