Title: Electrophoretic display with single character erasure
Inventor: DISANTO FRANK J
IPC: G02F1/16756
Filed: 1992-08-21
Abstract: A triode-type electrophoretic display (10) includes a pair of substantially identical glass faceplates (12, 14) sealed against a peripheral sealing wall (16) to form a fluid-tight envelope for containing an electrophoretic fluid. A first faceplate (12) bears the anode which is composed of a plurality of elongated substanitially parallel vertical conductor members (18) disposed within a first plane and a plurality of elongated substantially parallel vertical conductor member(20). The horizontal and vertical members are insulated from each other by interstitial insulator strips underlying the vertical members and by a SiO2 layer. The vertical and horizontal members are slotted and grouped into: groups so that the area of the intersection of a vertical group and a horizontal group approximates that of a single character. The cathode and grid are formed on the other faceplate in essentially the same manner as the composite anode. By placing the proper voltages on the horizontal and vertical elements of the anode, selective characters  may be erased from the display.

Title: Laterally adjustable cantilever shelf for a refrigerator
Inventor: DASHER JAMES F
IPC: A47B57/40
Filed: 1994-02-22
Abstract: ABSTRACT A laterally adjustable cantilever shelf system for a refrigerator/freezer includes a formed metal bracket which defines a continuous channel. The bracket includes hooks to engage into slots in shelf standards in a refrigerated compartment. This enables the bracket to be placed at any select vertical position within the compartment. A shelf accessory includes sheet metal side arms each having a hook at the top rear that mates with a channel in the bracket to retain the shelf. Sufficient clearance is provided between the shelf side arm and the channel to allow the shelf to be moved by slightly lifting the front of the shelf to relieve the pressure between the top hook and the channel and applying lateral pressure. An additional hook at the bottom of the side arm interferes with the channel when the front of the shelf is lifted to prevent the shelf from becoming accidentally dislodged. The storage accessory is removed by raising the rear of the shelf, tipping the bottom hook of the side arm out of the channel and then tipping the top hook out of the channel.

Title: Structural curtainwall system and components therefor
Inventor: NEUDORF PETER
IPC: E06B3/54
Filed: 1994-03-03
Abstract: Abstract It is known in structural curtainwall systems to have a series of rafters and purlins supporting glass panes.  It known also to provide drainage panels in the supporting elements to drain away any water which seeps past the external surfaces of the glass panes.  In this invention, separate panels are formed comprising purlins and sub-frame members and supporting glass panes.  These panels will be formed off-site in a factory.  The sub-frames of the panels are received directly into channels in the rafters thus enhancing the resistance of the system to leakage particularly where the panels intersect the rafters.  The joint between adjacent panels spanning the same pair of rafters is sealed by providing tongue members on the purlins which are resiliently deformable.  The biasing of the tongue members provides a seal between adjacent panels.  Furthermore, the tongue members form drainage channels to drain water into the drainage channels of the rafters.

Title: Method and apparatus for automation of directory assistance using speech recognition
Inventor: LENNIG MATTHEW
IPC: H04M3/42
Filed: 1994-03-15
Abstract: In a telecommunications system, automatic directory assistance uses a voice processing unit comprising a lexicon of lexemes and data representing a predetermined relationship between each lexeme and calling numbers in a locality served by the automated directory assistance apparatus. The voice processing unit issues messages to a caller making a directory assistance call to prompt the caller to utter a required one of said lexemes. The unit detects the calling number originating a directory assistance call and, responsive to the calling number and the relationship data computes a probability index representing the likelihood of a lexeme being the subject of the directory assistance call. The unit employs a speech recognizer to recognize, on the basis of the acoustics of the caller's utterance and the probability index, a lexeme corresponding to that uttered by the caller.

Filed: 1994-05-30
Abstract: A user interface technigue operates in the environment of a processor-controlled machine for executing a program that operates on a set of underlying data and displays a visible representation thereof.  The system further provides a visual depiction of a set of tools.  The tools include click-through tools that can be combined with other tools (including other click-througb tools) to provide composite tools.  A click-through tool includes a generally transparent delineated active area that is movable so that it can be placed over a desired portion of the visible representation. When the user interacts with the visible representation through the active area, the action takes on an attribute of the particular click-through tool. A click-through tool can be superimposed on another click-through tool, whereupon an action taken through the two click-through tools onto the visible representation takes on attributes of both tools.

Patent CA-2134747-A1 (CA)
Inventor: FRADENBURGH EVAN A
IPC: B64C27/46
Filed: 1993-05-26
Abstract: A variable diameter rotor (3) for a flit rotor aircraft (1) has an inboard section (11) having a linear twist from a root end (12) to an outboard end (13) thereof; and an outboard section (14) telescoped over the inboard section (11) which additionally has a linear twist from a root end (17) to an outboard end (14) thereof. The outboard section (14) is disposed at an offset of about 4 to 15° relative to the inboard section, (11) to provide a stepwise change in twist angle when in the extended condition, such that the rotor when operated in the helicopter mode, can be operated at high blade pitch angles without premature stalling along the in-board airfoil surfaces. This allows efficient operation at high thrust coefficient/solidarity ratios. Optionally, the trailing edge of the outboard section is rotated along the aft 34 % of chord of the airfoil section to provide an equivalent twist increase in the off-set at the transition between the blade sections. When in the forward flight cruise made, the inboard equivalent twist increment allows operation of the inboard airfoil sections at higher pitch angles to reduce negative lift regions and increase cruise propulsion efficiency.

Title: Improvements in general purpose cleaning compositions
Inventor: FRUSI ANDREA BRUNO
IPC: C11D1/04
Filed: 1993-10-09
Abstract: Ideal household cleaning compositions should form a relatively stable foam on application to a surface and rapidly defoam when rinsed from the surface. The present invention subsists in an aqueous cleaning composition comprising: (a) a surfactant system comprising an anionic surfactant other than an alkali metal salt of a fatty acid, (b) C10-C18 monocarboxylic fatty acid, (c) a semi-polar solvent, (d) a polycarboxylic acid, and (e) a base, said composition having a pH of less than 6. It is believed that the C10-18 fatty acids have a foam boosting effect which improves 'cling' of the foam to sloping or vertical surfaces. When the compositions are diluted during rinsing the fatty acid and the solvent form an antifoam system which defoams the composition.
