Title: Clocked logic array with memory cells
Inventor: DUNN WILLIAM
IPC: H03K19/177
Filed: 1982-08-05
Abstract: A clocked storage logic array is formed from a plurality of columns (25, 35, 45, 55) and a plurality of rows (26, 27, 29) disposed orthogonal to the columns. Logic cells (21 etc) interconnect selected columns and rows. Storage cells (28, 48) are operatively associated with some of the columns in the array, known as data columns (25, 45). Each storage cell (28 or 48) utilizes only two column conductors (20, 22 or 40, 42) which are time shared to provide a data path from a memory element in the storage cell to a specified row or rows and back from the row(s) through the same column conductors to the memory. A plurality of phase-displaced clock periods are generated which operate in association with the storage cells to enable the two column conductors to each storage cell to be time shared. The clock periods also cooperate with logic cells to cause selected rows to assume binary states determined by the binary state of interconnected columns, and vice-versa. <IMAGE>

Title: Balancing rotors eg. aircraft propellers by electrical measurement
Inventor: WIDDALL JOHN ALAN
IPC: G01M1/22
Filed: 1982-12-16
Abstract: An accelerometer coupled to the mounting of an unbalanced rotating propeller produces a signal containing a component indicative of the unbalance. This signal may contain noise components from which the useful component has to be extracted without too much alteration. The extraction from the accelerometer signal (A) of respective signals indicative of quadrature components of the useful part of the accelerometer signal is achieved by multiplying at 14 the accelerometer signal with one or other of rotatable member position indicative signals (P, Q) derived by a phase-locked loop arrangement (9, 10 and 11) and forming the average of the products so derived. This avoids the use of a fixed frequency band-pass filter which would then have to be manually corrected if the actual frequency varied from that associated with the filter or a manually tunable filter which would have to be tuned for each test. <IMAGE>

Title: Turbine shroud segments and turbine shroud assembly
Inventor: PASK GEORGE
IPC: F01D11/08
Filed: 1983-02-10
Abstract: A turbine shroud 15 for a gas turbine rotor blade stage 7 comprises shroud segments 25 made of a low strength metallic alloy of the "MCrAlY" type which is very highly oxidation resistant at elevated temperatures. The shroud segments 25 are supported by a structure in the form of a carrier ring 29 consisting of an alloy which retains high strength at high temperatures, and shroud cooling air chambers 53 are defined between the shroud segments 25, strengthening ribs (54 Fig. 2 not shown) of the shroud segments, and throttle plates 58 which also form part of the support structure for the shroud segments. Cooling air from chamber 49 is metered into shroud chambers 53 through holes 57 in throttle plates 58 so that the pressure in chambers 53 is only just enough to ensure exhaustion of the cooling air through holes 55 into the turbine passage just downstream of the rotor blades 7. This ensures not only low consumption of cooling air but also that the shroud segments are thrust outwards against their seatings on the throttle plates 58 by the higher turbine gas pressures upstream, the ribs (54) defining load paths which give the segments adequate distributed support to prevent overstressing or overstraining of the low strength alloy. <IMAGE>

Title: Moving belt filter
Inventor: SCOTT WILLIAM P
IPC: B01D33/04
Filed: 1983-10-05
Abstract: A filter for dewatering sludge comprises a moving foraminous belt (16) onto which the sludge, preconditioned with polyelectrolyte from pump (32), is fed along chute (15). Staggered obstructions (23) divide the sludge into discrete streams between which zones of the belt are substantially free of sludge to permit drainage of water therefrom. The sludge is then compressed between belt (16) and a second belt (18) which are directed around a series of rollers. A pair of floats (25, 26) rest on the belt (16) or on the sludge thereon, in respective zones between and aligned with upstream obstructions (23), and their respective vertical positions are compared to derive a signal which controls the polyelectrolyte supply pump (32), thereby ensuring that the sludge is sufficiently stiff not to spread laterally across the belt downstream of an obstruction (23) without excessive consumption of polyelectrolyte. The control box (31) also produces signals indicating excessive or lack of sludge on the belt. <IMAGE>

Patent GB-840307-A (GB)
Abstract: 840,307. Electric capacitors. EASTMAN KODAK CO. Dec. 29, 1958 [Jan. 2, 1958], No. 41842/58. Class 37. In a method of making a rolled capacitor by winding interleaved metal foil electrodes and dielectric films, the capacitor is heated to at least 227 ‹ C. to produce substantial shrinkage of the films and disorientation of less than 50% of the molecules in the films, the films being made of one of the planar molecularly oriented linear thermoplastic polyesters conforming to the recurrent formula where R is a bivalent radical containing the benzene nucleus and R<SP>1</SP> is a bivalent aliphatic radical containing from 2 to 8 carbon atoms. In the embodiment described a rolled capacitor includes polyester dielectric films 11, Fig. 1, and metal foils 13 loosely wound with terminals 15 inserted in known manner during winding. The body of the capacitor is then heat-treated for a period between ¢ minute and 10 minutes at a temperature between 227‹ C. and 247‹ C., whereby the polyester films shrink and the capacitor takes the form indicated in Fig. 4, the terminals becoming secured, and due to the fusion of the polyester films, where they are in mutual contact, the capacitor becomes sealed. The terminals are further secured by an adhesive applied to them prior to insertion, and a bonding agent, e.g. benzyl alcohol, may be employed to give additional strength prior to heat treatment.

Title: Centrifugal separator and method of operating same
Inventor: BOCCKINO HARRY GEORGE
IPC: B04B5/12
Filed: 1984-04-17
Abstract: A continuous flow device is disclosed for separation of particles of differing densities in a centrifugal force field. Very small particles of differing densities that are normally very difficult or impossible to separate in the usual commercial gravity separation devices can be separated because of the increased settling force due to the centrifugal force field and also the buoyant force on the particles of lesser density caused by a thickened slurry layer. A thin film of a slurry of solid particles of differing size and density travels over a revolving surface (20) of such configuration that the slurry flows in a substantially laminar manner. As the thin film of slurry flows along the surface, the particles of greater density tend to concentrate in the region next to the surface (20), while the particles of lesser density remain in or are forced into the fraction of the film closestto the axis of revolution (14). Before the film of slurry reachs the end (24) of the flow path it is passed over a splitting device (21) to separate the fraction of the film containing particles of greater density from the fraction containing particles of lesser density.

Title: Digitally processing a stream of signal samples
Inventor: DEMEURE ALAIN
IPC: G06F15/80
Filed: 1984-09-18
Abstract: A system for processing a stream of input samples (e.g. successive samples of an image to be analysed), each processing operation being a function of the values of several samples, comprises a plurality N of elementary processors (2n) which communicate one with another and each contain a computing unit (3n) and a memory (4n) containing certain samples. A sequencer (1) controls the N operators in the same way, and the means for write and read addressing (5n, 6n) of the N memories are such that several processing operations can be done in parallel by running the same elementary conversions simultaneously on batches of samples corresponding to pick-ups equidistant along the section of signal acquired. To enable this parallel processing to be done without storing any given sample in more than one memory, each memory (4n) is divided into two or more segments. Incoming samples are stored in the first segment of the first memory until that segment is full, then in the first segments of the second ... n th memories, then in the second segment of the first memory, and so on, - the full cycle repeating continuously. <IMAGE>
