Title: A device for coating moving webs of paper or board
Inventor: KUSTERMANN MARTIN
IPC: D21H23/52
Filed: 1993-05-11
Abstract: Abstract of the Disclosure The invention relates to a coating device for coating moving webs of material, more particularly webs of paper or board, comprising a belt or hose (7), which is trained about the curved guide surface of a beam- or rod-like support member (1) and a drive roll (6), a cooperating roll (C) carrying the web, a coating gap (9) being defined between the cooperating roll (C) and the hose (7) for the application of the coating material to the web or the roll, a support beam (3), which extends in parallelism to the roll and the drive roll (6), for supporting the support member (1), and between the same a pressure hose (4) for the transmission of the support forces.   The invention is characterized in that the support member (1) possesses a rib- or rail-like extension in its part remote from the curved guide surface at the gap (9), on which there acts a further pressure hose (5 and 5') arranged between a corresponding support surface on the support beam (3) and the extension of the support member (1), essentially in a direction which is transverse in relation to the direction of action of the first pressure hose (4 and 4'), the first pressure hose (4 and 4') being arranged essentially at the free end of the extension (2 and 2') of the support member (1 and 1').
Patent CA-2114763-A1 (CA)
Title: Vent for shielded enclosures
Inventor: CURRAN WILLIAM E
IPC: H05K9/00
Filed: 1994-02-02
Abstract: VENT FOR SHIELDED ENCLOSURES  Abstract of the Disclosure A shielding vent for an electromagnetic inter-ference shielded enclosure having an electrically con-ducting wall shield includes a mounting plate or flange through which extends a vent pipe with an internal septum plate or divider extending axially along at least a portion of the inner length of the vent pipe.  The mounting flange is secured to a wall of the shielded enclosure over an opening in the wall and to the wall shield to insure that the integrity of the shielding for the enclosure is maintained.  With the mounting flange so mounted on the wall of the enclosure, the vent pipe extends through the opening in the wall of the enclosure and provides fluid communication between an internal region of the enclosure and a region external of the enclosure.  The septum plate has a cross section in the shape of a cross so that at least a portion of the length of the cylindrically shaped vent pipe is sub-divided into four parallel, axially extending equal fluid flow sections.  These fluid flow sections are suf-ficiently large in cross sectional area that they pro-vide a minimum of resistance to fluid flowing through the vent pipe.  By using the cross-shaped septum plate in the vent pipe, the vent pipe can be made signifi-cantly shorter in length than previously used vent pipes of similar diameter, yet the vent affords an adequate degree of EMI shielding.

Title: Vehicle shape determination system
Inventor: COACHWORTH SIMON
IPC: G01S11/14
Filed: 1992-08-14
Abstract: A vehicle measure system involves an array of microphones (18) and a spark emitter (24, 46) mounted on a vehicle. Spark ing produces sound bursts which travels to the microphones (18). From detection of transmission times, the position of the emitter (24. 46) is found. Sound velocities arc determined in various directions to ensure the air is homogeneous, else corrections for Sound speed variations are applied or data is rejected. Position data determined from various microphones (18) are compared to ensure repeated measurement accuracy. The apparatus includes simple circuitry with fewer received signal processing channels than microphones (18) and intelligent selection of active microphones in consequence. An emitter can be connected to the upper vehicle body via a bent coupler (78), which can pass around a wing for example. This allows the system, which is ground based, to be used for measurements of the upper vehicle body. The positions of microphones (18) are determined precisely before use of the system, using a calibration jig (124). Errors in microphone positioning are then corrected for in the measurements.

Title: Methods and apparatus for winding armatures with improved balance
Inventor: CARDINI GIUSEPPE
IPC: H02K15/16
Filed: 1994-03-14
Abstract: Abstract of the Disclosure The balance of rotors for dynamo-electric machines (e.g., electric motor armatures), which are wound with two diametrically opposite, simultaneously applied coils of wire, is improved by ensuring that wire is fed to both coils in substantially similar quantities.  This can be accomplished by monitoring the consumption of each wire as it is fed to its respective coil, and adjusting the tension with which at least one wire is fed to its coil to substantially equalize the wire consumptions.  Alternatively, the tension at which both wires are fed to the coils is monitored, and the tension of at least one wire is adjusted to equalize the tension of the two wires.

Title: Polymerization of functionalized monomers with ziegler-natta catalysts
Inventor: WAYMOUTH ROBERT M
IPC: C08F4/6592
Filed: 1993-11-17
Abstract: Catalysts derived from the reaction of Cp*2ZrMe2 with B(C6F5)3 or [N,N-dimethylanilinium][B(C6F5)4] (denoted as [Cp*2ZrMe]+X-, Cp* = pentamethylcyclopentadienyl, X =  B(C6F5)4 or CH3B(C6F5)3) are active for the homopolymerization of functionalized dienes and alpha-olefins such as 4-TMSO-1,6-heptadiene (TMSO = trimethylsiloxy), 5-TBDMSO-1-pentene (TBDMSO  = tert-butyldimethylsiloxy), 5-N,N-diisopropylamino-1-pentene, 5-diphenylphosphino-1-pentene and N-(1-penten-4-yl)carbazole.  Other metallocene catalysts such as [rac-(EBTHI)ZrMe]+X- and [EBIZrMe2]+X- (EBTHI =  ethylene-1,2-bis(n5-4,5,6,7-tetrahydro-1-indenyl, EBI =  ethylene-1,2-bis(1-indenyl)) are active polymerization catalysts for the polymerization of functionalized olefins although they are more easily poisoned by silyl ethers; [rac-(EBTHI)ZrMe]+X- catalysts polymerize 4-TBDMSO-1,6-heptadiene and 5-N,N-diisopropylamino-1-pentene. A variety of other silyl ethers were polymerized. Preliminary 13C NMR analyses of polymers obtained from the functionalized alpha-olefins with [(EBTHI)ZrMe]+X- catalysts are consistent with highly isotactic microstructures. Predominantly syndiotactic polymers are produced at -25 ·C in the presence of [Cp*2ZrMe]+X- catalysts which is consistent with chain end control. Treatment of the polysilylethers with HCl affords novel polyalcohols. Addition of HCl to poly(5-N,N-diisopropylamino-1-pentene) yields the corresponding polyelectrolyte. Metallocene/methylaluminoxane catalysts are active for the polymerization of alpha-olefins containing silyl ether groups.
