A variable-speed passenger transporter for conveying passengers from a stationary surface to a belt moving at constant speed, which includes a plurality of rhomboid platforms driven along guide means in a closed circuit along a section of which the platforms are in contacting relationship to form a moving floor. Along the initial portion of this section the platforms travel at low speed and at right angles to their center lines towards the belt but at an angle thereto. Along the following portio...

A method is disclosed for preparing an elastomeric composition comprising: (I) mixing (A) a silicone base comprising a curable organopolysiloxane, (B) an optional crosslinking agent, (C) a cure agent in an amount sufficient to cure said organopolysiloxane; (II) mixing the product of step (I) with (D) a fluorocarbon elastomer, (E) an optional compatibilizer, (F) an optional catalyst, and (III) statically vulcanizing the organopolysiloxane, wherein the weight ratio of fluorocarbon elastomer (D) to...

An ink-jet hard copy apparatus provides a flow of air across the printing surface of a sheet of print media during printing operations. The airflow scrubs the boundary layer of the printing surface such that paper cockle is reduced by resultant improvement in drying time. A writing instrument deflector is used to prevent substantial interference with ink droplet flight trajectories due to positive airflow through the print zone.

A seat conveyor system is incorporated in a large room for moving persons over the floor area from a designated entrance area to a designated exit area adjacent to a plurality of service windows in the room. The arrangement is such that individual persons entering the entrance area can be seated while waiting in line for service at any one of the service windows.

An image recording apparatus includes an ink jet head which ejects ink toward a recording medium to record an image thereon, a paper feed unit which feeds the recording medium, a recording medium conveyance unit which conveys the recording medium, an intake fan provided at the recording medium conveyance unit to adsorb the recording medium by negative pressure, and an exhaust fan to remove dust from between the paper feed unit and the recording medium conveyance unit. The image recording apparat...

A silicon-based interband tunneling diode (10, 110) includes a degenerate p-type doping (22, 130) of acceptors, a degenerate n-type doping (32, 118) of donors disposed on a first side of the degenerate p-type doping (22, 130), and a barrier silicon-germanium layer (20, 136) disposed on a second side of the degenerate p-type doping (22, 130) opposite the first side. The barrier silicon-germanium layer (20, 136) suppresses diffusion of acceptors away from a p/n junction defined by the degenerate p...

A method for providing customized digital printing services over a network to provide a photo product including images including providing an electronic database of information describing a plurality of photo product options that can be selected by a user via a digital communications network and displaying at a location remote from the electronic database the plurality of photo product options. The user provides a first group of digital images and selects at least one photo product from the plur...

Briefly, in accordance with one embodiment of the invention, a combiner may include transmission lines to couple a receive port and a transmit port to an antenna at a common junction. Shunt admittance elements may be utilized at the transmit and the receive ports to isolate one of the transmit and the receive ports from the antenna by shunting the at least one of the transmit and the receive ports to a power supply potential such as a ground reference. During a transmit mode, the shunt admittanc...

A ceramic tubesheet pierced by a plurality of hollow, glass fibers and consisting of sintered particles is rendered essentially impermeable by selectively fusing the portion of the tubesheet subjacent to and defining one of its surfaces. The fiber lengths extending from the opposite surface of the tubesheet are freer to flex and less likely to be broken than if the entire tubesheet were fused.

Conveyor having low-speed and high-speed zones, and a connection zone there between, comprising a series of load-carrying platforms slidable one against the next to effect acceleration in the connection zone, wherein each platform is provided with connectors for linking it to the two adjoining platforms in the connection zone, a drive mechanism for the connectors being provided to effect movement thereof relative to their respective platforms, whereby progressive sliding movement of each platfor...
