Patent SE-7906633-L (SE)
Inventor: GLOOR P
IPC: B25D9/08
Filed: 1979-08-07
Abstract: The invention aims to improve the power/weight ratio of a two-stroke engine employed as the prime mover in a drilling and chiselling hammer 1 (sometimes also known as a percussion tool) of the kind in which percussion impacts are transmitted to a tool holder 3 of the tool by way of a percussion piston 9 which is reciprocated by the engine, thereby to enable the tool to be lighter, so that it can more readily be manipulated in the case of a hand-held tool. To achieve this improved efficiency, crank 7 of the percussion piston 9 is accommodated in a chamber 1a into which air is drawn by way of a non- return valve 11 upon movement of the piston 9 towards the top dead-centre position and from which air is displaced, under compression, through a pipeline 13 to an entry slot 1e of the cylinder 1c of the engine. <IMAGE>

Abstract: Additives for lubricating oils are obtained by reacting ammonium tetrathiomolybdate and a basic nitrogen-containing substance, preferably in the presence of a polar promoter, to form a sulfur- and molybdenum-containing composition which when incorporated in a lubricating oil inhibits oxidation, imparts antiwear and E.P. properties and/or modifies the friction properties of the oil. The polar promoter, when used, is preferably water. The basic nitrogen-containing substance may be a succinimide, carboxylic acid amide, hydrocarbyl monoamine, hydrocarbyl polyamine, Mannich base, phosphonamide, thiophosphonamide, phosphoramide or dispersant viscosity index improver.

Abstract: An improved battery separator for alkaline battery cells has low resistance to electrolyte ion transfer and high resistance to electrode ion transfer. The separator is formed by applying an improved coating to an electrolyte absorber. The absorber, preferably, is a flexible, fibrous, and porous substrate that is resistant to strong alkali and oxidation. The coating composition includes an admixture of a polymeric binder, a hydrolyzable polymeric ester and inert fillers. The coating composition is substantially free of reactive fillers and plasticizers commonly employed as porosity promoting agents in separator coatings. When the separator is immersed in electrolyte, the polymeric ester of the film coating reacts with the electrolyte forming a salt and an alcohol. The alcohol goes into solution with the electrolyte while the salt imbibes electrolyte into the coating composition. When the salt is formed, it expands the polymeric chains of the binder to provide a film coating substantially permeable to electrolyte ion transfer but relatively impermeable to electrode ion transfer during use.

Abstract: The invention relates to a method of and apparatus for separating the specifically heavier component from a flow of a medium, charged with suspended particles, by means of centrifugal force, in which the flow is first of all deflected and then in direct contact with regard to the inner curvature region an eddy separation is effected with an eddy (17), rotating in an eddy chamber, and central sucking off (8) of the specifically lighter component, for which purpose the flow is introduced, in a tangential flow (12) extending over the entire width of the chamber, into the eddy chamber, and cleaned medium, rid of the separated particles, leaves the eddy chamber through two immersion tubes (8) which extend in mirror-image manner in the centre of the eddy chamber. The invention relates to a method and apparatus, in which respect the separated particles pass without assistance by a flow directly from the eddy chamber into a bunker (7). The particles to be separated are carried out by the effect of the secondary flow with an axial direction component (18) through openings (14), arranged in the axial boundary walls (15), without a sucking- off acting from the outside. The direct separator can be used in a dust separating system having multiple eddy chambers. <IMAGE>

Abstract: In order to enable the automatic detachment of a towing hook (15), this is controllably fitted in housing (12), which is fitted to a rotating mounting (10).  The housing includes a hydraulic device, whose cylinder (21) is connected to the hook, by a link (25).  The hydraulic device's piston is fixed to the housing and oil pressure in the device normally pushes out the piston relative to the casing, whereby the hook (15) is held in its active position.  A valve (29) ensures that the oil pressure in the cylinder does not exceed a certain value.  When this occurs, the valve opens so that the cylinder empties and the piston is drawn into the cylinder of the casing.  At the same time, the hook (15) is swung down from its active position so that the towrope is released.<IMAGE>

Abstract: A tobacco smoke filter having an improved tar/carbon monoxide ratio is disclosed. The filter is obtained by sealing off the center portion of the filter with an inner member which is impermeable to the passage of smoke, thus directing all of the smoke to the periphery of the filter. In one embodiment, the inner member is formed as a thin walled tube of a material such as polypropylene, with the tube being crimped to seal one end of the tube. The crimped tube is then overwrapped with a smoke permeable material.

Abstract: The invention relates to transparent dimensionally stable water-soluble non-tacky free-flowing and essentially non- hygroscopic detergent pellets, together with a process for their preparation. These pellets consist of a matrix that comprises A) a soap component, B) a synthetic detergent component, C) a solvent component and D) a water component. The soap component A) accounts for 15-50 wt-% of the matrix and comprises salts formed by C6-C22 fatty acids and alkali metals, alkaline earth metals, ammonium or amines. The synthetic detergent component B) accounts for 10-65 wt-% of the matrix and comprises at least one water-soluble anionic surfactant chosen from a group comprising anionic organic sulphonates, anionic alcohol sulphates, anionic ether sulphates, anionic ether phosphates and anionic aliphatic surfactants. The solvent component C) accounts for 10-45 wt-% of the matrix and comprise a non-volatile organic solvent with a boiling point of at least 100 degrees C, at least 10% of which consists of a water-soluble dihydric alcohol. The water component D) accounts for 1-35 parts of every 100 parts of the said matrix. The pellets in question are prepared by heating the composition to a temperature that is above its solidification point in order to convert the material into droplets, which are then made to solidify during their free fall at least to a substantial extent.

Abstract: The method for controlling a fluid flow in a primary circuit in relation to that in a secondary circuit involves probing the return flow temp. in the primary circuit. Also, the outflow temp. of the secondary circuit is adjusted to a theoretical value, with heat being transferred via a heat exchanger between primary and secondary circuits. - The secondary circuit (S) is probed whether or not there is a fluid flow, and when a flow occurs, a first valve (MaVe) is opened in the primary circuit (P). The heat exchanger outlet temperature (T3) in the primary circuit is probed with a second valve (TeBe) which is temp.-controlled and series-coupled to the first valve. The second valve opens to an extent proportionally greater as the primary circuit outlet temp. decreases below the theoretical value. The second valve closes when that temp. is at or in excess of the theoretical value.(3)

Abstract: An improved method for the recovery of para-aminophenol from crude solutions thereof such as obtained by the catalytic hydrogenation of nitrobenzene in an aqueous acid reaction medium. The method comprises neutralizing the cold, acidic solution containing the crude para-aminophenol whereby a very fine fluffy para-aminophenol precipitates. When an aromatic amine selected from the group consisting of aniline, mixed toluidines, ortho-toluidine, mixed xylidines, and mixtures thereof is admixed therewith an upper layer containing the para-aminophenol suspended in the aromatic amine forms when allowed to settle. A clear lower layer containing about 70 to 90% of the ammonium sulfate solution is separated and discarded. The upper layer which contains the aromatic amine and the para-aminophenol can be used as a source of para-aminophenol for producing para-aminophenol derivatives such as diaryl para-phenylenediamines.
