Abstract: Sputtering targets with a working portion consisting of aluminium or a very pure-base aluminium alloy are disclosed. The targets are selected according to a suitable method, comprise no more than 0.1 internal splits larger than 0.1 mm per cm<3> of working target metal, and are particularly suitable for applications requiring very fine etching. An ultrasonic internal health testing method for producing such targets is also disclosed. In particular, the method comprises selecting an ultrasonic sensor operating at a working frequency higher than 5 MHz and preferably of 10-50 MHz, adjusting the appropriate measurement chain, then counting by size and number the internal splits per unit volume in a target that is immersed in a liquid and has a number of artificial flaws simulating splits in the target, and selecting the targets that have a split density of no more than 0.1 splits larger than 0.1 mm per cm<3> of working target metal, and preferably of fewer than 0.1 splits larger than 0.04 mm per cm<3> of working metal. Furthermore, sputtering target precursors containing fewer than 0.1 splits larger than 0.04 mm per cm<3> are disclosed.

IPC: B01D3/22
Filed: 1997-04-03
Abstract: A vapor-liquid-contact tray (26) is provided which includes a plurality of openings (38) and associated fixed roof structures (42) which redirect vapor flowing vertically upward through the openings (38) to horizontal flow paths.  Each fixed roof structure (42) includes a generally planar deflector (44) which overlies and is spaced above the associated opening in the tray. The deflector is joined to the tray (26) by end plates (46) connected at one end to the tray (26) and at the other end to the deflector (44). In one embodiment the deflector is generally parallel to the tray and divides the vertically flowing vapor stream into roughly equal oppositely flowing vapor streams. In other embodiments, the deflector (44) is inclined in relation to the tray to preferentially direct the vapor stream in one direction or to split the vapor stream into equal portions which are directed in the same general direction.  The openings (38) and deflectors (44) are arranged to more uniformly push the vapor and hence the liquid into and through those areas of the tray where liquid stagnation and gradients are a problem. The fixed roof structures (42) in the row of apertures closest to liquid receiving area at the inlet end of the tray are oriented so that the end plates shield the openings against entry of liquid leaving the receiving area. Louvre-type fixed roof structures (42) are used in association with at least some of the openings in the first row so that more rapid frothing of the liquid can be achieved with reduced incidence of liquid weeping through openings (38) in successive rows of openings.

Title: Method for forming a score in a strip of laminate, as well as a hinged angle section
Inventor: HEERTJES JOHANNES
IPC: B31F1/08
Filed: 1998-10-21
Abstract: A method for forming a score in a strip of laminate, for example cardboard, which laminate comprises a number of pressed-together 1 ayers, which are glued together, after which the score is formed in said strip of laminate. The application of glue between the various layers makes the strip of laminate being formed relatively soft. Then the score is pressed into the relatively soft strip of laminate, whereby the thickness of the score will be less than that of the strip of laminate.      Following that curing of the laminate takes place.

Title: Modified mcm-56, its preparation and use
Inventor: FUNG SHIU LUN ANTHONY
IPC: C10G35/095
Filed: 1997-06-09
Abstract: A layered composition of matter, MCM-56, has an X-ray diffraction including the lines listed in Table (II) and has been selectively modified so that the ratio of the num-ber of active acid sites at its external surface to the number of internal active acid sites is greater than that of the un-modified material. When used as an additive to a large pore zeolite catalyst in the catalytic cracking of a petroleum feedstock, the modified MCM-56 gives an improved gaso-line yield/octane relationship, an improved coke selectivity and a higher combined gasoline and potential alkylate yield than an identical catalyst containing unmodified MCM-56.

Title: Adhesive eyeglass nose bridge adjuster pads
Inventor: OEY DANIELA N
IPC: G02C5/12
Filed: 1999-04-23
Abstract: Adhesive Eyeglass Nose Bridge Adjuster Pads (AENBAPs) adjust the portion of eyeglasses in contact with the nose bridge by decreasing the allowable space for the nose to fit. They are to be used with eyeglasses without adjustable nose pads (ie: eyeglasses in which the frontal eyepiece portion is molded from one piece of plastic), and are intended for use by persons with a small or low nose bridge. The wearer simply peels off the backing of the adjuster pads, and adheres them to the inside of the eyeglasses in contact with the wearer's nose bridge. AENBAPs are made of soft plastic, and come in a range of fashion colors. There is an adhesive on the back surface. They are manufactured by filling wells in a mold having a negative impression of the pads with the plastic in its viscous liquid state. After hardening, an adhesive is spread over the surface of the mold, after which a paper similar to wax paper is placed so it can be removed when the adhesive properties are required. Edges of the wells are scored with a cutter for easy separation of the pads (with adhered wax paper), from the mold.

Abstract: A meter interface unit (MIU) for use in sending, via RF or other suitable type of transmission, utility consumption information from a utility meter to a remote location. The MIU includes an antenna electrically coupled to a transmitter device. A microprocessor is operative to initiate reading of usage information from the meter encoder associated with the meter and control transmission of that information at selected times. The microprocessor implements functions to determine which of several known types of meter encoders is present. The meter encoder data is then read and converted to the desired transmission protocol. Power management circuitry is provided to limit application of power to the encoder, except when usage information is being obtained. The power management circuitry may also include step-up circuitry to convert a lower voltage level supplied by a power source to a higher voltage level needed by the encoder.

IPC: A63F9/10
Filed: 2000-04-17
Abstract: An interchangeable game board comprised of multiple puzzle pieces. Each puzzle piece is adorned with at least one geometric object that represents a spot on an overall pathway and an identifying object that classifies that piece within the game. The result of joining these pieces is a game board which provides a continuous, multidirectional pathway by which a player's token can travel around the entire board whilst never encountering a dead end. The puzzle board can be subdivided into nine categories of pieces. Each corner piece being its own category and the other five categories having a multitude of members. Any member can be switched with any other member of the same category and the board and pathway will remain intact. However since no two puzzle pieces in the same category have the same identity, the resulting game board would be unique to that configuration.
