Abstract: The invention relates to a method of preparing a low-­calorie butter-based spread, and to low calorie butter-­based products obtainable by those methods and provides:- a process for the preparation a low fat spread in which a lacteal fluid, preferably dairy cream, containing less than 45%wt butterfat is:
     a) enriched to 55%-75%wt fat,   b) diluted with an aqueous phase relatively free of lactose, and,   c) cooled and worked whereby phase inversion occurs and a spread comprising 30-60%wt of a fat results.   
     The use of a non-dairy aqueous phase enables the copper and lactose content of the product to be controlled avoiding microbiological and organoleptic difficulties. The presence of other dairy substances in the water phase, such as caseinate and/or whey proteins, is optional. The term "lacteal fluid" as applied to the starting material is intended to include relatively low fat creams and milks as well as 40% fat creams.

Abstract: A registration correction circuit for a solid-­state camera having a plurality of solid-state image pickup elements. One of the color video signals produced from the image pickup elements is selected as a reference signal, and pixel data of the color video signals other than the reference signal are electronically moved so that the pixel data of all the color video signals will agree in their positions. Movement of pixels is carried out by using coordinate transformation and interpolation technique: the coordinate transformation is used to shift the pixels by a multiple of 1-pixel pitch; and the interpolation is used to shift the pixels by less than 1-pixel pitch. The spatial frequency components reduced by the interpolation calculations are adaptively enhanced for each pixel in real time.

Abstract: A nuclear reactor coolant pump (18) has a casing (24) defining an inlet nozzle (48) for receiving a reactor coolant fluid, an outlet nozzle (50) for discharging the fluid, and a passage (51) interconnecting the inlet and outlet nozzles through which the fluid can flow in a main stream from the inlet nozzle to outlet nozzle. The pump also has a central rotor (32) with one end (32B) disposed adjacent the annular passage of the casing and opposite bearings (34, 36) rotatably mounting the rotor to the casing. A motor (38) is disposed about the rotor and between the bearings and is operable for rotatably driving the central rotor. An impeller (46) is mounted to the one end (32B) of the rotor in communication with the annular passage and the flow of fluid therethrough. The impeller rotates with the rotor to create a lower pressure at the inlet nozzle (48) than at the outlet nozzle (50) for drawing the reactor coolant fluid into the casing through the inlet nozzle and discharging the fluid from the casing through the outlet nozzle. A self-cooling arrangement (56) provided in the pump defines a fluid flow loop (58) in communication with the annular passage and in heat transfer relationship with the bearings and motor. The self-cooling arrangement is operable for diverting only a fraction of the fluid from and back to the main stream through the annular passage to cool the bearings and motor. Foreign particle deflectors (78) are provided to minimize passage of particles into the fluid flow loop.

Abstract: Methods and apparatus for improving the performance of general purpose computing systems that utilize exclusive and shared seize mechanisms to assure the integrity of shared data objects, records, or other unit of synchronization. Read (shared) accesses can be performed in such a manner as to improve system performance by utilizing a method comprising the steps of: (a) determining, for a particular shared data object to be read, if the object is subject to an exclusive seize prior to any attempt to read the object; (b) reading the object without causing a shared seize to be initiated if it was not subject to an exclusive seize as determined in step (a); (c) determining if the object is subject to an exclusive seize after reading it in accordance with step (b); and (d) determining if the object was subject to an exclusive seize while it was being read. If, as a result of performing the aforestated method, it can be concluded that the read took place without an exclusive seize immediately before, during and just after the read, then the data can be presumed valid. System performance is improved in such cases since the overhead associated with initiating a seize for the read is eliminated.

Abstract: An optical semiconductor includes a photo diode integrated with a transistor built on first and second epitaxial layers grown on a substrate. the first epitaxial layer is grown on the substrate from intrinsic material. The second epitaxial layer is grown doped on the first epitaxial layer. A separating area divides the optical semiconductor into first and second isolated islands. The separating area is made up of a lower separating area, a middle separating area and an upper separating area united to form a single separating area. The lower separating area is diffused at least upward from an interface between the substrate and the first epitaxial area. The middle separating area is diffused both downward and upward from an interface between the first and second epitaxial layers. The upper separating area is diffused downward from the surface of the second epitaxial layer. The photo diode is formed in the first island area, and the transistor is formed in the second island area. A counterdoped region in the surface of the substrate, at least below the first island, expands the depth of the depletion region of the photo diode. The separating area enters the substrate to a depth corresponding to the depth of the counterdoped region.

Abstract: In the present insufflating device the fluid pressure prevailing in the output line 22 of the device is continuously scanned and fed back to the control input 26 of a continuously controllable pressure regulator 19 interposed in the fluid line. In normal operation, this avoids any time intervals in which fluid is insufflated into the body in an uncontrolled manner, on the one hand, and abrupt pressure changes as are caused by switching an interrupt on and off or by switching between flow paths with different flow resistances, on the other hand. Furthermore, it is ensured that the pressure in the output line 22 cannot exceed the value set on the pressure regulator 19. <IMAGE>
