Abstract: Abstract of the Disclosure At the cleaning station of a photocopier, a cleaning system including a wetted cleaning roller of resilient closed-cell material and a sealing roller of resilient non-cellular material past which cleaning and sealing rollers the imaging surface is sequentially moved.  The cleaning roller contacts the imaging surface and is so driven that its surface adjacent to the imaging surface moves in a direction opposite thereto to provide a scrubbing action.  The sealing roller contacts the imaging surface and is so driven that its surface adjacent to the imaging surface moves in the same direction as and at the same speed as the imaging surface to provide a dynamic seal.  Preferably, the sealing roller has a surface smoothness of between 2 and 10 microinches.  The sealing roller may be formed by casting polyurethane in a glass tube to form an extremely smooth outer surface which provides a highly effective seal with the imaging surface against the flow of cleaning liquid.  In a preferred embodiment, the sealing roller engages the cleaning roller so as to be cleaned of any adhering toner particles by the action of the cleaning roller.

Abstract: ABSTRACT OF THE DISCLOSURE         The present invention provides a process for separating the organic constituents of "black-liquor" that is formed under chemical pulping of cellulose products.  This black-liquor is heated with CO and/or H2 under pressure which results in the conversion of said organic constituents into a water-insoluble liquid or oil which can be separated from the water phase by usual means.  Said conversion can be effected in one or more separate stages, the conversion conditions being different from stage to stage.

Abstract: ABSTRACT OF THE DISCLOSURE The method of selectively depositing a metal pattern on the surface of a laminar film comprising a dielectric substrate having a co-extensive metallic layer and a ceramic overlayer. A desired metallic pattern may be formed on the surface of the film by applying a releaseable mask in those regions of the film surface where plating of the surface is not desired, catalyzing the unmasked regions of the film surface, removing the mask from the film surface and thereafter immersing the film in an electroless plating bath whereby only the catalyzed regions are plated with the electroless metal of the bath. The preferred film has gold intermediate layer upon which elec-troless nickel or copper pattern plating is accomplished.

Abstract: 18. ORGANIZATION FOR DYNAMIC  RANDOM ACCESS MEMORY            Abstract of the Disclosure An MOS dynamic random access memory (RAM) includes an array of memory cells arranged in rows and columns.  The array is divided into two or more sub-arrays (1001, 1002). In an operating cycle where a cell is being accessed for reading and/or writing, only the sub-array containing the accessed cell is fully selected while the other sub-arrays are partially selected.  A fully selected sub-array is one in which both a row and a column are selected, whereas in a partially selected sub-array, only a row is selected.  In the partially selected sub-array where only refreshing of the cells in the selected row takes place, the column (1003, 1004) decoders and drivers remain inactive throughout the memory cycle.

Abstract: CONTACT SPRING ARRANGEMENT FOR AN ELECTROMAGNETIC RELAY      Abstract of the Disclosure A contact spring arrangement for an electromagnetic relay includes a contact spring forming at least one movable contact for cooperation with a fixed contact, and an actu-ator which embraces the contact spring and has a first por-tion for moving the movable contact towards the fixed con-tact, thereby closing the contact couple, and a second por-tion for withdrawing the movable contact from the fixed con-tact, thereby opening the contact couple. The actuator is so shaped that the distance between the location at which the first actuator portion engages the contact spring and the contacting location of the contact couple is greater than the distance between the location at which the second actuator portion engages the contact spring and the said contacting location. As a result, in the closed condition of the contact pair, the first actuator portion will be able to bend the contact spring to provide sufficient resilient contact force, whereas, in the opening of the contact couple, the second actuator portion will entrain the contact spring with very little resiliency of the contact spring, thus tending to tear the contact couple apart even in case stick-ing or welding should have occurred between the fixed and movable contacts.

Abstract: ABSTRACT OF THE DISCLOSURE         A method and apparatus for electromagnetic casting of castable materials including, but not restricted to, metals and alloys and silicon or other similar semi-metals, metall-oids, and semi-conductors ingots of desired shape having portions of small radius of curvature.  A modified shield is provided which provides for a reduction of the electromagnetic field intensity at the corners of the forming ingot by in-creasing local screening of the field at the corners.  In-creased local screening at the corners is achieved by locally increasing shield depth, by providing for deeper displacement of the shield, by changing the shield section, or by changing the shield orientation.  Also discussed is a modified in-ductor which is shaped so as to be located at a greater dis-tance from the portions of small radius of curvature of the ingots than form portions of the ingots adjacent to the por-tions of small radius of curvature.  The modified shield may be combined with the modified inductor and/or with a coolant manifold to simultaneously modify and control coolant applic-ation elevation such that the elevation is a minimum at the corners of the ingot.

Abstract: 6724     INVENTOR: MAX DEGEN CAN         INVENTION: APPARATUS FOR AN AIRCRAFT FOR DROPPING OBJECTS     ABSTRACT OF THE DISCLOSURE   To drop objects from a container or receptacle mounted at an aircraft there is beneficially employed a pressure head. For this purpose the object mounted internally of the container upon guide rails is impinged at its front end by the flight-pressure head of the aircraft, so that it is ejected from the tail end of the container. For rapidly realising the necessary safety distance between the aircraft and the dropped object at the tail end of the container there is deflected a flow onto the departing object, so that a pressure pulse is applied to the object and it is accelerated. The invention is particularly suitable for accurately laying a multiplicity of objects at surface-like or areal targets i.e. upon a given terrain. Its use is contemplated for both civilian applications, such as dropping life saving and supporting equipment and so forth, and military applications, such as for dropping bombs, mines and other ordinance. The apparatus is extremely simple and functionally reliable. The only movable auxiliary means needed is a controllable bolt or equivalent structure within a blocking device for the release of the object.
