Title: SRAM memory array scan chain testing
Inventor: GENTNER THOMAS
IPC: G01R31/3185
Filed: 2009-03-11
Abstract: Serialized data is inputted into the memory arrays via a single scan in pin and data is read from the memory arrays via a single-pin access point for debug processes. A logical sequence of the arrays 20, 24, 28 is built up and a connection is made between the output register 18 scan-out pin of a current array 20 with the output register 18 scan-in pin of a subsequent array 24 which allows data to be transferred from the scan in pin through the memory arrays and their input and output registers to the scan out pin. A concatenated scan bit chain 31 is obtained from the output registers 18 of the arrays 20, 24, 28 thus generating a seamless packed scan chain 31. A single scan chain for memory arrays with different sizes is built up.

Title: Acoustic fluid analysis method
Inventor: DIFOGGIO ROCCO
IPC: E21B49/10
Filed: 2007-12-14
Abstract: A method of analyzing acoustic data comprising, determining fluid sound speed through connate fluid. The method involves sampling the fluid, sending an acoustic signal into the fluid between a first and a second reflective interface. Data is recorded that represents acoustic signals over time as they are reflecting from the interfaces. A smoothed first derivative with respect to time of the cumulative sum of squares (CSS) of the filtered amplitude data is determined. This first derivative is cross correlated to the time-shifted versions of itself.

Title: Steering flying vehicle by control of aerofoil
Inventor: MCINTOSH SIMON
IPC: B64C3/52
Filed: 2009-07-21
Abstract: A craft comprises a canopy 1 defining a lift-producing surface 1A shaped to have double curvature. An engine 2 is supported beneath the canopy 1 driving a radial fan impeller 3. Aircraft are usually provided with moveable aerofoils as a means to control direction and orientation. On fixed wing craft these commonly take the form of hinged vanes or ailerons. In Coanda craft the vanes are usually hinged to the skirt of the canopy. The invention offers an alternative method of steering in which the aerofoil is flexible and that the craft has means to cause the aerofoil to flex. Actuators 5 act cause threaded rods 4 to flex a selected portion of the canopy 1 so as to cause the craft to pitch or roll. The airfoil may be formed from a single integral piece formed from a composite material having a varying composition so as to give different portions of the aerofoil different levels of flexibility. The craft may be submersible.

Title: Improvements in and relating to resinous polymerization products
IPC: C08F12/34
Filed: 1943-06-22
Abstract: Heat - convertible, soluble, fusible partial polymers are prepared by heating a solution of p or m-divinyl benzene in a p- or m-dialkyl benzene having at least two carbon atoms in each alkyl group, in the presence of both a catalyst and an inhibitor of polymerization for a period less than that required to cause gellation.  The partial polymer may be precipitated by the addition of a non-solvent, e.g. methyl alcohol, ethyl alcohol or glycol, or by evaporation of the solvent.  Suitable catalysts are ozone, ozonides, hydrogen, barium, sodium, acetyl, lauryl, stearyl, benzoyl, acetone, triacetone, diethyl, ethyl hydrogen and acetylbenzoyl peroxides, perborates, persulphates, perchlorates, aluminium chloride, methacrylic and hydrofluoric acids, cobalt and manganese resinates, linoleates and maleates. Suitable inhibitors are copper, sulphur, aniline, diphenylamine, naphthylamine, phenols, cresols, xylenols, naphthols, aminophenols and aminonaphthols.  In the example, p- or m-divinyl benzene dissolved in p-diethyl benzene, benzoyl peroxide and freely reduced copper gauge are refluxed for 30 minutes and the viscous solution poured into methanol.  The precipitated polymer was soluble in toluene, ethyl acetate, ethylene dichloride, styrene and methyl methacrylate.

Abstract: 1,114,262. Ropes. G.K.N. SOMERSET WIRE Ltd. 8 June, 1965 [11 March, 1964], No. 10232/ 64. Heading D1T. [Also in Division B3] A steel strand or rope is heated and stretched after it leaves a stranding die in order to improve its tensile properties. The temperature of the rope or strand is made sufficiently high to produce permanent elongation. In Fig. 1 wire or strands 15 pass via a lay plate 14 to a stranding die 11. The die is imensioned to provide frictional resistance to the strand or rope 16 which is thus stretched by a capstan 17 about which it passes. A low voltage heating current is passed through the rope 16 from the die 11 to the segmented surface of the capstan 17 as described in Specification 748,357. Alternatively one idler and one haul - off pulley or drum may be provided between the die and the capstan and the heating current caused to flow from the idler both to the die and to the haul-off pulley or drum. The grooves on the haul-off drum- and capstan would be of progressively decreasing size to allow for contraction of the strand or rope. A device such as a water quenching arrangement cools the strand or rope as it passes to the capstan or haul-off drum.

Title: An improved manufacture of lubricating grease compositions
Filed: 1942-07-22
Abstract: 578,916. Lubricating greases. STANDARD OIL DEVELOPMENT CO. July 22, 1942, No. 10238. Convention date, July 19, 1941. [Class 91] A lubricating grease composition comprises a metallic soap grease having added thereto petroleum hydrocarbon resins derived from dewaxed de-asphaltized petroleum lubricating oils having a viscosity index of' over 60. Such resins may be derived from de-waxed, de-asphaltized petroleum lubricating oils by propane extraction. When added to soap greases they have the effect of imparting high viscosity and film strength at high rates of shear while being capable of handling without difficulty in ordinary pressure equipment at low rates of shear. The cohesiveness, adhesiveness and resistance to the action of water of the resulting soap grease are also improved. The soap may be a calcium soap, an anhydrous sodium soap, or a mixed metallic compound, and the preferred proportions are from 10 to 150 parts of petroleum hydrocarbon resins to 100 parts of metallic soap grease. In an example, 80 parts of a calcium soap grease containing 90 per cent. of mineral lubricating oil of 300 S.S.U. viscosity and 10 per cent. of calcium soap are mixed with 20 parts of petroleum hydrocarbon resin of 95 Viscosity Index obtained from Pennsylvania bright stock by propane extraction; it is stated that this grease is virtuallv unremovable by ordinary means when applied to a smooth metal surface.

Abstract: 626,544. Condensers. TELEFONAKTIEBOLAGET L. M. ERICSSON. April 18, 1947, No. 10409. Convention date, April 18, 1946. [Class 37]  Condensers a are cooled by a medium, e.g. water or air, in forced flow in cooling chambers b, the greatest part of the exterior surface of which is adapted to lie against the walls of the condensers, both chambers b and condensers a being formed as separate containers so that the cooling medium does not contact the condenser walls. The chambers b and condensers a comprise closed hollow discs, alternately stacked between end members d and secured by bolts e. Tubes c serve to supply and evacuate the cooling medium. When liquid is the cooling medium the chambers b, which may be of copper, are divided into two compartments by a metal sheet placed intermediate of, and parallel to, the end walls of the disc, and have a central hole. A metal strip shaped as a spiral is welded to each side of this plate, to form a continuous channel for the cooling medium in the disc b between inlet and outlet. If air is used as the cooling medium, the spiral metal strips are replaced by separate curved strips and the central hole in the metal sheet is dispensed with.
