Title: Well pump tubing scrapers
Inventor: BERTAGNOLLI JOHN
IPC: E21B17/10
Filed: 1994-08-05
Abstract: A well pump sucker rod scraper arrangement that includes a sucker rod, scrapers fixed to said rod and a scraper at spaced apart positions movably mounted on said rod, between adjacent pairs of the fixed scrapers.  The movable and fixed scrapers each have surfaces at respective opposite ends thereof and an outer fluted surface.  The fluted surface is defined by spaced apart ribs and the ribs on the movable scraper are angularly disposed relative to the longitudinal axis of the rod.          The movable scraper has a slot lengthwise thereof with a throat portion whose width is narrower than the diameter of the rod and through which the rod passes when pressing such movable scraper onto the rod. A lug on the fixed scrapers project therefrom in a direction toward an adjacent movable scraper and the lugs are so positioned so as to project into said slot of a movable scraper associated therewith as the latter approaches the fixed scraper and prior to engagement of the abutting planar end surfaces on the respective scrapers.
Patent CA-2130490-A1 (CA)
Inventor: RADU GEORGES
IPC: C09D9/04
Filed: 1994-08-19
Abstract: Disclosed is a synergistic paint removing composition comprising a particular selection of a plurality of known solvents in very specific proportions, namely: from 20 to 45% of aromatic hydrocarbons; from 15 to 30% of dimethylformamide; from 15 to 25% of N-methyl pyrrolidone; from 5 to 15 % of a water-immiscible compound selected from the group consisting of terpene derivatives, oleoresins and mixtures thereof; and from 0.5 to 4% of at least one wetting agent, all the above percentages being expressed by weight.      This composition is partially miscible in water even though some of its constituents are not water miscible, thereby making the composition easy to wash and thus preventing oily film to be left on the treated substrate. The composition according to the invention is normally in a liquid form. If desired, for some applications, a thickening agent can be added thereto to "convert" it to a gel.

Title: Encapsulated magnetic particles, pigments and carbon black, compositions and methods related thereto
Inventor: ELWAKIL HAMDY A
IPC: H01F41/16
Filed: 1993-05-07
Abstract: Encapsulated particles, such as magnetic particles, colored pigments, or carbon black, with high chemical affinity for ink vehicles. The encapsulated particles are suitable for printing inks, as well as for magnetic recording systems, such as audio and video tapes and magnetic storage disks. The encapsulated particles comprise particles having a coating on their surface formed from an ionomer or an oil, such as soya oil, or a mixture of ionomers and oil, and optionally a thixotropic agent, and/or a binder resin. The method for making such encapsulated particles avoids the use of volatile organic solvents and provides printing inks and coating compositions which also avoid the use of volatile organic solvents. Inks may be readily formulated, without the need for any complicated and expensive flushing process, by simply dispersing the encapsulated coloured pigment or carbon black in the desired vehicle.

The closure unit has a region madeof outlet material (A) and a region made of closure material (B), which two regions are joined together by a flow seam.  The flow seam extends in such a waythrough the closure unit that at least parts of the sealing face on the side of the outlet are made of outlet material and that at least parts of the sealing face on the side of the closure are made of closure material.  The closure unit is manufactured by way of a simultaneous casting method.   The pairing of materials and the casting parameters of the two simultaneous casting processes are such that the two materials meet at the position provided for the flow seam and form a flow seam (31).  The position and shape of the flow seam can also be defined by movable hollow mould parts (pushing devices).

Title: Oxidant injection for improved controlled oxidation
Inventor: VUONG DINH-CUONG
IPC: F27D3/00
Filed: 1995-06-28
Abstract: A selective deslagging operation is conducted in a partial oxidation reactor wherein a first predetermined portion of the reactor is selectively deslagged by derivatization while limiting derivatizing slag conditions in a second predetermined portion of the reactor. Selective deslagging can be accomplished by controlled oxidation conditions in the reactor that vary from one predetermined portion of the reactor to another. Thus, the slag present in one predetermined portion is derivatized and fluidized for removal from the reactor at a faster rate than the slag present in another portion of the reactor, which is not derivatized or is subjected to more limited derivatizing slag conditions. Derivatized slag can be differentiated from non-derivatized slag that does not flow or more limited derivatized slag that has a lower mass flow rate then the derivatized slag at conditions of controlled oxidation. The derivatized slag can then be selectively removed because it has attained a lower fluidizing temperature.

Title: Snow removal device
Inventor: PHILLIPS KENT D
IPC: E04D13/10
Filed: 1995-10-02
Abstract: A snow removal device permits a user to subdivide and then pull down sections of snow accumulated on a roof or other surface. An elongated handle supports an oppositely disposed blade and cutter, the cutter preferably having a taut wire between side struts attached to a top edge of the blade. The user draws the cutter through a section of snow, subdividing a rectangular slab of snow from the accumulated snow, then flips the device over and removes the slab with the blade. The cutter is generally perpendicular to the handle and the blade is inclined to lift the snow in the pulling direction.  The cutter can be height adjustable and wheeled at the side struts, with the side struts shaped and coated for minimal friction. The handle can be length adjustable, e.g., by telescoping, and angularly adjustable or compactly collapsible via an articulation having complementary splines and groove for setting an articulation angle.

Abstract: Whether to encode a present video block of an incoming video frame, i.e. intra code, or whether to encode the difference between the present video block of the incoming frame and a best match video block from a previously stored video frame, i.e. non-intra code, is determined in a video compression system 100. First the present video block is divided into a predetermined number of sub blocks 301. Then an average pixel value is calculated for each sub block 302 and used along with the individual pixel values of the sub block to determine sub block deviations 303. The sub block deviations are used to compute a present video block deviation 303. The present video block deviation is then compared with an error deviation 306 that is calculated based upon the present video block pixel values and the best match video block pixel values 305. If the comparison is favorable, then the difference between the present video block and the best match video block are encoded. If the comparison is unfavorable, then the present video block is encoded.
