Title: A method and apparatus for separating a frozen deposit from a substrate; Aircraft de-icing.
Inventor: MORGAN PETER CHARLES
IPC: B64D15/12
Filed: 1991-01-29
Abstract: A method and apparatus for separating a deposit (1) of frozen, electrically conductive, material such as ice from a substrate surface such as the wing (8) of an aircraft (5) (Fig 4) involves the application of a layer (3) of at least one electrically conductive polymer to the surface (2) or dispersion of at least one electrically conductive polymer in the substrate of the surface (2). The deposit (1) forms on the surface of the substrate containing the polymer or on the polymer layer (3). The deposit is separated therefrom by varying the surface energy of the polymer dispersion or layer (3) between a first surface energy value at which formation of the deposit (1) occurs and a second surface energy value at which separation of at least part of the deposit (1) from the polymer layer (3) or polymer containing substrate surface (2) occurs. Copper electrodes (4) on an insulating base, e.g. alumina (4a) are provided. Substrate (2) may be metal, glass, or plastics. The polymer (3) may be polyaniline or polybithiothene or polyfluorosulphonic acid.

Title: A casting process for producing nodular iron castings
Inventor: CAVANAGH JOSEPH
IPC: B22D1/00
Filed: 1991-05-16
Abstract: Additives containing magnesium are mixed with molten flake iron in a ladle (40) to produce a nodular iron melt which is delivered to moulds to form the castings. The additives comprise a magnesium additive (55) of magnesium ferro-silicon alloy introduced first to the ladle (40) and overlaid with a protective cap (56) of ferro-silicon additive. The additives (55, 56) are placed in an additives compartment (51) formed on one side of a dam (50) in the ladle (40). Flake iron melt is delivered to a melt compartment (52) on the other side of the dam (50) eventually overflowing the dam (50) into the additives compartment (51) to react with the additives (55, 56). The arrangement of the dam (50) and the ferro-silicon cap (56) allows a more controlled mixing of the flake iron melt and magnesium additive. <IMAGE>

Abstract: A method for the separation of a less dense liquid from a body of a more dense liquid on which it is floating, especially for the separation of oil floating on water, which comprises passing a column of liquid at high velocity substantially vertically from within the body of liquid through the surface thereof thereby to entrain the less dense liquid and carry it away from the surface, and collecting the mixture of less dense liquid and other liquid(s) thereby produced. Apparatus for use in the invention comprises means for generating a high velocity column of carrier liquid, means for directing the column upwardly through the body of liquid and the floating layer of less dense liquid to entrain the less dense liquid in a surface layer of the column and means for directing the carrier liquid and entrained less dense liquid to a collector device. The directing means may comprise, for example, a spreader device with an outwardly and upwardly flared portion which diverts the liquid mixture to an annular collector or it may comprise a mushroom-shaped surface for directing the liquid mixture into a collector surrounding the support rod.

Patent GB-2258933-A (GB)
Title: Cache affinity scheduler
Inventor: VALENCIA ANDREW J
IPC: G06F9/50
Filed: 1992-08-19
Abstract: A computing system 50 includes N computing engines having N cache memories connected by a system bus 12. The computing system includes a global run queue (fig 5 not shown), an FPA global run queue, and N affinity run queues, each associated with one computing engine. When a process first becomes runnable, it is typically attached to one of the global run queues. A scheduler allocates engines to processes and schedules the processes to run on the basis of priority and engine availability. Each time a process becomes runnable, the scheduler estimates the remaining cache context for the process in the cache of the engine. The process is enqueued to the affinity run queue of the engine when the estimated cache context of the process is sufficiently high, and is enqueued onto the global run queue when the cache context is sufficiently low. The procedure, therefore, increases computing system performance and reduces bus traffic because processes will run on engines having sufficient cache affinity e.g. engines on which the process was previously running, or will run on the best available engine when there is insufficient cache context. <IMAGE>

Patent GB-938535-A (GB)
IPC: G03B7/085
Abstract: 938,535. Cameras with automatic exposure control. EASTMAN KODAK CO. May 24, 1962 [May 25, 1961], No. 20065/62. Classes 97 (1) and 98 (1). A cinematographic camera having a motor for driving film feed and shutter mechanisms and an objective diaphragm which is adjusted automatically in response to the intensity of light falling on a photo-electric device, has a diaphragm disposed in front of the photo-electric device, the diaphragm being adjustable automatically in response to changes in the camera speed by the displacement of a movable part of a govenor driven by the motor. In the embodiment shown, the cinematographic camera is provided with a photo-electric cell 1 in front of which there is a diaphragm 2 adjustable by a rotatable ring 3. The cell is connected to a galvanometer 4 with a pointer 5 which is visible in the viewfinder field adjacent a scale 6 of lens aperture numbers. The galvanometer sets the camera objective diaphragm blades 8, 9 in known manner. Diaphragm 2 is set according to the film speed and film sensitivity by means comprising a cable 11 fixed to ring 3 at pin 12 and passing over pulleys 13, 19, 15 to drum 15. As knob 22 is rotated to set for film sensitivity a slidable plate 17 on which pulley 19 is mounted moves to a position determined by cam 20 and thus varies the tension on cable 11 and causes ring 3 to rotate and set diaphragm 2. When knob 35 is rotated to set the film speed, cam 33 is adjusted together with the distance lever 29 which can rotate about its pivot 30, during which movement it rotates drum 15 through ratchet 15b and causes ring 36 rotated. Lever 29 is rotated either by moving lever 43 in direction B pin 47, on which abuts lever 29 and rotates it, or by a governor plate 27 which is moved in direction A during film movement and engages and rotates end 32 of lever 29 until the latter abuts cam 33.

Title: Particle classification based on thermal properties
Inventor: ROOS EDWIN HARM
IPC: B07C5/34
Filed: 1994-05-25
Abstract: Particles are classified according to their thermal properties by means of a method in which the first step is that of deriving a first matrix composed of first emitted heat energy values for the particles (16, 18) with the particles at a uniform temperature. This is achieved using a first thermal camera (22) to derive a thermogram which is analysed by a CPU (24). Next, the CPU calculates emissivity equalisation factors which equalise the values in the first matrix when the values are adjusted by the factors. Then the particles are heated or cooled, typically by an infra-read beam (26). A second matrix composed of second emitted heat energy values is then derived, by the CPU, for the heated or cooled particles, using a second thermal camera (28). The CPU adjusts the values in the second matrix by the earlier derived emissivity equalisation factors, thereby producing adjusted heat energy values for the particles. Finally, the particles are assigned classifications according to the magnitude of their adjusted heat energy values. The invention is applicable to recovering diamonds (16) from gravel (18). <IMAGE>
