Inventor: MIDDLEMISS STEWART N
IPC: C04B35/645
Filed: 2006-05-26
Abstract: Thermally stable ultra-hard compact constructions of this invention comprise an ultra-hard material body that includes a thermally stable region positioned adjacent a surface of the body. The thermally stable region is formed from consolidated materials that are thermally stable at temperatures greater than about 750°C. The thermally stable region can occupy a partial portion of or the entire ultra-hard material body. The ultra-hard material body can comprise a composite of separate ultra-hard material elements that each form different regions of the body, at least one of the regions being thermally stable. The ultra-hard material body is attached to a desired substrate, an intermediate material is interposed between the body and the substrate, and the intermediate material joins the substrate and body together by high pressure/high temperature process.

Abstract: A composition excelling in safety that when locally administered to mammals, can be uniformly dispersed over the mucous tissue; and an ophthalmic solution containing the composition that can stabilize the tear film and can keep the tear film on the surface of the eyeball smoothed. There is provided an ophthalmic solution comprised of an agar-containing composition, the composition comprising as essential components a polysaccharide, especially agar, and water, wherein upon centrifugal separation with 40,000×g by means of a centrifugal separator, the amount of precipitated agar is less than 65 wt.% based on the total amount of agar contained. It is found from results of a corneal surface crook index change test that this ophthalmic solution has an excellent tear film stabilizing activity. Therefore, this agar-containing ophthalmic solution exhibits an effect of sustaining the tear film on the surface of the eyeball in stable form over a prolonged period of time and thus can be used as an artificial tear fluid.

Patent CA-2551550-A1 (CA)
Inventor: HOLM DAVID
IPC: B65G69/00
Filed: 2004-12-17
Abstract: To help hold a (trailer) bed (16) of a truck (12) or trailer steady at a loading dock (14) as the truck is being loaded or unloaded of its cargo, a yieldable vehicle brace (200) exerts a substantial, but limited, reactive force upward against the trailer's rear impact guard (18) to resist the trailer's downward movement. In some embodiments, the brace holds the traile r bed stationary up to a certain load limit and provides the trailer bed with a controlled or dampened descent when the load exceeds that limit. In some cases, the reactive upward force exerted by the brace increases with the downward velocity of the trailer bed. The reactive force can be created by o ne or more pressure relief valves, hydraulic fluid passing through a flow restriction, a brake, a spring, or various combination thereof. Some embodiments of the brace include provisions for accommodating horizontal movement of the rear impact guard.

Inventor: RYAL KIM ANNON
IPC: G06F21/10
Filed: 2005-02-11
Abstract: A readable and writable radio frequency identification (RFID) tag is attached to a physical medium such as a CDROM or DVD. Each time a copy of the medium is created, a variable or count stored in the writable RFID is updated. In cases where the mechanism for reading and writing the RFID is in communication with the device making a copy of the medium, the created copy can have its permitted number of copies set to zero, or other restrictions put in place. Or the device can be prevented from making any copies. In this manner the total number of copies of an original product can be regulated. The RFID can be read or written from a mechanism in a CDROM or DVD player or the read/write mechanism can be in a different device such as in a computer, or in another device.

Title: Switching arrangement for interconnecting electrolytic capacitors
Inventor: FAZAKAS ANDRAS
IPC: H02H9/00
Filed: 2005-02-16
Abstract: Switching arrangement for interconnecting electrolytic capacitors that comprises an electronic switch formed by a semiconductor device and a delay member. The semiconductor device has a control input which is, through an RC-type delay member, connected to a control input (VS) supplying the switching signal. The switching arrangement has a predetermined switching delay. The semiconductor device is a field effect transistor (FT), whose main circuit is coupled through an inductive element (L) supplying a second delay, to the capacitor (C1) to be switched. The inductive element (L) is a conductor (10) of determined length surrounded by a high-frequency ferrite core (11, 12). The delay effected by the RC member ensures only that fraction of the switching delay at which the device is loaded within its permissible load limit and the remaining delay is supplied by the inductive element (L).

Title: Gaming device holding reels with trigger symbols and providing free reel spins
Inventor: GAUSELMANN MICHAEL
IPC: G07F17/34
Filed: 2006-10-18
Abstract: A game variation played on a gaming device displaying reels is disclosed. The game grants awards to the player for certain combinations of symbols. When a player gets one or more special symbols in an initial game, the player gets a free spin of one or more reels while the reels that display the special symbols are held. The player continues to get free spins as long as additional special symbols are displayed after each spin. The player may be granted awards for winning symbols combinations after each spin. In one embodiment, a certain number of special symbols across a payline awards the player a jackpot. In another embodiment, the game is a bonus game where any reels containing special, or trigger, symbols are shifted by one position after each free spin and then held for the next free spin. Only reels that do not display a trigger symbol are spun. The bonus game ends when there are no more trigger symbols displayed. The game may be played on a video gaming machine or a motor-driven reel machine. Various embodiments are described herein.

Title: Heat treatable coated article with diamond-like carbon (dlc) and zirconium in coating
Inventor: VEERASAMY VIJAYEN S
IPC: C03C17/27
Filed: 2005-11-10
Abstract: In certain example embodiments, a coated article includes respective layers including diamond-like carbon (DLC) and zirconium nitride before heat treatment (HT). During HT, the hydrogenated DLC acts as a fuel which upon combustion with oxygen produces carbon dioxide and/or water. The high temperature developed during this combustion heats the zirconium nitride to a temperature(s) well above the heat treating temperature, thereby causing the zirconium nitride to be transformed into a new post-HT layer including zirconium oxide that is scratch resistant and durable. In certain example embodiments, the zirconium nitride and/or zirconium oxide may be doped with F  and/or C.
Patent CA-2588610-A1 (CA)
Inventor: SMITH STEVEN L
IPC: B29C49/00
Filed: 1998-10-01
Abstract: A flexible container (10) is provided for the storage and mixing together of diluents and medicaments. The container incorporates multiple compartments (18, 20, 22) separated by preferentially peeled seals (24, 26) in which the diluents and medicaments are stored. The container is constructed of thermoplastic materials having high oxygen and moisture barrier properties which allows the container to be stored for extended periods of time without degrading the contents. The peelable seals are ruptured by manipulation of the container to thereby mix the contents together for delivery through standard IV arrangement to a patient. The container is fillable with a single component liquid medicament which may be susceptible to sloshing or turbulence. Turbulence is minimized by eliminating the internal gaseous head space by initially forming the head space with a low molecular weight gas such as helium.

Abstract: A blow-molded bottle has a flexible concave perimeter surface extending between an upper peripheral margin projecting outward from the bottle neck and an outwardly protruding ring located above the sidewall upper margin. The flexible concave perimeter surface is specially dimensioned to respond to the presence of a vacuum within the bottle by forming linear segments between the upper peripheral margin and the outwardly protruding ring. The average radius of the vertical mid-point of the concave perimeter surface is generally greater than (3/.pi.) (sin .pi./3) (R1 + R2), and less than (6/.pi.) (sin .pi./6) (R1 + R2), where R1 is the outermost radius of the upper peripheral margin, and R2 is the radius of the outwardly protruding ring. The vertical midpoint radius of the flexible concave perimeter surface measured from the vertical axis can be made to vary by between one and five percent at between three and five positions around the perimeter.
