Title: Composite concentric flexible sleeve joint for hot ducts - using abrasion resistant and insulating matls. in an expansion joint
IPC: F16L27/10
Filed: 1974-03-29
Abstract: Double sleeve coupling for enclosing an expansion joint between two conduits for circulating hot gases, has a concentric joint surrounded by an inner sleeve and by an outer sleeve of sufficiently greater diameter to be mounted with out mutual contact between the steeves. The inner sleeve is protected from abrasion by a porous metal cover. The outer and/or both sleeves should be impermeable to the hot fluid. The coupling is used for pipe or dust systems conveying combustion fuels or exhaust gases or smoke at fairly high velocities, moderate super-atmospheric pressures and temps. up to 1000 degrees C. The air gap between the concentric sleeves partially insulates the outer sleeve, allowing the higher gas temperatures to be used. Outer sleeves may be replaced without disturbing the inner sleeve.

Title: Separator for fluids in homogeneous mixture - fluids diffusing at different rates through porous screen
IPC: B01D53/22
Filed: 1974-12-23
Abstract: A device for sepg. fluids from a homogeneous mixture is claimed using a porous screen of material which provides differential diffusion rates for the fluids to be sepd. the screen is a thick, i.e. three-dimensional grid of woven wire mesh with a high internal voidage i.e. pref. bout 75% air space in the grid. The mixture is projected as a high speed jet at right angles on to one face of the screen and, on the opposite face, a central collector funnel coaxial with the jet gathers a fraction with a high concn. of the fluid which a lower diffusion rate while a surrounding annular area of the screen feeds into an outer collector a fraction of high concn. of the fluid with a higher diffusion rate. The screen material pref. comprises several, superimposed layers of woven mesh joined by wires woven in at right angles to the layers. Sepn. efficiency can be improved by operating a number of the above two-way sepg. devices as a multi-stage cascade series. Sepg. two or more fluids which have different rates of diffusion through a porous screen, the fluids can be in homogeneous mixture and may be two liquids or two gases. Extremely simple and inexpensive sepg. process with wide applications and the ability to be easily adjusted to precise sepn. requirements.

Title: Digital time-base correction for television receivers - uses analogue-to-digital conversion of picture signal controlled by oscillator
IPC: H04N9/896
Filed: 1975-03-14
Abstract: A digital time base correction system for television receivers is based upon analogue to digital conversion followed by memory storage. A digital to analogue converter is then used to operate on the memory output. The main feature of the system relates to the method used for controlling a triggered oscillator that is linked with the analogue-to-digital converter. The oscillator consists of an amplifier with a feedback loop with a time constant determined by an R-C network. Depending upon the state of an FET the oscillator operational period may be controlled. When the output of the picture synchronisation circuit goes low a bistable becomes zero and the FET opens allowing the oscillator to run. The oscillator output changes the state of a counter until a predetermined count is reached.

Title: Fibrous material dewatering roller press - with rings on edge of perforated bottom roller and scraper blades in grooves
IPC: C13B15/00
Filed: 1975-04-11
Abstract: A two-high roller press for dowatering of fibrous matl. such as sugar cane bagasse consists of a lower roller on a stationary shaft and an upper roller on a sliding bearing. The lower roller carries on a cylindrical core a number of rings of greater radial width than thickness. They form narrow and deep annular grooves in which scraper blades are arranged to keep the grooves clean. This prevents the clogging of the perforations by the fibrous matl. The extracted fluid can flow off without contacting the matl. again.

Title: Oil drilling pipe alignment system - uses upper and lower members with polar coordinate system
IPC: E21B47/022
Filed: 1975-04-28
Abstract: A device to measure the inclination of the axis of an oil drilling pipe, from the vertical, has an upper part and a lower part which are superimposed on the pipe. The upper part defines a system of coordinates to the pipe axis and a given fixed direction. A locating device on the upper part defiens a guide mark in the system of coordinates and, at the same time, an origin which is the vertical projection of the guide mark in a plane of the lower part. When the two parts are separated, the origin is no longer vertically aligned with the guide mark. A measurement system then determines the co-orinates of the origin in the new position.
Patent FR-2275923-A1 (FR)
Title: Rectangular section equalising connector for armature windings - has edge bending replaced by 180 deg twist in conductor
IPC: H02K3/16
Filed: 1975-05-29
Abstract: The pre-insulated equalising connector is cut to length, the ends bared and tinned, and formed to the correct winding pitch. It is then held across its wide side and the free ends twisted, each through 90 deg. in opposite directions to give 180 deg. of twist. The centre line of the twist is slightly offset from the narrow edge of the conductor. Thus a top and bottom coil side is produced without the need to bend the strip on edge, and consequent damage to the insulation leading to the need for reinforcement is eliminated. Cracking of the copper at the bend is also avoided.

Title: Thermoplastic resin made susceptible to surface oxidation - by addition of micronised rhyolite granules
IPC: C08K3/36
Filed: 1976-03-30
Abstract: Thermoplastic resins based on polyolefins, polystyrenes and poly(vinyl chlorides) have their properties improved by addn. of micronised rhyolite in the amt. of 1-7 (0.3-1.5) wt. % of the resin. The additive can be incorporated in the cold, in the factory before prodn. of the granules. The additive renders the resins susceptible to superficial oxidn., which improves their properties when applied in the plastics industry, e.g. in packages, sectional irons, pipers, etc. It obviates the need to use specialised equipment or treatments to achieve the favourable properties.

Filed: 1976-06-23
Abstract: The gas burner has a discharge chamber (3) which is 'T' shaped in cross section with a block (4) mounted on top, separating two rows of gas discharge holes (2, 2a). The block is rectangular in cross section, and the flames (11) travel upwards parallel to its vertical sides. At the top, the block terminates in a T shaped portion (14), giving a groove (5, 5a) each side. This groove gives an effective heat output for gas which is rich in nitrogen when the depth (L4) of the grooves and the height (L3) are approximately equal and when the height (L1) of the bottom of the groove from the base (3) is seven to nine times the depth (L4). The distance (e) between the centre line of the flame and the side of the block (4) is a tenth of the height (L1).
