Title: Scraper chain conveyors
IPC: B65G19/28
Filed: 1971-12-22
Abstract: 1370630 Scraper chain conveyers GEWERKSCHAFT EISENHUTTE WESTFALIA 22 Dec 1971 [22 Dec 1970] 59738/71 Heading B8A In a scraper-chain conveyer composed of a plurality of channel sections joined end-to-end, each channel section being composed of side walls adjoined by a horizontal floor, the side walls are of sigma-shaped cross-section with planar inner faces combining with the floor to form upper and lower guide paths 23, 40, for a scraper-chain assembly 24. The planar inner faces are composed of a first inclined face 21, extending outwardly from the floor, a second inclined face 25, adjoining the face 21, and extending therefrom inwardly relatively to the conveyer and a third near-horizontal face 29 adjoining said second face. The side walls 19, 20, associated with the faces 21, define a central U-shaped groove 12. Further grooves 32, 35, make easier the hot rolling of the sections. The surfaces 38, 36, 27 and 39 flanking the grooves 12, 32 and 35 are co-planar, and thus serve for fixing attachments 13 and 14, thereto. The sides of the groove 12 are inclined at 60 degrees so as to prevent rotation of a hexagon headed bolt 18.

Abstract: 1417269 Non-woven fabric MONSANTO CO 28 Dec 1973 [29 Dec 1972] 60084/73 Heading D1R An unbonded mat of nylon fibres is autogeneously bonded by (1) increasing the moisture regain of the fibres to at least 2% based on the weight of the fibres, (2) subjecting the mat to a gaseous atmosphere having a temperature of 10 to 49C and containing less than 2 % by volume of a hydrogen halide gas (hydrogen chloride is exemplified) and greater than 0.5% by volume of water vapour, but lower than the dew point of the water vapour-hydrogen halide gas mixture at the gaseous atmosphere temperature, the nylon fibres increasing their moisture regain to at least 3% based upon the weight of the fibres and absorbing at least 2% by wt. of the fibres of hydrogen halide gas, (3) pressing the fibres together while they contain water and hydrogen halide gas and (4) removing hydrogen halide gas from the fibres. In comparative example 6 in which the hydrogen chloride gas concentration is 5.5% and the water vapour concentration is only 0.3% the product is a poorly bonded fabric as judged by an abrasion test. Preferably the mat is formed by extruding continuous nylon 66 filaments alternating them and collecting them upon a foraminous conveyor staple fibre mats may also be used. In example 1 the mat, weighing 1 oz/sq. yd. (33.9 g/m<SP>2</SP>) was preconditioned in a 24C 60% relative humidity chamber for 40 seconds, exposed to the HCl/moisture atmosphere for 12 seconds, calendered at 190 pounds/linear inch and passed through a water bath to remove HCl. The calender rolls may be embossed.

Abstract: 1,177,590. Cathode constructions and materials. SIEMENS A.G. 18 Dec., 1968 [19 Dec., 1967], No. 60156/68. Heading H1D. An indirectly-heated dispenser cathode arrangement comprises a main dispenser cathode 1, consisting of a porous carbon member impregnated with a thorium-producing substance, e.g. thorium oxide, which is heated by the impact of the discharge from a secondary indirectly-heated barium-based metal capillary cathode 4, wherein the secondary cathode 4 and the main dispenser cathode 1 form the cathode and anode respectively of a diode system having a separately enclosed discharge space which can be evacuated by way of the porous carbon member together with the rest of the discharge vessel housing the cathode arrangement. The cathode arrangement may be used in a grid-controlled h.f. tube where the deposition of barium from the secondary cathode 4 on to the grid is prevented by its combining with the porous carbon member to form barium carbide. The porous carbon member may be a flat disc, or, as shown, may be a hollow cylinder closed at one end and with an insert 6 of molybdenum or pyrolytic carbon which serves as a target surface having a profiled shape to give a uniform temperature distribution over the carbon cylinder surface. The porous carbon member may be mounted on and sealed to a Ta or Mo foil 2, and supplementary gettering means may be provided in diode discharge space.

The polymers may be formed by aqueous emulsion polymerization and foamed in a single operation. The polymers of the ethylenically unsaturated acids may also be blended with other addition polymer dispersions. The polymers may be expanded in a mold. Exemplified polymers are terpolymers of tert. butyl acrylate, methyl or ethyl or n-butyl acrylate, and vinyl sulphonic acid, and tertbutyl acrylate and styrene or vinyl chloride, and vinyl sulphonic acid or acrylic acid.

Patent GB-2004443-A (GB)
Title: Voice codification system
IPC: G10L19/00
Filed: 1978-08-08
Abstract: In a voice coding system each vowel or consonant sound, or phoneme, is divided into repeated similar sections and the analog electrical equivalent of one of those sections is transmitted. If repetitive sections cannot be distinguished, e.g. during unvoiced consonants, a signal is derived from a section of predetermined length. The signal is transmitted in digital form together with signals indicating the number of sections in the phoneme, the intensity of the phoneme, the intensity of each of the repeated sections of the phoneme, any pre-equalisation applied to the speech, and phoneme change. On reception the analog electric equivalent signal is recovered, stored, level controlled, equalised, and repeated the appropriate number of times until a phoneme change is indicated.

Title: A Spark Timing Control Device for an Internal Combustion Engine
IPC: F02P5/152
Filed: 1980-06-16
Abstract: The spark timing control device comprises a vibration sensor 1 for detecting knocking connected to circuits 100-400 for eliminating background noise signals from the engine and providing an output signal when the integrated knock signal exceeds a reference level. The knock signal is supplied to a circuit 500 which generates a step waveform having an amplitude which increases with increasing knock.

Title: Process for Producing Aqueous Solution of Calcium Nitrite
IPC: C04B22/08
Filed: 1980-09-29
Abstract: An aqueous solution of calcium nitrite having high purity and concentration is obtained by contacting a nitrogen oxides containing gas (5 to 12 vol %) with a high concentration aqueous slurry of calcium hydroxide (20 to 40 wt %) by feeding the gas under an elevated pressure to prevent a concentration of said slurry, the unabsorbed gas being oxidized. The resulting gas is fed to the slurry obtained in the first instance so as to convert the residual calcium hydroxide to calcium nitrite without forming a calcium nitrate by-product. The process is preferably carried out as continuous process having a first reaction zone and a second reaction zone.
