Inventor: PALMER DONALD J
IPC: C09D11/00
Filed: 1986-12-04
Granted: 1991-09-03
Abstract: Abstract of the Disclosure:        A process for preparing an aqueous-based ink com-position for use in ink-Jet printers is disclosed.  The process comprises (a) forming a solution of a dye having at least one negatively charged functional group per molecule; (b) acidifying the solution; (c) cycling the solution through a reverse osmosis membrane to form a concentrate and a permeate, the concentrate including a cation of the compound associated with at least one functional group on the dye and the permeate including a cation formerly associated with at least one funtional group;  (a) adding water as necessary;  (e) concentrating the dye by reverse osmosis;  and (f) admixing the concentrated aye with at least one glycol etner.  The ph of the ink composition is maintained below about 7.       The formulation of` the final ink composition com-prises: (a) a vehicle of about 5 to 95% water and the balance at least one glycol ether, such as diethylene glycol; (b) a dye, such as Food Black 2, having at least one negatively charged functional group per molecule, present in an amount up to about 10% of the vehicle composition; and (c) a cationic compound selected from the group consisting of alkanol ammonium compounds and cationic amide compounds, present in an amount such that there is at least one molecule of cationic compound for at least one of the negatively charged functional groups on the dye,  the pH of the ink composition being maintained in the acidic region below about 7.       The ink composition prepared by the process of the invention eviaences minimal crusting and reduced evapo-ration loss of water.   The solubility of acid ayes is increased in the acidic medium over that otherwise ob-tainable, due to the presence of the alkanol ammonium compound or cation amide compound.  The ink composition prepared in accordance with the invention  is suitably employed in any of the ink-jet printers commonly in use.

Abstract: Abstract of the Disclosure A method for achieving communication between an injection well and a production well in tar sand deposits.  A cavity is excavated at a point where the injection well is proximate to the production well.  A fluid is injected in the production well at a pressure less than fracture pressure to cause the subterranean formation intermediate the production well and the cavity to collapse and create a highly permeable zone of unconsolidated tar sands, thus forming a communication path between the production well and the injection well.  In a preferred embodiment of the invention several injection vertical wells are used in combination with one associated horizontal production well.  In this embodiment, a hydraulically balanced system may be established by selectively shutting-in the injection wells while maintaining fluid pressure in the production well.  After the communication paths are created, field production operations may begin.  Steam and other fluid may be injected in the injection wells to encourage gravity drainage of bitumen toward the production well.  Bitumen is produced to the surface through the production well via any number of known artificial lift methods.

Abstract: DUAL ACTING HYDRAULIC ACTUATOR  FOR ACTIVE SUSPENSION SYSTEM            Abstract of the Disclosure Active suspension for vehicles with a dual acting hydraulic actuator providing foreshortened overall length for a given amount of stroke.  A conventional suspension unit when designed to give appropriate wheel travel protruded through the hood. The cylinder tube of the actuator of this invention makes use of concentric tubes proportioned to provide the same pressure-force relationship in both directions and to be no larger than the conventional unit.  This actuator also incorporates a trapped air volume that is separate from the oil volumes.  This air volume can be appropriately sized so that an air-spring is created by the moving piston.  The air spring is of approximately the correct load an rate for the vehicle.  This removes the requirement for carrying static vehicle load from the hydraulic portion of the device, which reduces power consumption.  This eliminates the requirement for a coil spring around the actuator to carry these static loads and provides a "limp-home" capability in the event that the hydraulic system becomes damaged.

Title: Ceiling or wall having improved fire resistance and method of installing the same
Inventor: EBERLE GEORGE
IPC: E04B2/00
Filed: 1988-02-29
Granted: 1992-08-11
Abstract: ABSTRACT OF THE DISCLOSURE A ceiling of wall for a partition structure that contains framing members has the usual sheets of wallboard applied side-by-side to the framing members so that seams exist between the edges of adjacent sheets.  Improved fire resistance is derived from runners which extend between the framing members directly behind the seams so as to serve as fire stops and as additional support for the wallboard sheets.  Each runner is at its ends attached to the framing members between which it extends and further consists of several components which slip relative to each other, so that the length of the runner remains constant even though its components experience thermal expansion.          This prevents the runners from bowing and pushing the wallboard sheets away from the framing members in the event of a fire.  The runners further receive and anchor edge fasteners.  Each edge fastener consists of a screw which passes through a seam between two sheets and threads into the runner behind that seam and also a disk which the screw draws up against the exposed surfaces of the sheets on each side of the seam.  The disks, while supporting the sheets, allow the sheets to shrink without destroying their structural integrity in the region of support.  To in stall the ceiling or other wall surface, the first sheet of wallboard is attached to the framing members; then the runners are installed by fitting them partially under the first sheet and securing them to the framing members; next the second sheet is attached to the framing members; there-after the edge fasteners are installed along the seam; and finally the seam is covered with joint cement and tape.      The runners have tabs which cause them to be located against the edge of the first sheet so as to be centered with respect to the seam when the second sheet is attached to the framing members.                           - 1a -

Abstract: (57)Abstract An arrangement in a water craft is de-scribed for collecting oil present on the surface of water, especially among blocks of ice. The arrangement comprises a bow part (2) the flat lower surface (3) of which is gently sloping and equipped with inlet openings for contaminated water. When the craft is moving forwards, blocks of ice are pressed under the surface (3) and at the same time rinsed. The rinsing can be promoted by means of strong water jets. In order to achieve the optimal operating conditions in each particular case, the bow part (2) has been arranged to be a part separate from the hull (1) of the craft and capable of being raised and lowered in relation to the hull, which also enables this bow part to be coupled to an already existing craft of suitable size. The arrangement comprises, in a known manner, separating means (9) for separating oil from the inflowing water, as well as means for removing the cleaned water, all of which are preferably fitted in the separate bow part (2). The recovered oil is conveyed continuously from the bow part (2) to a tank located, for example in the craft.     Figure 1
