Patent EP-0298693-A3 (EP)
IPC: F04D31/00
Filed: 1988-07-05
Abstract: A suspension, such as paper pulp, having a consistency of 
between about 6-20% (i.e. medium consistency) is pumped by a 
pump (10) devoid of a gas removal vacuum system. The pump 
contains a hollow shaft (14) having elongated slots (15, 16) 
and impeller blades (19, 20) are disposed about the shaft 
(14). Connected to the suspension inlet (12) end of the 
shaft is a hollow boat-type propeller (24) which urges 
suspension directly to the impeller blades (19, 20). The 
propeller (24) is disposed in a vessel (30) having an 
enlarged cross-section with respect to the pump housing 
(11), and anti-rotation vanes (33, 34) are placed about the 
propeller in the vessel to prevent rotation of the 
suspension, so that it is fed by the propeller towards the 
blades (18).

Title: Methods of forming passivation films on superconductors
IPC: C01G1/00
Filed: 1989-04-27
Abstract: A fluorocarbon resin passivation film is formed on 
a ceramic superconductor by applying either an ion 
plating method or a dual ion beam sputtering method, 
using a solid as a source material.  
     In the ion plating method, evaporated 
tetrafluoroethylene, for example, is ionised and 
accelerated so as to attain an ion beam energy of 1 to 
10 KeV by which a polytetrafluoroethylene film is 
formed on the ceramic superconductor, and in the dual 
ion beam sputtering method, a sputtered 
tetrafluoroethylene ion beam, for example, forms a 
polytetrafluoroethylene film on the ceramic 
superconductor, assisted by an argon ion beam, for 
example, having ion energy of 1 to 10 KeV.

Abstract: An electrically heatable windshield with a hidden bus bar 
configuration. A border of opaque ceramic material is bonded to an 
interior surface of the transparency about its periphery. Opposing 
electroconductive bus bars are bonded to the ceramic material so that 
the entire inner edge of the bus bar overlays a portion of the

Title: Edge enhancement method and apparatus for dot matrix devices
IPC: G06F3/14
Filed: 1991-09-16
Abstract: An edge enhancement method and apparatus for dot matrix devices are disclosed wherein a group of gradient mask matrices (174) are applied to a current matrix (172), wherein a TBAP (To Be Adjusted Pixel) is surrounded by neighboring pixels, to determine if the TBAP is at a location where a change of brightness occurs. From this matrix operation, a conclusion is derived as to the existence or non-existence of an edge and the direction of the brightness change. The current matrix (172) and a predetermined number of previously evaluated and yet to be evaluated pixels (366, 367) are then compared to a set of reference bit patterns which depict possible segment changes to be corrected. If the result indicates that the TBAP is on an edge of a changing edge segment, a corresponding code will be generated to modify the TBAP to enhance the smoothness of a segment transition. In the case of an electrophotographic printing machine, the specific code will change either the location or the size of the TBAP; whereas in the case of a monochrome screen display, the specific code will change the intensity of the TBAP <IMAGE>

Filed: 1993-06-21
Abstract: The problem of unevenness of bottle temperatures at the entry of slow annealing furnace due to the variation of time periods necessary for respective bottles discharged from an IS bottle manufacturing machine to reach the annealing furnace has been solved by an equalization of said time periods. For this purpose, the bottle discharging order from the IS bottle manufacturing machine is controlled and use is made of two conveyors having different running speeds and/or direction of running. As a result, a precise temperature control in the Hot-End-Coating apparatus provided upstream from the annealing furnace can be carried out owing to the equalized temperatures of bottles entering into the annealing furnace. <IMAGE>
