Title: Method and apparatus for buffing a tire sidewall
Inventor: BROWN ROBERT L
IPC: B24B7/30
Filed: 1992-01-28
Granted: 1996-02-06
Abstract: An apparatus is provided for removing material from the sidewall of a tire.  The apparatus may be used for removing the thin layer of black rubber that normally covers the white letters or white stripe of the sidewall of a newly cured tire, and for buffing the surfaces of such white letters or stripes to give them a smooth finish.  The apparatus may also be used for buffing black portions of a tire sidewall to give those portions a smooth finish.  The apparatus includes a cutting device and a sensor mounted on a moveable carriage.  The sensor measures the distance between the cutting device and a portion of the tire sidewall adjacent to the portion to be buffed.  As the tire rotates while it is being buffed, the carriage moves in response to the sensor's measurement toward or away from the tire sidewall, so that the cutting device removes material at a constant height relative to the adjacent portion of the sidewall.

Title: Mobile telephone device wherein an adder supplies a sum of audio and out-of audio band signals to a compressor circuit
Inventor: KOMODA MOTOYOSHI
IPC: H04W88/02
Filed: 1992-05-12
Granted: 1997-04-22
Abstract: In a mobile telephone device, an adder (17) calculates a sum of (a) an audio signal comprising a talk signal component and a noise component and (b) a generated signal having an out-of audio frequency, as 6 kHz, and a predetermined level and supplies a compressor (21) with the sum as its input signal,  The adder and the compressor give a less variable gain to the audio signal of a lower level range than to that of a higher level range.          Alternatively, the co?pressor alone gives the less-variable gain to the input signal of the lower level range.  A compressed signal is transmitted to a base station as a radio signal and is expanded.          For use in a radio communication system of the type revealed in United States Patent No. 4,025,853, the generated signal can be    given   either by the supervisory audible tone or by the reference tone.

Patent CA-2075911-C (CA)
Title: Bag-in-squeeze-bottle fluid dispenser with means for resisting bag collapse inserted therein
Inventor: SPAHNI MILTON DANIEL
IPC: B05B11/02
Filed: 1991-02-12
Granted: 1996-03-05
Abstract: The invention relates to a collapsible bag in squeeze bottle fluid dispenser.  The problem associated with collapsible bag squeeze bottles is that the collapsible bag collapses upon itself near the discharge opening chocking off fluid flow.  A suitable bag support member is inserted inside the flexible bag (40) to prevent substantial axial movement of the bag (40) in the direction of its discharge orifice (42) and to encourage radial collapse of the bag (40) instead.  The internal bag support member which in a pre-ferred embodiment comprises an extruded plastic helix (60) has an internal fluid passage formed within the coils of the helix. Thus, radial collapse of the flexible bag (40) does not block the passage of fluid remaining in the bag (40) through the discharge orifice (42) in the bag until substantially all of the fluid contained within the bag has been dispensed.

Granted: 1999-01-05
Abstract: A method for interactively selecting and displaying a distribution of all data fields in a selected database. The primary function of the methodology is to allow a user to view the data contained within a selected database in a graphical format. Additionally, the user has the capability of selecting specific sets of data for more detailed display as well as determining the effect of the selection on all remaining data fields which comprise the selected database. The first step in the process is the accessing of the particular database from the host system. Once the selected database has been accessed, a distribution matrix for each field in the selected database is constructed from the data contained within the selected database. The distribution matrix is then graphically displayed on any type of graphical display unit. From this initial graphic display, the user can make various selections for detailed graphical display and study and analyze the data structure and data content of the database.

Abstract: A seating assembly, such as for use in auditorium seating, includes a pair of spaced frame assemblies and a seat and back, each of which is mounted between the frame assemblies. The seat assembly is mounted to the frame assemblies by means of an internal pivoting arrangement providing movement of the seat between an occupied position and an unoccupied, storage position in which the seat is substantially vertical. A biasing arrangement, such as a counterweight; moves the seat toward its storage position. The back is mounted between the frame assemblies by a pivoting back mounting arrangement, providing articulating movement of the back according to the position of the sitter's back. A biasing arrangement, such as a torsion spring, is associated with the back mounting arrangement for moving the back toward a storage position when the seat is unoccupied. The storage position of the back is substantially vertical, to provide a thin depth of approximately 13 inches to the seating assembly when the seat and back are both in their storage positions.
