Title: Multi-layered tissue paper web comprising biodegradable chemical softening compositions and binder materials and process for making the same
Inventor: VAN PHAN DEAN
IPC: D21H21/22
Filed: 1994-06-17
Abstract: Multi-layered tissue paper webs comprising biodegradable chemical softener compositions and binder materials are disclosed. The multi-layered tissue webs are useful in the manufacture of soft, absorbent paper products such as facial tissues and/or toilet tissues. The multi-layered tissue paper products contain a biodegradable chemical softening composition, preferably comprising a mixture of an ester-functional quaternary ammonium compound and a polyhydroxy compound. Preferred ester-functional quaternary ammonium compounds include diester dialkyl dimethyl ammonium salts such as diester di(touch hardened)tallow dimethyl ammonium chloride, diester di(hydrogenated)tallow dimethyl ammonium chloride. Preferred polyhydroxy compounds are selected from the group consisting of glycerol, sorbitols, polyglycerols having a weight average molecular weight of from about 150 to about 800, polyoxyethylene glycols and polyoxypropylene glycols having a weight average molecular weight from about 200 to 4,000. The multi-layered tissue paper webs also contain an effective amount of binder materials to control linting and/or to offset the loss in tensile strength, if any, resulting from the use of the chemical softening compositions. The binder materials are selected from the various wet and dry strength additives, and retention aids used in the paper making art. Preferably, the majority of the biodegradable chemical softening compositions will be disposed on the outer layers of the multi-layered tissue paper products where they are most effective. The binder materials alo typically dispersed throughout the multi-layered product to control linting. In other words, the chemical softening compositions and the binder materials can be selectively distributed within the multi-layered tissue paper web to enhance the softness, absorbency, and/or lint resistance of a particular layer or ply.

Abstract: A matrix of pixels of ferroelectric liquid crystal material in which the pixels are defined by areas of overlap between members of a first set of parallel electrodes and members of a second such set which cross the members of the first set and in which each electrode of the first set comprises first and second sub-electrodes connected by a resistive layer is addressed by applying respective strobe signals (22, 24) simultaneously to the sub-electrodes of each electrode (6) of the first set in turn, each time simultaneously applying data signals (27, 42, 56) of variable amplitude and polarity in parallel to the electrodes (8) of the second set. Each strobe signal comprises a pre-pulse (26, 32) and a main pulse (28, 34). The main pulses (28, 34) lie below and above the switching threshold (30) of the material respectively and the pre-pulses (26, 32) are of the same polarity as, and of the opposite polarity to, the corresponding main pulse respectively. The pre-pulses (26, 32) cooperate with the data signals (27, 42, 56) to ensure that, when the material is operated in the inverse mode, switching is assisted where such switching is intended and is inhibited where such switching is not intended,

IPC: G01B3/56
Filed: 1994-12-08
Abstract: A multipurpose rectangular layout Ultra-square (11) which incorporates attributes of a triangular shaped square and carpenters square and is designed for use in conjunction with a tape measure (40). The tape measure (40) is attached in such a way that it forms a right angle to the layout square (11) for measuring distances for framing layout, enabling a user to mark multiple parallel lines in a perpendicular direction at specified distances measured from the end of the tape. The square (11) has indicia (26, 27, 30) in calibrated scales for rafter, angle and linear measurements. The square base (12) extends elongated. A guide (13) is attached at a right angle and perpendicular to the base. The base (12) and guide (13) have edges and notches (20-23, 34) for dimensional marking and placement. Some of these edges are used to significantly reduce the steps required for rafter layout. The square (11) is dimensioned to complement the site of standard material used in construction. Theses dimensions enable the user to mark both the top and bottom plates and the like with multiple parallel lines, to delineate exact location for placement of standard, stringer and sill studs without relocating the square (11). Also, it very quickly locates the reference measuring point and final cut line for all types of rafter cuts. This square (11) may be used from either the left or right direction.

Title: Directory assistance method and apparatus
Inventor: COX PATRICK M
IPC: H04Q7/22
Filed: 1996-09-13
Abstract: A cellular telephone subscriber who wishes directory assistance services is connected in the conventional manner to an operator who identifies a destination telephone number desired by the subscriber. As in the prior art, the operator then initiates a call connecting the subscriber to the destination telephone number.  In a preferred embodiment, the operator locates a desired destination telephone number in a computer database, and can select automatic dialing of the located number.  Further, rather than dropping all further involvement with the call, the preferred embodiment of the present invention continually monitors the connection thereby established for a predetermined DTMF signal issued by the customer, such as that obtained by pressing the "*" button.  If such a signal is detected, the customer is transferred to a directory assistance operator, who can then provide whatever further assistance is needed (e.g. redialing a busy number, or providing further directory assistance). This feature can be disabled, manually or automatically, if the destination number makes its own use of the DTMF signals.

IPC: G06T11/00
Filed: 1996-09-30
Abstract: Apparatus and methods for editing message sequence charts and determining whether a message sequence chart is consistent with a semantic of the system which the message sequence chart represents. As an editor, the apparatus maintains an internal representation of the message sequence chart as a set of processes and events, displays an image of the message sequence chart, and modifies the internal representation in response to modifications of the image by the user. The internal representation can be used to produce further representations of the message sequence chart. One of the representations is an event list which lists send events and receive events in the message sequence chart in a visual order. The event list is used together with a semantic provided by the user of the apparatus to determine whether there is an inconsistency between the message sequence chart and the semantic.

Filed: 1996-10-02
Abstract: A map editing device capable of easily supplementing insufficient information and easily measuring again an object that has changed.  An image, a perspective projection map, a projection center and a projection angle are displayed in superposition.  When a user manually changes the projection center and the projection angle, a perspective projection map after this change is generated and displayed.  When a per-spective projection map capable of obtaining insuffi-cient information is determined, an imaging condition capable of obtaining the insufficient information can be determined based on the projection center and the projection angle at that time.  The insufficient information can be easily supplemented if the arrange-ment is so made as to acquire images conforming with the imaging condition.  The condition necessary for re-measurement can be determined.

Title: Submergent entry nozzle

IPC: B22D41/50
Filed: 1995-04-25
Abstract: A submerged entry nozzle for flowing liquid metal therethrough includes a vertically disposed entrance pipe section having a generally axial symmetry and a first cross-sectional flow area. A transition area having the first cross-sectional flow area with two or more front walls and two or more side walls reduces the thickness of the first cross-sectional area by providing a convergent angle of the front walls and increases the width of the first cross-sectional area by providing a divergent angle of the side walls thereby producing a second cross-sectional area of the transition area which is generally elongated and of planar symmetry. The flow of liquid metal from the transition area is divided into two streams angularly deflected from the vertical in opposite directions.
