Patent EP-0363109-A2 (EP)
Inventor: PRONOVOST ALLAN DAVID C O EAST
IPC: G01N33/569
Filed: 1989-09-29
Abstract: Antigens extracted from chlamydial or gonococcal organisms are rapidly and ionically bound directly to a polymeric solid support which has cationic groups on its surface. The support is substantially free of any antibody or other biological compound reactive with the antigen. Ionically bound antigen is then contacted with suitable chlamydial or gonococcal antibodies to form a bound immunological complex which is detected in suitable fashion, for example by using a labeled anti-antibody. The entire assay, carried out at room temperature, requires less than 30 minutes and is highly sensitive.

Title: Liquid electrophotographic toners
Inventor: KIDNIE KEVIN M C O MINNESOTA M
IPC: G03G15/01
Filed: 1989-11-24
Abstract: Liquid toners are generally recognized as being capable of providing sharper electrophotographic images, but have been found to provide less than desirable results in multicolor imaging processes. The selection of a unique combination of a) the ratio of conductivities between the toner liquid and the total toner composition, and b) the zeta potential of the toner particles in the carrier liquid have been found to provide unique benefits to the quality of the liquid toned multicolor images.

Abstract: The present invention realizes that the informa­tion necessary to be continuously inputted, outputted in time, namely, the audio and the picture information are inputted, outputted into a file apparatus as the digital data. Conventionally, the continuous inputting, outputting operations of the audio and the picture information and the editing operation such as deletion, insertion and so on could not be made compatible in instantaneousness. But in the present invention, the individual size is continuously stored into the storage media physically, and the input, output of the data and the storage reproduction with the storage media are effected in the non-synchronization, with the size of the input/output buffer, the unit of the in­put/output of the audio and the picture information, and the unit of the edition being the same in size so as to realize the instantaneousness and the continuous input/output operations of the edition.

Abstract: Remoldable panels consisting essentially of a high melting high tenacity thermoplastic polymer and a thermosensitive organic filler are produced by forming a mixture of polymer and filler, extruding the mixture to form a web and calend­ering the web prior to its solidification; the mixture is formed and extruded in a single step by feeding the polymer and the thermosensitive filler into an integral mixing and extruding space that has a feeding end and an extrusion end and comprises:a pair of co-rotating parallel elongated ele­ments each having a length extending between the feeding end and the extrusion end of the integral space; at least three feedingly effective helical extrusion sections mutu­ally distanced along the length of the elements; at least two essentially non-feeding kneading sections each of which is positioned between adjacent extrusion sections; the kneading sections and the extrusion sections of the elements are prov­ided at adjacent positions along their length to form at least two kneading zones and at least three extrusion zones so as to provide one kneading zone between adjacent extrusion zones in the integral space; the polymer is introduced into the inte­gral space in the area of a first extrusion zone located near the feeding end while the thermosensitive filler is introduc­ed in the area of a second extrusion zone situated closer to the extrusion end than the first extrusion zone. A venting means is connected to the extrusion zone nearest the extrusi­on end.

Abstract: A system for selecting from multiple palette lookup tables (LUTs) in a multiple-window system without requiring extra planes in video memory for storing palette information. X and Y position signals representing the current position on the screen are compared with the X and Y minima and maxima of each of the defined windows to determine whether the current position is within one or more windows. If the current position is within two or more windows, the window with the highest priority, as stored in a programmable priority register, is selected, and the lookup table is selected that is assigned to that window by a programmable lookup table register. Successive groups of pixels are processed in parallel to increase the speed of operation.

Abstract: The propellant charge of the propellant-charge module conists of at least two concentric rings (11, 12, 13), of which the outer ring (13) contains propellant-charge grains (21) which supply the maximum quantity of gas per unit time. The burn-up of the propellant charge is initiated by a central ignition (15), so that the rings burn up from the inside outwards. The outer ring (13) burning up last brings about an increased pressure build-up, so that the pressure reduction occurring as a result of the increase in volume of the combustion space is partially compensated. The pressure prevailing in the combustion space is thereby extended in time and the projectile is driven with improved efficiency. <IMAGE>
