Title: Phosphate coated iron powder and method for the manufacturing thereof
Inventor: JANSSON PATRICIA
IPC: C23C22/03
Filed: 1998-08-24
Abstract: The invention concerns a novel low oxygen powder comprising particles of a base powder consisting of essentially pure iron having an insulating oxygen- and phosphorus-containing barrier. The oxygen content of the new powder is at most 0.2% by weight higher than the oxygen content of the base powder, and the ratio O:P is between 30 and 1, preferably between 15 and 2 and most preferably between 10 and 3 as measured by the ESCA method. The invention also concerns a new method of preparing an iron-based powder comprising the steps of preparing a base powder consisting of a water atomized iron powder or a sponge iron powder, subjecting the mixture to treatment with a solution of phosphoric acid in an organic solvent and drying the obtained mixture, whereby the solution of phosphoric acid is sprayed on the base powder while being mixed.

Filed: 1990-10-09
Abstract: Method and device designed for arranging and packing plants and their respective root lumps. The method and device are employed in relation to plants which have grown in a seedling unit containing a large number of plants and soil lumps arranged in a plurality of rows and lines adjacent each other and in uniform rectilinear check pattern. After removal of void soil lumps containing no plants and soil lumps containing badly developed plants, the remaining healthy plants are gripped and placed in channels in the same pattern they were in in the seedling unit with a separate channel for each row. The plants are then conveyed in the channels from an input end towards an output end, and gaps between the plants are eliminated in the channels not later than upon reaching the output end. A certain number of plants so collected are then removed from the channels and placed in a transport container.

Abstract: It is proposed to complement a device for data acquisition in a vehicle by means for manually inputting information which characterises an accident or an accident-like situation. In particular, there is provision for the storage of this information to be triggered by actuating the key (2) of the hazard warning signal generator (1) of the respective motor vehicle. For this purpose, the signalling lines of the flasher lights (8, 9, 10, 11) of the right-hand and left-hand vehicle side are logically connected via an AND element (21) and the output level of a retriggerable, monostable multivibrator (22) connected downstream is continuously interrogated by a microcomputer over a specific hunting time. If the level is maintained, the microprocessor (19) controls the permanent storage of identification data in the data memory (24) of the relevant data acquisition system. <IMAGE>

Abstract: 1,203,644. Weft stop-motions. S. A. O. RYDBORN. 6 Sept., 1967 [7 Sept., 1966], No. 40639/67. Heading DIE. A stop motion for a machine such as a shuttleless loom in which a weft thread is drawn intermittently from a supply is operated on cessation of an electric signal produced by the running of the thread over a sensing element during a thread detection period. The senser is preferably of the piezeoelectric type, Fig. 8, in which the thread runs in a slot 21 on a rod 23 of piezeoelectric ceramic material held between springs 24, 25. A high frequency electric signal of the order of 30 kilocycles is produced in the cable 32. This signal is applied to the circuit of Fig. 1, first passing through three amplifier stages TR1, TR2, TR3 to give a signal in the form B. This amplied signal then passes to a circuit TR4-TR7 which controls a relay 20 in the machine circuit to stop the machine on cessation of the signal at A on breakage of the thread. To ensure that the relay 20 is not operated during the periods between weft insertions when the thread is not being withdrawn a mechanical switch 30 driven by the machine controls the circuit TR4-TR7. In addition a parallel photoelectric circuit 40, operated by a member 50 attached to the weft inserter, also controls the relay 20 to ensure that, on release of the thread at the selvedge, the relay 20 is not operated. Other forms of senser may be used such as a piezoelectric generator of the crystal type, a photoelectric signal generator, a resistance signal generator or a capacitor signal generator.

Abstract: An asbestos-cement composition contains up to 70%, preferably 10-40%, asbestos fibre which has been treated in air suspension with an atomized spray of Na and/or K silicate solution (see Division C1). Cement, asbestos, and optionally silica, may be present in the proportions 5 : 2 : 3 resp. by weight.  The treated asbestos may be dispersed in an aqueous slurry of cement and consolidated, e.g. by transferring the slurry solids on to a revolving element where a laminated composite article is built up.ALSO:The filtration characteristics of asbestos are improved by applying an atomized spray of a sodium and/or potassium silicate solution on an air suspension of asbestos to deposit 0.1 to 4% on the fibre.  The solution may contain 3 to 20% silicate having SiO21M2O ratio of 1.6 to 3.75.  Asbestos from screw feed regulator 1 is transported on conveyer 2 to fibrizer 3, e.g. a willow.  The silicate spray from 5 is directed into the willow feed opening, and coats the fibre, which is then pneumatically conveyed to cyclone separator 6.  A moisture content of less than 8% may be ensured by extending this air passage or re-suspending the fibre in a current of air, which may be warm, e.g. at 150 DEG  F. This drying step may be omitted when the coated fibre is used to form asbestos-cement articles by dispersing in an aqueous slurry of cement and transferring the slurry solids to a revolving element where a laminated <PICT:1002361/C1/1> composite article is built up.  Treated asbestos or asbestos-cement slurries were shown to have improved rates of filtration (the latter having an asbestos:silica:cement ratio of 2:3:5).ALSO:Asbestos paper is manufactured from asbestos fibre which has been treated in air suspension with an atomized spray of Na and/or K silicate solution (see Division C1), by forming sand sheets with starch or latex binders.  Asbestos-cement boards are made by dispersing the treated fibres in an aqueous slurry of cement, collecting and withdrawing a wet layer on a collector roll, transferring it to a revolving accumulator element and building up a laminated composite article.

Abstract: 1,172,390. Photo-electric absorption analysis. INCENTIVE RESEARCH & DEVELOPMENT A.B. Dec.16, 1966 [Dec. 22, 1965], No. 56408/66. Heading G1A. In absorption analysis of a sample, a movable filter is used to provide pulses of radiation alternating in frequency between one which is partially or entirley absorbed by the sample and another unaffected by the sample. The pulses are separated into groups corresponding to the different frequencies and the ratio of the amplitudes of the two groups is recorded. Ultraviolet light from a hydrogen lamp 1 is focused by lenses 2, passed through filters 3 and reflected by mirror 4 before passing through the rotating filter arrangement 6, 7 driven by a motor 8. A rectangular crosssection beam is provided by diaphragm 9 and the beam is passed through the sample. This is contained in an electro-phoresis tube 10 which is rotated about its axis by belt 21 and reciprocated across the beam. Current is supplied to the tube via supports 19, 20. The beam then passes through a filter 12 removing visible light, before reaching the photo-multiplier 11. Signals from the photomultiplier are fed to a recorder 13 via alternate channels of a two-channel recorder system including amplifiers. A switch synchronized with motor 8 arranges that the signals due to radiation which is absorbed by the sample pass through the sample channel and signals due to radiation unaffected by the sample pass through the reference channel. The recorder records the ratio of these signals as a value proportional to the absorption of the sample. A feedback loop from the reference channel to detector is provided to maintain the reference signal amplitude constant. Instead of using a movable sample tube, 10, a stationary through flow cuvette and a scanning light beam may be used.
