Title: Transdermal delivery system package
Inventor: CHEN JIA
IPC: A61K9/70
Filed: 1994-06-14
Abstract: This invention is a new packaging system for transder-mal devices (10).  In the preferred embodiment, the devices are adhesive patches mounted on a release liner (12). The liner surface is chosen so that it will not adhere to the adhe-sive on the devices.  Rather, the devices may be peeled off easily by the user.  The release liner (12) is preferably per-forated (20) or scored to permit a portion (22) of the liner below each device to be torn off by the user.  The device may be lifted from the liner by using the torn off portion as a han-dle.  The torn off portion of the liner is itself removed from the device only after the uncovered portion of the device is applied to the user's skin.

Title: Wood coating composition
Inventor: SWARTZ ANDREW JOSEPH
IPC: C08G18/08
Filed: 1996-01-09
Abstract: The invention relates to wood coating composition selected to accentuate the color and the natural grain structure of the underlying surface of a wood article, such as, a furniture or carving. The surface of the article is coated with a waterborne system that includes a copolymer copolymerized from at least one first copolymerizable monomer and at least one second copolymerizable monomer containing a conjugate base of a strong acid. The coating enhances the reddish-yellow hues and suppress the bluish hues and grays.

Title: System and Method for Controlling Play of Multiple Audio Tracks of a Software Carrier
Inventor: OSTROVER LEWIS J
IPC: H04H60/04
Filed: 1994-10-13
Abstract: A system for selectively combining numerous audio tracks recorded on an optical disk (23), including subtracting, by phase inversion, particular tracks from a full mix. Each track might contain a recording of an individual instrument, or a group of instruments. When the disk (23) is played, the player provides the user with menu choices (79) -- which tracks should be played and mixed together. In this way, the user can create his/her own orchestral mix, perhaps omitting an instrument in a "play along" application, or playing one instrument alone to be mimicked for practice purposes. The disk (23) further includes track definitions in multiple languages (79) so that the same disk (23) can be distributed throughout the world, with menu choices (79) being given in a language selected by the user.

A first picture frame element is carried by a first vise, while a second vise is pivoted with respect to the first vise until the angular relationship between the vises is appropriate for the angular relationship intended between the frame elements.  The pivot between the vises may be fixed, and the frame elements joined by known means.  A plurality of the hinged vise pairs may be used simultaneously, with one vise pair associated eachcorner of a non-perpendicular picture frame under construction.  The hinged vise pair of the invention is also adapted to the construction of conventional picture frames by adjusting the vise pair until they are perpendicular.

Patent CA-2191700-A1 (CA)
Inventor: HILLGREN ROBERT
IPC: G05B11/36
Filed: 1995-02-14
Abstract: The present invention relates to a method and a device for executing phase compensation in a control system of a motor-driven vehicle, in which the time derivative for an output signal (y) from a circuit contained in the control system is limited relative to the time derivative for an input signal (u) to the circuit if the time derivative for the input signal (u) exceeds a predetermined value. A difference signal (.epsilon.) is formed between the output signal (y) and a signal (x) present in the circuit, the time derivative of which is not limited in relation to the time derivative for the input signal (u). The difference signal (e) is filtered via an asymptotically stable filter to form a signal (g), which is fed back and added to the input signal (u) of the circuit to form the signal (x). A conventional rate limiter may be used to form the output signal (y) from the signal (x).
