Title: Tape path having implicit squeeze bearing
Inventor: COMEAUX WAYNE T
IPC: G11B23/04
Filed: 1992-03-02
Granted: 1995-02-28
Abstract: The invention is a tape path having an implicit squeeze bearing.  In such a tape path, one end of the tape is wound upon a first reel,  the tape extends around one or more guides, briefly comes into close proximity with itself at the outer wrap of the tape wound upon the first reel, and is wound upon a second reel.  By coming within close proximity with itself,  the tape forms  an implicit  squeeze bearing which   damps   tape   tension   variation,   inhibits   the transmission of vibrations from one reel to the other, and eliminates  the  entrapment  of  entrained  air  without  any additional rollers or other components.  The tape path is suitable for use in a peripheral storage device, such as a magnetic tape drive,  and is compatible with a variety of tape cartridge configurations.

Title: Radio receiver capable of suppressing a frequency drift in an intermediate frequency
Inventor: KOJIMA TATSURU
IPC: H04B1/40
Filed: 1992-06-26
Granted: 1999-01-26
Abstract: A radio receiver for receiving a radio signal includes a counter which determines an eventual intermediate frequency of an amplified signal based on a reference signal as a count datum. A frequency controller controls a reference frequency of the reference signal according to the count datum. A reference oscillator is controlled by the frequency controller to produce the reference signal. When receiving a radio signal by a double superheterodyne method, the radio receiver gives the eventual intermediate frequency to the amplified signal. In the amplified signal, the frequency controller suppresses an eventual frequency drift which results from frequency drifts of a first local oscillation and a second local oscillation. The radio receiver may also be a single superheterodyne receiver.

Title: Power transmitting system of four-wheel drive vehicle
Inventor: HAMADA TETSUROU
IPC: B60K17/34
Filed: 1992-07-03
Granted: 1996-04-16
Abstract: A power transmitting system of a four-wheel drive vehicle having primary driven wheels driven directly by a prime mover, and subsidiary driven wheels driven through a hydraulic clutch.  The power transmitting system comprises a first hydraulic pump driven in operative association with the pri-mary driven wheels and a second hydraulic pump driven in operative association with the subsidiary driven wheels.  Each hydraulic pump has a pair of ports which serve as an intake and a discharge with the functions of such ports being reversed between forward and backward movement of the vehicle.          A first oil passage connects the intake port of one pump with the discharge of the other pump and a second oil passage con-nects the discharge of the one pump with the intake of the other pump.  Third and fourth oil passages connect the first and second oil passages, respectively, with a working hydrau-lic pressure chamber in the hydraulic clutch.  A one-way valve is provided in each of the third and fourth oil passages for permitting only a flow of oil toward the working hydraulic pressure chamber.  The reversal of vehicle movement and direction of oil discharged from each of the hydraulic pumps provided in the power transmitting system of the four-wheel drive vehicle is compensated for by a simple structure of oil passages and one-way valves.

Title: Incineration of waste gas containing toxic or other fumes in the form of liquid droplets
Inventor: GOSSELIN GERARD
IPC: B01D53/34
Filed: 1992-07-21
Granted: 1999-11-02
Abstract: A method for treating waste gases containing toxic or odorous vapors in the form of a mist of liquid droplets using a regenerative incinerator of a known structure to do so. In this method, the waste gases to be treated are passed through a mist separator device installed in the waste gas supply duct of the incinerator in order to capture and remove a sizeable portion or all of the supplied mist thereby reducing or eliminating the amount deposited in the incinerator. There is also proposed to raise the temperature of the incinerators sufficiently to cause all the liquid condensate to be evaporated immediately upon their admission into the working parts of the system. There is further proposed to effect the evaporation of the liquids deposited in the surfaces of the equipment and packing by purging the beds of packing at each cycle, with a gas stream heated to a temperature sufficient to cause the evaporation of all the liquid deposits. There is also proposed to effect the removal of solid deposits in the regenerators by a periodic combustion cycle.

Abstract: A paint roller frame and cage assembly mounted for rotation on a shaft portion of the roller frame. The cage assembly includes a plurality of circumferentially spaced, axially extending support bars joined together by a plurality of ribs providing an annular support for uniformly supporting a roller cover thereon. At the inboard end of the support bars is an annular flange having an outer diameter less than the outer diameter of the annular support. Mounted on the annular flange is a retaining spring including a Belleville type spring washer having circumferentially spaced apart spring fingers extending radially and axially outwardly from the outer periphery of the washer for fractionally retaining the roller cover on the cage assembly. The Belleville type spring washer is retained on the annular flange by an end cap having a first annular sleeve telescopingly received over the annular flange. A radial shoulder on the end cap acts as a stop for locating the roller cover on the cage assembly when the roller cover is fully inserted thereon. The end cap also includes a second annular sleeve radially outwardly spaced from the first sleeve having an outer diameter substantially corresponding to the outer diameter of the annular support to provide a continuation of the annular support for supporting the roller cover up against the radial shoulder on the end cap, but with a clearance space between the end of the second annular sleeve and adjacent ends of the support bars for receipt of the retaining spring fingers therein.
