A valve assembly (52) has a valve housing (64) which fits in neck (76) of container (50). Valve member (88) is slidably movable in housing (64). Housing (64) has a plurality of grooves (86) and apertures (80), which interact with flanges (92, 94, 96) to define flow paths in the valve assembly (52). The flanges (92, 94, 96), inside surface (84), apertures (80), slots (86) and valve member (88) provide a flow path through the valve assembly (52) when the valve member (88) is in its downward positi...

A character recognition system comprising means for scanning a character on a document field, the field being composed of plural features each of which lies in a respectively defined area on the character. A pair of video shift registers, one for positive video and one for negative video, are provided to shift the signals therethrough. Each video shift register includes a plurality of stages for serially storing and shifting a binary quantization of a character pattern sample within said field. ...

A package (10) for dispensing a fluid (26) in the package under gas pressure has a biaxially oriented polyethelene terepthalate bottle (12) with a neck (14). A dispensing head (22) is attached to the neck (14). A normally closed valve (16) is mounted in the neck and has a housing (50) sealed to the inside surface of the neck (14). The housing (50) has a syphon flange (54). An integral structure (56) having a spring (58) at one end and a poppet (60) at a second end rests on the syphon flange (54)...

A lift truck is provided with a lift mast having a horizontal slewable load carrier. In one aspect of the lift truck the body thereof is provided with an operator's cab having a load bearing roof onto which the load carrier can lower its load after being horizontally slewed to a laterally facing position. In another aspect of the lift truck, the fixed and movable upright guides of the lift mast are aligned longitudinally of the lift truck with the load carrier being mounted to the movable guide ...

Apparatus for thermal coagulation having an improved circulation assembly and heating assembly. The apparatus includes a balloon catheter secured to and in fluid communication with a handle for inserting the apparatus into a human uterus. A distensible bladder is secured to the distal end of the catheter and encloses a heating assembly having a tubular core configured with a spiral groove which retains a heating filament. An impeller having at least two blades is positioned distal of the heating...

In one aspect of the lift truck the body thereof is provided with an operator's cab having a load-bearing roof onto which the load carrier can lower its load after being horizontally slewed to a laterally facing position. In another aspect of the lift truck, the fixed and movable upright guides of the lift mast are aligned longitudinally of the lift truck with the load carrier being mounted to the movable guide ...

A valve (20) has a valve housing (22) with a central passage (28) extending axially through the valve housing (22). Aperture (40) in the valve housing connect a second passage (38) to the central passage (28) to extend through the valve housing. A poppet valve member (24) is configured for sealing engagement of the central passage (28). The valve member (24) is urged into sealing engagement with the central passage (28) by internal pressure in a container (36) on which the valve (20) is provided...

Laser radiation can be directed through an aperture to a target surface without causing the expected diffraction groove effect by moving the target relative to the stage to which the aperture is attached in such a fashion as to interrupt the diffraction pattern and minimize the production of diffraction grooves.

A method and system of forming vertical optical interconnects in optical integrated circuits is disclosed. The method includes forming a first optical transmission layer over a substrate. A first cladding layer is then formed on the first optical transmission layer and portions of the first cladding layer removed to form an angled sidewall in the first cladding layer. An optical interconnect layer is formed on the angled sidewall of the first cladding layer and on an exposed portion of the first...
